Wood echidna (Dendroglossus scandens)
Order: Monotremes (Monotremata)
Family: Echidnas (Tachyglossidae)

Habitat: tropical rainforests of Meganesia.

Picture by Alexander Smyslov

Climatic change in Neocene has strongly affected upon life of various Earth inhabitants. Some of them had to abandon their habitats, other oness had died out, and third ones had received great opportunities for evolution and had turned to prospering species. Humidifying of climate has caused reduction of desert areas and expansion of tropical rainforests zone. Some of inhabitants of open spaces have to found convenient places for life in forests, and than evolved to true wood inhabitants. In Australia which even after intervention of humans has kept an originality of fauna and flora, amazing abilities to adaptation were shown by echidna - the inhabitant of savannas and light forests. It had turned to true wood inhabitant, and besides it had changed to the excellent tree-climber.
To see such animal on the tree is not so such unusual thing as it seems at first sight. Among tree-climbers in different continents there were kangaroo, porcupines and even ground tortoises, not to mention toads and frogs. Therefore the wood echidna of Neocene epoch, sauntering along tree branches, does not seem as something unusual on their background.
This is rather large animal: its body length is up to 70 cm, heads with long proboscis is about 30 cm long. Slowly moving in tree crones wood echidna outwardly resembles a hybrid of bear and anteater. The wood echidna had kept characteristic shape of these animals, but had got additional features of adaptation to clambering habit of life. Its paws which are quickly digging off the firm dry ground, now equally easily break rotten wood or strong cover of termitary. Claws becoming more bent cling to bark and branches, permitting the animal to make walks at 30-meter height so easily, as if on firm ground. For more tenacious grip thumbs on forepaws began to oppose partly to fingers. On hinder legs feet are turned back, but it at all does not prevent this animal to move. Even on the contrary to it, using such feet it is easier to climb down headfirst along the tree trunk. The little toe on hinder legs became a certain analogue of the thumb: it can be opposed to other toes too and serves for branch gripping. This animal is very strong: by paws the echidna breaks trunks of trees beginning to rot and turns out from trunk thick boughs, searching for ants and termites.
Body of the wood echidna is massive and heavy-build. The tail of animal is very short; it serves practically only for fat accumulation.
The muzzle of this echidna is long, tiny mouth opens on its tip. Main food of animal includes insects, usually ants and termites, and the main instrument of their catching is the long tongue covered with sticky saliva. Except for ants and termites, the echidna eats larvae of beetles searching them in pierced trunks of dead trees, and also insects living among epiphytic plants. The wood echidna is able even to plunder trap leaves of insectivorous plants, catching from them insects floating in digestive liquid secreted by leaves. Sometimes it simply drinks this digestive juice with insects. One more dainty for the echidna includes bird eggs. Having found a nest, the echidna drives hatching bird out from it, accurately pierces an egg-shell by claw tip and licks by tongue the egg completely. The animal exhausts all eggs in nest though sometimes it is attacked not only by nest owners, but also by their numerous neighbours have flied to help. But what can birds make with the prickly robber surpassing them many times in weight?
Eyes of the wood echidna are very small, and auricles are not present at all. This animal is short-sighted, and the prickly armor perfectly protects it from any predator of Australian and New Guinean woods, therefore the wood echidna can not react (at least, externally) to loud alarm cries of wood inhabitants. But sense of smell and touch at it are very sharp: the animal easily will feel, as on branch any bug or spider creeps, not seeing it at all.
Colouring of animal began more contrast, than at its ancestor: needles are ivory-colored, top of body is light, and stomach is dark, covered with short thin fur. At the wood echidna there is very dense and thick skin, therefore stings of ants and termites are not harmful to it. Even army ants killing all alive on their way, do not harm this phlegmatic animal: unless they will inflict some stings to sensitive proboscis or between toes. The animal has natural immunity to their poison, therefore the echidna does not avoid their attacks: such attack does not harm to it, and in it there is even such benefit – ants at the same time kill blood-sucking insects in wool of the huge echidna. If insects (and also larger enemies) appear too importunate, the wood echidna sprinkles out a jet of musk liquid from special glands. Its sickening smell easily will drive off the most persevering predator.
The wood echidna is real wood tramp. It has no precisely bordered territory, and does not protect residence from neighbours. Some animals can peacefully food on the same tree, and even to ravage one termitary in common, not paying attention against each other. During such meetings pairing happens more often. Courtship ritual at the wood echidna is not present, and the breeding season lasts all the year round.
Not changing traditions of ancestors, wood echidna lays eggs. In its clutch there are 1 - 2 rather large eggs (with small chicken egg-sized ones), covered with white skinny shell. During formation of eggs because of hormonal influence the cross skin plica on the stomach of the female is increasing and turning to brood pouch. The female lays eggs, lying on back so that the tail appeared above a head. Then the egg rolls down to the pouch itself from oviduct. The incubating lasts about three weeks. Cubs hatch underdeveloped, looking more similar to embryons. They lick milk, squeezing from pouch walls. Usually from two cubs only one cub survives. It grows quickly, and at the age of two months (when it leaves mother’s pouch), the cub weighs already about half-kilogrann. It is covered with grey naked skin, but at it the short proboscis characteristic for these animals is visible. Claws of it still soft and short but after the cub has left the pouch, it literally starts to increase from different directions: practically simultaneously at it needles, wool and claws grow. While the cub is still small, its unique protection is musk liquid with which it excretes plentifully at a fright. The female regularly visits it (approximately twice per day) and feeds with milk. For this purpose it lies down on back in forked crown of branches, and the cub licks off the milk flowing down from pouch to stomach. But gradually the cub also starts to catch insects. At the age of three months the cub already starts to wander in wood canopy with mother, studiing to swarm up lianas and to search for insect nests. At the age of eight months it reaches length about 70 cm and already is completely independent. At the age of 20 months the young female already can lay the first egg and this surprising animal can live up to the age of 60 - 70 years.

Spurred Echidna (Plectroechidna toxica)
Order: Monotremes (Monotremata)
Family: Echidnas (Tachyglossidae)

Habitat: Forests of northern Meganesia.
The Neocene is, in some ways, much like the Holocene, in other ways not. The disappearance of humans is notable, but nature has carried on regardless. Some animals present in the Holocene have diversified, yet stayed fairly similar to their original ancestor. Some monotremes are a good example of this.
Echidnas of the Neocene are noteworthy for the presence of arboreal, giant, and even small burrowing forms. However, many have kept to the original mastery of their kind, the consumption of social insects. The forests of northern Meganesia hide one such creature, the Spurred Echidna. Outwardly it is very similar to its ancestor, with the exception of one remarkable feature, venom spurs. Venom spurs were typical of almost all primitive mammals, including monotremes, and simple atavisms were all that was needed to reactivate the vestigial spurs of echidnas into working ones, like the platypus.
This animal looks similar to the Holocene short-beaked echidna. It possesses spines slightly shorter than its ancestor, they are a secondary defense, spurs being a more effective deterrent. It's shape is typical, a squat body with sprawling limbs, it is about 30 cm long and weighs generally around 2 – 4 kilograms. It has a pointed rostrum, its fur is dark brown, and partly covers the spines. Its diet is mostly social ants and termites, but sometimes other insects.
Why has it grown the extra defense of a spur? Possibly because of the presence of rather large and fairly intelligent predators, that may be able to expose the animal's underbelly, Marsupial Panther, and the flightless Yagil bird both do this.
The spur is situated on each ankle, and is long and yellow. When approached by a predator, Spurred Echidna first produces a loud hiss, almost like a snake (echidnas of human epoch were only able to make a quiet hiss through the nose). It can also attack from a distance by spraying venom with the spurs. If the predator grabs the echidna, it will actively defend by stabbing with spurs. The venomous sting of the spur is not only very painful, but causes fatigue and sickness that can last some days.
Breeding takes place during the dry season, when floodwaters are gone, and suitable dry bedding is available for nest making. Females and males secrete a musky odor from the cloaca that allows them to find one another. Many males may pursue a female at once, but she will deny unsuitable males by showing her spines. As with the modern echidna, the penis is strangely shaped, similar to that of reptiles. 2 or 3 eggs are layed into her pouch about a month after copulation. Babies are small, and blind, and are suckled and raised in the nursery burrow. The milk is rich, and the babies grow relatively quickly, leaving the burrow when spines and spurs are fully developed.

This mammal is discovered by Timothy Donald Morris, Adelaide, Australia.

Crested Echidna (Neoglossus spinosa)
Order: Monotremes (Monotremata)
Family: Echidnas (Tachyglossidae)
Habitat: savanna and open forest of central and southeastern Meganesia.

Pictures by Alexander Smyslov

Monotremes of the Neocene are considerably more varied than those of the Holocene. Both platypi and echidna occupy diverse niches, mostly consuming small animals, insects and forage.
The Crested Echidna is a fairly large echidna, being similar in size and shape to the long-beaked echidna of human times (Zaglossus). It is about 60-90 cm long, and weighs up to 14 kilograms. It has relatively long, almost erect legs for an echidna, suitable for walking long distances in search of its food, ants, termites, and beetle grubs. It has a long snout, and large claws, which aid it in digging open insect nests, or grub burrows. The most obvious feature of this animal, however, are its spines. It's back is covered in a large crest of very long spines, similar to those of a porcupine, such spines can be up to 40 cm long. Shorter, stouter spines cover the rest of the body, and the tail has a cluster of fairly long spines too. Its fur is a light, dusty brown, and the long crest spines are banded in black and white, serving as a warning for predators. Shorter spines are yellow. rostrum, face, and feet are covered in black skin.
For this newer kind of echidna, spines have been taken from their initial purpose of passive defense, to more active vigorous protection similar to some porcupines. Firstly, at sighting a predator, echidna turns around, erects spines, and makes abrupt whistling noises through its nose, this is a warning. Then it will confront a predator, facing backward, with spines pointed at the hunter, and will make violent thrusting motions and short, backward charges. If the predator gets too close, these motions will intensify, and the predator may be badly stabbed by such long spines. Unlike the porcupine, these spines are firmly rooted in the echidna's thick hide, and do not come off when driven into a predator. In fact, after stabbing a predator, the echidna will make efforts to extract itself (spines are not barbed), and retreat.
During the wet season, when plant growth and abundance of insects is best, females become receptive, and smell musky. Males will not stab each other, when competing for mates, but posture and shake their spines vigorously. After copulation, 1 large egg is layed into the pouch. The pouch is forward facing, and well developed, this species does not make a nursery burrow. The female carries the egg, and then baby, until the young is mobile, and large enough to follow her, spines grow soon after.

Starbill (Astrorhynchus condyluroides)
Order: Monotremes (Monotremata)
Family: Duck-bills (Ornithorhynchidae)

Habitat: lower reaches of rivers of southeast of Meganesia, Flinders Island in Eyre Gulf.

colorization by Alexander Smyslov

Climatic changes in Neocene favour to evolution of thermophilic and moistureloving species. The most part of territory of Australia in Holocene was covered by droughty deserts. In Neocene this continent had moved to the north and had joined to New Guinea forming unite continent Meganesia. Rivers supplying with water plains of the central part of Meganesia spring from the north and east of the continent. The Eastern Meganesia prospers due to large river system occupying the territory of former Murray River. It runs into extensive shallow-water Eyre Gulf filled with warmed up brackish water. Expansion of habitats stimulated the evolution of water inhabitants.
The genealogical branch of monotremes declined till the Cenozoic Era had received new opportunities in Neocene. The occurrence of productive ecosystems has allowed to evolve to the various specialized species of these primitive mammal. The large piscivorous duck-bill mergotherium (Mergotherium piscivorus) inhabits rivers, and in mountain streams its tiny aggressive relative ancistrotherium (Ancistrotherium radulus) lives. In lower reaches of rivers running into Eyre Gulf, and also at small Flinders Island, one more descendant of duck-bill, the starbill, lives.
This species of duck-bills resembles the American star-nosed mole in many respects – it leads similar way of life, and even has few common features in appearance. This is small (rat-sized) animal with powerful forepaws using for digging. Between toes membranes are advanced; the animal is nice swimmer. At this animal the swimming membrane on forepaws is reduced, and they are more adapted to digging, than forepaws of duck-bill. During the swimming starbill presses them to the body. Besides the starbill is able to climb on roots in mangrove thickets, and often catches ground insects and snails. The tail at starbill is weak and short – this animal swims with the help of strong hind paws.
The most original part of appearance of starbill is its beak, the family feature of duck-bills. Beak at this species is toothless, short and wide. But on it the set of sensitive leathery outgrowths grows; that’s why the beak of starbill resembles a little the snout of star-nosed mole (hence the name: Condylura – the American star-nosed mole).
This animal is protected from predators by poisonous spurs (it is one more feature inherited from duck-bill) colored bright orange. At males spurs are longer, than at females. Fur of animal is black or dark brown with contrast white marks on head and shoulders. The predator attacking starbill will remember its colouring, having received a painful prick of poisonous spurs.
Starbill lives in damp ground of riverbanks and in marshlands. By this feature it also resembles its prototype from the insectivores order. It eats various ground and water invertebrates – earthworms, leeches, snails and larvae of insects. The animal searches for them with the help of sensitive outgrowths on edges of beak. These outgrowths are rich in chemo- and electroreceptors, and permits to define presence of live creatures even in darkness. Under water the starbill closes eyes, and is guided exclusively with the help of touch sence and receptors of beak.
Starbill is a solitary animal. Each individual digs complex system of tunnels in riverbank. The nest for posterity rearing represents the long hole terminating in the nesting chamber. This chamber is located above maximum water level, and has an emergency exit.
In lower reaches of rivers starbills of different genders lodge in different places. Males prefer to live in territories completely filling with water during the inflow. Here the amount of forage is more, and for spending the night animal often uses any casual shelter. Females prefer to settle closer to riverbanks where their long-term holes will not be filled with inflow.
At Flinders Island the separate population of this species differing in smaller sizes (animals weigh approximately 20% smaller, than their relatives from the “motherland”) lives. Conditions of life at this island are more severe, than at the continent – permanent sources of fresh water are not present there. Therefore starbills of Flinders Island receive necessary moisture exclusively from food. Also at these animals there is stronger poison secreting in smaller amount.

Fat-tailed marsupial dormouse (Notoglis crassipyga)
Order: Paucituberculata (Paucituberculata)
Family: Caenolestids (Caenolestidae)

Habitat: far south of South America, Tierra del Fuego, Andes – areas of seasonal climate.

Picture by Alexander Smyslov

Marsupials represent the characteristic group of mammals of Southern hemisphere. They are diverse in Meganesia and in South America, but in Pleistocene opossums had penetrated for the second time into North America where they lived up to Miocene, and in Neocene they widespreaded up to Greenland, having evolved a separate hardy species. One more northern advanced post of marsupials is at Hawaii where these animals had appeared due to human activity and could go through the epoch of people domination on the Earth. But all the same at southern continents marsupials are more diverse, rather than free or involuntary immigrants to the north. They lead various habits of life and occupy diverse habitats: from humid tropical forests up to snow-covered tops of Andes and cold deciduous forests of Tierra del Fuego.
Representatives of caenolestid family are tiny insectivorous forms from South America. One species of this group lives even in wool of huge groundsloth rodents. One more unusual representative of this family lives in areas of temperate and cold climate of South America – it is fat-tailed marsupial dormouse. It is very large representative of family: an adult individual is guinea pig-sized one, but it looks larger because of long fluffy tail which exceeds length of other parts of body. Head of this mammal is large and bears small auricles and large bulging eyes.
Fat-tailed marsupial dormouse leads tree-climbing habit of life and lives in forested areas. Because of rather short paws it is almost unable to jump in branches and prefers to climb, clinging by hooked claws. The tail of this marsupial is partly prehensile – its tip can twist around of branches, and the animal can hang, fixing only on tail. The fur of animal has beautiful ash-grey color with white underfur. On head and shoulders fur is darker.
The mouth of this marsupial is full of pointed teeth: fat-tailed marsupial dormouse is omnivore and has obvious tend to carnivory. Its food includes small mammals and birds, and amphibians and lizards in summer season. Also it willingly eats the carrion, also even frozen one. Similarly to the majority of animals of such kind, it is a solitary species of primitive behaviour, displaying aggression to relatives almost the year round, except for time of hibernation and courtship season.
Fur of fat-tailed marsupial dormouse is dense, short and velvety in summer and growing much longer to winter. This animal is strongly eaten off in autumn; in tail and buttocks fat is laid (hence the specific name “crassipyga”, meaning “fat back”). With approach of steady cold weather this marsupial falls into the true hibernation. For this purpose fat-tailed marsupial dormouse makes the shelter – it covers a hollow with dry leaves and constructs grass-made fuse to stop up an entrance of the hollow.
During the hibernation the body temperature of animal falls up to a minimum; breath and palpitation are slowed down in great degree. In such condition animal spends approximately two thirds of winter. In second half of winter at the female cubs are born. Shortly before the birth moment physiological processes of female become more active. She clears pouch and licks wool. Female gives birth up to ten underdeveloped cubs independently reaching her pouch. This species has only six nipples, therefore the part of cubs perishes within one hour after birth. When all nipples are occupied by cubs, the female falls asleep again, but dream is less deep. She produces milk which is periodically sprinkled in mouths of cubs. They gradually grow and develop, and the female wakes up after winter dream having already well advanced cubs. Within the summer cubs grow and pass to adult diet. At the beginning of an autumn they become independent and reach sexual maturity at the third year of life. Life expectancy of this species is up to 30 years.

Marsupial sharp-toother (Carnomacropus raptor)
Order: Dasyuromorphia (Dasyuromorphia)
Family: Predatory marsupials (Dasyuridae)

Habitat: savannas and light forests of Meganesia.

Picture by Alexander Smyslov

Looking at this carnivorous creature, especially during its hunting, it is possible to think involuntarily, that dinosaurs have returned to Earth. But actually it is not so, though this animal by habits and constitution is very similar to reptiles missed for a long time from the face of Earth. The marsupial sharp-toother is very original animal, and in fauna of Earth of human epoch there were no analogues to it. It is animal about meter height at a shoulder and weighting up to 50 kgs, the huge descendant of small marsupial jerboas (Antechinomys). It has inherited and has developed characteristic carnivorous habits of ancestors, and increasing the size this animal has had an opportunity to attack not only small animals, but also to overpower even sheep- or antelope-sized animals. Marsupial sharp-toothers became original "cheetahs" of the Meganesian savanna attacking cursorial herbivores. They are solitaries but if they have mastered concerted group hunting, it would not be more terrible animal in Meganesia than this creature.
The constitution of the marsupial sharp-toother is adapted to fast chasing of catch: back legs of animal are advanced as well as at kangaroo, and armed with moderately long non-plungering claws (three claws on each foot). At short distances the animal can accelerate momentum up to 80 kms per hour, and at long distance it keeps speed about 40 kms per hour during tens minutes. Forepaws of animal are rather big, there are advanced long fingers with the sharp claws on them, permitting to grip and kill small catch. Tail of animal is long (the general body length is of 2 meters, half of which tail amounts), well permits to turn and to keep balance at sharp turns.
The head of the marsupial sharp-toother is armed with powerful jaws and well advanced canines: tips of canines are visible from the closed mouth. Incisors are very sharp, molars are powerful and wide: at lack of alive catch the animal eats carrion, even dried up at the sun. Frequently marsupial sharp-toothers eat up the rests of catch of other large predators. The chewing muscles are well advanced: the animal kills large animals by bite in neck, or inflicts by teeth extensive wounds to its prey and drives it up to exhaustion. Ears of animal are wide, in them there is advansed the circuit of blood vessels: in heat weather they serve for heat emission. Nasal cavity is high, nostrils form a kind of small proboscis – it simultaneously increases olfactory surface and clears inhaled air of dust: at internal edge of nostrils some numbers of the hair playing a part of dust filter grow.
Eyes of animal are directed forward, sight is binocular.
Colouring of body of the marsupial sharp-toother is basically sandy-yellow with faltering pale grey strips on shoulders and head, stomach is lighter, on tail tip there is a hairy brush of long black hair.
Marsupial sharp-toothers are solitary animals meeting each other only for the period of pairing. Also the grown up cubs some time keep near to mother, training in hunting technique. Males at this species are larger and more aggressive than females. Courtship relations of animals remind fight more: the male forces the female to pairing by every possible way, bites its skin on back and forepaws. At adult female’s ears are frequently torn up and bleed: these are traces of similar “grooming” of males. Pairing repeats some times within two - three days, then the male abandons the female and does not accept any participation in posterity rearing. Pregnancy lasts not for long as at all marsupials: about one week; newborn cubs are underdeveloped, more similar to embryons. Usually delivery begins at night, when there is no danger of drying of the cub on the sun. The female lies down in the dug out small hole so that the aperture of maternal passages is little bit higher than an entrance to the marsupium (which opens back), and gives rise up to 5 - 8 cubs. But because in pouch there are only 4 nipples, only those survive who reached to the pouch the first. The aperture of pouch is surrounded with elastic ring muscle which pulls it during movement of animal; therefore cubs do not drop out of pouch during sharp throws at catch chasing. Cubs stay in pouch for about 5 months, thus from four only two, and sometimes only one cum may survive. But its chances of the further survival are rather great: the female furiously protects cubs, attacking even on the largest herbivores if it will seem that cubs are threatened with danger. At the age of six months the cub freely follows mother and can catch small vertebrates, and one year old cub takes part in hunting on equal terms with mother. As a rule, soon after this she can give birth to new litter again. Young animals become sexual mature rather early: one-year-old females continue to grow, but already can rear posterity. Males take part in breeding from the age of two or three years.
Hunting small animals, for example, rabbits, the marsupial sharp-toother tries to creep to them as closely as it is possible under covering of grass and bushes, and then overtakes catch in short throw. Having overtaken with it, it inflicts lateral impact by claws of forepaws, trying to knock down and to wound catch, and then turns around and inflicts to chase a fatal bite. Hnting larger animals, for example, camelopes (antelope-like camels), the marsupial sharp-toother separates the planned chase from herd, and then drives it some hours along the plain, not developing maximal speed. Usually during continuous chasing the prey weakens so, that the predator succeeds to overtake it by one conclusive throw and to seize its throat.
Usually marsupial sharp-toother is active since early morning till midday and in the evening. The animal spends hot daytime in shadow of trees or in rich bushes. If it is a lot of catch, the animal can any time stay in feeding area. Then in bushes or river breakage it digs to itself wide hole where it has a rest in the afternoon and sleeps at night. At lack of catch the animal becomes the nomade and lives in temporary shelters.

Marsupial crab-eater (Cancrivenator dexter)
Order: Dasyuromorphia (Dasyuromorphia)
Family: Predatory marsupials (Dasyuridae)

Habitat: zone of mangrove forests separating Arafura Lake from ocean.
Mangrove forests at the northwest of Meganesia became the house for numerous and various species of animals. There are many species of various mammals among inhabitants of these forests. They can be vegetarians or predators, but one feature unites all of them – they perfectly climb on trees. Some of them eat only the food given by trees, and others feed in swamps, using trees only as a place for life. The strange descendant of marsupial mice belongs to such species – it is mobile and dexterous creature named marsupial crab-eater. The shape the marsupial crab-eater resembles tarsiers (Tarsius) of Holocene epoch, but it strongly differs from them by habit of life.
Marsupial crab-eater is medium-sized mammal. It weighs about 400 grams and it seems rather large because of lengthened paws and long flexible tail. Rear legs of this animal are much longer than front ones, and long tail serves as the balance weight at jumps. Besides the bottom side of tail is naked, and tail is also prehensile. The convergence of marsupial crab-eater and many climbing mammals of New World also had such adaptations ise shown in it. Fingers and toes of marsupial crab-eater are prehensile and mobile. The animal is able to jump and to swarm up trees. Moving down from mangrove trees to the swamp, marsupial crab-eater does not jump off on the ground – it may easily stick in silt and die. It dexterously skips on roots of mangrove trees only on hind legs, and climbs on branches in tree crone with the help of all four paws and tail. Marsupial crab-eater can make long jumps from tree to tree, especially being pursued by predators.
The wool of this animal has reddish-brown colouring with yellow spots forming longitudinal lines on back. Throat, breast, stomach, forepaws and the bottom part of hinder legs are white.
Marsupial crab-eater has large eyes directed forward and providing almost completely binocular sight. Also it has wide rounded ears and long mobile proboscis-like nose. Marsupial crab-eater is an exclusive predator with sharp incisors and multituberculate molars. It eats small animals, searching them on roots of mangrove trees during the outflow time. The basic prey of this animal includes crabs; animal prefers to catch young crabs and crabs of small species. It catches crabs by very original way: in order to seize the crab, the animal overhangs headfirst and keeps by hinder legs and tail for roots of mangrove trees. By free forepaws marsupial crab-eater seizes crab for the bases of claws, and thus does not give it to protect itself, and then it puts to prey fast bite by powerful incisors. This animal eats prey, sitting vertically on tree branch and holding it in forepaws. Marsupial crab-eaters drink rain water, licking it from leaves, or cautiously drinking up the top layer of fresh water from the surface of mangrove swamp channels.
Marsupial crab-eater is a solitary animal meeting congeners only in courtship season. These animals declare rights to territory, uttering loud shrill cries. If two animals meet each other at border of territory, they display force to each other, having seized branch by all paws and shaking it. After rain animals mark borders of the territory with urine.
In the most remote place of the territory each animal builds on tree wum sphere-shaped nest among live branches, bending and plaiting branches with fibres and strong leaves of plants like pandanus (screw palm). Branches continue growing, and the nest becomes strong and imperceptible. In this nest animal spends night, and female leaves the grown up cubs.
The courtship season at marsupial crab-eater proceeds during all year round. Males of this species search for females ready to pairing by smell. Courtship at marsupial crab-eater is rough enough and hard: male interferes to the territory of the female, pursues her and forces to stop for pairing, biting her tail and hips. At this time he utters the special sounds similar to grumble.
After very short pregnancy at the female up to five underdeveloped cubs are born. But in pouch opening forward like at kangaroo, there are only two nipples; therefore only two cubs survive. They develop in pouch for a long time (till about four months). The grown up cubs still some time sit on back of the female, keeping for its wool and having clasped its tail. The female leaves grown up and already heavy cubs in nest and comes back to them for feeding 4 – 5 times a day. At this time cubs gradually start to study climbing and jumping on trees. When they become independent enough and start to accompany with the female during hunting, she has already time to couple and soon gives rise to new cubs.
Marsupial crab-eater becomes sexually mature at the age of one year. Life expectancy of these animals makes 10 – 12 years.

Marsupial potto (Neodasyrus auridae)
Order: Dasyuromorphia (Dasyuromorphia)
Family: Dasyurids (Dasyuridae)

Habitat: mountain forests of Meganesia.

Like other carnivorous marsupial, the quolls had experienced hard times in Holocene epoch: their number decreased greatly due to anthropogenic pressure and competition to introduced placental predators. However, unlike their larger relatives, the thylacine and the Tasmanian Devil, quolls managed to go through anthropogenic pressure, the co-existing with more evolutionally advanced animals, climatic disasters and much more.
However, such “tests” have not gone unnoticed for the quolls: some of their species became extinct, and the descendants of others sometimes began to develop in quite different evolutional directions, acquiring completely different features. Marsupial potto is one of such deviating species.
Like its placental analogue it is a small animal about 26-33 centimeters long, having short tail. This tail is a legacy of the ancestral condition: marsupial potto moves too slowly and does not leap, so it does not really need a tail.
The ancestors of marsupial potto had spotted coloration, but nocturnal lifestyle made the fur of this animal monotonously dark brown with a golden tint. Also it has shorter and broader snout, larger eyes and ears, and longer whiskers. The teeth are small, but strong, able to bite through even a thick bone. Marsupial potto is an active predator that feeds on insects and spiders, slugs and snails, tree frogs and lizards, small mammals and birds – everything that it can catch and kill with a strong bite. Dark fur of this animal makes it hard to see at night when it sneaks up onto its prey – its short legs are poorly adapted for longer leaps or a long chase, but it can sneak up to sleeping birds very cautiously.
Marsupial potto comes down to the ground very rarely – mainly to slake its thirst. But more often this animal finds rosettes of epiphytic plants where water accumulates and so it does not need to go down to the ground at all. Twice a year the females begin to call out to males with barking sounds, indicating the beginning of heat. If two or more males meet near the same female, there will be severe fighting, and sometimes they bite each other. The winner mates with the female and leaves it – the female of this species raises its litter alone. The pouch has only two nipples, but the female gives birth to up to 5 offspring – but only those ones survive, that reach the nipples first. At the age of three months the young begin to leave the pouch and being 8 months old they are independent. By that time the female is ready to breed again. If any female loses its cubs for some reason, it comes into heat much faster.
The life expectancy of marsupial potto is 8-10 years; the sexual maturity comes at two-and-a-half to three years.

Human-caused introducing of placental mammals to Australia had strongly reflected in evolution of local marsupials. Many carnivorous species of marsupials had been exterminated by people or had died out, when people had exterminated large herbivorous marsupials. And small marsupials frequently did not maintain a competition to placental predators. But one group of Australian predatory marsupials had got great advantage from occurrence of placentals in Australia – these ones were small predators, marsupial mice. When epizootias had reduced the number of placental predators occupied Australia, marsupial predators had not missed their chance and had returned in new quality – as clever, furious and easily adapting species. Gradually they had taken a place in new ecosystems of Australia and further in Meganesia.
The descendant of one Holocene species of marsupial mice, tiny (the total body length is no more 10 cm, not including short tail) species of predatory marsupial mammals, had developed the unique habit of life combining predating with original kind of parasitism. It lives in places where many species of large marsupials live, and spends a part of life, parasitizing in their brooding pouch. This animal penetrates into pouches of large marsupial mammals and eats still tiny newborn cub bearing by them. Then adult animal is attached instead of it to the nipple and feeds on milk secreting by the female involuntarily becoming the host of parasite. This animal is named filicide embryotherium.
At embryotherium many infantile features are kept in appearance. The skin of this mammal is covered by thin soft wool and is completely naked in some places. In appearance of animal the sharp sexual dimorphism is expressed. Wool of females is thin and sparse; its color is yellowish-white. Males have richer greyish-yellow wool with cross brownish strips.
Embryotherium, however, spends a significant part of life out of host animal pouch. It is connected mainly with search of sexual partner, settling of young animals and search of host animal by them. Embryotherium has well advanced sensitive eyes and large ears – not living in host pouch animal leads nocturnal habit of life and prefers to hide in various shelters in day time. Its sense of smell is very keen – animal easily distinguishes by smell the female bearing the newborn cub on the background of smells of other part of herd. Paws of embryotherium are strong and supplied with well advanced claws. This animal is rather mobile: embryotherium can swarm up trees, run and jump fast. Its mobility is connected to necessity of search of host animal.
By the appearance embryotherium resembles a mouse. It has rather large head with the short muzzle; muzzle, lateral parts of head and throat are almost hairless. Teeth of animal are short and sharp; only incisors and canines develop. The reason of it is a fact that till the significant part of life animal eats soft food and has no necessity to chew it. Milk-teeth of embryotherium are advanced better, than second ones – it is connected to necessity to lead an active habit of life till the first weeks of independent life, up to the meeting of host animal. Some more interesting adaptations to existence in pouch of host animal are the features of excretory system. Embryotherium produces very dry dung and concentrated urine. Leaving the nipple of host animal, embryotherium puts out back from its pouch, sharply throws outside dung and urine, and then hides again.
Embryotherium is able to hunt and to eat small animals – worms, slugs and soft-bodied insects like cockroaches and young crickets. Usually such diet is characteristic for young individuals. Males spend in pouches of host animals rather small part of life – they grow up, eating milk of the host animal, and at the approach of sexual maturity leave the safe refuge. Adult males search for females by smell and pair with them actively. Sperm keeps viability in sexual ducts of the female till the long time, and it can bring up to three litters after one pairing. It is an adaptation to secretive parasitic habit of life. After pairing the female at which cubs develop, searches for the host animal. It settles in its pouch, kills and eats its cub, sticks to nipple of the host animal, and raises its own posterity in safety and food abundance. In litter of the embryotherium it may be up to 6 – 7 cubs. The pouch of embryotherium looks like two thin and elastic longitudinal plicas surrounding nipples from two sides. Cubs eat parent milk for very long time – it is their only food till about 4 months, and during the entire life they keep ability to digest milk proteins. Young embryotheriums grown up sizable enough, leave host animal’s pouch and lead independent life within several months. Females reach sexual maturity rather early – at the second month of independent life. After pairing embryos in their bodies run to a diapause and do not develop while the female will reach normal physical standard. Free-living males seldom survive over two years, but separate individuals succeeded to find the host animal after rough courtship season, quickly restore forces and can live up to four-year-old age.

The idea about existence of this species was proposed by Simon and Mutant, forum members.

Marsupial bloodsucker (Vampyrotherium nosferatu)
Order: Dasyuromorphia (Dasyuromorphia)
Family: Dasyurids (Dasyuridae)

Habitat: Meganesia, forests, woodlands and bush.

Picture by Alexey Tatarinov

Marsupial mice appeared one of the most successful groups of carnivorous marsupials of Neocene epoch. Large species of predatory marsupial had not sustained a competition with placental carnivors introduced in human epoch. But placentals could not displace marsupials in ecological niches of small predators. The survival of small carnivorous marsupials became a basis of their future success in Neocene. Among Neocene descendants of marsupial mice the true giants, marsupial panthers, had appeared. Other descendants of marsupial mice, embryotheres, had got very strict feeding specialization and had developed the special form of predatoriness which could appear only in the world where large marsupial mammals live. And one more descendant of marsupial mice, marsupial bloodsucker, represents the kind of haematophagous parasite – it is a very unusual phenomenon among vertebrates.
Marsupial bloodsucker is tiny species of mammals: its length is no more than 5 cm (not including tail). Only marsupial shrew – another dwarf species of marsupials – is smaller than this one. In its constitution marsupial bloodsucker differs only a little from other species of marsupial mice – it is mouse-looking mammal with short ears and thin naked tail about 4 cm long. Wool colouring of this little mammal is ash-grey, but head and shoulders are black, and a tip of muzzle is white. Such colouring is disruptive, and it prevents a probable predator to distinguish this mammal in conditions of bad lighting. In case of danger this little mammal hisses threateningly and rushes on predator, putting to it deep wounds with teeth.
Marsupial bloodsucker lives in wood areas of Meganesia, avoiding of semideserts. In savanna it keeps near to reservoirs where bushes and trees grow. In open area this animal has two peaks of daily activity: in early morning and at the beginning of night. It is too hot in savanna or in woodlands in the afternoon and probable predators are more active. And at night, on the contrary, it is also too cold. In tropical forest where day and night temperature difference is less expressed, marsupial bloodsuckers are active in the afternoon. These animals do not have determined territory and lead solitary way of life.
Marsupial bloodsucker eats almost exclusively blood of warm-blooded animals, attacking them while they sleep. It finds potential prey by smell. This little mammal cautiously climbs up in convenient place on their body, precisely determining where the skin is thinner and blood vessels lay close to its surface. For this purpose it is served with a site of naked skin on throat in which the set of receptors is concentrated, and also with receptors on lips. Having found the suitable place marsupial bloodsucker bites through skin of the donor animal and licks off the streaming blood.
Teeth and jaws of marsupial bloodsucker are specialized to this type of feeding. It has broadened and flattened (“bulldog-like”) muzzle with the mobile lips permitting more effective blood sucking. Incisors in upper jaw of animal are compressed from sides and work like blades – they make a vertical cut on skin of prey. The saliva of animal contains anticoagulants (as at American bats Desmodus) and the substances rendering anesthetizing effect.
Marsupials bloodsuckers find each other in forest and savanna with the help of smell. At these animals there are specific glands from which the animal emits a secret having strong characteristic smell as required. During the search of donor animal gland ducts are closed by special sphincter muscles. Also before search of donor animal marsupial bloodsucker carefully licks wool around of gland ducts, hiding its own specific smell.
The courtship period at marsupial bloodsuckers lasts for all year. Male is tinier than the female and approximately 20% lighter. Within one year the female can bring up two litters of cubs. Female has 8 nipples surrounded by ring-like plica of skin forming a brooding pouch, which entrance aperture it is shifted back to the basis of tail. She gives rise simultaneously up to 20 underdeveloped cubs; only ones managed to reach up to nipples can survive. It happens that even four young animals from one litter rarely can survive up to independent condition. They reach sexual maturity at the age of one year; life expectancy of marsupial bloodsucker reaches six years.
These blood eating animals are carriers of filariae – parasitic nematodes. It happens especially frequently in tropical forest. Filariae pass one stage of development in mucous epithelium of mouth of animal and infect donor animals, getting into the blood flowing from the wound made by marsupial bloodsucker.

Forest nargun (Antechinotherium nargun)
Order: Dasyuromorpha (Dasyuromorphia)
Family: Dasyurids (Dasyuridae)

Habitat: all types of forests of the eastern coast of Meganesia.
In the Neocene, there are several animals in Meganesia, that are ecological analogues of the Holocene anteater: crested echidna, which lives in the savannas and woodlands of central and southeastern Meganesia, and the ant-monitor, which lives in the savannas and semi-deserts of southwestern and central Australia. Another specialized insectivorous vertebrate species – forest nargun, a large descendant of the yellow-footed antechinus (Antechinus flavipes) – lives in the forests of the eastern coast of Meganesia. In its appearance, it resembles a cross between numbat and bandicoot, but it is of the size of giant anteater: the largest males weigh up to 60 kg, the largest females do not grow up to 50 kg. The body length is up to 130 cm in the largest males, and 110 cm in the largest females.
It is a heavy-built slow-moving quadruped mammal with massive claws. The animal has an elongated muzzle, a weak lower jaw with reduced incisors and canines, and crushing multi-topped molars. The animal’s muzzle is “armored”: dense keratinized skin protects against insect stings, and the nostrils are able to close. Small eyes are surrounded with dense eyelashes; the animal is short-sighted. To compensate for poor eyesight, the animal has an excellent sense of smell and hearing; large sensitive “rabbit’s” ears help to hear the rustling of crawling insects. The auricles also serve for thermoregulation, radiating the excess heat from the body.
The animal is helped to gather insects by a long sticky tongue that can stick out of its mouth 20 cm far or more. Long pointed claws grow on its front paws, so the forest nargun walks leaning on the back of its hand – in these places “calluses” of dense thick skin had developed. When animal walks, its claws are bent inwards. If attacked, nargun stands on its hind legs and defends itself with sharp blows of its front paws, hissing loudly. Having hooked the aggressor with its claws, the beast clings to it and inflicts deep wounds.
The hind legs are slightly longer than the front legs, so nargun bounces slightly when walking, like bandicoots do. When defending against a large enemy, the beast can spring on it.
The hair on the body and head is short and stiff. The background color is ochre-brown with small black spots scattered throughout the body; the legs are darker, and the belly is light yellow. The animal has a long bushy tail.
Forest nargun feeds on ants, termites, and other small invertebrates living under tree bark or in the wood litter. With its large claws, it digs up anthills, termite mounds and nests of bees, and breaks up rotten stumps in search of insect larvae. The diet may include small vertebrates, bird eggs, as well as berries and small mushrooms. Nargun’s metabolism is very slow, and the beast has incredible resistance to the venom of snakes, spiders, and scorpions. It also enjoys the berries of plants of the nettle family, which are covered with stinging hairs, without harm to its health.
Its lifestyle is nocturnal – during the day, forest nargun sleeps in deep burrows up to 2-3 meters long, in a spacious living chamber. Usually the animal searches for food on the ground; only young individuals whose weight does not exceed 40 kg are able to climb trees. With the exception of the breeding season, forest narguns stay alone, occupying an individual territory of up to 200 hectares. The name “nargun” comes from the name of the mythical stone beast of the Australian aborigines of Kurnai nation from Southeastern Australia (according to their legend, nargun lives in a deep cave, and draws into it unwary travelers who dare to pass by its lair).
The mating season lasts from December to April. At this time, males leave their hunting grounds and search for females, marking trees and the ground with an oily secret produced by a special skin gland on the chest. When they meet each other, the males behave aggressively, hissing and lunging, pushing each other with their sides. Having found a female, the male marks her with his secretions and mates with her repeatedly during the night. The next night, the male searches for another female, and in just one mating season he can fertilize up to a dozen females. Unlike the ancestral species, males do not die at the end of the breeding season, although they lose a lot of weight and become drowsy. The recovery period takes about two months.
The pouch is well developed, opening down and back. The female brings offspring once a year. Tiny (10 mm long), blind and underdeveloped joeys are born 2 weeks after mating. There can be up to 15 joeys in a litter, although the female has only 6 nipples – the cubs that failed to reach the nipple die. The female carries the joeys in its pouch for about 4 months, until they reaches 6-7 cm in size. Then she leaves the offspring in a burrow or in other shelter, and returns to them 1-2 times a night to feed. By the beginning of September, the young beasts begin to leave the burrow for a short time. After a month, the cubs pass to a mixed diet of insects and mother's milk. The young ones stay with their mother for up to 9 months, finally leaving her in December. Maturity comes in the third year of life.
The maximum life expectancy is about 9-10 years, but only particularly large males reach this age. Males usually die faster due to hormonal surges during the mating season, which severely deplete the body. Females live up to the age of 12.

Marsupial Suricate (Phascolomungo nanus)
Order: Dasyuromorphia (Dasyuromorphia)
Family: Dasyurids (Dasyuridae)

Habitat: Tropical bushy savannahs of central Meganesia, arid deserts of Western Meganesia, also around the semi-arid coasts of Eyre Gulf.

Picture by Pavel Volkov

Dasyurid marsupials, predators of various kinds, are remarkable in their short life cycle and usually anti-social behaviour. Individuals of some species may not live longer than a year, but produce as many young as possible. One Neocene species has taken this fecundity to its advantage and has become a social forager, Marsupial Suricate.
This animal is small, no larger than a rat at about 20 centimeters body length, head is wedge shaped with a pointed snout and sharp high-cusped teeth for consuming invertebrates such as beetles and scorpions. Body is low to the ground with slightly longer hind legs than forelegs, but forelegs bear large claws for digging. Tail is short and bushy, with a black tip. This animal is colored a sandy tawny brown, with brindling and striping of darker brown along the spine, paws are white with dark soles, and face has distinctive black “glasses”. Unlike most carnivorous marsupials, Marsupial Suricate is a social animal, living in large groups of over 20 and as much as 35. Social hierarchy dominated by breeding females, as males die soon after mating, breeding depends on constant fights among males in order to court the females.
Individuals in the group forage together during the day, feeding on insects, scorpions, centipedes, bird nestlings and small reptiles, even the young of various venomous snakes. Individuals may work together to harass and kill more formidable prey such as large scorpions or small snakes. As with its namesake, individuals in the group remain alert for threats by predators, climbing bushes or mounds in order to keep sight of potential danger. This is not an individual role and any member of the group performs this action sporadically. Marsupial Suricate is mainly diurnal but does most of its socializing in the late afternoon.
When faced with a predator, the group will mobilize together and seek refuge, unless the combined might of the group may allow them to repel it, in the case of smaller predators such as snakes or birds. The group shelters in a large communal burrow that has several entrances and exits, individuals sleep in a large huddle to maintain body heat, as metabolism is very high. Breeding is constant throughout the year, and males are constantly fighting for the favour of receptive females, unlike a true suricate there is no dominant pair. Several females may bear young at the same time. Males die about a month after mating, and are soon replaced by the new generation.
Females produce up to 15 joeys at a time, and have 13 teats with which to nurse their young. Babies mature in about 5 weeks but do not breed until they are a year old. Males generally do not live longer than a year, dying soon after successfully mating, females may live as long as 5 years and produce many generations of joeys. Vocalisation is a small chirring or a high pitched yarring when alarmed.

Budjagan (Phascolofelis ferox)
Order: Dasyuromorphia (Dasyuromorphia)
Family: Predatory Marsupials (Dasyuridae)

Habitat: Forests of various sorts, Eastern and Northeastern Meganesia.

Picture by Pavel Volkov

A typical trait of evolution is convergence among unrelated forms, and one of the classic examples of this is the Australian marsupials. Here we see analogues of leopards, foxes, weasels, ungulates, moles, hedgehogs etc. During the Neocene this has become even more pronounced in places, with Phalangers converging on primates, and Dasyures converging on many kinds of placental carnivore. Phascogales of the Holocene gave rise to some of the most cat-like of Neocene Dasyures, including the Marsupial Panther, but also the Budjagan, which takes its name from an Aboriginal Australian word meaning feral cat.
Outwardly this animal does indeed resemble a domestic cat, being of a similar size and weight to a typical housecat. Coloration is a greyish fawn color, with dark bands on the tail and hips, turning into spots along the sides, face has a contrasting “mask” of dark and light hairs, feet are dark furred with pink soles, nose is small and pink. The feet are semi-digitigrade, and the limbs are muscular and fairly long, both fore and hind feet have large claws for both climbing trees and capturing prey. Tail is long and bushy, with a white tip. The snout is a good deal shorter than that of a typical dasyure like a quoll, with a broad face and large forward facing eyes, ears are large and pointed, with a coat of fine hair. Canine teeth are long and slender for tearing the throat out of small vertebrate prey, and molars have the carnassial shape for cutting meat, with the rearmost molar being adapted to crush small bones such as the skull of prey. Budjagan has a slightly longer midsection than a placental cat, and in this way slightly resembles a large marten, apart from the short blocky head. Vocalisations range from a hissing growl to a high-pitched yarring squeal. Budjagan is most active at night and does most of its hunting then, but it may also be active occasionally during the day.
This animal is found mainly in forested areas, and is a great climber, commonly hunting birds and possums among the branches. Prey also includes small reptiles and rodents, or even large insects such as moths. It is a solitary animal, only meeting up in order to breed, during the dry season. Females produce a strong musky scent that attracts males from a distance, and more than one male may fight over the right to mate with a single female. Mating is swift and noisy with growling and yarring, but the male does not die after mating, and may produce more than one generation. The pouch is a simple fold on the stomach, and the young will stick out of it when they get larger. After a gestation of 18 days, a litter of up to 10 joeys are born, of which only six may survive the first few weeks. They remain in the pouch for 8 weeks, and in the ninth week will start to cling to their mother’s back to travel, as well as venturing short distances. Joeys mature within a year, and both males and females have a lifespan of up to 15 years. Predators include large birds of prey and any larger kind of predatory reptile; they are usually pugnacious enough to repel other marsupial predators.

Marsupial digger (Pseudotalpa geobia)
Order: Dasyuromorphia (Dasyuromorphia)
Family: False marsupial moles (Pseudonotoryctidae)
Habitat: bush savannas of Meganesia.

Picture by Alexander Smyslov

Marsupials in Australia have shown to the full an opportunity of evolution of separate limited group of animals. Among them in different time ecological analogues of placentary mammals, frequently belonging to different orders, had appeared. Even the marsupial mole lived in Holocene at the territory of Australian deserts – the kind of blind digging marsupials.
In Neocene among marsupials the second time the species having underground habit of life had appeared. It can seem strangely enough, it had evolved due to activity of human for a long time disappeared on Earth. In due time people had introduced rabbits to Australia, and they have successfully gone through cataclysms on border of Holocene and Neocene due to the abilities to adaptation and high fertility. In rabbit holes spreading under ground to many tens of meters and forming ramified systems various species of animals settled. Among them any species of marsupial mice (Antechinus), subsequently adapted to completely underground way of life was. This small predator had to found in rabbit holes practically everything necessary for its life: relative safety and food – numerous insects hiding in holes from day time heat. In holes it was always possible to find larger catch – dead rabbit cubs. Evolution had picked up and had improved this idea and as a result savannas of Neocenic Meganesia were occupied by one more species of digging marsupials – by marsupial digger.
This animal is medium-sized one: length of body is about 20 cm, and height at a shoulder is only about 6 – 8 cm. Body of this small mammal is cylinder-shaped and muscled; it is covered with short velvety brown-colored fur. Paws of marsupial digger are short, on strong forepaws there are three long strong claws of yellowish color (on II, III and IV fingers) with which help the animal carves its burrows. Hinder legs are very short, with narrow feet and four fingers (there is no thumb at the foot). Tail of this animal is short and very thick; it serves for accumulation of fat stock. The layer of fat also is laid on waist of animal.
At the marsupial digger there are short wide head and very strong skull. Bones of skull are thick and also have grown together with each other to solid vault. Eyes and auricles are absolutely not present at it, and nose is covered with corneous scute, as at marsupial mole (Notoryctes). Nasal cavity of animal is strongly expanded, and its internal surface is covered with set of plicas – animal has keen sense of smell. Looking at teeth of marsupial digger everybody will understand that it is furious predator in its weight category: all teeth in its mouth are peaked and cutting; and canines are rather long, even jutting out from mouth.
The marsupial digger lives exclusively under ground and never leaves on surface. If the marsupial mole of Holocene epoch preferred to live in drift sands, the marsupial digger builds constant system of constant holes in dense ground, in which it waits for catch – every possible small animals. These small mammals are very strong, and are able to kill animal larger than itself. Metabolism at marsupial digger is rather intensive: for day it eats quantity of food only twice less, than it weighs itself. Having found a plenty of food, the animal eats it all and quickly accumulates fat in back part of body and tail. The full digger becomes inactive to any time. It creeps to the hole, closes an entrance by cover of friable ground and vegetative rests, and sleeps. After the food will be digested, it wakes up and begins to hunt again.
The hole of marsupial digger includes main chamber located at the depth about 2 meters under ground, additional chamber which incorporates with main one by unique vertical corridor, and system of radial burrows spreading from the additional chamber to sides at the depth about meter. On the ground surface it is possible to heaps of ground pulled outside by this animal. The marsupial digger throws out ground through an inclined course, instead of vertical shaft, as moles do.

Burrow systems of different animals of this species never incorporate directly with each other: marsupial diggers are soliyary animals. But it yet does not mean, that this animal avoids other “colleagues” in underground life: whenever possible this animal builds joint systems of holes with rabbits. Some burrow systems of marsupial diggers frequently adjoin from edges to one settlement of rabbits. Obviously, rabbits are not in delight from such neighbourhood: the marsupial digger makes it having especially gastronomic interests – it can attack rabbit cubs, and at times attempts even healthy adult rabbit if it will manage to cut off way to escape to prey. Besides having attached the dwelling to hole of rabbits, the animal saves forces at burrowing of own holes, chasing every possible inhabitant of rabbit holes. More often rodents – mice and rats appear on its “lunch table”. Sometimes even other small predators - marsupial hermins (Mustelogale dolichocranus) become its prey, getting for hunting in holes of rabbits. Obviously, at an attack against such rather dangerous animals the horn scute on muzzle rescues the marsupial digger against wounds.
During breeding season males leave holes and wander in underground burrows searching for females. They are extremely aggressive relatively to each other and if two males will meet in hole, one of them can kill and to have eaten another one.
At these animals constant pairs have not formed, and the destiny of posterity is completely indifferent to the male. At any opportunity male even can eat young animals if will to find a hole with cubs. The female gives rise only to three – four underdeveloped cubs. They creep in pouch (opening back) and grow in it about one month. After that the female leaves them in hole, and regularly comes to feed. For one year the female has about three packs.
Three-month aged cubs already can freely move in underground holes. They leave territory of the female and live independently. Within the first months of life repugnatorial glands at them are not advanced, therefore their presence can remain unnoticed by adult animals of this species. But up to the period of puberty (at the age of about seven months) at young animals the smell appears, and aggression sharply grows. The marsupial digger lives seldomly more than four years.

Marsupial spiketail (Spinurotherium leucospinus)
Order: Dasyuromorphia (Dasyuromorphia)
Family: Spike-tailed marsupial rats (Spinurotheriidae)

Habitat: bushy savannas of Meganesia.

Picture by Alexander Smyslov

In Neocene climatic conditions in Australia/Meganesia became more favorable for life. Water had come to central areas of this island continent, having transformed deserts to savanna with circuit of shallow-water rivers and lakes. In such favorable conditions many new species of animals have appeared on continent.
The fauna of Meganesia of Neocene epoch represents fantastical combination of descendants of native marsupial mammals and introduced by people placentary ones. Epizooties of rabies and plague of carnivores have reduced chances of survival of introduced placentary predators to zero, but the competition to them had perfected features of adaptation at local marsupial Carnivores, and had permited to few survived ones to take place at top of food pyramid. Among large-sized herbivores it is possible to meet not only graceful and harmonous descendants of camels found due to the people new native land in Meganesia, but massive marsupial animals too. And among small and medium-sized animals marsupials successfully compete to rabbits and rodents introduced to this continent.
Among dense grass of Meganesian savanna it is possible to see strange object: something similar to white flower, sticking up on hairy stalk. But, when this object starts to move among grass stalks, it becomes clearly seening, that it is not a plant but any animal. From time to time the owner of this “flower” rears on hinder legs, and it can be seen more detailly. It is a cat-sized animal covered with short wool. At it there are long flexible nose surrounded with thin wiskers, round eyes and ears similar to rabbit’s ones. Well advanced claws are appreciable on strong paws of this animal. And the thing looking like certain fantastic “flower” actually is very long tail. At the tip of tail hairs are modified to white-colored needles with black bases forming hairy brush. For such appearance of this structure the animal had received the name “spiketail”. It has habit to lift from time to time tail vertically upwards: this way spiketail communicates with neighbours at long distance. A certain species of Australian marsupial mice had become an ancestor of the spiketail.
Colouring of animal is rather motley: the body is covered with brown wool with dim black speckles, the mouth is led round by thin strip of white wool. On the back of marsupial spiketail there are some alternating black and white cross strips. All tail is black, and white needles are brightly appreciable on its background. Being attacked by predator, spiketail warns it that it is armed, curving back like a cat, lifting up tail, and shrilly squealing. If it does not stop predator, the spiketail protects itself against it by impacts of tail. In the basis of each spike there is a muscle attached by one end to backbone. With the help of such muscles the spiketail can press spikes to each other, forming “beater” or to spread them widely in sides, forming true weapon which impact can be rather painful. Defending itself against predator, marsupial spiketail turns around on hinder legs, keeping to aggressor by side and swinging by tail extensively.
In mouth of spiketail it is possible to see both sharp incisors and canines, and wide knobby molars. The marsupial spiketail has a little deviated from diet of ancestors: it is omnivorous (marsupial mice are predators), and the most part of its diet consists of plants. The animal is able to dig out roots from ground, dexterously swarms up bushes and low trees in searches of fruits, chews unripe seeds of grasses. But it also likes to diversify the diet with food of animal origin. On trees and in bush marsupial spiketail searches for small reptiles, large insects and bird’s nests. In the ground except for roots spiketail willingly finds and swallows worm or larva of any insect. By smell it finds the rests of predator meal, and with pleasure gnaws bones and cartilages.
These animals are solitaries, but they support visual contact to neighbours, from time to time rising on hinder legs and looking around. They usually avoid close meetings, preferring to leave an urine mark on objects allocated among savanna – trunks of trees, termitaries and stones. Unique exception is a time of breeding season. At this time marsupial spiketails gather to small groups – approximately fifty-fifty females and males. Males compete with each other for females, establishing hierarchy in short duels. During such tournaments they beat each other by tail, but in this case needles are densely compressed and do not cause wounds to the opponent. After pairing the male loses interest to the female and starts to look after for next one. Thus it jumps after chosen female on hinder legs, uttering keen chirp and snort. Each female couples with several males, therefore paternity at these animals is difficult to establish. Sometimes in one pack cubs at once from two males can appear.
After short pregnancy the female gives rise to about ten tiny underdeveloped cubs. But the chance to survive is not at all of them: at the female there are only six nipples. The pouch at this animal is presented by two longitudinal plicas of skin, surrounding nipples from two sides. This skin is elastic, therefore cubs are not threatened with danger to drop out of it. They develop in pouch about three months, and to this time from six cubs only three or four ones survive. Grown up cubs move on back of mother, and it drags them on herself one month more. At this time on tails of young animals needles start to grow. Gradually cubs pass from milk to adult diet, and start to feed near mother independently, at the same time training at it to ways of food getting. Half-year old cub already becomes completely independent. The young female can bear posterity first time already at one-year-old age.

Stinktail (Malodorocauda catta)
Order: Dasyuromorphia (Dasyuromorphia)
Family: Spike-tailed marsupial rats (Spinurotheriidae)

Habitat: Bushy savannas and light forests of central Meganesia, forested areas of south eastern Meganesia.

During the Holocene, the role of small and mid-sized omnivores in Australia belonged to two kinds of marsupial, Bandicoots and Potoroos. This situation has changed in the Neocene, previous predation pressures from feral carnivores during the age of man eradicated the bandicoots, and potoroos diversified into different forms in the early Neocene, proboscis kangaroos, and also various small carnivores, though some forms remain close to the ancestral shape and lifestyle. Additional to this came the event of some kinds of marsupial rat becoming more equable to consuming plant matter, thus producing omnivores. One example is the family of spike-tailed marsupial rats.
This family is exemplified by forms which bear a brush of sharp quills at the end of the tail, but more primitive members of this family also exist, such as the Stinktail. These forms have only bushy hairy tails, but still use them for defence, chemical defense. The Stinktail is about the size of small housecat but differs by large noticeable claws on the forepaws, and pointed snout, the tail is long and bushy, colored with alternating dark and white bands. This marsupial produces a powerful chemical from its anal glands, which smells very noxious and strong; it habitually grooms and rubs this secretion into the fur of its hindquarters and tail. When faced with a predator, the tail is brought upward and forward, batted and fanned at the opponent, subjecting it to the unbearable smell. If the predator is not repelled by this, the Stinktail will squirt glandular secretions directly at it, much like a skunk. The body of the animal is a mid-toned greyish brown, with darker brindle beginning on the hips and becoming full dark bands on the tail. Paws are lighter, bearing white fur and pink soles, and the face has a dark “mask”.
This creature, as with the Marsupial Spiketail, feeds on both plant and animal matter, but Stinktail is predisposed to feed on softer food, and does not consume seeds or stems. Vegetable food includes roots, fungus, fallen fruit, and buds of new growth, various insects, larva and small vertebrates are eagerly eaten, as well as the eggs of birds or lizards. Stinktail has large foreclaws, resembling bandicoot a little, and will search for food by digging, as well as climbing low trees or searching in the undergrowth. Vocalisations consist of a throaty hiss when annoyed or a high pitched growl when establishing dominance. This animal is crepuscular, being most active during dawn and early morning, and again during late afternoon and dusk.
These animals live in loose family groups of up to 6, and will forage over a large area during the day. The banded tail is usually carried aloft to maintain contact in the group, and individuals may rear on hind legs to keep sight of others. At the sign of a predator, more than one individual may undertake the threatening display of chemically armed tails, driving it away. In the breeding season, which falls to the dry season, family groups merge with each other in some areas, and males will display and posture in an attempt to court females. Males produce a special kind of sweeter scent during the mating season, and compete by vigorously shaking their tails and stamping their feet. Females will mate with numerous suitable males, and give birth to a litter of 12 joeys, only 6 of which usually survive, as the folded pouch only contains six teats. After about 3 months, the young move from the pouch to cling to the back and tail of the mother instead, by six months they are fully weaned and become independent. Young females become fertile at one year. Lifespan is short and generally does not surpass 5 years, and with steady breeding, numbers within the group stay constant.
Relative in the rainforests of northern Meganesia is the Spicetail (Malodorocauda capsaicis). This animal is slightly smaller, only as heavy as a rabbit, and is a dark reddish color, tail is banded chocolate brown and white. This animal differs in its chemical defence; its anal secretions contain a poison that is extremely bad tasting to predators, overly spicy and painful. The animal rubs this secretion all over itself including its tail, and will lick up the secretion in order to coat its teeth. When faced by a predator, it will fan and direct the smell with its tail, but if seized in the opponent’s mouth it is quickly dropped because of the unbearable taste, Spicetail may also administer bites which allow the poison to penetrate into the predator’s blood and cause extreme pain. The diet of this marsupial is mostly similar to its central relative, though its lifespan is slightly shorter. Also, Spicetail forms smaller family groups that range widely apart from each other during the day.

This species of mammals was discovered by Timothy Donald Morris, Adelaide, Australia.

Erucotherium, caterpillar beast (Erucotherium quasiapodus)
Order: Dasyuromorphia (Dasyuromorphia)
Family: Erucotheres (Erucotheriidae)

Habitat: tropical forests of Meganesia, leaf litter.

Picture by Alexander Smyslov

In Neocene restoration of tropical forests stimulated intensive evolution of forest inhabitants and occurrence among them of specialized forms occupying strict ecological niche. One species of mammals living in forests of Meganesia reached an extreme degree of specialization to its way of life. This creature is the distant relative of marsupial mice passed to burrowing habit of life. Its specialization had gone very far; the result of it is a significant reduction of some parts of body. The name of animal means “almost legless caterpillar beast”. It lives in friable leaf litter of Meganesian forests, not being dug deeply in firm ground. In the body shape it has convergent similarity to wedgehead (Herpethotalpa caeca), digging lizard of skink family living in the same places. The body of erucotherium is about 40 cm long at the maximal thickness up to 7 cm. It is cylindrical, truncated on the back end and wedge-shaped from head end. Wool is short, dense and velvety, of grey, brown or reddish color. On head there is a flat corneous plate of yellowish color is advanced; it serves for protection of skin at digging.
Forepaws of erucotherium are strongly reduced. Bones are very short; ulna is reduced and radius is thickened. Hand bones fuse and lose mobility. Only humeral and wrist joints keep partial mobility. From outside from forward limbs two large claws (3-rd and 4-th fingers) located on small lumps protrude – it is an only seen part of forepaws. Claws serve for fastening in the ground and for pushes. Hinder legs are less reduced in comparison to front ones and keep the limited mobility. Two-toed foot with thin and mobile 2-nd and 3-rd toes and normally advanced ankle joint is visible outside. The role of these toes in life of erucotherium is great: they serve for clearing of pouch at females and for keeping of the female during the pairing at males. Strong flattened tail with the wide basis helps to push forward in the ground. The tip of tail is dulled and gristly – it serves as a support at burrowing in the ground. Tail vertebrae have wide and powerful lateral outgrowths.
The chest of animal is motionless, ribs strongly fuse to backbone. The animal breathes exclusively with the help of diaphragm movements. The lumbar part of backbone is long and very flexible: animal can easily bite its own heel.
Despite of deep specialization to underground habit of life erucotherium is not helpless if it should leave a usual inhabitancy. In case of need it is able to swim perfectly, waving the whole body as if a dolphin. With the help of sensitive bristles on muzzle it perceives the waves reflected from subjects, and can be guided in water and bypass large obstacles at least partly.
Eyes of erucotherium are strongly reduced and hidden under skin. The skull of animal is strong and thicken; it serves for tunnel burrowing. It is flattened and has advanced cross crests for an attachment of the muscles raising head up. External ears are lack; the acoustic duct represents a small aperture. This animal perceives good the sounds getting in ear from the ground through bones of lower jaw. The similar mechanism of sound perception is characteristic for cetaceans, but in this case it was developed independently. This animal hears badly the sounds spreading in air. Erucotheres communicate to each other with the help of the odorous labels left in thickness of leaf layer.
This mammal eats any animals living in leaf litter. In order to get food erucotherium developed long tongue which can be extended forward for length of head. Edges of tongue are covered with corneous combs, and its basis had shifted far back and is attached to sternum. Tongue serves for digging and capture of worms, insects and their larvae, and also helps to clean wool. Due to flexible backbone animal can lick wool on all parts of body.
Erucotherium is reliably protected from enemies. In the basis of tail it has a pair of glands secreting badly smelling oily liquid. Defending against enemies, this animal can bite strongly. It has pointed teeth adapted to feeding on insects. Besides the saliva of erucotherium is toxic for small animals and in large predators it causes long weakness and pain if gets in open wounds.
Seasonal prevalence in breeding of this species is not present. Male finds the female ready to breeding by smell, pairs with her keeping her by teeth and by hinder legs, and leaves female right after pairings. Pregnancy is short as at all marsupials – not longer than one week. The brooding pouch having two nipples is opened back and before birth of cubs the female clears it by toes. The female raises only two cubs two times per one year. During the cub birth she turns on back and cubs have an opportunity to creep into the pouch. Up to five cubs are born simultaneously, but only ones managed to reach nipples can survive. They develop in pouch till two months and then the female cares of them till about one month, feeding them up on caught insects. Young animals reach sexual maturity at the age of 8 – 9 months. Life expectancy does not exceed 8 years.

Gliding false quoll (Carnopetaurus carnifex)
Order: Diprotodontia (Diprotodontia)
Family: Petauridae (Petauridae)

Habitat: Northern Meganesia, tropical forests in mountains and valleys.
Australia was a continent with a very unusual destiny, fauna and flora, which were influenced by the long-term isolation of the continent in the Mesozoic and Cenozoic. Among the local mammals, ecological analogues of many placental mammals of other continents arose. The fauna of predators was much poorer: its main representatives were marsupial “mice” and “native cats”.
This situation has changed somewhat in Neocene. Predatory marsupials of Dasyuridae family still exist in the fauna of Meganesia, but carnivorous descendants of other families of marsupials, including wrist-winged gliders, appeared next to them. Gliding false quoll is one of these mammals.
Outwardly, this animal resembles quolls, spotted “native cats” of Holocene Australia, reaching a length of 52-65 cm, not counting the long tail. The wool coloration of this animal has no spots – it is monotonously gray or brownish. Adult animals have a darker (even black) mask on their head, which appears in mature animals. Gliding membrane (patagium) inherited from the ancestors of this animal has not shrunk, but partially reduced, so the gliding false quoll is unable to make long gliding jumps. This gliding membrane helps the animal to make fast, maneuverable rushes in pursuit of prey, or to escape from enemies by jumping from one tree to another.
The partial reduction of the area of the gliding membrane is compensated by well-developed strong limbs. Gliding false quoll is good at running and jumping along branches, and climbs vertical surfaces perfectly. This animal almost does not descend to the ground, since its paws and claws are adapted only for climbing trees. Gliding false quoll is a very strong animal for its size, armed with sharp cutting teeth and strong claws. On the ground, this animal feels insecure, moves with clumsy jumps and tries to climb a tree if possible.
Unlike its ancestors, gliding false quoll almost never eats vegetable food – only occasionally it can eat soft ripe fruits with small seeds. The main food of this species is meat of various mammals and birds, as well as invertebrates. The animal drinks water from the rosettes of epiphytic plants and from tree hollows. The main enemies of this species are local birds of prey and tree snakes, in particular pythons.
The mating season of gliding false quoll is extended throughout the year. These animals are monogamous and often form permanent pairs, which is quite rare phenomenon among the marsupials. Both animals jointly guard the feeding area and drive away competitors. The female gives birth to one cub, less often two, and carries the offspring in its brooding pouch for several weeks. Even after a young animal leaves its mother’s pouch, it still stays with its parents for several months until it becomes completely independent.
The average life expectancy of gliding false quoll is 16-20 years.

Marsupial sloth (Bradyphalanger scandens)
Order: Diprotodontia (Diprotodontia)
Family: Phalangers, or Climbing marsupials (Phalangeridae)

Habitat: tropical woods of Northern Meganesia.

Picture by Alexander Smyslov

In Neocene Australia moving to the north has collided against New Guinea Island. As a result in northern area of continent young mountains have started to increase. This area is in the zone of equatorial climate, and mountain covered by rainforest giving shelters and food to various live creatures. As well as in other parts of the world, life in Meganesian rainforests is concentrated in forest canopy at height 20 - 30 meters above the ground. Many original live creatures, descendants of Holocene inhabitants of this region, live here. One of them is the original herbivorous representative of marsupials – marsupial sloth, the descendant of cuscuses (Phalanger).
Similarly to South-American “colleague” of Holocene epoch, marsupial sloth is the inactive herbivorous animal slowly moving in tree crones, suspending on them from below with the help of hooked claws. This animal weighs about 15 kgs; length of its body is about half meter. However, as against the “true” sloths of South America, the Australian marsupial sloth has also long prehensile tail, by the size exceeding body length. The bottom side of this tail is covered with naked skin with set of cross combs (similar to papillar patterns on hands of primates) – it raises durability of capture of support. Working as the “fifth paw”, tail helps this animal to keep on branches. But basic organs of movement are unusual paws of the marsupial sloth.
Forepaws of this animal are similar to monkey’s ones - the thumb opposes to fingers. But on hinder legs from one side the thumb and joined together second and third toes, and from other side fourth and fifth toes are opposed against each other. Back legs of the marsupial sloth are powerful “pincers” by which it grips branches when it takes to itself food by forepaws. Backbone and neck of the marsupial sloth are very flexible: hanging a back downwards, the animal easily can bend a half-revolution, touching by forepaws the bottom branch of tree.
Head of the marsupial sloth is rather flat, short and wide: at it chewing muscles are strongly advanced. Molars of animal are wide and knobby – leaves of trees and firm seeds which this mammal cracks with loud crunch make significant part of its diet. The marsupial sloth willingly adds food of animal origin to its diet: eggs and nestlings of birds, and also large insects and snails.
The marsupial sloth is colored according to the habit of life: because more than half of time it spends hanging under branches, its stomach is darker, than back is. On the back of animal fur is gray-brown with numerous narrow faltering cross strips – it is an excellent imitation of tree bark. On stomach wool is monocoloured, dark-brown. Hands and feet of animal are naked, covered with rosy-gray skin. Around of big orange-brown eyes there are circles of yellowish wool, tip of muzzle is of the same color. Male and female do not differ in colouring; the male is simply a little larger.
At this animal color binocular sight is advanced, there is sharp sense of smell, and the hearing is a little bit dulled. Nasal cavity of the marsupial sloth is short and wide, and ears are almost latent in fur. By the “intellectual development” this animal continues “traditions” of marsupials: brain cavity at it is small. But at its habit of life the special ingenuity is practically not needed.
Marsupials sloths are sluggish solitary animals. They are practically omnivorous and do not depend on any limited fodder resource, therefore they tolerantly concern to presence of each other and have no protected territories. Only the female bearing posterity in pouch becomes a little more aggressive to neighbours.
Pairing and birth of cubs at marsupial sloths occurs practically in any season. The female ready to pairing, during movement marks branches and leaves by the smell: repugnatorial glands at it are in axillary area, and it simply drags a branch between paw and side, having griped it. The male finds the female using these marks; then he couples to her without any rituals, and marks wool of the female by his smell. Such feature of behaviour is characteristic for some Holocene species of cuscuses.
Pregnancy lasts not a long time, and after 8 - 9 days tiny underdeveloped cubs are born. Usually up to 10 cubs are born, but at the female there are only six nipples, therefore some newborn marsupials sloths at once are doomed for death. Cubs independently get into pouch opening back, and start to suck milk and to grow. Approximately at the age of two months they can leave mother’s pouch and remain on its body, clinging for its paws. Usually up to this moment only three or four cubs from all survive, and only two or three cubs from litter can become independent completely. At the age of four months youngsters already depend on mother a little, and to the age of five months they become completely independent. At this time the female already carries a new pack in pouch. For one year it can give birth up to three packs of cubs.
Young marsupial sloths become sexual mature at one-year-old age though active growth proceeds at them till two years. Life expectancy of these animals is no more than 8 – 9 years.

Drummer cuscus (Onychowirlda tympanista)
Order: Diprotodontia (Diprotodontia)
Family: Phalangers, or Climbing marsupials (Phalangeridae)

Habitat: plain rainforests and mountain fog woods in Northern Meganesia.
Neocene is the epoch of the occurrence of extensive large forests in Northern Meganesia, and the development of rich fauna of tree-climbing animals. In forest canopy, at height of several tens meters above the ground, various mammals live: rodents, chiropters and marsupials. For similar ecosystems the combination of two factors is typical: on the one hand, the abundance of kinds of food, but on the other hand, rather rigid competition. Therefore in such ecosystems very much specialized species frequently evolve.
In the evening and at night in forest canopy frequently it is possible to hear rolling knock on tree, similar a little bit to drumming which a beak of woodpecker beats out. Woodpeckers do not live in Meganesia, therefore instead of them absolutely other animals hunt wood-boring insects. One of these creatures is rather large (cat-sized) species of cuscuses. This creature is vaguely similar to lemur aye-aye (Daubentonia), dwelt on Madagascar in Holocene epoch. But instead of thin sensitive middle fingers thumbs armed with thick massive claw are strongly advanced on forepaws of this cuscus. On other four fingers there are very sensitive subungiuses covered with thin skin. Searching for insects, this cuscus “drums” on bark and wood by thumb claws and catches vibrations of wood by subungiuses of other fingers. Because of this feature the animal has received the name drummer cuscus. Most likely, it is the descendant of fox brush-tailed cuscus (Trichosurus vulpecula), one of few cuscuses had received advantage from the neighbourhood with people in Holocene epoch.
This marsupial is fine tree-climber, spending all life in crones of trees and never going down to the ground. All paws of this animal are prehensile, and the long fluffy tail serves for maintenance of balance. The short velvety fur of the drummer cuscus is colored grayish-beige color with marble pattern of cross strips. It provides fine masking for animal swarming up on bark. Drummer cuscus is too massive to jump from branch to branch similarly to marsupial lemurs, cats or primates. But its paws differ in great strength of seize – this animal can hang freely on one paw, and during the combat with small predator cuscus can simply strangle it. Even dead animals of this species seize branches so strong, that they fall on the ground already semi-decomposed.
At this marsupial there is the head with short wide muzzle and large sensitive ears. Eyes of drummer cuscus are large and yellow, with strong shine characteristic for nocturnal animals.
Distinctive feature of this animal is strongly advanced incisors similar to incisors of rodents, and very strong chewing muscles. This is the adaptation for feeding on insects hidden in thickness of wood. “Percussing” wood by claws, animal listens to the tonality of sound, and feels by fingers changes in character of vibration of wood. By these attributes drummer cuscus defines presence and direction of tonnels made by larvae of insects in wood. Having found out a tunnel pierced by beetle larva or other insect, cuscus opens it by several strong bites.
Other feature of this mammal is very long tongue which can extend from a mouth to ten centimeters. The basis of tongue is strongly shifted back - almost to breast bone. On the tip of tongue the cross comb of corneous hooks, which can be shifted relatively to each other a little, grows. Having opened dwelling of insect, drummer cuscus pushes tongue in hole, and hooks larva on by these hooks.
This animal goes to feeding in the evening and at night, and in dawn time it hides in deep tree-trunk hollows or covered bird nests. Drummer cuscus dozes hottest time of day, having covered sensitive eyes by ears and paws. At this time it is enough vulnerable. Day time sleep of animal is sensitive, and, being disturbed, drummer cuscus makes sharp movements by claws of forepaws, trying to strike the enemy by them.
Drummer cuscuses are strictly solitary animals; only the female and her posterity can keep together till some time. At night each animal from time to time reminds to neighbours of its existence, uttering shrill high-frequency squeak. Male searches for female ready to pairing, using such sound and special odorous labels.
The male of drummer cuscus is approximately a quarter lighter, than the female is; besides at him there is darker pattern on skin. Seasonal prevalence in breeding at this animal is not expressed, and at any time of year in wood there are females having posterity at various stages of development. Per one year the female of this species gives rise two times to up to ten cubs, which leave the brooding pouch at the 3-rd month of life. To this moment from pack only two or three cubs survives. Till about one month they move in wood on back of mother, and then start to lead independent life. Young animals reach the sexual maturity at the second year of life. General life expectancy of animals of this species does not exceed 10 years.

The idea about existence of this animal was stated by Simon, the forum member.

Badger possum (Australofossor crassicaudatus)
Order: Diprotodontia (Diprotodontia)
Family: Phalangerids (Phalangeridae)

Habitat: tropical forests in the north and east of Meganesia.
Possums represent one of the most successful groups of marsupials of Neocene Meganesia, inferior only to kangaroos and dasyurids. Their species diversity has been seriously affected by hunting and habitat destruction by humans. But after the disappearance of humans, they managed to restore species diversity and, in the course of evolution, gave rise to new life forms. In the forests of Meganesia, marsupial lemurs live in trees, and their ecological antipode, badger possum, a ground-dwellin animal descended from ground cuscus (Phalanger gymnotis), is found in the undergrowth. Evolved in the north of Meganesia, it quickly spread across the tropical forests of the continent.
It is a relatively large animal, with a body length of up to 70 cm; its weight is about 14 kg. Its fur is relatively sparse; the tail is hairless and covered with pinkish skin. Fat is stocked in the tail, so in well-fed individuals it is thick, and this is a sign of good health. The sides and hind limbs are light brown with a yellowish or grayish tinge; forelimbs, head and back are dark. On the head and neck, the general dark coloration contrasts with the white areas on the throat and above the eyes. Ears are rounded and small; eyes are small. Muzzle is short and rounded. Front paws are very strong, equipped with two thick claws.
This species lives in pairs that share a common burrow. The length of the burrow reaches 4-5 meters; it is dug under the roots of trees and has several turns. Badger possum feeds on various invertebrates (worms, insects), small mammals, birds, frogs, lizards, eggs and fruits. It mainly hunts on the ground, grubbing in the wood litter and breaking rotten tree trunks and stumps, but occasionally climbs trees also. These animals are active during the daytime. It spends the night in burrows, which are usually used for many years, sometimes even by several generations of animals. Badger possum is aggressive towards strangers, expelling them from its territory with growls and bites. Animals of similar size (up to a meter long) are attacked by this possum.
Mating takes place in October and November. Courtship in young individuals represents a simple chase for a female and displaying of the force, during which the male presses the female against the ground and slightly bites her skin. When two males meet, a struggle begins – both animals wrap their paws around each other and try to press the opponent to the ground, growling and hissing at the same time. In the established breeding couple, male tries to help the female to repair and expand the living chamber. The gestation period lasts 13 days. The female gives birth to from one to three (usually two) underdeveloped joeys, according to the number of her nipples. They live with their mother for up to 9 months – first in her brooding pouch, then they stay in the burrow, and only since the age of 6 months they go out to search for food with their parents. Grown-up badger possums leave the vicinity of their parent burrow and search for a new territory to settle there. Sometimes a young animal can hound an old one out of its hole, but it usually digs its own hole. Puberty occurs at the age of 2 years, and life expectancy is about 25 years. Animal’s natural enemies are aella eagle, large snakes and monitor lizards.

Woolly False Cuscus (Enanticuscus novaezealandiae)
Order: Two-front Teeth (Diprotodontia)
Family: Possums and Cuscus (Phalangeridae)

Habitat: cool mountain forests and temperate lowland forests of the South Island of New Zealand, forest canopy.

Picture by Pavel Volkov

Though the introduction of the Brushtail Possum (Trichosurus vulpecula) into New Zealand, served to catalyse an adaptive radiation of unusual forms, including predators and giant ones, some forms came to more closely resemble their Meganesian cousins.
The Woolly False Cuscus is a large arboreal possum found in the temperate woods and cool mountain forests of the South Island. Body length not including tail may be up to 60 centimetres, and the tail is the same length again, weight does not exceed 7 kilograms. Build and particulars of the body resemble both its ancestor, and the Cuscus of New Guineas Holocene, a bulky climber with powerful limbs, gripping hands and feet, and a large rounded head with big circular eyes. Its coat is dense and woolly, even more so than its ancestor, and very soft to the pouch, tail is muscular and prehensile, and covered in a coat of mid-length dense fur, tail underside is naked. Fur is coloured a pale grey, which darkens to almost black on the rump, shoulders and back are covered in irregular black and light-grey patches. The skin of the face is covered in a fine coat of dark fur, appearing like a mask around the eyes and nose. Eyelids, nose, soles of the feet and underside of tail are naked and dark pink.
Diet consists of soft leaves, fungus, fruit and seeds, large insects and caterpillars are also eaten, this animal will eagerly consume bird eggs and nestlings, in lowland woods the nuts of conifer cones are often eaten. This animal is an adept climber, spending most of its time in the branches of trees, but it may also occasionally seek food on the ground, such as fallen fruit or mushrooms. False Cuscus is mostly nocturnal, foraging and feeding at night, by day it sleeps I large tree holes or in the fork of a large tree limb. It is generally shy, and will flee at the first sign of an intruder or predator, if cornered it can bite or scratch fiercely. Generally solitary, males mark their territory with musky secretions, and by chewing the ends of branches, confrontations usually occur when males meet, and will involve grunting and snarling loudly.
Mating occurs year round, but is most frequent between October and February, in the warmer months. Courting takes place on tree limbs, and the male will consort with the female for up to two and a half weeks. Mating is promiscuous, and may take place with multiple partners within the year. Gestation is up to 13 days; two small pink joeys crawl into the pouch and develop there for as long as long as 7 months, growing and suckling. Lifespan is up to 12 years, sexual maturity is reached at 1 year. Predators most often are the eagle kea, on the ground it may fall prey to the Ruacapangi bird or Marsupial Pardus, it is usually too large to be targeted by hawks.

Banjora, False Koala (Pseudophascolarctos rotundus)
Order: Two Fore Teeth (Diprotodontia)
Family: Phalangers and cuscus (Phalangeridae), Subfamily Pseudophascolarctidae (monotypic)

Habitat: Jarrah forests of the southeast of Meganesia, temperate forests of eastern Meganesia, exclusively where eucalyptus trees grow.
Specialized kinds of animal often suffer the worst effects of mass extinction, and thus the Koala suffered extinctions at the hands of man’s forest clearing and disturbance in Australia during the Late Holocene. But the niche of a slow-clambering exclusive leaf-eater is one that has often been repeated by evolution, and so it happens again with the False Koala, or Banjora (coming from an Aboriginal boy’s name meaning Koala). The ancestor of this species was the rather generalist Brushtail Possum (Trichosurus vulpecula), as we often see, specialists commonly evolve from more generalized ancestors.
Outwardly it is a stocky round animal with a large hindquarters and a stubby tail, this tail serves some purpose of fat storage but is otherwise useless. An adult male can weigh up to 9 kilograms, with a body length of 78 centimetres, females are slightly shorter but weigh about the same. Its head is large and supplied with heavy chewing muscles, the snout is short and arched. They feed entirely on the leaves of various kinds of eucalyptus tree. The original Koala was restricted to consuming only a few species, but the Banjora can gain sustenance from most kinds of eucalypt. Its nose is dark in color but resembles that of a possum more so than a true koala, eyes are small and brown, vision is poor but hearing and smell are acute. Ears are slightly enlarged but are pointed and do not resemble those of a koala, having a thin coat of white hairs. Colour and softness of the fur is intermediate between that of a koala and that of a Brushtail Possum, thick, fluffy and colored brownish grey, but the rear and face are darker, almost black. Hands and feet are both built for gripping branches, and bear very large curved claws, both hands and feet bear prehensile thumbs but that of the foot does not bear a claw, syndactyly of the foot is not overly pronounced.
Banjora are able to clamber about in the treetops and even make short leaps between trees, but are more adept on the ground than a true koala, often crossing larger distances between trees on foot. These marsupials are diurnal but are most active in the afternoon. Predators include various carnivorous climbing marsupials, some larger kinds of monitor lizard, and raptorial predatory birds such as eagles, hawks and owls. Banjora may defend themselves by biting hard or by scratching with their large fore claws. Vocalisations vary from a guttural hiss or chatter when annoyed, to a loud scream uttered by the male during breeding season.
Banjora are generally solitary, but breeding is sporadic all year long, peaking in the spring, from September to November. Reproduction is slower than their ancestor, and usually only one young is born. As with all marsupials this baby is born poorly developed, and matures in a pouch, which faces outwards and slightly towards the mother’s chest, two teats are present. At 6 or 7 months, the joey has left the pouch, it is fully weaned and independent by 12 months. The mother’s milk is poorer in nutrients than with other marsupials, and the joey is fed milk for a longer time. Joeys will often consume its mothers faeces in order to gain the correct gut flora of bacteria in order to digest eucalyptus leaves in the future, but the mother does not produce special pap in the way of a true Koala. Home ranges are generally small and overlap with others, but these animals are not very social, and fights often break out. Several males may court a single female when she is receptive, and some amount of fighting and resistance preludes the mounting and insemination. Both males and females produce a strong musky scent which is stronger when they are breeding. Lifespan is 12 to 15 years.

This species of mammals was discovered by Timothy Donald Morris, Adelaide, Australia.

Marsupial grizzly (Gravipossum ursinus)
Order: Diprotodontia (Diprotodontia)
Family: Predatory possums (Carnopossumidae)

Habitat: forests and woodlands of Meganesia, plains of southern part of continent (up to coast of Eyre Gulf) and Great Dividing Ridge.

Picture by Alexander Smyslov

In Holocene Australian marsupials had suffered significant damage from the introduction placentary predators to Australia, and from destruction of megafauna by first aborigenes. At the continental part of Australia marsupial lions (Thylacoleo), marsupial wolves (Thylacinus) and marsupial devils (Sarcophilus) had died out. In historical time the Tasmania Island remained last shelter of marsupial wolf (smaller, rather than its continental species) and marsupial devil (also smaller than species exterminated at the continent). The place of marsupial predators on continent had been actually occupied by people and feral dogs, dingoes. In Neocene when both people, and placentary predators had died out of different reasons, marsupials had started to evolve actively, occupying the exempted ecological niches. Among new marsupial predators of Australia descendants of both “true” predatory marsupials (Dasyuridae), and other animals passed to predating in parallel to them had appeared. In Neocene possums had made the second attempt to become carnivorous creatures (marsupial lion was the first and rather successful attempt). Being not able to compete with dasyurids, carnivorous possums had turned to massive animals, similar to bears by constitution. The size of marsupial grizzly, largest one of them, reaches 3 meters in length at weight about 500 kg.
Marsupial grizzly is one of largest species of marsupial mammals of the world. Longteeth wombats, descendants of Holocene wombats, reach even bigger size, but among possums this species is true giant. Even huge New Zealandian species of possum is much smaller.
Marsupial grizzly is very similar to massive bear with rather short extremities and back curved upwards. At it there are plantigrade extremities armed with sharp claws up to 10 cm long. Being attacked by predator, the marsupial grizzly defends, rearing on hinder legs and delivering crushing blows by front ones. It had not lost the ability to climb on trees though adult animals do it hardly. But young marsupial grizzlies spend a lot of time in crones of trees where they eat foliage and fruits, and ravage bird's nests. Adult animals feed mainly on the ground.
Possums known to people differed in long tails. At marsupial grizzly which spends on trees only small part of life, the tail became short and thick. It has lost past function of the balance weight and the “fifth paw”, and now in it the stock of fat is accumulated, helping to go through fodder shortage.
Head at this marsupial is rather large and massive. Ears of animal are short and round; nose is big and lips are mobile. Eyes of marsupial grizzly are small – the animal is short-sighted, and in search of food bases at sharp sense of smell. Marsupial grizzly has yellowish-grey fur with dark paws and nose bridge. Stomach of animal is white, on back from waist up to the basis of tail narrow black strip stretches. Feet and hands of animal are covered with thick cornificate skin.
Jaws of marsupial grizzly are short and have slightly increased canines and wide molars. Strong chewing muscles help this marsupial to chew fibrous parts of plants and heads of bones of large animals. This species of animals partly plays a role of scavenger in ecosystems of southern and eastern parts of Meganesia. It finds rests of catch of large local predators, and eats them almost completely: after the feast of marsupial grizzly only separate vertebrae and bones of legs remain from carcass of animal. Also it can drive away smaller predators from catch. The males of this species not burdened with cubs bearing can go fishing in shallow rivers and lakes.
Marsupial grizzly is not completely carnivorous species of marsupials: it is omnivore, and whenever possible willingly eats vegetative food. With the help of long claws animal digs out roots of ferns and other eatable plants. It can dig out holes of small animals just as it was done by bears in Holocene epoch. Because this animal is omnivorous, at it the increased intraspecific aggression characteristic for carnivorous species is not shown. Besides females at marsupial grizzly are larger, rather than males, therefore cubs are not threatened with danger of attack from their side while they stay with mother.
Brooding pouch at this species of mammals opens back, and there are four nipples in it. Fertility of the female of marsupial grizzly reaches ten cubs, but only four of them receive an opportunity to survive, and usually two cubs survive up to independence. In the beginning the posterity of marsupial grizzly is “worn” in mother’s brooding pouch over half-year. After that cubs change to back of mother, and keep by paws for her wool. The posterity stays with mother up to one-year-old age, and right when young animals abandon the female, it becomes ready to pairing again.

At the eastern slope of Great Dividing Ridge, in humid mountain woods the relative of this species, the marsupial panda (Gravipossum paraailuropoda) lives. This species is much smaller, rather than marsupial grizzly: the adult female weighs about 300 kg at length of body up to 2 meters, and the male is 25 – 30 kg lighter. In food predilections marsupial panda differs from marsupial grizzly by appreciable bias in vegetarianism. The food of animal origin amounts a small part of diet – marsupial pandas eat eggs of ground-nesting birds, and willingly consume carrion. Frequently animals search for forage on banks of mountain rivers, feeding on water invertebrates and local migrating fishes of Galaxiiformes order. But the basic food of this animal is made of roots and leaves of grassy plants, and also sprouts of bushes. Living in cool mountain climate, marsupial panda differs in rich wool. At this animal there are black head, shoulders and back, rounded white spots above eyes, grey sides and back part of body. The tail of marsupial panda has snow-white inner side which is used by animals for submission of signals to congeners.
Fertility of marsupial panda is insignificant: the female gives rise to no more than five cubs from which only one or two ones survive up to independence. Life expectancy of this animal reaches 40 years.

Marsupial biruang (Carnopossum heliarctoides)
Order: Diprotodontia (Diprotodontia)
Family: Predatory possums (Carnopossumidae)

Habitat: mountain and lowland rainforests of north and northeast of Meganesia.

Picture by Alexander Smyslov

In Neocene Australia and New Guinea had merged to unite land massive named Meganesia. This continent continuously moves to the north, to the equator, “crushing” edges of lithosperic plates of Indonesia. Actually, this circumstance became the reason of raising of northern part of Meganesian lithosperic plate.
Movement of continent has caused the considerable changes in climate of territories included in continent. The northern Meganesia in Neocene is in the area of equatorial climate that has positively had an effect on nature of continent. The north is covered with rich rainforests. And in forest swamps rivers originate and flow to the south and carry water to areas represented rigorous waterless deserts in Holocene.
Rainforests of the north of Meganesia are rich in life. Various birds, reptiles and amphibians, and also unnumerable species of insects live here. Besides, the forest canopy is inhabited by various small and medium-sized mammals, and large species of mammals are found in underbrush. Among them there are descendants both of native Australian and New Guinean species, and descendants of species introduced by people.
Rainforest is a habitat of rather large species of marsupial mammal which is named marsupial biruang. It belongs to group of carnivorous possums classified in family Carnopossumidae. Its close relatives are huge marsupial grizzly living in the south of continent, and marsupial panda – smaller species from mountain areas at the east of the continent. Marsupial biruang is the smallest representative of carnopossumids: weight of adult animal is only about 60 kg. It is the ecological analogue of Malayan bear, or biruang, known in human epoch – hence the name of this species.
Marsupial biruang has robust constitution and rather short limbs. Similarly to all carnopossums, it has very short tail which does not take part in tree-climbing. On paws of animal long hooked claws grow; with their help marsupial biruang easily gets on high trees. Fingers of animal are mobile and permit it to gather very small objects and to catch insects. The wool of this animal has black or dark brown color, and only above eyes there are two light grey spots. At young animals spots above eyes are absent. On hands and feet wool is thin, and through it grey skin of animal is visible.
Eyes of animal are directed forward, and provide enough wide sector of three-dimensional vision. Ears at marsupial biruang are short, rounded, slightly jutting out from wool. At this animal there are rather short muzzle and increased forward cutters. Molars are obtused: their shape is characteristic for omnivores.
Marsupial biruang uses for life all levels of rainforest – from underbrush up to forest canopy at height over 20 meters. This is sluggish single animal marking borders of territory with the help of musky liquid secreted by two glands at the root of tail.
This animal is omnivorous and easily finds enough of food. It eats fruits of various tropical trees, sappy leaves and stalks of epiphytic plants. Also this animal catches large insects and digs out of ground worms and grubs. If the opportunity is represented, marsupial biruang catches little mammals and ravages nests of birds. Any animals from insects and snails up to vertebrates weighting up to 3 – 4 kgs become its prey.
Having caught prey, marsupial biruang perches on wide strong branch of tree, sits on hinder legs and eats food, holding it in forepaws. After meal the animal licks wool by long tongue, and “washes” by forepaws like cat. Marsupial biruang is active in day time, and only in hottest time of day sleeps till some hours, having chosen a shady place.
At this species of marsupials the female is larger and heavier, than the male. Animals do not form constant pairs, and meet only for the period of pairing. The pouch at the female opens forward – when female swarms up a tree, such position of pouch is safer for the large cub. The female bears only 2 – 3 rather large cubs (large to measures of marsupials – newborn marsupial biruang weighs about 10 grammes). Some months later only one cub from the litter usually survives. The female looks after it for a long time: the cub stays in pouch till about seven months. Having left the pouch, it follows the female and learns to search for food till about three – four months. At this time the female can couple with another male and bear new posterity. When the new cub is born and gets into a bag, the female starts to show aggression to the previous cub, and it passes to independent life.
Sexual maturity at marsupial biruang comes at the age of four years, and life expectancy reaches 40 years and more.

Great manu, or Marsupial colugo (Manupterus magnus)
Order: Diprotodontia (Diprotodontia)
Family: Manupterids (Manupteridae)

Habitat: North Island of New Zealand, forests of various types.
Marsupial mammals are quite widely represented in the fauna of Neocene New Zealand. They descend from human-introduced species, mainly the brushtail possum (Trichosurus). Among the descendants of this animal there are both giants with unusual appearance, for example, ursine cuscus and marsupial pardus, as well as smaller species of an arboreal lifestyle. Some of them form the endemic Manupteridae family, whose representatives are remarkable in the presence of a gliding membrane and the ability to make gliding jumps (hence the name: in the Maori language, the word “manu” means a kite).
Great manu, or marsupial colugo, is the largest species of this family. Its body length is 35 cm, and its tail is up to 40 cm long. The weight of an animal can reach 800 grams. Females are slightly smaller than males. The head of great manu is shortened, but the muzzle is slightly pointed. Ears are medium-sized and almost hairless; eyes are large. Tail is covered with long hair. A wide gliding membrane covered with hair stretches between the wrist joint of the forelimbs and the ankle joint of the hind legs. Females have a well-developed brooding pouch that opens forward. The structure of the limbs of large manu shows the adaptation to the arboreal lifestyle: the first and second digits can be opposed to the other three ones for a better grip on the branches. The body of marsupial colugo is covered with thick, soft reddish-brown fur, and the tip of its tail is black. There is also a black spot on the tip of the muzzle. The underside of the body is light gray.
Great manu is an exclusively arboreal mammal that never descends to the ground. It usually moves slowly along the branches of trees, embracing its hands and feet around them, and easily crosses long distances due to its ability to glide to a distance of more than 50 meters. During the gliding jump, marsupial colugo stretches its gliding membrane, and its long tail serves as a rudder and balancer.
For great manu, like for all members of its family, a nocturnal lifestyle is characteristic. During the daytime, these animals sleep in tree hollows or in occupied bird nests (the same shelters are used by females when raising offspring) and only at dusk they wake up and start searching for food. Marsupial colugos are mainly herbivorous: their food consists of juicy fruits, flowers (including their nectar), tree sap and vegetative parts of plants. Large insects and small vertebrates complement the vegetarian diet.
For animals of this species territorial behavior is characteristic: each male owns a territory of a certain size, the boundaries of which are marked with odorous markings. When two males meet, the smaller one usually retreats, and skirmishes take place only rarely. Females move freely through the territories of males.
Living in a subtropical climate, great manus have only a slightly expressed seasonality of reproduction, and the appearance of offspring is possible for most of the year. Being ready to mate, the female emits a scent that attracts the male. The male’s participation in reproduction is limited only to mating. Two weeks after it, the female gives birth to one to three tiny joeys, which then develop in a brooding pouch for about 100 days. After leaving it, the joeys stay with their mother for several more months, and she carries them on her back. Young individuals become sexually mature at 1.5 years of age. One female can have two litters in a year.
The lifespan of great manu does not exceed 11 years. Birds of prey and tree-climbing predators from among mammals pose a danger to great manus, especially to young individuals.

Pouched Un-margay (Thylofelis arboricola)
Order: Two-front Teeth (Diprotodontia)
Family: New Zealand Predatory Marsupials (Paradasyuridae)

Habitat: Forested areas of the North and South Island of New Zealand, including mountain forest, conifer forest, tropical forest etc.
The introduction of different foreign mammal species to New Zealand by man, had a devastating effect on its fauna in the Holocene, but presented new opportunities for evolution in the Neocene.
The Brush-Tailed Possum (Trichosurus vulpecula) gave rise to several Neocene forms here, including the predatory Paradasyuridae, which converged upon both cats, and extinct marsupial lions (Thylacoleo). This group includes great apex predators such as the Marsupial Pardus, but also smaller cat-like arboreal predators such as the Pouched Un-margay.
This marsupial resembles a partway between a small jungle cat, and its ancestral form, the possum. Adults reach up to 50 centimetres in body-length, tail is a little longer again than the body, reaching 60 centimetres, weight may be up to 4.5 kilograms. Limbs are powerful and flexed, ending in gripping paws that bear large curved claws, hands have a large semi-opposable thumb while the hind foot has a large opposable toe to grip branches. This animal appears more slender than its ancestor, spine is sinuous and flexible, animal is able to leap between branches, or pounce upon prey with ease. Tail is long and bushy, and ends in a large black tuft. Skull is large and rounded, eyes are large and face forward, in this way it resembles a small cat. Coloration is yellowish grey with a darker back, irregular black spots and cross-stripes towards the rump, tail tip is black. Ears are large, pointed and movable, resembling its ancestor, hearing is keen. Face is covered in a black “mask” around the eyes and mouth, nose is naked and dark pink. Paws are covered in black hair on the upper side, soles of feet are bald and pink. Its dentition recalls both Holocene possums and extinct marsupial lions, incisors are large and pointed, prey is killed with a bite to the throat. Premolars are large and blade-like, serrated, molars bear short pointed cusps, rearmost molars have rounded cusps for crunching small bones.
Pouched Un-margay is an adept tree-climber and spends most of its time in the trees, it can quickly run along branches and up and down trunks headfirst. This animal is a nocturnal predator of usually vertebrate prey, diet includes birds, rodents, and other kinds of small marsupial such as possums, large insects and lizards are sometimes taken, and they will eagerly consume nests of bird eggs or hatchlings. Prey is stalked from cover, and leapt upon in a long pounce much like a cat, they may drop down from branches above onto prey, or drive them to the tips of branches. Most prey is killed with a powerful bite to the throat, large incisors sever the windpipe and crush the neck. Calls of this animal include a coarse hiss or guttural screech when alarmed or excited.
Adults are solitary outside mating and courting, mating may occur year round but reaches its peak from September to November. Mating is promiscuous and opportunistic, individual males may sire multiple young within a year. The male will consort with the female for up to 2 weeks, mating several times, gestation is up to 16 days. Female gives birth to a single joey, small and pink, which migrates to the pouch, development inside the pouch lasts up to 6 months. After this time, the joey may be left in the mother's den or cling to her mothers back, and remains with her for up to 7 months. Sexual maturity is reached at 1 year old, and lifespan may be up to 16 years, predators include hawks, eagle keas, and on the ground they are vulnerable to canids and the Ruacapangi bird.

Night marsupial lemur (Nyctiphalangeropsis strigops)
Order: Diprotodontia (Diprotodontia)
Family: Marsupial lemurs (Phalangeropsidae)

Habitat: rain tropical woods of Meganesia.

Picture by fanboyphilosopher

The canopy of tropical rainforests stretched at height 20 - 40 meters gives a plenty of opportunities for adaptation to various live creatures. Among its inhabitants it is a lot of marsupial mammals. Those species have survived at the border of Holocene and Neocene, have inherited from missed species many free ecological niches, and have occupied them, having evolved to fantastical lifeforms. The competition between inhabitants of rainforest canopy can be very rigid, therefore during evolution live creatures developed to lower it as much as possible. Certainly, it is possible to become the specialized “expert” in consumption of the certain kindss of forage, and it is possible simply to live and not to prevent to another ones. One of animals living in this wood had made it.
When night falls on wood, the majority of wood inhabitants hides in tree-trunk hollows and nests and falls asleep. But some animals just at this time wake up and quicken. Among them there are various insects, frogs, lizards, some birds, and also small mammals covered by black wool with white marks. Their movements are very similar to movements of monkeys; their heads are big, have high cheek-bones and large “owline” eyes. Animals keep in small group, supporting contact with the help of quiet chirp. They are similar to small monkeys, but they are not primates at all, but descendants of cuscuses – night marsupial lemurs.
The night marsupial lemur is insignificant: length of its body is about 20 cm, tail length – about 30 cm. All paws of these small mammals are adapted to branch gripping: on forepaw there is well advanced thumb, and toes on hinder legs are opposed to each other by two groups: joined together I, II and III against joined IV and V. Bent claws grow on ends of fingers and toes. The animal moves on trees like squirrel: it runs on branches and swarms up trunks, clinging by claws against bark. Due to tenacious paws night marsupial the lemur dexterously swarms up the thinest branches. It is able to jump from tree to tree like monkey: having shaken on thin elastic branch, the small mammal makes jump some meters long. During flight in air the mammal stretches paws in sides to glide a little bit and thus to increase range of jump. The prehensile tail increases opportunities of animal: due to it night marsupial lemur can hang on branches.
The nocturnal habit of life is reflected at the appearance of this animal: eyes of the night marsupial lemur are very large, and because of it the obverse part of skull looks rather wide. On muzzle of mammal long whiskers grow with which help the animal finds way in dark night wood. Colouring of wool is coal-black, but for recognition of neighbours at night marsupial lemurs there are contrast marks – white stains on chest and tail tip. Around of animal’s eyes there are rings of white wool because of what this small mammal looks a little horribly: rings create illusion of eyes belonging to larger animal. Eyes of this marsupial lemur are yellowish-brown; pupils are vertical, as at cats. This animal distinguishes colors badly, but it is capable to see world around even at weak light of stars in moonless night.
At night marsupial lemurs there is good hearing, though auricles very short. But the ear aperture at them looks like a crack, and on back edge it is edged by fringe of rigid fur functionally replacing an auricle. Due to sharp hearing the animal can search for insects in darkness, and frequently to it succeeds even to hear flying owl: it is rather useful property for nocturnal animals of small and medium size.
The night marsupial lemur is a sociable animal; it lives in groups of 3 – 5 individuals. All group consists of male and several females, and also of cubs have not reached independence. These animals spend day in tree-trunk hollow on their territory. They know an arrangement of all suitable shelters on their area, and each morning they stay in new one. By this way animals prevent the parasite breeding and hide their resting place from predators.
Night marsupial lemurs wake up, when day time heat falls down, and day time predators search shelter to lodge for a night. Usually dominant male or the main female shows itself first from tree-trunk hollow. The animal cautiously smells air, convincing of safety, and then comes out on the branch. After it other members of group appear. Animals clean wool, stretch, and start to inspect territory. They move on branches in a line, keeping a distance. During the night small mammals become especially cautious: at this time owls fly to hunt. To protect itself against attacks of these birds, night marsupial lemurs choose way in richest branches, and jump from tree to tree one by one, stopping for a little time on trunk after landing. Other enemies of these animals are snakes. The silent rustle similar to sound of the moving snake is the most terrible sound for night marsupial lemurs.
The group marks borders of the territory with the help of secretions of repugnatorial glands located in armpits. For this purpose they simply drag branch between body and paw. All members of group mark territory in same place, but on different branches, therefore smells of separate animals do not mix up also any newcomer can estimate number of animals protecting this territory. However, dominating male will do not be against at all if the newcomer will appear the female. When it is a lot of forage, it can admit to clan even other male, but already beforehand a role of satellite and “whipping boy” will be determined to it, and it will druggle at the end of group. But the solitary animal in almost cases is restrained with such role: it is easier to notice danger together. During the movement group supports contact: animals utter chirp and abrupt sounds similar to bark.
Night marsupial lemurs are omnivorous: they will ravage the bird's nest or will tear off ripe fruits from branch with the same pleasure. In searches of vegetative forage they are guided basically by sense of smell, correctly distinguishing ripest fruits by smell. One more dainty is thick juicy stalks of some orchids. The best food of animal origin includes insects and spiders. If fruit appeared worm-eaten, these mammals will to have eaten it entirely, right including caterpillar. The special dainty is delicate soft termites. At night these blind moisture-loving creatures leave their shelters, and night marsupial lemurs willingly lick them off from bark.
Seasonal prevalence in breeding at night marsupial lemurs is not present: practically at any time it is possible to find groups with cubs. Female twice per one year gives rise to 7 - 8 cubs though it can feed only four ones. The pouch opens back at this species. Cubs spend in it about two months, then they get out on back of mother and travel on it, seizing its wool. This time is the most important for their further life: cubs study to search for food and seize skills of tree-climber. When they wean from dairy diet, their connection with mother weakens. Cubs can get on backs to other members of group though those can be not so pleased with it, and seldomly bear too long driving another's “youngs” on the back.
Sooner or later young animals abandon clan. They go to “neutral” (“drawn”) boundary territories of different clans, and gradually teenage groups break up. Young females more often succeed to join to other clan, and the destiny of males develops more dramatically: at them probability to finish the barchelor life in stomach of the snake or an owl is most of all. Occasionally the young male finds teenage group and expels from it other males, forming a high-grade clan. Being lucky it can “overthrow” the old male and take hold of available clan.
Life expectancy of the night marsupial lemur is short: it seldomly lasts more than 10 years.

Hook-fingered kangaroo (Gravimacropus macrocheirus)
Order: Diprotodontia (Diprotodontia)
Family: Kangaroos (Macropodidae)

Habitat: light forests and bush thickets of Southern, Central and Eastern Australia, foothills of Great Dividing ridge.

During the evolutionary history kangaroes belonged to among the most successful marsupial animals of Australia. They evolved rather quickly, adapting to changes of world around, and in historical epoch competed on equal terms with sheeps and camels introduced by people. In Neocene the significant part of domestic animals introduced by people to Australia, had died out, and only camels evolved to some species adapted to various habitats became real competitors of kangaroes.
Kangaroes had also evolved, and among them various kinds had appeared: some of them eat foliage, others graze, and some ones even eat insects and carrion. Climatic conditions of Neocenic Australia favour to development of large life forms, and among kangaroes one such species had appeared.
The largest kangaroo of Australia is the hook-fingered kangaroo. It is huge species up to 3 meters in height in biped pose. The hook-fingered kangaroo has shape characteristic for representatives of this family, but adjusted for larger size and massive constitution. This animal weighs about 250 - 300 kg, therefore it jumps slowly and hardly, more preferring to move by original slowed down “gallop”, moving alternately pairs of front and hind legs. Forepaws of the hook-fingered kangaroo are adapted to such type of movement: the animal leans on the external side of long hands covered with thick skin, similarly to gorilla. On fingers of this animal thick hooked claws grow. At movement the animal pushes from the ground by tail which is considerably short in comparison with tails of usual species of kangaroes. On the bottom side of tail the cornificated covering, similar to callouses developing on legs of camels, is advanced. But this “callous” does not serve for protection against burns as at camels, but provides the best cohesion with ground at the movement.
Hinder legs of the hook-fingered kangaroo are lengthened: it is a characteristic attribute of all kangaroes. But they are not much longer than forepaws, short of a foot. Foot at this species of kangaroo is long and elastic, and claws are not sharp, but to a greater extent hoof-like and blunt. The hook-fingered kangaroo does not concern to list of fast runners: it prefers to not escape from predators in flight similarly to the majority of its congeners, and to protect itself in close combat. This animal defends against enemies by impacts of forepaws, gashing it by terrible lateral impact strengthened with a turn of all body. This animal counter-attacks large enemies and tries to tear them by claws of hinder legs.
The wool of hook-fingered kangaroo is colored bright - red. Head and forepaws at it are dark, almost black, and hinder legs and the bottom part of tail are lighter, than the basic colouring of body is. On head there is the extensive white “mask” covering muzzle, eyes and a part of bottom jaw.
This animal is original analogue nowadays extinct sharp-clawed perissodactyls chalicotheres (Chalicotheriidae). The hook-fingered kangaroo eats leaves of bushes and trees. Usually it is feeding, standing on hinder legs and tightening tree branch to a mouth by long forepaws. Also it eats soft species of grasses, not competing with other species of kangaroes eating rigid siliceous graminoids.
Chewing muscles are advanced rather poorly at it: the animal chews a little, and the food is processed mainly in the complex stomach consisting of three chambers. Symbiotic protozoans improving quality of food digesting, live in stomach of this species. The feature of physiology of the hook-fingered kangaroo is the ability to make some of metabolic water which is formed at fat oxidation. This adaptation helps this animal to live long time without water: the hook-fingered kangaroo comes to the watering place only once a week, and even less often.
Jaws of hook-fingered kangaroo are short, and the obverse part of skull is short and expanded. Eyes are shifted in sides and provide the good circular field of view. Also at the animal there are wide mobile ears: hearing at the hook-fingered kangaroo is keen. The olfactory cavity also is expanded: therefore the head of animal has no “deer” shape usually characteristic for kangaroes. Wide ears and nasal cavities help large animal to cool itself in strong heat.
This species of kangaroo is solitary animal though it does not avoid a company of congeners. In places rich in forage this species meets by small groups of 4 - 5 adult animals. Usually animals keep together during pairing. The courtship season at this species is strongly dragged out, and females ready to pairing meet the most part of year, except for the droughtiest months. The female ready to get posterity, emits the special smell on which it is found by males. Usually one female is looked after with true “retinue” of males. But one of them shows the greatest activity, driving other ones away. Fights between males are limited to struggle with the help of forepaws. Kicks in stomach of the contender, characteristic for other kangaroes, at this species are excluded: animals are too massive for it.
After short pregnancy the female gives rise to one small cub, which should get into parental pouch itself similarly to posterity of all marsupials. The period of bearing of posterity in pouch at the hook-fingered kangaroo is very long: about half-year the cub constantly sits in pouch, sucking milk, and still almost half-year it is hidden in it at the case of danger. But up to age of fifteen months the cub continues to suck milk of mother though to another nipple its younger brother has already attached. Young animals differ from adults in monotonous colouring of body. It changes approximately to three-year age, and four-year-old animals already can breed. Life expectancy at this species may be over forty years.

The idea of existence of this animal was proposed by Simon, the member of forum.

Ghostly, or nocturnal kangaroo (Neomacropus pallidus)
Order: Diprotodontia (Diprotodontia)
Family: Kangaroos (Macropodidae)

Habitat: mountain forests and jungles of Meganesia.

Picture by Pavel Volkov

Kangaroos survived the human era with significant losses: large and narrow-area species disappeared, as well as a number of tropical forms. And yet these marsupials remained one of the most successful Australian animals, competing on equal terms with the descendants of introduced ungulates. The surviving species easily restored biological diversity after the anthropogenic crisis and gave rise to a number of new forms, including those with unusual lifestyles. In Hawaii, where kangaroos were introduced, a species similar to Holocene tree-kangaroos evolved. And in the mountain forests and jungles of Meganesia, a ghostly kangaroo appeared, a descendant of the red-legged pademelon (Thylogale stigmatica).
This species is a fairly large animal of a light constitution. Body length is up to 1.5 m, tail length is 90 cm, weight is 36 kg; males are larger than females. The coat color is grayish-brown and rather pale. The back is drastically different in color from the sides and belly: there is a black saddle-shaped spot on the back, and the shoulders and neck of the animal are also of black color. This coloring distorts and breaks the overall contour of the animal’s body, making it difficult to recognize it in the dark. Eyes are large and may shine red in the moonlight due to the presence of tapetum lucidum. Ears are wide, rounded, and covered with white fur on the outside. This species has a keen sense of smell; the mucous membrane of the nasal cavity forms small folds that enlarge the sensitive area.
Like its ancestor, this animal is nocturnal, sleeping in bushes or in crevices between rocks during the day. This species is almost exclusively herbivorous, feeding on leaves, grass, fruits and mushrooms, and can sometimes trample and eat small vertebrates, but this is rather an exception. Ghostly kangaroos are social animals, living in pairs or small groups of relatives (male and female with young or siblings). A solitary animal experiences stress and tends to stick to a group of congeners. Outside of the breeding season, males tolerate the presence of a competitor, but in the presence of a ready-to-mate female, males begin to treat each other aggressively. There are often groups of bachelor males of various ages.
Breeding takes place from October to June. Unmated males track down females by odorous secretions and arrange fights among themselves for the right to mate. At this time, they rise higher on their hind legs and utter low grunts, trying to impress the female. When rivals meet, a fight including scratching with their front paws and kicking ensues – veterans of fights often carry numerous scars on their front paws and shoulders. The female stays with the strongest of the males. The family male does not arrange fights, although he often has to protect the female from rivals – young “bachelors”. In the absence of a rival, the male devotes a lot of time to courting the female: he chases her, uttering grunts, and presses against her, licking her fur. Pregnancy lasts for 32 days. 2-3 joeys are born, which spend the first 9 months in the mother’s pouch, after which they begin to get out of it and taste the food of adult animals. At the age of one year, they no longer hide in the pouch, feed only on grass and flee from the enemy along with adult animals. At this time, the female already carries the new brood in her pouch. At the age of 18-20 months, ghostly kangaroos are completely independent. Maturity comes at the age of 2 years, and life expectancy is up to 27 years.

Hobyah-Wallaby (Arborogale pithecoides)
Order: Diprotodontia (Diprotodontia)
Family: Kangaroos (Macropodidae)

Habitat: Warm and temperate forests of South-Eastern Australia, cool forests of Great Dividing Range.
During the Pleistocene and Holocene, kangaroos and wallabies experimented successfully with tree-dwelling habits. Not only were there Tree-Kangaroos (Dendrolagus), but a separate kind of Ice Age wallaby capable of climbing trees to feed (Congruus). In the Neocene, there are no descendants of Dendrolagus due to endangered status and habitat loss, but more unpretentious wallabies (Petrogale), have taken to the trees and produced broadly similar forms. Not only this, but it also occurred convergently in Hawaiian Islands, from invasive members of the same group, Monkey Wallaby.
These Meganesian Tree-Wallabies are typified by the Hobyah-Wallaby, which is found over a large range in south-eastern Meganesia. It is named after mischievous imp of Australian folkloric fiction. Bodily it resembles a tree-kangaroo, having a short body, flexible hunched back, shortened feet, and powerful arms as long as the hind legs, with big hand claws. Hind feet are flexible and able to turn soles inward, feet can move independently to “walk” along branches. The neck is upright and flexible, and its head is somewhat more massive than a typical wallaby. Snout is of fair length but deeper with an arched nose, lips are large and flexible, not split, forming a small proboscis to aid in feeding. Eyes face more forward, allowing animal to judge distance when climbing and jumping, it is able to see in ultraviolet and can perceive the colours of fruits or flower heads. Ears are large and mobile, but rounded at the outer edge, resembling mouse’s ones. Tail is long and flexible with a “brush” at the end, in order to balance the animal; it is able to make short leaps between trees and even may descend to the ground by leaping as far as 6 meters. It moves about by clambering between and along large branches, and it is able to ascend vertical trunks.
Hobyah-Wallaby reaches the size of a monkey or a child, up to 20 kilograms, males are larger than females, but both are equally muscular to aid in climbing. Pouch is large and faces forward and a little upward so that joey will not fall out. Coloration is a dark brownish grey, with thick blackish-brown cross-bands on the back and hindquarters, extremities of limbs, tail and face are all darker blackish brown. Skin of ears, nose and soles of feet are black. Its diet consists of the soft leaves of broadleaf trees, eucalyptus and other coarse leaves are not taken, fruits and flowers are eagerly consumed, as are wood fungus.
As with Holocene Tree Kangaroos, it is generally solitary, individuals have a distinct large territory, and only come together to mate. Males court females in the cooler wetter part of the year, but female is receptive for much of the year. Males seek females by smell, both sexes release a musky glandular odour advertising receptiveness, and in the case of males, vigour. Opposing males fight by biting and “boxing” with fore-paws, and attempt to drive the other to climb down and retreat. This wallaby is usually only active during morning and late afternoon, including dawn and dusk, individuals hide during the middle of the day.
Females will give birth twice a year, and they are able to rear a new fetus when the older joey is still suckling. Joey starts to leave pouch and climb at 3 and a half months, and moves independently at 4 and a half months, weaning 2 months later. During following year’s courtship the young joey will leave the female, becoming sexually mature at 2 years old. Lifespan is up to 30 years. Predators include large raptorial birds, and climbing predatory marsupials, stray joeys may be consumed by pythons or monitors.
Related species is the Imp-Wallaby (Arborogale agilis) found in the tropical woods and rainforests of north-eastern Meganesia. It differs by somewhat smaller size, weight usually of only 15 kilograms. Colour is a yellowish brown, with dark-reddish cross-bands along the back and hips, extremities are coloured chocolate brown, as is the face. It also differs by more slightly shaped head, a little more similar to a typical wallaby, lip forms a flexible point as with its relative. Fruit makes up a greater portion of its diet than its relative; it will consume the flesh of many non-poisonous tropical fruit. As against relative, breeding is preferentially done in the drier months when there is less risk of storms and flooding.

Caprine Wallaby (Capromys dexter)
Order: Diprotodontia (Diprotodontia)
Family: Kangaroo (Macropodidae)

Habitat: woods, scrub land and forests of Eastern Meganesia, from Great Dividing Range into sub-tropical zone.

Picture by Pavel Volkov

Smaller herbivorous marsupials such as wallabies, managed better against invasive species, and habitat loss during the Holocene human occupation of Australia. The forms left after the extinction of man, radiated into niches made absent after the Holocene extinctions.
The genus Petrogale, rock-wallabies, survived and speciated in some numbers, giving rise to not only larger species, but arboreal and even predatory forms. Caprine Wallaby is a kind of remaining transitional form between rock-wallabies and Neocene tree-dwelling species, a fair-sized wallaby that is able to feed both on the ground, as well as by climbing rock faces or large trees and shrubs.
This species generally resembles a rock-wallaby, apart from somewhat shorter and broader hind-feet, and longer more muscular arms, ending in powerful clawed hands. Wallaby reaches a weight of about 22 kilograms and a length of up to 130 centimeters, and is a mixed feeder with a strong bias towards the leaves and buds of trees and shrubs, as well as soft herbs. This marsupial spends a great deal of its time climbing trees and shrubs in order to feed on leaves, adults are able to scale the trunks of large and mid-sized trees that to dot have a long shaft of bare trunk. Individuals mainly climb by clambering between branches, and walking along boughs (foot bones are flexible enough to alternate stride), branches and leaves are pulled towards the mouth using its hands. Face is elegant and generally similar to a Holocene wallaby, but slightly deeper in the jaw; dentition is adapted to chew a wide range of kinds of leaves, shoots and buds. It also spends time feeding on the ground, on understory plants such as shrubs and herbs, as well as sometimes climbing hilly outcrops and crags in order to feed on inaccessible growth. In this physical adaptability of feeding, it is so named Caprine Wallaby, similar to a feral goat which may climb trees and rocks to consume plants.
Coloration is a fawn-grey colour, with a pale cream coloured belly, hands, feet and tip of tail are all a dark chocolate brown, head is dark brown with a pale “spectacle” marking around the eyes and mouth. Skin of nose, inside of ears and soles of hands and feet are all brownish pink. Ears are long and slightly pointed, recalling a rabbit or other wallaby, lip is split and rather long, flexible in order to aid feeding. Eyes are large and dark, sensitive to movement and shape especially in order to detect predators.
Caprine Wallaby is usually most active in the morning and afternoon, including dawn and twilight, by day it will usually hide in lee of a crag or up a tree in order to rest. This species lives usually in small groups consisting of a breeding male, one or two females, and their mature young, male youth are usually expelled from the group upon reaching sexual maturity. Mating occurs in the cooler wetter part of the year, August until mid November, females are receptive throughout this time but usually only bear one young each season, second developing fetus may be delayed until the following season. Groups have fair-sized territories, where female strangers are tolerated, and interloping males driven out. During the breeding season, stray males may challenge family leaders for access to females, fighting by “boxing” with arms and kicking, as well as vigorous displays by thrashing and throwing branches and leaves with arms. Joey starts to venture out of pouch after 10 weeks, and is independent of pouch and weaned by 6 months, sexual maturity is reached at 2 and a half years usually. Lifespan is up to 25 years but usually shorter; predators include large carnivorous marsupials, birds of prey, varanid lizards and sometimes large snakes.

Monkey wallaby (Pithecomacropus agilis)
Order: Diprotodontia (Diprotodontia)
Family: Kangaroos (Macropodidae)

Habitat: rainforest of Hawaiian islands (Oahu, Molokai, Lanai, Maui, Kahulawi), forest canopy.

Picture by Tim Morris

Kangaroos never lived on Hawaiian Islands, similarly to representatives of other groups of ground and flightless mammal. But in human epoch they have appeared even in this isolated corner of Earth, being introduced there by people. And it was species of mountain wallabies Petrogale penicillata (brush-tailed wallaby) became extremely rare in true native land, in Australia, later. Pair of these animals has run away from a menagerie in the beginning of XX century, and was multiplied on Oahu Island. Decrease of ocean level till an ice age had permitted to this animal to settled on the near islands: Molokai, Lanai, Maui and Kahulawi. Obviously, this moving was unitary: Oahu Island is separated from them by rather deep Kaiwi passage which had kept in ice age, and obviously, it had been crossed casually by a little group of animals – founders of new population. And the further moving of wallabies to the east on islands of the Hawaiian ridge was blocked with Alenuihaha passage separating these islands from Hawaii Island. Therefore moving of descendants of marsupial immigrants on islands is limited to these islands. In the period when the volcanic island Hekeua had been formed, the part of populations of this kangaroos has almost disappeared, having kept in small amount only in rests of woods at coast. But later, due to characteristic for marsupials ability to fast breeding, the population of Hawaiian wallabies was restored. So these marsupials relieved by the nature of competitors, others large mammals, have remained on Hawaii.
The monkey wallaby has considerably changed a habit of life characteristic for ancestors. Now this is a forest animal, something similar to the “true” Holocene tree kangaroos of New Guinea. It is the small species of kangaroos: it is cat-sized animal, but seems larger because of long tail. This animal has found a fine ecological niche in woods and became the largest species of herbivorous animals in rich canopy of the Hawaiian rainforest.
Monkey wallaby dexterously swarms up trees. Joints of back extremities at it are very flexible, and the foot is partly swivels sideways: the animal clasps so a tree trunk more densely. On front and hinder legs hooked claws are advanced. Grown together toes on hinder legs serve for the toilet purposes. This animal clambers on trees “galloping”, working synchronously in pairs by forward and back extremities. Perhaps, the monkey wallaby is unique species among kangaroos, able to move back: this animal goes down from trees a tail first, serially grasping a trunk by front and hind legs. Similarly to monkeys, this animal can make big jumps from tree to tree, and is able to swarm up thin lianas dexterously. If the branch or liana is especially thin, animal is able to move on it similarly to sloth - a back downwards, clinging for a support by bent claws. A tail of this species is thin and long: in length it exceeds body and head taken together. Tail is not prehensile, but elastic: it serves as the balance weight during jumps and movement among branches.
The skull of monkey wallaby is rather short and wide, as gives to this marsupial the “monkey” shape. It is connected to several features of its habit of life. First, the important advantage to this species is the binocular sight assisting to estimate distance up to the next branch precisely. And second, the animal eats rather soft food: fruits and soft leaflets, therefore its jaws became weaker and have decreased in size.
Sight of the monkey wallaby has one feature: the animal can perceive ultra-violet light. Therefore animals of these species easily find among foliage green fruits covered with wax, reflecting this part of solar spectrum. Ears of the monkey wallaby are wide and mobile; animal has very good hearing. Ears are hairless, pink due to blood vessels appearing through skin: in hot weather vessels extend, and surplus of heat is emitting through ears.
Coloring of body of monkey wallaby is disruptive: head is black with longitudinal white strips stretching from nose to ear through eye, on forepaws and shoulders there is light red “cloak”, tail is grey with black tip. Waist and hinder legs are dark brown.
Being similar to monkeys externally, this animal is absolutely not similar to them by habits: monkey wallaby is solitary animal, and two adult animals can be together only in short courtship season. Monkey wallabies are very territorial animals. Each individual occupies territory about a quarter of square kilometer, and marks its borders by urine. This animal does not arrange constants shelters, and spends night in casual refuges. And adult strong animals spend the night even simply on branches.
Two times per one year the female brings posterity: one underdeveloped cub growing in pouch similarly to other species of marsupials. The three-monthly cub starts to get out of pouch, and at the age of four months it leaves mother’s pouch finally. About one month the young animal studies at mother in searches of forage, and then in courtship season she banishes the posterity. Young monkey wallabies begin able to breed at two-year-old age.

Deer wallaby (Neogale sylvanus)
Order: Diprotodontia (Diprotodontia)
Family: Kangaroo (Macropodidae)

Habitat: forests in the north and east of Meganesia, undergrowth.

Picture by Alexey Tatarinov

Unlike large marsupials, which became extinct soon after people arrival to Australia and New Guinea, the animals of small and medium sizes were able to adapt successfully to neighbouring humans and introduced placental mammals in Holocene. This trend expressed in many cases not only in Australia, but in the fact that the majority of native mammals belonged to marsupials, that gave a unique identity to the fauna made of descendants of survived species.
Among the marsupial survivors in the era of anthropogenic pressure there were the relatives of larger kangaroos – brush-tailed rock-wallabies (Petrogale penicillata). Their relatively flexible behavior, small size and wide range of habitats allowed them to outlive not only humans, but also the climatic cataclysms that greatly reduced the species diversity of the larger kangaroos. And the formation of a single continent of Meganesia had opened new ecological niches for development.
Deer wallaby of Neocene is one of the descendants of rock-wallaby. This is quite large animal, growing to sizes of red kangaroos of Holocene – 1-1.6 meters in height (the females are smaller), but much more lightweight, not heavier than 40 kg. Furthermore, when compared with other bipedal marsupials, deer wallaby has very gracile constitution; great part of its body seems to consist of highly elongated hind legs and tail, due to it deer wallaby, it seems, walks “on stilts”.
Despite the long legs, this animal is not very fast and gets tired very quickly during the chase – lung volume does not allow this animal to run for a long time. Therefore, like placental deer and antelopes it has very large ears and eyes, and is constantly on guard. At the slightest danger deer wallaby rushes away and hides in forest thickets: it has spotted coloration like deer of Holocene epoch – white spots on yellowish-brown background – and it is its main mean of defence.
Deer wallabies feed mostly on foliage of trees and shrubs, as well as on berries, flowers, low-growing epiphytes and other herbaceous plants. Their height and the ability to jump permit them even to climb on low trees and to browse their crowns, or to escape from predators. When climbing up a tree, deer wallaby makes vertical jump along the trunk, and at the highest point of the jump it grabs tree with its front paws. Then animal grabs tree with its hind legs and climbs onwards, pushing the tail into the trunk.
Deer wallabies can mate every six months. Like with the other marsupials, the pregnancy is very shortt and the youngs in the pouch also grow quickly. At one year age they are already independent and do not depend on their mothers, and may already have their own offspring. Young animals keep next to the older ones: they live in small herds numbering of 6 to 10 individuals of both genders and all ages. Males, however, usually leave their family upon reaching sexual maturity and go look for a new life companion. These are phlegmatic animals and the fights for females almost never happen. But while establishing relationships of domination, the dominant male of herd may bite the subordinate males in the areas of the scruff and shoulders. It also constantly displays its’ dominance in the group, pushing the subordinate males away from females and food sources. Thus it forces the competitors to leave the herd.
The life expectancy of deer wallaby is 15 – 20 years, but usually less than that.

Ostrich kangaroo (Theriostruthio unidactylus)
Order: Diprotodontia (Diprotodontia)
Family: Kangaroos (Macropodidae)

Habitat: grasslands and semideserts of Meganesia.

Picture by Tim Morris

Right after disappearances of mankind Australia represented the continent the most part of which had been occupied with deserts and poor savanna. In Neocene when Australia had merged with New Guinea to unite continent Meganesia, the climate promoted the occurrence of productive savanna. This area is inhabited by large flightless birds and descendants of camels introduced to Australia in ancient historic time, similar to giraffes and antelopes. But representatives of indigenous Australian fauna, marsupial mammals, successfully compete to them. Among them the original species became ecological analogues of antelopes and other quickly running herbivores had evolved.
The extreme degree of specialization to such habit of life is demonstrated by huge descendants of medium-sized wallabies of Holocene epoch, representatives of genus Theriostruthio (literally: “ostrich beast”) for which strongly expressed gracile constitution and ability to high-speed moving on a long distance are characteristic. These animals are a vivid example of convergence with running birds and fossil ostrich dinosaurs (Ornithomimidae).
Ostrich kangaroo is settled at the significant part of Meganesia where savannas were stretched. This animal lives in big herds numbering up to 100 individuals. These animals are constantly in movement, and continuously migrate, not staying at one place for a long time. Only in rain season when the grass plentifully grows, animals do not hurry up to leave rendered habitable places. It is very large species of marsupials – growth of the adult individual standing on rear legs reaches 3 meters, and the length including the tail is up to 4,5 meters.
Ostrich kangaroos strongly differ from species known in human epoch. At them there are very long and rather thin extremities. On hind legs of these animals there is only one middle toe with wide blunt claw similar to horse hoof. It is an attribute of quickly moving animal: usual speed of ostrich kangaroo makes 45 – 50 kms per hour, and animals pursued by predator accelerate momentum up to 80 - 90 kms per hour. These animals perfectly move on firm ground, but are compelled to avoid areas with soft and sandy ground.
Forepaws of this animal are approximately one third shorter, than back ones, and on them only three fingers with thick dulled claws remained. They are mobile enough to permit the animal to make some actions with their help. With the help of these fingers the female of ostrich kangaroo clears the pouch before the cub birth. Also ostrich kangaroos are able to break off tops of grasses by forepaws and to eat them, holding body in vertical position. Such pose is very characteristic for these animals: from height of the growth ostrich kangaroos easily notice predators.
Neck of this animal is longer and more mobile, than at usual kangaroos. If grass is short and thin, ostrich kangaroos can graze, moving on four limbs by slow “gallop” characteristic for kangaroos (ostrich kangaroos are not able to walk). Thus they graze grass by mouth.
The diet of ostrich kangaroos includes rigid and dry grasses, and also plants which can be inedible for the camelopes. In connection with such food jaws of ostrich kangaroos are short (their muzzle is similar to muzzle of large fossil kangaroo Procoptodon), and teeth have folded enamel and are adapted for masticating of highly abrasive food. Besides they accrue for rather long time, before their roots will be formed finally. It helps to compensate deterioration as a result of feeding on rigid vegetative food. Muzzle of ostrich kangaroos is wide and short, with strong chewing muscles. Its outlines are especially emphasized by large auricles. Such auricles are necessary for more effective heat emitting – ostrich kangaroos inhabit hot and dry areas of Meganesia. They can not drink for a long time, being content with metabolic water which turns out at oxidation of food and fat.
Wool of ostrich kangaroos is short and velvety, colored in light shades – at different individuals it varies from yellow up to almost snow-white and light grey. Light color of wool rescues animals from overheating – in places of their inhabiting it is almost impossible to find trees giving enough shadow.
Each year at the female of ostrich kangaroo only one cub is born. It comes into the world small and underdeveloped, and independently creeps to the pouch of mother. In pouch it attaches by mouth to the nipple and within several months almost continuously sucks milk. The eight-monthly cub ventures to leave the pouch for the first time, but at first attribute of danger it hides in it again though it is rather difficult for it to make it with its long legs. Gradually young animal starts to explore the world around, and passes to adult diet. At the age of fourteen months the young animal finally abandons the parent pouch and does not suck milk any more. The three-year animal already almost grows till the size of adult individuals, and at the age of five years ostrich kangaroos become able to breeding. Life expectancy of this animal reaches 40 years and more.
In territory of Meganesia more some species of ostrich kangaroos still:
Dwarf ostrich kangaroo (Theriostruthio nanus) lives in the strip of dry savannas and semideserts to the west of Eyre Gulf. Its length does not exceed 150 cm including the tail, and growth of sitting animal is no higher than one meter. On the body of this animal there is a pale pattern of dense vertical strips which pass to more contrast cross-striped pattern on tail and rear legs. Such colouring of wool appears fine masking at life in high grass. This species differs in high speed – at the short distances dwarf ostrich kangaroo can reach the speed of more than 80 kms per hour. The female of this species can bring posterity two times per one year – in spring and autumn. This animal grazes on four legs only in thin and short grass. Usually dwarf ostrich kangaroos eat, biting off tops of high grasses during the movement.
Striped ostrich kangaroo (Theriostruthio zebratus) lives in rather damp district – in bushy savanna at the western coast of Eyre Gulf. It differs from common ostrich kangaroo in considerably smaller size (length of body is up to 3 meters) and darker colouring. On yellowish-brown skin of this animal brown vertical strips stretch. Due to such colouring grazed animals are poorly appreciable among grass and in light forest. These animals have also special feature of behaviour – during movement each animal from time to time makes almost vertical jumps of height up to 4 meters.
Forest ostrich kangaroo (Theriostruthio sylvestris) has the same size, as the previous species. It lives in light forests growing in river valleys at the east of Meganesia. Jaws of this animal are weaker and lengthened more, than at common ostrich kangaroo. It is connected to a diet of this animal – it eats leaves of undersized trees and bushes, and also large grasses. The body of this kangaroo has spotty colouring – reddish-brown with vertical white strips on back and shoulders. Also the throat and bottom part of head have white colouring. Ears of this animal are rounded and have smaller size, rather than at species living in plain district.

Mirriuula (Diablowallabia camelophoneus)
Order: Diprotodontia (Diprotodontia)
Family: Kangaroos (Macropodidae)

Habitat: Meganesia, mountains in the east, to the south up to Flinders Range; forests and bush.

Picture by Carlos Pizcueta (Electreel)

The majority of kangaroo species represents herbivores of plains, bush and mountains. But it is not only ecological niche which these animals could occupy. The species of carnivorous kangaroo rats Ekaltadeta ima weight about 15 kgs, and also one more predatory kangaroo, Propleopus oscillans lived in the past in territory of Australia. In human epoch some wallabies differed in propensity to zoophagy. After extinction of placentary predators because of epizooties various species of marsupials occupied an ecological niche of carnivores during Neocene with different degrees of success. The small naked-breasted kangaroo, scavenger kangaroo rat (Harpotorous microraptor), lives in semideserts of Meganesia, eating carrion and the rests of prey of large predatory reptiles. The result of other attempt of kangaroos to develop predatoriness is mirriuula, the descendant of mountain wallaby (Petrogale) living in mountain areas of Meganesia.
Mirriuula is named after mythical demonic dog from folklore of Australian aborigenes, and quite justifies this name. It is a furious kangaroo weighting about 100 kgs, with flexible torso and long fluffy tail serving for balance. It is a predator eating birds, herbivorous kangaroos and mountain camelopes.
Mirriuula is not too similar to usual kangaroos by its constitution. It has rather short hind legs, and rather seldom rears on them. The mode of its movement is galloping jumping and true gallop. Mirriuula moves only on hind legs very seldom – usually it does it, attacking prey. At this time its forepaws are free, and mirriuula seizes prey by them. Mirriuula can run quickly both on short, and on long distances, but on open district or in foothills it frequently conflicts with other marsupial predators. But in mountains this species is out of competition. It gets big advantage in hilly terrain over marsupial jaguar and marsupial panther, surpassing them in dexterity. Besides these predators are more heat-loving and prefer not to come into mountains. And mirriuula is able to chase prey on hillsides; it arranges ambushes on tracks and frequently hunts in mountain forests and among thickets of undersized eucalypti. Colouring of wool of the mirriuula helps it to remain unnoticed. The basic background of colouring is brownish-grey, darker on head and paws. Tail is light grey, and its tip is almost white. On back of animal there are some longitudinal lines of dark spots.
Having long and strong limbs and hard bent claws, mirriuula can easily catch up and kill the goat-sized prey. It snatches on prey and brings it down on the ground with the help of strong forepaws, and then tears its throat by long pointed incisors slightly directed forward and closed, as a nipper. With the help of incisors this predator can easily bite through neck of prey. In strong jaws cutting molars with jagged edge and peaked molars easily cracking bones and tearing meat from them grow.
The muzzle of animal resembles cat's one a little – it is short and high, with large mobile ears. In nasal cavity of animal the olfactory epithelium forms many plicas; therefore sense of smell of this animal is very keen.
This is solitary animal strictly protecting its territory. At the territory of mirriuula there are some shelters, one of which is used constantly, and others are temporary; animal spends night in them, when eats large prey left near them.
At the territory of Meganesia smaller relative of mirriuula lives – fox wallaby (Diablowallabia omnivorodentus). This species inhabits plains overgrown with high grass, where it builds shelter representing deep hole. It hunts or traps in ambush small vertebrates, eats insects, digs out grubs, nutritious stalks and tubers of plants. It can run very quickly – as quickly, as its large relative. This animal has larger ears resembling ears of fennec fox – it is the adaptation for heat emitting. The wool of fox wallaby is colored yellowish-grey with several longitudinal lines of brown spots.

These species of animals were discovered by Tim Morris, Adelaide, Australia.

Mammoth kangaroo (Marsupimammuthus hirtus)
Order: Diprotodontia (Diprotodontia)
Family: Kangaroos (Macropodidae)

Habitat: mountains of the Great Dividing Range.
Kangaroos belong to the most successful marsupials of Australia and New Guinea. So it was before the human arrival, and so it remained after the extinction of the mankind. Of course, the family lost rare and narrow-area species during the anthropogenic crisis and the subsequent aridization of Australia during the Ice Age, as well as due to competition with descendants of placental mammals introduced by humans. For all that kangaroos survived and remained an ubiquitous group of large marsupials in Australia. Among them was the brush-tailed rock-wallaby (Petrogale penicillata), a small population of which managed to survive in the mountains. Its descendants were quite numerous, and occupied a variety of ecological niches, including those of predators. The largest of the descendants of this species is the mammoth kangaroo, a specialized inhabitant of the highlands (another descendant of this species thrives on the Hawaiian Islands).
The height of this beast in a bipedal position is 2.3 meters, length is 2.5 m, and weight is up to 182 kg. The wool color is brown, less often dark gray or rusty-red. The wool is long and resembles felt. This feature of their appearance, as well as the shape of their heads and their vocalization, makes them look slightly like the Baudet du Poitou donkey breed, a domestic animal of the human era. This animal mainly inhabits alpine meadows, mountain forests and valleys, where it is quite cool, and rarely descends into the hot foothills. It is a massive and slow animal; it hops rarely and reluctantly, preferring a slow “galloping” on four legs. Mammoth kangaroo feeds on branches and leaves, supplementing its diet with invertebrates and carrion. Occasionally, an animal tramples to death a reptile or a small mammal no bigger than a rabbit, and eats its prey. In winter, when snow falls on the peaks of the mountains, part of the population migrates down into valleys and forests. At this time, and even during the dispersal of young animals, some individuals are found in the foothills on both sides of the ridge, but they do not stay there for long and quickly move to areas of favorable climate. Young animals tolerate heat more easily; adults prefer to live in cooler highlands and are not inclined to change their place of residence. Mammoth kangaroo fights off its enemies, predatory marsupials, with kicks and punches of its front paws armed with sharp claws, and occasionally bites them.
The mating season takes place in spring, in September and October. Being ready to breed, female emits a special scent that males find her by. Males fight for females using clawed front paws and kicking with their hind legs. But the mating itself is quite rough – the male simply forces the female to obey, biting her on the withers and pushing her. Pregnancy lasts 6 weeks. Before giving birth, the female secludes herself and licks her brooding pouch clean. She gives birth to 4-5 underdeveloped joeys, which immediately crawl into the pouch. Of the entire brood, only 2 joeys survive, which manage to attach themselves to female’s nipples. Ten-month-old joeys venture out of the pouch for the first time, but at the first sign of danger they hide in it again. By this time, they begin to pass to adult food; at one year of age, they feed on grass (at this time the female is ready to give birth to a new brood), at the beginning of the second year of life they are completely independent. By the age of 3, the mammoth kangaroo is ready to breed. Life expectancy is up to 50 years.

Bladdernose Kangaroo (Rhinoroo desertus)
Order: Diprotodontia (Diprotodontia)
Family: Trunked Kangaroos (Nasalotheriidae)

Habitat: Desert of western Meganesia.

Picture by Alexander Smyslov

Australia is characterised in the age of man by arid deserts, this was not always typical of Australia. In the Neocene, Meganesia has parts that are similarly desrtified, and creatures living there have unique adaptations. The Bladdernose Kangaroo is a very distinctive form, seemingly comical in appearance, with swollen red nose.
This kangaroo is small at 20-25 Kilograms, and reaching a height of 70 centimeters at the hips. It’s sleek fur is a dusty cream colour with white underparts, this helps to keep the animal from overheating. Certain areas of high bloodlflow, thighs, and chest are bald and pinkish for heat dissipation, which can be licked to aid cooling. It has powerful forelimbs that are long, with large hands for grasping food, and its hindlimbs are about half again as long, with long feet. This kangaroo typically moves on all fours when foraging, but is able to hop at high speeds to escape danger. It has a short-compact torso, and a short neck ending in a large head, and a long tail.
The head is short and blocky, and the snout is a large inflatable sac that is round and swollen (by this feature it resembles saiga or hooded seal). This sac is infused with blood-vessels, and helps to cool the animal as it breathes, it can be flushed with blood, as can other bald spots, to help the animal cool. This sac is also a resonating chamber for producing loud calls, and can be inflated during the mating display. Call is typically short and loud nasal bark, but breeding calls are very loud prolonged roar.
Bladdernose Kangaroo feeds on desert herbs, grasses and flowers, as well as digging up roots and tubers and eating small desert fruits, it is completely herbivorous.
Breeding season is always during high productivity and rainfall, normally in the winter or spring. Males produce loud roaring calls to attract females, males generally have their own territory in which to attract a harem. Females congregate with males producing loudest call. During mating ritual, male inflates nasal sack considerably, resmbling baloon. During this display the sack is bright pink from circulation.
Female produces one cub that becomes mobile during the flush of spring growth, and suckles for 3 months. Lifespan is typically 20-30 years.

This species of mammals was discovered by Tim Morris, Adelaide, Australia.

Forest Probo (Probosciroo sylvanus)
Order: Diprotodontia (Diprotodontia)
Family: Trunked Kangaroos (Nasalotheriidae)

Habitat: Rainforests and Woods of northern Meganesia
During the age of man, kangaroos remained successful despite human influence.
With the extinction of mankind and the advent of the neocene, kangaroos competed successfully with the surviving introduced domestic herbivores. Camels produced numerous forms, and pigs became more specialised towards herbivory. Eventually, kangaroos produced omnivorous and carnivorous forms, which competed sucessfully with their placental counterparts.
The Forest Probo is descended from small omnivorous rat-kangaroos of the human age, such creatures were successful foragers. This animal has become much larger than it’s ancestor, becoming as heavy as a medium sized pig, at 40-60 kilograms.
It is 1.4 meters tall at the hips, and is usually bent over close to the ground to forage. It has a thickset body and a long tail; colored blackish brown with creamy underparts and a white dorsal stripe, fur is coarse generally. The forelimbs are long and powerfully built with large claws for digging, hind legs are only slightly longer with pointed claws, it moves mainly on all fours, only hopping when it needs to move quickly.
Its head is long-snouted, with a large thick horny pad on the upper side for digging with, its ears are long. The nose terminates in a moveable proboscis 20 centimetres long that has a flattened knob at its tip; this knob is very sensitive and can be used to pass food to the mouth.
This creature constantly forages in the leaf litter, moving earth with its snout similarly to a pig, but with the addition of a manipulative trunk.
When heavily pushing earth with it's nasal pad, it tucks it's trunk close to its mouth, however, the trunk can also move litter and overturn small stones. More extensive digging can be done with the claws.
The diet of this animal is as varied as that of a swine, fruit, roots, seeds, buds and shoots are consumed, and the animal voraciously raids nests of ground birds. Also small vertebrates, any insect or grub, and some carrion. It’s teeth have large cusps for crushing, and the premolars have a large shearing edge for cutting.
Animal vocalises with nasal squeals and coughs produced by trunk.
It is generally solitary, but mates all year long, to take advantage of any fortuitous encounters with the opposite sex. The female has a distinct musky aroma to alert potential suitors. The mating ritual consists of mock fighting and kicking up wood litter by paws. Female produces one cub, which crawls from the cloaca to the pouch. Babies leave the pouch by 3 months, but still use it for safety, and weans by 8 months, during which a new cub will be developing.
Young are colored more pale than their parents, but the colors become dark by one year of age. Lifespan is generally 25-30 years.
Similar relative, the Bush Probo (Probosciroo porcinus) is found in the forest and bush of southeastern Meganesia, including the mountain forests of the Great Dividing Range and the forested Murray River valleys. Differs mainly by longer legs, and lighter, dark grey coloration, the proboscis is shorter and possesses a square tip. Diet is more tolerant to dry, tough forage such as twigs.

Long Snouted Kangaroo (Dolichoops nasalis)
Order: Diprotodontia (Diprotodontia)
Family: Trunked Kangaroos (Nasalotheriidae)

Habitat: savannah and semidesert of central Meganesia
Occasionally during evolution in any animal group, new features distinguish an animal group, becoming a new taxonomic grouping. The Trunked kangaroo group has produced many different forms during the neocene. Evolution has been versatile, with large omnivorous forms and also numerous herbivores. Example is the long-snouted kangaroo.
This kangaroo is moderate in size, being 1 meter tall and weighing 30 kilograms.
This animal is sandy colored with soft, smooth fur, dusty white underparts and a black dorsal stripe, the hands, feet and face are pale. Its forelimbs are long and powerful, with bald patches along the inside which it licks to keep cool; the paws are large and have long claws for digging. The tail is long and its hindlimbs are of medium length, with long feet.
Ears are large, almost like a rabbit, and the head is long and low, recalling a horse.
There is a well developed muscular upper lip and nose which forms a swelling, this is very flexible and comes to a rounded tip, like a horse. The nasal cavity is enlarged, and the nostrils can be closed.
This animal feeds on roots, tubers, some grasses, herbs, and soft foliage, but will also eat insects. It forages bent over, close to the ground, moving generally by a slow bounding motion on all fours. It stands up periodically to sense any danger, but large ears and sensitive nose constantly provide early warning system while foraging. When forced to flee, it can either bound like a rabbit, or at higher speeds hop very quickly. These animals are generally found in small groups of 2 or three, which grow in number when breeding.
Mating occures in spring and winter, during higher producticity and rainfall. Males will fight over females using clawed hands and kicking feet. Females produce one cub which comes about in the typical marsupial fashion. Able to leave the pouch at 4 months, but will continue to use it as refuge, and to suckle, until 1 year, when another cub will have started to grow and suckle on the second teat.
Vocalisations are nasal cough or loud resonant sneeze. Lifespan is typically 30-35 years.

This species of mammals was discovered by Tim Morris, Adelaide, Australia.

Elephant-Kangaroo (Marsupielephas proboscoides)
Order: Diprotodontia (Diprotodontia)
Family: Trunk Kangaroos (Nasalotheriidae)

Habitat: tropical rainforest and gallery forest of Northern Meganesia, occasionally ranges into bushland or treed savannah.

Picture by Amplion

Evolution is characterized during stages of disaster by a rapid increase in size in a recovering ecosystem. Primitive hoofed animals quickly became as large as bears after the extinction of the dinosaurs, reptiles became as large as crocodiles quickly after the Permian extinction, and modern animals quickly became larger in the abscence of competitors, see the feral cats of anthropocene Australia. And thus, the evolution of the trunk kangaroos in the early Neocene is characterized by the Elephant Kangaroo. Most trunked kangaroos are relatively small or medium-sized, but the bountiful jungle of northern Meganesia provided an opportunity for a giant of the group.
Unlike its relatives, it is a leaf eater, reaching high into the trees to gather food. The teeth are high crowned and ridged, like those of a tapir or the extinct deinothere. 80 percent of its diet is leaves and bark, 10 percent is fruit, and the other 10 percent is rare animal forage. It will still eat animal matter on occasion like its ancestors. Still having a slicing premolar, it will rarely consume the eggs of ground birds, eat large beetles or stick insects, and scavenge flesh from the kills of marsupial panthers and the yagil. It has been known to eat ejected pouch young from the ground.
This creature by far surpasses any present kangaroo in size and stature, weighing up to 800 kilograms. It is no longer able to hop, it can only bound slowly and clumsily, recalling dinosaur. Its head is of medium length, deep and massive, with a relatively long snout, ending in a trunk that is 1.3 meters long. Its pelage is made of short, woolly hair. Its color recalls the Malayan tapir, with a large white saddle on a black background, it also a white facial “mask” and a white dorsal stripe, characteristic of its group, with white “socks” on hands and feet. Its arms are somewhat like that of a ground sloth, only less thick-boned, the claws are very long for pulling down branches, the longest claw is 20cm long. It has a fairly long, barrel chest and a short “humped” neck with thick shoulders. With wide hips and massive legs it can carry large, well developed joeys, its thigh is still relatively long, but its foot is short and flat, with massive “hooved” toes. The tail is fairly long and thick, with a white tip. By many features it is analogous the the long extinct Palorchestes, including a long, elephant-like trunk. It stands 2 meters tall at rest, which is bent forward. At a rearing height, it reaches 4 meters from the head to the ground, but due to its proboscis it can reach even higher. The trunk ends in a “finger”, not unlike those of the elephant of human era.
The mating season falls at the start of monsoon season, when they migrate to upland areas or clearings to court. The males make characteristic braying and trumpeting noises, accompanied by deep grunts and clicks, to attract a harem of females. If a dispute breaks out between males, it is settled by displays of physical strength, pulling down branches and biting them apart, throwing them away. Males do not risk physical harm due to their long sensitive noses. Babies are born at the end of the monsoon season, allowing enough time to develop into large joeys the size of small children. They defend their young viciously, lashing out with the forelimbs and biting, as they will also defend themselves alone using this method. The legs are too degenerate for large kicks.
Lifespan can reach 20-40 years, large adults have no predators except in times of drought when marsupial panther can hunt cooperatively.

This mammal species was discovered by Timothy Donald Morris, Adelaide, Australia.

Nagual (Tatu nagual)
Order: Edentates (Edentata)
Family: Armadilloes (Dasypodidae)

Habitat: North America, the south of prairies and the north of Mexican Desert.

Picture by Simon, colorization by Biolog

Initial picture by Simon

Nine-banded armadillo (Dasypus novemcinctus) alongside with opossum (Didelphis) and American porcupines (Erethizon) was one of the most successful descendants of South American fauna settled to the north in time of “Great Interchange” in Plio-Pleistocene. In human epoch this species had overcome Mexican plateau and was settled rather far to the north, having successfully mastered the south of the United States of America. During the ice age at the boundary of Holocene and Neocene armadilloes among other thermophilic animals had receded to the south, but with the subsequent warming they have returned to former positions again.
Nagual, the large species of armadilloes, lives at the southern border of prairies where the grassy vegetation is gradually replaced by water-stocking succulents and deciduous prickly bushes. It is large enough representative of family: its length is about 130 cm, and weight reaches 100 kg and more. The big size of animal is one of ways of survival in desert: the large animal has the big stocks of water in organism, and the strong armour protects not only from enemies, but also from the hot sun. At the north of the area nagual leads a day time habit of life, but at the south, in deserts of Mexico, activity is displaced to night time. It is also a way to avoid overheat and losses of water.
The armour of animal consists of two strong plates – forward and back ones – and between them some belts of cornificated skin with elastic sites between them are located. Under armour there is a layer of fat which is the heat insulator. As against the ancestor, nagual is not able to turn off in ball. Being attacked by predator, animal simply lays on the ground, having turned up under armour head and thick short tail. Because of large weight it is difficult to turn it, but if predator manages to do it, animal protects itself, sharply waving forepaws armed with sharp claws. The bottom part of animal body is covered with rough yellowish wool. Armour is colored bright yellow with grayish shade.
The head of animal is covered with strong corneous plate with skin ossifications which jut out on plate surface like rounded outgrowths. Eyes are small – nagual has bad sense of sight. Animal has mobile rounded ears which are penetrated with blood vessels and partly help to radiate the surplus of heat. Muzzle of nagual is short and triangular; teeth are numerous and have sharp cutting edge. They are closed in such a manner that edges of upper and lower teeth are constantly erased against each other. On teeth of upper jaw cutting edge is external, on lower jaw internal. Despite of size and slowness nagual is zoophagous species. It willingly eats carrion searching it by smell. Nagual is frequently fed with the rests of prey of local predators. Due to massive armour this animal does not pay attention to attempts of predator to protect the prey. Furthermore nagual eats medium-sized vertebrates and occasionally feeds on underground and sapful parts of plants, especially during the drought season.
Forepaws of nagual are perfectly adapted to digging. The third and fourth fingers are armed with huge claws – about 7 cm thick and up to 18 – 20 cm long. On scapulae ledges and crests to which strong muscles attach are advanced. Nagual easily moves the stones comparable in weight to the animal and can dig and throw out on ground surface up to half of cubic metre of the ground in some minutes. Defending itself against enemies, the animal drops to the ground and sticks claws into it deeply. In that case it is very difficult to turn nagual upside down. But if the predator had made it, the animal defends, making sharp attacks by claws. If it succeeds to grasp a predator, this armadillo seizes it in death grip and can easily strangle it or break its ribs. Therefore, when nagual appears near prey, lucky hunters prefer not to pay attention to this one.
The sexual dimorphism at this species is not expressed. Pregnancy is long because of latent stage: it proceeds till about 11 months, and cubs always are born in favorable season. Up to 10 cubs may be born; they have the same gender because develop from one initial ovocyte. Newborn armadilloes have opened eyes and are covered with soft leathery armour. In some hours after birth they are already capable to walk, and in same time the armour hardens quickly. Young animals remain with mother within 8 months. They reach sexual maturity in 4 years.

The idea about existence of this species of mammals is proposed by Nick, the forum member.

Aquatic armadillo (Hydrotatu potamophilus)
Order: Edentates (Edentata)
Family: Armadilloes (Dasypodidae)

Habitat: southern coast of North America: Florida, deltas of rivers at the coast of gulf of Mexico.

Picture by Alexander Smyslov

Armadilloes were one of groups of South American mammals managed to overcome isthmus of Panama and colonized North America successfully. In human epoch nine-banded armadillo (Dasypus novemcinctus) had moved far to the north, having overcome Mexican plateau, and had settled in southern extremities of North American prairies. In ice age armadilloes had been thrusted back far to the south, and along coast of gulf of Mexico only tiny relic populations of these animals remained. In such populations speciation and accumulation of new features passed roughly, and at the ending of ice age the southern part of North America had been inhabited with some species of armadilloes differing in shape and in habit of life. Some of them had died out subsequently, and others managed to fix in habitats for a long time, and their descendants make a part of Neocene fauna of North America.
In tropical areas of North America where various freshwater reservoirs are present, one species of armadillos lives, which had mastered a habit of life unusual to these animals – the aquatic armadillo. This animal is about half meter long including tail. By its shape it differs from other armadilloes only a little – its body on back and sides is covered with armour divided to thoracal and lumbar shields. Between them some (usually 6 to 8) narrow belts lay, permitting a body of animal to be bent. The armour of this animal, however, is much thinner, rather than at ground species. Tail of aquatic armadillo is of oval outlines, short and wide. Head from above is covered with corneous plate. Bottom part of body is covered with thin rough wool. This animal has dark colouring – reddish-brown with lighter edges of thoracal and lumbar shields.
Paws of aquatic armadillo are perfectly adapted to movement on fenny ground – between fingers and toes there are skin crosspieces increasing the support area and interfering with immersing of animal in marsh; also it helps in swimming. On forepaws strong claws are advanced. They are rather thinner, than at ground species which should dig firm deserted ground. With the help of claws aquatic armadillo digs from silt rhizomes and tubers of water plants making a part of its diet and also digs holes in riverbanks and among roots of trees.
Ears of this animal are short and mobile. In the basis of ear there is a skin valve which closes ear duct when animal dives. Aquatic armadillo orientates itself under water freely with the help of sight – it has rather large eyes. But in muddy water it orientates itself and searches for a forage by means of touch: it also has mobile lengthened snout richly supplied with receptors. By means of snout it finds out food of animal origin – worms, crayfishes, snails and larvae of insects. Animal and vegetative food in its diet is present approximately fifty-fifty.
Aquatic armadillo is active mainly in twilight, in the morning and in the evening. In hottest time of day it falls asleep in the hole dug out in a place where danger to be flooded at rising of water lavel to be minimal. This is very mobile animal able to run fast in underbrush or among thickets of reed in case of need. It is good swimmer due to the layer of hypodermic fat which serves as a float, and dives without any efforts due to rather big density. This armadillo can stay under water till about five minutes.
Breeding of this mammal is not dated for the certain season – the posterity of this species may be observed in nature the year round, and the female can bring posterity up to two times for one year. After the pregnancy continuing about three months, the female gives rise to from four up to six cubs – they always are enzygotic twins. They are advanced well enough and at one week age they do not concede to adult individuals in swimming ability. Young animals can only dive no longer than for one minute. They remain with mother till about five weeks and then start to lead independent life. Because of too short intestines the young growth eats food of animal origin mainly. At the age of 16 months young animals become sexually mature; life expectancy is about 10-12 years.

Spiny, or predatory armadillo (Echinotatu spinifer)
Order: Edentates (Edentata)
Family: Armadillos (Dasypodidae)

Habitat: Pampas of South America.

Picture by Lambert

In human epoch, armadillos did not suffer as seriously as other edentates. Although hunting and plowing of the pampas killed some species of these animals, armadillos survived and achieved evolutionary success, unlike sloths and anteaters. They have become more diverse in size and even occupied new ecological niches, turning into specialized forms. The North American nagual (Tatu nagual) has even passed to a large-sized class, and the South American donkey armadillo (Dromarmadillo asellinus) has occupied the ecological niche of a scavenger. Spiny armadillo is a descendant of the screaming hairy armadillo (Chaetophractus vellerosus) of the Holocene epoch, which turned into a predator.
It is a medium–sized mammal: body length is 52-57 cm; weight is 6-6.5 kg. Males tend to be slightly heavier than females. This animal has a narrow head of triangular shape and small movable ears. Tail is short and wide, with hard armor plates. Hair that covered its ancestor’s carapace modified into pointed spikes, providing additional protection. The body color is light brown, the color of the spikes varies from almost white to black; their length is 3-5 cm. Fingers are equipped with powerful flat claws, adapted for digging and especially well developed on the front paws. Each animal independently digs out a deep hole ending with a living chamber and having 1-2 additional exits. Spiny armadillo is a nocturnal animal, emerging from its burrow at sunset. It feeds on small rodents (sometimes digging them out of their burrows), reptiles and amphibians, eats birds sleeping on the ground and ravages their nests. This species does not disdain carrion and scraps of predators’ prey, and occasionally eats invertebrates. At dawn, it returns to one of its burrows, or digs a new one. Each individual has a specific territory, which it inspects every few days in search of food. The animal leads a solitary lifestyle and marks the boundaries of the territory with droppings and urine.
Due to the peculiarities of the animal’s diet, the teeth turned into approximately uniform cutting blades, capable of scraping bones and cutting the meat of prey. Caught out of its hiding place, the animal tries to hit the enemy with claws of its front paws and bites.
Mating season takes place from November to January. Female gives birth to 4-6 cubs. In half of the cases, all her cubs develop from a single zygote. For the first 3 months, the female feeds her cubs with milk, hiding them in her burrow. At this time, the cubs can leave the burrow and search for small prey on their own, but in the morning they return to the shelter. Grown-up juveniles begin to hunt with their mother. At the age of 7 months, young spiny armadillos are already independent, reaching sexual maturity at the age of 1 year. Life expectancy is about 23 years.

This mammal species was discovered by Nick, the forum member.

Digging armadillo (Postpichisiego trachycephalus)
Order: Edentates (Edentata)
Family: Digging armadilloes (Armotalpidae)

Habitat: South America, pampas and light forests from warm temperate up to tropical zone.

Picture by Alexander Smyslov

In human epoch in South America mammals constantly leading digging habit of life (the analogues of moles of Holarctic region) were absent. At the same time in territory of this continent there were many kinds of burrowing rodents and armadilloes. Fairy armadillo (Chlamydophorus truncatus), or pichisiego died out in human epoch had led the way of life closest to moles.
In Neocene of South America armadilloes had taken a significant place in fauna. They successfully compete to rodents, and one species became a large scavenger. Among Neocene armadilloes one species which conducts practically completely underground way of life had evolved. This small animal is named digging armadillo.
Digging armadillo is deeply adapted to a underground habit of life. The body of animal is about 25 cm long. It has almost cylindrical shape and is covered with strong armour. In the middle of trunk the armour of animal forms five belts connected by elastic skin. These belts allow digging armadillo to turn off in ball and to turn round in its own tunnels. Tail of this animal is short and wide in the basis and has triangular outlines. Edges of corneous belts of tail form thick strong prickles. Resting them in floor and walls of hole, animal provides a reliable support at digging to itself.
At this animal there are short limbs. Hinder legs of digging armadillo are rather weak and three-toed. Forepaws are wide and muscled, armed with three huge claws (the largest claw on middle finger reaches length of 4 cm, claws on third finger and forefinger are shorter). During the digging animal supports on prickles on edges of tail, and rakes ground out by claws of forepaws. Friable ground is raked back by hind legs. When the rather large amount of it is gathered, digging armadillo turns tail under stomach, and moves back, pushing ground to the exit of hole. On the ground surface this animal is very cautious, and the predator practically can not creep to it imperceptibly. Digging armadillo feels keenly vibrations of ground, and feels approaching of large animals how they will see it.
Digging armadillo is practically blind. Its eyes are shifted in the bottom part of head and are very small. In them there is no crystalline lens, and the animal can distinguish light from darkness only. The head of digging armadillo is covered with thick corneous plate in which basis thick skull bones lay. Ears of animal are very short, protected from ground by rigid bristles. The forepart of muzzle is protected by “visor” of corneous plate, and nostrils are supplied with muscles permitting them to close. At digging of friable and dry ground animal can hold the breath till 1-2 minutes. Due to such features of anatomy the animal is able not only to dig tunnels but also to swim. Digging armadillo can successfully swim across small rivers, being guided on smell of air above water. During the swimming it rows by forepaws, and turns rear legs in sides, and they serve for balance.
Digging armadillo eats various ground invertebrates, but the vegetative food – roots and tubers – makes about 20 % of its diet. This animal prefers to settle in areas with small amount of wood vegetation. Digging armadillo often builds the common systems of holes with some local rodents, but such neighbourhood not always passes without conflicts – digging armadilloes willingly eat newborn rodents.
In southern regions of area this animal runs into not deep winter dormation, does not dig new tunnels and does not leave on ground surface.
In the beginning of spring at digging armadilloes the courtship season begins. Male is larger, than female, and behaves more aggressively. It searches in tunnels of females ready to breeding, pairs with them and does not accept participation in care of posterity any more. In 7 weeks after pairing in deep hole the female gives rise to posterity – 4 cubs which always are enzygotic twins. While they are small, the female often comes back to feed them, but since the third week of life cubs can follow freely the female in tunnels and gradually pass to diet of adult animals. They become sexually mature at the age of half-year.

Aotearoan Ridgeback Hedgehog (Notoechinus vorax)
Order: Insectivores (Insectivora)
Family: Hedgehogs (Erinaceidae)

Habitat: North Island of New Zealand, woods, scrub and sub-tropical forest.
Species introduced by Englishmen to acclimatize themselves to the country of New Zealand were very varied, including many European species, among them, the Common Hedgehog (Erinaceus europaeus). This species leaves various insectivorous descendants in Neocene New Zealand, but one form differs in being more generalized.
Being found in the forests of the North Island, this hedgehog is relatively large, about 45 centimetres long, its ability to curl up has reduced, and instead it has a distinct ridge of short, very sharp spines down its back and along its flanks. Reason for loss of defensive posture is also evident by this animals large head, relatively long with sharp front teeth. Front claws are relatively long and straight, hind and fore legs are longer than its ancestor, giving it an upright shape more resembling an oversized, tail-less rat. Coloration can vary from a straw-brown colour to a reddish brown, but always with darker spots, each spine is yellow with a black tip, nose and feet are black.
It is an omnivore with some preference for animal food, large insects, worms, slugs and snails, as well as small rodents, frogs, lizards and young rabbits, and the eggs of ground-nesting birds. Vegetable food includes fallen fruit, large seeds and nuts, as well as softer root vegetables.
It is mostly solitary, being active during twilight and early evening. Sense of smell and hearing is very keen, and it is by these that it usually finds its food, eyesight is relatively poor. When attacked by a predator, it will arch its back and produce a yarring chirr; if this fails it will bite fiercely, or flee. This animal breeds in the summer, from November until mid January, males will compete for the attention of females and follow them around ardently until they submit to an overture of nuzzling, and males may mate with multiple females. Mating is brief, but can occur multiple times. The female raises the litter alone, which generally numbers 4 or 5; the young are born blind and only grow their prickles later. Weaning occurs at about 6 weeks, sexual maturity is reached at one year, and lifespan is up to 10 years but usually less.

This species of mammals was discovered by Timothy Donald Morris, Adelaide, Australia.

Azorean tree hedgehog (Dendrogalerix scandens)
Order: Hedgehogs (Erinaceomorpha)
Family: Hedgehogs (Erinaceidae)

Habitat: New Azora, lowland and mountain woods.

Picture by Alexander Smyslov

Usually island ecosystems differ in poverty in comparison with continental ones. Few species can get on islands and survive in conditions of isolation. Island ecosystems differ in vulnerability, and strongly suffer from introduction of new species. Newly appeared species change a course of evolution of other inhabitants of ecosystem because actually they are the new factor of environment for native ones. But the introduced species change not less, than others, having got in new conditions.
On New Azora Island the majority of mammalian species is descendants of species introduced by people. The special species of insectivores, the Azorean tree hedgehog – belongs to them. It is tree-climbing species of animals, the descendant of European hedgehog (Erinaceus europaeus) introduced in historical epoch. Earlier unite species had given two branches of descendants. The massive line of ground animals is presented by large azogalerix, and small descendants of European hedgehog turned to tree-climbing species.
Change of way of life had resulted in strongly expressed difference of new species from ancestor in constitution and behaviour. Azorean tree hedgehog is not able to turn in ball, and the hypodermic muscles characteristic for ancestor became very weak at it. The body of this animal is still covered with the pointed spikes serving for self-defense. In case of danger the animal nestles against bark of tree and exposes towards to the enemy spikes which can rise and fall with the help of special muscles in the basis of each spike.
In connection with tree-climbing habit of life at this animal there are relatively larger paws, than at ground hedgehog. Azorean tree hedgehog dexterously and quickly swarms up trees, and confidently keeps even on vertical surface of tree trunk. Fingers at Azorean tree hedgehog are more mobile; with their help animal can cling even to thin twigs. Besides this mammal has one more adaptation permitting to keep on trees better. On the back side of paws at this hedgehog especially strong and thick, slightly bent spikes grow in line. With their help the hedgehog can cling to bark, swarming up tree trunk and branches.
Head at this animal is extended and flattened. The muzzle is extended in mobile proboscis with which help animal searches for forage. Ears at Azorean tree hedgehog are wide and mobile – it is necessary not only for search of prey, but also for more effective heat exchange in conditions of hot climate. At animal there is keen hearing due to which this hedgehog can hear noise of insect creeping on bark in night darkness. At this animal there is good night sight, but Azorean tree hedgehog distinguishes colors badly. The brain at this animal is small, and behaviour differs in primitiveness.
Azorean tree hedgehog occupies an ecological niche of small prosimians in ecosystem of this island. This is a solitary animal eating mainly small animals – insects, tree-climbing land crabs and nestlings of various birds. Due to ability to climb on trees this animal can attack colonies of fog swifts settling in cavities of trunks of large trees. Also Azorean tree hedgehog eats mushrooms and juicy soft fruits. Among mushrooms the animal chooses the most worm-eaten ones, and eats them along with larvae of insects settling in them. The poison accumulating in some mushrooms does not harm to it – at Azorean tree hedgehog there is strong immunity to poisons, inherited from ancestor.
Each individual occupies the certain territory which is marked by odorous secretions. Out of breeding season there are no constant shelters in territory of this little mammal. These animals meet only in period of pairing, and in another time protect the territory from relatives. The posterity at these hedgehogs is born two – three times per one year. In litter it may be up to 5 – 6 small, blind and helpless cubs. Before their birth the female searches for shelter in which it will raise cubs. Usually for this purpose it occupies hollows or old bird nests. If necessary the female can expel medium-sized birds from liked nests: it eats their laying or nestlings, and occupies the empty nest.
Young animals abandon nest at the age of about two months. At this time they already see well and able to climb on branches. The litter keeps near to the female till two next weeks, training in ways of getting of food. One-year-old animals already can bring posterity. Life expectancy of this mammal does not exceed 6 years.

Tchagrin(Aepierinaceus tchagrin)
Order: Hedgehogs (Erinaceomorpha)
Family: Hedgehogs (Erinaceidae)

Habitat: Balkans, South-Eastern Europe, south coast of Fourseas, Caucasian peninsula.

Picture by Alexander Smyslov

Early Neocene lacked various and diverse ecosystems; its’ ecosystems lacked big herbivores and carnivores. So the situation was a bit like early Paleocene when the representatives of different animal groups were having their “tryouts” of different environmental niches. That happened in Eurasia where nature was once under the especially strong influence of mankind. The representative of different species and orders were having their “tryouts’ for the ecological niche of big predator. During a few millions of years true predators from the Carnivora order had to co-exist with different predators representing insectivores and primates. Finally they retook their rightful places in ecosystem which were abandoned during the dominance of mankind, but some of the competitors are still there. In the northern European forests spinywolf (Erinalupus spinosus) lives, and the Mediterranean maquis is inhabited by jackal hedgehog (Erinalupus mediterraneus). The subtropical belt of Europe- Balcans, Asia Minor and Caucasus- are inhabited by another representative of the same family- huge hedgehog tchagrin.
That animal has more primitive features compared to its relatives. Tchagrin is a stocky animal, reminding badger in proportions. Body length is around 140 cm. The visible tail is absent, the head is relatively big, with long movable snout. The fur is grey with brown shades, lighter on the belly; around mouth the fur is white. Tchagrin has strong jaws with sharp teeth of carnivorous animal. But pursuing its prey isn’t one of strong sides of tchagrin: his limbs are relatively short (longer than those of badger but shorter than those of dog) and it’s plantigrade animal. So maximal speed of sprinting tchagrin is around 30 km\h.
Tchagrin has poor eyesight- it’s myopic. But the animal has keen sences of hearing and smell which help him to locate his prey and the sources of possible danger.
From its ancestors the animal has inherited another specific trait- among its fur on the back you can find 5 cm-long hard quills. Those cover upper part of the head, neck, shoulders and the middle of the back along the spine. Tchagrin lost the ability to roll itself up in the ball for protection cause he's too large to do that. But the large size gives him the possibility of active defence. While defending himself, tchagrin opens his mouth wide to demonstrate sharp teeth, and actively tries to bite its opponent or attack him with claws. Rudimentary muscles under skin allow the animal to lift the quills during the attack of predators. That’s a solitary animal who is very aggressive towards its own species outside of mating season. During the fight two tchagrins "box" with their heads while quills are up. During the courting in the mating season male pushes female to the bodyside with his head, quills are down.
The mating season of tchagrins starts early in the spring. The female, who is ready for the coupling, has specific strong musk smell that attracts males. One female can attract up to 5 males. They engage in strong rivalry, pushing the rivals away from desired female with their heads. Female doesn't care about her mate, so sometimes mating happens while the other males nearby are fighting. The winner walks behind the female on stretched legs, sniffing loudly and pushing the female with his head. Once the mating is over, the female sends males away from her.
The pregnancy is about 5 weeks long. The female makes the nest for her cubs from branches and ground. She makes a pile of the branches and digs something akin to dugout under it. The dug earth is thrown over the branches to make a cover from the rain and the wind. The brood (usually 3-5 cubs) is born naked and blind. The eyes open at the age of a week, and at the age of 6 weeks they leave the den together with their mother and start searching for the food with her. The maturity is reached at the age of 3 years, the life span of the species is 40-45 years.

Scaly hedgehog (Squamoechinus loricatus)
Order: Hedgehogs (Erinaceomorpha)
Family: Hedgehogs (Erinaceidae)

Habitat: Caucasian Peninsula, Asia Minor, Middle Asia to the east from Fourseas.

Picture by Alexander Smyslov

Small mammals had gone through epoch of anthropogenous pressure much better, than large ones. In the majority they had kept biological variety and had quickly restored their number after human disappearance. In Neocene among them species developed new features and strategies of survival had evolved.
One unusual species of insectivorous mammals lives in droughty areas in Western Asia to the south of Fourseas – it is scaly hedgehog. Hedgehogs are rather conservative group of mammals though occasionally among them freakish species evolve like fossil Deinogalerix or Neocene spinywolf; both species are large predators. But the majority of hedgehogs even in Neocene are presented by small animals eating insects and other invertebrates.
Scaly hedgehog is a small animal: the length of its body does not exceed 30 cm. Its constitution is typical for hedgehogs: massive trunk, short tail, unspecialized five-fingered and five-toed paws and large head on short neck. Living in hot areas this hedgehog is covered with thin wool of bright yellow color. Back, sides and the top part of head of this animal are spiny – it has inherited this feature from ancestors. But spikes have an unusual structure.
The part of spikes on sides and back is modified into wide scales which gradually transform to the ordinarly looking spikes kept only in forward part of head. Scales have light brown or straw colouring – it helps this animal to avoid overheat. But tips of scales are colored black that unmasks this animal on the background of landscape.
Scaly hedgehog is not afraid of predator attacks, but uses different protection tactics depending on the kind of attacker. If the attacking predator belongs to mammals, this hedgehog is curled off in ball. The scales skintight to each other, forming strong enough armour, and their pointed tips do not allow a predator to unwrap scaly hedgehog by teeth or by paws. Being under attack of reptiles swallowing prey entirely, scaly hedgehog, on the contrary, rises on paws and stretches scales in sides in order to seem larger. Thus black tips of scales are well appreciable on background of light colouring of animal, exaggerating its visual size. Thus hedgehog does not recede even if the reptile touches it with tongue – having convinced that it cannot be bitten, reptile does not continue the attack. Protecting itself against reptiles, this hedgehog turns head to them and rotates on the spot if the predator tries to go and to attack from side.
The diet of scaly hedgehog includes invertebrates (also poisonous ones), small vertebrates and occasionally berries of plants from which it gets needed moisture. This animal is capable to live for a long time without water, getting moisture from prey.
This species of animals is solitary one. Each hedgehog occupies the certain territory from which it expels all strangers. Only a female raising cubs has any constant shelter – usually it is the abandoned hole or crevice between stones. At this species the posterity is born in spring. In a litter there are 3 – 6 naked and blind cubs which grow spikes to the fifth day of life. At the age of 4 weeks the part of needles on back and sides drops out, but at their place at once scales start to grow. At six-week age young animals leave mother and lead independent life. At the age of 1 year they reach maturity. Life expectancy of scaly hedgehog does not exceed 10 years.

New Zealand hedgehog (Austroerinaceus myrmecophagus)
Order: Hedgehogs (Erinaceomorpha)
Family: Hedgehogs (Erinaceidae)

Habitat: New Zealand, forests of Northern Island in area of subtropical climate.

Picture by Alexander Smyslov

Before human arrival to New Zealand there were no mammals, except for flying and marine ones. People had introduced to these islands a plenty of mammals of various groups which had started to evolve after human disappearance, changing themselves and occupying new ecological niches. The descendant of European hedgehog introduced to New Zealand by people is New Zealand hedgehog, living like ecological analogue of anteater. By its appearance this hedgehog as if parodies the echidna of human epoch because of the muzzle extended to proboscis, long tongue and the forepaws specialized for digging.
New Zealand hedgehog is rather large animal in standards of insectivores: it grows up to 40 cm long and weighs about 800 grammes. All its back, back part of body, top half of sides and even forehead are covered with spikes, straighter and shorter than at echidna. Fur of New Zealand hedgehog is short, but dense, especially at individuals from southern parts of area. It is colored monotonous gray-brown color, but sometimes there are also lighter colored individuals and even partial albinos having white irregular-shaped spots scattered on body.
Forepaws of New Zealand hedgehog are partly specialized for digging holes of underground invertebrates and vertebrates, and resemble paws of American ground squirrels with long and powerful claws. Nevertheless, as against animals like echidna and American anteaters, these claws are not bent and do not prevent this hedgehog to walk on the ground. Hinder legs of hedgehog are considerably less specialized rather than forepaws, and are even a little bit longer. It gives this hedgehog a little bit humpbacked appearance and prevents it to curl in ball similarly to its ancestors. But ability to curl in ball is not too important any more for it as it can escape rather successfully from enemies, having dug in ground like echidna. But longer rear legs and powerful back permit New Zealand hedgehog to rise vertically, that help it to climb on small tree for ants or other invertebrates.
New Zealand hedgehogs live mainly on Northern Island of New Zealand plentifully overgrown with forest. There these hedgehogs efficiently dig forest litter in searches of ants, worms, bugs etc. pulling them out from underground holes by long tongues covered with sticky saliva. Sometimes they creep in underground tunnels of castle rabbits and can put some loss to young rabbit cubs before leaving to the surface. New Zealand hedgehog has still kept sharp enough and strong molars suitable for eating of animal like newborn rabbit cub, but adult rabbits can not be afraid of this hedgehog: they are too large and strong for this prickly animal. Nevertheless, they can make of nothing when hedgehog got in their “fortress” because to answer their attacks hedgehog turns spikes aside the opponent and it cannot neither be pushed away nor bitten.
More mountainous Southern Island is less inhabited by these hedgehogs and they live basically in lowlands, in bushy thickets along the rivers where there is lesser opportunity to meet ruacapangi – large flightless bird of rallid group which can punch through this hedgehog by long beak despite of its spikes, break it off by claws and peck off all edible parts from prickly skin. Besides there is larger amount of food for hedgehog in such places, rather than in drier high-mountainous areas of island.
The peak of activity of New Zealand hedgehog falls to night time when it walks across its territory and updates its borders with odorous marks. In the afternoon time hedgehogs sleep, having buried in the ground or in leaf layer except the moments when they feel the rain coming. These animals do not like rain, especially individuals from Southern Island and if they feel approaching thunder-storm, they immediately leave the shelters and search for places more protected from a rain without dependence from time.
The courtship period at New Zealand hedgehogs takes place in drier season, since May till July. At this time males actively court females, arranging competitions during which they “box” against contenders by prickly forehead. Approximately 5 weeks later females bring a litter of cubs, from 4 up to 6 ones in litter, but at the north it may be up to 7 – 8 ones. Cubs are born almost helpless and blind, but in one and a half month they turn quite independent, and at the third month of life leave mother.
Usual life expectancy of New Zealand hedgehog is about 5 – 6 years.

Mangys (Paramesechinus meles)
Order: Insectivores (Insectivora)
Family: Hedgehogs (Erinaceidae)

Habitat: Asian steppes.
Among insectivores, in particular hedgehogs, losses during human domination epoch were lower than in other animal groups. Solenodons became extinct, but the other families lost only a part of the species and managed to restore their former biodiversity, mainly due to their small size and short life cycle. Moreover, during the Ice Age, new forms of insectivores emerged, some of which survived to the Neocene. In the historical epoch, due to human activity, Daurian hedgehog spread widely, but in Neocene, its descendants persisted only in the steppes. One of them is mangys (the name means the Buryat evil spirit).
Body length is 60-65 cm; weight is up to 7 kg. Wool color varies from light sandy to dark brown. In its physique, beast resembles a stout badger. The forehead and sides are covered with spikes; they are less numerous on the back. Tail is very short; paws are plantigrade, equipped with claws. If necessary, the animal can swim and climb bushes and low trees.
The teeth are very sharp and cutting, with numerous pointed tubercles. Animal has poor eyesight, but excellent sense of smell and keen hearing. This animal defends itself from enemies with bites; passive protection by spikes is actually not used.
Mangys is a predator feeding primarily on rodents, amphibians and reptiles. He is able to bite a dwarf harelope, ravage a bird’s nest, eat carrion or pick up prey after larger predators. It can drive zibetonyx, mustelids or small felines away from prey, but is afraid of deinapers of any age, as they can eat this beast, despite its spikes. Fastidiousness in food partially reduces competition with the kermez, which feeds on close but smaller prey. Mangyses are solitary beasts expelling competitors from their territory of 300-400 hectares. In autumn, these animals get very fat and hibernate until spring, choosing a deep hole for wintering.
The breeding season begins in March. Males find females by a specific scent, which they begin to emit when ready for mating. The males’ fights at this time are accompanied by flank thrusts and growling. The cubs (3-5) are born 70 days later; female hides them in a wintering hole, expanding it and laying a litter. The cubs develop relatively slowly: they open eyes at the age of 38 days, but at the age of 3 months they are already feeding on their own, returning to the burrow only to spend the night. In autumn, on the eve of hibernation, all families break up. Mangyses become sexually mature in the second year of life, with a life expectancy of up to 15 years. Their natural enemies are deinapers, large owls and herons.

Anteater hedgehog (Angustiechinus myrmecoleon)
Order: Insectivores (Insectivora)
Family: Hedgehogs (Erinaceidae)

Habitat: steppes of the Three Rivers Land, the western coast of the Fourseas, the Balkans, the Caucasian Peninsula.
During the epoch of the drying up of the Mediterranean Sea and its transformation into a salty desert, the climate of southeastern Europe became increasingly harsh and arid. Hedgehogs living along the shores of the inland seas of Eurasia had to adapt to new conditions and change their way of life. One of the hedgehog species that lived in these extreme conditions became the ancestor of a peculiar Neocene species of these animals. Along the shores of Fourseas its descendant lives – anteater hedgehog, a specialized insect hunter. This mammal is slightly larger than its ancestors, inheriting many of the common features of hedgehogs – a stout body, the ability to curl up into a ball and numerous spikes growing on its back. But the specifics of the diet have left their mark on its appearance: it has evolved features more typical of South American anteaters of the human era. This animal has a very narrow elongated muzzle with a small mouth and a long sticky tongue, and large claws on its front paws, adapted for digging up anthills.
The ancestor of this hedgehog is long-eared hedgehog (Hemiechinus auritus) of the Holocene epoch, one of the most common animals of the dry steppes, semi-deserts and deserts of this region. During the time of drying up of the seas, climate change contributed to a decrease in competition and a reducing of the number of predators. When most of the insects left these territories or became extinct, the descendants of long-eared hedgehog adapted to feeding on ants as more accessible and abundant food.
The size of an adult is up to 35 cm, and the weight is up to one kilogram; the female is slightly smaller than the male. Ears, unlike its ancestor, became significantly smaller and equipped with an internal valve, a skin fold that tightly clogs the ear canal during insect hunting. Body is covered with long, coarse yellowish-brown hair, which protects it from the attacks of ants. On the back and sides, spikes grow, which have become about twice as long as the ancestor’s ones. Unlike its ancestor, this hedgehog is able to defend itself from enemies actively by hitting the claws of its front paws. But the main feature of this species is the shape of the muzzle, which has become long, with a small movable mouth containing a long sticky tongue capable of protruding 8-10 cm far from the mouth. Lower jaw is thin and weak, with reduced teeth: incisors and canines are very small, looking like pegs. Molars have cutting blades on their crowns.
Fingers are equipped with powerful flat claws adapted for digging up anthills and breaking rotten stumps. This species feeds mainly on ants and their larvae. In winter, in conditions of seasonal climate, anteater hedgehog hibernates in a deep hole, and in spring, when there are no ants yet, this hedgehog can use its claws to break rotten wood, diversifying its diet with small grubs of wood-boring beetles and larvae of other insects. This species is a solitary animal, zealously defending its feeding territory, the boundaries of which are marked with urine.
Its general habitats are dry steppes and semi-deserts, in which it adheres to river valleys and dewy ravines with patches of woody vegetation. In warmer seasons, this hedgehog does not build lairs and lives in temporary shelters under driftwood and fallen tree trunks. In autumn, it digs deep wintering holes, or occupies ready-made ones, often expelling their former inhabitants with blows of its claws. The animal stocks fat until autumn, and in early November it goes into hibernation, which lasts until March.
The hedgehog breeding season begins in the middle of spring, when the animals put on weight after hibernation. Males find females by scent, but after mating, the female drives the male away and breeds its offspring alone. Pregnancy lasts up to 4 weeks, and about five blind, helpless cubs are born. After a week, they open their eyes, and after another 10 days they start eating food of adult animals. Young animals live with their mother until about the middle of summer; later, the female’s maternal instinct fades, and she drives away the grown-up offspring. By the next spring, the young animals become fully mature. Life expectancy is usually no more than 5 years.

Aquatic moonrat (Potamogalerix piscator)
Order: Insectivores (Insectivora)
Family: Hedgehogs (Erinaceidae)

Habitat: Southeast Asia, freshwater reservoirs in tropical forest.
In the early Neocene, insectivores experienced a short-term but violent outbreak of adaptive radiation – the descendants of species that survived the era of the biological crisis began to make attempts to develop new ecological niches. In the tropics, among the surviving species were moonrats, or hairy hedgehogs. Some of their species became extinct, but the survivors evolved into new species and even made attempts to explore new habitats. One of these species is the aquatic moonrat, which migrated from the forest to rivers and wetlands. In addition to them, another group of aquatic insectivores exists in Asia – these are large aquatic shrews. But they live in cooler areas of the continent – in mountain rivers and north of the equatorial zone. In the tropics, they are replaced by aquatic moonrats.
Aquatic moonrat of Neocene is a descendant of the Holocene moonrat (Echinosorex gymnura). Compared with the ancestors, the size of this species has hardly changed: the body length is 30-40 cm, the tail is 20-25 cm, and the weight of an adult is 1.5-1.7 kg. The anatomy of this animal has pronounced features of adaptation to movement in water: along the sides, hands and feet are bordered by a fringe of bristly hair, which increases the swimming surface of the paws. The upper and lower sides of the feet and hands are hairless. Feet are elongated, which makes the animal’s gait on land somewhat awkward: aquatic moonrat walks, lifting its hind feet high. On its lower surface, tail has a comb-shaped keel formed of stiff elongated hairs. The ears almost do not protrude above the fur.
Hair covering, despite living in the tropics, is very thick, dense and water-repellent. Wool coloration is bicolor and sharply contrasting: back and head are black, blackish-brown or brown, sides and belly are white, gray or yellow-white, depending on the population. This species leads a semi-aquatic lifestyle. During their settling, young animals are found at some distance from water bodies, but always in rich habitats with an abundance of food.
This species swims and dives well, spending up to 12 minutes underwater. Like its terrestrial relatives, aquatic moonrat is zoophagous and feeds on invertebrates (insects, worms, mollusks), frogs, small fish, and fish eggs. However, it eats prey on the shore, or leaning out of the water. Prey is hunted with the help of vision; under water the animal actively digs up drowned leaves and thickets of aquatic plants, turns over driftwood and pieces of bark.
Aquatic moonrat is active mainly during the day, sleeping in a hole dug in the riverbank and camouflaged among the foliage of marsh plants. This species is solitary, only a female with cubs and animals of opposite sexes are found together. Animals of both sexes do not tolerate congeners of their own sex; when they meet, both animals sit on their hind legs and begin “boxing” with their forepaws. During intraspecific fights, teeth are not used, but aquatic moonrat protects itself from predators with bites.
When living in the tropics, the mating season is not expressed. At any time of the year, there are both ready-to-mate females and females with cubs in the habitats of this species. As a rule, a female has two litters per year. Pregnancy lasts about 40 days, and there are 2-3 cubs in a litter. Cubs are born blind and their eyes open only at the 12th day of life. At this time, the female hides them in a hole. At the age of 3 weeks, they already try to swim, and at the age of 1.5 months they hunt small invertebrates. At the age of 4 months, young aquatic moonrats are completely independent. In young animals, the light areas on the wool are smaller than in adults: there is only a spot on the throat and chest. Puberty comes at the age of 7-9 months (earlier in males). Life expectancy is up to 11 years, but usually less.

Ant-eating moonrat (Myrmigalerix dolichoglossa)
Order: Insectivores (Insectivora)
Family: Hedgehogs (Erinaceidae)

Habitat: Southeast Asia, Jakarta Coast and islands, including Kalimantan.
Having suffered during the human era, insectivores experienced a rebirth in the early Neocene. Due to a burst of adaptive radiation, they not only regained their diversity, but also occupied new ecological niches. So, sabre-toothed shrew turned into a predator, and other species became specialists – for example, wormtonguer and snailer from Africa. The Asian pishonia has become a semi-aquatic animal. A representative of another family, ant-eating moonrat, a descendant of Javan short-tailed gymnure (Hylomys suillus) of Holocene epoch, became a specialized myrmecophagus, outstripping the neighboring pangolins in the degree of adaptation.
Ant-eating moonrat is a small animal: the body length is 25-27 cm; the hairless inflexible tail is 15 cm long. The weight of an adult animal is 500 g; males are larger than females. The animal’s appearance has changed little since the human era: ant-eating moonrat resembles a large rat with brown, coarse fur, more like hog bristles. This animal has a short muzzle, but its tongue is long and flexible, protruding 10 cm far from its mouth. Mouth itself is small, and the lower jaw is weak and thin. Teeth are pointed and have many tops, being adapted to piercing and cutting insect cuticles. Incisors are spread apart, and there is a gap between them through which the tongue protrudes from the mouth.
Ant-eating moonrat feeds primarily on ants, digging up their nests and licking off the insects. Its pungent smell keeps the ants from attacking immediately. Sometimes the animal digs up and cracks the termite passages, but it cannot crack the termite mound itself. In addition to social insects, ant-eating moonrat can also eat other insects, but rarely and only small ones. It hunts mostly during the day. Swallowed insects are ground into a homogeneous mass by the muscular cornified walls of the stomach. It usually eats up to 1,500 insects per day, managing to examine several anthills. Ant-eating moonrat is very cautious, as it is hunted by birds, snakes and some lizards. Usually, an alarmed animal quickly runs away into the undergrowth, changing sharply its direction of movement, and hides in burrows or under tree roots.
Seasonality in the reproduction of this species is not expressed and at any time of the year a female with cubs may be met. The mating games of ant-eating moonrat are primitive and reduced to the chasing of the female by the male. After mating, the animals leave each other. Pregnancy lasts 65-70 days. Females give birth to two, less often three cubs. Lactation lasts about 2.5 weeks, and then the female feeds the cubs with half-digested insects from mouth to mouth for a while. At the age of 1.5 months, the cubs follow their mother, and at 4 months they are completely independent. At this time, the female is ready to reproduce again. She is able to give birth to up to 3 litters per year. Young animals mature sexually at 8 months, with a life expectancy of about 13 years. But most individuals die earlier in the stomachs of predators or from diseases.

Tiger or dwarf spinywolf (Erinalupus tigrillo)
Order: Insectivores (Insectivora)
Family: Spinywolves (Erinalupidae)

Habitat: endemic to the island of Crimea.
After the extinction of humans, predatory mammals experienced a period of temporary crisis caused by anthropogenic pressure. And at that time, representatives of other groups – rodents and insectivores – tried to occupy their niches. For example, during the Ice Age, predatory hedgehogs inhabited all of Europe. There was a population of spinywolves in Crimea, of the same species as on the mainland. However, after the retreat of the glacier and the emergence of Fourseas, Crimea turned into an island, and the mammals inhabiting it evolved in isolation. Some species failed to keep a viable population, and others, more adapted to limited resources in isolation, took their place. One of the ways of adaptation was dwarfism, and the descendants of the mainland spinywolf successfully followed in this direction, thus the dwarf spinywolf arose.
Body length of dwarf spinywolf is 50-55 cm, the height at the withers is 30-33 cm. It resembles its mainland relative in proportions, but its wool color is rusty-red with dark gray cross streaks; there are also completely black individuals and white ones with pale gray or reddish stripes. Dwarf spinywolf has quite numerous spikes, they run in several rows along the back and close at the rump – this feature has remained since the isolation of Crimea island. The dental system is adapted to predation; teeth are multicuspidate, adapted for piercing and cutting. Dwarf spinywolf hunts local small herbivores, occasionally eating reptiles, amphibians and carrion. It is only wary of an adult Crimean pygmy boar, although it does not miss the opportunity to steal a piglet of this species. It happens that feathered predators attack it or try to take away its prey, but dwarf spinywolf defends itself by snapping and turning sideways to the enemy with its spikes raised. Its cubs can become prey for the Tauridian adder.
The mating season takes place in autumn. The mating ritual is primitive: all courtship is reduced to chasing a female and fighting with a rival. Sometimes a female mates while several males are fighting each other. Pregnancy lasts until early spring – in winter, the development of the embryos stops. In winter, the animal does not run into hibernation, but becomes more sluggish and may not leave the shelter for several days. For delivery, the female makes a lair under the roots of a tree or in a thicket of bushes, or hides in a cave. There are 3-6 naked and blind cubs in the brood, which open eyes at the fifth day of life, and grow spikes being one week old. At the age of 3 months, they hunt with their mother, and at 5 they are completely independent. Dwarf spinywolves are sexually mature at one year of age, and their life expectancy is up to 10-12 years.

Oasis minute shrew (Suncus halophobus)
Order: Insectivores (Insectivora)
Family: Shrews (Soricidae)

Habitat: dry “oases” of the Mediterranean basin.
Oasis minute shrew is a descendant of Holocene Etruscan shrew (Suncus etruscus). This species is a relic of the times when the sea lapped in the Mediterranean basin, and the uplands were islands with conditions more favorable for life. With the retreat and drying of the sea, peculiar dry “oases” have formed on the islands, where drought-resistant trees and grasses grow on the soil not poisoned with salt, and peculiar natural communities of dwarf animal species are formed. Mammals are extremely poorly represented in these communities – they are exclusively rodents, insectivores and chiropterans. Oasis minute shrew is one of the local shrew species.
Like its relatives of human epoch, it is a tiny animal with an elongated slender body and a large head that tapers sharply into a long movable proboscis. The total length of the body ranges from 2 to 3.5 centimeters, not counting the tail, which can reach a length of up to 2.5 centimeters. The weight of the animal does not exceed 1.5 grams (on average 1-1.3 grams). Head is large in relation to the body, ears are large, and the hind limbs are equal in length to the forelimbs. The animal has 30 pointed piercing teeth, and its whiskers are short and dense. The upper part of the body and sides are covered with brownish-gray hair, the fur on the belly has a noticeably lighter color.
Typical habitats of this species are moist natural shelters (crevices, rock cracks) of the upper zones of mountain ranges, where dew settles in the morning, as well as thickets along the edges of small mountain reservoirs. This species prefers ready-made shelters, although in their absence it digs holes in a layer of leaf litter.
Representatives of the species are mostly nocturnal, feeding during the day only near their hiding place. Like most shrews, during the day oasis minute shrew needs to consume an amount of food that exceeds its own weight by 1.5-2 times or more. At the same time, the heart of oasis minute shrew beats at a frequency of 1,500 beats per minute. These animals are omnivorous, but they mainly eat insects, their larvae and earthworms, less often plant seeds. They can also hunt young toads of Mediterranean oases or newly hatched lizards. Oasis minute shrew lives for no more than 18 months.
Breeding season lasts from October to April, when the temperature is slightly lower than in summer, and there are more opportunities to find dew to drink. A small number of females are capable of breeding even in summer. Permanent pairs are not formed. Pregnancy lasts 12-14 days. The female delivers from 2 to 6 cubs, which are born naked and blind, and together weigh no more than a third of the weight of the female. They develop rapidly, and their eyes open on the 5th day of life. The female feeds them with milk for up to 15 days, and at the age of 4 weeks, the young animals become independent and capable of reproduction.

Sabre-toothed shrew (Smilosorex venator)
Order: Shrew-form (Soricomorpha)
Family: Shrews (Soricidae)

Habitat: forests of temperate and subtropical areas of Eastern Asia, Far East.

Picture by Alexander Smyslov

The mass extinction at the boundary of Holocene and Neocene freed multiple ecological niches. In early Neocene a peculiar experiment began in nature: the descendants of the surviving species started making attempts to develop new life forms. In deciduous forests of East Asia one representative of the relicts of early Neocenic insectivore radiation lives – the sabre-toothed shrew, a descendant of the common shrew (Sorex araneus).
This species has become somewhat larger than most shrews, known in the human epoch: the body length is 12-15 cm, the tail is 6.5-8 cm, and the skull size is 30.5-34 mm. At this species sexual dimorphism is expressed: the female is smaller than the male. Its ears are relatively small, the eyes are tiny. The muzzle ends in a mobile proboscis, swollen at the base and enclosing large olfactory chambers – the sense of smell at this species is very well developed and is the main sense used when searching for prey. The build is solid, stocky; the tail length is about half the length of the body. Hair on the tail is very sparse.
Like its ancestors, this is a carnivorous species. The specialization of its teeth is noteworthy: the incisors and canines have diminished and grow much closer to each other, and the first molars in the upper jaw have become larger than the others and stick out of the mouth. They erupt much later than the other teeth during the transition of the animal to adulthood. The base of the tooth is reinforced by bone, while the skull is shortened compared to other shrews and its front part is reduced. Molars, following the saber-like ones and growing opposite of them in the lower jaw, are enlarged and have a cutting edge with a thick layer of enamel. The jaws can open up very widely, and the bite force is large enough to be able to bite through the cervical vertebrae of a rabbit-sized animal.
Wool of animals of this species is brown, the belly and throat are colored lighter. The sabre-toothed shrew is a solitary territorial species; when meeting outside of the breeding season, these shrews growl, showing their teeth and trying to exaggerate their size, pacing in front of an opponent on outstretched legs and raising up hair on their backs.
This species feeds on relatively large prey: large invertebrates, mice, voles and rat cubs. In the hunt for rodents, the animals are helped by their long teeth; using them, the sabre-toothed shrew also can pierce the chitinous covers of beetles. Perhaps the sabre tooth developed mainly as a weapon for hunting for armored invertebrates. On occasion, this shrew attacks ground-dwelling birds, far exceeding its size, and often emerges victorious. Killed bird may be enough for it for feeding till some days, until the meat decays so much that it could not eat it. The sabre-toothed shrew also does not disdain carrion, and sometimes eats the remains of someone else’s prey. The relatively large size of this shrew reduced its appetite, but because of its intense metabolism it eats per day as much food as it weighs.
The breeding season lasts from May to September, the females manage to raise 2 litters of cubs. Males at this time are intolerant to each other and between them combats take place, in which the teeth are never used – the opponents fight and scratch each other with their paws. Pregnancy lasts for 3 weeks; the litter size is up to 5 cubs. Cubs remain in a shelter for 15 – 20 days, and then they keep near their mother for the same time. Brood follows the female in single chain, holding on by their teeth to the base of the tail of that which is ahead, the first one holding the tail of the mother. At the age of 50 days, females are already able to reproduce. Life expectancy is about 2.5 years.

Habitat: European freshwater reservoirs – rivers, lakes.
Mammals of Insectivora sensu stricto belong to the oldest placental mammals on Earth: they appeared at the very beginning of the Cenozoic and have changed little since then, remaining small animals that scurried under the feet of larger animals.
This situation has changed somewhat in Neocene. In the insectivores order, larger animals like spinywolf and related species living in Eurasia appeared, but most mammals of Insectivora order remained similar to their ancestral species – shrews, moles and hedgehogs. Lomie, a member of the Eurasian water shrew genus, is one of these species.
In its appearance, lomie resembles a typical shrew, but is large – about 12-16 cm long, not counting the tail. Wool is velvety, grayish-black of various shades (slightly lighter on the belly), very thick and water-repellent due to oily secretions that the animal carefully rubs into the wool. There are no webs on its paws, but the tail is deep, compressed from the sides, with a “ridge” of stiff bristles along its upper edge. It is the main propeller of this animal underwater; unlike many aquatic mammals of the human era, lomie moves its tail from side to side. Paws help to turn, cling to rocks and plants, or move along the bottom. Muzzle is long and elongated into proboscis narrowed in front; the nostrils are capable of closing. Lomie’s senses of smell and touch are well developed, its hearing is worse, and its eyesight is very poor, especially on land. Eyes are small; ears only slightly protrude from the fur, and they are equipped with a skin valve that closes the ear canal. Animal is able to dive to a depth of about 1 meter and hold its breath for 2-3 minutes.
Lomie is an exceptionally zoophagous species, feeding on various small animals – aquatic invertebrates (insects, mollusks and crayfish), less often small fish and amphibians. Like some other insectivores, lomie’s saliva is slightly venomous, and this venom helps it to immobilize its prey, as well as defend itself from large predators. Bite of this animal leads to partial paralysis, which passes after a few hours without consequences.
Lomie is a near-aquatic animal, not found far from water. This animal does not have a pronounced mating season; males and females are almost always ready to breed, but the peak of this activity lasts from early May to early September. Lomie does not form pairs; females raise their cubs alone. Pregnancy lasts for 2 weeks, with a brood of 4 to 8 cubs. They grow up fast, and at the age of one month they leave their mother. Females of this species usually give birth to 2-3 broods per year from some different males. By the age of six months, young animals are ready to reproduce. Lomie can live up to 5-6 years, but most animals of this species die in the first 1-2 years of life.

Monster shrew (Deinocrocidura philippinensis)
Order: Insectivores (Insectivora)
Family: Shrews (Soricidae)

Habitat: endemic to the Philippines, tropical forests.
During the Holocene-Neocene ecological crisis, the diversity of predators decreased. Taking advantage of this, mammals of some other orders tried to occupy the vacated ecological niches of carnivores. Among them were insectivores, which gave rise to a number of relatively large carnivorous species. Over time, most of these animals became extinct, unable to compete with the recovering descendants of carnivorans. But some species have survived, such as Eurasian spinywolves and catshrews from Asian tropical forests. Of the predatory descendants of Asian house shrew, only monster shrew persists by the Neocene, due to the isolation of Philippine archipelago from the mainland.
Compared to the insectivores of the human epoch, it is a giant, although in the Neocene fauna there are also larger descendants of shrews. Its body length is 58 cm, shoulder height 25 cm, weight – about 4 kg. Animal’s wool has a faint brown color, and the belly is of lighter color. It has a long narrow muzzle with a flexible proboscis, small pointed ears, five-toed clawed paws and an inflexible shortened tail that serves to store fat stock. Monster shrew feeds on rodents, amphibians and reptiles, as well as large arthropods and mollusks. Occasionally, it eats eggs, dead fish and carrion, and can kill a chick that has fallen out of the nest or a newborn Philippine trumpeter calf. It partly replaces the small felines that have disappeared here. This animal is solitary – it behaves aggressively to its congeners. Monster shrew leads a diurnal lifestyle. When an enemy attacks, animal utters a high-frequency squeak and grins its teeth, while simultaneously emitting fetid secretions from its scent glands. If the attack does not stop, the animal rounds on the enemy itself and inflicts deep lacerations with its teeth.
The breeding season is not pronounced, although the peak falls in autumn. During estrus, the female manages to mate with several males who do not participate in the care of the offspring. Although the males fiercely fight for the right to mate with the female, immediately after mating, the male leaves the female and does not protect her from the encroachments of other males. During the year, the female brings offspring 2-3 times.
Pregnancy lasts 7 weeks, and there are 4 naked, blind cubs in the litter. They are born in a hole, usually dug under the roots of a tree. At the age of 25 days, they are already fully developed and follow their mother in single file, holding the base of the tail of the cub in front with their teeth; the first of them holds onto the mother’s tail. At this time, they reach half the length of the mother. At the age of 4 months they are independent; 7 month old ones are ready to breed. Life expectancy is no more than 10 years.

Pishonia (Pishonia semicaeca)
Order: Insectivores (Insectivora)
Family: Aquatic shrews (Natarosoricidae)

Habitat: large rivers of Hindustan and Indochina.
In most river ecosystems of the human era, otters, several genera of mustelid family, took the place of large fish hunters. Human activity – hunting, overfishing, pollution of rivers and regulation of their flow – led to the sharp reducing of the number of these animals, and they became extinct at the end of the Holocene. In Neocene rivers and lakes, their niche is occupied by representatives of various orders of mammals, from monotremes and insectivores to carnivorans and rodents. For South and East Asia of the Neocene epoch, specialized fish-eating shrews are characteristic. The most typical species of this group is the relatively small fishing shrew (Aquasorex planicephala) native to China. However, among the related species there are much more bizarre creatures, that are adapted to the aquatic lifestyle much deeper. One of them is pishonia, which inhabits the large rivers of South Asia.
The name of this animal comes from the medieval European name of the Ganges River – Pishon. Pishonia is a fairly large animal: its body length reaches 100 cm, and its tail length is 60 cm. It has a long body and a laterally flattened tail, and its front and hind legs are equipped with well-developed webs. The whole body is covered with short hair of light grey color, along the backbone there is a stiff hairy “crest” of black color – it serves as a keel when swimming. When swimming slowly, pishonia sculls with lateral movements of its tail, but when moving fast, the hind legs serve as the main propeller, and the entire posterior part of the body (lumbar, sacral and caudal spine) is involved in the movement. During fast swimming, the hind legs move alternately, folding as they move forward and spreading the webbed toes wide during rowing.
Head of pishonia resembles the head of a dolphin: to capture prey, it has long jaws, stuck full of pointed teeth. Pishonia’s eyes, useless in muddy river water, are underdeveloped and very small. They are able to distinguish the contours of objects very vaguely at a distance of three to five meters, and do not distinguish colors. Ears are also almost invisible from the outside, but the hearing of this animal is much better developed than vision. Numerous vibrissae grow on the face of pishonia, providing excellent sense of touch. The nostrils are shifted towards the end of the muzzle. To navigate in space and search for prey, this animal uses echolocation (rudimentary abilities for it already existed in some shrews of the human era). In pishonia, the sound-reproducing mechanism is located in its nasal cavity, divided into several chambers by transverse septa. The septa represent pairs of elastic epithelial folds that work like vocal cords. With the help of the lungs, the animal drives air back and forth through the nasopharynx, and the folds work as vocal cords, reproducing a variety of sounds. Reception of the reflected sound signal is carried out via a massive lower jaw, like in whales.
By emitting a series of sound signals and analyzing their echo, pishonia gets a three-dimensional picture of the world beyond the limits of its vision. Echolocation is also used in communication between various individuals: between a female and cubs, as well as between individuals competing for food and territory. In addition, the animal actively uses odorous secretions to mark the boundaries of its territory.
In terms of ecology and lifestyle, pishonia is a cross between an Amazonian giant otter and a blind Ganges river dolphin. Its main food includes medium- and large-sized fish. Waterfowl and young aquatic reptiles and large amphibians also get on its table. Pishonia is active at dusk and at night, and spends daytime in a self-dug hole with an underwater entrance. This animal almost never comes ashore; only occasionally pishonias may be seen resting on the trunks of trees that have fallen into the water. These animals are territorial: each individual controls a part of the river and expels its congeners from there. Most often, border conflicts are limited to ultrasonic sparring, after which the weaker individual leaves the stronger one’s possessions, but sometimes it comes to a fight.
During the mating season, which takes place at the end of the rainy season, pishonias’ dislike of trespassers calms down. It is at this time that males mate with females. Mating rituals of these animals are not too complicated: the male simply chases the female and slightly bites her fur and paws. After mating, the male leaves the female. Pregnancy lasts up to six months, and delivery takes place in a hole. There are usually 2-3 cubs in a litter. First, the female feeds them with her milk, and then they pass to feeding on fish. Cubs usually stay with their mother for up to the age of 5 months, after which they begin an independent life. They begin to reproduce at the age of one and a half years.
The life expectancy of pishonia is 15-20 years.

Wormtonguer (Vermiglossorex formicivora)
Order: Shrew-form (Soricomorpha)
Family: Wormtonguers (Vermiglossotheriidae)
Habitat: Central and Southern Africa, savanna with small areas of wood vegetation, wood in foothills.

When an environment had stabilized after Holocene accident , the climate of Earth became considerably warmer and more humid. At animals the huge amount of new fodder resources had appeared, number and species variability of some animal groups had considerably increased. In warm Neocenic climate the area of various social insects had considerably extended, and they became a fodder resource for some species of animals representing new families, appeared in Neocene.
The wormtonguer is African variant of anteater being the descendant of any species of numerous African shrews (Soricidae). It is rather large representative of order: cat-sized, but it seems even more largly because of features of constitution. The head at animal is very long: it is the adaptation for feed in nests of social insects. The muzzle of shrews is usually extended to short flexible proboscis. This feature has received the further development at their descendant: the skull of animal is short and expanded in front, and increased nasal cartilages serve as support for very long mobile proboscis (making two thirds of length of head) with nostrils and mouth on the end. Nostrils have ring contracting muscles – it is the adaptation for protection against insect stings. Being feeding this mammal breathes by mouth in a step to tongue movements or holds the breath at all. Tongue is very long - it may be extended forward for length of proboscis of animal. The basis of tongue fastens to hypoglossal bone which has moved far back, to middle of chest. In mouth salivary glands producing sticky saliva thickening in air are well advanced. Teeth are original – incisors, canines and premolars are not present in both jaws, only sharp-edged molars have remained – two pairs in each jaw. With their help animal crushes caught insects frayed then by corneous outgrowths of stomach walls. But at young animals at which the proboscis is not advanced yet, among milk-teeth two cutters in each jaw develop nevertheless. Ears are short, they can fold across with the help of special muscle. It protects them from stings of insects.
The animal spends practically all life on the ground, but if it is necessary (for example, during flooding) it can dexterously climb on trees and even swim. Usually the wormtonguer moves on the ground on four legs. Hinder legs are plantigrade with straight claws and non-joined toes. On forepaws there are sharp claws, therefore animal at walking supports on lateral side of fingers (claws at walking are turned by edges to each other). Tail is strong, with thick basis where the fat accumulates, assisting to go through fodder shortage. On waist of animal there is special gland, secreting musk liquid. Colouring of wool of animal is not striking: head of males is dark-brown colored with white tip of proboscis, back is grey with brown cross strips, and tail is black. At females head is grey without white spots. Claws at animals of both sexes are sandy-yellow.
Wormtonguers are active in the afternoon: from dawn till midday and some hours before sunset. At this time insects are not so active and not so strongly bite, or hasten to nest and are not so aggressive. Having found the nest of termites or ants, animal rises on hinder legs, rests tail against the ground, and digs out the house of insects by strong movements of forepaws. It licks off running outside insects by tongue. Besides the animal can dig out of the ground larvae of beetles and gathers single insects from plants. Usually wormtonguers live single life, zealously protecting fodder site from encroachments of neighbours. Borders of this territory are diligently marked by sharply smelling musk liquid. In territory at animal there are some constant shelters, in one of which it spends the night and will spend hottest time of day. Only in breeding season borders of territories can be broken, and animals sometimes use this circumstance, redistributing fodder areas. Usually one female and some males take part in courtship ritual. Trying to impress the female, they walk on hinder legs, show claws and loudly snort. The female couples with strongest of applicant males though it frequently prefers most strongly smelling of them.
Two - three times per one year the female gives rise to three – four cubs. Newborn wormtonguers are naked, blind, with closed ears. At them there are very short proboscises, therefore they can suck milk without difficulties. The female hides them in specially dug hole and feeds with milk about three weeks. At three-week age young animals leave(abandon) a hole and gradually pass to an adult diet. About one week the female teaches them to find forage, than one week the young growth keeps near to it for protection. Later young animals pass to independent life, searching free territory for themselves. Young animals are not so specialized, as adults: their diet includes much more species of insects. When the proboscis starts to grow, the wormtonguer passes to eat extremely ants and termites. They become sexual mature at the second year of life; life expectancy is about 10 - 12 years.
Enemies of wormtonguers are predatory birds and mammals, sometimes large snakes and lizards attack them. The animal applies sharp claws to protect against enemies with which it inflicts to aggressor serious lacerations. Warning about intention to defend, animal emits odorous liquid and rubs itself’s back against stones or tree trunks. Also, sharply exhaling air through mouth, it utters loud sound – shrill whistle. Usually the predator has got from wormtonguer deep wound, remembers its shout of threat and pungent smell for a long time.

Snailer (Vermiglossorex malacovora)
Order: Shrew-form (Soricomorpha)
Family: Wormtonguers (Vermiglossotheriidae)

Habitat: Central and Southern Africa, flatland and mountain woods.

Picture by Alexander Smyslov

This mammal is similar to the previous species (and it is no wonder, they are close relatives!), but it lives mainly in damp places – in tropical woods and thickets of bushes on river banks. The reason is, that the food of snailer lives here - this animal eats basically snails of various species. For eating of such food at snailer the special adaptation was developed: on the end of its tongue horn thorns directed back have appeared. It permits to take spineless invertebrates from their refuges and shells. The muzzle of snailer in connection with difference in diet became much shorter than at wormtonguer, and teeth are advanced very poorly and submitted by one pair of molars (with very thin layer of enamel) in each jaw.
As against to extremely ground-dwelling wormtonguer, the snailer uses various biotopes for life. More often this animal meets among trees in damp tropical rainforest. It perfectly swarms up trees: fingers of snailer are thin and sensitive similarly to fingers of primates. But they are armed with sharp claws, permitting to cling, clamber and if necessary to break rotten wood. Tail of snailer is rather flexible and partly prehensile. Colouring of this mammal is very contrast, cryptic: the forward part of body (head, shoulders and chest) is colored black, back one is light grey, almost white. On forepaws of animal there are white “gloves” up to elbows and on waist and basis of tail – black round stains. The tail of animal partly imitates colouring of some wood snakes that protects animal from predators.
This species eats spineless invertebrates – larvae, worms and snails. Snailer is able to break rotten tree and to take by tongue from burrows larvae of capricorn beetles. Animal determines their presence, sniffing at apertures, bored by larvae in wood. The most usual catch of this animal includes ground snails making over half of its diet. Snailer takes them from shell, having cut edge of mollusc body by claw of the thumb near the edge. After that animal pins snail body on tongue, having pushed it in shell deeply to all coils, and by one jerk takes mollusc meat entirely, has left shell empty.
If it is a little number of ground snails in its habitat, animals from populations living near to rivers can dive into water, catching water snails. Having pulled out from water such catch, snailer carefully shakes off, and then deals with mollusc. Usually water snails, as against to ground ones, have protective corneous operculum on their shells. Snailer cuts its contractor by claw and then eats mollusc.
Snailers are solitary territorial animals. But as against to wormtonguers they eat more accessible and various forage therefore they do not have sharp intraspecific competition, and they are more tolerant concern to presence of neighbours.
As well as wormtonguer, snailer breeds some times per one year. Two times per year female gives rise to 5 – 6 cubs. Male finds female in its territory (usually it is the male from the fodder site located near), and some time both animals keep and fed together. Pairing repeats some times but when female will feel approach of pregnancy, it banishes male.
Cubs are born naked and blind, but grow quickly. At monthly age they actively study world around, observing for mother and founding food under her supervision. And at the age of three months they become completely independent. At the age of one and half years female is capable to bear posterity. Life expectancy of snailer is usually rather short – no more than 8 years. Obviously, it is connected with fact that adult animals are practically without exception infected with helminths, receiving them from forage – ground snails.

Desert jumping shrew (Saltasorex desertobius)
Order: Insectivores (Insectivora)
Family: Jumping shrews (Saltasoricidae)

Habitat: deserts and semi-deserts of North America.

Picture by Lambert

Bipedal jumping is a type of movement characteristic for some animals of open areas – this method of locomotion allows them to save energy and travel long distances. It has been chosen by numerous rodents (jerboas, kangaroo rats, some Australian mice), marsupials (kangaroos and kultarrs) and sengis. In Neocene, an endemic family of insectivores evolved in North America, which also move by jumping. Its representatives are jumping shrews, common in the deserts and plains of North America, Central Mexican Plateau and the deserts north of it.
Desert jumping shrew is a small member of this family: its body length is 10-12 cm. Externally, it looks more like a jerboa than a shrew: very long hind legs, shortened front legs and a tail with a tassel exceeding the length of the body by 1-2 cm (it serves as a balance beam when jumping) are well visible. Usually, jumping shrews move on their hind legs, but when walking slowly, they stand on all fours. The snout of jumping shrew is elongated into a slightly shortened and expanded movable proboscis, which acts as a filter to clean the air from dust and cool it. Ears and eyes are larger than those of ordinary-looking shrews. Animal’s brain is enlarged, especially the cerebellum, which is responsible for coordinating of the movements. Wool color of jumping shrew is not bright: body top is light brown, bottom is yellowish-white. Switch on the tail tip is two-colored, black and white – it performs a signaling function and helps to escape from a pursuing predator, distracting its attention. Fur on this switch falls out easily, and a predator grabbing the animal by the tail gets only a bunch of inedible hair.
Having changed its appearance, jumping shrew has not changed the gastronomic habits of its ancestors: this animal feeds on insects, and also often attacks small lizards and rodents, and the prey may not be inferior in size to the predator. The attack on the prey is remarkable in its cruelty and speed: the animal bites it and tries to pull out a piece of meat or inflict a deep wound with its sharp teeth. The saliva of this animal has slightly pronounced toxic properties, so after an attack, the prey becomes sluggish, and the tiny hunter chases it along a bloody trail. Jumping shrew goes hunting at dusk and at night when the heat subsides. Being a nocturnal animal, it spends the daytime in deep burrows; it usually does not dig them itself, but occupies rodent dwellings (often after eating the owners or their offspring).
There is no clearly defined breeding season in the life cycle of these insectivores; there are 2 litters of 4-6 cubs per year. Usually, the birth of cubs is timed to coincide with the beginning of spring or autumn rains. Pregnancy lasts 35-40 days. Cubs are born naked and blind, but they develop quickly and after 40 to 45 days they leave the female and lead an independent life.
The life expectancy of desert jumping shrews is short – it is up to 6 years in rare cases, but usually is much less.

Picture by Alexander Smyslov

A close relative of this species is coastal jumping shrew (Saltasorex littoralis), which has a limited range covering the Mediterranean climate zone along the Pacific coast of North America. In addition to catching insects and small vertebrates, these animals often search for food on the seashore, especially after a storm.

Striped jumping shrew (Velocisorex tigrinus)
Order: Insectivores (Insectivora)
Family: Jumping shrews (Saltasoricidae)

Habitat: grassy plains of North America.

Picture by Alexander Smyslov

The open areas of Neocene North America are characterized by an endemic family of jumping shrews. These insectivores of a very characteristic appearance form several species that clearly differ from each other in ecology and appearance. For example, desert jumping shrew (Saltasorex desertobius) lives in areas of arid climate. Grasslands of North America – the prairies – are inhabited by another species, striped jumping shrew.
Striped jumping shrew is the largest species of its family. Its body length reaches 25 cm, and its tail is up to 30 cm. Externally, it resembles a large jerboa or a very small kangaroo, and of the extinct mammals it is like representatives of Leptictidium genus. Striped jumping shrew has very long hind legs – this animal moves by jumping and only when moving slowly also uses shortened front paws, while the rump of the animal rises above the shoulders. Head of the animal ends with a movable proboscis, eyes are quite large, but the ears are relatively small. The coloration of striped jumping shrew serves for camouflage in tall grass: numerous dark brown vertical stripes run on the sandy background. Belly is slightly lighter than the back. At the tail tip a “flag” – a switch of elongated white hair – grows.
Striped jumping shrew feeds on large invertebrates, lizards, rodents and small birds. This animal consumes a lot of food, but is far from being as voracious as its ancestors – due to its larger size, its metabolism is not as intense. Long legs allow it to chase running prey for a long time.
Striped jumping shrew is active during daylight hours, but it is often awake at dusk, especially in the hot season. This animal sleeps in abandoned burrows of rodents and reptiles, and often settles in rodent colonies. The activity of striped jumping shrew does not change in various seasons of the year, since representatives of this species do not settle north beyond the line of freezing of reservoirs in winter. In winter, the activity of this animal decreases – striped jumping shrew spends more time sleeping. But in winter, when awake, this animal hunts for larger prey – birds the size of pigeons and larger.
Striped jumping shrews delivers offspring in the spring. The rate of reproduction in this species is relatively low: there is one litter per year and no more than 3 cubs. Mating games begin at the end of winter, being limited to the chasing of a female by a male. When two rival males meet, they behave aggressively and often inflict deep bites on each other, fighting for the right to mate. Pregnancy lasts for 6 weeks. A few weeks after birth, the cubs become independent, but they remain with their mother for some time. At this time, they leave the burrow and lead the same lifestyle as an adult animal. They become sexually mature in the second year of life, and kangaroo shrews live no more than 7 years.
This animal has many enemies: birds of prey, mammals and snakes. It often escapes from them by running, but sometimes hides in the grass, relying on camouflage coloring.

Ferocious condylutra (Condylutra ferox)
Order: Shrew-form (Soricomorpha)
Family: Moles (Talpidae)

Habitat: North America, temperate and subtropical latitudes, to the north up to Mishe-Nama Lake (southern and western coast); freshwater reservoirs of various kinds – from lakes up to swamps.

Picture by Alexander Smyslov

During the evolution process low-specialized forms receive advantage in survival first of all. Due to absence of specialization they show a wide spectrum of variability and can occupy various ecological niches. Highly specialized species, on the contrary, can develop only aside the amplification of specialization. This principle is shown evidently by insectivorous mammals of mole family. In Neocene their specialized representatives have kept characteristic shape of digging animal, and evolution of unspecialized forms had resulted in completely unexpected results.
In areas of temperate climate of North America one of unusual descendants of moles of Holocene epoch lives. The structure of muzzle gives out its origin: it is crowned up by long mobile proboscis which tip is surrounded with fleshy outgrowths. This animal is very large descendant of star-nosed mole (Condylura cristata) which leads semi-aquatic habit of life. The name of this animal, “Condylutra”, combines two names: “Condylura” – star-nosed mole (an ancestor of this species), and “Lutra” – otter (this animal partly replaces it in ecosystems).
Condylutra represents the ecological analogue of platypus and mink – it is aquatic carnivore eating large invertebrates and small vertebrates. This is an animal of streamline shape up to 60 cm long not including tail; individuals from southern populations are smaller.
Head of condylutra is flat and lengthened, with low brain cavity. Eyes of this mammal are very small, and sight is bad. But this animal searches for prey under water not with the help of sight. Its main sensitive organ is long snout extended to flexible mobile proboscis and covered with naked pink skin. On tip of muzzle of its ancestor mobile sensitive shoots grew, helping to search for food. In evolution process condylutra had further improvement of this sensitive organ. Overgrown shoots of condylutra’s snout have electrosensitivity. With the help of this feature animal can search in muddy water for small animals by their electric field. External auricles at this animal are reduced, and small ear apertures are closed by reduction of special ring muscle at diving.
Wool of condylutra is rich and velvety, colored grey. To give it the water-repellent properties animal regularly greases hair with oily liquid secreting by two large glands at the basis of tail. The animal finds a lot of time to look after wool, combing it by claws of hind legs.
Condylutra leads aquatic way of life and is able to swim quickly. Diving for prey, animal can stay under water till about 5 minutes. Short (about 10 cm long) tail of condylutra is similar to beaver’s tail a little. It is rounded from sides, and its back edge is dulled. Tail is covered with dense rigid skin and thin hair; it helps to speed-up at swimming and is usually used, if it is necessary for animal to swim quickly, not turning off (for example, escaping from predator or banishing the congener). In this case condylutra swims with the help of wavy movements of backbone in vertical plane. For underwater hunting animal uses other style of swimming. Forepaws of condylutra are transformed to narrow paddles with well advanced claws; animal uses them when it is necessary to swim slowly and maneuverably, surveying places in which prey may hide. Diving for food, this animal digs out bottom by claws of forepaws, overturns snags and climbs among stalks of water plants. Also with the help of forepaws condylutra digs at the riverbanks and lake coasts long holes with several exits. The main exit opens right under water, and some emergency exits in case of flooding of hole or occurrence of predator lead to shelters and to the ground surface.
Condylutra has kept predating habits of ancestor: it is exclusivaly carnivore. Teeth of condylutra are numerous (44 ones) and pointed. This animal eats any food of animal origin which may be found in water and near water: worms, molluscs, crayfishes and crabs, dead or weakened fish. Condylutra can ravage clutches and even attacks chicks of waterfowl, snatching them from under water.
It is solitary species with primitive behaviour, not forming pairs even in courtship season. Each individual marks the territory with musky secretions and protects it from relatives. Pairing at this species takes place in early spring, after clearing of reservoirs from ice. In southern part of area the repeated courtship season occurs in second half of summer. Male searches for the female ready to pairing guiding by smell, pairs with it quickly and after pairing the female banishes him (she is larger and stronger, rather than male). Once a year (at the south of an area 2 times per year) the female gives rise to 4 – 5 cubs in deep hole. The nesting chamber is always above water level. Newborn cubs are naked and blind. They develop within 2 months, leave the female and lead independent life. Young animals become sexually mature at the age of 6 – 7 months: in southern parts of area young animals from the second litter already participate in pairing and give rise to posterity the next year.
Life expectancy of condylutra does not exceed 5 years.

Long-spiked maurihystrix (Maurihystrix longispinosus)
Order: Afrosoricida (Afrosoricida)
Family: Tenrecs (Tenrecidae)

Habitat: Mauritius Island, highlands.

Picture by Alexander Smyslov

Representatives of ancient family of tenrecs in human epoch lived mainly at Madagascar and Comoro Islands (from this family only African water shrews lived in Africa). One of their representatives, rather large species, tailless tenrec (Tenrec ecaudatus), had been acclimatized by people at Mauritius Island. After extinction of mankind activity of introduced species had completely changed the nature of island, and evolution at Mauritius Island has gone in other direction.
The descendant of tailless tenrec is one of species of Neocene fauna of this island. At tenrecs there is very small brain, and this animal does not differ in complexity of behaviour. For this reason evolution of tenrec descendant has gone to the way of improvement of passive protection that was promoted by fine inclinations getting from the ancestor. The body of ancestral species was covered with wool with bristle-like spikes. This feature had received powerful development at the Neocene descendant, and this way the maurihystrix (literally means “Mauritian porcupine”) – the large tenrec with long spikes, similar to a porcupine, had evolved at this island.
The body length of maurihystrix reaches 60 cm at the weight of about 5 kgs. This is plantigrade sluggish animal with short limbs and rather large head. Paws of animal are tenacious, and on fingers strong claws grow, with which help animal gets various food. Head of maurihystrix is lengthened, with peaked forward teeth and nose turned to short mobile proboscis.
Wool of maurihystrix is short and bristly, grey-colored; on stomach it is lighter. On top of head of animal wool forms long hair “cop”. The top part of body (back, nape, top part of neck and shoulders) of this species is covered with spikes up to 5 cm long. Along the middle of back the crest of lengthened (up to 15 cm) spikes grows; with its help animal puts to predators dangerous wounds. Spikes of young animals are dark, at adults they gradually brighten.
This mammal lives in mountains and other dry places, thus avoiding a competition to Mauritian dwarf pigs, which are more moisture-loving. Maurihystrix is able to climb on trees. Adult individuals do it very clumsily, but young maurihystrixes climb quickly and dexterously.
This is solitary animal. Maurihystrix does not avoid relatives, but concerns to them indifferently, not establishing hierarchy. Only at appreciable lack of forage animals show aggression to relatives. Sight at maurihystrix is weak, and eyes are small. For it keen hearing and sense of smell are more important, because the animal often searches for food in high grass where visibility is very bad. This species is omnivorous. The significant part of its diet the vegetative food– roots and fruits of plants – occupies. Also it willingly eats insects and small reptiles, digs grubs and worms from ground. At an opportunity maurihystrix eats carrion.
The disturbed animal hisses and rears spikes, having turned sideways aside the enemy. The attacked animal actively shows an opportunity of self-defense, jumping up on four paws and having curved back like a cat.
Seasonal prevalence in breeding of maurihystrixes is not expressed. Pairing is not anticipated by the courtsip ritual, and the female raises posterity alone. Twice per one year it gives rise to many cubs – up to 15 ones in one litter. Newborn maurihystrixes are completely defenceless. They are blind, covered with thin wool without spikes. The female arranges for them a den in rich bush, or digs a hole under roots of tree. At week-aged cubs eyes are already opened, and wool becomes thicker. At three-week age they start to move in den actively and try to explore vicinities. Monthly cubs can already not lag behind the female. They abandon the nest and follow mother in wood. At this time at them spikes start to grow. The highest death rate at maurihystrixes takes place during the pass to independent life. The sexual maturity at young animals comes at the age of 18 months. Life expectancy of maurihystrixes reaches 10 years.

Flabellitherium, fan beast (Flabellitherium semisolaris)
Order: Afrosoricida (Afrosoricida)
Family: Tenrecs (Tenrecidae)

Habitat: Madagascar, savannas of the western part of the island.
In human era tenrecs were among the typical representatives of mammalian fauna of Madagascar. This group of mammals demonstrated a significant species diversity and differences in lifestyle. Among tenrecs arboreal, digging, aquatic and terrestrial forms existed. In human epoch there was a significant reduction in the number of these animals, and a number of species became extinct during the Ice Age at the boundary of Holocene and Neocene. But the survived species continued evolving, and among them new and unusual forms appeared, sometimes reaching large sizes. The species richness of small and medium-sized tenrecs also increased, and among them forms having unusual anatomical and behavioral characteristics appeared. One of these species is the whimsical flabellitherium, the “fan beast”, living in savannas in the west of the island.
The flabellitherium is a descendant of the tailless tenrec (Tenrec ecaudatus), a widespread and easily adapting species of this family. This species evolved to strengthen its passive protection, and eventually on the plains of Madagascar a tenrec similar to a porcupine appeared. The flabellitherium is a chunky and slowly moving beast; the adult weighs about 8 kilograms and resembles a small badger in constitution. If necessary, it can run fast for short distances, but cannot run for a long time. In fact, it prefers not to run away from enemies, but to use other methods of self-defense.
The back of flabellitherium is covered with durable movable spikes up to 20 cm long, which provide it the main protection from enemies. Spikes also grow on the animal’s head and neck, and also there is a stripe-like zone of their growth along the midline of the back up to the base of the very short tail. At the base of the spikes sparse and rigid elongated wool grows, visually enhancing the outline of the animal. Some spikes are thickened and hollow – they are used as rattles, further warning predators of intent of the beast to protect itself. The colouring of sides and belly of the flabellitherium is grayish-brown; on the back colors are more contrasting: a white background, on which black spots and strokes of various shapes are scattered. Spikes and wool between the spikes are grayish-white. This is warning coloring, reinforcing its threatening demonstration.
When frightened the flabellitherium raises upright its spikes that stick out in all directions and make the outline of the beast look like a fan. At the same time the flabellitherium turns its side to the predator, so the black-and-white color of his back is clearly visible to the aggressor. Until the predator keeps its distance, the flabellitherium loudly hisses and squeals, occasionally slightly trembling wit its body. At this point the spikes knock against each other, and a loud cracking sound is heard. If the predator attacks, the beast turns to it by spikes and tries to prick it. During the fight flabellitheriums bite strongly.
This animal has an elongated snout and a movable prominent proboscis-like nose. Its weak long jaws are equipped with pointed teeth. Resembling a porcupine outwardly, flabellitherium differs from it in diet: this is a zoophagous species, feeding on insects, small vertebrates and carrion. On occasion it willingly ravages bird nests.
Seasonality in reproduction at flabellitheriums is not expressed. This species does not form permanent pairs and each animal usually occupies a certain territory, banishing its relatives from it. Male finds a female ready to pair by smell and encroaching on her territory. It displays itself to the female, pacing in front of her on outstretched legs, slightly trembling and chattering its spikes. At the same time it opens its spike fan and bars the way of the female. If she tries to leave, the male rattles its spikes stronger and runs at her head, trying to stop her. If the female does not try to move out, the male gradually calms down and lowers its spikes, showing thus the absence of aggression. After mating the pair separates. The female can mate, still taking care for cubs of its previous litter.
Pregnancy lasts up to 60 days; during the year the female can make 2-3 litters of cubs, and then rests for about six months. The female gives birth to 1-10 cubs in a hole that she digs herself or occupies someone else’s. At birth, the cubs are hairless and blind, but within a few days after birth they are covered with hair, and at the age of 2 weeks their eyes open and spikes begin to grow. At the age of 6-7 weeks cubs can already leave the hole and walk through the territory with their mother, learning to search of food. Three-month young animals already leave their mother and live independently. At the age of 1 year, the animals reach sexual maturity. Life expectancy is 10 years.

Shield-faced mole tenrec (Malagasytalpa scutifera)
Order: Afrosoricida (Afrosoricida)
Family: Tenrecs (Tenrecidae)

Habitat: Madagascar, savannas and woodlands.
The fauna of Madagascar got very serious damage because of human activity. The large species lived at the island before human colonization had died out within several centuries. The species living in forests also had suffered. But even in human epoch island had been inhabited by groups of small endemic animals. Among them the tenrec family expressed remarkable variety. It included the species occupying various ecological niches and having shapes differing in great degree. This family has kept a variety in human epoch, and in Neocene it entered new heyday. Among Neocene tenrecs there are huge species, but all the same the majority of their species has the small size.
Insectivorous mammals of families typical for continental Africa do not live on Madagascar in Neocene, and tenrecs have occupied their ecological niches. In forests and bushes, in humus-rich soil many kinds of invertebrates live. And the top predator of underground habitats is the separate species of tenrecs looking like mole. This is a blind creature having powerful digging paws – shield-faced mole tenrec, the descendant of rice tenrecs (Oryzorictes spp.) inhabited this island in human epoch. It is specialized deeper to burrowing habit of life, rather than its ancestors. This animal is up to 20 cm long with long naked tail, short head and cylindrical body. The basic digging instruments are large forepaws; 3-rd and 4-th fingers carry huge claws on wide bases. 2-nd finger is short, and thumb can oppose against fingers. Nestling to digging claws it helps in keeping food and to bringing it to the mouth. Hinder legs have four toes, narrow foot and long claws. Tail is covered with corneous scales of grey color and thin hairs.
At this animal eyes had completely disappeared, and even the optic nerve had undergone a significant degeneration. Auricles visible outside are lack at this animal, and the acoustic duct is protected by small skin valve. Animal has massive bones; therefore it is not able to swim. But bones conduct the sounds extending through the ground, and this feature helps an animal to orientate in environmental conditions. Also whiskers growing on muzzle of animal serve for orientation. The muzzle of animal takes part in underground tunnel burrowing, and the top part of head of this tenrec is protected by strong hairless corneous plate of brownish-yellow color comparable in hardness with claws of animal; hence the name of animal and specific epithet “scutifera” meaning “shield-bearing”. Short velvety fur of black color with brownish shade permits this animal to move back and forth in tunnels equally easy.
Shield-faced mole tenrec is flesh-eater. It feeds on various invertebrates, attacks frogs, reptiles and the small rodents get into its tunnels. This species leads solitary way of life, and two individuals of this species behave aggressively having met each other. Among shield-faced mole tenrecs cannibalism is usual, and adult individuals frequently eat young growth, and even attack newborn cubs. Pairing is possible at any time of year. The female ready to meeting with male leaves odorous marks of pungent smell in tunnels. Pregnancy lasts till only 10 – 12 days. The female brings up to 10 naked helpless cubs quickly growing and becoming independent at the age of 2 months. In 5 months age young animals become adults. Feeding up posterity the female grows thin considerably, and after young animals left her, it restores the physical shape for a long time. For one year it brings up to three litters. Life expectancy of shield-faced mole tenrec does not exceed 4 years.

Stream elephant shrew (Desmanella natans)
Order: Elephant shrews (Macroscelidea)
Family: Elephant shrews (Macroscelididae)

Habitat: mountain areas of Zinj Land.

Picture by fanboyphilosopher

Split off from African continent, Eastern Africa, or Zinj Land, had carried away the highest mountain tops of the continent. In Neocene mountain tops of Zinj Land are still the kind of water wapour condenser, and the numerous streams merging in rough rivers full of rapids flowing down from them. In cold water water mosses grow, and their sprouts wave in current. Stones and plants are populated with numerous larvae of insects – May flies, caddis flies, midges and mosquitoes. Some of them scrape bacterial layer from stones and plants, others eat plants, and the third ones are predators and hunt not only invertebrates, but also fish fry. And insects, in turn, represent the food of original representative of elephant shrews adapted to aquatic lifestyle.
This species, stream elephant shrew, feels like very well in cold water and easily swims against fast current of streams. It descends from one species of elephant shrews of genus Elephantulus widely settled in Eastern Africa. Stream elephant shrew is a small species: it is like young brown rat the size. Fur of this animal is water-repellent, very dense and velvety. Colouring of fur is black: it helps this animal to be warmed quickly in sunny place, and it is very important at life in cold water of mountain streams. This mammal dived under water seems silvery because of air layer kept in wool. In order to support water-repellent properties of fur, stream elephant shrew takes a great care to it, combs it by claws and greases with oily secretions of glands developed in armpits. Forepaws of this animal are mobile and have sharp claws. Hind legs are much longer than forepaws, and the animal moves overland by jumps like jerboa. If necessary stream elephant shrew is capable to make jumps up to three meters long, and easily crosses the river by several jumps on stones, escaping from predators. This animal swims with the help of hind legs, having pressed forepaws against chest. Edges of feet are covered with long rigid bristles unbending during the swimming and increasing a rowing surface. Swimming animal makes pushes by two hind legs simultaneously. The tail of animal is long and thick – a stock of fat gathers in it being used in case of starvation.
Stream elephant shrew has very small auricles. The external ear of animal seems hidden in skin, and the top edge of auricle blocks an acoustic duct under water serving as a valve. The mobile proboscis helps this animal to search for food in water. Due to large eyes stream elephant shrew has good eyesight both on land and under water.
This exclusively species is an original kind of “desman” in mountain areas of Zinj Land. His diet includes insects and their larvae, snails, crustaceans and small fishes. Within the day one animal eats food in amount approximately equal to two thirds of its body weight. Stream elephant shrew leads exclusively solitaru habit of life, only the female and her posterity up to achievement of sexual maturity live together. This animal is strictly territorial, and marks the territory with the same secretions as it greases wool. For this purpose little mammal simply clamps a stalk of a grass between a body and a forepaw, and drags it through an armpit.
The courtship season at this species is not expressed clearly, and posterity is born at any time of year. Male searches for the females ready to pairing, guided by smell of their territorial marks. At this time it is extremely aggressive to contenders, and frequently kills their by bite in head. Three times per one year, after the pregnancy continuing about seven weeks, the female gives rise to posterity – 2 – 3 blind and helpless cubs covered with rich wool. The female hides a litter in shelter – usually in hole dug out under stones and covered with dry leaves. Within one month cubs grow and study to extract food, then the female stops to feed them with milk and only enables to spend the night in her shelter. The bi-monthly cub already leads independent life, and the four-monthly female is ready to pairing.
In especially cold time this species can run into short-term hibernation of which delay of physiological processes is typical and body temperature drops down to + 10 – 12°С. Due to this feature the organism of animal grows old not as quickly as at constantly active animals having similar physiology. Stream elephant shrew from high-mountainous areas are able to live 8 – 9 years, and individuals from warmer areas live no more than 4 years.

Ant elephant shrew (Myrmisengi saltator)
Order: Elephant shrews (Macroscelidea)
Family: Elephant shrews (Macroscelididae)

Habitat: Zinj Land, rainforests.

Picture by Alexander Smyslov

Elephant shrews represent a group of mammals very characteristic for Africa and kept primitive body plan. Split of Africa and separating of East-African subcontinent (Zinj Land) have resulted in isolation of the species survived in human epoch. And restoration of tropical forests has allowed some species to develop a new inhabitancy – forest underbrush.
The large species of elephant shrews lives in forests of Zinj Land – shaggy elephantine sengi (Rhynchoporcus monstrosus). It is one of largest species – its length is from above half meter. But in the neighbourhood of it the tiny mammal moving by jumps on two hinder legs lives – ant elephant shrew. This tiny mammal is about 10 cm long, and tail makes approximately the same length. It has wide mobile ears, large eyes and mobile sensitive proboscis. Hind legs of this little mammal are longer than front ones, on bottom side of toes corneous callouses develop, improving traction with a ground. Forepaws are mobile and have thin sensitive fingers.
The wool of this mammal is short and has reddish-brown color with black longitudinal strip from nape up to the basis of tail. Tail, paws and ears are hairless, covered with dark skin. Above eyes two bright yellow spots are located, helping to distinguish relatives in twilight of forest floor.
This species of animals leads an unusual way of life and searches for meeting of creatures carrying fear and panic to the majority of forest inhabitants. Ant elephant shrew searches for the columns of army ants creeping on the ground and keeps near them. The presence of ants frightens inhabitants of underbrush and forces them to search for a new refuge. And ant elephant shrew easily notices and catches them. One more source of forage is everything carried by columns of ants accompanied with it: the caught insects and larvae, and also ants’ pupae. Due to speed this little mammal can snatch out ants burdened with load from a column, and furious soldier ants simply have no time to do anything against it. Also this elephant shrew can hunt insects itself. It licks prey off by long tongue covered with sticky saliva.
These animals lead a solitary way of life, but have no precisely determined territory. If near to ant column two animal of this species meet, between them the fight flashes, accompanying with shrill squeak and bites of the opponent to shoulders and ears.
Pairing does not have the expressed seasonal character. Male finds the female by smell, pairs with her and immediately leaves her. After the pregnancy lasting about 6 weeks, well advanced cubs are born, capable to move independently. The female brings three litters (1 – 2 cubs each time) during one year. Posterity stays with her till first four weeks of life, and then starts hunting independently. Ant elephant shrew grows very quickly: the three-monthly female is already able to bring posterity. But life expectancy at this species does not exceed three years.

Clawed elephant shrew (Myrmiscelides macronyx)
Order: Elephant shrews (Macroscelidea)
Family: Elephant shrews (Macroscelididae)

Habitat: arid savannas of South Africa and Kalahari.
Elephant shrews represent a specific African group of mammals; in Neocene, their range includes Africa and Zinj Land microcontinent split off the African mainland. Many of the Holocene elephant shrews have become rare due to human economic activity. During the Ice Age, the tropical regions of the planet experienced significant aridization of the climate, which reduced the range of surviving populations of elephant shrews. And yet some of them survived and gave rise to new species. Neocene elephant shrews are very diverse in the Zinj Land. Their relative, clawed elephant shrew, a descendant of the round-eared elephant shrew (Macroscelides proboscideus), lives in South Africa. Its ancestor was helped to survive by its small size and the ability to live in arid savannas, and during the Ice Age, the round-eared elephant shrew even expanded its range.
Clawed elephant shrew has retained the relatively small size of its ancestor: the body length is about 25 cm, the tail is about 20 cm, and the weight is about 450-500 g. This is a kind of “semi-bipedal” creature: when the animal paces, it supports on all four legs, but when moving fast, it simply jumps on elongated hind legs, pressing the front legs to its chest. Tail serves as a balancer, as well as storage of fat reserves. Head is narrow, elongated, with well-developed movable proboscis. Ears are large, rounded, and permeated with blood vessels. In hot weather, they serve to radiate excess heat from the body. Wool color is camouflaging reddish-gray; belly color is slightly lighter.
Clawed elephant shrew feeds only on social insects – termites and ants; in this respect, it is more specialized than its ancestor. Claws on its front paws are quite large and strong: with their help, the animal digs into insect nests. Teeth are adapted for crunching the chitinous shells of insects – they are sharp and multi-cusped. Its incisors are reduced, canines are short, and the lower jaw is narrow. In this species, tongue is very long and can protrude far from the mouth. Salivary glands are well developed.
It is a solitary animal; each individual owns a territory of about one and a half square kilometers. During the day, the animal sleeps in a shelter (usually in a burrow), and at dusk it makes the round of its territory, digging into suitable termite mounds and ant nests. It often cracks them with its powerful claws; although the beast prefers to feed on termite mounds that have already been broken open by other animals.
The breeding season is from August to September. At this time, males leave their hunting grounds and search for females, marking trees and the ground with oily secretions produced by a special skin gland on the chest. This species does not form permanent pairs, and after mating, the male stays near the female for some time, driving competitors away. Pregnancy lasts 70 days and ends with the birth of 2 cubs. They are born well-developed and at the age of 60 days they completely switch to adult food, but they accompany their mother for a long time. At the age of 4 months, they are completely independent and leave their mother, starting an independent life and conquering their own territory. Maturity occurs at one year of age. Life expectancy is up to 8 years.

Atlas great sengi (Gravisaltator dolichops)
Order: Elephant Shrews (Macroscelida)
Family: Elephant Shrews (Macroscelididae)

Habitat: North Africa, Atlas Mountains and surrounding savannas.
In Holocene, strange-looking elephant shrews inhabited mainly Eastern and Southern Africa, with the exception of the small North African species Petrosaltator rozeti. But during the time of human domination, many of them became extinct, unable to withstand the destruction of their habitat. Some of the remaining species could not survive the aridization of the climate during the Ice Age. The survived species went through a stage of rapid speciation in Early Neocene, and new species appeared among them, including rather strange and specialized ones. Atlas great sengi, whose ancestor survived in the mountains, is one of them.
Compared to its ancestor, it is a real giant: the body length is 75 cm, the tail is 70 cm long, and the weight is up to 10 kg. Its hind legs are long and thin, with short blunt hoof-like claws and a pad of rough skin under the toes. Front paws are shorter than the hind legs, so Atlas great sengi most often moves by jumping like a kangaroo. It rarely moves on four legs, and usually does so on mountain slopes. The animal has a long head with a movable proboscis and wide ears that serve to remove excess heat from the body. Wool color is grayish-yellow, with an intermittent dark longitudinal stripe on each side. Teeth of the animal are pointed, with well-developed cutting edges.
Atlas great sengi is a solitary animal, it keeps in pairs for some time only during the mating season, and the females lead the offspring of the current year. It feeds mainly on insects (70% of which are beetles and orthopters), as well as small reptiles. It can also eat a small bird or mouse, which it deftly grabs when moving with quick jumps. This agile animal can catch small birds on the fly. The way it hunts is a bit like that of marsupial sharp-toother from Meganesia, but it does not hunt large prey. This animal spends the hottest time of the day in a self-dug hole, or in another shelter. Animal sleeps there for several hours at night.
Breeding season lasts from January to March. At this time, males fight for females, “boxing” and kicking each other with their developed hind legs. Pregnancy lasts for 100 days, and there are 2 cubs in the litter. Female keeps them in the burrow for the first time, returning to them for feeding several times in the morning and evening. Cubs lack characteristic dark stripes on their sides. At the age of 2 months, the female stops feeding her cubs with milk; at one year of age, the young sengi is already completely independent. Maturity comes in the 4th year of life, and life expectancy is about 25 years.

Tokoloshe (Dromeobestia tokoloshe)
Order: Elephant Shrews (Macroscelida)
Family: Elephant Shrews (Macroscelididae)

Habitat: humid savannas of South Africa.
In the human era, elephant shrews suffered more from habitat destruction than from hunting – they were mainly small animals that had no importance as an object of hunting. Later, during the Ice Age, the aridization of the climate led to the extinction of a number of their species. As a whole, the group survived, having quickly restored its biological diversity and habitat. In Neocene, most elephant shrews look like their ancestors, but there are also strange, divergent species. A large shaggy elephantine sengi lives in the forests of Zinj Land, and the humid savannahs of South Africa are inhabited by tokoloshe (a spirit from Zulu mythology), a descendant of four-toed elephant shrew (Petrodromus tetradactylus).
Tokoloshe is a relatively large species of elephant shrews: its body length is 65 cm, tail length is 52 cm. Wool color is sandy yellow with a reddish tinge on the back and rump; tail is covered with short hair, with a black hairy switch on the tip. Ears are wide and rounded. Proboscis is elongated and movable.
It is a ferocious predator that eats not only arthropods, worms and mollusks, but also small vertebrates. Tokoloshe simply grabs small invertebrates with its teeth and eats them, but it attacks snakes, rodents and lizards, killing them with blows of its hind legs. Attacking venomous snakes, it strikes its prey with a series of strong blows and bounces to the side or back, and then repeats its attack, pouncing on from the other side. This animal usually moves on all fours, and jumps when chasing prey or escaping from larger predators. Outside of the breeding season, tokoloshe is a solitary animal, expelling rivals from its territory. Only the female can be accompanied by the cubs of her last litter. The boundaries of the territory are marked with urine.
The breeding season takes place at the beginning of the rainy season. The mating relationships of these animals look more like a fight: in every possible way, the male forces the female to mate, displaying his dominance, and bites skin on her back. But these bites are rather ritualized – he only slightly clamps the female’s skin with his teeth, and the female does not pull out, which lets avoiding injury. But the ears of males are often torn and covered with scars: they scratch and bite each other’s ears. It is during the breeding season that the males’ voices can be heard – a deep barking through the proboscis. At this moment, the proboscis of the beast inflates. The dominant male drives competitors away from the female and marks the territory around her with urine. Mating is repeated several times for two to three days, after which the male leaves the female and does not take any part in raising offspring. Pregnancy lasts for 2 months, after which the female has one, rarely a pair of cubs. At 1.5 months they stop sucking milk, and at 5 months they are completely independent. Maturity comes at the age of 2 years, and life expectancy is up to 13 years.

Tree micropangola, “walking pinecone” (Micropangola scandens)
Order: Pangolins (Pholidota)
Family: Pangolins (Manidae)

Habitat: tropical rainforests of Hindustan, South East Asia, tree crones.

Picture by Alexander Smyslov

The order Pholidota was never especially numerous and diverse. At the beginning of their evolution these animals had adapted to feed on insects, having become ecological analogues of anteaters in Old World. This specialization caused their conservatism and imposed certain restrictions to the body size and way of life, having allowed animals to vary in quite strict limits. The upper limit of the body size of pangolins is rather rigidly limited, but the lower limit is limited by nothing, and one of Neocene species of pangolins – tree micropangola – shows it.
This species is adapted to life in tropical rainforest where it inhabits forest canopy – the place richest in life. To make it possible the animal had to offer in the sizes and physical power. Tree micropangola differs from its relatives in small size and truncated snout. The body length of this animal is about a half a meter, and wide muscled tail takes a half of this length. The body of micropangola is covered with corneous scales, as at its ancestor. But the scales are rather thick and strong, and the scales along the spine have pointed tips. On head and paws scales actually turn to corneous scutes located closely to each other. Primary color of scales is reddish-brown; sides of head are coloured lighter a little.
This animal has short snout, but the tongue is long and flexible. Its base is shifted far back and is attached to chest bone. Due to elasticity of tissues the tongue may extend from the mouth at the distance equal to double length of the head. Ears and eyes of this animal are small, and sight sense is bad. But it is compensated very much by keen senses of smell and touch which are used in food search. The feeding animal constantly taps on tree with claws and determines by the type of wood vibration the existence of cavities in wood mass – the tunnels and the chambers gnawed by insects. Having felt their presence, it breaks wood by claws and penetrates the tongue into the opened tunnels, licking off the insects.
Paws of tree micropangola are adapted for grabbing of branches. On forepaws strong and slightly bent claws nestle against the palm and form strong grap, allowing the animal to cling even on thin branches. Feet of hinder legs are covered with corneous combs allowing clinging to bark and branches much stronger. The tip of tail of this animal is expanded, and scales bordering the body edges are strong and peaked – it is an additional adaptation for fixation on trunk and branches. A usual pose of feeding animal is the perching a tail downwards. Thus scales at the back edge of tail stick to the bark and take up weight of the animal.
The main protective adaptation at this species is the set of strong corneous scales. They defend tree micropangola against birds and small arboreal predators. Defending itself, micropangola sits across the branch, envelopes it with tail like a ring, and covers the head with tail tip. Due to strong muscles the animal can keep such pose till about one hour. If the predator doesn’t stop attempts of attack or is too strong, tree micropangola can defend itself actively, imposing on it the near battle which can finish with serious injuries for the attacker. Thus, having grab the branch by hind legs and having clasped it by the tail, the animal sharply throws up a body, strikes to the enemy some fast blows by large claws of forepaws, and then clasps a branch again and hides the head under tail tip.
The seasonality in reproduction of this speciees isn’t expressed, but in areas of monsoonal climate the most number of youngs appears in rain season. The courtship ritual of tree micropangola is primitive and is reduced to chase of female by male. After pairing animals abandon each other. There is only one cub always; it stays with mother up to three-monthly age and then starts to lead independent life. Life expectancy doesn’t exceed 12 years.

The idea about existence of this species of mammals was suggested by Simon, the forum member.

Mole pangolin (Talpangola laticauda)
Order: Pangolins (Pholidota)
Family: Digging pangolins (Talpangolidae)

Habitat: Southern and South-Eastern Asia, woods and light forests.
Order of pangolins is rather conservative group of mammals. From early Cenozoic, according known fossils, they almost did not change structure and habit of life. But in epoch of mass extinction few successful forms which have standed “durability test” start to evolve actively, giving rise to new lifeforms.
Obviously on this wave one of pangolin species living in woods of South-Eastern Asia, had mastered new to this group habit of life, becoming practically completely underground animal.
Common length of the Asian mole pangolin is up to half meter including tail. Head of animal is wedge-shaped, flattened, covered with corneous plates forming continuous protective armour. With the help of such head animal can ram friable wood ground, digging a hole to it. Eyes are very small, protected from above by corneous “eyebrowes”. To protect eyes from ground at animal in addition there are advanced dense brushy eyelashes. Auricles are not present; ear apertures are covered by special corneous plates. Sight and hearing at mole pangolin are bad, but sense of smell with which help the animal searches for the forage (ground invertebrates, including social insects) is perfectly advanced. Nasal cavities occupy significant part of skull.
Forepaws with powerful claws are the basic “digging instrument” of mole pangolin. Claws on II and III fingers are especially advanced. Back legs are short, plantigrade, with large feet. Almost all loading during digging and movement falls on them.
At all species of pangolins known in human epoch tails were very long. Turning such tail around of body, pangolin could feel like in full safety from predators. At the mole pangolin the protective role of tail is lost, as the animal spends almost all life in holes, getting out from them only in case of emergency. Tail of the mole pangolin is wide and short, during short travel on surface of the ground it can protect an animal: the disturbed mole pangolin can turn having covered belly and partly head with tail. If the enemy will not recede, the animal makes sharp movements by forepaws, trying to wound the enemy by sharp claws.
Body is covered with scale armour, as at all representatives of order. Between scales it is only few wool, it is very thin. Edges of scales are covered with corneous hairs that strengthens coupling of scales and make their abutment more dense. Colouring of scales is rosy-brown. Because of continual friction against ground scales of animal are “polished” and gleam slightly. Horn hairs are formed at rubbing of corneous layer on edge of scale, and represent ends of fibres forming every separate scale.
During digging mole pangolin serially shovels ground by claws under belly and throws it back by legs. The main reason of special form of tail of this animal is its use during digging holes: from time to time the animal lowers shovel-like tail and starts to move back, raking by it away shoveled up ground to hole entrance.
This mammal eats insects and other invertebrates licking them off by long tongue. Basis of its diet are larvae of beetles rummaging in ground, earthworms and snails dug in the ground. Frequently this pangolin digs burrows to termitaries, visiting them by turns and breaking underground part of insect nests. When from the damaged nest hundreds of “soldiers” and working individuals run out for repair of it, animal simply licks them off by tongue, staying still.
Twice per year female gives rise to 1 – 2 cubs. As opposed to other pangolins, cubs keep on stomach of mother - if they’ll sat on back as at ground and climbing pangolins, female simply would dump them during movement. The female carrying cubs, digs ground more cautiously, preferring to move in ready holes.
Cubs leave mother’s stomach at fortnight age, but about one month they are fed with her milk. They become completely adult at the age of half-year. Life expectancy of this animal reaches 10 – 12 years.

Lupardus (Lupardus tenuis)
Order: Carnivores (Carnivora)

During anthropogenous pressure on nature number and variety of most part of large “noble” predators (felines, bears, canines etc.) had strongly decreased, and some species had completely disappeared. Populations of predators were so strongly undermined by human activity, that the most part of carnivores species had not gone through ecological crisis at the boundary of Holocene and Neocene, and had simply died out during several hundreds of thousand years when on Earth unproductive ecosystems had expressed. But completely new opportunities had been received by species which had successfully coexisted humans. In Northern America such species was coyote (Canis latrans) which had widely settled at the continent due to extermination of wolf and woods slash. This species had reached prosperity in Northern America, having evolved to some new species of predators.
One of descendants of coyote inhabits plains overgrown with grasses in the central part of the continent, stretched like wide strip along Rocky mountains from the north to the south. This animal is externally similar not to coyote, and not to the representative of canine family at all, and more to someone of felines. This similarity is reflected in the name of an animal: derivative of words Lupus (Latin “wolf”) and “-pardus” – the ending of names of some felines.
This species is specialized in catching of swift-footed medium-sized catch that had resulted in formation of running predator of the special appearance. A constitution of lupardus is rather light: animal has muscled sinewy body, thin long legs and flexible backbone. Claws at lupardus are short, but thick and sharp: they improve coupling with ground at run. By appearance it resembles other swift-footed predatory animals of Neocene: African pardinia and Middle-Asian zibetonyx (both animals are representatives of civet family). Losing to other predators in physical strength, lupardus surpasses them in speed: it is the fastest animal of the American continent, accelerating momentum up to 90 kms per hour at the short distance. During chasing of swift-footed catch it is practically out of competition.
At the lupardus there is small head with short muzzle. Jaws of the animal are rather short, but strong, with moderately long canines. Eyes are directed forward and provide good three-dimensional sight. The nasal cavity is short, but wide, and mucous membrane forms inside it numerous plicas. It considerably aggravates sense of smell of predator.
During intensive muscular work the animal is exposed to serious danger of overheat. The lupardus partly escapes from it due to fragile constitution, but it has also extra for cooling – very wide ears similar to ears of some desert foxes. When the lupardus chases catch, blood vessels penetrating ears, dilate, and excessive heat dissipates. Big auricles provide to the lupardus good hearing, that is especially important at hunting for small catch in high grass, where the visibility is bad.
Skin of the lupardus is colored light rusty with thin close black cross strips. This colouring resembles a little “tiger-like” colour of some breeds of domestic dogs. Legs of lupardus are dark; strips are not expressed on them. Internal side of wide ears is grey, but on external side of ear there is the big white spot edged with black wool. When lupardus is turned by muzzle directly to catch, its prey does not see the predator on the background of grass, but congeners standing behind perfectly notice white spots on its ears.
The basic catch of luparduses is deermara – the running rodent of South-American origin similar to small antelope. Except for them these predators hunt large flightless ostrich turkeys. Less often luparduses attack larger animals of American plains: donkeyhorses and young peccasons. At lack of large prey lupardus eats small animals: rodents, lizards and snakes. Usually it avoids to hunt among bushes or in high grass, preferring plains where grass is short because numerous herbivores eat and tramble it. Tracking down its catch, lupardus relies first of all on sharp sight; therefore for it the good field of view is important. Besides the high grass complicates run, and animal simply may fall, having hooked for stalks and having injured its legs. Having caught up prey, luparduses put to it strong bites in sides and hips, trying to pull out a piece of meat. With each such wound animal weakens more and more, and soon it falls, becoming catch of predators.
Swift-footed animals have one general feature: they get tired very quickly, and can not accelerate the maximal speed for a long time. Lupardus has the same feature, but it easily compensates such lack by other features of behaviour. As against cats and pardinias, and similarly to zibetonyx, it is packing hunter. Luparduses lead the chasing of catch by organized way, and in pack always there are animals, ready to join chasing. The pack of luparduses cuts the selected catch from the common herd, and drives it up to exhaustion. Thus hunting animals arrange ambushes, lining up. Herbivores cut from herd are “transferred” by hunters from one to another. In this case the prey is every time chased by all new animals, and by the end of chasing it is literally ready to fall down of tiredness.
Such hunting tactics can not be organized without close interaction between members of clan. Outside of hunting lupardus is the sociable family animal closely communicating with congeners. Similarly to other canids, lupardus uses for communication a tail with a white tip. By position of tail and ears animal expresses emotion and shows the mood. The clan is ruled by main pair in which the male is mainer than the female. Dominant male rules all males in clan and all females submit to the main female. Youngest animals are outside of the common hierarchy: the relation to cubs at luparduses is the most gentle and touching. Each female twice per one year brings posterity: up to three – four clumsy long-legged puppies. They differ from adult animals in black colouring, and it forces even dominants to suffer all their children's pranks.
The grown up animals also outside of hierarchy, but for other reason: they are driven off by adult animals, and young, but not developed to the full, animals lead hard life, eating scraps. Gradually they study to hunt. It occurs during the big hunting for large prey. In the beginning young animals are on supporting parts, and then most capable of them quickly rise on a scale of ranks up to the high position. And once any young strong lupardus will overthrow the leader, proving its own hunting abilities.

Nearctic hyena-toother (Neohyaenognathus macrodens)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: cold and temperate areas of North America, various landscapes – from plains up to deciduous and coniferous woods.

Canids are one of ancient groups of predators. They had made great progress at flat landscapes being habitat of numerous herbivores. In Neocene their destiny was changeable: having reached short-term success at plains of ice age, canids had conceded their positions to other groups of predators better adapted for woody districts and bushes. In such conditions canids had kept in very small amount. Besides number of many species had been undermined by people, and they had not gone through climatic cataclysms at the boundary of Holocene and Neocene. But some species managed to survive.
In North America descendants of coyote (Canis latrans) had achieved the great success in struggle for existence. Coyotes had got the big advantage from the neighbourhood with people, having expanded the area and having got rid from wolf, their main competitor. Possible, in first time after human disappearance hybridization of coyote and descendants of domestic dogs took place; it had resulted in enrichment of genetic information of new species becoming ancestors Neocenic of North-American canids. Besides preservation of canids in Neocene was promoted by geography of continent. Prairies formed in “wind shadow” of Rocky Mountains, had continued the existence in Neocene. They became the house for swift-footed herbivorous mammals and “range” for occurrence of new species of canids. Among them two lines separated, leading radically differing habit of life. One line of canids is represented by swift-footed packing predator lupardus, and another one is occupied with massive animal specializing to feeding by large catch – Nearctic hyena-toother.
Hyena-toother has occupied a convenient ecological niche of scavenger and large prey hunter. Other representatives of American predators - large cat balam and packing swift-footed canid lupardus catch small and swift-footed animals. But huge peccasons, giant pigs of American prairies, are too large and strong for them. But hyena-toothers are able to overcome such strong herbivore. This predator lives in small packs (up to 10 – 12 individuals) consisting of dominant pair and several subordinated pairs: they succeed to overcome large catch due to harmonious actions. However, they easily snatch catch away at other predators of prairies. This species effectively consumes large catch: after feast of pack of hyena-toothers only tears of skin, jaws and leg bones remain from catch. Other parts of prey are eaten completely.
Hyena-toother is a sizable predator (height at a shoulder is more than 1 meter) of massive constitution: the adult animal weighs up to 300 kg. It is similar to large and rather short-legged dog. Shoulders of animal are little bit higher than waist, and back of animal is sloping. Colouring of animals strongly varies: from light grey and even yellowish in southern and southwest areas up to grey with black back and almost completely black at the north.
Paws of hyena-toother are rather short, animal can not run fast and for a long time, accelerating maximal speed about 40 kms per hour. Toes of this animal are thick and short, and hyena-toother looks almost plantigrade. Not able to run fast, it swims well and easily walks on marshy ground due to wide feet. Often hyena-toothers preys swift-footed herbivores, pushing them to lakes and swamps and chasing them on fenny ground.
Jaws of hyena-toother are adapted to feeding in carrion and crushing bones of large animals: they are short and high, with powerful molars. Canines are big (especially at males: it is an attribute of a sexual dimorphism) and thick, with powerful bases. Tips of canines jut out from closed mouth of predator. But at some external similarity to sabertooth cats it is not their analogue by the habit of prey killing. If sabertooth cats operated by canines as by daggers, hyena-toother operates by them differently: it puts by canines shallow lacerations after which catch bleeds profusely.
Eyes of animal are small: sight of hyena-toother is rather weak; it badly distinguishes colors. But the hearing and sense of smell at it are excellently advanced. Also at hyena-toother there is high and wide nasal cavity, and olfactory epithelium forms longitudinal plicas. Ears of animal are big, rounded and mobile.
During search of catch hyena-toothers support contact with each other with the help of movements of tail with white hairy brush on the tip. When animals do not hunt, they actively use sounds for communication: hyena-toothers howl, declaring rights of clan to the territory, and also growl and whimper, expressing the mood. Puppies can bark, but adult animals lose this ability.
The social habit of life gives big advantages to the hyena-toother in hunting for large herbivores. Animals of different clans develop special tactics of hunting for large animals which transfers from generation to generation. Usually hyena-toothers choose the most perspective catch in herd of herbivores– usually it is young or rather old animal. They rush into herd, separate the planned victim from the common herd and drive it up to exhaustion. Hyena-toothers are not able to run quickly; therefore they drive prey, walking behind it. They have special places for killing catch where animals prefer to make decisive throw and to eat catch. Usually for these purposes places fare chosen, from which it is more convenient to reach lair and cubs.
At the period of hunting the young growth is looked after by old animals of clan. Usually young animals start to accompany with adults approximately from four-monthly age. Young males usually remain in parental clan at subordinated roles with strict hierarchy, and females either pass to other clans, or form their own one, which is leading by the male come from other clan.
Distribution of hyena-toother in North America to the south is limited by the border of temperate climatic zone. This animal is too massive; that’s why it badly tolerates heat. Therefore at Mexican plateau it is replaced by other American scavenger – marsupial hyaena (Phascohyaena tigrina), the specialized predatory descendant of the opossum.

Atshehaske, Great saber-toothed coyote (Smilodonocyon regius)

Coyote (Canis latrans) was one of the most successful predators of North America in late Holocene epoch. In Neocene coyote descendants had radiated to numerous species of predators of New and Old World. Among them Nearctic hyena-toother (Neohyaenognathus macrodens) is remarkable – it is huge canid having the certain features of saber teeth. Hyena-toothers did not become true saber-toothed predators, because during the evolution process they had adapted to carrion eating. But one canid descended from the same ancestors as hyena-toother turned to the real saber-toothed predator. It is atshehaske, huge saber-toothed coyot. The name “atshehaske” descends from Great Coyote – the Supreme deity of Havajo Indians. Like its “divine namesake” atshehaske differs in complex behaviour – this predator has remarkable cunning, insidiousness and nasty customs. The Latin name of species means “regal saber-toothed dog” and emphasizes appearance of this animal as well as possible.
Atshehaske is extraordinary beautiful and majestic animal. It is built lighter, rather than hyena-toother (the maximal weight of atshehaske does not exceed 150 kg.), and has more graceful proportions. The reddish skin of atshehaske is patterned with beautiful spots and strips of yellowish-grey, brownish and black colors. Males have beautiful yellowish-grey shabrack with reddish shade, and females lack of it. On paws there are cross strips breaking to separate spots on shoulders and hips. Tail is short enough, but fluffy, with black tip. Like hyena-toother, atshehaske has sloping back, but on the whole its constitution is much more graceful. Muzzle of atshehaske is rather short. The extended obverse part of a muzzle characteristic for coyotes evolved to rather massive forward part of the lower jaw. The upper jaw smoothly passes into powerful and strong forehead. Prominent feature of the upper jaw is the presence of huge canines – up to 25 cm long at males and up to 20 cm at females. Animal has large enough peaked ears on which tips there are beautiful brushes of yellowish-grey fur. In the whole, despite of low, flat and massive forehead, atshehaske is rather majestic animal.
On a way of hunting atshehaske is the real analogue of extinct large saber-toothed cats. It is an ambush hunter for large prey, unting in small groups. Attacking its prey atshehaske knocks it down and puts a bite. The predator uses canines as daggers – at the moment of bite in neck of prey canines of atshehaske simultaneously injure the large blood vessels carrying blood to brain and block respiratory ways. Prey dies from asphyxia and the termination of blood supply of brain. One more way of prey killing is putting large deep wounds in prey's belly, that causes fast death from bleeding. Atshehaske hunts most effectively in thickets of grass at riverbanks and shores of lakes where large mammals come to watering place.
Atshehaske is a social species, like the most part of canid species, and lives in clans united by consanguinity (usually patrilineal). Each clan jealously protects the hunting territory, marking its borders with urine. The courtship season begins in winter. At this time males gather near the lair of female ready to pairing, and arrange severe duels for the right of pairing. They do not use canines against contenders, but tear skin of each other by incisors, pulling out large pieces of wool and skin. But direct skirmish of competing males happens rather seldom. Usually duels are limited to demonstration of canines and an exchange of ritual poses. After pairing male stays with the female and in common they build a lair – wide hole under roots of tree. Animals also frequently occupy caves of natural origin. Male feeds up the female and stays with her until while his puppies will become independent. In litter it may be up to 3 – 4 puppies which will become independent hunters at the age of approximately one and half years. After posterity rearing the female has the year long break in breeding, and at this time male can couple to another female.
Life expectancy of atshehaske makes about 30 years.
This species of canids in Neocene is at the edge of extinction due to rather recent occurrence in their area of saber-toothed cat missopeho, the large predator. Populations of atshehaske are isolated also, and gene exchange between them proceeds slowly. Therefore small populations quickly degenerate because of inbreeding depressions. The most successful populations of this species live in Rocky Mountains and in mixed forests of the north. The large population lives in Appalachian Mountains, and along the northern border of prairies this species is present as small isolated populations. In significant area of northern forests this species was superseded by missopeho.

Common xolot (Anconocyon pratensis)
Order: Carnivors (Carnivora)
Family: Canids (Canidae)

Habitat: North America, meadows and prairies.

Coyote (Canis latrans) was one of the most successful predators of North America. In human epoch it had considerably expanded an area and had partly replaced wolf strongly exterminated at that time. Due to smaller size and variability of behaviour this species had freely adapted to life in anthropogenous landscape. After human disappearance coyote had kept the positions occupied in nature and had fixed its success, having penetrated along Beringian Isthmus to Old World. In North America coyote descendants evolved to animals looking unlike each other such as swift-footed gracile lupardus (Lupardus tenuis) and the hyena-toother (Neohyaenognathus macrodens), massive carrion devourer. But, undoubtedly, the most exotic and deviated descendant of coyote is xolot – the unusual underground coyote kind. The name “xolot” descends from the name of Xolotl – Aztec “coyote-headed” god of underground world.
There are some species of this animal living in North America. Common xolot is the most widespread among them. Common xolots inhabit meadows and prairies far from large rivers where there is no danger of flooding. They lead substantially underground habit of life and settle in small colonies in burrow systems dug out in prairies by large rodents. Xolots are omnivores with significant inclination to carnivory, and their food is diverse; they eat food of animal origin (ground birds, lizards, and also rodents – “builders” of their burrows) and vegetative food (roots and tubers of plants, young leaves and unripe seeds of graminoids). Though they rather frequently eat rodents in which holes they settle, xolots do not cause irreparable damage to colonies of rodents. Besides they rather jealously relate to their own territory, and do not let other predators to their home area. Therefore residing of xolots in holes of rodents is favourable for rodents to some extent. Though xolots attack them, they also simultaneously protect them from other predators. Damage caused by xolots to rodents is much less than possible damage other predators can cause to these rodents. Thus, between predatory xolots and their neighbours the certain biological balance is observed.
Common xolot is a medium-sized animal: its length including tail reaches 60-70 cm. The fur of this animal is short, rich and velvety, that interferes with its dirtying with ground and sand. Colouring of fur is light enough – usually it has bright sandy color, but there are individual deviations from grey and white up to red and yellow color. Paws of animal are strong, rather short and slightly bent. Xolot runs in its burrows and if necessary can easily dig out its own holes or expand already existing ones. The body of this animal is extended, and ears are rather big and wide, that is obviously atypical for burrowing animal. Anatomic feature of xolots as of separate genus is the presence in their ear of additional skinny membrane which simultaneously improves hearing and protects ear ducts from the ingress of sand and ground. Besides the auricle at underground movement turns back so that dust did not get into acoustic duct. Sight at xolots is rather weak, but the hearing and sense of smell are perfectly advanced. At night xolots go to the ground surface and feed on small animals and berries. They usually get roots and tubers during the tunnel digging.
Xolots live in small colonies numbering up to 10-15 individuals, consisting of breeding couple and their posterity. As a rule, males remain in group, and females leave it to settle in other place when reaching sexual maturity. They prefer to move to other colonies, using holes of rodents. These animals are afraid of bright sunlight, and if they appear on ground surface during the resettlement, they try to find any casual shelter.
The female brings posterity once a year. To give birth it arranges shelter in deep and well protected hole. Litter in shelter is made of rests of skins of prey or flocks of furs; the female adds to it a little portion of grass. For disinfection the female brings into the hole bunches of wormwood greenery and other odorous grasses, in order to get rid of parasites. In litter it may be up to 6-9 pups. They remain in shelter during first two months, gradually surveying holes in vicinities of their home. Young animals become sexually mature at the age of one and half years. Life expectancy is about 15-16 years.
In foothills of Rocky Mountains other two species of xolot live – nimble xolot (Anconocyon alacer) and mantled xolot (Anconocyon stragulumornatus), distinguished in smaller size and darker colouring. Males of mantled xolot have clearly expressed shabrack of reddish-grey color on back; females lack of it. As against to others xolots, sight at mantled xolot is better advanced, rather than at other representatives of genus.
At Pacific coast of North America false xolot (Subterracyon occidentalis) lives. It is also the coyote descendant, but it evolved independently of “true” xolots. False xolot is a bright example of convergent evolution. As against “true” xolots, false xolot has rather small ears, an additional membrane in ear is absent, and for protection against ingress of ground the auricle can fold lengthways with the help of special muscle. This species is a predator and builds holes independently, not using rodent colonies for the purposes. This species has strong forepaws on which the second and third fingers are armed with larger claws, than the others.

Minocyon (Minocyon pergracilis)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: cactus forests in the semi-deserts of Mexico.

Picture by Cossus

Coyote was one of the animal species that successfully survived the human era. During the period of restoration of ecosystems in Early Neocene, it has got an opportunity to evolve into a large number of descendants, some of which migrated to Eurasia, while others reached South America. A specialized desert-dwelling descendant of coyote, minocyon, has evolved in the Mexican deserts (the first part of its name means “coyote” in some Native American languages).
Body length of minocyon is about 100 cm, not counting the long tail. It has a very graceful constitution, slightly resembling cheetah of the human era and lupardus from the North American prairies. The legs are very long – the withers height of the animal is 65-70 cm. Tail length is about 30 cm. The animal is digitigrade, with rather large claws and corneous pads on finger and toe tips. Despite its graceful build, the beast does not run very fast: a lean build with a large relative skin surface is an adaptation against overheating in desert conditions.
Muzzle is thin and elongated, but it has a large nasal cavity and relatively wide nostrils. Ears are large, wide and pointed, abundantly permeated with capillaries – they serve to dissipate excess heat. Canines protrude slightly from the mouth. Wool color is sandy-red with a dark brown back, sometimes fawn individuals with an ochre back are found. Wool is quite short.
Minocyons live in cactus forests in the deserts of North America. They live in pairs, make their lair on the hillside, or dig under the roots of a cactus. The shelter is a relatively wide burrow up to 3 meters deep. These predators are active at almost any time of the day; they do not leave their burrows only during the hottest daytime hours. Minocyons hunt in the morning, evening and night. In a certain large cactus forest up to 5 pairs of minocyons can live. The animals are quite sociable and often howl together in the evenings. The hunting territories “radiate” from the settlement, which is surrounded by a neutral territory.
The prey of this predator is very diverse, but exclusively small: insects, arachnids, centipedes, reptiles, birds, small mammals. These desert predators often eat the fruits of cacti and other desert plants. Minocyons can also pull pueblo sparrows out of their nests. The enemies of these animals are large reptiles, gila-dragons in particular.
At the very beginning of the wet season, the female gives birth to 1 to 3 cubs. At first, the female feeds them with milk, and the male carries food to the female and protects the offspring together with her. At the age of one month, the cubs begin to leave the burrow, and at 3 months they learn to search for prey with their parents.
Sexual maturity comes at the age of 15-16 months, and life expectancy is up to 15 years.

Common uktena (Vafercyon uktena)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: South America, the outskirts of humid tropical forests.

Picture ny Lambert

Coyote (Canis latrans) of Holocene epoch was one of the most successful species of predatory mammals. In the New World, it became the ancestor of diverse species of carnivorous mammals occupying various ecological niches, from fleet-footed runners to heavy, slow-moving scavengers. The success story of coyote began back in the Holocene, when part of the coyote population reached Central America, evolving into Belize coyote (Canis latrans goldmani) subspecies, which flourished in the tropical forests of Guatemala. From there, the descendants of Belize coyote settled to South America, where, after the end of the human era, uktena genus (Vafercyon) arose. The ancestral species of this genus, descended from Belize coyote, was Vafercyon pseudospeothos, which occupied the ecological niche of the extinct bush dog (Speothos venaticus) at the end of Holocene. Vafercyon pseudospeothos itself disappeared in Early Neocene, but gave rise to a number of new species of Vafercyon genus. During the Neocene epoch, Vafercyon genus expanded its range and spread from the initial Early Neocene tropical forests in the north of the continent to the southern cold plains and forests, and to high-altitude valleys and plateaus. Animals of Vafercyon genus are usually small and squat. In appearance, uktenas are similar to the extinct bush dog. The most widespread species in Neocene South America is common uktena. This species inhabits an area that was covered by the Amazonian jungle in the Holocene, but prefers areas of disturbed forests and rarely enters a continuous tropical forest. Common uktena is a small short-legged animal; its body length, along with its tail, is 60-70 cm. Wool of common uktena is brown with a rusty tinge, throat and lower part of the muzzle are buff, and tip of the tail is dark red. Ears are pointed.
The main prey of common uktena consists of small mammals and birds (during the season of nesting on the ground). They live and hunt in packs of 15-20 individuals, preferring elevated areas of tropical forests where there is no danger of flooding during the river overflow. These animals live and breed in burrows that they dig under the roots of trees. The entrance to the burrow is usually located in a hard-to-reach place, and even the animals themselves can hardly squeeze into it. But the burrow is a comfortable dwelling with spacious tunnels, several living chambers and a toilet chamber, which from time to time is buried and settled in a new place. There are also one or two emergency exits. The settlement usually has up to ten inhabited burrows, as well as several abandoned ones, which can be used by young animals starting an independent life.
Twice a year, the female brings offspring – 5-7 puppies. Young animals begin to live independently at the age of 4 months. Life expectancy is about 10-12 years.
To the west of the range of common uktena, a smaller forest uktena (Vafercyon silvaticus) lives, inhabiting forests in the foothills of the Andes. In its lifestyle, it is similar to common uktena, but it is less social, and forms groups of 5-6, occasionally up to 8 individuals. The body length (with tail) is about 40-50 cm. Wool is black or dark brown. Life expectancy is approximately 10-11 years.
The banks of Amazon river and its tributaries are inhabited by crab-eating uktena (Vafercyon cancriphagus), which differs from the other representatives of the genus in its ability to swim and dive well. Crab-eating uktena feeds mainly on invertebrates – crustaceans, large snails and insect larvae. It also willingly eats fish that appeared captured in shallow water pools after the water subsides. Body length along with the tail is about 60 cm; fur is reddish-brown. Ears are able to close due to a special skin valve. Unlike most species, it lives in family groups. The life expectancy of this species is 12-14 years.
Pampas uktena (Vafercyon pampaphilus) inhabits the grasslands of South America. Pampas uktena is a pack hunter of open spaces. This species lives in numerous packs, numbering up to 40-50 individuals, sometimes up to 70 individuals. The animal itself is not large (body length with a tail of about 70 cm), but when acting in a pack it successfully hunts prey much larger than a single animal can get. Despite its rather short legs, it can reach speeds of up to 40-45 km/ h, and hunting in a pack allows it to surround prey – deermaras or young animals of other large rodents, up to barocavia cubs. Wool of pampas uktena is striated, with intermittent dark strokes on a light red background. This pattern allows it to disguise itself well in the grass. Pampas uktenas live for about 10-12 years.
The Andean highlands are inhabited by several geographically isolated species related to each other:
Mountain uktena (Vafercyon montanus) inhabits the northern part of the Andes mountain range, preferring areas overgrown with low-growing mountain forests and thickets of large perennial grasses. Wool color is yellowish-gray with a dark “cross” on the back and shoulders; belly is white. This animal is similar in size and proportions to a fox, but it has a shorter tail and a strong build. The main prey items of this species are large caviomorph rodents, which it hunts in groups of 6-8 individuals. It also eats reptiles and small birds. This species is diurnal.
Kingly uktena (Vafercyon regius) is the largest in the mountain species complex, with a body length of up to 80 cm. It inhabits the Altiplano plateau, leads a diurnal lifestyle and hunts large herbivorous mammals – local species of deer and caviomorph rodents. Fur color is silver-gray, but there is a beautiful dark gray shabrak on the back. This species is the least social in genus, living in groups of 2-3 breeding pairs and their offspring. Animals dig burrows according to the number of breeding pairs with several separate living chambers. The group aggressively defends its territory from outsiders.
Singing uktena (Vafercyon cantor) is the smallest among mountain species: its body length is about 30 cm. This species resembles a small fox with a short tail and small rounded ears. Wool is very thick, ash-gray with a bluish tinge. The main food of this species is small rodents and marsupials. It willingly settles in the burrows of large local rodents and gets along with them relatively peacefully. Colonies occupy a large territory: several tens of meters can separate burrows. But an important unifying force for the colony is the joint “singing” in the morning and evening, when the animals emit loud howls and barks for about half an hour with short breaks. This species is found in the southern part of the Andes mountain range and on the Altiplano plateau, where it often warns burrow owners in a loud voice about the appearance of its large relatives.
Silver uktena (Vafercyon argenteus) is a secretive species inhabiting the eastern slopes of the Andes in a subtropical climate zone. It is a small nocturnal animal that feeds on small rodents and birds. Wool of this species is light gray, and occasionally there are white individuals which, however, are not albinos. Colonies of this species number up to 10 individuals and occupy 3-4 burrows located close to each other in bushes or among rocks.
The Pacific coast of South America is inhabited by coastal uktena (Vafercyon littoralis), which has a lifestyle similar to crab-eating uktena. This species is isolated from other lowland species by the Andes mountain range and has been developing independently for a long time. It has short, strong legs, large head and strong jaws. This species feeds on mollusks, crustaceans and seabird chicks.
Vafercyon genus entered North America via the Antillean land bridge: in Florida and in the vicinity of the Appalachians, North American uktena (Vafercyon transmarinus) lives in open areas, leading a lifestyle similar to Pampas uktena, but less social. Packs of North American uktena reach 20-30, rarely up to 40 individuals. Wool of this species is dark, chestnut-colored or almost black, with a lighter spot on the throat; reddish and fawn individuals are occasionally found. The main food of this animal consists of reptiles, birds and small mammals – hares and rodents. 2 times a year, the female brings offspring – 4-6 puppies. Several adult individuals (usually old, unable to run fast) stay constantly in the colony, taking care of the young.

In Early Neocene, the Caribbean islands had connected to each other by land bridges that existed for more or less a long time; it allowed some representatives of South and North American fauna and flora to migrate to neighboring continents. Among the carnivores, the migrants were representatives of the South American uktena (Vafercyon) genus. The result of their settlement to the north is the presence of representatives of this genus on some Caribbean islands: they are typical components of the island fauna.
The mountainous regions of Great Antigua island are inhabited by one descendant of South American immigrants, Caribbean uktena. It is a dwarf species that prefers arid habitats and is not found in the tropical forests of the island, where the main terrestrial predator is a giant terraguana lizard (Terraguana monstrosa). Therefore, it is possible to say that Caribbean uktena is in double isolation: its population is located on an island and is surrounded not only by the ocean, but also by tropical rainforest.
Caribbean uktena is built like a very small fox with a large head, large ears and a short tail. The shoulders height of an adult individual does not exceed 15 cm. Wool color of this species is one of the brightest among uktenas: the background color is grayish-yellow, and a black stripe stretches from the back of the head to the tail base. Animal’s paws also have black “socks”, and there is a white spot on the throat. This animal prefers to live in the forest or among bushes, where this coloration serves as a good disguise and helps to track down its prey.
Animals of this species live in groups of 10-12 individuals, occupying up to 5 burrows dug in close proximity to each other, usually under the roots of trees. There is a dominant pair in the group, which usually has more cubs in the litter – up to 5 ones, while subordinate individuals have 1-2 ones. Offspring are born up to 3 times a year.
Caribbean uktena feeds mainly on small rodents, reptiles, land-dwelling crabs and insects, and occasionally attacks birds. These animals often enter caves, where they feed on insects and baby bats fallen from the cave roof.
Young males usually stay in the parent group, while females easily move from one group to another or join groups of “vagrants” and live on the borders of the territories of settled groups without permanent shelter. Such “tramps” often join an existing group, but sometimes, on the contrary, other males join them and such a group reclaims a permanent territory from its relatives and establishes its own settlement. Like other small mammals, sexual maturity in the Caribbean uktena occurs at the age of 3 months, and life expectancy does not exceed 4 years.
Island species of uktenas persist only on the large islands of the former Antillean Bridge. On small islands, the remnants of their populations gradually died out, having appeared in isolation in conditions of limited resources. Cuba harbors Cuban uktena (Vafercyon cubensis), which inhabits forests of various kinds. This species is slightly larger: adult males reach a height of up to 20 cm at the shoulders. These animals have an expressed sexual dimorphism: males are larger and heavier than females. This species has dark red fur and white spots on the cheeks and above the eyes; the outer surface of the ears and the back of the head are black. Cuban uktena lives in packs of one dominant male and several females and subdominant males. Most of the young in the pack are the offspring of the dominant male. Prey items of this animal are large rodents and reptiles, as well as birds.

Ant wolf (Microcyon insectophagus)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: South America, the outskirts of tropical rainforests.

Picture by Cossus

Adjacent to uktena (Vafercyon) genus is the atypical genus Microcyon, represented by a single species named as ant wolf. Like the African grumbling ant-mungo (Myrmungopsis myrmivorus), this carnivoran species displays a deep specialization in insect feeding. It is a very small animal – the body length, together with the tail, is only 15-20 cm. In its physique, microcyon resembles some domestic dogs of very small breeds that existed in the human era. It has a gracile physique, thin legs and a short tail.
Molars of this animal are pointed and multi-cusped, like those of insectivorous mammals; the incisors and canines are shorter than the other teeth. Tongue is highly elongated and elastic, and can protrude far from the mouth. It is covered with viscous saliva, to which insects easily adhere. Wool of ant wolf is tough and relatively thick, although the animal lives in a tropical climate zone – it is a protection from accidental ant stings. Wide auricles give the animal’s muzzle a bat-like appearance. They serve for heat dissipation, and their mobility helps microcyon to detect the direction of sound. Thanks to its keen hearing, this animal can find insects even in dense grass or at dusk. There is a special protective valve inside the ear that can close and protect it from insect intrusion. Nostrils can also close when the animal is feeding. Large eyes are protected from insects by stiff eyelashes.
Wool of ant wolf is dark brown, turning ochre-red on the throat and belly; legs and tail are dark. There are white tufts on the tips of the ears that perform a signaling function. The graceful physique gives this animal a fast runner and jumper. The startled microcyon jumps into the air with a squeal, signaling its relatives, and then tries to escape by making sharp turns and sometimes even jumping over the chaser. Animals that are not busy caring for their offspring often accompany myrmedillo (Myrmedillo destructor) – large insectivorous armadillo – and feed on insects when this animal crack the tough shell of a termite mound with its claws.
Ant wolf’s diet includes a variety of insects and spiders. These mammals often attack columns of army ants and manage to eat a lot of insects before dangerous soldier ants attack them. The diet also includes large beetles, which ant wolf simply turns over on its back and eats their soft abdomens.
Microcyons are social animals, living in groups of 2-3 families, usually occupying rodent burrows. The group members mark the boundaries of the territory with their urine. In case of danger, they emit a loud warning bark and try to hide in a bush or in a hole. If there is no way to retreat, microcyon bites and even hangs on the aggressor’s body with a death grip. Another interesting defense mechanism is the ability to shoot at the enemy with its liquid feces. This is how microcyons protect themselves from small terrestrial predators.
Ant wolf belongs to the number of small mammals, so its individual development occurs very fast: at the age of 4 months, a young female is already ready to bear offspring. There are usually up to 8 very small, naked and blind puppies in a litter. The female takes care of them until the age of 2 months, when they become completely independent. Soon after, she mates again and bears a new litter. During the year, the female brings offspring 2-3 times. The life expectancy of this animal usually does not exceed 3 years.

Kurī hou (Notokami pseudolupus)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: New Zealand, North and South Islands, most vegetated habitats, including mountain slopes, grassland, forest and marshes.

Picture by Cossus

The domestic dog (Canis lupus domesticus) has been a constant companion and loyal friend of man, used for companionship, food, war and hard work. Ancient Maoris brought dingo-like domestic dogs with them to New Zealand, the Kurī, which later became extinct in modern times. White man’s coming to New Zealand brought farm dogs, pet dogs, and large dogs used for hunting pigs. As the Holocene ended and man left these animals to run wild, they became a more homogenous, dingo-like mongrel again, and eventually evolved smaller size due to their island habitat.
The result is the Kurī hou (Maori for “new dog”), a creature partway resembling a dingo, and also a small wolf. Height at the shoulder is only 60 centimetres, its legs are shorter proportionately than a wolf or dingo, head is shorter and its tail is bushy and curls upward a little, traits derived from its domestic ancestry, weight is up to 31 kilograms. Colour is a general tawny brown, with a dark brown back, the end of the tail and face are darker, belly and underside are whitish. Populations found on the North Island are darker, and melanism is relatively common there.
This dog lives in packs, similarly to a wolf or dingo, that consist of a mated pair and their grown offspring, as many as 8 individuals, the older animals (including parents) are usually the dominant. Lone individuals consist of grown young which have been pushed out of the pack to start one of their own, but offspring may stay with the family pack for as long as 3 years. As with wolves, they establish a large hunting territory to maintain a good supply of food, prey hunted as a pack may consist of large birds such as pheasant or geese, rabbits, and various fair sized ungulates including certain kinds of deer and sheep. Smaller prey such as rodents, lizards and insects are also taken, as well as carrion and fallen fruit such as blackberries. These dogs proclaim their territory by howling communally, but as with the dingo, they are unable to bark, scent marking is also used. Other vocalizations include yips, yelps, whines and growls.
Kurī hou are monogamous, and a single mated pair will remain together for life, sexual maturity is reached at 2 years. Oestrus and rut begins in spring, such as September or October, and lasts for 3 weeks. The female constructs a large comfortable den, which is usually dug in lee of a tree root or large rock for protection, and a convenient distance from water-sources. Gestation is up to 70 days, and litters consist of up to four young, which are nursed in the den, leaving it first after 3 weeks and being very mobile at 6 weeks. Pups start to eat solid food regurgitated by the mother after four weeks, and during initial denning time, father returns to regurgitate food for the mother. Pups begin being able to hunt with their parents after 3 months. Lifespan is up to 7 years but usually shorter.

New Zealand False Fox (Vulpecanis aotearoae)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: North and South Islands of New Zealand, forest, woods, scrub, bushland, foothills.

Picture by Cossus

Unlike in Australia, foxes were never established as an invasive animal in New Zealand, but the descendants of the run-wild domestic dogs have prevailed there in the Neocene, producing convergent fox-like forms.
The New Zealand False Fox is descended from the domestic dog of the Holocene human occupation, but has adapted towards a more fox like shape and size. This animal has an elongate body and relatively short limbs, like a fox, and a mid-length bushy tail. Fur colour is a light reddish brown, with the back being slightly darker, underbelly and cheeks are whitish, and extremities of limbs and tail are dark brown. False Foxes reach 35 centimetres tall at the shoulder, with a body length of up to 48 centimetres, and a 28 cm long tail, weight is up to 7 kilograms. Fur is denser, fluffier and darker in colour, in the southern part of its range where climate is colder. The snout is somewhat more elongate proportionately than its ancestor and the face is fairly broad, the molars are a little broader to accommodate an omnivorous diet, ears are large and pointed.
Diet is that of an omnivore, including birds, fish, lizards and rodents, insects, fallen fruit and nuts, roots, mushrooms and carrion.
Territories are shared by family groups, and males will mark their territorial boundaries with urine. Within any one family there may be subordinate individuals sharing the territory. Individuals dig dens to shelter in, or use the abandoned holes of other animals, dens are also used for raising cubs. Calls vary from a loud earnest barking call to communicate over long distances, to whining and snickering noises when communicating among themselves at close range. Unlike its ancestor, they are able to sometimes climb trees to escape predators.
Mating occurs in the spring, females have their oestrus in September or October. Males will mate with the female several times during the 3 week receptive period, mating is generally monogamous but litters with multiple sires do occur. Litters consist of between 4 and 7 cubs, which are born with their eyes closed and are an overall dark brown. Mothers stay in the den with the kits for up to 2 weeks until they open their eyes and start to move about, nursing lasts up to 7 weeks. Young resemble their parents after about 7 months, reaching sexual maturity at about 10 months to a year old. Life expectancy is up to 5 years.

Tsitsu, the wild hound (Neocanis tsitsu)
Order: Carnivors (Carnivora)
Family: Canids (Canidae)

Habitat: steppe areas of Europe.

Picture by Wovoka

Initial picture by Lambert

Descendants of coyote (Canis latrans) have given rise to numerous Neocene predators of both Americas. But right at the beginning of Neocene congelation coyotes had penetrated into Eurasia through Beringia. At the end of Holocene only Bering Strait prevented coyotes to begin a gain of Eurasia, and at early stages of congelation when the ocean level had gone down, but Beringia had not completely disappeared yet under glacier shield, coyotes realized the opportunity opened to them and had intruded Old World from the east. As against their American relatives, the destiny of Euroasian coyote descendants was changeable. Having reached short-term success during Neocene congelation when they had widespreaded practically across the whole Eurasia, after climate change they were in the majority superseded by descendants of local predators and partly newcomers from the south. But coyote descendants had confidently reserved for themselves one climatic zone of Eurasia – steppes of Southern Europe and Three-Rivers-Land where wild hound tsitsu lives, a swift-footed canid species of gracile constitution.
In steppes of Eurasia tsitsu occupies the ecological niche similar to occupied by African hunting dogs (Lycaon pictus) in African savannas at the end of Holocene. If to be exact, tsitsu is the coyote descendant not in full degree: they descend not only from it. Hybridization as a way of speciation is rare phenomenon in nature, but it also takes place. The majority of Holocene representatives of Canis genus (except for black-backed and side-striped jackals) had identical number of chromosomes and was able to interbreeding (interspecific hybridization). Tsitsu has polyphyletic origin. The basis of tsitsu ancestral line is made of Alaskan coyote (Canis latrans incolatus) descendants, but among tsitsu ancestors there were also feral descendants of domestic dog (C. familiaris), and also descendants of Asian jackal (C. aureus).
Tsitsu is highly social pack hunters. The average number of individuals in one tsitsu pack changes from 70 up to 90 individuals (not including pups), the record number of individuals in pack can make 146 adult individuals. Each pack controls an area of approximately from one and half to two thousand square kilometers. There are two subspecies of tsitsu, one (N. t. europaeus) of which lives in Southern Europe, and another (N. t. rufus) inhabits Three-Rivers-Land. Subspecies differ in colouration. N. t. rufus has “standard coyote” monophonic reddish color while yellowish-red skin of N. t. europaeus is speckled with spots and small strips of white and grey colors which help this animal to be imperceptible in grass. In winter the wool turns denser and lighter a little. Tail is reddish with black tip; its position is used by these canids for communication and expression of emotional condition. Ears are big and pointed; paws are narrow. Canines are rather long, much longer than at Holocene coyote.

Picture by Wovoka

Tsitsu is medium-sized animal. In dimensions it approximately corresponds to polar subspecies of Holocene coyote. Weight of males makes about 20 kg, females are about 16 – 17 kg. Despite of the dimensions, packs of swift-footed (developing speed up to 75 - 80 kms per hour in jerk and able to hold speed of 60 kms per hour for a long time) tsitsu easily hunt animals like harelopes and porcippulas. Also tsitsu actively compete to other species of carnivores, for example, with zibetonyx. Due to superiority in strength they frequently take off prey of other predators. Even large predators finding themselves in position “two or three against hundred” are compelled to concede the prey to aggressively attacking tsitsu pack.
Similarly to Holocene hunting dogs tsitsu nurse even old and ill individuals, bringing food to them. The pack lives in the wast territory, but in the evening after hunting adult individuals hasten to shelter – colony numbering up to several tens of holes dug in soft ground. These dogs rear young growth in holes, and individuals do not take part in hunting – old or injured animals – look after posterity. For communication at the large distances tsitsu uses sounds. The sound repertoir of tsitsu is diverse and includes howl and bark of varying tonality and duration, and also yelping and growl. A characteristic sound of night steppe is thin shrilly howling of the whole tsitsu pack.
Speed used in hunting has the return side – the organism of fast runner is used up in greater degree. Average life expectancy of tsitsu is about 15 years, but usually it is much less.

Savanna sab (Paralupus afrorientalis)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: savannas of Zinj Land.

Picture by sla8ca of "The Artist's diary" group

Picture by Wovoka

Having lost their main competitors – gray and red wolves and African wild dogs at the end of the Holocene and the beginning of the Neocene – jackals began to conquer the niche of large cursorial pack predator. But while they failed to do this in Eurasia and North Africa, then in Zinj Land and in South Africa they managed to increase in size and become peculiar analogues of the wolf. Savanna sab inhabits an isolated East African microcontinent (Zinj Land). It is a descendant of side-striped jackal (Canis adustus); the name is a word for a wild dog and a jackal in Ancient Egypt.
Body length is 95-100 cm, withers height is up to 50 cm, weight is 18-26 kg. Wool color is gray with longitudinal rows of darker spots on the sides. Occasionally, there are patches of white fur on the legs or tail. The muzzle is shortened, adapted to put strong bites. Wide ears with rounded tips serve for thermoregulation.
This species occupies a niche of large prey hunter. Its prey includes goatlopes of small and medium-sized species. More rarely, old, sick or injured individuals of larger goatlopes, or the old nunda, become its prey. This species does not disdain carrion, and often robs prey from predators of comparable size. Sab lives and hunts in packs of 5-12 adult animals. Quarrels are rare in their packs – a strict hierarchy is established between animals. Predators constantly move around the savannah following the herds – they have a number of temporary shelters that animals use when migrating. They chase prey in an organized manner, and there are always animals in the pack who did not participate in the prey stalking and are ready to join the hunt at the proper moment. Acting collectively, a pack of sab cuts off the intended prey from the main herd and drives it to exhaustion. Usually, large packs turn out to be more successful hunters.
Breeding season takes place in May-June. Established couples exist for years, and males usually only drive competitors away from their females. Battles happen very rarely; only young or widowed males quarrel over females. Also, single males who challenge pack members pose a certain threat to relationships inside the pack.
Pregnancy lasts 60-65 days; there are 5-10, sometimes up to 12 pups in the litter. Abandoned burrows are used to raise offspring, being deepened and expanded if necessary; less often, a pair of sabs digs out their own one. Most often, a dominant pair breeds, and in large packs the second pair in the hierarchy also breeds. For the first 2 weeks after giving birth, the pack feeds the mother, and later her cubs also. In January and February, the juveniles are already quite independent and often leave the pack, forming bachelor groups. Usually males leave their parent packs; sometimes they take the females away from their own pack, or, more often, from any other pack. Maturity occurs at the age of 1.5 years; life expectancy is 12-15 years.

Picture by Cossus

A larger species, forest sab (Paralupus sylvaticus), lives in the jungles of Zinj Land. It is the size of a Holocene wolf and feeds on large prey, partly competing with nunda. Packs of this species are smaller, consisting usually of 2-3 pairs of adults and their offspring. The hierarchy in groups of this species is less strict, and subordinate pairs also produce offspring, although in smaller numbers compared to the dominant pair.

Zubri’ (Xenolupus asiaticus)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: steppes of Central Asia.

Picture by Cossus

By the beginning of the Neocene, canids had actually lost their most successful species. The reason for this was the destruction of habitats, the undermining of the food supply and overhunting. After the human disappearance, populations of large species appeared fragmented, which doomed them to gradual extinction. Only the most unpretentious smaller species – jackals, coyotes, arctic foxes and some other foxes – have successfully recovered their populations. During the Ice Age, the descendants of these species even experienced a certain flourishing. Melting of the glaciers and shrinking areas of grassy plains have led to a reduction in the diversity of canids. In particular, of the Eurasian descendants of the coyote, only one species remained – of hybridogenic origin, having an admixture of jackal and dog genes. But jackals have achieved great success in the Old World. There are even several large species among them, one of which is zubri’ (the name means “dhole” in Buryat), a descendant of golden jackal (Canis aureus).
Body length is 90-110 cm, tail length is 26-35 cm, and the height at the withers is 60-70 cm. Wool color is brown with a yellowish tinge on the sides and a light belly. On the back, as a rule, there is a darker “shabrak”. Head is relatively large, with very strong jaws. Ears are pointed and mobile.
Zubri’ lives in small family groups of 7-8 individuals: a breeding couple and their cubs of the past two years. In winter, these groups unite into packs of 25-30 individuals, among which pairs of young animals can form. This species is an active predator, hunting a variety of prey – from jerboas to cubs of large animals. Due to its agility, an adult animal can catch a flying bird in a jump by grabbing it with its mouth or knocking it down with its paw. In winter, a large zubri’ pack successfully attacks the lesser obda. When hunting large prey, they combine ambush hunting with driven hunting – some animals drive prey in the direction of others who are in ambush. Zubri’s family life is connected with burrows, their own or taken from other animals. On the territory of the family group, there are several burrows located in groups – the burrow of an adult couple and individual shelters of young animals. In winter, a joint pack hunts together in the territories of its constituent family groups.
The rutting season begins at the end of winter. At this time, conflicts occur between bachelors, or between males who have lost a female. “Married” male, with the help of its female, easily drives away all applicants. In the established pair, during the rutting season, both animals play like puppies: chasing each other, jumping, barking – this is how reduced courtship elements manifest themselves. After 2.5-3 months, 3-4 puppies are born in one of the burrows. For the first week, the female is fed by a family group, then the female begins to leave the litter and joins the hunting group, and the puppies are guarded by one of the young females. At the age of 5-6 months, cubs learn to hunt with adults, and at 15-18 months, young animals are expelled from the clan if its numbers are large. Usually, the females leave the clan, and the males are related by blood. Young animals easily mix with their peers and form new groups, which can form independent packs or join existing ones. Zubri’ becomes mature at the age of 2.5-3 years, its life expectancy reaches 18-20 years.

Jerkul (Xenolupus altaicus)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: mountains of Central Asia.

Picture by Cossus

Most Neocene canids, as in the Holocene, inhabit open spaces. But if in the Holocene it was the result of natural evolution, and the most successful of them lived both in the open areas and in the forests, then after the era of human domination the situation changed. The decrease of the food supply, overhunting and destruction of habitats have undermined the numbers of the most successful canids: wolves, African wild dogs and dholes; the numbers of foxes have decreased. During the Ice Age that marked the end of the Holocene, diverse canids populated the open plains of the new world. But later the glaciers retreated and the forests began to return. Many of the canids retreated along with the plains. The descendants of the foxes, who lived in the temperate forests, came out onto the plains on their own, but did not completely leave the forest habitats. Other canids that had developed the plains tried to return to the forests. Not everyone managed to do this: in Siberia it is waheela, in North America it is a hyaena-toother, and in Altai, Sayan, and Tien Shan mountains there lives jerkul (name of red wolf of the Evenks/Tunguses) – a descendant of golden jackal (Canis aureus).
Body length is up to 110 cm, tail length is 30 cm, and the height at the withers is 55 cm. Legs are relatively short, which allows the animal to move easily on the mountain slopes. Wool coloration shows great individual variability: the main color is brown, and ocher-red, gray and black without white markings are less common. Belly has slightly lighter color than back. Head is large, with a massive muzzle. Ears are wide and covered with thick short hair on the outside.
This species keeps in small family groups: an adult pair and cubs of their recent litter (5-7 individuals in total). A pair of adult animals controls the territory of the clan and marks its boundaries with urine. In winter, jerkuls are more tolerant of their relatives and can gather in packs numbering 20-30 individuals. Then they are able to overcome many large animals living in the neighborhood. Their usual prey is medium-sized animals: large rodents, stoneloppers, trunk boar juveniles, and in winter, old and sick adult trunk boars. A hunting animal can catch a flying up bird in a jump, or sneaks up to it. The animals often eat the remains of the prey of large predators – tanooka and menkw – living in the neighborhood. Jerkul avoids the latter one: even in winter, a hungry pack waits for it to get enough. But menkw weakened by illness or old age often becomes their prey; a healthy animal will kill a jerkul caught near prey. These predators hunt by driving prey; stoneloppers and porcippulas are often ambushed – some individuals hide in front, the rest ones drive prey towards them. Each family couple owns a territory of 15-20 square kilometers. The pack hunts on the territory of the groups it consists of.
Jerkul is in heat from the end of January to the middle of March. Breeding pairs form for life. In the established couple, the manifestations of marital behavior are limited – this is howling together and slight biting the partner’s shoulder. Competitors are driven away from the pair’s territory by their joint efforts.
Pregnancy lasts 63-65 days, and 3-5 puppies are born. For the first 10-15 days, the mother stays in the burrow with them, and the male and the yearlings feed her. Young jerkuls try to come out of the burrow at the age of 1.5-2 months; the older young begin to hunt with the adults. Shortly before the next litter leaves the burrow, they become independent, but their parents tolerate their presence for another year while they help provide food for the new litter. Females reach sexual maturity at the age of 2 years, males – being 3 years old. Life expectancy is 12-15 years.

Chootie (Chuti chuti)
Order: Carnivors (Carnivora)
Family: Canids (Canidae)

Habitat: salt swamps of Mediterranean lowlands.

Picture by Cossus

Initial image by Odin, the forum member

For many mammals hot salt swamps have arisen in saline desert replaced former Mediterranean Sea are the most improper place for life. Any unadapted animal casually got in these places is doomed for death within several days. In border areas of Mediterranean swamps frequently there are corpses animal, lost from thirst and overheat. Salt can keep their bodies for long years, impregnating them when wind wears out the dead animals with salty sand and dust. But some mammals could adapt to these severe conditions, and there are even species prospering in this inhospitable environment. Usually rodents make the majority among champions on survival, but representatives of predatory mammals also live in severe desert at the border between Europe and Africa. They are descendants of the fennec fox (Vulpes zerda), the small big-eared fox. This tiny Holocene canid, at which the significant part of diet was made with insects, was perfectly adapted to survival in extreme conditions of critical shortage of water resources. Holocene fennec foxes could live without water for some days even in conditions of heated deserts of Holocene North Africa. Therefore right at the beginning of Neocene descendants of fennec fox could colonize droughty open spaces of Mediterranean lowland while the rests of sea still existed in hollow between continents. In due course descendants of fennec fox turned even smaller and passed to completely insectivorous diet, having formed a separate fennecine subfamily (Fennecinae) within canid family. The fennecine subfamily includes one genus Chuti and two species – chootie and adjule. Chootie is a typical species of genus. It is a predator of very unusual shape: a tiny mammal which length does not exceed 12 cm including tail. Thus ears of this one have kept the same proportional size relatively to body size, which was at fennec fox, its far ancestor. Running chootie from apart looks like any rodent, and its belonging to predators can be defined only at more attentive survey.
Chootie has rather short legs in comparison with its ancestor, and shorter tail. Loss of water and overheating are the basic dangers at life in salt desert. Chootie escapes from overheat with the help of wide auricles penetrated with blood vessels and helping to radiate superfluous heat. Its wool is dense and velvety despite of a hot climate in its habitat. Such wool provides protection from overheat to skin of animal. Colouring of chootie is camouflaging – reddish or yellowish. In the populations living in saline soils of Mediterranean hollow, white and light grey color variations are most usual. Chootie avoids loss of water due to habit of life and features of physiology. This animal is active at twilight hours and in dawn time, spends its day in one of regularly visited shelters at its territory, and sleeps within some hours at night in temporary shelters. Kidneys of this animal work very effectively, and urine has very high concentration of nitrogenous substances.
Chootie is extreme cautious mammal relying on sharp hearing and keen sense of smell in detection of danger. Out of breeding period lonely chooties constantly migrate from one small source of fresh water to another. Moreover chootie receive a significant part of moisture from food. The basis of chootie diet is made of insects and other small invertebrates. The liver of animal effectively destroys some poisons of organic origin, therefore chootie can eat poisonous beetles, millipeds and spiders entirely. Chooties become prey of reptiles and birds of prey. Despite of adaptations to life in desert, chootie always faces real danger to die from dehydration. In dust storm animals may simply choke with salty dust if the shelter can not protect them.
The care of posterity at this species is original. At males long fur jabot grows on breast soon after pairing. The wool in this jabot has one feature – at contact to water it is capable to accumulate and keep moisture in significant amount. While the female feeds cubs, male searches for water. At night stones in desert quickly cool down, and to morning plentiful dew accumulates on them. Male literally wallows on surface of stone and creeps on it on belly, carefully absorbing dew by wool. When he comes back to the female and cubs, they lick off this moisture from fur jabot, receiving thus the additional portion of water. Within one year the female has time to draw up to three litters of 4 – 5 cubs in each. Like all animals of small size, chootie grows quickly: the month-aged cub already reaches the size of adult individual and becomes independent. And five month old animals can raise their first litter. More successfully chootie breeds in winter and in the spring when from the Alpes and Atlas Mountains streams flow down to the Mediterranean hollow, and air is damper. In summer animals do not breed, and if the female is pregnant, embryos are “conserved” at the early stage of development, or simply resolve.
Life expectancy of chootie makes about 7-8 years.

Also in eastern part of Mediterranean swamps and at the territory of former coast of Asia Minor larger species lives – adjule (Chuti adjule). Its adult males reach the size up to 20 cm. It has similar biology, but can attack small reptiles occasionally. This species always keeps in pairs and lives near to constantly existing sources of water. Colouring of wool is grey with black strip along the back.

Nuvisha (Xenocanis nuvisa)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: North America, plains, woodlands, foothills.

Picture by Cossus

In Neocene, the canid family retained significant diversity in its ancestral homeland of North America. Here, canid species have evolved, that occupy a variety of ecological niches – fast-running inhabitants of the plains, massive carrion eaters, and even short-legged burrowing species. Specialization helped them to get rid of competition from the descendants of foxes, but the stem line of the non-specialized “coyotes as themselves” disappeared. They had been replaced by the descendants of kit fox (Vulpes macrotis), which occupied such an advantageous place in the ecosystem. While losing to each coyote descendant taken alone in terms of specialization, they benefit from all of them simultaneously in terms of ecological plasticity and the ability to live in various of conditions.
Nuvisha (in Native American mythology, “nuwisha” is coyote shapeshifter) occupies a very advantageous ecological niche of the Holocene coyote, having settled throughout the continent in temperate and subtropical climatic zones. This animal avoids continuous woodlands, clearly preferring a “mosaic” landscape, where shrubs and fragments of forested area alternate with areas of grasslands. This species is also found in woodlands and foothills.
Nuvisha is much larger than its ancestors and reaches the size of a Holocene wolf, although it is shorter-legged: body length is up to 80 cm, tail is about 25 cm, and shoulder height is 40 cm. Animal’s fur is of sandy-cream color, darker on the back, and almost white on the belly. Sometimes there are variations of coloring – white spots on the chest, throat and tip of the tail, as well as “stockings” on the paws. The inhabitants of the more northern parts of the range are often darker, up to ochre-red color.
In its appearance, nuvisha resembles a large fox – the beast has an elongated muzzle and large rounded ears. Numerous vibrissae grow on the muzzle. Tail is covered with relatively short hair and looks thin compared to fox’s one.
Nuvisha lives in small family groups of 4-5 individuals. In the group, there is a breeding pair and their offspring of last year’s litter. Shortly before the birth of the new cubs, the male expels other males from the group. The attitude towards young females is more loyal: they stay in the group for the entire time of the rearing of young animals and leave the group only at the beginning of winter, when the animals begin to rut. These animals reach sexual maturity only in the second year of life, but in the first year they can take part in mating games, although they do not become pregnant.
Nuvisha is a burrow-dwelling animal that lives quite secretively. These animals are especially cautious in vicinities of their burrow, when the offspring are still unable to move to other places on their own. Nuwishas dig their own living burrows or expand the burrows of rodents. In the burrow of these animals, each adult occupies a separate living chamber, and only the female can live with her offspring in the largest chamber. There is also a special toilet chamber in the burrow, where adults leave their droppings by burying them in the ground. This behavior helps them hide their presence from stronger predators and possible prey. Far from the lair, nuvishas leave their droppings openly, only slightly covering it with ground. It is a nocturnal animal, but sometimes nuvishas are active during the day – most often if the night hunt was unsuccessful. The nocturnal lifestyle helps nuvisha avoid competition with other predators.
This beast feeds on various small animals: rodents, birds and large insects, as well as carrion and the remains of prey of larger predators. Sometimes nuvisha attacks the cubs of larger herbivores, usually deermaras or “true” deer.
Nuvisha breeds once a year. The rutting season takes place at the beginning of winter. At this time, the animals are very active and do not hide. Males bark drawlingly, calling for females, urinate on the ground and wallow in urine, thereby enhancing their smell. They chase in a whole group a female who has come to their voices and fight for the right to mate, standing on their hind legs and striking each other in the muzzle with their front paws. This is how only single or widowed males who are looking for a mate behave. After forming a pair, the female moves into the male’s territory and the pair jointly expands the territory, occupying part of the borderlands and driving back single neighbors. Males and females from established pairs bark together at night during the mating season and expel strangers from their territory.
In the spring, the female gives birth to offspring. Usually there are about 5 cubs in the litter – more often 3-5 ones, in particularly favorable years up to 7 pups. Very young or old females bring only 1-3 puppies. They spend the first days of their lives in the nest chamber; at the age of one week, their eyes and ears open, and two-week-old cubs come out of the burrow and begin exploring the surroundings of the burrow under the supervision of a “babysitter” animal.

Anteater Fox (Neootocyon insectophagus)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: southern and eastern Africa, savannas and woodlands.

Picture by Alexander Smyslov

The border of Neocene and Holocene epochs was marked with the mass extinction of various animal species and even familles. That included the extinction of Proteles cristatus, unusual predator from southern and north-eastern Africa, who was almost completely insectivorous. The human intervetion and new rivalring species caused the extinction of that insectivorous hyena. But that environmental niche hasn't stayed vacant for too long, as there were several applicants to fill it: in the North Africa it was grumbling ant-mungo from the family closely related to civets, while in the south it was the representative of another carnivorous family – the bigear fox (Otocyon megalotis) descendant – anteater fox.
It's a middle sized animal with thick fur (size varies from 80 cm to 1 m, weight - 6 -10 kg) and relatively long legs which is typical for most open environment animals. Thick fur saves the animal from the ants and termites' "soldiers" bites. Thick and shaggy fur of that animal has relatively monotone brown colour, with just the ears' tips being a bit darker. Nose, chest and neck have extra protection from insects, spiders and scorpions bites- unusualy dense skin. The vulnerable nose has extra protection- a small piece of cornual "armour".Unlike another 'anteaters' (Holocene true anteaters from Edentates Order and pangolines, Neocene echidnas, lizards and wormtonguers) its teeth system isn't reduced- it has plenty of sharp small teeth, resembling insectivors teeth a lot. Being very careful, anteater fox hunts only in twilight and in the night. In the day anteater foxes rest in selfmade holes or in the other animals dens. Very often they share their dens with armor-headed wart hogs for extra protection.
The sensitive ears of anteater fox are inclined a bit forward and down; keen hearing helps it successfully find insects even in deep darkness. Its paws aren't specialized simply for breaking termitarys, so the fox has to vary its diet, adding another invertebtates (beetles, spiders or ants) into it. Also its diet includes eggs and small vertebrates. One of the main alternate food sourses are locusts, who have survived all the ecological disasters on the border of Holocene and Noeocene. Its invasions are comparable to lemming invasions, and as regular in Neocene as it was in Holocene. To the anteater fox, it's just like lemming invasion to polar fox- it "forgets" about hunting in twilight only and hunts for the locust even in the daylight.
Just like their ancestors, anteater fox are monogamous. That is explained by the diet pecularities- they hunt for small preys so the nessesary population density just can't be reached. The female gives birth to 3-7 cubs but not all of them reach senior age, especially in dry lean years, when there's little food and all savannah inhabitants, including large predators, are starving.
The maximal lifetime of anteater fox is 10-15 years.
In the northeastern Africa, where the insectivorous enviromental niche is occupied by other animals, lives the anteater fox relative - coastal fox (Neootocyon oraannona). Its diet includes various seafood- shellfishes, dead fish, mollusks,which they gather during the falling tide. Unlike its southern relative, coastal fox body is more "foxy"- it has shorter legs and smaller ears. The lower part of coastal fox' acoustic duct is protected by skinny valve to prevent water from coming into ears. The fur is short and hydrofuge (especially on lower body half). Despite living at the seashore, coastal fox is not a good swimmer. It prefers to search for its food on the littoral fringe, but sometimes comes to feed before the falling tide ends or stays on the littoral fringe till the rising tide starts. The fur of coastal fox is more light-colored that the one of anteatrer fox- it's yellow with grey shades. The fingers on the paws are mobile and broad-placed, which helps the coastal fox to run on the sand with ease as well as hold its preys. The coastal fox is very careful animal, who is very tolerant to its relatives. Several couples of those anmals can feed on the littoral fringe simultaneously without disturbing each other, and fights rarely happen during the feeding.
The breeding and home life resembles those of an anteater fox. Coastal fox makes its dens at coastal rocks or at the bushes (higher that the highest rising tide mark). The maximal lifespan is around 12 years.

Dire fox (Dromovulpes ferox)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: Southern and Western Europe south of the mountain belt, woodlands and shrubby thickets.

Picture by Cossus

Small representatives of canids quite successfully survived the era of anthropogenic pressure and climatic changes at the turn of Holocene and Neocene. In the new conditions, they gave rise to new large species. The second heyday of canids occurred during the Ice Age, when large packs of descendants of coyote and jackal hunted in the tundra steppes of the Northern Hemisphere, and with climate change in the Neocene, they retained their positions. In the forests of the temperate zone of the Northern Hemisphere, foxes have gained an advantage: in North America, it is lynx fox, and in Europe it is dire fox, a descendant of red fox (Vulpes vulpes) of the Holocene epoch.
Body length with tail is up to 1.7 m, weight is 65-67 kg. Dire fox is a long-legged cursorial animal that lives in sparse forests, a relative of grass fox from the dry regions of Western Europe and North Africa. This species differs from its steppe relative by its slightly more massive physique and preferred habitats. Wool color is reddish-gray, lighter in winter. Occasionally, individuals of pure ochre-red and straw-yellow color are found. Ears are black on the outer side with white tips. Males are slightly larger than females. This species is monogamous, pairs are formed for life. Adult animals hunt together, less often together with grown-up cubs. The couple owns an area of 25-30 square kilometers. The usual prey is medium-sized mammals: large rodents, harelopes, and sometimes cubs of large animals. This species does not disdain carrion and the remains of prey from large predators. In summer, this animal can eat berries or fruits, but it does so less often than its ancestor.
The mating season runs from the end of February to the beginning of April. The male searches for a convenient place to dig a burrow, where he leads the female. There are always several holes in the territory of a pair of dire foxes: main one and 3-4 spare ones. In different years, cubs are born in different burrows; sometimes, adult animals dig a new burrow afresh. Often, the male has to protect both the female and the burrow from young bachelor males invading the couple’s territory. Intraspecific brawls often end with wounds and lacerated ears.
Pregnancy lasts 62-65 days, and there are 2-5 puppies in the brood. At the age of one month, they already receive a regurgitated food from adults as complementary food, and at a month and a half they taste adult food. At the age of 2.5 months, young dire foxes learn to hunt with adults and stay with them until the end of autumn. In December and January, they are already independent. As a rule, they are driven out by the male. Young animals reach sexual maturity in the second year of life, with a life expectancy of 12-15 years.

Lynx fox (Megacyon feliformis)
Order: Carnivors (Carnivora)
Family: Canids (Canidae)

Habitat: North America, forests of temperate zone.

Picture by Alexander Smyslov

As against larger wild dogs, such as wolves and African hunting dogs, smaller canid representatives had quite safely gone through both anthropogenous pressure, and climatic changes of the boundary of Holocene and Neocene. These animals – jackals, coyotes, foxes and even small varieties of feral domestic dogs – were successfully fixed in ecological niches of small and medium-sized predators, having caused new species in due course. So, in Siberia waheela, the descendant of polar fox, had evolved and in South America the feral representatives of domestic dogs became wild pack predators again, despite of approximately 16 – 20 thousand years of life near people.
In North America lupardus is one of the largest and widespread wild canids became ecological analogue of cheetahs, running felid representatives. It lives in prairies, but in areas where open spaces are replaced with forests and groves, other canid species live – the descendants of red and grey foxes.
The grey fox (Urocyon cinereoargenteus) lived in North and Central America to the south from Canada, and had, as well as other foxes, good amount of hardiness and ecological flexibility. In Neocene, despite of slightly increased pressure from the side of more progressive descendants of red foxes and coyotes, the grey fox quite safely evolved into new canid species – the lynx fox. In forests it occupies the become empty ecological niche of Canadian lynx which had become extinct in Holocene.
Lynx fox is very large animal in canid standards: large самец can reach height of 130 cm rearing on hind legs of about 40 cm long. Weight of animal quite corresponds to growth – large foxes may reach weight of 60 kg: as much, as Euroasian waheela weighs. But, as against waheela, lynx fox can not change wool color in winter and in summer: the year round this animal has silver-gray fur which appreciablly turns white on the tip of tail. At adults males “collar” of pale-yellow fur grows on neck. On back of these animals there is an indistinct spotty pattern. It is clearly expressed at young individuals, and it helps them to escape from predators, hiding among grass and foliage. In course of growth animals lose this pattern, but at the southern borders of the area where more evergreen plants grow and winter is snowless, up to a fourth part of individuals keeps spotty colouring in adult condition, and separate populations include almost exclusively spotty individuals.
The tail of this fox is long and thin – it serves as the balance weight at the movement on trees. Carpal and talocrural joints of animal are mobile and allow to hand and foot to turn on small angle – it helps lynx fox to climb on trees better.
Muzzle of this animal is short and has large canines. However, canines serve mainly for demonstration – the angry animal starts “yawning”, turning to the opponent and widely opening mouth. Auricles are rather large, mobile, peaked, and have small hair brushes on tips.
Despite of the growth and impressive canines, lynx fox has rather peaceful behaviour and is not squeamish in feeding: it is omnivorous and in autumn, in the time of fruiting of wild berries and trees it almost completely passes to vegetative food. It eats the greatest amount of food of animal origin at the end of winter and in early spring when stocks of vegetative forage accessible to this animal are exhausted. At this time lynx fox can even eat carrion. It also has kept abilities of ancestor to tree climbing and is quite capable to find prey and shelter for rest on trees. Forage of animal origin of this animal includes various animals and birds, but especial frequently it hunts hares, as well as its ecological prototype – Canadian lynx. The fox is afraid only of few animals: berls, huge mustelid representatives, and also of missopeho, Neocene American saber-toothed cat. But due to its secretive twilight habit of life and ability to tree climbing lynx fox almost does not face with these predators.
As against others large canids, lynx foxes do not form family groups. Females raise cubs independently; usually there are from 1 to 3 cubs in litter. They meet males only during a courtship season. It takes place at the end of winter; that time males arrange long duels, rising on hind legs. Also the winner male pursues the female for some time, estimating her force and the relation to him. Usually the female shows resistance only right at the beginning of courtship, if the male is pleasant to her. Avoiding male, the female, on the contrary, shows long resistance and tries to come nearer to other males which perceive her persecutor as the contender and attack him.
Voice of lynx fox is long lingering bark which may be heard at the great distance. With the help of voice animal declares rights to territory and calls the courtship partner. Cubs have thin squeaky voice and can utter sounds similar to twittering.
Usual life expectancy of lynx fox is about 10 – 12 years.

Aoskiar (Megacyon aoskiar)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: deciduous forests and woodlands of North America.

Picture by Cossus

By the beginning of the Neocene representatives of North American canids were represented for the most part by descendants of the coyote (Canis latrans) of the Holocene, by predators of medium and large sizes. The only exceptions are waheela, a descendant of the arctic fox, and various descendants of grey fox (Urocyon cineroargenteus), one of the most unusual canids of the Holocene. One of its descendants, the lynx fox (Megacyon feliformis), has changed relatively little and in many respects is similar to its ancestor, only changed by its larger size. But another descendant of the gray fox, the aoskiar, is markedly different in its appearance, as well as behavior.
The aoskiar is quite a large beast: the height of an adult at the shoulder is about 90 cm, a body length of about five feet, and a tail length of about half a meter. In its proportions this animal resembles a beagle dog, and only the head, and especially the whiskers and ears, retain the features of a “portrait likeness” to the fox’s ones. Its eyes are greenish-yellow, its eyebrows are bushy and light colored, at a sexually mature male on the neck a thick “beard” grows. The hair color is usually gray, almost monochromatic, lighter on the belly. Northern populations of aoskiars differ in darker hair compared to southern ones; sometimes some of them are melanistic. In southern populations “blondes” having straw-yellow hair are occasionally found.
The aoskiar is a terrestrial carnivorous mammal that eats very little amount of plant food, unlike the related lynx fox. It has weak jaws, not adapted for chewing, but armed with teeth with sharp cutting edges. It is an active predator that can hunt for a variety of prey. Its diet consists of small and medium-sized rodents, lagomorphs, juvenile ungulates, terrestrial birds and their chicks, frogs, small non-venomous snakes and lizards, various insects and carrion. Due to the light constitution and good running abilities this animal is capable of preying on the swiftest animals, driving them to exhaustion. In this regard, the competitor of the aoskiar is the lupardus, but these two species rarely compete as the aoskiar is larger and preys on larger animals. In addition, the aoskiar prefers a “mosaic” landscape with thickets of shrubs and trees, while the lupardus inhabits plains, overgrown with grassy. Aoskiars themselves are often victims of waheelas, berls and other predators which ravage their dens.
Aoskiars live alone or in pairs or small packs (3-8 individuals) whose members are usually connected by family relationships. They hunt large prey, combining hunting from an ambush with a running hunt – one animal drives prey towards others, hidden in an ambush. Family life of aoskiars takes place in a den (usually a wide burrow or a hole under the roots of a tree), where adults raise pups (there are typically 2-4 puppies in litter). Both parents take care to puppies, and sometimes they are helped by “nurse”, the grown up cub of the previous litter or a subordinate female (usually the sister of dominant one).
Aoskiars are usually monogamous, but sometimes one male has two or three females. In this case, offspring appear only at one dominant female. The struggle for the establishment of domination relations occurs only if the females are unrelated to each other. Courtship at aoskiars occurs in late winter, and the posterity is born a few months later at the beginning of summer.
Aoskiars are cautious animals, when they meet with enemies they prefer not to fight, but to hide in the forest or scrub. They enter an open confrontation only when there is a threat to their offspring, and inflict deep bites on the aggressor. The adaptation to rapid running largely affects the physiology of animals: due to frequent exposure to intense physical stress the life expectancy of an aoskiar is no more than 8 – 10 years.

Fish-eating fox (Vulpinia piscivorus)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: eastern North America, shores of Mishe-Nama lake and rivers flowing into it.

Picture by Cossus

Neocene appeared to be a controversial epoch for the canid family. On the one hand, at the end of Holocene, the largest wild canids of the human era, gray wolf in the Northern Hemisphere and African wild dog in Africa, disappeared. On the other hand, smaller species such as jackals, coyotes and foxes continued to flourish, and underwent a rapid evolutionary process in Early Neocene, giving rise to a variety of descendants. Some of them, like waheela and lupardus, have become quite remarkable social predators, but among the Neocene canids, there are also smaller and solitary species that do not form permanent packs, such as various species of North American foxes.
One of these species is fish-eating fox, one descendant of swift fox (Vulpes velox). It is a medium-sized fox – the size of a large cat, with wider paws and thin tail. It resembles its ancestor in appearance – reddish-gray skin (brighter on the sides, darker on the back, often even a black stripe along the backbone is present), a light belly, a light semicircle on the neck in front, and a dark half mask on the muzzle. Wool of fish-eating fox is thick and water-repellent, like the wool of an otter or a mink of the human era, and in general this fox swims better than most canids.
Fish-eating fox specializes in food searching in water, but it does not only feed on fish. Although it swims well, it usually lurks its prey – small and medium-sized aquatic animals – on the shores. Aquatic animals usually see quite poorly, and the fox often notices them before they see it, after which it usually jumps into the water and catches prey – small fish, frogs, salamanders, etc., after which it hurriedly gets ashore so as not to encounter a large underwater predator. This animal is cautious and timid, so it prefers to avoid large carnivores both in water and on land. The only exception in this regard is the local species, the dwarf gannetwhale: fish-eating fox often visits colonies of these birds in search of carrion, scraps and prey accidentally regurgitated by birds. It does not attack healthy birds – their forces are too unequal. Occasionally, it manages to snatch a live or dead chick from the colony. Jaws are relatively weak in this animal.
In winter, the behavior of fish-eating fox changes somewhat – it needs to forage more actively, so it migrates either to colonies of gannetwhales, where it is easier to find food, or to areas where the water does not freeze. This animal is not strong enough to break through thick ice or maintain an ice-hole during the winter, but it can use natural ice-holes to dive under water for prey, however, very briefly (for about 3-4 minutes) and usually in pairs, rather than alone. By winter, the animal grows thick fur on its paws, especially on its digits.
The mating season of fish-eating fox begins at the end of winter, around February. Males fight for females, and do it quite violently; the female chooses the strongest one. A few weeks later, 3-4 cubs are born (sometimes 1-2 or 5-6). They are raised by both parents; although this canine is not pack species, breeding pairs are often formed for life.
Fish-eating fox can live for about 15-20 years, but most of them die earlier, from larger predators, diseases and winter starvation, especially in the first years of independent life.

African tufted fox (Dromovulpes africanus)
Order: Carnivors (Carnivora)
Family: Canids (Canidae)

Habitat: North Africa, savannas and woodlands.
During Holocene epoch the common red fox (Vulpes vulpes) lived in northern hemisphere everywhere from Europe through Asia up to North America, being one of the most widespread smaller canids. Its well-being was directly connected to anthropogenous pressure which had destroyed or strongly reduced number of larger predators, having given to foxes more freedom for existence and having given new habitats. Red fox existed successfully in landscapes changed by people that had allowed it to keep large number and wide area.
But the situation had changed in Neocene. People had disappeared, and red foxes had lost the advantages connected to development of anthropogenous landscapes. Some waves of ice ages had thrown heat-loving foxes farther to equator therefore this species of animals had disappeared in New World absolutely, and in Old World it had conceded northern part of the area to polar foxes and to waheelas, their descendants. But in new habitat – in Africa and southern Asia – foxes had quite accustomed, had evolved to new species and even had returned to Europe as it was made by grass fox, solitary running predator of savannas and woodlands. But nevertheless it is a rare case – the majority of its relatives lives in warmer parts of the world.
African tufted fox is a species related to grass fox, but distinguished from it with a number of anatomy and behaviour features. First, it hunts not only alone, but also in pairs. In this case one animal exhausts prey, and the second one jumps out from an ambush for it and puts the final impact. Sometimes the grown up cubs help thus to parents and at the same time study hunting methods. However, as against the grass fox, tufted fox usually accelerates speed no more than 18 – 20 kms per hour, but at the same time it has the great endurance and is able to pursue prey for a long time. Moreover, rear legs are longer and stronger a little bit than front ones, and it allows the fox to jump on stones and low-growing trees having curved trunk in order to leave from a pursuit or to catch small prey.
Second, tufted fox is colored conservatively enough. It has monophonic sandy color (there are also darker individuals) with lighter belly and tail tip, and also with dark “stockings” on legs. Males additionally grow a crest or a forelock – a bunch of longer and rigid hair on head between ears, which condition shows age, health and force of its owner. At females wool on head is only slightly lengthened, and only at the strongest and most aggressive individuals testosterone surplus results in formation of small hair cop.
Tufted fox is an omnivore. It usually eats carrion, and also various rodents – down to cubs of huge grasscutter rats. Attacking less dangerous animals, like kangoohoppers, this animal can chase also healthy adults. Steppe harelopes especially suffer from it – tufted foxes eats more than 20 % of their young growth, despite of all attempts of parents to protect the posterity. Usually hunting foxes separate young animal from herd and drive it in savanna, not allowing it to have a rest. After one hour of such pursuit one of animals snatches on it and kills, biting through the neck. Also tufted fox ravages nests of small birds and eats various reptiles, but at the same time willingly eats various ripe fruit and graminoids at the stage of milky ripeness.
At the same time tufted foxes are objects of hunting of larger predators. Crocoturtle sometimes catches them at the watering place whereas barbed herzogcats sometimes purposefully hunt these animals, considering them as food competitors and danger to their posterity. Tufted fox prefers to avoid furiobaboons and other monkeys living in groups though sometimes the strong individual can kill the young monkey. But in this case foxes quickly leave a place of hunting as the flight of monkeys represents force which is insuperable for foxes.
Tufted foxes breed once a year, from December to January. Female’s heat lasts for some weeks. The animal notifies on readiness for pairing by the shrill squeal which is a little bit distinct from usual bark of these animals. The voice of the female involves several males. They actively compete for the right of pairing; showing the crests to each other in the beginning, and then rising on hind legs and “boxing” by front legs to each other’s muzzle. The strongest and hardiest animal wins, as a rule. If male has found the female in loneliness, pairing usually begins after long and persevering courtship when male cajoles the female actively, and sings the “serenade” to her, uttering the sounds similar to grumble and cooing.
In some weeks after pairing the female brings posterity – from 5 up to 10 cubs. They are born small, almost blind and covered with white-yellow fur, but within several weeks at them eyes open and teeth start to appear. At bi-monthly age cubs leave shelter and start to learn the world around. At the age of half-year they are already capable to follow parents for hunting, and by the end of the first year of life they are already quite independent. At the second year of life the female brings posterity the first time. General life expectancy of tufted foxes is from 8 up to 13 years.

Kurilean aglah (Thalassocanis ostreophilus)
Order: Carnivores (Carnivora)
Family: Canids (Canidae)

Habitat: Big Kurils, Kamchatka coast, shores of the Sea of Okhotsk.

In Early Neocene, small and less specialized animal species fully realized their evolutionary potential. Their descendants show specialization in a variety of habitats and diets. One of these species is the raccoon dog (Nyctereutes procyonoides). Its large carnivorous descendant, the giant tanooka, lives in the forests of northern Asia. And Pacific coast of Asia and on nearby islands are populated by Kurilean aglah – another descendant of the raccoon dog, similar to the fossil Kolponomos sea bear (“aglakh” – “sea beast” in Aleutian).
Kurilean aglah has a physique significantly different from its ancestor. It is a large animal with a body length of about 140 cm and a tail of up to 60 cm. Aglah has a massive build, shortened and almost plantigrade paws with widely spaced digits connected by a swimming membrane. Large claws are used for food getting and help to cling to the sea bottom to withstand the waves. This animal swims and dives well, holding its breath for 10-12 minutes. Under water, the shortened ears of the animal are closed by skin folds.
The animal’s fur is thick and velvety, gray in color with lighter irregular spots. Legs and muzzle are darker, of brownish coloration; a dark brown stripe stretches along the back, and “sideburns” of elongated white fur grow on the cheeks.
Aglah feeds on benthic organisms with a hard shell – crabs, mollusks and sea urchins, occasionally eats starfish and slow-moving fish like gobies and flounders. If aglah catches seabirds, it eats them along with the bones, leaving only feathers from the prey. Due to the peculiarities of the diet, aglah’s jaws are very massive and shortened, and the masticatory muscles are well developed. The molars have a thick layer of enamel, and the incisors do not stop growing for a long time – they begin to wear out only in old animals.
Aglah usually searches for crabs and other animals by turning over stones. Underwater, the animal chases startled fish, but prefers to catch those that swim slowly and reluctantly. Aglakh also detaches from the rocks and algae the mollusks attached to them. Among echinoderms, aglakh prefers species protected by a shell or a small number of spikes, and clearly avoids long-spiked sea urchin species.
This species lives in small groups consisting of several breeding pairs. Family members take care of each other and care for their offspring together. The den of these animals is a hole dug in the ground or a natural shelter among rocks, which is lined with grass and dry seaweed. There are usually 4-5 cubs in a litter, which are born in early summer. Newborn cubs are blind and deaf, but they are covered with thick fur. Their coloration is dark gray. During the summer, they reach about half the weight of an adult individual and become completely independent by mid-autumn. Young animals quickly leave their parents and become sexually mature at one year of age. The life expectancy of this species reaches 12-14 years.
Further south, Japan Archipelago and Korean Peninsula harbor a close species, Japanese aglah (Thalassocanis nipponicus). It is a smaller animal, up to 150 cm long with a tail. This species has a darker coloration, more similar to the juvenile coloration of Kurilean aglakh, and the head of an adult animal remains black for life. White “sideburns” and a white spot on the chest stand out against this background.
The Pacific coast of North America is inhabited by Aleutian aglah (Thalassocanis gracilis), characterized by a more elegant build and a light coloration – gray with a white spot on the throat and lower jaw. This species has a dark muzzle and a black tail tip. Aleutian aglakh has weaker jaws and feeds on bottom-dwelling fish and mobile crustaceans such as shrimps and crabs. On the southern coast of Beringia, the ranges of Aleutian and Kurilean aglahs overlap, but these species do not compete due to differences in diet.

The idea of the existence of this mammal species was expressed by Carlos Pizcueta.

Picture by Amplion

At the boundary of Holocene and Neocene the mass extinction took place. It had influence at plenty of animals and was caused by human activity and reduction of territories, suitable for existence of normal populations of large animals. Bears also had died out. In Neocene animals of other families started to occupy an ecological niche of bears. In Southern Asia their place was occupied by viverrid descendants and in Central and East Europe by bearaccoons, descendants of raccoons. At the north of Holarctic niche of bears was occupied by large mustelids, berls, and also by animals of new Neocene family of carnivores – bear-like dogs (Prolesnyctereuteidae) separated from true canids. An ancestor of this family was a raccoon dog (Nyctereutes procyonoides), medium-sized unpretentious omnivorous canid. Eventually descendants of raccoon dogs had grown larger. Similarly to their ancestors, raccoon dogs (and also similarly to bears), the majority of bear-like dogs run into hibernation; this feature has allowed them to settle at the north of Eurasia remarkable in severe snowy winter. The family includes one genus (Tanuka) and two species. The largest species is giant tanooka. The weight of females usually reaches 500 kg, males – up to 600 kg; some individuals in northern part of area can grow to 800 kg. Thus, giant tanooka can compete to South African awfulest marafil for the right to be named as “the largest representative of carnivores order in Neocene”.
By appearance giant tanooka resembles a hybrid between bear and fossil predator Amphicyon. Because of rather short fingers and toes animal looks almost plantigrade. Fur of tanooka is brownish, spotted with numerous albesent and black spots on sides, shoulders and hips. Animal has very big claws, but, similarly to the ancestors, raccoon dogs, tanooka can not climb up trees. This animal runs slowly, but can make far passages for food within the borders of its territory.
Similarly to Holocene bears, giant tanooka is an omnivore actively consuming both vegetative and animal food. In spite of the fact that giant tanooka is a predator nevertheless, it prefers not to hunt itself, but to play a role of scavenger or to take off prey of other predators. Giant tanookas very often track down Siberian sabertoothes, but not as prey, but as original “suppliers” of food. After their successful hunting tanooka eats up numerous uneaten rests of their prey. Frequently (especially in autumn, right before hibernation) giant tanookas attack waheela packs, taking off their prey. If the autumn was poor in food, tanooka trying to take prey may risk and attack even the lonely berl. As against the berl, giant tanooka is active only in rather warm season. In winter, similarly to its ancestor, raccoon dog, giant tanooka runs into hibernation. In spite of the fact that giant tanooka is heavier than berl, it is not a dominant predator because of three factors: first, its population is extremely rarefied (the average territory controlled by one individual is about 2 – 3 thousand square kilometers), second, in winter it runs into hibernation, and, thirdly, tanooka is more omnivorous scavenger, rather than active predator. Besides in summer and in autumn more than 60 % of its diet the vegetable food makes. The main contender of giant tanooka is berl. Tanooka does not bear the presence of berl in its territory and relates to it agressively: it will try to banish berl, using the size and force, and also to kill it if the opportunity will appear. In a case if tanooka meets berl female with cubs, it will try to kill cubs by all means, despite of all attempts of berl female to protect them. In such situation tanooka will attack berl cubs and female protecting them, despite of repulse which large predator can render it. In winter the situation frequently changes to opposite one. From time to time berls attack tanookas in hibernation condition right in their dens. To tell the truth, it finishes with berl victory not always. Winter sleeping of tanooka is not too deep, more similar to bear ibernation. If tanooka will have time to wake up during such attack, it will kill or will seriously cripple the attacking berl most likely.
Because of great rarefaction of populations at giant tanooka the original courtship behaviour had evolved. Closer to approach of courtship season tanooka males actively mark borders of their territory with extremely odorous labels. To breeding season urine of tanooka males gets very proof and pungent smell which is gradually spreaded to many tens kilometers, and the marks left in winter continue intensive smelling even at the beginning of summer. Females find males using smell due to very keen sense of smell. Heat proceeds intensively at the female, and the female stays ready to pairing within several days in succession. It is enough to her to find a male ready to pairing. Heat at any individual tanooka female happens alternate years, at the end of winter.
Pregnancy lasts within about three months. The female gives rise up to five cubs, but usually it happens three or four of them. From the big litter only two cubs may survive to approach of independence, and per lean years only one may stay alive. To autumn young animals reach weight 90 – 100 kg. They will spend the first winter of their life with mother, and young females sometimes remain with her for the second winter and leave mother when new heat starts at her.
Life expectancy of giant tanooka is about 45 – 50 years.

At the Far East and in mountains of Central Asia this species is replaced by mountain tanooka (Tanuka monticola). It differs in smaller size (weight of adult individual does not exceed 350 kg), richer winter fur, which is colored lighter, rather then summer one, and annual breeding. This species is more herbivorous (the vegetative food makes up to 70% of a diet), and prefers small vertebrates, insects and carrion from food of animal origin. Mountain tanooka is more mobile, easily swarms up abrupt slopes and walks on narrow mountain tracks.

Shikala (Shikala strigicephalus)
Order: Carnivores (Carnivora)
Family: Raccoons (Procyonidae)

Habitat: tropical forests at the southern tip of North America.
By the end of Holocene, the number and diversity of American olingos – tree-climbing raccoons – had declined due to deforestation and hunting. However, they managed to survive in the remnants of the forests of South America and returned to the North America before the opening of Panama Strait. After the separation of the continents, in southern North America, a descendant of northern olingo (Bassaricyon gabbii) evolved, occupying the niche of primate – it is shikala. Unlike ozomatli, which lives in the forests of Florida and the Gulf of Mexico coast, this species has settled in the rainforests of Panamanian Peninsula.
Shikala is a small mammal: body length 36-38 cm, tail length 10-12 cm, and weight is up to 3 kg. Like its ancestor, shikala is a nocturnal animal (hence the name: Pitao-Shikala is the god of dreams among the Zapotecs), reducing in this way the competition with monkeys and other arboreal animals. Fur coloration is dim – chocolate-brown, lighter on the belly. Tail is decorated with snow-white and dark rings and serves as a means of communication. With its help, animals give each other visual signals, communicating with their family members and threatening strangers. Hands and feet have five digits equipped with hooked claws. It is an arboreal animal that almost never descends to the ground.
The eyes of this animal are large, round and looking like owl’s ones. They sparkle orange in the reflected moonlight. Animal also has wide rounded ears, further enhancing the resemblance to a lemur. In proportions and lifestyle, shikala resembles prosimians like potto – it is a stocky, slow-moving, nocturnal herbivorous creature. These animals live in groups: male, female and young of the last two litters, or groups of adolescents, within which new pairs form.
The basic food of these animals is fruits and oily seeds supplemented with leaves and flowers of trees. About a quarter of the diet by weight consists of invertebrates: insects, spiders and snails.
Breeding season is not pronounced, so both females ready to breed and mothers with two litters can be found in the forest. During courtship, the family male licks his female, but sometimes fights break out between them. The established couple declares their territorial claims, surveying the territory and leaving joint marks on branches and lianas. Occasionally, the partners arrange short scuffles, which subside very soon. Bachelors, on the other hand, chase females quite briskly, which is unexpected for this species, jumping along branches at a distance of 3-4 meters. If the female accepts the courtship, she stops, and after sniffing the applicant, she gibes chase to him – this is how the partners check each other’s health and strength. The duration of pregnancy is up to 100 days. The female gives birth to cubs – there are usually two of them in the litter. They immediately cling to the mother’s fur and travel on her – first on her stomach, then on the back. Initially, the cubs are taken care of exclusively by the mother; later the cubs of the previous brood join her. The cubs’ eyes open at the 5th day of life, but they leave their mother’s fur for the first time at about 2 weeks of age. They accustom to adult food at the age of about one and a half months, and after another 16 days the female is ready to mate again. At the same time, the previous brood leaves their parents, forming small clans of adolescents with their peers. Puberty begins at the age of 2; at this time, adolescent clans break up into breeding couples, and siblings always end up in different families. Life expectancy is 18-20 years.

Flag-tailed pampanasua (Pampanasua vexillicauda)
Order: Carnivors (Carnivora)
Family: Raccoons (Procyonidae)

Habitat: pampas of South America.

Picture by Timothy Donald Morris, colorization by Biolog

Initial picture by Timothy Donald Morris

In Neocene Atlantic Ocean had continued to extend, and, as if a wedge, had separated North and South Americas, having broken off isthmus of Panama. South America has moved little bit closer to South Pole, and it has resulted in expansion of temperate climate area and pampas – plain areas covered with grassy vegetation. In pampas herds of large animals wander – huge tapirotheriums, descendants of tapirs little bit similar to elephants, deermaras and giant paca – cursorial caviomorph rodents. They are pursued by hunting heron, large flightless bird, and also by acatou – the heaviest flying bird of the world. Among smaller animals inhabiting pampas, rodents, armadilloes (including rather large species) and numerous birds are characteristic. Among South American inhabitants of pampas monkeys are lack – not so numerous ground New World monkeys prefer to stay in woody regions and bushes. Original pampas analogue of baboons and other ground monkeys of Old World is the representative of raccoon family adapted to life in grassy plains – flag-tailed pampanasua. It is the descendant of one species of coatimundi (Nasua), successfully adapted to life in forestless areas after disappearance of significant part of South American forests as a result of human activity.
Compared to its ancestors, pampanasua has changed in significant degree. It is long-legged animal of gracile constitution about 60 cm high at a shoulder; body length of adult individual is up to 70 cm, not including tail. The body of pampanasua is covered with rusty-red wool with small dark spots on back and sides. Muzzle is long and has a mobile nose and well advanced olfactory chambers. Due to keen sense of smell pampanasua easily finds insect larvae and edible parts of plants under ground at the depth of about 20 cm.
Fingers of animal are short, but mobile, and claws are blunt: this animal swarms up trees worse, rather than its ancestor, and spends almost whole life in open areas where it moves on four paws more often. In order to look around pampanasua can rear on hind legs and keep vertical position within several minutes. For recognition of relatives this animal has contrast marks on muzzle: forward part of muzzle is white with black “glasses” around of eyes. The size of these “glasses” depends on testosterone content in blood, and at dominant males they are especially large. The size of marks allows quickly establishing of hierarchical relations, not resorting to combat. Males have long canines which tips stick out of the closed mouth. Defending itself from the enemy, pampanasua puts very painful bites.
Ears of pampanasua are long and have white hair brushes on tips. Auricles serve for removal of superfluous heat from organism.
Pampanasua lives the groups numbering up to 20 members – males and females of various ages. Animals communicate with each other with the help of various sounds – hissing, snorting, cooing and grunting. For communication with congeners at the long distance this species uses tail reaching 1 meter length. In the basis of tail pale cross-sriped pattern is visible, and on the tip the one-sided brush of lengthened hair of white color is developed; tail tip is black. In rest animal holds tail vertically and its movements are smooth. Quivering tail is the feature of alert animal. Usually animals signal this way to each other about snake found out. Pampanasua submits alarm signal in the voice – it is a series of abrupt shrill sounds similar to bark of small dog.
Usually pampanasua moves on the ground, but also can clamber on trees. The main enemies of these animals are hunting herons. Pampanasua hides from them, dropping to the ground and drawing tail in, or getting on trees. The group can frighten off a medium-sized single predator with menacing demonstrations.
Pampanasua is omnivorous and equally willingly eats food of vegetative and animal origin. Animals dig out tubers and bulbs, eat sapful bases of leaves of grasses, young shoots of bushes. Among food of animal origin pampanasua prefers insects, small reptiles and nestlings of ground birds. Frequently the group of pampanasua keeps near to large rodents and tapirotheres, and catch near them frightened insects and small reptiles. Due to keen sight and good hearing pampanasua right in time distinguishes approaching of enemies and warns large animals of their occurrence.
Twice per one year the female gives rise to one or two cubs. As this species leads migrating habit of life and does not build long-term shelters, the female must carry her posterity herself. The cub is born blind and covered with short wool. Right after birth it is able to cling to wool of mother and to twist her tail with its one. Due to it cub does not fall on the ground even if the female darts off sharply. Cub’s eyes open at week age, and at the age of one month young animals spend a significant part of time on the ground, getting on mother’s body only at the alarm signal. At one-year-old age young animal leads independent life. Males usually stay in parental clan, and females pass from one clan to another.
Sexual maturity comes at the age of two years, and life expectancy reaches 25 – 30 years.

Ozomatli (Procyolemur ozomatli)
Order: Carnivores (Carnivora)
Family: Raccoon lemuroids (Procyolemuridae)

Habitat: North America, evergreen deciduous woods at the coast of Gulf of Mexico and in Florida.
In Holocene representatives of primates order had gradually lost positions occupied in prehistoric time. Only one primate – man – had achieved fantastic power and prosperity at the expense of all ecosystem of planet. And only in some places unique species of small monkeys could coexist with people. Other primates became victims of hunting and human initiated change of natural environment. And once this vicious regime had failed: the mankind had disappeared, having fall a victim of natural laws which acted this species the same order as other ones. Stress, illnesses and adverse heredity had undermined reproduction of mankind as the species, and people had disappeared till some millenniums when some waves of global epidemics had swept across the world. Taken together with people, the part of primate species had died out: they are also subject to human illnesses. In addition the ice age rendered large influence to the number of primates, having reduced areas of suitable for them habitats. In Neocene when the situation had stabilized, some ecological niches earlier belonging to primates appeared occupied by absolutely other creatures.
One of such animals lives in woods along the coast of Gulf of Mexico. This creature resembles a little the monkey by shape, for what it has received the name “ozomatli” (in Aztec language it means “monkey”). Ozomatli dexterously swarms up trees, using paws with well advanced fingers. When ozomatli yawns, in its jaws six incisors instead of four ones characteristic for primates, are clearly visible. It unequivocally indicates the family tree of the present creature: ozomatli is predator very specialized to climbing habit of life, the descendant of animal cacomistle (Bassaricus astutus), belonging to raccoons family (Procyonidae).
Ozomatli is rather large creature: the adult male weights more than 20 kg, the female – about 15 kg. By separate features of appearance ozomatli resembles any monkey, but it has features, not characteristic for primates: on paws short, but sharp claws grow instead of nails. By proportions ozomatli resembles long-legged lemur: its head is rounded with large ears, body is lengthened, and mobile tail approximately one and half time exceeds the body length. Paws have sharp claws and well advanced fingers.
Rear legs are a little longer than front ones, due to what ozomatli can skip from branch to branch. At this animal feature of structure of extremities, more characteristic for primates, has developed: this animal does not cling to branches by claws, and clasps them by fingers and toes. To strengthen durability of clench, palms and feet of ozomatli are covered with wrinkled skin forming a semblance of papillar combs characteristic for primates.
At ozomatli there is short and rather wide muzzle: animal eats mainly vegetative food and small animals, and the part of molars had reduced. But force of bite has appreciably increased, that permits ozomatli to chew firm seeds and to crack nuts. Canines of this animal are also shorter in comparison with other predators.
Wool of ozomatli is short and rather thin: this creature prefers areas of warm and damp climate, not living in woodless areas. This animal has light brown colouring with thin cross black strips on back. Colouring of tail sharply contrasts to the body: it is light-yellow with black-and-white hairy brush of long hair on the tip. This hairy brush serves to the animal for communication with congeners: ozomatlies, as a rule, are silent, and only in case of danger they utter shrilly cry of alarm. Animals communicate with each other by means of tail movements. Thus the hairy brush is appreciable from apart, and permits animals to not give out themselves by cries.
Ears of ozomatli are rather wide, peaked and sticking in sides – they provide not only excellent hearing, but also protection from overheat in warm climate. Eyes of this animal are also big and shifted in forward part of scull. As the muzzle of animal is short, such position of eyes provides to it three-dimensional sight. Due to this feature ozomatli is able to jump in branches dexterously, covering the distance up to 5 – 6 meters and more. This animal is active in day time, as against to the nocturnal ancestor.
Ozomatli lives in deciduous woods at the southern coast of North America. It does not avoid swamp forests of Florida and Mexican coast, but does not live in woodless districts and light forests. This species is omnivorous and inclined to vegetarianism. The basic food of ozomatli includes fruits, seeds and nuts of various trees. Also this animal eats juicy stalks of orchids and other plants, and tree leaflets. It supplements the diet with invertebrates – snails, spiders and insects which this animal gathers in tree crones. Ozomatlies almost do not go down on the ground, preferring to travel in crones. These creatures keep in groups of several breeding pairs of approximately equal age, among which one pair has leading position. Pairs at ozomatli form to all life. Partners constantly care about each other, exchanging marks of attention: they clean each other, constantly keep beside and exchange by silent cooing sounds with each other.
Because this animal lives in districts where change of seasons is almost not expressed, animals having posterity may be met at any time of year. Two times per year the female brings posterity: one large cub covered with wool. The cub is born blind and with closed ears, and till first days of life it can only cling to mother’s wool. It holds for wool of female, and any time she holds the cub by one paw during jumps. At three-day age the cub starts to see and to hear, and its grasp becomes stronger. A week later it “settles” on mother’s back and starts to play with other cubs. Young ozomatlies keep near to parents almost before the birth of next cub: shortly before its birth female banishes grown up posterity, and young animals start to lead independent life. As a rule, they leave parental clan, joining other, small group, or form groups of same aged animals. Such groups differ in increased aggression, and can even supersede adult animals from rendered habitable territories. Ozomatli become adults approximately at the third year of life.
Life expectancy of this animal reaches 15 – 19 years.

Hopping carnocebus (Carnocebus saltator)
Order: Carnivores (Carnivora)
Family: South-American tail-grippers (Carnocebidae)

Habitat: tropical rainforests of South America, forest canopy.

Picture by Amplion, colorization by Lambert

Initial picture by Amplion

In glacial epoch rainforests of South America had seriously suffered from climatic changes. Because of dry and cooler climate of ice age their area had been strongly reduced, and they had remained only along the Atlantic coast of South America, and in lower reaches of rivers. Accordingly, the variety of local fauna and flora also had reduced. Especially large damage was incurred by groups of specialized wood animals among which only few species had remained. It had taken place with earlier numerous monkeys of New World.
In Neocene the climate became favorable for growth of rainforests again, but only few species of local monkeys had survived up to this time. In dense forest canopy they are compelled to compete to numerous animals of other groups adapted to tree-climbing and jumps.
One of such animals is very similar to Madagascar lemurs of Holocene epoch: it goes to feed at night, and hides in tree-trunk hollow in day time, covering by tail and paws large sensitive eyes. But it is not the primate, and a predator – carnocebus, the descendant of specialized tree-climbing raccoon kinkajou (Potos flavus). The name “carnocebus” emphasizes two features of this animal: the belonging to Carnivores order (Carnivora) and external similarity to South-American cebid monkeys (Cebidae).
Carnocebus inhabits tropical rainforests of the north of South America. This mammal keeps in forest canopy, practically never going down on the ground. Carnocebus is perfectly adapted to such way of life. It has fine inheritance from the ancestor – long tenacious tail which exceeds a little common length of body and head. The tip of tail is covered from below with hairless cornificate skin which makes grasp of branch stronger. When carnocebus climbs on branches, its tail, it seems, independently grasps the next branches, providing secure if the branch appears too thin. Paws of carnocebus are rather long because of what the animal is similar to monkey. Rear legs are a little bit longer than front legs because of what the back of animal is inclined forward. Due to strong rear legs carnocebus can make long jumps in forest canopy.
Fingers and toes of this animal are supplied with short, but strong and sharp claws. Till the climbing carnocebus simply clasps branches by fingers, but not clings to bark, as a cat. Thumbs on hand and foot can oppose to other fingers or toes.
Wool of carnocebus is short and velvety. General colouring of wool is brown; on back it is darker, than on paws and stomach. Eyes are bordered by thin ring of white wool; muzzle and area around of mouth are also white. The tip of tail is dark, almost black.
Carnocebus has inherited the habit of life of its ancestor: this is twilight and nocturnal animal. At it there are good hearing and very sharp sight. Ears of carnocebus are large, rounded, covered with wool on outer side, with fluffy fringe of long hairs on edge. Eyes of animal are big, round, directed forward: the muzzle of carnocebus is rather short, that strengthens its similarity to monkeys even more. Eyes of animal “shine” at night, as at cats: the retina has a layer of cells containing guanine which additionally reflects faint light rays to photosensitive layer of retina.
Carnocebus is omnivorous, but it obviously prefers food of animal origin. It eats insects and small vertebrates: mammals, frogs, lizards and sleeping birds. Carnocebus is so agile, that it can catch by jump even flying by birds and bats. The animal eats catch, holding it in forepaws, and sitting on branch vertically. In such moments animal additionally securing itself by tail clinging to the branch.
This is solitary animal spending day in shelter – usually in hollow of big tree. Less often carnocebus uses abandoned bird nest as shelter. When it is placed at top of tree, the animal arranges the original “canopy” of branches protecting from solar beams.
Carnocebuses meet and keep for some time in pairs only in breeding season. At this time the male some time cares at the female: cleans her fur and feeds her from the mouth. When animals sit on branch, the male can twist by tail the tail of the female. Animals spend day in common shelter, more often belonging to the female. When the female feels the approach of pregnancy, she starts to behave aggressively relatively to the male, and banishes him from the territory. Pregnancy lasts about three months, and on the average for two years at the female it happens three litters. It may be two cubs in litter. They are born rather advanced. Right after birth they can cling by paws to mother’s wool, additionally twisting her tail by their ones. They are colored darker than adult animals and have no white marks on muzzle. When the female moves in forest canopy, cubs sit on her hips and keep so strongly, that it can jump from tree to tree not being afraid for their life.
Young animals keep near to the female about four months. Usually at the end of this term the female again ready to pairing again, and cubs are banished by the male starting to court after her. Young carnocebuses spend first months of independent life together, and then each of them finds new territory to settle in. To this time animals become sexual mature. Duration of their life makes about 14 years.

Melikki (Martes nigripes)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: coniferous and mixed forests of Northern and Eastern Europe.

Picture by Alexander Smyslov

Mustelids survived the human era with fewer losses than cats and dogs. They were saved by the ability to feed on small rodents and the widespread distribution of many species. Among them, rare and narrow-range species disappeared during the human era, some other species did not survive the Ice Age, but the survived species took full advantage of the opportunities, giving rise to a number of specialized forms. Some species of the family have turned out to be relatively little changed – they belong to genera that existed in the human era. One of these species is melikki (the name means the Lady of the forest in Finnish mythology), a descendant of the European pine marten (Martes martes) of the human era.
It is a relatively small animal, with a body length of up to 40 cm and a tail of up to 25 cm. The color of its back is brown, with a grayish tinge in the south of the range; there is only occasionally a small grayish spot on the throat; legs and tail tip are black. Unlike its ancestor, melikki often hunts on the ground – this reduces competition with cat hermin, another arboreal mustelid species. Their ancestors once competed quite seriously for this niche, but cat hermin proved to be more successful, and superseded the martens to the northern regions, where they had to adapt to survive in the conditions of cold winters and the polar night. Only in the northern forests does this marten hunt in the treetops, especially in the krummholz areas. Melikki leads a mostly solitary lifestyle, guarding the borders of its territory and marking them with the secretions of the anal glands. This marten feeds on small ground-dwelling mammals, catches small birds and sometimes squirrels, as well as eats invertebrates and digs up bumblebee nests in search of larvae and honey.
Mating takes place in July. At this time, the males become aggressive and arrange fights for the right to mate with the female. On trees, they leave marks from urine and secretions of its anal glands, which the ready-to-mate female feels. Pregnancy is significantly prolonged due to diapause, and the offspring are born only in April of the next year. Female usually gives birth to three or four cubs, at first blind and covered with very short hair. They open eyes at the age of one month, and the two-month-old cubs begin to eat meat. A change in diet leads to an acceleration of development, and by autumn, young melikkis are completely independent. Puberty occurs in the second year of life, and life expectancy is up to 14 years.

Gliding weasel (Ventomustela zewanna)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: Balkan, woods to the north of the Alps; forest canopy.

Picture by Alexander Smyslov

In Neocene subtropical woods had returned to Europe. But trees forming them were not natives from the south. Mediterranean Sea, the shelter of thermophilic flora, had turned to heated salt desert, and the rich southern flora was lost, having replaced by drought-resistant plants of desert. Trees of European forests are descendants of species of flora of temperate latitudes: broad-leaved oaks and maples, relic plane trees, nut trees, beeches and chestnut trees. They had managed to survive in mountain valleys during the ice age, and after restoration of conditions favorable for life, had formed rich shady forests, stretched by strip from the Central Europe (to the north of the Alpes) through Tatra Mountains and Carpathian Mountains up to coast of Fourseas.
On the ground under forest canopy a few kinds of animals live, and the majority of inhabitants of European deciduous forests live in forest canopy. As against tropical rainforests, in European subtropical forests there are only few species of lianes, and crones of separate trees are not connected by them together. Therefore in canopy of European forests only ones live, able to fly well or … to make long gliding jumps. Abundance of prey had involved to forest canopy the predator perfectly adapted to movement in such inhabitancy. It is the representative of mustelid family, the gliding weasel.
The European gliding weasel has kept small size, characteristic for many mustelid species. The length of body of this animal is about 30 cm, and about 20 cm falls to fluffy tail. Between paws of gliding weasel skin membrane is advanced, permitting this little mammal to make long gliding jumps from tree to tree.
Head of animal is small and rounded, with short ears. Eyes are shifted to forward part of skull and provide good three-dimensional vision – it is vital for animal living in a forest canopy to estimate distance before a jump more precisely. The short wool of gliding weasel is colored brown, and on tail there are some black rings. The bottom part of body of gliding weasel is snow-white. To winter at individuals in northern part of area wool turns longer and a little lighter.
This animal is active and successful predator (it has received the specific name in honour of goddess of hunting of western Slavs). At gliding weasel there are large canines, and mouth can open very widely. Gliding weasel eats various forest rodents, bats and birds. This predator kills prey by bite in head. Gliding weasel often ravages bird nests, showing miracles of acrobatics and dexterously landing even on very thin twigs where the nest is built. This animal can climb in hollows to bee nests in searches of honey, and eats other insects and large spiders. Gliding weasel spends not whole life in tree crones. It often goes down on the ground in searches of forage. Being a predator by its nature, it does not disdain ripe berries, and in autumn cracks large oily seeds of beeches and chestnuts which grow in forests of Southern Europe much. On the ground this animal eats worms and insects. This mammal is able to climb on trees as dexterously, as squirrel, despite of presence of gliding membrane.
Gliding weasel is a solitary animal. Each individual has site in forest and marks it with odorous musky secretions. The territory of animal includes not only a part of crones of trees, but also trunks and the ground under trees.
Gliding weasel pair two times per year. First time courtship games occur at the end of winter when night frosts stop. Males start to come in territory of females and to leave their own odorous marks near female’s ones. If the female is ready to pairing, her musky secretions get a special smell well distinguishing by males. When the male feels it, he tries to reach the female as soon as possible. Sometimes at once some males follow one female. They constantly compete with each other, and sometimes can bite each other, putting deep painful wounds. Sometimes competing males seize each other’s gliding membrane, and one of them can pay for failure in courtship season by loss of ability to make gliding jumps. Eventually, near the female only one male stays, which pairs with her.
After the pairing the female banishes the male. Pregnancy lasts till about two months, and in second half of spring the female gives rise to 4 – 6 cubs. They are blind and helpless, and female looks after them within 2 months before they become independent. She hides cubs in deep hollow of tree at the big height. Young gliding weasels differ from adults in darker colouring of wool and absence of strips on tail.
Second time for a season the female is ready to pairing approximately in one month after cubs had ceased to suck milk. The first days of pregnancy the female concerns to grown up cubs tolerantly, but later starts to express aggression to them more often, and compels them to live independently. Second time it brings posterity at the end of summer. In the second litter it is less number of cubs – only two or three ones. But they are larger, than ones in first litter, and become quite independent predators to the beginning of winter.
The main enemy of these animals is large gospodar woodpecker which pecks out tree-trunk hollows and can eat newborn cubs of gliding weasel.

The idea about existence of this animal was proposed by Momus, the forum member.

Kama-itachi (Tardomustela nipponica)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: Japan Archipelago, Big Kurils, Sakhalin.

Picture by Alexander Smyslov

After the Holocene-Neocene extinction, the surviving mostly small animals received limitless opportunities for evolution. Mustelids turned out to be among those animals that realized them most fully. Some of them have become large animals, like berls, a genus of dominant terrestrial predators of Holarctic. And others gave rise to unusual local forms – like kama-itachi, that inhabits Japan Islands (in Japanese, a shapeshifter weasel with a sickle). This species is a descendant of Japanese weasel (Mustela itatsi).
It is a large animal: body length is up to 80 cm, tail is up to 70 cm, shoulder height is about 35 cm, and weight is up to 13 kg. In fact, it’s just a very large weasel – a predator that has retained its versatility despite its large size. Outwardly, this long-bodied beast resembles a fossa and a jaguarundi, although it has more pronounced mustelid features. Claws are partly retractable, and hind legs are slightly longer than the front ones; this species is a plantigrade animal. Summer fur coloration is brown with a white spot on the chest; winter coloration is lighter, yellowish-gray. Big Kurils and Sakhalin harbor local forms of this species, which differ from the nominal form in their dark summer coat color and smaller size.
Kama-itachi feeds mainly on small mammals, birds, reptiles and invertebrates. Unlike the heavier red-haired berl, it easily climbs trees, chasing squirrels and destroying bird nests. The only birds it avoids catching are the sumach finch, whose meat has an unpleasant taste, and the forest ronin. Kama-itachi also attacks Japanese harelopes and shishigami calves. Outside of the mating season, it is a solitary aggressive animal that expels rivals from its hunting territory.
The breeding takes place in February. At this time, males cross the borders of the territories of females in heat, chase them intensively through the branches of trees and on the ground, and use bites to force them to stop and mate with them. The strongest and most stubborn of the rivals fiercely fight over the females, which is why young males often get seriously injured and die. The male can mate with several females during the mating season, but stays with one of them and lives together in a den – a wide burrow with a nesting chamber at a depth of about 2 meters, dug in stony soil. Usually such burrows are made by females and serve as a shelter for several generations of these animals.
Cubs (3-4) are born after a three-month pregnancy well developed and covered with hair, and soon open their eyes. Immediately after the birth of the cubs, the female expels the male from the burrow and takes care of the offspring herself for the first weeks. Then, at first, the male begins to approach the brood no closer than two meters. Gradually, this distance is reduced and after a month and a half, the male is allowed to approach the cub closely. The cub begins to walk after 12 days, meat food appears in its diet after a month old age, and milk nutrition stops at 2 months. Being 2.5 months old, young kama-itachi begins to catch its first prey – insects and lizards. By the beginning of winter, the young animal appears completely independent, and the female expels it. By this time, the male usually already returns to his own territory.
Puberty occurs at the age of 3 years, and life expectancy is up to 20 years.

African paraskunk (Foetidictis major)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: North African savannas.
When major climatic changes began at the end of Holocene and the beginning of Neocene, the climate became much colder and more arid, and the tropical forest area narrowed even more compared to the human era. This circumstance opened up the possibility of faunal exchange between North and South Africa. Among the settlers, there was African polecat, or zorilla (Ictonyx striatus), the local equivalent of the skunk. In the human era, it successfully survived in a significant part of Africa outside the tropical forest zone, and in the early Neocene it gave rise to numerous new species, differing from each other mainly in size and preferred natural area.
After the end of the Ice Age, the African tropical forest zone returned to its former borders, and after the opening of the Tanganyika Strait, the forests divided this continent almost in two halves. The various descendants of African polecat appeared in isolation, and their evolution continued independently; some of them became extinct, but others continued to exist and evolve. African paraskunk is one of these species.
It is a fairly large animal by mustelid standards: about a meter in length, and 30-50 cm in height at the shoulders (the male is larger). Broad stripes of light wool of the ancestral species have almost merged together on the back and on the long bushy tail (only a narrow intermittent black stripe remains between them), while the sides and belly are much darker. The silver-gray coloration of the upper body allows the paraskunk to avoid overheat under the sultry African sun. When an animal sleeps curled up in a ball, it hides its vulnerable head under its tail, protecting it from the heat of the sun. The body hair is quite coarse and tough.
Enemies of paraskunk are not numerous: this beast has not only a vicious and quarrelsome temper, sharp teeth and claws, but also smelly, poorly flushed secretions. When an animal is attacked (or it just seems to it – it has poor eyesight, although its sense of smell and hearing are very well developed), it turns its back to the aggressor and shoots a white, greasy, odorous and pungent secretions at it. As a rule, this is enough, and the enemy flees – the secretions quickly thicken in the air, and it is very difficult to scrape them off wool or feathers, and the unpleasant odor irritates the sense of smell of predatory beasts for a long time. But still, some African predators like the panther genet are capable of killing and eating this animal.
Paraskunk itself hunts various insects, amphibians, reptiles and small birds, eats a large amount of plant food, as well as carrion. This species lives in pairs – this animal is less unsociable than many other mustelids. The mating season begins during the rainy season. At this time, single paraskunk males search for females by scent, and if several males meet together near the same female, a fight begins between them, in which the winner is determined. Family males often receive challenges from singles, so they are forced to defend the right to a female and territory. The female, as a rule, protects the territory from the stranger together with her male, and they expel the strangers together.
Pregnancy lasts about six months, after which the female gives birth to 1-2 cubs. They are blind and helpless at birth, and the female guards them by hiding them in a den, while the male hunts and provides them with food. The cubs grow quickly, and at the age of 7-8 months they are already independent. Shortly before the mating season, they leave their parents forever and lead an independent life. They reach sexual maturity by the age of 3 years. The maximum life expectancy of paraskunk is about 25 years, but usually much shorter.

Antipod’s unotter (Xenolutra antipodorum)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: New Zealand, sea coast and lower stream of rivers.

Picture by Pavel Volkov

Freshwater ecosystems of New Zealand had been remarkable in poverty and high degree of endemism in comparison with continental ones. It is connected with very early isolation of archipelago, which had taken place before occurrence of the most typical families of freshwater fishes and other water vertebrates. The situation had sharply changed in human epoch when various species of freshwater fishes and predatory mammals had been introduced to islands. After disappearance of mankind their descendants had changed freshwater ecosystems up to unrecognizability. One of such species lives in lower reaches of rivers of New Zealand; it is a predatory aquatic mammal, crowning with itself the food pyramid of ecosystem. By shape this animal is very similar to otter, but is connected to it with only remote relationship by origin: it is the descendant of the domesticated American mink (Mustela vison) introduced to islands in human epoch. This animal is named antipod’s unotter. It is much larger, than the ancestor: up to one and half meters long including wide flattened tail.
At antipod’s unotter there are rather short paws with long fingers connected by elastic membrane. The antipod’s unotter is very vulnerable on land, but in water only few animals can make a competition to it. For slow and maneuverable swimming animal uses paws, but at hunting in open water unotter presses paws to body and swims with the help of vertical bends of backbone and movements of tail. Tail of antipod’s unotter is wide and flat, similar to beaver’s one. It is covered with dense skin and shorter fur, than the body.
Antipod’s unotter has flattened head with short strong jaws which easily crack skull of fish up to 40 – 50 cm long, or the armour of large crab. Ears of animal are short and rounded. On muzzle of unotter long rigid whiskers – vibrisses – grow; with their help animal searches for prey under water.
The body of unotter is covered with dense rich fur of grey color with white spot on throat which passes to longitudinal strip on stomach. Fur of antipod’s unotter is rich and dense. It reliably keeps air, and consequently animal is not cold even in cool water. Unotter carefully looks after fur, and combs it with two wide claws of forepaws which bottom surface forms “combs”. The animal also greases fur with secretions of former musky glands, located near the anal aperture. In this connection they had strongly changed: having lost smell component (the strong smell is characteristic for many mustelids), they became plentiful and oily. Cubs at which glands poorly function yet, use for care of fur secretions of the female.
Antipod’s unotter is active piscivorous predator. It usually hunts in coastal zone and in thickets of brown algae. These animals especially willingly catch pelagic fishes which shoals swim up close to the coast. The group of animals attacks fishes, and drive their shoal into algae thickets where fishes lose orientation: in such situation it is easier to catch them. Besides of fish, antipod’s unotter eats crustaceans and small snails. After storm these animals gather on coast dead sea animals cast ashore.
By the way of life the antipod’s unotter is social species. It settles at sea coast or in mouth of the river in big groups numbering up to ten breeding pairs of adult animals. Besides of them in groups there are some single adult individuals, and also numerous youngsters – the posterity, yet not completely passed to independent life. The colony lodges in places where there is an opportunity to arrange shelter. Animals dig in the ground some common holes, or lodge in cave well protected from storm waves.
The pair at antipod’s unotters is formed to all further life. Partners differ in attachment to each other – they have a rest and hunt together. Male is larger, than female and female regularly renders to him signs of attention and submission – she clears and greases his fur and licks his muzzle. Once a year, in early spring the female gives rise to 3 – 5 cubs. They are born blind and deaf, but covered with wool. The female gives rise to posterity in shelter, on litter of grass and seaweed. First some days she does not admit to posterity even her male. Week-aged cubs start to hear, little bit later eyes open at them. At the age of 17 days cubs start to creep out from den and to explore the world around. The female feeds them with milk approximately up to bi-monthly age, but already fortnight cubs start to try food of adult animals: male brings in the den fish, and the female allows cubs to eat a little. At the age of two months young animals already leave a den and start to study to swim and to get food independently.
As a rule, males abandon the group at the age of half-year. They lead barchelor life, and can found their own colony if they find a place suitable to life. If the parental colony is overpopulated, adult individuals can show aggression to young growth. Then even young females leave a colony; later they can join a colony of bachelor males and form breeding pairs with them. At the age of two years young animals become able to breeding.

Littoral mink (Neovison dicynodonta)
Order: Carnivors (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: sea coasts of North America from polar to temperate waters.
Among mammals the mustelid family shows rather different shape of species included, varying from tiny weasel conceding to some rats in length, up to glutton close to bear cub in size. Mustelids live on trees (marten, American mink, etc.), under ground (badger, black-footed ferret etc.), and even in water (otters and minks). In Holocene separate representatives of this family even devepoled oceanic habitat! Also it is necessary to note that seals descend from early mustelids.
Short, but severe epoch of anthropogenous pressure and climatic changes took place right after it had been a true test for durability for mustelids. The area of some species had been reduced, and some of them had become extincy completely.
In due course mustelids began to return former positions and to occupy again ecological niches lost earlier. American mink (Neovison vison) had occupied a niche of otters extinct on human fault, and in due course was settled up to ocean. It had not become high-grade analogue of sea otter (Enhydra lutris) dyed out at the boundary of Holocene and Neocene, but evolved to one of the most unusual mustelid representatives of Neocene – littoral mink.
Littoral mink is an animal kept features of the ancestor in many respects: lengthened body and tail, and short webby paws. But it is also adapted to new inhabitancy and had developed special attributes, not characteristic for ancestor. One of the main features of this species is the structure of teeth. Incisors are still sharp, but strongly reduced. As opposed to them molars are low, but wide and massive, with the powerful roots, resembling nutcrackers. Canines, though they stick out of mouth, as if “sabers” of other predators, are absolutely straight and smooth, resembling tusks of Holocene walrus. Littoral mink is its ecological analogue, though in miniature.
This animal has rich fur of brown color. Littoral mink carefully looks after it, cleaning the dirt with claws of forepaws and greasing it with fat musky secretions of anal glands.
Bones of mink skeleton turned appreciablly heavier, and muscles have become stronger: it is twice longer than its ancestor and almost ten times heavier. It allows an animal to dive under water and to remain there till 15 – 20 minutes without any serious problems. Certainly, it is not enough to catch quickly swimming pelagic fishes and squids, but this mink does not hunt them: its prey includes bentic fishes and crustaceans, bivalves and gastropods, less often sea urchins and starfishes. It easily cracks shells and carapaces of animals by molars, and tears off snails and bivalve shells from stones by canines.
As well as other sea mammals, mink swims, waving by the whole body in vertical plane, and uses short and wide hind feet and extended tail as rudders. Forepaws also have palamas between fingers, but do not take part in underwater movement: sea minks use them for movement overland where they move in seal manners – on all fours, pushing by hind legs.
The main enemies of littoral mink are predatory fishes and orcine squids. On land it is attacked by coastal predatory birds and carnivorous mammals searching for food in coastal zone. But ground predators are usually dangerous only for cubs: adult minks, having powerful jaw bones and muscles, can be formidable opponents. Protecting themselves, they put deep bites. Pain sensitivity is reduced at them, therefore littoral mink, protecting itself from large predator, can hang on it in death grip and does not unclench jaws even if it will be gnawed and biten.
Littoral minks live at both coasts of North America. The Pacific population is isolated from Atlantic one by Beringean Isthmus at the north and by tropical areas at the south. Probably, it is formed as a result of unitary settling of the Atlantic population to the south during any short-term ice age. To winter animals of northern populations swim to the south: despite of rich fur and underskin fat, these animals bear cold Canadian winters not so successfully. They migrate in large packs, pursued by sea predators hunting weakened and left behind animals. In spring migration takes place in opposite direction.
These animals keep in family groups including 1 – 2 males and 4 – 6 females. Females of littoral minks bring posterity in second half of spring, after the arrival to summer residence. In litter it may be up to 7 – 10 cubs, but within the first year of life less then half of them will survive – the others perish from predators or during autumn migration.
The maximal life expectancy of littoral minks is 12 – 15 years.

Kushtaca (Kushtaca pacifica)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: Pacific coast of North America from Beringia to temperate regions.
Biospheric changes at the end of Holocene and the Ice Age that followed caused serious damage to otters, whose population in the human era was undermined by hunting and overfishing, depriving them of food resources. Other mustelids and even rodents (dormice) have taken the place of otters in continental ecosystems, and the aquatic descendant of the star-nosed mole lives in Mishe-Nama lake. In North America, the semi-aquatic American mink (Neovison vison) of the human epoch evolved into an ecological analogue of otters, and two of its populations in Early Neocene managed to adapt to catching marine fish. And if the Atlantic population died out, unable to compete with gannetwhales, then the Pacific descendant of the mink thrives on islands off the coast of the continent, giving rise to a new species, kushtaca.
Compared to its ancestor, this beast has become very large: its body length is up to 1.7 m along with its tail, and its weight is about 50 kg. The animal’s physique is slender, its spine is flexible, and the tail is wide and paddle-shaped. Fur is thick and dense, gray in color with a white spot stretched from the throat to the upper belly. Head is relatively small, with shortened muzzle, large eyes and reduced ears, which look as small skin folds that serve to close the auditory canal. Vibrissae are well developed on the sides of the muzzle and above the eyes. Neck is elongated and flexible: the animal is able to turn its head almost 180 degrees. Teeth are pointed, with developed cutting edges.
Paws are short and thick, and digits are flattened and completely fused – they resemble flippers, although they are still suitable for walking on land. Claws adapted for grooming and climbing wet rocks grow on the front paws. Hind legs are long-toed and have reduced claws. The beast swims with the help of undulating bends of the spine, making a stroke simultaneously with its tail and hind legs. Slow swimming is carried out by rowing with the limbs alternately.
Kushtaca lives on the ocean coast in family groups – male, female and their current year’s offspring. Each group owns a certain section of the coast. Congeners are not allowed to the group’s resting place closer than 10-15 meters, except during the wintering period, when the animals are more tolerant of their congeners. But violent fights between them are rare: usually the conflict takes the form of a displaying of an arched body on straight legs, which is accompanied by hits and growls. Bloody fights occur only during periods of lack of food, or when certain areas of the coast are overpopulated.
Kushtaca feeds on fish that it catches in the water column at a depth of up to 10 meters away from the shore. This reduces competition with its usual neighbor, the imperial murre. Other fish-eating birds rarely dive to this depth. Occasionally, this species catches crabs in coastal shallow waters, and even on the shore. Kushtaca easily swallows small fish underwater, and eats larger ones like its ancestor – having emerged and holding them with its front paws. At this time, the animal resembles a grotesque human figure in the waves, which determined the name of the species (the name means shapeshifting otter in Tlingit). These animals winter in warm southern waters: they migrate south in September and October, visiting California island and reaching the coast of Panama Strait. At this time, the breeding pairs break up.
Mating in animals takes place in the summer, when the female’s body recovers after the birth of offspring, and there is enough food in the ocean. Males and females chase each other in the water, assessing the physical condition of their partner. There is an active competition between the males, accompanied by ritual tournaments, occasionally turning into a fight. Mating takes place in shallow water, with the male holding the female by the scruff of the neck with his teeth. Pairs are formed for one season, and sometimes a male can fertilize two or three females. Due to the latent stage, pregnancy lasts 10 months; the birth of offspring takes place at the end of April-May, when the animals return from their wintering areas and recover after migration. The delivery takes place on the shore, the female usually gives birth to two cubs; single cub in litter is rarity. Young animals are born well-developed, with their eyes open, but they cannot swim. They feed on mother’s milk for 2 weeks, and then they start eating fish caught by their parents and learn to swim in coastal waters. They stay with their mothers until the beginning of the autumn migration and learn to hunt fish and interact with their relatives. At one year of age, the young are completely independent, and at the age of 3, the animals are ready to breed. Young males start mating only at the age of 5, having gained strength and experience in fighting and courtship. Life expectancy is up to 30 years.

Grokk (Quasiursus grokk)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: Western, Central and Southern Europe, Atlas Mountains, Asia Minor, the Caucasus peninsula.
During the first millions of years of early Neocene world resembled a little the early Palaeocene, as small animals quickly increased in size to occupy the vacant niches in emerging ecosystems. The ecological niche of bears at the area of Holarctic had been taken over by the large descendants of ferrets (Mustela putoris) that form a single berl (Quasiursus) genus. Only in the Far East they are replaced by two more predators: arctomeles (Arctomeles tardus) and giant tanooka (Tanuka gigantea), natives of Oriental zoogeographical realm. South of the Alps, Western Europe and North Africa are inhabited by grokk, another representative of berl genus. It evolved in relative isolation from another species and is slightly different from them. This is a predator and a scavenger, an ecological equivalent of the Holocene bear, but more carnivorous: plant food makes not more than 10% of the diet.
The grokk is reminiscent in appearance of a cross between a ferret and a badger, but is an animal of a large bear size; its shoulder height is about 1 meter. It has an elongated body, pretty short strong paws, large head and short tail. The fur of the grokk has sandy-yellow shade with darker legs and a “mask” on the muzzle. Tail is also dark, but with a white tip. Grokk is a sluggish animal with plantigrade feet, but over short distances, it can run at a very high speed, catching up with its prey. This animal’s claws are long and non-retractable.
This mammal is a carnivore, it has strong jaws, and molars have a well-developed cutting edge; the canines are elongated. Grokk’s sense of smell is very acute – the nasal cavity is quite extensive, and due to it animal’s head is shaped more like a cat’s than a bear’s. The eyesight is comparatively weak, the eyes are small. Hearing is sharp – the external ears are moveable and are located at the top of the head.
The grokk is a solitary predator, specializing in hunting for large herbivores – tapiroids and embolohyraxes. This species has tremendous strength, and the adult animal is capable of toppling a young embolohyrax on the ground and breaking its neck. Also, this mammal willingly eats carrion, finding it by smell. Using its superior strength, this species easily seizes prey from other predators. In the Atlas Mountains, this mammal attacks young giraffe ostriches. Due to this feeding specialization the population of the predator is widely dispersed. Each female occupies approximately 100 square kilometres of territory and in fact spends its whole life there. On contrary, the males travel much more: they roam vast territories, partly overlapping those of other individuals. The territory of each male includes territories of several females. During the mating season the male indulges in long wanderings, fertilizing females that live within its posessions. Each individual marks its territory by using secretions of musk glands, inherited from mustelid ancestors, and communication of different individuals occurs mainly through scent marks that these animals leave on the noticeable elements of the landscape – on large stones and single trees.
Grokk is a quiet animal. Using sounds in communication occurs mostly between females and their offsprings, and when meeting each other, two adult grokks roar loudly, trying to oust a rival from its territory. The voice of the grokk in calm is a short snarl, hence the onomatopoeic name of the animal.
The mating season begins in the fall. When ready to mate, the female produces a distinctive odor, which attracts males. After the end of estrus the female chases away the male. 2-3 cubs are born in spring, within the first few weeks of life intense competition arises between them, and fights take place often. Only one cub of the litter usually reaches the independent condition. The sexual maturity comes at the age of 3 years; the life expectancy is up to 50 years

Aotearoan False Glutton (Pseudogulo australis)
Order: Carnivores (Carnivora)
Family: Weasels (Mustelidae)

Habitat: Well vegetated habitats across New Zealand, with a preference for those that are not swampy, including mountain slopes, woodlands, meadows, savannah and coasts.

Picture by Alexander Smyslov

The introduction of ermine and ferrets to New Zealand by mankind during the Holocene was a catastrophe for many kinds of native animal there, particularly ground-nesting birds. But these animals were provided later opportunities to prosper in the Neocene, radiating into new niches, omnivores, burrowers, and scavengers.
One notable scavenging form is the Aotearoan False Glutton, this is a large, bulky Mustelid descended from the ferret, recalling a wolverine in shape. Body length is up to a 85 centimeters, and weight in large individuals can be up to 25 kilograms. Animal is built low to the ground with strong, powerfully built limbs, tail is short and bushy. Head and jaws are massive, cutting teeth are large and accompanied by heavy crested back molars for processing bone, canines are long. Colour recalls partway between ferret and wolverine, with a dark back and limbs, lighter sides and a dark “mask” around the eyes.
Diet consists partly of mid-sized and small animals caught for itself, rabbits, birds, large rodents and snakes, but a great deal of its diet comes from scavenging carcasses left behind by other predators, Kurī hou, Ruacapangi bird or Marsupial Pardus. In this way it recalls a miniature hyena, as it is able to gnaw and crush bones as well as consuming flesh and organs. Sometimes as many as four or five may congregate around a carcass, and only the larger bones and ends of some bones usually remain, some may be cached to eat later. This animal is active the most in the late afternoon and early morning, including twilight. Calls vary from a chirring growl to a yarring squeal. Males produce an extremely strong glandular odour, and mark their territory with glandular secretions, but it does not use glands in defence as a skunk would.
Though generally solitary and quarrelsome amongst themselves, dominant males will allow multiple females within their home territory, mating with each of them and preventing mating by smaller males. Breeding season is in winter from June to September. Gestation is up to 35 days with litters of two or three young born in late spring, weaning at 10 weeks, cubs reach adult size within a year and are overall darker than their parents. Lifespan may be up to 14 years.

Black jaguape (Manducomellifer niger)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: South America, tropical forested areas.

Picture by Pavel Volkov

The introduction of species to new areas by people during the Holocene epoch caused many impacts over the indigenous species of these habitats. Some species were capable to adapt to the presence of the invasive ones, and even to develop ecological relations with them. The mammalian genus Manducomellifer appeared in this context, descending from the tayra (Eira barbara). These mammals are adapted to eat honey, larvae and pupae of bees, mainly of those belonging to the genus Apis introduced to South America during the Holocene. The type species of this genus is black jaguape (the Tupi word jaguape is used to refer to the tayra). This animal lives in the tropical areas of South America.
Black jaguape is 65 cm long with 40 cm long tail; female is smaller than male. These animals have short black fur on the body, limbs and tail, with two yellow stripes coming from their snout, passing around the eyes, to the back. These stripes represent a feature common to all species of Manducomellifer genus. Their appearance resembles that of a slender badger; this mammal has slender body with short ears, small eyes and short snout. This species has skin so thick, that bee stings rarely penetrate it. They have long claws on the forepaws, which they use to excavate hives in the ground or in hollowed trees. Black jaguapes are good in tree climbing, being capable to leap from treetop to treetop when pursued, using their tails for balance. Mostly diurnal, they sleep in hollow trees or burrows at night.
They are opportunistic omnivores, hunting rodents and other small mammals, as well as birds, lizards and invertebrates, and climbing trees to get fruits. However they have a great appreciation for honey, larvae and pupae of bees – these are the most common elements in their diet. When black jaguapes find an underground bee colony, they dig it and not suffer too much from bee stings, due to their thick skin. All jaguape species developed an ecological relationship with bee-eater tanager, bird of the subfamily Apiphagiinae in Thraupidae family. When jaguape appears near them, these birds perch on tree near bee nest and start to vocalize. It attracts the attention of the mammal to bee colony, and when the mustelid begins to ravage the nest, bees try to defend it. As the jaguape begins to devour honey and larvae, the birds begin attacking and hunting bees defending the colony.
Black jaguapes breed year-round, with the females entering estrus several times per year for 15 days at a time. The territory of a successful male overlaps that of two to five females. The female gives birth to one to three young and takes care to them for alone. Newborn cubs are blind and have closed ears, but are already covered in a full coat of black fur. Their eyes open at 46 days, and they leave the den shortly thereafter. They begin to take solid food around 70 days of age, and are fully weaned by 105 days. Hunting behavior begins as early as at three months, and the mother initially brings to her young any wounded or slow prey to practice on as they improve their killing technique. The female also teaches them to hear and to follow the vocalization of bee-eater tanagers to find bees. The young animals are fully grown being around 6 months old, and leave their mother to establish their own territory in 10 months. The lifespan of this species is about 15 years.
There is another species in the genus Manducomellifer – Andean jaguape (Manducomellifer andinus). Living in elevated areas of the Andes, this species has 50 cm of length, with 29 cm long tail. Its fur is longer and has light brown shade. These animals have the same yellow stripes as previous species, but their coloration is duller. Andean jaguape is also less agile in trees and climbs rarely. In southern part of South America it lives not only in mountains, but also in southern temperate forests, forming a separate subspecies M. a. australis that is 67 cm long with 33 cm long tail. Its fur turns longer in winter and is dark brown, and stripes on head are yellowish-orange. When bees gather in their nests to spend the winter, austral jaguape passes to a more carnivorous diet.

Gurahl (Spectreira lycoides)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: South American jungle.
After a profound ecological crisis caused by human activity, tropical forests broke up into fragments of relict selva surrounded by secondary dry forests and pampas. Many large animals, including jaguars and bears, disappeared along with the jungle. But the tayra, like most mustelids, survived, and its descendants spread wider and even passed to a larger size class. Jagueira lives in Patagonia, and its relative, gurahl (the name means a shapeshifter bear) of smaller size, is found in the warmer jungle.
In its physique, gurahl resembles a small, slender bear. Body length is about 1 meter, the tail is 30 cm, the height at the withers is 60 cm; limbs are plantigrade. The weight of an adult is 45 kg. Wool is dark brown, with light spots around the eyes and on the forehead. Muzzle is short and wide, with cutting teeth. Ears are short and rounded. The beast has keen hearing and sense of smell.
Gurahl is a crepuscular animal; peak of activity is 2 times a day – at dusk and shortly before dawn. It hunts a wide variety of small animals – rodents, birds, reptiles (including turtles and young aquaguanas), medium-sized primates, ungulate cubs and caviomorph rodents.
Gurahl hunts both on the ground and on the lower branches of trees. It most often searches for food in trees when rivers flood. Since this animal feeds on a more diverse prey than ipochereu, and rarely climbs into the crowns of tall trees, these two species compete to a lesser extent. Gurahl is a territorial animal; an adult beast marks the boundaries with secretions of its anal glands.
Seasonality in reproduction is not pronounced. 3-4 males can gather on the territory of the estrous female; they growl at each other and sometimes fight, wrapping their paws around the opponent and trying to knock him down. After such fights, the shoulders and sides of males may be scratched to blood by the claws of rivals.
After 3 months of pregnancy, the female gives birth to 2-3 cubs, which she hides in a shelter – usually in a large tree hollow or in burrows. They open eyes at 5 weeks, and from the age of 40 days they taste the meat – first regurgitated by the mother, then they begin to tear apart the prey brought by the mother on their own. At the age of 10 months, they become independent, and the female is ready to mate again. They become sexually mature at the age of 3 years, and have a life expectancy of about 22 years.

Dorgon, or Anteater badger (Myrmeles insectophagus)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: forests of southern Siberia from Ural Mountains to the Far East.

Picture by Chmumrikk

In Neocene, there are various animal analogues of Holocene anteaters on different continents. They are more typical of the tropics, where they thrive in a stable climate and an abundance of insects, achieving a high degree of adaptation to such a lifestyle. In the course of convergent evolution, the same kind of animal appeared in the forests of Southern Siberia from Ural Mountains to the Far East. It is anteater badger, or dorgon (“badger” in Buryat).
Dorgon searches for food, mainly by tearing up huge anthills of forest ants. It also forages by breaking stumps and fallen rotten trees with its powerful paws with sharp claws, or climbs on decaying trees standing alone, intentionally breaking off the bark and eating all the small animals living under it: woodlice, millipedes, earwigs, bark beetles and their larvae, etc. The beast can also ravage the nests of wasps, bees and bumblebees, feeding not only on the insects themselves, but also chewing combs along with larvae and honey. After the rains, the beast digs up the wet ground in search of earthworms and can also eat slugs and small snails along with the shell, as well as small berries. Dorgon can feed on bird eggs, cracking them with its claws and licking the liquid from eggshell with its tongue.
Anatomy and physiology of this animal fully correspond to its type of diet: muzzle is long (longer than that of the Holocene coati, but shorter than that of the anteater), tongue is long and sticky, one and a half times longer than the muzzle. In the mouth, salivary glands are well developed, secreting sticky saliva that thickens in the air. Teeth are small and pointed; molars equipped with several cusps are of a piercing-cutting type, adapted for feeding on small prey.
Wool of dorgon is short, thick, stiff and bristly – it protects the beast from insect stings. On the nose, which is most often attacked by insects, there is a small area of corneous “armor”. The coloration of the animal is contrasting, black and white: the lower part of the head, cheeks, throat and chest are white; there are white “socks” on the paws; tail is covered with long white hair, and there is a white spot on the rump at the base of the tail.
The animal has significant immunity to insect venom, and even snake bites are easier for it to withstand than to other mammals of similar size. This species is short-sighted, but it perfectly distinguishes the movement of insects in its immediate vicinity. It has a very keen sense of smell and hearing. The sensitive ears of this badger face slightly forward and down; thanks to its acute hearing, anteater badger can easily spot insects even in the dark. But at night it hunts insects only if it gets very hungry. Unlike its badger ancestor, it is a fully diurnal animal.
Because of its large claws, this animal has developed a gait like an anteater: it walks leaning on the back of its hand (here “calluses” of thick, thick skin are developed), with its claws bent inwards. Dorgon is not afraid of predators at all: even large predators that are found within its range – berl, tanooka, menkw and Siberian sabretooth – prefer not to mess with it. In the case of a predator attack, dorgon shows aggression and goes on the attack, purring loudly and trying to inflict as painful wounds as possible on the attacker, aiming its sharp claws primarily at the opponent’s muzzle. If a predator attacks from behind, dorgon sprays into it a pungent, smelly liquid secreted by anal glands. The jet of liquid sprays up to 2 meters away and temporarily prevents the predator from smelling odors.
It is a beast up to 110-130 cm long. The weight of an adult is up to 40 kg, but over the summer the animals eat up to 60 kg. Males are slightly larger than females. The beast is solitary; it lives in burrows and protects a fairly extensive feeding area, the boundaries of which are marked with scent tags.
These animals gather in groups only at the end of summer, when the females begin to heat. Then several males begin to compete for the attention of the females. Males display their giant claws to each other, growl and try to push the opponent away from the female by side. If males of approximately equal strength meet, they begin a fierce battle with their claws, inflicting wounds on each other’s skin. But such a battle lasts no more than five minutes, and the defeated dorgon simply runs away from the battlefield, licking its wounds. These animals have a well-developed ability to regeneration – they are able to survive even after being in the claws of a predator and losing large patches of skin.
Having accumulated fat for the winter, dorgon hibernates, hiding in a deep, pre-dug wintering hole. It runs into hibernation very early in autumn, with the first touches of frost, and leaves the burrow only after the snow melts. The animal falls into a true hibernation, when the processes of vital activity slow down greatly, and the body temperature drops.
Pregnancy with diapause actually lasts about three months. In spring, the female brings two or three small blind and deaf cubs. Cub has a short muzzle, which makes it easy for it to suck mother’s milk. Cubs open eyes at the age of 2 weeks; at the age of one month they already leave the burrow and learn to forage, and at the age of three months they already feed themselves. In autumn, on the eve of hibernation, young animals dig their own “bedroom” in the mother’s wintering hole and spend the winter in the same hole with the female. The families break up in the spring.
Females become sexually mature in the second year of life, and males – a year later. The life span of dorgon is up to 12 years, large males live up to 15-16 years.

Akashita (Akadzitus japonicus)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: Japan Islands, forests in mountains and valleys.
Widespread, omnivorous, and evolutionarily flexible, the badgers of Eurasia survived the human era with minimal losses. Only the Japanese badger became extinct, unable to withstand the extermination and deforestation. However, during the Ice Age, when Japan Islands were connected to the continent, badgers from Asia entered there. Competition with other predators in conditions of island isolation forced them to evolve towards relative herbivory. This is how akashita appeared on the archipelago, a kind of panda analogue among the mustelids.
It is a relatively small animal with a stout build: body length is up to 70 cm, height at the withers is about 35 cm. The tail is almost absent. Muzzle is shortened, wide, equipped with strong chewing muscles and cuspidate molars, the canines are shortened. Wool coloration is dark brown with white and red stripes on the muzzle, which form a pattern resembling an open beast’s mouth. Two large strokes stretch across the eyes, visually exaggerating them. Limbs are plantigrade, short and capable of digging. Animal has powerful front paws with large claws. Hence the name of this species: Akashita is a black spirit with large claws and open mouth.
Akashita feeds mainly on the underground parts of plants – roots, tubers and bulbs, and also willingly eats mushrooms, including slightly poisonous ones. Beast eats with pleasure the dug out animals, both invertebrates and small vertebrates. These animals eat eggs of birds nesting on the ground, broods of rodents, and do not disdain carrion. In the north of the archipelago, where snow falls, akashita attacks small forest harelopes or follows large predators and picks up the remains of their prey. In mountainous areas in the cold weather, the animal becomes sleepy and may not leave its shelter for several days in a row. In the south of its range, the animal stays active all year round and does not stock fat.
The animal spends the night in a deep burrow with several additional exits, which are usually covered with earth. Often, one individual digs several burrows, which it uses when moving around its feeding area, spending the night in each of them for several days. Akashita is a solitary animal that does not tolerate animals of its own kind and expels them from its territory; only the female and her cubs keep together until they become independent. This animal defends itself from predators by spraying a musky-scented jet onto the ground, or by trying to hit the attacker with its claws.
The mating season starts in May and lasts until the beginning of June. At this time, males search for females by smell – their secretions get a specific odor during estrus. Several males can gather on the territory of one female, competing with each other for the right to mate. The opponents growl, bristle their fur and bite during their fight, but do not use their claws. Often, the dominant male drives off its rivals simply by smell of its musky secretions. After mating, the winner keeps near the female and drives the rivals away from her for a while. When the female’s heat period ends, she drives the male away on her own.
Usually, shortly after mating, the development of the embryo slows down until winter. At this time, the female accumulates fat, which is used during the winter, including for the development of embryos. Two cubs are born in March or April. They are covered with hair at birth, but their eyes and ears are closed and open only in the 2nd week of life. Then the cubs develop quite fast. At the age of 1.5 months, they gradually begin to taste adult food and accompany their mother in the forest, and at 5 months, young akashitas are completely independent and begin to eat off for the upcoming winter. Puberty occurs at the age of 2 years, and life expectancy is up to 19 years. The adult animal’s enemies are large cats and owls, and the cubs are attacked by large mustelids. Through the eaten insects, the animal receives a large number of helminthes.

Niagwahe (Taxideima gigantea)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: prairies and woodlands of North America.
North America is a continent that had regularly connected to Asia for more or less a long time. Depending on this, faunal exchange took place between the Old and New Worlds, or evolution passed independently and in North America its own endemic groups of animals evolved, that regularly passed the viability test, mixing with migrants from the Old World.
In Neocene, Eurasia and North America appeared connected once again by the mountainous and cold Beringian land isthmus. Therefore, either flying animals such as birds and bats, or cold-resistant species of northern fauna participated in this faunal exchange. There are only few species of hoofed lagomorphs in North America, and native ungulates such as asinohippus and deer did not enter Eurasia from North America. Predatory beasts are more actively using the Beringian Isthmus for resettlement – berls represent an example of it. But in general, the fauna of carnivores of North America differs from that of the Old World.
One of the unique local predators is the niagwahe, a descendant of the American badger (Taxidea), but larger, the size of a small Holocene bear (body length about 2 meters), much stronger and heavier (hence the name, meaning monstrous big-headed bear in Iroquois mythology). It is covered with relatively short but thick dark gray hair (melanistic and “blond” individuals with straw-yellow hair are less common), with a short and thick tail. The black-and-white mask typical of the ancestral species has been preserved in this animal, but the white stripes have become thinner and brighter at the same time, making this mask more contrasting; its outlines are individual for each animal. The importance of this feature for identifying congeners has increased due to the fact that the snout of this animal has become shorter and flatter, allowing it to gnaw bones – this species is a Neocene analogue of the giant short-faced bear of Pleistocene epoch.
Like its ancestral species, niagwahe is a beast that is disproportionately strong for its height. With a blow of its paw, it can break the neck of a young peccason if the latter fails to escape in time.
Niagwahe is not a very fast animal, but it is very hardy, and it spends a significant part of its waking hours on the move. Due to its very large size, it is a worse digger than its ancestor: the beast digs only temporary shelters for itself, for example, to wait out the autumn rains and the rare but strong snow storms that sweep over the prairies of Neocene North America in winter. The rest of the time, this animal wanders in search of food and from time to time – a breeding partner. The shelter of this animal is a short but very wide burrow, ending in an extensive chamber where the animal can lie with its paws freely extended. Usually, such a shelter is arranged near noticeable features of the landscape like large stones, groups of trees or shrubs.
Niagwahe is a non-territorial species, but solitary and aggressive towards its congeners for a significant part of the year. In spring, females of this species emit a specific odor, which means they are ready to mate, and they stay in a limited area, marking it with urine and droppings. Males follow this scent, and if two or more males meet near the same female, they will fight for the right to mate, sometimes to the death. The female doesn’t care who the winner is – these animals have no personal sympathies. Mating itself passes quickly, and this completes the male’s contribution to procreation. He can even eat the cubs if he finds them, so after mating, the females leave the territories where the males roam, and they also behave very carefully at the lair.
Delivery takes place at the beginning of winter, with only 1-2 cubs in the litter. Closer to this time, niagwahe female repairs its shelter and, just before giving birth, eats almost nothing, living off the reserves of subcutaneous fat. Cubs grow quickly, and by the beginning of spring they are ready to follow their mother, but they continue to depend on her for the next year; at this time, the female does not mate. The young beasts spend the winter with their mother, but the following spring, the female drives the young away and prepares for a new fleeting “marriage.”
Niagwahe’s diet is mostly meat-based, including various animals, from peccasons to earthworms and steppe toads, as well as carrion. This animal eats vegetable food – mainly various tubers and roots of steppe grasses, as well as berries – less often. It may well take away other predator’s prey, even if it belongs to a pack of luparduses or a lone balam; however, the latter one itself manages to take prey from niagwahe sometimes and is dangerous for young animals just starting an independent life. Giant turtles sometimes manage to catch and drown this beast by attacking it from under the water at a watering hole, but on land the roles can change to opposite ones: niagwahe has enough strength to turn the reptile on its back and tear the meat out from under the shell. Although its claws are blunter than those of large cats, niagwahe can simply break the plastron of a turtle, even a very large one.
Puberty in young animals occurs at the 4th year of life, and the average life expectancy of niagwahe is 27-30 years.

Neosurilio (Neosurilio zebropygus)
Order: Carnivores (Carnivora)
Family: Mustelids (Mustelidae)

Habitat: forests of the east of North America and along the coast of Gulf of Mexico.
In epoch of biological crisis at the boundary of Holocene and Neocene the species had not having strict specialization received advantage in survival. The part of these species belonged to the group of synanthropic ones, and had adapted to live near people, having received from it additional benefits – an abundance of forage, refuge and rather quiet existence. But after human disappearance all species had received equal opportunities for further evolution.
Among mustelid family among survived ones there were North American skunks – the omnivores having an effective way of protection against enemies. One of descendants of spotty skunk (Spilogale gracialis), neosurilio (“surilio” is the name of one species of skunks in human epoch) lives in Neocene epoch in forests of North America. It is the ecological analogue of badger, the sluggish plantigrade animal having massive constitution. Length of body of this animal is about 70 – 80 cm, and length of tail is about 40 cm.
Neosurilio is noticeable from apart due to contrast warning colouring. The animal as if consists of two halves sharply differing by colouring. On back part of body, hips and waist there are alternating black and white strips (hence the scientific specific name meaning “having back of zebra”). Tip of tail is also white. Forward part of body of neosurilio is brown with white throat and stomach. Around of eyes there are “glasses” of white wool, and on top of head there is black “cap”.
Neosurilio has kept way of protection characteristic for skunk: it defends against enemies splashing smelly liquid from strongly advanced anal glands. In special sacs the oily liquid containing ethylmercaptane accumulates in amount enough to make some “shots” in succession to distance up to 3 meters. Before application of the weapon animal shows to aggressor the black-and-white back, having turned it to aggressor. At aggressively behaving neosurilio wool on back part of body rises on end and fluffs, increasing a little the visual sizes of this part of animal. If this warning had not worked, jet of smelly liquid flies to predator.
Neosurilio consumes various kinds of food, and due to the omnivorousity it does not stay hungry in any district. On forepaws of animal thick strong claws grow, with which help neosurilio easily digs out holes of small animals and gets roots and tubers of plants. More often neosurilio eats small animal – invertebrates, amphibians; also it ravages nests and eats eggs and nestlings of small birds. Up to half of diet of this animal the vegetative food makes – tubers, roots of plants and berries. Neosurilio eats food “aristocratically” – it sits on hind legs and brings it by front paws to the mouth. At the end of summer and in autumn neosurilio almost completely passes to vegetative food, and during winter and spring food shortage does not squeamish about carrion. Using the chemical weapon, neosurilio behaves very impudently, and can drive away from prey even large predators.
Each individual builds in the territory some temporary shelters and spends the night in them during wandering on the territory. Also neosurilio does not overlook to mark border of territory, splashing some drops of combat liquid on roots of large trees. The female ready to birth of posterity becomes homebody. Right before birth of posterity she stays best arranged shelter, and starts to expand it even more. She digs a hole up to 5 meters deep with several emergency exits. Pregnancy at neosurilio lasts about three months, and proceeds from the end of winter up to middle of spring. The female gives rise to 2 – 3 large cubs. They are born blind and deaf, but already at birth are covered with wool. The female cares of them for a long time, feeding them by milk up to 4-month's age. But to this time cubs already develop enough to leave a hole and to follow the female. At this time at them also odorous glands develop and they become able to splash smelly liquid. Young animals spend the first winter with the female, learning the search of food, and leave her shortly before courtship season when she starts to behave aggressively to them.

Miquiciyac (Miquiciyac myrmivoris)
Order: Carnivores (Carnivora)
Family: Skunks (Mephitidae)

Habitat: variably humid forests and rainforests of Central America.

Picture by Wovoka

Skunks form a group of slow-moving unspecialized predatory mammals limited in their distribution by New World. Due to their low specialization and wide range of food consumed, they have successfully survived the human era and are a common component of the Neocene fauna of the Earth. The largest species of these animals is miquiciyak, a descendant of the striped hog-nosed skunk (Conepatus semistriatus), beast the size of a small bear (weighing up to 60-70 kg).
The origin is easily discernible in the appearance of this species. It is a stocky plantigrade animal with a large head and clawed paws. The main body color is black, with two white stripes of elongated hair extending from the head to the rump. Tail is long (more than a quarter of the body length), with long thick hair, fluffy, black with a white tip.
Despite its size, miquiciyak is a fairly harmless animal that feeds on various small animals, although it can also feed on berries and fruits. It readily digs up rodent holes and ravages the nests of ground-dwelling birds. The animal has thick bristly fur on its muzzle, which protects it from insect penetration to the skin. The muzzle itself is elongated – longer than in coati. The ant hunter’s outfit is complemented by a sticky long tongue and large thick claws on its front paws.
When an animal wants to feast on ants, it tears open an anthill, and then urinates on or near it, spraying the ground with a stream of pungent-smelling urine. This puts the ants in a state of panic, and they stop stinging and don’t get in beast’s eyes. Hence the name “miquiciyac”, which can be translated from Nahuatl (Aztec) as “the smell of death” or “smelling of death.”
Miquiciyak especially likes to attack megacolonies of pochteka ants. First, it eats clusters of mealybugs on the bushes around the megacolony, and then it attacks anthills. It can partially destroy no more than seven to ten ant nests at a time, which is just minor damage for a megacolony with thousands of nests. Due to the omnivorous nature of the animal, its droppings later turn out to be a good fertilizer for calatheas cultivated by pochteka ants. It also likes to ravage bee nests, for which it has to climb trees.
Miquiciyak is a solitary animal, active at night and in the morning. It is only in spring during the mating season that animals gather in groups: males mate with females and fight for this right with rivals. Breeding season begins in early spring and lasts 2-3 months. Pregnancy lasts 4 months. There are up to 7 cubs in the litter; they are blind and hairless, but have already developed scent glands, which they will need in the fight against predators until they reach a large size, when no predator will dare to attack them. The female makes a den for her offspring among thorny bushes. Young miquiciyaks become independent by the age of 3 months, and reach puberty by the end of the second year of life.
Life expectancy reaches 22-23 years, and in large males up to 25 years.

Common fruit civet (Paradoxuroides frutophagus)
Order: Carnivores (Carnivora)
Family: Palm civets (Nandiniidae)

Habitat: tropical forests of Central Africa, forest canopy.

Picture by JOrnitho

In Holocene Equatorial Africa was a sanctuary of African palm civet (Nandinia binotata), an arboreal civet-like mammal. In fact, this animal isn’t a true viverrid, but a member of it’s own family inside the feliforms. African palm civet survived in Neocene and gave rise to new genus.
A habitant of the forest canopy, fruit civet is a very agile animal in the trees, being capable to grasp branches equally well with its fore- and hind paws and can hang from branches only on one foot and use its long tail for balance. This way it takes its main food – fruits. This species rarely descends to the ground, being capable to jump from a tree to another – a necessary ability, since its habitat represents dense tropical forests of Congo Basin.
Fruit civet is similar in appearance to Holocene palm civets of the genus Paradoxurus, true members of viverrid family. It has a slender, cat-like body, small head and large eyes. Its body has 45 to 56 cm of length and tail measuring 34 to 54 cm; males usually are larger than females. Its legs are long, with cat-like feet and semi-retractile claws. Its fur is dense and soft, and the coat is greyish brown, with dark spots on the back. There is also a black stripe coming from the forehead, along the spine and ending in the base of the tail – this feature is present in all species of the genus. Dark patches of wool are present beneath the eyes, which are offset against the reddish brown fur of the chin and throat. Tail is cross-striped with thin black rings. This species is nocturnal and crepuscular, with its highest levels of activity following sunset and just prior to sunrise. During the day, these animals rest in hollow trees.
They communicate with each other using sounds, scents, and visual signals. Their scents are sweet, similar to ripe fruit. Both males and females scent mark in their home ranges. Females mark their territory using scent glands on their flanks, hind legs and perineum. Males mark less frequently than females, often spraying urine, rather than using their scent glands, and behave so primarily during the breeding season. Scent marks of both sexes allow individuals identifying the reproductive and social status of other civets. Fruit civets also defecate at specific latrine sites, which are often located at the edges of their territories, and perform a similar function to other scent marks.
Fruits, mainly figs, make up the most part of its diet, but, when necessary, these animals can eat small vertebrates like birds, mammals, frogs and lizards. Eggs are also consumed. They locate their prey primarily by scent, chasing them agilely through the trees, and kill it with a bite to the neck like felids do. To reach larger fruits they stand up, using their front paws to hold the fruit and proceed to eat, while using their tail for balance.
This species is solitary, only meeting in the breeding period that starts in the last days of the dry season. In rainforest areas breeding season takes place the year round. Female leaves a trail of scent for the male to follow; when he finds her they copulate. If another male finds them, they will fight in the trees, chasing one another through the branches until the loser runs away. The victorious male will stay in the female’s territory for two weeks, making sure that no one another male appears there.
After a gestation period of 12 to 13 weeks, up to six cubs are born in a hollow tree. They start eating solid food at around seven weeks of age, and are fully weaned at four months of age. Being five months old, they are skilled in foraging for food on their own. At the age of seven months they leave mother’s territory. When 19 months old, they start marking their territories, and are sexually mature at the age of two years. The lifespan of fruit civet is about 13 years.
Other species of this genus exist in Africa:
Ring-tailed fruit civet (Paradoxuroides annulatus) lives in the forests of the Atlantic coast of Africa. This species has body length of 41 to 52 cm and tail 34 to 50 cm long. Ring-tailed fruit civet is similar to the nominal species, but the rings on its tail are wider and more accentuated, justifying thus its name. Its fur is pale brown with small spots.
Masked fruit civet (Paradoxuroides civetta) is less arboreal and frugivorous species of this genus. It lives in woods and savannas of Central Africa. Its lifestyle is similar to that of the Holocene African civet (Civettictis civetta). It has body length from 42 to 54 cm and short tail 29 to 36 cm long. Its main characteristic is a spot of black fur around eyes similar to a mask. The general fur coloration is brown with dark spots and tail has thin dark rings.
Banded fruit civet (Paradoxuroides fasciatus) inhabits coastal forests of Eastern Africa (Tanganyika Passage). This species grows to 43 to 53 cm with a tail measuring 35 to 52 cm. Its name comes from four dark bands on its back. Background color of fur is reddish brown, it is spotless. Tail has thin dark rings.

Owuo (Deinonandinia owuo)
Order: Carnivores (Carnivora)
Family: Palm civets (Nandiniidae)

Habitat: Equatorial Africa, tropical forests.
Unlike their closest relatives, viverrids, which gained an advantage during the ecological crisis of Early Neocene and rapidly increased their species diversity, palm civets survived only in relict islands of the African jungle. The evolution of each of their relict populations progressed in its own direction, therefore, with a relatively small species diversity, omnivorous animals, active predators and scavengers are present among the descendants of Nandinia. The largest predator of the African tropical forest is owuo (death in the mythology of Ashanti tribe).
Owuo resembles a large marten in its physique: body length is 90-140 cm, tail is 80-100 cm, and weight is up to 60-65 kg. The animal climbs trees with an effort, preferring to climb vines and sloping trunks, and spends much more time on the ground. Wool is ochre-brown with yellow spots on the muzzle, cheeks, throat and chest. The tips of the paws and tail are dark brown. The male is larger than the female and owns a larger territory; animals of both sexes are solitary, with the exception of females with litters. Owuos are strictly territorial: both males and females do not allow mature adults on their possessions. The boundaries of the territory are marked by secretions of musk glands, which have a pungent odor, noticeable from afar. In the case of claims to territory by an adult relative, fights are usually quite violent, often ending with the death of one of the animals. Also cases of cannibalism are not uncommon.
Owuo is a ground-dwelling predator that feeds on large mammals: false deer, large monkeys, cubs and juveniles of large forest antelopes. Less often, it hunts birds and reptiles, and also fishes in forest ponds after river floods. Most often, owuo lies in wait for prey at a watering hole or near the animal trail. When attacking, the beast tries to knock the prey down and strangle it, squeezing its throat with jaws. Less often, the beast knocks prey on its stomach and bites into the back of the head.
The mating season is not pronounced; the female signals readiness for mating by changing the smell of musky secretions, strongly attracting males from neighboring territories. Up to three competing males can gather in the female’s territory. For a ready-to-mate female, battles go on to serious wounds, sometimes ending with the death of one of the rivals. 100 days after copulation, the female bears 3-4 cubs; she hides them in the den, transferring the offspring to a new place several times. At the age of 2 months, young animals leave the den and go hunting with their mother, and at the age of six months they are already independent. At this time, a significant number of young animals die, accidentally entering the territories of adult relatives. Puberty in females occurs at the age of 3 years, and a year later in males. Life expectancy reaches 20-25 years.

Ursine civet (Ursivetta aromatica)
Order: Carnivores (Carnivora)
Family: Civets (Viverridae)

Habitat: mountain woods of Southern Asia.

Picture by Alexander Smyslov

Mass extinction of live creatures at the border of Holocene and Neocene had given few chances of survival to animals weighting more than 20 kgs. Predators dependent on abundance of large prey – cats, dogs, hyaenas and bears have especially suffered from it. But small predators like raccoons, weasels and civets have easily survived and have “privately divided” the planet: weasels and their descendants became main predators of temperate and cold areas of Earth, and civets were spreaded in tropical zone of Old World. Only in Africa and partly in America relic representatives of cats, descendants of small cat species compete with them. Holocene representatives of civet family by the constitution are analogues of primitive predators of early Cenozoic, therefore it is possible to assume, that they have the big evolutionary future. Among them there are ecological analogues of omnivorous bears and carnivorous cats, therefore it is possible to assume, that in the future they will occupy place of these animals.
Ursine civet is the huge representative of civet family. This animal is similar to bear with long tail (prehistoric analogue of ursine civet is the huge fossil marten Perunium dwelt in Eurasia). Constitution of this animal is, however, more graceful, than at bear: neck is longer and more mobile, and muzzle is more extended. Adult animal weighs up to 250 - 300 kg (males are larger). Legs are almost plantigrade, with long non-retracting claws. Fur of animal is rich and rather long (the animal frequently meets in mountains, sometimes in summer rising up to zone of Alpine vegetation), chestnut-brown with mesh white pattern on neck and back. On tail there are some cross rings of white wool, the tail tip is black. With the help of tail position ursine civet expresses its mood at the meeting with neighbours. In the basis of tail there are repugnatorial glands which emit pleasant musk smell for territory marking.
This animal is solitary one living in territory numbering some square kilometers in area and strictly protected from neighbours. Only female and cubs can live any time in group.
The ursine civet is omnivorous species with deviation to predating. Teeth at it are wide, knobby and dulled – vegetative food makes about 40 % of diet. Among plants ursine civet prefers fruits of different palms rich in oil. Also it digs out by claws roots of huge grasses of family Apiaceae growing on mountain slopes, and tubers of various wood grasses. On river banks ursine civet eats roots of reed mace and other marsh plants. The food of animal origin includes larvae of various insects, frogs and lizards, eggs and nestlings of ground birds. If there is an opportunity, ursine civet willingly eats carrion and attacks cubs of ground animals. Due to claws this animal can climb trees, ravaging bird nests.
Ursine civet is mainly day time animal. It spends night in shelter which it is usually a little number in its territory. From time to time animal moves to other shelter, giving to ants and the other insects the right to eat staying in lair litter larvae of fleas and ticks. For disposal of parasites animal willingly bathes in river and wallows on odorous grasses, especially on greenery of plants of Apiaceae family (having eaten its roots).
Borders of territories can be broken only in season of pairing. Usually on border of possession of several animals there is special remarkable place like alone growing tree or large stone. Animals make here original “message board”, marking it with odorous secretions. When the male notices on smell, that the female is ready to pairing, he puts the mark atop of mark of this female, and waits nearby from “message board” driving away other males. Also he puts marks in territory of chosen female: peels bark from tree and marks this place with odorous secretions, declaring about its presence. When the female comes to “message board” and sniffs at it, she becomes acquainted “in absentia” with the male, and if the male is pleasant to her, some time it allows him to remain nearby for pairing.
When the female feels approach of pregnancy, it banishes out the male, sometimes should win anew his own territory if on it in his absence the neighbour had lodged. Pregnancy lasts about five months. Shortly before cub birth the female builds lair – she digs out hole under tree roots or finds ready cave in mountains. She drags moss and branches for litter, and carefully hides traces of her presence near to chosen refuge.
In pack there are usually two cubs though sometimes there are triplets, and young females bear only one cub. Young growth is born blind and with closed ears, covered by short wool. Colouring of newborn cubs is spotty: chestnut stains on red or straw-coloured background (characteristic colouring of Asian civet (Viverricula), an ancestor of the ursine civet, was spotty), later cubs darken. At ten-day age at them eyes and ears open, and month-aged cubs already can play near lair entrance. At bi-monthly age cubs leave shelter, and female teaches them in ways of food getting. Young growth stay with mother up to eight-monthly age then starts to live independently. Sexual maturity comes at them at three-year age, and life expectancy can reach up to 30 - 35 years.

Pardinia (Pseudacinonyx gracilis)
Order: Carnivores (Carnivora)
Family: Civets (Viverridae)

Habitat: savannas and light forests of Southern Africa.

Picture by Viergacht

Mass extinction of large herbivore animals has caused disappearance of large predators eating them. After stabilization of situation and restoration of biological balance as the reply to evolution of herbivores large predators have started to appear – they were descendants of rather small forms which have survived during mass extinction.
Pardinia is one of such predatory animals, the descendant of genette (Genetta genetta), widely spreaded in Holocene at the territory of Northern Africa and Southern Europe. Its close relative is the huge deadlynetta (Necrogenetta deima), living in North-African savannas. But if deadlynetta is the specialized sabertooth hunter for large prey, pardinia is graceful analogue of the cheetah chasing swift-footed herbivores. By constitution pardinia resembles fleet dog with long tail and rather short muzzle. Height of animal at a shoulder is about 80 cm, body length is up to 120 cm, tail lenght is about meter; back legs are little bit longer than front ones. Body of pardinia is covered with short wool, on edges of ears there is fringe of long soft hair. Wool is straw-coloured with scattered brown stains on back merging to longitudinal strips. On throat of males there is big white spot bordered by dark-brown strip. Head of pardinia is similar to cat’s one, but is more extended. Canines are well advanced, their ends are visible from closed mouth of animal; bases of canines are very wide. Chewing muscles are well advanced: animal kills catch by bite in backbone or in the basis of skull.
Similarly to cheetah pardinia chases catch by fast throw. But as against cheetahs it also can chase lonely catch walking for a long time, yet will drive it up to exhaustion. Chasing prey, pardinia tries to fall catch down on the ground by impact of paws against side or shoulder, and then presses it by own weight against ground and bites in backbone.
Pardinia is solitary predator. Each female has territory marking it with secret of musk glands. Male, as a rule, has no constant territory: he wanders on territories of several females, remaining for the pairing period at one of them. Pregnancy lasts for 3 months. Shortly before cub birth female builds shelter in rich bushes or among stones where it gives rise to posterity: 4-6 cubs. Cubs are born blind, covered by dark one-colour wool. Later their colouring replaces to motley one, characteristic for adults. Cubs develop rather slowly: they start to leave shelter at monthly age, and study to hunt approximately from three-monthly age. About half-year they hunt together with mother, leaving her shortly before occurrence of new pack. Sexual maturity at young animals comes at the second year of life.
Pardinia hunts mainly quickly running herbivore animals - hoofed mammals, kept in Southern Africa as relicts of Holocene fauna. Hunting usually occurs on dawn though the female having cubs can hunt even in hottest time of day. Pardinia creeps to herd hiding in bushes and grasses, stopping at slightest sign of alarm at herbivores. Having chosen prey animal tries to catch it by one throw – pardinia is not able to run fast at long distance. Usually only every 6-th or 7-th attack ends successfully.
If number of large catch is not enough, pardinia willingly foods with small vertebrates – frogs, lizards and also birds. Dexterity of the pardinia is great: it can drop flying up birds in jump by long paws.
Organism of pardinia as against to organism of deadlynetta related to it works literally “for deterioration” – during run plenty of forces is spent. Therefore life expectancy of this animal is not so great: in total up to 12 – 14 years.

Gelluda (Pardonetta gelloudes)
Order: Carnivores (Carnivora)
Family: Viverrides (Viverridae)

Habitat: forests of South-East of Europe, forested areas of Fourseas coast, Caucasian Peninsula.
During Holocene, the human epoch, the native European fauna had reduced in number and in diversity. Many groups of animals, especially the large-sized ones, did not go through co-existence with humanity and died out without living descendants. Among them there were carnivorans – wolves, brown bears, European lynxes, etc… They had been replaced by the descendants of the predators of the “second wave” – mustelids and viverrids, including the descendants of the common genet. The panther genet inhabits the west and also in center and in the south of Europe, and to the east it is replaced by gelluda, a closely related species.
Like its relatives, the panther genet and the deadlynetta, gelluda is a very large animal, which reaches 160 centimeters in length (tail length is about one meter) and weighs approximately 70 kilograms. Its fur has grayish-white or pale yellow color, on which there are darker spots of irregular shape that merge to vertical stripes on the rear half of body and into rings on tail.
The appearance of gelluda has clear features of specialized predator: in has a robust skull and sharp teeth, especially the incisors. Unlike the deadlynetta, it does not have sabre-like canine teeth – on the contrary, its canines and incisors are close in size and are equally sharp, capable of breaking through almost any skin and of cutting meat. The molars, on the contrary, are blunt slightly and act like forceps. They are capable of breaking through even bones of medium thickness.
The muzzle of this animal is shortened and has strong jaw muscles – the role of gelluda in ecosystem is like the role of hyena, because it is able to eat its prey including the most part of bones.
When hunting, gelluda prefers to use its claws and weight, but not its teeth on contrary to felines: after jumping out from an ambush, it smashes into the side of herbivore, and begins to rake it with claws, trying to bring down its prey. Pain, the loss of the blood and the weight of the predator force its prey to fall and gelluda usually bites through cervical vertebrae of its prey to kill it. Gelluda hunts stronger and larger herbivores more carefully, putting smaller wounds to it and chasing it for a long time. Gelluda almost always hunts on the ground, and almost never uses trees for this purpose; therefore its basic prey includes medium-sized and large animals rather than the small ones, but during the period of hunger (usually in winter) it is capable of eating any animal, which it will be able to overpower.
In contrast to their relatives, gelludas are comparatively sociable animals, and live usually in pairs (both parents rear their 2-4 youngs), and in winter several (usually 2-3) pairs can act together, attacking even such animals, which they would not risk attacking in spring or in summer. At this time the territories of these animals are also used in common.Sometimes lonely animal joins the family and forms a pair with one young animal.
The mating period begins at the end of winter. At that time gelluda females begin to leave odorous marks on trunks of trees, stumps, large boulders and so forth. Males find these markers by smell and find females ready to mating following their marks. If several males gather near one female, they fight, punching each other on the snout with their front paws. They sit on rear ones when dueling. Head and shoulders of adult male may be covered with a pattern of numerous scars, the traces of such duels. If the pair of adult animals is stable, they do not take part in mating duels and behave aggressively to contenders.
In the second half of spring the females give birth to cubs covered with brighter and monotonous fur (melanistic gelludas appear in population rarely); usually it happens in secluded place, in natural shelter or in specially made lair. The female rears them with milk for the first two or three months, but in the middle of summer young animals leave their home forever, and at the autumn they are ready to follow their parents and to accompany them on the hunting.
Life expectancy of this species is 20-25 years.

Maladomini (Pardonetta maladomini)
Order: Carnivores (Carnivora)
Family: Viverrids (Viverridae)

Habitat: mountains of the East African microcontinent (Zinj Land).

Picture by Tony Johnes

Like mustelids and to a lesser extent raccoons, viverrids achieved very significant success in Early Neocene. While some large carnivores, such as bears, have almost disappeared from the face of earth, these small and medium-sized omnivores have successfully occupied some of the vacated ecological niches, giving rise to new species in the course of evolution after the human disappearance. Among them were descendants of the common genet (Genetta genetta) – large deadlynettas and smaller and lightly built panther genets live in Africa. Some of the ancestral forms of these species were isolated in the east, in Zinj Land. Maladomini, another large predator species of African origin, lives here on the mountain ranges.
Maladominni is a fairly large animal, up to a meter tall at the shoulders and weighing up to 90 kg; it is an equivalent of a leopard in Zinj Land. It prefers to stay in the mountains, parting habitats with noonda, a large cat descended from a leopard that prefers forests on the plains. The typical spots of the ancestral species have merged into longitudinal stripes in maladomini, and the back of this animal is black or dark brown, which creates a kind of obscuring shadow when maladomini hunts. The background coloration of wool is rusty-yellow, lighter in individuals from the highlands. Sometimes “pale” individuals are born, whose background color is straw yellow, and the spots on the skin are beige.
With its proportions, maladomini resembles a cross between a leopard and a marten. It has short, strong legs (the hind legs are slightly longer than the front ones), a flexible elongated body and a long tail. This beast has a flexible spine and can make jumps up to five meters long from the ambush. During the jump, the tail helps to keep the correct body position.
Maladomini is a predatory beast, but unlike deadlynetta, it lacks saber-like canines; like panther genet, it is an opportunistic beast that eats whatever food it can find. Obviously, this circumstance explains the success in competition with the ancestors of nunda, which deviated to specialization in large prey hunting. Usually, the descendants of Holocene rodents and hyraxes become the prey of maladomini, but it is able to prey on a primate, ravage a bird nest and catch a small python or a large lizard. Maladominis are good climbers and jumpers, but they have too short legs for fast running and a long chase, so they prefer to ambush large game. Actually, this is the optimal hunting tactic when hunting in the mountains, where there is a high probability of injury during high-speed running. If the first jump to the prey was unsuccessful, the predator can make up to three jumps in a row, chasing the fleeing prey, but if it fails to catch up with it, it stops chasing.
Like most large predators, maladomini is a solitary territorial animal: each individual owns a defined territory, which is marked with odorous marks and urine. After the trespassing, the fight follows, which is quite violent. Males of this species are larger than females and guard their territory much more strictly. Sometimes a fight between males can be fatal.
In the middle of the dry season, maladomini males and females begin to call each other with drawling yelping, which spreads far between the rocks. This yelping signifies the search for a mate, and then males and females can freely violate the boundaries of territories, searching for each other. Maladominis do not form permanent pairs, and after mating, the animals leave each other.
Maladomini females give birth to 2-4 cubs by the beginning of the rain season, choosing a reliable shelter for this purpose: a deep wide burrow, a cave of natural origin, and even a large bird nest made on the rocks. Unlike the cubs of some other carnivorous mammals, the young maladominis grow quickly and become independent by the end of the year. Puberty occurs in the second year of life, and the average life expectancy of maladomini is 12-15 years.

Squirrel mungo (Mungartes scandens)
Order: Carnivors (Carnivora)
Family: Viverrids (Viverridae)

Habitat: tropical rainforests of East Madagascar.

Picture by Timothy Donald Morris

During the climatic changes marked the change of geological epochs, the area of tropical forests of Madagascar was reduced up to several isolated sites in river valleys. Large forest species like Malagasy fossa had died out, but some small omnivorous predators had successfully survived. Among them there were rather small Malagasy mongooses (Galidictis), whose descendants have added new fauna of Madagascar.
In forests of Madagascar of Neocene epoch small animals can not feel like in full safety – at night one of local predators goes to hunt. Medium-sized mammal looking like squirrel quickly skips from one branch to another. It is about cat-sized, but looks larger because of long fluffy tail. With the help of such tail animal can change direction jump and support balance on branches and in jump. This creature is a squirrel mungo, one of Neocene Malagasy predators, ruthless hunter of any animals weighting up to 3 – 5 kgs.
The skin of squirrel mungo is rusty-red, patterned with wide longitudinal strips of black color, breaking on shoulders to separate strokes. Tail is red with white tip, on eyes there is white “mask”; hands and feet are dark grey.
Paws of squirrel mungo are rather long – in proportions animal looks like huge squirrel. Claws are rather short, but fingers and toes are long and tenacious - animal is good tree-climber and spends the whole life in forest canopy.
Muzzle of animal is extended; ears are short and rounded. Canines are long, slightly juiting out from mouth. Squirrel mungo takes prey by forepaws, presses to branch and kills, putting deep bites to it. Squirrel mungo eats reptiles, birds and small mammals, and can attack even lemur cubs. It also supplements diet with bird eggs and insects. This predator eats small prey like squirrel, holding it in forepaws.
Squirrel mungoes live and hunt in pairs keeping together till some years, and sometimes till the whole life. Hollow of large tree, especially if the trunk is rotten from within to needed depth, is best dwelling for these animals. In afternoon time squirrel mungos sleep, and right before evening they begin the restless life: stretch, cleaned wool for some time, and go to search for food, renewing boundary marks in passing. Animals mark borders with musk secreting by glands in the basis of tail. For this purpose this mammal nestles back against tree trunk or branch, and rubs against this place for some time. Usually the couple of animals marks territory in common, putting a personal mark near to partner’s one.
The pair protects its fodder site in common. If the stranger interferes the site occupied by couple of animals, lawful owners of territory meet it, loudly squalling and keeping nervously shivering tails up. Usually single animal does not get involved in fight with breeding couple and leaves another’s possession.
Two times per one year the female brings posterity; in litter there is one cub differing from adults in monotonous reddish colouring without spots. It spends first two weeks of life in shelter (usually in tree-trunk hollow or in abandoned bird nest). When it gets stronger, parents start to train it in hunting receptions. Young animal keeps with parents almost up to the birth of the next cub at them. Shortly before delivery female starts to express aggression to its own cub. She can even kill it, protecting the future posterity if the cub appears not ready to begin independent life.
The young animal reaches about 2/3 of the weight of adult animal to the moment of exile from family. At the age of half-year young animals occupy their own territory and after two more months can bring posterity.

Sugar mungo (Floromungo flosculiphagus)
Order: Carnivors (Carnivora)
Family: Viverrids (Viverridae)

Picture by Alexander Smyslov

Habitat: tropical rainforests of Eastern Madagascar.
The tropical rainforest gives the huge variety of kinds of food to the inhabitants; therefore it is possible to meet the set of highly specialized species of animals here. Among them at times there are species depending on the most unexpected food sources.
Predators turn to vegetarians rather seldom. Pandas, partly bears, and the African palm-nut vulture among birds are the examples of this phenomenon known in human epoch. But in Neocene in Madagascar forests the descendant of carnivores evolved, which quite may add this list with itself – sugar mungo. This species of former predators lives in canopy of Madagascar rainforests at the great height. The small mammal with bright red wool and long tail quickly clambers among lianas and branches. It is similar to any rodent or small lemur, but at close examination first impression appears deceptive. It differs from primates in claws and short fingers and toes bearing characteristic small pads. Also it is lack of large incisors being a “card” of rodents.
This animal moves in a manner characteristic for predators: it quickly jumps among branches, frequently sniffing. And it seems that sensitive long nose prompts its owner where the food is. In several jumps small predator reaches the purpose: branches of plentifully blossoming tree. Having found recently opened labiate flowers emitting aroma with slight putrefactive shade, little mammal thrusts head in flower. In the weight it lowers the bottom petal, densely pressed against top one, and narrow muzzle allows it to penetrate deep into flower fauces. Little mammal does not search for small animals it can easily cope with – it feeds on nectar. When it pulls head out from flower, its nape appears powdered with brownish pollen. Having cleaned and having sneezed squeaky, sugar mungo gets into other flowers by turns, licking nectar from them and making pollination in passing.
Sugar mungo, perhaps, is one of the smallest and most specialized species of carnivores; it is the descendant of Malagasy mongoose (Galidictis). Having adapted to life in forest canopy, it has turned to skilful acrobat, and small size allows it to clamber easily on thinest branches. It is only about rat-sizeв one, though it seems larger because of longer fluffy tail. Bright red wool of sugar mungo is short and rich. Throat and breast are white, bordered with thin black strip. On back there passes black longitudinal strip; sometimes it is supplemented with pale faltering parallel strips on each side. Tenacious paws of animal are supplied with sharp bent claws, allowing clambering on branches and tree trunks. Tail serves as a counterbalance when this mammal moves on lianas and thin branches.
Head is extended and is on rather long and flexible neck. Brown eyes are large – sugar mungo has good color sight; it distinguishes the most part of colors (except for dark blue) and especially likes to feed on red flowers. Muzzle of animal is long and narrow, slightly lowered downwards; on each side of nose long whiskers stick out. Teeth are small and short – sugar mungo eats firm food seldom. But tongue of this animal is a principal organ of food getting. It can be put far out from mouth, and on its tip there is brush of fibers, assisting to gather nectar. In addition to nectar sugar mungo eats friable pulp of ripe fruits. Animal licks it by tongue from cracks in peel, or tears peel of fruit by claws for feeding. Occasionally sugar mungo catches tiny insects and slugs, supplementing a diet with necessary animal protein. Pregnant and nursing females, and also young animals especially frequently catch invertebrates.
Sugar mungo is a solitary animal and is active mainly in afternoon time. Females of this species are very much adhered to the territory, and each individual carefully marks borders of territory with musky smell. Males lack musky glands, and they have no constant territory which may be marked at all. Every male lives at the large site including some territories of females. Males are more tolerant, rather than females, concerning to each other and some animals can even spend the night in the same hollow.
This species brings posterity up to 3 – 4 times per year. In a litter there is only one cub, twins are rarity. The young growth is born rather advanced, covered with short wool. It is remarkable, that at this species habits like at cuscuses and lemurs were developed: the grown up cub leaves nest very early (at the age of one week, just having opened eyes), and gets on back of mother. It travels so approximately two weeks more, and then starts to follow mother independently. At this time it remembers species of plants having nectar-bearing flowers. At the age of two months it becomes completely independent and leaves mother which already bears the new cub at that time. Five-monthly sugar mungoes are already adult and also are capable to breed. Life expectancy is short, as well as at all small mammals: no more than 5 years.

The related species also lives in rainforests of East Madagascar – it is bee mungo (Floromungo apiphilus). This species differs from sugar mungo in dim brown colouring of the top part of body with longitudinal black strips on sides. Spots on its throat are yellowish and rather small.
The diet of bee mungo includes mostly honey which it steals in bee nests, and also larvae of these insects which represent the main source of protein of animal origin in its diet. It is dangerous to get such food: bees can kill small animal, having stung it enough of times. But bee mungo uses the special adaptation to ravage bee nests: it has strongly advanced musky glands, and the smell of their secretion frightens insects off. Getting into bee nest, animal lets out some drops of musky liquid. The extending smell forces bees to leave nest and to get off in dense clusters on branch at some distance while the animal quietly licks honey and eats larvae in their nest. In other features the biology of this species is similar to biology of sugar mungo.

Antamba (Antamba fadi)
Order: Carnivores (Carnivora)
Family: Malagasy carnivorans (Eupleridae)

Habitat: Madagascar, woodlands and savannas in the western part of the island.
In the human era in Madagascar island, the word “antamba” meant a certain kind of large predatory animal, perhaps a subfossil giant fossa (Cryptoprocta spelea). During the human colonization of the islands, large species of insular fauna were exterminated, but after the disappearance of humankind, a new stage in the evolution of island fauna began, already with the participation of descendants of introduced species. Most of the descendants of the endemic inhabitants of the islands appeared unable to compete with them, and analogues of some species that existed on the island before the human epoch no longer appeared. But in the fauna of Madagascar of Neocene epoch, there are quite a large number of descendants of the native fauna. One of them is the large predatory antamba, a descendant of one Madagascar mongooses species, the broad-striped Malagasy mongoose (Galidictis fasciata). Its close relatives are tropical forest dwellers – harmless sugar mungos of Floromungo genus and the small predatory squirrel mungos Mungartes, which took a different evolutionary path and became arboreal animals.
Unlike its arboreal relatives, antamba lives on the ground and hunts large animals. It is a massive mammalian species – the size of a small lion and weighing up to 150 kg. It has powerful paws and a long, thin, evenly pubescent tail. In its body proportions, this animal resembles a jaguar; adult animals cannot climb trees, and young individuals often climb sloping tree trunks while playing. Muzzle is shortened, somewhat resembles the muzzle of large cats, with strong jaws, which are used by this animal to inflict bites and crush the bones of prey. Ears are short and rounded, located on the sides of the head. Claws are of moderate length, sharp and non-retractable. On the front paws, the inner finger is equipped with a very large claw, like that of fossil marsupial lion (Thylacoleo) and Neocene daggerclawer cats (Pugionyx), and is adapted to inflict wounds to prey in the sides and belly. Antamba has a mottled skin: the background color is brown, and 1-2 rows of uneven light brown strokes stretch along its sides. Their pattern is individual for each animal. The sides of the head (cheekbones and part of the lower jaw) are also light brown. The tip of the tail is white with a brownish tinge. At the base of the tail large scent glands are located, that emit strong-smelling secretions.
Antamba hunts large native herbivorous mammals, mainly phobocorns and giant tenrecs. During the day, this animal is inactive and prefers to sleep in a shelter among rocks or bushes. At night, this animal hunts, renews its territorial marks and searches for mating partners. This animal resembles a feline in its hunting style: it silently sneaks up on its prey, using natural shelters and freezing in the grass for a long time, and then attacks with one short, quick rush. Antamba inflicts a strong bite and deep wounds with large claws of its front paws on its prey. If it is not possible to kill the prey immediately, the beast releases it, fearing hooves or horns, and follows its blood trail until it bleeds out. Before eating its prey, the beast marks the grass around it with its scent. If it failed to eat prey during the night, the animal remains in shelter next to it and eats it in the evening of the next day.
It is almost exclusively a nocturnal species. Odorous glands serve to leave scent marks on the borders of the territory, with which the animal communicates with its relatives without coming into direct contact with them. Antamba’s voice at rest is a low grunt; during conflicts, sounds of aggression can be heard – unpleasantly sounding squeals and hissing.
The territories of males and females largely overlap, but the female prefers one of these males and forms a family while raising offspring. The regularity in reproduction is not pronounced. There is almost always one cub in the brood, twins occur in about one out of ten cases. The lair is located in a wide hole or among bushes. As a rule, the female takes care of the offspring, and the male is mainly engaged in hunting. As the cub matures, the female begins to hunt (acting separately from the male), and later the cub begins to learn to hunt with her. The cub stays with its mother for a long time, almost 11 months. The female is ready to reproduce 2-3 months after the cub leaves her. Sexual maturity of a young animal occurs at the age of 2 years, life expectancy is up to 50 years.

Long-bodied pterogenettula (Pterogenettula prolonga)
Order: Carnivores (Carnivora)
Family: Civets (Viverridae)

Habitat: Equatorial Africa, the top level of rainforest canopy.

Picture by Alexander Smyslov

Development of various anatomical adaptations at live beings depends on features of their environment. And the generality of inhabitancy results in formation of similar adaptations at unrelated species. It has taken place in woods of Equatorial Africa where on top-sized trees many species of mammals able to make long jumps were developed. If the forest canopy is dense, in it tree-climbing animals receive advantages. But in friable multileveled canopy experts in long jumps dominate. And on top of food pyramide there is also living “glider pilot”, but it is a true predator.
Predator of the top level of African woods is the long-bodied pterogenettula, small animal with extended body. It had descended from one of species of wood civets managed to go through the time of active hunting in last equatorial woods of Africa.
Body length of this predator is about 30 cm at all, and tail lenght is about 20 cm. Externally this animal is similar to any small weasel: at the pterogenettula there are rather short legs and the extended head. The animal has “marble” spotty colouring of large ring-formed spots on light background. It makes this predator imperceptible on the background of bark spotted with shadows of leaves. On head there are dark strips between eyes and nose, needing for recognition of neighbours.
Extremities are rather short, supplied with tenacious claws. But the most remarkable feature of appearance of these small mammals is the presence of small flying membrane between front and hind legs. For improvement of its “flying” properties on edge of membrane the fringe of black fluffy fur (as on sides at Holocene monkey Colobus) is stretched. The long tail of animal serves as rudder. Skilfully using force of wind, the pterogenettula can make jumps up to 20 meters long, losing in height only 8 - 10 meters. Operating flight, the pterogenettula can even catch small birds, preying them in sudden jump from an ambush. If attack was unsuccessful, the animal simply continues a jump, and sits on a tree. Flying up to the final point of jump, the animal weakens flying membrane, and seizes by claws of all four paws branch or bark of tree. Also this predator is able to swarm up trees dexterously, being not inferior to any squirrel in speed. The pterogenettula frequently hunts also a way traditional for predators, chasing catch among branches.
Favourite catch of the pterogenettula includes birds, but also it frequently hunts lizards, squirrels and squirrel guenons - dwarf monkeys of forest canopy.
This animal is strict solitary predator. Each individual chooses to itself the certain site in forest canopy, reaching not only in sides, but also upwards. Borders are marked by odorous secretions of specific glands of anal area.
Seasonal prevalence in breeding of pterogenettulas is not present, and young animals may be met at any time of year. Per one year the female brings 2 packs (4 - 5 cubs in each litter). Young animals differ in darker colouring (light intervals between dark spots so are small, that colouring seems mesh-looking). Approximately at four-monthly age young animals start to study “flying” - to this time the flying membrane at them develops to the full. Sexual maturity comes at them at the age of 8 – 9 months, and life expectancy may be about 6 years.

Zibetonyx (Zibetonyx velox)
Order: Carnivores (Carnivora)
Family: Civets (Viverridae)

Habitat: steppes of Central Asia (to the east from Fourseas).

Рисунок Александра Смыслова

Evolution proceeds by certain principles and laws which were just in the past, and undoubtfully will be just in the future. Therefore it is quite logical to expect of recurrence in the future of some phenomena taking place both in the far past, and within people.
One of such phenomena, convergence with representatives of canine family (Canidae) and Neocenic African predator pardinia, is demonstrating by zibetonyx, the inhabitant of plains in Central and Middle Asia. This gracefully build predatory animal is the descendant of mongooses (Herpestes) widely settled in Asia. Ecological plasticity of these small predators has permitted them to occupy temperate steppes of Asia successfully. And specific conditions of inhabiting - open plains with high grass - had generated shape of new predator.
Being quickly running predator, zibetonyx has characteristic shape: at it there are long legs and flexible backbone, small head on rather long and mobile neck. Jaws of zibetonyx are long and rather weak, its head resembles canine one. As against cats and pardinia very similar to it, the zibetonyx kills catch not by one sting: the pack inflicts to the chosen prey numerous wounds and exhausts it by long pursuit.
At zibetonyx there are sharp sense of smell and good hearing: animal frequently should hunt in high grass where sight can be practically useless. Ears of zibetonyx are rounded and wide, but they are located at head sides as at its ancestors. On the top part of neck the mane especially big at the adult male grows.
Colouring of wool is yellowish with large brown spots merging on sides and back to short longitudinal dabs. Up to winter (in habitats of zibetonyx snow does not fall, but weather becomes appreciable more cold in winter) wool becomes longer and then the mane of males is almost not appreciable.
Zibetonyx is ecological analogue of wolf, but a little bit reduced size. Animals of this species hunt in packs up to 10-15 animals preying approximately goat-sized herbivores.
The pack of zibetonyxes represents clan with expressed social connections and hierarchy. Clan is formed of posterity of one parental pair: all females from packs remain in clan, and maturing males leave it. Females in clan appear connected by consanguinty and represent two – three generations of one family. Males come to clan “from the side”, and between them and main pair (clan founders) there are relations of submission. If friction between males appears strong, clan can divide at all.
The clan is original “super-organism”: harmonious collective hunting is much more effective, than single’s one. Zibetonyxes are specialized for hunting quickly running herbivores: usually harelopes are their catch. However the important place in menu of zibetonyx is occupied also with small catch: animal willingly eats lizards, birds and large insects – beetles and grasshoppers.
Main way of hunting is prey chasing. For this purpose zibetonyxes from one clan stay in line and hide in grass at some distance from each other. Some individuals (as a rule males are they) drive harelope out from herd and chase it to animals waiting in ambush. “Passing on” chased animal to each other, predatorss absolutely not for long time take part in hunting but can “give all the best” completely, similarly to cheetah. Because these animals combine hunting tactic of wolf and speed of cheetah it has allowed them to become successful and prospering plain predators in hunting.
Daily life of clan takes place near natural shelters – small groups of bushes in which females arrange little lairs and practically in common rear young growth. Here animals have a rest after hunting. Near shelters zibetonyxes keep rather carefully and silently, and do not hunt here to not unmask place where cubs are reared. But borders of clan are plentifully marked by urine and musk secretions of repugnatorial glands. Usually adult males put marks, placing them on big stones, bushes and trunks of lonely growing trees.
Cubs (2-3 in litter) are born blind and covered with short wool. Their colouring is very dark: brown, paws and ears colored black. For the fourth day of life at them eyes open and then they start to hear. And ten-day cubs already try to walk. Only first two weeks of life young zibetonyx knows exclusively care of native mother. Growing up, it becomes object of gentle care at once of several females of clan, including old ones which can not bear posterity any more. They play role of “baby-sitters” when clan goes hunting. Such feature raises chances of survival even at deserted cubs. One female is capable to bear posterity twice per year.
At the age of four months young animals already change youthful dark colouring to spotty adult one. They study to hunt about two months, and then when females of clan have new cubs, young males are driven away. They can live vagrant life on border of territories of several clans, satisfying by remains of their catch. Frequently young males form independent packs try to drive out adult males from any not numerous clans, or to drive off young females from near clans. Usually bachelors are much more aggressive than males have formed pair. They easily get involved in fights though they can suffer serious loss from strong clans: females protecting posterity can fight up to death. Usually many young males perish in such skirmishes, and sex ratio in generated and breeding clan is 1 male for 2-4 females.
Sexual maturity at females takes place at second year of life, at males – at third year. Life expectancy is about 15-18 years.

Mauritian paralutra (Paralutra nana)
Order: Predatory (Carnivora)
Family: Civets (Viverridae)

Habitat: rivers of Mauritius Island.

Picture by Pavel Volkov

The fauna of Mauritius Island had strongly suffered from people influence. Many species of animals representing groups which could not appear on island by natural way had been introduced to the island in different times. These animals were monkeys, rodents, various predators and domestic hoofed mammals. Such inflow of species new to the ecosystem of the island had taken place in very short term according evolutionary measures – within several centuries. As a result the native fauna and flora of island had degraded. People could interfere with influence of introduced species to the endemic nature of island with the help of nature protection actions till some time. But after the disappearance of mankind the rests of island primordial nature were destroyed by introduced species. In Neocene flora and fauna of Mauritius are presented mainly by descendants of introduced species had formed the complete and balanced ecosystem. In most cases inhabitants of islands differ in diminutiveness, and only few species of reptiles and birds are the exception. Descendants of introduced species had occupied all ecological niches were given to them by the nature.
Rivers of island are shallow and short. Descendants of the fishes introduced by people – true gourami (Osphronemus goramy) and goldfish (Carassius auratus auratus) live here. Occasionally sea fishes swim into the rivers of island, and there are some species of river shrimps and crabs. These species make the basis of food pyramid at which top there is one endemic species of predators adapted to life in water – the Mauritian paralutra. This animal is the descendant of mongooses (Herpestes) introduced to the island and perfectly swimming predator. Paralutra eats any water animals which can be caught, and supplements a diet with tubers and sappy leaf petioles of water plants.
Mauritian paralutra is a small animal. This is the natural phenomenon in the world of small island, where resources and vital space are strictly limited. Length of adult animal is about 60 cm including long tail. By appearance and constitution paralutra resembles true otters (Lutra) of Holocene epoch: this is a short-legged animal with flexible body and membranes between toes. Fingers of forepaws of paralutra are not connected by membrane. They are sensitive and mobile, and have small claws. With their help paralutra searches in thickets of plants for shrimps and small fish. On the coast paralutra clears and combs fur by fingers. The wool of animal has grey color, on throat there is white spot, and cheeks are also white.
Head of paralutra is flattened, with short wide nose and long postorbital part of skull. Eyes are shifted to the forward part of head and upwards, therefore animal can breathe and look over vicinities, having put out from water only a part of head. Above the nose of animal there is a site of hairless skin with which help paralutra digs bottom in searches of crustaceans and roots of plants. External auricles at paralutra are lack, and the ear aperture at diving animal is closed by ring muscle. Tail of paralutra is long, flattened, covered with naked skin. At movement under water animal presses forepaws to body, and swims, wavy beding by all trunk. For slow and maneuverable swimming among underwater thickets animal uses hinder legs.
Paralutra eats small fish, not attacking large fishes. Hunting animals try to push aside school of fishes to the bank and attack them in common. Also this animal eats shrimps and crabs, and ravages nests of coastal birds.
Musk glands located under tail produce plentiful oily secret with which help paralutra makes its fur water-repellent. To not frighten off fish, this product of secretion till the process of evolution had lost smell that is completely atypical for civet. This mammal smears secretions of musk glands on forepaws, and pounds secretions on fur, carefully rubring them in hairs and combing them by claws. Ritual of mutual fur caring helps to support friendly relations between the representatives of species living together.
This is sociable mobile animal. Paralutras settle on steep riverbanks by whole families including some females connected by consanguinty, and males not related to them. The family of these animals digs out some inhabited holes, one of which is occupied with main pair. These animals breed the year round. The female can bring posterity two times per one year, 3 – 4 cubs in one litter. Preparing to birth of posterity, female deepens the hole and digs out wider inhabited chamber, rather than usually does. Cubs are born blind and deaf, covered with short dark wool. They start to move in hole at the age of about 12 days, and monthly cubs already are able to swim as well, as adults. At the age of 3 months young animal becomes completely independent; half-year old female already gives rise to posterity.
Paralutras constantly support contact with each other with the help of voice. They can utter various sounds – they chirr, peep and whistle. At danger animals yelp like small dog. After feeding animals gather and clean wool to each other. At the rest paralutras are cautious and prefer to gather at shallows and small islands in the middle of the river where it is impossible to creep to them imperceptibly. At suspicious sounds and sudden occurrence of large animals at the riverbank they disappear under water. Main enemies of paralutras are maurosmiluses – small saber-toothed ground predators of feline family; in water some sea fishes swimming to rivers of island can attack these animals.

Eastern punia (Unaliurus orientalis)
Order: Carnivores (Carnivora)
Family: Viverrids (Viverridae)

Habitat: Far East, China, Amur Basin.
The warming of the climate in Neocene led to the expansion of the range of heat-loving groups of animals and plants. A significant number of African forms entered Europe through the Gibraltar Isthmus. A similar situation is taking place in the Far East, where a significant number of migrants from the Oriental zoogeographical realm have appeared. Among the mammals of southern origin, viverrids live in these places. One of their representatives is eastern punia, an omnivorous arboreal animal.
Eastern punia is a slow-moving viverrid species with a build similar to a red panda (“punya” is one of the names of the red panda). The animal has a powerful physique, muscular paws with an opposable thumb and a long prehensile tail. Eastern punia spends most of its life in trees, and only rarely descends to the ground.
The animal’s body length is about 50 cm, and the tail is up to 70 cm long. This animal has a short muzzle with rounded ears covered with thick hair on the outside. Limbs are five-toed, semi-plantigrade, with movable digits and strong claws. Pads of the paws are hairless, covered with hard wrinkled gray skin. Wool color on the back, sides and upper side of the tail is pale-yellow with small dark spots arranged in several longitudinal rows. On the belly and paws, as well as on the inside of the tail, the fur is white with a grayish tinge. Hands and feet are covered with light brown fur. Ears are lined with white hair, and the hair on the head is darker than on the body. Eyes are surrounded with rings of white fur, and the throat and chest are also white. White area on the chest is surrounded by a narrow strip of dark brown fur. Winter fur is lighter and thicker than summer fur; in this case, the spots on the back almost completely disappear. In older individuals, the hair on the head turns noticeably gray.
Eastern punia is good at climbing trees and can hang on its tail. It can run fast on the branches, but is not capable of making long jumps like monkeys do. If it is not possible to climb from one tree to another, the animal covers the distance between them on the ground. Also eastern punia searches for food on the ground, although it prefers to feed in trees.
This species is social: a breeding pair of adult animals stays together for several years in a row, and the juveniles of the previous year of birth live with them. Often a strong adult male gathers a group of 2-3 females. The group occupies a certain territory and marks with odorous secretions its borders and some of the most prominent objects located within the group’s possessions – the bark of tall trees and the upper part of large stones. The members of the group communicate with each other using a small number of sound signals, including hissing, barking and growling. The position of the tail is important in communication; being in aggressive mood, animal keeps its tail raised and its fur fluffed out, while a subordinate animal curls its tail and hides it under its body. Nevertheless, relations with congeners, even from other groups, are usually peaceful. Conflicts are resolved through postures, and only during the mating season do males treat each other very aggressively and fight for ownership of females. Young individuals having no permanent mating partner take part in fights most often. When attacking an already established family, the aggressor runs the risk of being rebuffed by all its members at once.
Eastern punia is omnivorous, but a significant part of its diet consists of vegetative food – leaves and young shoots, berries and fruits, juicy stems of epiphytic plants. Food of animal origin includes invertebrates, amphibians, reptiles, bird eggs and chicks. On the ground, eastern punia digs up roots and searches for small invertebrates.
The mating season falls in late autumn and early winter. The development of the embryos lasts about 50 days, but is prolonged due to the winter diapause. The birth of offspring occurs in early spring; there are typically 2-3 cubs in a litter. Shortly before giving birth, the female searches for a den – a suitable sized hollow at a height of several meters above the ground. The cubs are born blind and deaf, but having thick fur. They fully develop and leave the lair at the age of 3 months and live with their parents until the cubs of the next litter grow up.
Puberty in eastern punia occurs at the age of 2 years, and the life expectancy is about 15 years.

Grumbling ant-mungo (Myrmungopsis myrmivorus)
Order: Carnivores (Carnivora)
Family: Ant-mungoes (Myrmivoridae)

Habitat: Atlas Mountains, Middle East, Southern Europe (coast line of Mediterranean swamps).

Picture by Tim Morris

Some species of live creatures have success in struggle for existence due to development of habitats and food resources inaccessible to other species. This mammal species belongs to such animals. It is the representative of new family of Neocenic mammal, eating exclusively social insects. The ant-mungoes family had descended from civet family: some small species of family had specialized in feeding by insects, and further this specialization has resulted in occurrence of new group of animals. Any species of small mungoes - animals proved their success in struggle for existing - became direct ancestor of representatives of present family.
The ant-mungo during evolution has got common for insectivorous animals appearance features: at this animal there are wedge-shaped extended head, small mouth, reduced lower jaw and teeth. The basic feeding organ is tongue, capable to extend forward approximately for one and half lengths of head. Nostrils are located on tip of muzzle, during the feeding process they close and animal holds the breath. Claws on ant-mungo forepaws are long, during movement the animal turns them in and supports on the back side of hand similarly to anteater or gorilla (in these places “callouses” of dense thick skin develop). Claws are used for digging insect nests and for protection against enemies. The wool of ant-mungo is short, dense and rigid, bristle-like. It protects animal from stings of insects. Besides animal has significant immunity to insect poison. Colouring of wool is dingy: monochromic gray-brown, stomach is light grey, legs and tail are darker. Forepaws are shorter then rear legs; at movement the back of animal is inclined forward. Digging out an ant hill or termitary ant-mungo can stand on hinder legs for a long time.
The grumbling ant-mungo reaches length 40 cm (tail is up to 30 cm) and weighs about 5 kgs.
Ant-mungo leads social habit of life differing in it from other Neocenic “anteaters”. This species lives in families of 4 - 7 animals (breeding pair of adult animals and cubs of the current year). Family occupies rather extensive territory with thickets of bushes and light forest where many nests of termites and ants are located. Except for them animals eat small snails, swallowing them entirely with shell, and also larvae of beetles and caterpillars of butterflies. Animals communicate among themselves with the help of sounds similar to rumbling and grunt.
This animal lives in hot, almost waterless areas, therefore it shows greatest activity in twilight. The group of ant-mungoes spends day in temporary hole dug on the eve on morning, and at the sunset leaves it for feeding. In the evening animals eat mainly ants gathering in ant hill for the night, at night – by termites coming on surface, and gather snails crept out on plants covered with dew in the morning, or search for beetle larvae under stones and tree bark.
Pairing of ant-mungoes occurs approximately for two months before rain season, and cubs are born just in this season. It is justified biologically: milk producing at the female takes plenty of water, and in rain season it is easier to fill up internal water stocks. Once a year, in the beginning of rain season female gives rise to five - eight cubs. They are born blind and deaf, female hides them in specially dug hole. She feeds posterity, coming back in hole some times for night. At this time male shows original care of her: he gorges on for future use, and then in addition feeds up the female, belching food to her mouth.
At one month after birth the young growth already can follow adult animals, and the female actively trains posterity to search for food. Usually pack stays with mother up to the following season of pairing when the parental pair banishes posterity from the territory. The young growth reaches sexual maturity at half-year age, and life expectancy is about 8 years. Main enemies of grumbling ant-mungoes are predatory mammals and snakes, but most of all these animals perishes during long droughts.

Awfulest marafil (Marafil perhorridus)
Order: Carnivores (Carnivora)
Family: Hyenas (Hyaenidae)

Habitat: South Africa, mountains and plains.

Picture by Eugeny Hontor

In Neocene South Africa appeared separated from Holarctic zoogeographic area by the zone of impassable tropical woods. They had appeared when East Africa (Zinj Land) had separated from the main part of the continent, and the area of dry climate had considerably reduced because of evaporation of water from Tanganyica Passage.
The majority of groups of herbivores appeared in Neocene had not got here; therefore Southern Africa became one of places where many representatives of hoofed mammal fauna characteristic for Ethiopic zoogeographic area had kept. In South Africa in savanna descendants of water chevrotains similar to deer wander, and tall descendants of dwarf duiker antelopes similar to primitive giraffes browse foliage of trees. Representatives of animal kingdom of new epoch – huge descendants of pigs armed with massive bone outgrowths on head – also are found here. By the efficiency ecosystem of Southern Africa does not concede to North African savannas of early historical epoch.
The abundance of catch involves various predators, and relative stability of this region had allowed to some representatives of Holocene fauna of predators to be kept in South Africa. Among civets and cats of South Africa one local predator looks separated – it is the last representative of hyenas’ family. This family had been widely distributed in Eurasia in Holocene. Till the ice age some of its representatives had wandered in snow-covered woods of Europe, tolerating severe winters. But after mass extinction of hoofed mammals in the areas mastered by people the area of family was sharply reduced. In historical epoch the family was submitted only by five species, one of which was extremely rare.
Awfulest marafil (“marafil” is the Arabian name of hyaena), the descendant of spotted hyena (Crocuta crocuta) widely settled in past, lives in South Africa This animal represents the deification of “predator” concept, doubtlessly occupying the top of food pyramid in local ecosystems.
Awfulest marafil is the largest species of hyenas among ever dwelt on Earth, and, obviously, it is the largest representative of the carnivore order in Neocene. Growth of the adult female at a shoulder reaches two meters at weight about 700 kgs. Male is smaller, rather than female: it weighs about 500 kgs and differs in lighter constitution. By the appearance marafil resembles fossil Arctodus bear dwelt in Pleistocene at the territory of North America. The female of marafil differs in sloping back (back legs are shorter a little, rather than front ones) and wide chest. Forepaws at it are very muscular – with their help the animal knocks prey off feet. Feet at the female of marafil are rather wide due to what animal can chase prey on marshy ground. At the animal there is short tail with hairy brush of lengthened hair on the tip.
At marafil there is short head with powerful high jaws. Canines are rather short; molars and premolars of animal work as crushing tool – marafil female can shatter the backbone of rhinoceros-sized prey by one bite.
The skin of marafil female is covered with rough short wool of brown color. There are vertical strips of black color on shoulders and sides and some black spots on hips (sometimes they may be absent). Wool on head of animal is black, but around of mouth there is a strip of white wool – this attribute has the important value at the communication of animals. Marafils, especially females of this species, are rather aggressive animals, and in many cases it is vital for them to be able to distinguish mood of the congener from afar to behave in appropriate way.
Very sharp sexual dimorphism is characteristic for marafils. It is shown not only in difference of body sizes, but even in colouring. Skin of marafil male is grey with numerous black spots merging on shoulders to vertical strips. On the neck of male there is a mane of long grey hair. Males look more harmonous and long-legged, rather than females and can run much faster. Also at the male there is longer and narrow muzzle with more advanced canines which partly jut out from closed mouth.
Males live and hunt in packs of ten individuals, living mainly at the boundary of territories of female clans. They do not make constant refuges, and spend the night in the same place no more than two nights in succession. Females of marafils, on the contrary, make constant lairs in bush and come back there every day. They lodge in clans of 4 – 5 individuals connected by consanguinty (as a rule, it is the female and her senior daughters). The number of marafil males in population is smaller, than the number of females: it is connected with the high mortality level of these animals at young age. When young marafils grow up, young females dominate over males compelled to be content with the rests of their catch. When the young marafil male reaches about one-year-old age, it is expelled from clan, and some time it leads single life, eating the scraps had remained after hunting of parental clan. Groups of marafil males can unite, forming male packs.
Sexual dimorphism of marafils is shown also in hunting preferences: there are different catch and different hunting tactics at males and females. Females chase mainly sluggish catch – huge bullhogs. Males prefer to hunt swift-footed hoofed mammals, badgering them by pack like wolves. Hunting habits at different genders also differ – females hunt at night, attacking resting and feeding animals, and use during hunting sharp sense of smell. Males hunt in day time with the help of sight.
Marafil females being in group are very aggressive to neighbours. It happens they can attack males of their own species, kill and eat them as if other prey. Therefore pairing at marafils occurs outside of territory of female clan. For pairing males mark with urine objects well appreciable from afar (for example, lonely growing tree, large stone or termitary) at the edge of territory of females, and wait for female near this place. Thus they drive other males off from the marked sign. Also males leave some of labels at the territory where the female clan lives. Usually they do at the afternoon before females will leave on hunting. But at the same time males try to keep together and to be on alert. They succeed to have a sleep only in second half of night and in the morning approximately till midday when females come back home from hunting. The female ready to pairing leaves clan, finds the site marked by males, and males pair with it by turns. Before pairing the female shows absence of aggression to males: she lowers head and presses ears. Males showing the superiority run near her by whole pack with lifted heads and occasionally bite the female to shoulders and groats.
Similarly to all large animals, marafils breed seldom: each female gives rise to posterity alternate years. Pregnancy lasts about half-year, and cubs are born to the beginning of rain season. They suck milk till four – five months, but start to try meat food at the third month of life. In litter at one marafil female it happens three – four cubs. Usually only half of posterity survives up to independence.
Young females become able to breeding at the age of 4 years, and males since 3 years. Life expectancy at females of this species reaches 50 years and more, and males seldom live up to 40 years.

Qualmi (Geolynx americanus)
Order: Carnivores (Carnivora)
Family: Cats (Felidae)

Habitats: woodlands and the central part of the Great Plains of North America.

Picture by Wovoka

Lynxes suffered from anthropogenic pressure less compared to other large felines. During the human epoch, their population declined, and they failed to fully restore their former range. Viable populations remained only in a few places in Eurasia and North America, and throughout their subsequent history lynxes had to compete with the descendants of smaller cats, including with hybrids of domestic cats and wild species. In the forests of Siberia and North America, the descendants of lynxes are saber-toothed predators, megafauna hunters, a peculiar way of avoiding competition with other cats. In addition to them, other descendants of lynxes live in North America, being less specialized ground-dwelling predators. To the south of missopeho range, a descendant of the bobcat (Lynx rufus) – qualmi (the name means a shapeshifting lynx from Canada) – lives.
The range of qualmi is limited by plains and sparse forests in the central part of the continent, in the area of seasonal climate. The distribution to the south is limited by competition with balam; in the north the range of this species borders on the missopeho range, and in the west – with silver nev, a puma descendant. The competitor of this species is lupardus, a cursorial canid species, but these species differ in the size category of preferred prey: qualmi hunts larger prey.
Qualmi is a predator of relatively light build: body length is 100-130 cm, height is 60-70 cm at the withers, and weight does not exceed 50 kg. Wool coloration is reddish-gray with large dark spots forming several longitudinal rows on the sides. Tail is short, which makes it difficult for the animal to change direction when running, but this is compensated by endurance: qualmi can chase the chosen prey for about 10-15 minutes, not allowing it to stop and rest. It feeds on medium-sized animals ranging from hares and rabbits to deermaras, young asinohippuses and rapidocervus deer. Most often, this predator attacks prey from an ambush among bushes or in tall grass, although if necessary, qualmi can sneak up on prey literally on its belly, hiding in low grass. Its claws are not retractable, providing good grip on the ground when running.
Qualmi is a solitary territorial animal, with only females hunting with their cubs for a while. Qualmi is usually uncommunicative; the predator’s voice can be heard quite rarely: males growl when fighting for the territory, or roar and howl in a deep voice, competing for a female. The female also communicates with her cubs with the help of sounds. Males’ battles for territory are usually ritualized and include growls, bristling fur on the back of their necks and clawing at the grass.
The mating season is in early spring, and the birth of offspring occurs in the first half of summer. Males search for females by marks with a specific scent, and when rivals meet near a female, fights between them are more violent than over territory, and often end in scars and lacerated ears. The female makes a den among the bushes for her offspring. Kittens are born after 70 days of pregnancy, and there are usually 2-3 blind cubs in the brood; the eyes open on day 12. At the age of one month, the mother begins to feed the kittens with solid food, bringing them dead prey. Grown-up cubs hunt with their mother during their first winter, until the next breeding season. Usually, the young are driven away from the female by adult males, or by female herself, when she feels the onset of pregnancy. Females reach sexual maturity at 21 months, and males at 33 months. Life expectancy is 15-20 years.

Awful daggerclawer (Pugionyx deimus)
Order: Carnivores (Carnivora)
Family: Cats (Felidae)

Habitat: Eastern Asia, Far East (area of moderate and subtropical climate), flatland woods, foothills.

Picture by Sauron from FurNation

In Holocene the cats family has suffered the big damage from human activity. Number of large cats was sharply reduced, and their areas have catastrophically decreased. Small cats have suffered from hunting for the sake of valuable fur. The unique representative of family has received the big advantages in a survival in human epoch is the domestic cat Felis catus. Due to people this predator was settled practically in whole world. It became a stimul for evolution of the present species. As against the majority of domestic animals dependent on people, the domestic cat easily runs wild. Therefore after disappearance of people this species have not died out in common with them, and have continued to exist. The majority of Neocene felines descend from several species of rather small cats have survived hunting and ecological crisis.
Cats are successful predators; therefore descendants of domestic cats have taken the high place appropriate to their abilities in food pyramids of new biosphere. And in Neocene among them large animals from the number of the most terrible land predators of Earth have appeared. One of them is the awful daggerclawer, specialized large prey hunter.
It is very large cat: it is lion-sized, but it seems larger because of longer legs. At daggerclawers characteristic features of appearance, common for cats, were kept: rather short jaws, large canines, binocular sight. Daggerclawers are solitary animals.
The body of daggerclawers (in the Neocene world there are few species of these cats) is covered with fluffy wool. At the awful daggerclawer the colour of wool is similar to “tortoise-shell” color of some domestic cats - on grey background there are big, almost symmetric dark spots. Tail of animal is long, on it spots merge to non-uniform cross strips. A tip of tail of animal is white. White sites are on the bottom part of muzzle; throat and breast are also white. On hinder legs of animals of this species occasionally there are white “stockings”. Forepaws of daggerclawers are colored contrastly and brightly: from an elbow up to fingers they are covered with alternating wide black and white strips. This colouring is the important element in behaviour of animals as it is used in rituals of an establishment of domination. It is shown only at adult animal of both sexes. Not sexual matured animals have dark forepaws.
At capture of catch cats actively use forepaws. And this feature of behaviour has received development at the present species and has reached high specialization. On paws of cats there are five fingers from which four ones base on the ground, and the first, the shortest one, does not touch ground. At daggerclawers on first fingers of forepaws crescent claws of huge size (its length is up to 20 cm) were developed. In rest this claw is pressed to the paw and its end is directed back, not preventing walking and running. On the internal sides of wrists of the animal there are sites of very thick cornificate skin, and this claw adjoins directly to this one. Also this claw is partly retracted in skin cover. The “fighting” claw of the daggerclawer is partly similar to claws of small predatory dinosaurs like Deinonychus and Velociraptor.
The daggerclawer eats large ground animals. Attacking prey, it at first creeps to it to probably closer distance, and then rushes to the planned victim. Due to long legs it can accelerate momentum up to 60 kms per hour on the short distance. At the moment of solving jump the animal shows its “fighting” claws, and puts to the victim deep wounds by them. When impact has falled on the neck, catch of the daggerclawer, even having escaped from its claws, quickly bleeds profusely and perishes. In case of successful attack the daggerclawer, except for impact by claws, delivers to prey sting in neck or in the basis of skull: this is the “inheritance” stayed from its ancestor, the domestic cat.
All daggerclawers are solitary territorial animals. Usually at them as at tigers, the territory of the male includes territories of several females. Animals mark territory, fleecing bark from trees, and rubring the bared wood with a secret of chin repugnatorial glands. Males also mark the territory by urine. During an establishment of domination relations animals pay special attention to colouring of forepaws of the contender: the more contrast coloring, the animal having it is stronger. At young animal paws are dark; at old ones they are “gray-haired”: strips become not so contrast. Duels for territory and place in hierarchy, as a rule, are limited by demonstration of “stretching” of contenders: thus animals by turns bend backs and extend forward forepaws, showing their colouring. “Stretching”, each animal tears off by claws a part of grass, breaking through deep furrow by “fighting” claw. Such ritual behaviour helps to avoid fight, and contenders can estimate force each other. It is accompanied by loud mewing and squeal.
Pairing occurs in middle of winter, kittens (2 - 4) are born in first half of spring. They are covered with dark wool, blind and deaf. The female feeds with them with milk about four months, and then even more half-year young animals keep with mother. They abandon her in winter, and more often they are banished by males during a rut.
Sexual maturity comes approximately at three-year age. At this time at males strips on forepaws start to appear. But most successfully males are coupled approximately since the fifth year of life: females give obvious preference to males with striped forepaws.
Life expectancy of the awful daggerclawer reaches 30 years.
There are some other species of daggerclawers distinguished in smaller size in East Asia in moderate and subtropical latitudes:
Fisher daggerclawer (Pugionyx piscivorus) is a predator up to half meter at a shoulder. Length of its body is about one meter; a tail is about 60 cm. The head is dark with white area on the tip of muzzle and throat, above eyes there are white spots; wool has striped colouring. Forepaws up to an elbow are white, occasionally on them there are one - two cross strips. The claw is rather larger, than at the awful daggerclawer: its length is about 15 cm. In rest it is strongly unbend back, resembling cock heel.
The animal inhabits marshlands, riverbanks and lakes. The fisher daggerclawer willingly swims and prefers to not leave water far. The animal eats fish and aquatic animals: turtles, frogs, waterfowl and rodents.
Bird-catching daggerclawer (P. saltatus) is the smallst species of genus (length of body not including tail is about 60 cm; tail is about half meter long). It is settled more widely than other species: this cat inhabits areas from plains up to mountain woods. It also differs in especial addition: hinder legs are strong, appreciably longer than forepaws (back is inclined forward). Colouring of wool is spotty: on background from sand up to red there are dark brown spots. Forepaws armed with sharp crescent claws are colored black with white spots. This animal eats mainly birds. It dexterously forces down flying up birds, killing for one jump up to five ones from flight. It eats catch, keeping it in forepaws and sitting on back legs (by same habits Holocene caracal (Felis caracal) had differed).

The idea of the present animals is prompted by Simon, the participant of forum.

Among pets only few species had gone through disappearance of mankind. Selecting breeds of various domestic animals, people had changed their physiology and behaviour so deep, that many breeds appeared as a result of domestication were completely unable to exist independently. But nevertheless there were the exceptions – primitive breeds of domestic animals ran wild easily. Also the process of adaptation to wild life passed successfully in conditions of isolation and absence of predators – strange sheep descendants in New Zealand have appeared this way. But domestic cat (Felis cattus) appeared the champion in adaptation to life in a nature, and people did not manage to subordinate it to their will completely. Descendants of domestic cats live on various continents and islands. At the territory of Central and Eastern Asia extensive mountain areas are inhabited by one of such species – menkw*, the universal predator, the expert in survival in mountain forests.
In its ecology menkw is the analogue of leopard, but in shape it resembles lion a little. The basic colouring of this animal is brown with a pattern of spots and cross strips on paws and tail. The wool on trunk is almost monophonic, pattern of vertical strips is present only at kittens to the age of about one year, and completely vanishes during an autumn fall-off. Male of this species is larger than female and has short small mane covering nape, neck and forward part of breast. In autumn animals change wool to winter fur, longer and lighter in color.
The length of menkw body from head up to a tail is about 140 cm; tail is 90 – 100 cm long. Weight of adult individual may reach 75 kg, mature males frequently weigh over 80 kg. This predator hunts any animals it can catch, from a rat up to boar in size. This animal usually hunts from an ambush, suiting it near tracks of herbivores in bushes or behind the fallen tree. This predator frequently jumps on prey from tree, choosing for ambush thick branch among foliage. This predator kills prey by strong bite in throat, simultaneously throttling it and biting through blood vessels of neck by canines.
This species is territorial; adult male occupies territory measuring over 60 square kilometers. In male territory up to 5 females – its harem – and posterity up to one and half years old live. Each morning male declares its rights to the territory with loud call. It has no constant shelter and within several days walks riond its territory, renewing border marks. For this purpose it tears bark on trees and also waters it with urine. Nevertheless, these animals are rather tolerant to each other: the meeting of two males out of breeding season is usually finished only in force demonstrations. Males rear wool and yell loudly, trying to impress the opponent, but enter fight seldom.
Pairing at menkw takes place in winter or in early spring. At this time boundary skirmishes between males become more often and the number of fights grows. They frequently come to an end with ragged ears and scars on shoulders. In especially severe duels one of males can even receive fatal traumas. Pregnancy of female lasts till 90 – 100 days; usually 3 – 4 kittens are born. For delivery female chooses reliable shelter, as a rule, a tree trunk rotten out from within or a cave. She feeds cubs with milk within 2 months. Kittens are born blind and open eyes at the age of 3 weeks. The young growth of this species differs from adult individuals with visible vertical strips on sides which vanish with the years. They are independent at the age of 5 months and reach sexual maturity at two-year-old age. With approach of this age females join the next groups of menkws, and males should win territory and females to themselves, or wander on boundary territories of stronger males. Life expectancy is about 35 years.


* Menkw is a forest goblin in mythology of Siberian folks.

Tiger neosmilus (Neosmilus tigrinus)
Order: Carnivores (Carnivora)
Family: Cats (Felidae)

Habitat: forests of Southeast Asia and Jakarta Coast.
In the human epoch, predatory mammals suffered great damage. Hunting and habitat destruction have destroyed almost all species of large predators, as well as a number of relatively rare and local small species. After the human disappearance, this circumstance opened the way for more widespread small predators, one of which turned out to be the domestic cat (Felis cattus). In Asia, its descendants are the formidable predatory daggerclawers (Pugionyx). And to the southeast of them, neosmilus, another species of large cats, lives.
Body length of an adult animal is 160-170 cm, tail length is 70 cm, the height at the withers is 70-75 cm, and the weight is 65-70 kg. Wool coloration varies from light yellow to reddish yellow with a pattern of spots and transverse stripes on the paws and tail. There is a dark “mask” on the animal’s face. The front paws of the beast are very powerful: they allow it to hold large prey like thunderhorns, pigs and monkeys. Teeth of neosmilus are unusual in their structure – large canines are located in the powerful lower jaw, and there are only two lower incisors. In this feature, it resembles a Pleistocene marsupial lion. Masticatory muscles are large, and there is a sagittal crest on the skull, which makes the back of the animal’s head look a little like the back of gorilla’s head. During the predator’s attack, a blow of its lower canines damages the prey’s arteries – but after feeding of neosmilus, a lot of meat remains on the carcass, since the beast is poorly adapted to gnawing meat from bones. It is a heavy, slow-moving predator that ambushes prey. The legs of neosmilus are relatively short and it cannot chase prey for long.
The mating season takes place from December to January. Males find a female by scent and follow her until estrus begins. When two males meet, fights often break out, accompanied by roaring. The animals fight each other like bears, striking the shoulders and head of the opponent with their front paws.
The rate of reproduction is relatively slow. Pregnancy lasts 3 months, and 2-3 kittens are born. For delivery, the female hides in mountainous terrain, preferring to settle in inaccessible caves. The young develop slowly. At the age of 3 weeks, kittens begin to see, and two-month-old cubs begin to taste meat. At the age of 10 months, young animals are already hunting with their mother and are learning hunting techniques and interacting with their relatives. At the age of 2 years, they turn independent, and the female is ready for a new mating. A year later, neosmilus reaches sexual maturity, but males participate in reproduction only from the age of 5 years due to competition with older congeners. Life expectancy is up to 40 years.
Sunda Land and Kalimantan harbor some closely related species.
Smoky neosmilus (Neosmilus fumosus) is a smaller predator of slender build, 95-105 cm long, grayish-red with striped legs. It feeds on running herbivores and can chase prey for a while, trying to knock it down with its paws. The habitat of this species is the forests of Sunda Land.
Kalimantan neosmilus (Neosmilus borneensis) is also smaller than the mainland species, with a body length of 85-95 cm. Its coloration is very characteristic – large black spots of irregular shape on a yellow background. It is a species that leads a more arboreal lifestyle in the rainforests of Kalimantan. It is found in areas of disturbed forest and often stalks prey from tree branches or large rocks.

Felimalagasia (Felimalagasia gracilissima)
Order: Carnivores (Carnivora)
Family: Felids (Felidae)
Habitat: Madagascar, various types of forests.

Picture by Amplion

When humans appeared on the Madagascar, they heavily damaged if not outright destroyed the unique ecosystem of the island. The large animals became extinct due to the hunting and deforestation. Destroying of natural habitants at the end of the mankind era led to the extinction of fossa (Cryptoprocta ferox), the largest predator of the island. The smaller viverrids survived but they have become mostly land-based predators or small climbing animals. The ecological niche of large climbing predator was given to another animal descending from domestic cat. It has developed a set of adaptation to hunt fast-climbing and careful prey and has become a beast who looks much like a huge marten. It’s felimalgasia, the domineering predator of forest canopy occupying the top of food chain.
Felimalgasia spends almost all the time in the trees but sometimes gets down to the earth during the hunt. The build of the animal is adopted for fast movement in forest canopy. The legs of felimalgasia are relatively shorter than those of cats, the body is longer- the height of animal is only 50 cm while the length is up to 150 cm without the tail. The spine is incredibly flexible- the long neck permits to turn the head around on 180°, and before the jump the animal can fold itself in two. The long tail serves as balancing pole during the jumps, the movements of tail provide necessary balance.
Small head with short stout is inherited from domestic cats. The ears are relatively wide, with rounded tips: the hearing of felimalgasia is very acute. The eyes in the front of head provide stereoscopic eyesight which is really important for tree-climbers. The mouth opens wide. The animal uses its columnar teeth to kill birds with relatively fragile bones, biting them through the spine or the base of scull. Big animals such as lemurs are killed with bites in the tissue of the neck while being held in place with paws. Felimalgasia has relatively good sense of smell, well-developed whiskers help the animal to orient in forest canopy even in the dark.
The colour of fur serves camouflaging purposes. The main colour is a shade of yellow, it’s covered with multiple wide spots, forming long lengthwise stripes on head and neck. The pattern of spots is individual. On the tail stripes form rings and the main colour changes from yellow to white. With the stripy end of the tail felimalgasia sends visual signals to the others of her species, but that animal being solitary rarely has need for communication save for the mating season.
The usual prey of felimalagasia is lemurs and birds; though sometimes it’s smaller animals such as frogs, lizards and even small insects.
The animal tags its territory by tearing the rind of the trees with its claws. The territory of each adult animal is about 30 square cm. Only during the heat the female tags the territory with urine which has specific smell during that period. Felimalgasia rarely climbs down from the trees so the animal doesn’t dig its feces, but urinates and defecates from the trees and feces fall down to the ground. Because of that the inhabitants of forest canopy can’t detect its presence, and hunt in the underbush happens relatively rarely.
The litter of female happens once in a year and includes up to 5 kittens, but only two or three of them reach maturity. The female makes its den in relatively large hollow or usurps big bird nest (for example the one of false macaws) which is adopted to suit its basic needs. The kittens are different from adults in colour, the dark spots on their fur are relatively bigger. The kittens stay with their mother till they’re 5 month old – usually by that time female has already mated with another male and is pregnant again. The maturity is reached at the age of 2 years; the life span of felimalgasia is up to 20 years.

Reunion nanoleo (Nanoleo insularis)
Order: Carnivores (Carnivora)
Family: Cats (Felidae)

Habitat: Reunion Island, forests of the central part of the island.

Picture by Pavel Volkov (typical version of coloration)

After the human disappearance, domestic cats (Felis cattus) turned out to be very widespread animals – they were found in various parts of the Earth, where they could not get in natural way, including on isolated oceanic islands. Many domestic breeds became extinct, being unsuitable for life in the wild, but mongrel populations easily ran wild, being mixed then with residual populations of small wild cats, giving rise to new species. When many large felines disappeared completely, the descendants of domestic cats easily occupied vacant niches, competing with predators of other families. In the historical epoch, cats had been introduced to Mascarene Islands. In Neocene, they persisted on the islands, but failed to grow up there due to the limited territory of the island. However, the prey has become smaller in size, and small felines have become formidable predators of the islands in their weight class. Maurosmilus lives in Mauritius, and Reunion nanoleo lives in neighboring Reunion, displaying a different way of adapting to the island environment.
The body length of this animal is about 58 cm, with weight of 4.5-6 kg. The coloration of the thick short wool is reddish-gray with dark spots. This species has an expressed sexual dimorphism – a thick mane grows on the male’s head, giving it a resemblance to a lion. Another similarity is behavior: nanoleos live and hunt in families of 4-5 individuals – a couple and their offspring. Each group occupies a certain territory in the wooded part of the island, avoiding appearing on the sea coast. Males resolve border conflicts by growling and displaying, fluffing their manes to look bigger. In strong males, the mane covers the back of the neck and stretches over the shoulders, becoming an additional protection during predators’ conflicts.
The largest mammals of the island, the dwarf descendants of pigs and goats, become the prey of this cat. It attacks tenrecs less often – they are not very tasty, and swimming tenrec can inflict wounds. Pointed retractable claws grow on the paws of nanoleo, and there is a pair of powerful cutting teeth on the lower jaw. And if it strikes the goats with its claws, then it bites the pigs in the throat and strangles them, cutting at the same time the soft tissues of the neck.

Picture by Cossus (melanistic version of coloration)

Due to the limited area of its habitat, the rate of its reproduction is slow: nanoleo reproduces once a year. Rut takes place in August-September, pregnancy lasts 60 days. There are 3-4 kittens with dark fur in the litter. Only the main female of the group participates in reproduction. For the first 2 weeks, while the kittens are blind and helpless, the mother does not leave them, and her family feeds her. At the age of one month, kittens begin to taste meat, at 2 months they try to hunt, and at 8 months they are already independent. Young males leave their families and gain experience on their own. Many of them die at this time in skirmishes over territory or during unsuccessful hunting. Females stay in their family until puberty, which occurs at the age of 18-20 months. When they grow up, they move to other families or are taken away by young males, in which case they are more likely to stay alive. The older family females do not always accept the young ones; conflicts arise between them and some of the young females die from wounds. The male does not interfere in fights between females. Life expectancy is 12-14 years.

Pitua (Insulocattus mustelops)
Order: Carnivores (Carnivora)
Family: Cats (Felidae)

Habitat: Marquesas Islands, forests.

Pictures by Pavel Volkov

By the beginning of Neocene, felines had suffered quite a lot from changes in the biosphere of the Earth. Large species that could not withstand hunting and habitat destruction became almost completely extinct shortly after humans – only in South America and East Africa did relict populations survive, giving rise to new species. Small cats and lynxes were more fortunate; some species, whose numbers were undermined, disappeared, but the rest ones occupied the maximum ecological niches available for cats. Domestic cats were especially lucky in this sense – humans settled them in many areas of the Earth, and their descendants have been preserved in many habitats, up to oceanic islands. One of their island descendants is pitua.
This cat species resembles a marten in appearance – it has relatively short legs, a flexible spine, an elongated body and tail. The body length is about 60 cm, the tail is 25 cm, and the weight is 5-6 kg. The animal is good at climbing trees, moving on the ground and can swim, if necessary. The animal has a relatively large head and movable rounded ears with large auricles, which makes the animal’s head look a bit like a bat’s head. The wool coloration is cryptic: large, irregularly shaped black spots are scattered on a yellowish background; their size and pattern vary among populations on different islands. The forms from Fatu-Hiva and Hiva-Oa have a black stripe on the back, and the spots are located more thickly. Dwarf forms with a body weight of no more than 2 kg are found on small islands. Sexual dimorphism is not pronounced.
Pitua is a solitary animal and usually keeps in thickets; it is good tree climber and spends a lot of time on tree branches. The animal feeds on rodents, bats, birds and reptiles. Pitua is one of the top predators of the archipelago (hence the name meaning demon of Polynesian mythology).
These cats do not have pronounced mating periods; males identify a female ready for mating by scent and gather on her territory. Pregnancy lasts for 84 days, and only one or two cubs are born. They are colored gray and have black spots already at birth. At the age of 10 days, kittens open eyes, and at the age of one month they go hunting with their mother. At 5 months of age, young animals are already independent and reclaim their own territory – at this time, a significant number of young animals die. Cannibalism in relation to young animals is quite common among adult animals – this is a kind of way to prevent population growth. Puberty occurs at the age of 2 years, and life expectancy is up to 18 years.

Ngeru hou (Australofelis postdomesticus)
Order: Carnivores (Carnivora)
Family: Cats (Felidae)

Habitat: New Zealand, North and South Island, forests, woods, bushland, mountain forests.
Initially, introduced domestic cats became a feral pest in New Zealand and caused many problems for native wildlife, especially birds and reptiles, but this creature became a lesser player in the long term. Equally pugnacious and more adaptable feral Possum (Trichosurus vulpecula), increased in size and became the dominant predator of Aotearoa, Marsupial Pardus.
Feral cats instead formed an analogy of their ancestor, Felis sylvestris, becoming the Ngeru-hou (“new-cat” in Maori). General appearance recalls a Wildcat or a large tabby. Body is up to 60 centimetres long, with a tail up to 20 centimetres long, relative shortness of tail is retained from domestic ancestor. Legs are a little longer than that of a domestic cat, and skull is a little longer and more robust. Coloration is a spotted tabby pattern on a light brown background, with a dark ringed tail. Coat is shorter and paler, and animal is overall thinner, in the sub-tropical parts of its range.
As with most wildcats, it is solitary, though it will sometimes tolerate others of its own kind, as with its domestic ancestor. Diet consists of prey caught from ambush, small and mid-sized birds, rodents, rabbits and reptiles, as well as large insects such as moths. This cat is most active by night, and retreats to sleep in secluded places by day. Vocalisations generally recall that of its ancestor, yowls, hisses, mewling and meowing, but is somewhat louder and more eager in tone.
Sexual maturity is reached at 10 months, female has one oestrous in March or April, and gestation is up to 65 days. Mating and contests for mating result in loud yowls and screams. Litter sizes vary from 3 to 8 kittens, which are suckled in a den, usually under a bush, rock outcrop or tree roots. Kittens learn to hunt at 10 to 12 weeks and are fully weaned by 14 weeks. They leave their mothers at about 6 or 7 months but may remain in her territory a little longer. Lifespan is generally up to 15 years but can be longer.

Island Tigrillo (Arbofelis pseudotigrillo)
Order: Carnivores (Carnivora)
Family: Felids (Felidae)

Habitat: Galapagos Islands, main large island, forest.
Among the animals introduced to the Galapagos Islands was the Domestic Cat (Felis catus), which has left some successful descendants here in the Neocene.
Island Tigrillo gets its name for its small size and the resemblance of its coat to a Holocene kind of cat, the Margay (Leopardus wiedii). However, build of this animal is different, legs are shorter and more flexed at the knee and body is longer, almost resembling a Marten. Animal weighs about 2.5 kilograms and body may be up to 45 centimetres long, tail about 40 centimetres long. This cat spends most of its life in the branches and tops of trees; prey includes birds, lizards and tree-climbing rodents as well as large insects. The spine is very flexible and legs are bent, allowing the animal to make prodigious leaps from tree to tree. Head is longer and more muscled than its ancestor, canine teeth are slightly longer proportionally. Ears are large and rounded, bearing fur on the outside, facial whiskers are well developed. Coat is yellowish in colour with a pattern of spots serving as camouflage, resembling a leopard or its namesake the Margay, tail is banded in black and yellow.
This animal is mainly nocturnal but may hunt in late afternoon and early morning. They are solitary and maintain distinct territories; individuals will yowl loudly to proclaim their territory. Animal marks boundaries with urine and does not leave the trees to defecate.
Breeding occurs once a year, litters consist of up to 6 kittens, which are reared in a tree hole lined with leaves. Kittens initially have eyes closed and are darker than their mother in colour, but still bear the beginnings of spots. Kittens remain with the mother for 3 and a half months, sexual maturity is reached at 5 months old, individuals may have a lifespan of up to 10 years but usually much less.

Galapagos Nano-Otorongo (Tigrefelis ferox)
Order: Carnivores (Carnivora)
Family: Felids (Felidae)

Habitat: Galapagos Islands main large island, open habitats, scrub, woods, ground dwelling predator.

Picture by Pavel Volkov

It has occurred many times in the Neocene that introduced invasive predators have produced apex predators in their new domain, and so we see with Domestic Cats (Felis catus) in the Galapagos.
Apex predator of the here is the Galapagos Nano-Otorongo, a formidably built small cat which may reach up to 12 kilograms, name refers to Otorongo, Peruvian word for Jaguar. Animal generally resembles a large, short-haired domestic cat; body may be up to 60 centimetres long, with tail about 50 centimetres. Animal differs in shape noticeably by more muscular build, larger head and prominent canine teeth. Canines of this cat are long both on the top and bottom jaws, resembling those of the Clouded Leopard of Holocene (Neofelis). Such weaponry is connected to the diet of this animal; it hunts the larger animals inhabiting the island, including pigs, iguanas and big rodents. Colouring of this animal is a typical “tabby” pattern, but somewhat less distinct than in a domestic cat, background of fur is light brown and spots are a darker brown.
Animal is diurnal but may hunt in twilight or at night occasionally, these cats are solitary, forming distinct territories which are proclaimed with loud screeching yowls, and marked with urine. Other calls include a deep mewling sound or a hiss when angry. This cat mainly hunts from ambush, hiding amongst vegetation in order to chase and pounce at relatively close range. Prey is killed with a throttling bite to the throat, or puncturing of the jugular vein.
Breeding occurs once a year, during the wet season, oestrus of the female lasts up to 8 days. The female makes a den that is a scrape hidden in a covered area of undergrowth or bushes, and gives birth to up to 5 kittens. Kittens stay with mother for about 4 months; sexual maturity is reached at about 6 months. Lifespan may be up to 15 years, but usually much shorter.

Gatito (Nanofelis musteloides)
Order: Carnivores (Carnivora)
Family: Felids (Felidae)

Habitat: main island of Fernando de Noronha Archipelago.

Picture by Wovoka

During the Holocene, humans had caused several impacts on the environment. Among their actions was the introduction of exotic species and the places that most suffered with it were the islands. With the disappearance of the human species, these animals remained and some evolved in new species during the Neocene. One of these cases was the gatito, a descendant of the domestic cats that were left in Fernando de Noronha after the disappearance of the humans. The word gatito means kitten in Spanish and can also be used informally in Portuguese to name the same thing. This species is the only representative of the Genus Nanofelis and is endemic to the largest island of the Archipelago.
The gatito is one of the smallest felines of the Neocene, with the males having a body length of 30 cm, while females have 26 cm. The tail is 8 cm short in males, while in females it's 6 cm. They have a slim and flexible body with short limbs, which gives them the appearance of a weasel. Their fur is reddish-brown and entirely covered with black spots, while their tail is black with faint brown-colored rings.
This species eats insects, lizards and small birds. However, their main prey is the Noronha rat. The gatito developed such a slim body exactly to hunt this rodent. Using their flexibility, these small felines are capable of invading the dens made by the rats, killing them while they are resting. Such dens are occupied and enlarged by the felines, which turn them on their home. While they can be active at any hour of the day, gatitos prefer to hunt during the night. This occurs not only because the Noronha rat is mostly a nocturnal animal, but also because they want to avoid predation by the long-legged hawk and raptorial gulls.
The gatito is solitary, with males and females meeting only when mating, which can occur at any time of the year. The female have a 37 day gestation period. During this period she prepares her den to give birth by feeling it with grass and leaves. She raises its kittens without help from the male. The newborn are born pink, naked, blind and deaf, but gain a brownish coat of downy fur at the age of 4 days. At 10 days, the fur starts to become reddish-brown and the spots start to appear. The milk teeth erupt at 2 to 3 weeks of age, at which point the young start to eat solid food, though lactation can last 12 weeks. The eyes and ears open at 3 to 4 weeks of age, and by 8 weeks, killing behaviour is developed. The family breaks up after 9 to 12 weeks. They reach sexual maturity with 4 months and can live for 8 years.

Tiger raptor cat (Felinoraptor tigrinus)
Order: Carnivores (Carnivora)
Family: Felids (Felidae)

Habitat: South America, subtropical and temperate areas; light forests and woods in foothills.

Picture by Amplion

At the boundary of Holocene and Neocene human activity had caused the mass extinction of large herbivores. It had resulted in extinction of set of predators, including large cats of genera Panthera (the majority of large cats), Uncia (snow leopard), Acinonyx (cheetah). In same time many smaller cats became the extremely rare as a result of hunting or destruction of natural environment. However, the felid family had survived in Neocene. But in most cases it is the consequence of worldwide settling of domestic cats which descendants had run wild and had taken part in formation of new ecosystems in various parts of the world.
In Neocene connection of South America with other continents had interrupted again. Some time in early Neocene the Antilles land bridge existed, and using it land animals could settle, but then it had disappeared. In conditions of isolation descendants of puma (Felis concolor) had turned to very large predators of frightening appearance. These cats of South America represent the unite group which has the general distinctive attribute – the original adaptation for killing of large prey. The inner toe on hind leg of these cats had strongly changed: it became little bit shorter than the others, but on it the huge strong claw is developed. In rest it is retracted into special sac formed by skin plica. When these cats attack prey, they seize it by forepaws and tear prey’s flesh between ribs or on the stomach by “battle” claw of rear legs. This adaptation resembles very much the feature of hind legs anatomy of small theropod dinosaurs of Cretaceous, and hence the name of such predators – raptor cats. It is the original experiment of evolution: in South America the kind of contrast to Asian daggerclawers, massive cats with similar “battle” claw developed on forepaw had evolved.
The constitution of these predators is rather light and “universal”, permitting them to swarm up trees and to move on rocks good. Due to this feature raptor cats are widely settled in South America in places where enough plenty of large herbivores lives. They are the specialized hunters on large sluggish prey - large rodents barocavia and giant paca. Occasionally they attack on young tapirotheres and groundsloth rodents. These cats attack prey from an ambush, strike it a blow by “battle” claws, and jump off aside. If the animal had not died from the first attack, the cat pursues prey, not repeating attack while the victim will die from loss of blood.
In South America three well differing species of these large cats live. Largest of them is tiger raptor cat – the lion-sized predator. This species has dark-rusty skin with numerous vertical strips of black color on body and paws. Ears and top part of head of this cat are black, and cheeks and throat are white. Tiger raptor cat inhabits flat districts and foothills, preferring the mosaic landscape where areas of grasslands, woods and rivers are combined. It is a solitary predator; each individual occupies extensive territory up to 30 square kilometers in area. Despite of large size, tiger raptor cat is freely able to swarm up trees and rocks and also to swim. It easily attacks prey in water, and its prey may often become barocavia or giant paca – semi-aquatic rodents. Occasionally these cats catch young thyranncharaxes - huge predatory characid fishes.
This species of cats marks borders of territory by urine, leaving it on bushes, tree trunks and termitaries. The territory of the male substantially overlaps territories of several females living in the neighbourhood. Usually females concern tolerantly enough to the presence of male out of breeding season, though the female with cubs or near the prey can be aggressive to him. Males concern to each other much more aggressively, and at the meeting necessarily display the force to each other. This demonstration of force at well armed predators passes very originally, practically without the direct contact: they sort out their relationships in original competition, by turns or nearly so simultaneously jumping on tree trunk. Having seized claws in bark, males hang on a trunk till some seconds, hissing against each other, and then jump off. Usually the winner is the one jumping higher and keeping on tree for longer time. If males are equal in force, they can combat. Also the adult male concerns aggressively to male youngsters; the majority of them perish till first months of independent life from paws of adult males. In rare cases the old male can become cannibal and steal cubs at females living in the neighbourhood.
Courting the female, the male leaves marks in her territory to give the female the opportunity to get accustom gradually to his presence. “Unready” female can rush on the male if he will appear too suddenly – usually it happens so at young males. The female is ready to pairing till several days, and all this time the male preserves her against other males, and frequently pairs with her. When the rut stops, female banishes the male, showing aggression to him.
After six-monthly pregnancy, in the beginning of rain season female gives rise to the litter of from two to eight cubs. In big litter usually only three or four cubs have an opportunity to grow up to independence. For rearing of posterity the female arranges the den in bush or in wide hole dug out additionally to the necessary size. Cubs are born blind and deaf. Their wool has the same strips as at adult individuals, but strips are rather wide; therefore cubs seem darker, than adult individuals. At three-monthly age they leave a den and start to study to hunt actively. Young animals spend with mother about one and a half years, therefore the female brings posterity only once in two years. Young animals become sexually mature at the age of three years.
The close species lives in mountains of South America: the Andean raptor cat (Felinoraptor andinus). It is little bit lower growth, than tiger raptor cat, but is built much stronger and heavier than it. The “battle” claw on hind legs at this species is advanced not so extremely – in mountains there is less number of large prey, and Andean raptor cat eats mostly smaller animals – birds and rodents. But it also hunts young mountain tapirotheres.

One more species, the Chilean, or western raptor cat (Felinoraptor occidentalis), lives in narrow land strip between Andes and Pacific coast of South America. It is settled from equatorial latitudes up to Tierra del Fuego. This species of cats differs in pale yellow skin with some dark spots. Northern populations living in warm latitudes have more gracile constitution and wider ears, and southern ones, living in areas of cool climate, are smaller and short-legged, with almost one-colour rich fur. In the extreme south of South America this species of cats is superseded by larger Andean raptor cat. Chilean raptor cat almost does not live in mountains, preferring woods in foothills and in plain areas. These predators search for food even at the coastal strip, and frequently eat bodies of dead algocetids cast ashore during the storm.

Silver nev (Neopuma argentea)
Order: Carnivores (Carnivora)
Family: Cats (Felidae)

Habitat: Rocky Mountains in western North America.

Picture by Wovoka

Unlike other families of true carnivores, felines have evolved towards pure predation for a long time; all members of the family obtained food exclusively by hunting other animals. Unlike canids and hyenas, most wildcats were solitary animals with a vast individual hunting territory. This was especially true for big cats, such as lions, tigers, jaguars, and others, which made them vulnerable when the area suitable for their life began to shrink, initially due to human activity, and at the beginning of Neocene due to the Ice Age. Most of the big cats became extinct, and by the beginning of Neocene, the felid family had been represented almost exclusively by small wildcat species and their descendants. By this time, only leopard (in Africa) and cougar (in the New World) remained of the large felines.
In North America, cougar populations remained in the west of the continent, where they persisted to Neocene, having formed new species. One of these species is silver nev, an adaptable animal with a fairly flexible lifestyle.
Silver nev is a medium- to large-sized animal with pronounced sexual dimorphism: males weigh up to 60 kg; females are smaller, weighing 29-45.5 kg, depending on the population. The average length of this animal is about 130 cm (not counting the long tail), and the height at the shoulders is about 60 cm. Males are generally larger and of heavier constitution; southern populations are smaller and leaner than northern ones. Animals have quite dense fur, which allows this beast to live quite high in the mountains, about at the level of mountain meadows and higher, where they hunt large herbivorous animals – local deer and rodents, as well as large birds. In northern populations, wool is silver-gray, of almost monotonous coloration; in southern animals, a dark saddle-shaped area appears on the back and there is a blurred stripe pattern on the tail. Usually, silver nev attacks prey from an ambush, hiding behind a stone or a snowdrift, or sneaks up on its intended prey. Sometimes family couples of these animals act together: one beast distracts prey by somersaults and jumps, while the other sneaks up from behind or from the side and rushes on the prey.
Silver nev does not like to run for a long time, but it can make very long pounces, up to 3 meters in length. This is a fairly strong animal, and in a successful pounce, silver nev can knock prey off its feet, and then bite into its neck or muzzle and strangle it.
The breeding season of silver nev takes place at the end of winter: estrous females of this species begin to utter loud calls similar to those of a domestic cat, but lower and more bass, which attract males. If several males meet near one female, they fight for the right to mate, but the final choice is still made by the female. During the rest of the year, females are usually inferior to males. Only a female with cubs is ready to defend her prey, and even rushes at the male, driving him away.
Cubs are born in early summer, and there are up to 5 cubs in a litter. Like cougar cubs, they have a mottled coloration, which persists until the 2nd month of life. The litter is raised mainly by the female; the male lives nearby and is not interested in the cubs, but does not attack them while they are still small and live with their mother. By the end of summer, the young animals get a coloration typical for this species, but still remain with the female. She drives away the young by the beginning of the next year, especially if they are males. Females stay with their mother longer and go away on their own, usually when she goes into heat.
In the vast area of the range of this species, family relationships in this species take on various forms. In the south, this species is a typical polygamist: several females can live on the territory of the silver nev male, and he pairs with them in turn. Such animals hunt singly. In the north, in Beringia, where winters are longer and it is more difficult to feed even for an experienced hunter, silver nev often forms monogamous pairs. Family bonds bind a couple much stronger, and couples are more often permanent, existing for several seasons in a row. Couples spend most of their lives traveling after herds of their prey, spending the night in temporary dens. Sometimes in winter, silver nevs even hunt in groups, and they turn out to be more tolerant of their congeners by the standards of wild cats.
Further south, where the climate is milder and winters are shorter, the behavior of silver nev is more similar to that of a typical feline: it is polygamous and territorial, and beast of this species has a permanent territory, and territories of several females are located within the possessions of one male. During the mating season, he alternately mates with them, but does not take care of the offspring. However, at the moment, both populations of silver nev are representatives of the same species at the genetic level, and they may well interbreed with each other, i.e. the boundaries between populations with different behaviors are unclear, and there are various transitional behaviors between them.
The young become sexually mature at the age of 2 years. The life expectancy of silver nev is 16-20 years.

Further south, in southwestern North America, a related species of this cat, golden nev (Neopuma aurita), is widespread. This animal is a little bit (10-20%) smaller, with shorter golden- or reddish-brown hair, lighter on the belly. Golden nev lives in lands where there is no snowfall, but drought often happens, so it is more thermophilic and easily tolerates heat and lack of water. Golden nev does not form permanent pairs. Each animal has a vast hunting territory, more than half overlapping with the territories of its neighbors. The animal constantly roams the mountains in search of its prey – large mammals and birds. Unlike silver nev, which is mostly active during the day, the peak activity of golden nev is in the morning and evening twilight. During the day, the animal sleeps in shelters, and falls asleep for several hours at night.

Uecubu (Notacinonyx uecubu)
Order: Carnivores (Carnivora)
Family: Cats (Felidae)

Habitat: pampas of southern Patagonia.

Picture by Alexey Tatarinov

Hunting, the extermination of herbivores and the destruction of habitats have killed many large predators, including almost all big cats. Therefore, the world fauna right after the human epoch was represented for the most part by species not exceeding the size of a small domestic goat. In South America, almost all small cats disappeared – they became rare by the end of the human era, and the destruction of their habitats doomed them to extinction. One of the surviving species was Pampas cat (Leopardus colocolo). During the Ice Age, it managed to adapt to the cold climate, and its descendants increased in size. The pampas in the north harbor a more heat-loving fauna of predators, including the peculiar flightless herons, and in the cool grasslands and sparse forests of southern Patagonia, uekubu lives – the fastest of the descendants of the Pampas cat.
Uekubu belongs to large species of felids: body length 130-150 cm, tail length 70-80 cm, height at the withers – 90-120 cm, weight – 65-85 kg. The physique of this animal is graceful, despite its large size: this long-legged beast is a fast-running predator (the name of the beast is the name of the Araucanian god of evil). Its prey includes derermaras and true deer – descendants of brocket deer. The latter become its prey all year round, as deermaras migrate north for the winter. The hunting tactics of uekubu resemble those of cheetahs – the beast tries to get closer to the prey and quickly attack it from a short distance. But the animal pays for its speed with endurance: it has enough sprinting speed for no more than 300 meters of chase distance. In addition, the hunting tactics of the animal do not allow it to exist in mountainous areas and in dense forests. But in these habitats, this species is substituted by raptor cats (Felinoraptor spp.), which are physically stronger than uekubu and often take prey from these cats.
The coloration of uekubu wool is gray with darker spots on the legs and tail, as well as on the crown and nape. Winter wool is thicker and of much lighter color, being almost white with light gray spots. At this time, fluff grows on the animal’s paws, and the animal does not fall into the snow. Young animals are colored darker than their parents: their whole body has a spotted pattern, which gradually “fades” as they grow older, like in a cougar. In some cases, juvenile mottled coloration persists for life.
Breeding season in uekubu begins in late winter or early spring. Males chase the females and slightly pat them on the back with their paws, trying to keep them in place. At the same time, they emit loud squealing calls. Being animals of gracile physique, animals fight very rarely. Unlike cheetahs and most other felines, this species has a family that persists throughout the duration of the female’s pregnancy and the rearing of offspring. Pregnancy lasts 90 days, after which 3-4 kittens are born. Both parents are involved in the rearing of kittens. The litter hunts with the mother until the next breeding season, which makes the winter hunting of these predators more successful. At the end of winter, young cats begin to hunt on their own and the family breaks up. In some cases, the same male and female form a family for several years in a row. Young animals hunt alone in the first year of their independent life, and during this period the largest number of young animals perishes.
Females reach sexual maturity at 21 months, males at 33 months. Life expectancy is 15-20 years.

Quilla (Pallidopardus selenae)
Order: Carnivores (Carnivora)
Family: Cats (Felidae)

Habitat: highlands of the Andes – meadows, rocky scree.

Picture by Wovoka

Holocene proved to be a controversial epoch for the felid family. Many large species failed to withstand anthropogenic pressure and became extinct during or shortly after the human era. Many small species also disappeared, although domestic cats were very widespread: their descendants are found even on remote oceanic islands. The survived species gave rise to a whole bunch of forms, both large and small. Among them, strange raptor cats live in South America; one of their species inhabits the forests of the Andes. And after climate warming one of the descendants of the Pampas cat (Leopardus colocolo), which arose during the Ice Age, survived only high in the mountains, where it was superseded by raptor cats. This species is quilla – rather rare large predator of the highlands.
The total length of the body with the head is 123-130 cm, the tail length is 40-45 cm, and the height at the withers is about 60 cm. Weight is about 45-52 kg; males are slightly larger and darker than females. Wool color ranges from grayish-ochre to light gray with darker stripes and spots. The contrast of the pattern on the skin is low compared to the ancestors, hence the name of the genus. A crest of elongated hair grows on the head, forming a kind of forelock. The general appearance of quilla resembles a “moon cat” of the Peruvian Indians (the Moon goddess of the Incas). It is a solitary animal that inhabits alpine meadows, rocks, scree, and rock outcrops; sometimes it descends into mountain forests and valleys, but it does not stay there for long. Each individual has an extensive hunting territory, protected from its congeners.
Quilla feeds on large mountain-dwelling mammals (including those twice as heavy as the predator itself), but does not hesitate to catch birds and small mammals. Most often, this species attacks prey from ambush (stalking its prey near trails, salt pools, watering holes, laying in wait on rocks), less often it sneaks prey. When the prey is close, quilla catches up with it in several pounces, knocks it to the ground and strangles it. When quilla and raptor cat meet, the latter often wins, but they rarely come across – there are clear ecological differences between these species.
The mating season takes place in late autumn and early winter. Males find females by scent, chase them, and mate with them repeatedly. Encounters with rivals, which at other times are often limited to roaring and threatening displays, escalate into fierce battles during the heat season. Therefore, mature quilla males carry scars on muzzle, ears and shoulders – often the very sight of such a male is enough for an inexperienced opponent to retreat.
Pregnancy lasts 90-110 days. The lair is located in caves or hard-to-reach places. This species is characterized by a relatively slow rate of reproduction: there are usually 1-2, less often 3 cubs in litter; they are born blind, and the kittens’ eyes open 10-12 days later. At the same time, their first teeth appear and they start playing. At the age of 2 months, they taste meat for the first time, and at 3 month they learn how to hunt. Young animals begin to accompany their mother and observe her hunting, and also get small animals on their own. At the age of 15-18 months, they are already independent and begin to conquer their territory, and the female is ready to mate again. By this time, the female often has only one cub left. Maturity comes at the age of 3-4 years; in females it happens earlier than in males. Life expectancy is up to 16 years for males and up to 20 years for females.

Ch’aska (Pallidopardus aphroditae)
Order: Carnivores (Carnivora)
Family: Cats (Felidae)

Habitat: southern Patagonia, Tierra del Fuego, forests.

Picture by Wovoka

South American felines experienced certain problems in Early Neocene. Many of the Leopardus cats turned out to be quite rare as a result of habitat destruction and became extinct shortly after the start of the Ice Age. Domestic cats, being successful predators on other continents and islands, became extinct even earlier – their numbers were quite low here, and their descendants had been superseded by the descendants of true wild cats in the first millions of years after humans. On this continent, isolated in Neocene, felines survived and settled various natural zones. The pampas and mountainous regions of the continent were inhabited by raptor cats, descendants of the cougar. Jaguarundi descendants replace them in the forests, and the descendants of the Pampas cat (Leopardus colocolo) live in the harshest conditions – in the highlands of the Andes and in the far south of the continent, in Patagonia and Tierra del Fuego. Ch’aska is a large descendant of the Pampas cat from the cool forests of the south of the continent and the foothills of the Andes.
The body length of ch’aska is 2-2.5 m, the tail length is 70-75 cm, and the body weight is about 300 kg. Wool color is gray-brown, darker on the back, with a blurred spotted pattern on the sides, neck and head. Male is slightly larger than female. The legs of this cat are relatively short, allowing it to move in the undergrowth and among the bushes. Because of this, ch’aska is unable to run for a long time and most often attacks from ambush. Pouncing on prey – a deer, a groundsloth rodent or a peccary – the predator quickly strikes with its huge claws, leaving deep wounds on the prey’s body, and retreats. Its prey often dies from shock and blood loss. The predator chases the prey at a walk, waiting for it to weaken and fall. Ch’aska usually hunts 2 times a day – in the morning and in the evening (hence the name: in the Incas, Chaska is Venus, the goddess of sunrise and twilight). Sometimes it deprive other predators of their prey, and does not disdain carrion. Ch’aska is a solitary predator, although the territories of the male and female overlap. Such individuals often form a breeding pair.
The mating season is timed to autumn. During estrus, female leaves urine marks and scratches on the bark of trees. Due to the fact that the territories are quite large, females sometimes search for males themselves, leaving marks and checking them. The male chases the female for several days before she lets him coming closer – during this time the animals get used to each other and the female treats the male less aggressively. Mating occurs regularly for two to three days, after which the male leaves the female. The duration of pregnancy is 110 days, after which the female gives birth to 3-4 kittens. Juvenile coloration is gray with a pattern of black spots. Lactation lasts for six months, but by the middle of summer, young animals learn to eat meat. During the autumn shed, they get adult wool coloration. Young animals hunt with their mother until they find a suitable hunting area, usually before the age of two. By this time, they often hunt on their own and may not return to their mother’s lair for several days. Young animals reach sexual maturity at the age of 3 years. Life expectancy is up to 20 years.

Noonda (Deinothera nunda)
Order: Carnivors (Carnivora)
Family: Felids (Felidae)

Habitat: Zinj Land, tropical forests and woodlands.

Picture by Wovoka

In human epoch many large cats had practically died out because of disappearance of animals being their food, and because of direct extermination by people which saw the competitors and direct threat in them. Cats of genus Panthera included the largest representatives of family had suffered the greatest losses. Only leopard (Panthera pardus) could go through mass extinction at the boundary of Holocene and Neocene because it could eat small prey and was ecologically plastic species. This species also had suffered strongly because of hunting and destruction of habitats, and by the end of Holocene there were only isolated populations of these animals that was an incitement to speciation after human disappearance. One of Neocene descendants of leopard is noonda, the largest predator of Zinj Land, East African subcontinent. The name “noonday” descends from Swahili fairy tales where the huge man-eating leopard was called so.
Noonda is very large, tiger-sized cat. It is a predator of heavy constitution adapted to hunting for large prey. Forepaws are little bit longer and thicker than rear legs are, because of what noonda’s back is sloping a little. This species has bright red fur with large dark irregular-shaped spots. Ears of animal are black with white tips; on cheeks characteristic “whiskers” of lengthened hair grow, as if at Holocene tigers. Tail is very long; at males it is covered with rich wool with alternating black and white strips; at females and sexually immature animals wool on tail is less rich, colored monophonic black. Colouring of tail is very important at establishment of domination relations; at old males wool on tail is thicker.
Noonda prefers to hunt large prey – great goatlopes, bikifaru, megaardvarks and cataphractheriums. These cats attack prey from an ambush and actively use forepaws killing it. If prey is of rather gracile constitution, predator simply breaks its backbone by heavy paws; for strengthening of impact pads of forepaws are covered with thick cornificated skin. If prey has heavy constitution, noonda delivers to it blows by 10-centimeter long claws on internal side of forepaws. If the animal had not died after the first attack, noonda stops attack and simply follows prey while it will be lost from loss of blood. Because of heavy constitution noonda can not swarm up trees as good, as its ancestor did, and hides prey in bushes more often.
This cat is solitary territorial animal; each individual needs about 20 – 30 square kilometers of territory. Noonda males mark borders of the territory with urine, leaving it on stubs, branches and trunks of trees; females also use secretion of anal glands. The male’s territory includes partly or completely territories of several females. Meeting each other, males behave aggressively, but more often the meeting finishes without fight which can be resulted in drawing of dangerous wounds. Establishing their relations, males swing tail in sides, scratch ground by forepaws and growl loudly. Usually one having thicker wool on tail wins – it is a sign of presence of plenty of testosterone hormone in blood.
Male learns about readiness of the female for pairing by smell of urine, with which she marks her territory. The heat period at female lasts till about a week. All this time male keeps near to the female and frequently copulated with her, and leaves her at the end of heat period. Breeding rate at this species is rather slow. After three-monthly pregnancy the female gives birth to one up to four cubs in reliable refuge. Cubs are born blind and only 700 grammes weigh; spots on their wool are located denser. Since three months age cubs already start to show independence and even try to hunt small prey. After the cub has reached age of two years, mother banishes it. At the age of four years noondas reach sexual maturity.
Life expectancy of noonday is up to 30 years.

Red-masked lemur (Eulemur rubrifrons)
Order: Primates (Primates)
Family: True Lemurs (Lemuridae)

Habitat: forests and wooded plains of Madagascar

In Neocene, the geography of Madagascar island did not undergo any significant changes – only after the split of African continent and separating of Zinj Land this island was displaced eastwards in common with this subcontinent. Climate of the Earth became more humid, and the regions of Madagascar covered with woodlands had spreaded considerably. Also the human disappearance benefited to various inhabitants of the island, including the lemurs – the distant relatives of people.
Red-masked lemur is one of the more widespread Malagasy species. This is a rather large primate that reaches up to one-and-a-half meters in length, and one meter goes to the tail, which is covered with especially bright red fur. The snout of this mammal looks like dog’s one in shape, but is shorter and wider. Ears are small and bordered with a strip of elongated brown fur. The eyes are large; the color of the iris is sexually dimorphic: in males the iris is yellow, in females brown or dark orange.
The color of tail noticeably contrasts with the color of fur on animal’s body - this primate is covered in light grey fur with darker vertical strips. The nape, the back of the head, the rear side of neck and arms of animals of both genders are covered in dark-brown fur. A spot of ochre-red fur, which is located on forehead, temples and nose bridge in the adult beasts (hence the name) sharply contrasts with it. The snout, the cheeks and the lower jaw of these animals are white. The coloration of red-masked lemurs has an expressed sexual dimorphism and age-related changeability: females are colored lighter than males (the background color of fur may be almost white or slightly beige), and the adolescents have less developed stripes. These special features of fur coloration help the animals to follow and to track each other: red-masked lemur has well-developed chromatic vision, and animals exchange visual signals with each other with the aid of their vividly colored tails. But this primate also frequently uses its sense of smell in the search for food and to mark the boundaries of its territory with the aid of odorous urine.
The basic food of red-masked lemur includes various fruits, which these animals eat in a great quantity, up to 80% of the mass of their day ration. Nevertheless, they also diversify their diet with various invertebrates (mostly insects), and also with honey, nectar and some species of tree fungi, and also with fresh leaves.
Red-masked lemurs are social mammals living in rather large groups, which number from 15 to 25 animals. In each group there is the dominant male and its underlings, but the majority of animals are females and juveniles.
Due to the features of their diet, red-masked lemurs are migrating animals. Each group inhabits an extensive territory up to several dozens of square kilometers. The boundaries of each territory are not too strictly observed, and the border zones of adjacent group may take up to one third of each separate group territory. The markers left by animals rather tell the news about each group instead of claiming exceptional rights to the territory. The group of animals constantly roams through its territory in search of fruit-bearing trees, staying in one or another territory no more than till several days. Groups of lemurs are frequently followed by predatory birds and mammals attacking the old, young or sick individuals that fell behind.
Red-masked lemurs are equally confident both on the ground and in trees: their limbs are long and strong enough even to run at a galloping speed for short distances. And they often escape on the ground from predatory birds and snakes, especially in the woodlands.
The mating period of red-masked lemur takes place in the second half of spring, when mature males chase away the adolescents and fight with each other for the leadership in the group. Hierarchy is established by crying contests – the rivals shout to each other until one of them gives up and becomes silent. The alpha male obtains harem of 3-4 females, which have high rank in the hierarchy of the group, and the vanquished males can count only to mate with one female that stands on one of the lower steps in the group hierarchy. The alpha male does not prevent it, but it does not allow other males to approach to his own females, while they are in estrus. After half a year after mating females give birth to one or two rather large offspring.
The sexual maturity of young animals comes at the age of two years. The usual life expectancy of red-masked lemur is 10-12 years.

Hanging lemur (Scyolemur quadrimanus)
Order: Primates (Primates)
Family: Hanging lemurs (Pendulemuridae)

Habitat: Madagascar, rainforests.

Picture by Alexander Smyslov

In early historical epoch on Madagascar representatives of original family of lemurs still lived – so-called “sloth lemurs” (Paleopropithecidae). But after human colonization of island their destiny appeared sad: “freshest” of the found bones of these animals carry the traces testifying to hunting and cutting of carcasses of these animals. Thus, it is obvious, that they became one of many victims of human activity promoting impoverishment of island fauna.
After human disappearance and the ending of epoch of mass extinction the few survived species of lemurs had actively started to evolve, developing new forms and occupying accessible ecological niches. Species of lemur family (Lemuridae) changed especially actively. One of their descendants had mastered an ecological niche occupied earlier by sloths in America, and by lemurs of Paleopropithecidae family at Madagascar. It differs from ancestors in so great degree that represents the separate family Pendulemuridae. This species is hanging lemur.
Hanging lemur is medium-sized primate: it weighs about 10 kg at body length up to half meter. This animal has long tail which usually hangs downwards. The role of this tail in life of hanging lemur is great: it is used for recognition of congeners. At the tip of tail the switch of long hair of black-and-white coloring grows, carrying out alarm function. It is possible to tell, that it is “the mirror reflection” of its distant ancestor, ring-tailed lemur (Lemur catta), only turned upside down. Watching such switches, appreciable from afar, animals distinguish presence of congeners on next trees. In case of danger tail is drawn in, and animal nestles against the branch, densely clasping it by paws. In such position it is more difficult to attack it for enemy (usually for bird of prey). This lemur protects itself against predators from among mammals, biting strongly.
The wool of animal has the colouring appropriate to its usual position on tree: back is yellowish-brown, and stomach is dark, almost black. It is obviously expressed countershadow colouring: when sun lights up hanging lemur, light transforms it into flat silhouette difficultly distinct among branches.
This species of primates spends almost all life, hanging back downwards on tree branches (hence the name “Scyolemur”, meaning “lemur in shadow”). All paws of animal are prehensile and can work as hands, grasping branches. Because of it Hip joint is very mobile: if necessary, lemur can freely tear food from branch and bring it to mouth by hind leg. Fingers and toes are very long (the palm length is approximately equal to forearm lenght, and fingers make 2/3 of its length); thumb and big toe can oppose to other fingers/toes. The surface of palms and soles is covered with rough skin with advanced papillary combs. If necessary this lemur can swarm up tree trunk in the same manner as other lemurs, back upwards, clasping branches by hands and feet. This animal moves on the ground extremely seldom and very hardly, basing on external edge of feet and palms.
Neck of hanging lemur is almost as flexible, as at owls: the head of animal can turn to 270 degrees. Muzzle of animal is short and wide: the basis of diet of this animal is made of rigid leaves, including the leaves of trees containing rubber. Therefore hanging lemur has wide tuberculous molars and strong chewing muscles giving the characteristic shape to its head. Canines are strongly shortened in order to improve chewing. Stomach of this lemur is complex, five-chambered, with volumed “fermentive” department. Intestines are long, that allows taking as much as possible nutrients from such hardly digestive food. But due to food specialization hanging lemur can feed, not having a competition from the part of other species of animals. On head of animal there is white “mask” covering forehead, area around of eyes and nose bridge – it is visible from apart, and serves for recognition by animals of each other at the distance. Ears of hanging lemur are short, at their edges fringe of rich white wool grows.
Hanging lemurs are solitary animals. Only young lemurs, passing to independent life, spend any time at the same branch as their mothers and follow them. But later they start to lead independent life, and leave parents. Hanging lemurs use calls for communication. They are especially “vociferous” in the morning and right before rain, when they utter lingering call similar to sheep bleating.
Families are not formed at these lemurs, and male right after pairing leaves female. Two times per one year the female brings posterity. The cub is always sole; it is born with open eyes and the first days of life keeps on stomach of mother, clinging for her wool. Approximately at monthly age it studies swarming up trees, coming back to the female for feeding. At four-monthly age young lemur becomes completely independent. If the cub was born during spring rains, female is already pregnant again to the moment of its complete independence. In rather dry winter period female restores forces.
Young animals begin capable to give posterity at the age of about one year. Life expectancy of representatives of this species reaches 14-17 years.

Sleepy lemur (Tardigalago tenax)
Order: Primates (Primates)
Family: Bush babies (Galagonidae)

Habitat: Zinj Land, tropical rainforests.

Picture by Wovoka

Despite the general decline in the number and diversity of prosimians and the destruction of their habitat, bushbabies have proved to be a fairly successful group of primates. Due to their small size, they have maintained a fairly numerous population in small land areas not affected by human activity. They managed to survive to Neocene, although they lost some of their species. In continental Africa, they still remain in the shadow of the monkeys, their more progressive relatives. But their diversity has grown in Zinj Land, and bushbabies make up a significant part of the species of arboreal animals in that area. Among them, there are species that developed various kinds of lifestyle – from herbivorous ones to almost exclusive predators, from small to medium-sized ones. One of the representatives of this group of primates is sleepy lemur.
This species lives exclusively in the tree crowns and almost never descends to the ground. The body length of an adult is 30-35 cm; the tail length is 10-15 cm. Male is slightly larger than female. Wool is thick and velvety, of brown color with gray spots on the throat and chest. Wool coloring helps the animal to hide in trees among bark and epiphytes. Digits are thin and very tenacious, capable of grasping thin branches. Tail helps to keep balance on the tree, but its main function is to store fat: in well-fed animals, it is quite thick and cylindrical. Displaying an upturned tail is an important element of behavior when establishing a dominance relationship.
This species has large pointed ears covered with fur on the outside and large reddish-brown eyes. During sleep, the animal bends its ears forward and covers its eyes with them. Jaws are relatively short, and muzzle is blunted. Canines are short but pointed; premolars have sharp cutting edges.
Like its ancestors, sleepy lemur is a nocturnal animal. A significant part of the diet of this species consists of food of animal origin: it feeds on invertebrates and small vertebrates (most often birds, lizards and amphibians) that spend night in trees. Only about 10% of the diet consists of soft juicy fruits. The movements of sleepy lemur are quite careful and fluid; it gives the impression of an animal that has just woken up. It is especially noticeable when it gets close to the prey. But this impression is deceptive: it can move quite briskly, especially when capturing a fast-moving prey or while fleeing. Waiting for insects or lizards, this primate can freeze for a long time, and then grabs prey in one lightning-fast movement. Sleepy lemurs feed alone, but during daytime rest they can form groups of up to 7 individuals in shelters – females and their cubs, and sometimes single males.
This species has a poorly developed sociality. Usually, a clan of 3-4 females with cubs feeds in a certain territory, and the males live in neighboring territories and have individual possessions that are strictly protected from other males. Mating takes place twice a year, from April to June and from October to December. Males search for females actively, invading their territories, and quarrel loudly over individuals who are ready to mate. The voice of this species is a high-pitched thin squeal and a squeaky “barking”. Each particular female gets pregnant only once a year, so males are constantly competing for “free” females. Pregnancy lasts 150 days, after which 2 or less often 3 cubs are born. The female feeds and teaches the cubs for 7-8 months, and by the end of this period she mates again. Life expectancy is about 20 years, but usually less.

Feline marmoset (Carnosaguinus feliformis)
Order: Primates (Primates)
Family: Marmosets (Callitrichidae)

Habitat: tropical forests of South America.
Among primates, marmoset monkeys, marmosets and tamarins, represent a side branch of evolution. They retained some primitive features like claws and small body size. Their small size, unusual appearance and arboreal lifestyle have made them very vulnerable to human impact: they have suffered due to trapping and habitat destruction during deforestation. In Holocene, as well as during the Ice Age between it and Neocene, the species diversity of marmoset family decreased significantly. Only a few populations of the most common species have survived. But their descendants settled in the forests that were recovering in the Early Neocene and acquired some new features.
Feline marmoset is one of these species that has adopted a new lifestyle. It reaches up to 45 cm in length and weighs about 3 kg, which makes it a very large representative of marmoset family. It is rather dimly colored: the general wool coloration is gray-brown with faintly visible transverse stripes; its muzzle resembles cat’s one: it has large pointed ears, large eyes and well-developed canines in both jaws. The only thing that breaks the resemblance to cats is dark gray mustaches. There is a patch of bare skin on the chest – light gray in females and bluish in males. Juvenile has an entirely black coloration with a white spot on the lips – this coloration suppresses the aggression of adults and stimulates parental behavior. In this species, tail is covered with long black hair; the zone of black hair continues on the loin. Tail serves only as a balancer and helps to adjust the direction of the jump; feline marmosets easily and freely run along the branches and trunks of tropical trees and can make quite long jumps, especially for their size. Claws on the front paws are sharp and large, helping to kill small animals.
Feline marmoset is a predominantly predatory animal; it is the only primate species in the New World in which meat makes up more than 2/3 of the diet. Among the plants, this monkey chooses the species with the most nutritious seeds or roots – the leaves serve only to improve the taste of food or as a medicine. Unlike all related species, this species hunts at dusk: its eyesight is as sharp as that of Holocene douroucouli monkey. In the darkest hours of the night, these animals rest in a temporary shelter, avoiding encounters with owls, and during the day they sleep, hiding in a safe shelter like a tree-trunk hollow: it helps them to avoid birds of prey, the main enemies of small animals. Another dangerous enemies of these animals are arboreal snakes. This monkey feeds on large insects and spiders, non-venomous tree frogs and lizards, snails, and even ravages bird nests and catches bats in tree-trunk hollows. Usually, this monkey grabs prey with its paws and inflicts several bites with its canines, killing it. Molars have sharp cutting edges.
Like other tropical animals, feline marmoset has no pronounced mating season, and offspring appear at any time of the year. However, pairs are formed for life, and males help females take care of their cubs (at this species litters number 1-3 babies), even to the point that they carry cubs on their backs so that the female can rest. During the hunt, one of the parents stays with the cubs.
The behavior of feline marmosets is quite adaptable; individuals of this species can be either territorial or roam the jungle quite easily, but they do not descend to the ground. It is an exclusively arboreal species that leaves trees only to swim across a body of water if there are no lianas or branches on which it may be crossed above the water. Usually these animals keep in breeding couples, but sometimes twins do not part with each other all their lives, and their kinship binds two breeding couples into the whole group. Young animals become independent at the age of six months, and a one-year-old female already brings offspring.
Feline marmosets do not live longer than 10 years, they often die earlier.

South-American barbudo (Barbudo papioformis)
Order: Primates (Primates)
Family: Cebids (Cebidae)

Habitat: north of South America, forests and bush in foothills.
Primates had appeared in South America in early Oligocene, and during their natural history were represented by exclusively arboreal forms having greater or lesser degree of specialization to tree-climbing. Some species of South American monkeys had evolved tenacious tail allowing to cling to branches and to hang on it. All these monkeys form a group of New World monkeys, which prominent feature were very widely placed nostrils.
In Holocene epoch many kinds of New World monkeys were destroyed as a result of hunting, catching for zoos and deforestation of Amazon basin. The most specialize arboreal and local endemic species had especially strongly suffered. But some species managed to survive, to go through climatic changes at the boundary of Holocene and Neocene, and to inhabit again forests of South America, which had gradually started to restore in early Neocene. Common squirrel monkey (Saimiri sciureus) became the most successful species of South American monkeys. Its success had been determined by a number of factors: they easily adapted to life in broken forests and bush, frequently went down and could easily move on the ground, were numerous and differed in small size. The majority of monkeys of Neocene South America descends from Saimiri. One of these species is large South American barbudo.
Barbudo are medium-sized monkeys (body length is about 40 cm) having rather massive constitution. They live in big groups on the ground in forests of various types in central and northern part of South America. These monkeys meet especially frequently in foothills and among bushes, where they find a lot of food. They are able to climb on trees, but do it reluctantly, because they are more adapted to life on the ground. Young individuals climb on trees more often.
Barbudo has massive trunk with voluminous stomach. Front and hind legs are of approximately equal length, therefore the back of animal is slightly inclined back. Tail of barbudo is very short (about 10 centimeters long); with its help monkey can only express the mood, and it does not take any part in movement on trees.
Head of barbudo is rounded and has short strong jaws. Males have large canines; they frighten contenders and defend against predators with their help. Females have lesser canines, and during the repulse of predator attacks they keep near cubs in rear of the group while all males of the group in common attack predator, uttering loud cries.
The body of barbudo is covered with greyish-yellow wool; back and waist are brown. Very long wool on head is very remarkable feature of appearance of barbudo. On nape and neck the mop of rigid black hair grows as a mane, falling on shoulders and reaching up to the middle of back and closing neck. At males the magnificent beard covering throat and partly breast grows (hence the name, literally meaning “bearded”). Hair of the top part of head are short and light, and consequently monkey looks as though grown bald though actually only the small part of skin on head is lack of wool. When monkeys move through grass and bush, long hair of mane protect body against pricks and scratches. Mane and beard serve for demonstration in male duels – despite of frightening appearance, males of barbudo do not enter fight with each other, and confine themselves only to demonstration of menace and loud cry. In heat of the conflict male can seize by paws a trunk of small tree or bush and start shaking them, but never rushes to another male.
The face of barbudo is covered with short white wool. Both males and females have rich eyebrowes – it is a protection against insects and dust, important at life on the ground. On the face of barbudo there is rather small site of hairless skin – it is a nose and the bottom part of nose bridge, area between nose and mouth, and area around of mouth. This skin is brightly coloured, and the shade of colouring varies depending on physical and emotional condition of animal. At males the naked skin on muzzle is colored crimson-red color, at females it is pink. At young animals skin on muzzle is bright pink. At males there is also a site of naked skin of red color on breast. During menacing demonstration males can rear on hind legs, showing brightly painted skin of breast to each other. Thus they raise head, in order not to close breast by beard, and it gives to their conflict comic similarity to dispute of old men. In general, by behaviour barbudos resemble African baboons of Holocene epoch, but differ from them in considerably weaker aggression.
Barbudo has large eyes and good full color stereoscopic sight got from ancestors. With the help of keen sight animals notice berries and insects making a significant part of their diet. On hands at these monkeys thick strong nails grow, due to which animals can rummage in ground in searches of larvae and roots. But at them the thumb can not oppose to fingers – it is a common feature of New World monkeys.
Monkeys spend a lot of time in bush and underbrush, therefore sound communication occupies the significant place in their life. The voice of these monkeys is rich in various sounds; it includes grumble and grunt, cries of various tonalities and melodious twittering. Very much advanced hearing helps to warn beforehand about approach of predators. Having found out a predator, monkeys give the alarm, squalling shrilly. Their voices serve as the warning for forest inhabitants, like in Holocene voices of deer, langurs and peacocks notified jungle on presence of tiger.
In group of barbudo there are some leading males, which copulate with all females of the group by turns, therefore it is rather inconveniently to define, from what male cubs are born. Young males had not got to the circle of group “elite” have no opportunity to couple to females: females do not admit to themselves males of low rank. It is possible to raise the rank in group by only way: to protect herd against predators and strangers from other groups, and to concern loyally to females, occasionally allowing them to steal the found food. Such behaviour reduces the amount of disputed situations in group.
Once a year the female gives rise to one cub. It strongly differs in colouring from adult individuals: it has golden wool, and nape and lateral parts of head are grey. The cub is looked after by the female, but she allows dominant males to clean wool of the cub and to treat him with found forage when it grows up.
At the age of one year the cub becomes independent, and the difficult period of its life begins – it becomes “adolescent” to whom children’s pranks are not allowed. “Adolescents” keep by unite group, and frequently unite with coevals from other groups, or pass to the next groups one by one, especially if those groups are small. Three-year old male reaches blossoming of physical force, and young female at this age already gives rise to the first cub. Life expectancy of barbudo reaches 15 – 17 years.

Notopongo (Notopongo tardus)
Order: Primates (Primates)
Family: Cebids (Cebidae)

Habitat: tropical forests of South America, forest canopy.
The mass extinction at the turn of Holocene and Neocene affected a significant number of species of New World monkeys in South America. Many species of these primates became extinct, and the survivors persisted in small populations in relict “islets” of forest vegetation. Most species of South American monkeys of Neocene epoch are descended from squirrel monkeys (Saimiri), although there are some descendants of sakis and night monkeys. The largest monkey in South America is mapinguari (Mapinguari giganteus). But this species lives on the ground, and the largest arboreal species is notopongo, a very large, slow-moving monkey that constantly lives in the canopy of South American forests. This species descended from squirrel monkey, but its physique has undergone significant changes due to its lifestyle.
Notopongo is a kind of “koala” among monkeys, being a slow-moving browsing species. Body length of an adult is about 60 cm, but some individuals (mainly males) are even larger. The average weight of a monkey of this species is about 60 kg, adult males reach 80 kilograms. Extremities of this monkey are quite short, with prehensile fingers and toes, but the thumb is not opposable to other ones. There are large sciatic calluses on the buttocks, covered with thick rough skin – this monkey spends a lot of time sitting on branches. Its hind limbs and forelimbs are about the same length. What is especially noteworthy is that the tail of this species has not lost its grasping function. Tail is up to 1 meter long, being very strong and muscled. The lower surface of the tail is covered with hairless skin with numerous papillary ridges. Sitting on a branch, this monkey wraps its tail around it and locks itself firmly, freeing its hands for feeding.
Wool coloration of this species is faint – olive gray with a white spot on the belly and groin. Soles, palms, and underside of the tail are covered with hairless dark gray skin. Animal’s face is in stark contrast to this coloration: it is covered with bare pink skin and bordered by a strip of black fur. In males, the hair on the cheeks and chin, adjacent to the strip of black hair, is colored yellow. In females, the wool in these areas is only slightly lighter than the background color of the body. In addition, males have a larger forehead (more precisely, a larger area of hairless skin above the eyes). Nose is short, with widely spaced nostrils.
Canines of this monkey are short, jaws are large, and the molars are wide. It is so due to the need to chew a lot – the animal feeds on fibrous plant food. To attach the chewing muscles, a sagittal ridge develops on the skull, like in a gorilla, which is why the heads of animals of both sexes look like a head of gorilla male in profile.
Notopongo feeds almost exclusively on vegetative foods, adding to them some food of animal origin – bird eggs, large insects and arboreal reptiles and frogs. But the main food of this animal is leaves and young shoots of plants. Notopongo has a large three-chambered stomach with a large “fermentation chamber”, where symbiotic bacteria and protozoans break down cellulose. The intestines of this monkey are also very long: it helps to absorb a significant part of the nutrients. Unlike ruminants, notopongo does not regurgitate fermented food for repeated chewing.
This species lives in small groups of one male and 2-3 females with the juveniles of the last two litters. The female gives birth to one cub once every two years. The cub has very light-colored pinkish-white skin on its face and dark brown fur. For the first 3 months of its life, it is completely dependent on its mother and moves on her back. At the age of 9-10 months, the juvenile can already feed on its own; its connection with its mother becomes purely psychological. After the birth of a new cub, the previous cub helps the mother take care of it, and even carries the sibling on its back during the rest. Puberty occurs at the age of 4 years, and life expectancy reaches 40 years or more.
This primate is not very sociable. Males declare their territorial claims in the morning with loud calls, and during feeding, the family group communicates with a small set of monotonous sounds. Such simple behavior evolved due to the simplicity of notopongo lifestyle. During the defense of the territory from a stranger, the male screams loudly and shakes the branches, and if the stranger does not retreat, something like a boxing match ensues between the animals, when the males beat each other with fists, having fixed hard on the branch with the help of tail and feet.
Notopongo prefers to live in forests, where there a lots of lianas in canopy. Animals deftly move between trees using liana “bridges”. They rarely come to the ground, doing it only if they have no other way to get on the neighboring tree.

Patagonian megacebus (Megacebus patagonicus)
Order: Primates (Primates)
Family: Cebids (Cebidae)

Habitat: Atlantic coast of South America, subtropical areas.
In the human epoch, almost all New World monkeys were exclusively arboreal, and their distribution was limited to the tropical forest zone of the continent. During the human epoch and at the turn of Holocene and Neocene, there was a sharp reduction in the area of tropical forests. This caused the extinction of a significant number of species of New World monkeys, and directed the evolution of some species to adapt to life on the ground. In Neocene, there are several species of New World monkeys that lead almost exclusively a terrestrial lifestyle and are ecological analogues of baboons and gorillas. Some of the ground-dwelling monkeys descended from squirrel monkey, but some of them are descendants of capuchin monkeys (Cebus). Having inherited a well-developed brain from their ancestor, capuchin monkey descendants turned into the most exact behavioral analogue of great apes in New World, although they do not look very similar to them in appearance. They manage to survive alongside specialized primate species due to their adaptable behavior. The representative of this branch of primates in Neocene is Patagonian megacebus, the only representative of its genus.
Megacebus is a large prehensile-tailed monkey, having a convergent similarity to a baboon and capable of standing and moving on hind legs for a while. Erect height is up to 160 cm: body length is up to 80 cm, plus hind legs of the same length, as well as a tail up to 120 cm long. Thumb on the hand is opposable; on the foot it is outstretched from the other toes, but less than thumb on the hand. Despite its predominantly terrestrial lifestyle, the tail remained prehensile, with bare skin on its underside; papillary ridges are well-developed on this skin. Tail serves this species for communication purposes: while moving on the ground, these monkeys hold their tails vertically. The cub clings to the parent’s tail with its tail, and the adult animals fix with its help on the tree during the overnight stay. At the tip of the tail, the hair is colored bright ochre-red and has a signaling function; the general body coloration is light brown to yellowish. Skin around the eyes and nose is hairless and dark gray. A yellowish-white beard grows on the throat: small in females and large in males, often extending to the cheeks. The weight of an adult is about 50 kg.
Head slightly resembles the heads of some great apes, having massive, strong jaws and a parietal crest for attaching the chewing muscles. A strip of elongated hair grows atop of the crest, increasing the size of the head visually. Brain is relatively large, and the animal surpasses the Old World monkeys in terms of intelligence. Jaws are enlarged and strong, but the canines are reduced – this is an adaptation to chewing a significant amount of rough food.
Megacebuses live in fairly large herds along the shores of freshwater bodies, and numerous populations live on the seashore and in estuaries. This species is omnivorous, and a significant part of its diet consists of food found in water: tubers and rhizomes of plants, small fish and crustaceans. Animals from the seaside herds willingly feed on crabs, whose shells they smash with stones. With the help of sticks, these primates dig up the bottom of the freshwater reservoir in search of plant tubers. On land, these monkeys feed on fruits, small animals, and the leaves of herbaceous plants. The composition of the diet varies depending on the area and the established habits of the herd.
This species is social, keeping in groups of up to 20 individuals. There is an alpha male and an alpha female in the group, usually the “eldest wife” of the herd leader. Males and females establish their own hierarchy, which usually does not relate to the relationship between the sexes. Breeding adults keep in pairs: like most New World monkeys, this species is not prone to polygamy, and males participate in the upbringing of cubs. Male can carry the cub on his back for longer than the female, handing him over to her only for feeding and when the herd is attacked. The dominant male usually leads the defense of the herd and determines the places and routes of movement when searching for food, and the dominant female is his “deputy” in all other cases, except for the defense of the herd. She also settles conflicts between females and males, as well as among females. Older females act as “babysitters” and can even raise orphaned cubs.
Megacebus defends itself from enemies with a kind of “psychological attack”, using loud screams, throwing stones and dirt. In particularly serious cases, sticks and even teeth can be used if a direct collision with the enemy cannot be avoided. When confronted with their congeners, megacebuses limit themselves to noisy displays: conflicts do not reach the same level of intensity and brutality as in chimpanzees of the human era.
Once every 2 years, a female gives birth to one cub. Twins may be born in one case per 10-15 births. The cub is almost completely dependent on its mother in the first year, and by the end of the second year of life it becomes relatively independent, but retains relationships with its parents and peers. Usually, the females move from one group to another, while the males remain in the parent group. Puberty occurs at the age of 4, and life expectancy reaches 30 years or more.

Amini (Allocebus amini)
Order: Primates (Primates)
Family: Cebids (Cebidae)

Habitat: seasonal tropical forests and rainforests of Central America.
The species diversity of New World monkeys suffered serious damage during the human epoch. The extensive cutting of the tropical forests of America has led to the extinction of a number of local species, as well as specialized arboreal forms. Capuchin monkeys (Cebus), which already demonstrated flexible behavior and high mental abilities in the human era, had got a good chance of survival in difficult conditions. These adaptations allowed them to survive in a changing environment and make full use of the scarce resources of the remaining fragments of tropical forests. A significant number of New World monkeys in Neocene epoch are their descendants. One of these species is amini, a descendant of Panamanian white-headed capuchin subspecies Cebus capucinus limitaneus, which lived in Honduras and Nicaragua. After the opening of Panama Strait, it evolved in isolation from the South American forms.
Amini is a relatively small monkey species: adult animals reach a length of 33.5-45.5 cm, excluding the tail, and weigh up to 4 kg. Males are larger than females. The tail is up to 55.5 cm long, with a prehensile tip, and the underside of the tail is covered with hairless skin with developed papillary ridges.
Wool coloration is dim, mostly black, but the neck, chest, throat and shoulders are bluish-gray, and in older animals they turn gray noticeably with age. Face is hairless, of light cream color, and the hairline on the forehead is higher in males than in females. A characteristic feature of the coloring is the presence of dark markings above the eyes, visually increasing the size of the eyes.
The thumb on the hands is opposable, like in Old World monkeys. Being quite long and strong, it allows manipulating small objects. Palms and soles are hairless and covered with light pink skin.
Aminis are diurnal animals that like to spend most of their time in trees, although they often descend to the ground. On the ground, these monkeys move mainly on four limbs, occasionally standing on two legs to free their hands for manipulation. It is a social species that forms large groups of up to 50 animals, consisting of 70% females. Males in such groups are related by blood, and females, as a rule, come from other groups.
Aminis are omnivores. The basis of the diet is 50% vegetative food, and 50% insects and partly meat. From vegetative food, they consume fruits, flowers, plant sprouts, young leaves, and seeds. These monkeys have a thing for nuts, which they can break by stone knocks. Of the insects, these monkeys prefer grubs, caterpillars, ants and their larvae, as well as bees and wasps. They also hunt small vertebrates such as frogs, lizards, birds, and arboreal rodents. These monkeys love to ravage the nests of local birds – tototl, chahuiztli and parrots – and eat eggs and chicks. Hence the name of this species: “amini” means “hunter” in Nahuatl.
A special place in the diet of amini consists of social hymenopterans – ants, bees and wasps. To hunt them, monkeys use a special bark-peeled stick up to 30 cm long, which they stick into the insect nest, gathering insects on the stick and eating them. When ravaging bee nests, monkeys also eat honey. They are capable of raiding even the nests of stinging bees, descendants of the Africanized bee. To scare away insects, aminis use the greenery of strongly smelling plants, which they rub against their paws and some individuals even rub it on their face and ears. It is a cultural tradition passed down through generations: different groups of monkeys use different types of plants to scare off insects, and sometimes “exchange experiences” when animals move from one group to another. They also use the same plants to repel blood-sucking insects.
Aminis have different strategies for hunting pochteca ants and conquistador ants. Capuchin monkeys can attack the nests of pochteca ants only in conjunction with the ant-eating skunk: they follow the beast, eating the ants that he did not eat in the ravaged anthills. They can hunt conquistador ants not very often – only when an army of these insects passes through the territory of a group of monkeys. They learn about the coming and location of the ants by the calls of tototl bird following the columns of ants. By calling to each other, they inform their congeners about the route of the insects. Neighboring groups of monkeys also listen to the voices of their relatives and search for columns of army ants.
To catch ants, they hang from young trees or vines, clinging to them with their tails and hind legs, and with their front paws they catch ants by fishing them out of the column with a stick. After catching an ant, the monkey quickly bites off its abdomen and chest, and rub off the head still clinging to the twig against a nearby branch. When the irritated ants start attacking in too many numbers, the monkeys escape from them by climbing higher into a tree. During the conquistador ants’ passage through amini territory, each monkey can eat up to 1,000 insects.
Aminis are polygamous animals that do not form permanent mating pairs. A male can mate with several females; a female can also mate with several males, but the dominant male has the best chance of mating. All males of the group take equal care of the cubs, but they calmly accept the appearance of new females in the group with cubs from males of other groups. As a rule, young animals leave the parent group – only young high-ranked males can gain a foothold in it. Young females quickly find new groups. Low-ranking males form male “gangs” that can turn into fully realised groups when females join them.
The main enemy of these monkeys is yaraha. Sometimes snakes and birds of prey attack them. Animals have a sophisticated danger warning system, and different signals mean different kinds of predators. These monkeys mob large predatory mammals and owls, forcing them to hide and move away from the feeding and sleeping areas of monkey group. Aminis often defend themselves from snakes, striking reptiles with sticks. It happens that they manage to beat a reptile to death, and then they can even tear the skin and eat its meat.
Pregnancy lasts six months. There is usually one cub in a litter, but twins are not uncommon. Most often, childbirth occurs during the dry season between December and April. The mother carries the newborn on her back until the age of six weeks. Upon reaching the age of five weeks, the cub can leave its mother for short periods of time and by the age of three months it moves independently, climbing on its mother’s back only in case of danger. The cubs feed on their mothers’ milk for up to the age of 9 months. Both males and females take part in the upbringing of offspring.
Like other capuchin monkeys, these primates mature relatively slowly. Puberty begins at the age of three. However, on average, females successfully raise offspring only at the age of 5-6 years. Males become reproductive only by the age of ten. However, the survival rate of offspring in this species is very high, which compensates for the slow reproduction rate. Life expectancy is long enough for primates of this size and can reach 30 years. Some individuals are even capable of reaching post-reproductive age.

Sua (Cheirocebus gracilis)
Order: Primates (Primates)
Family: Cebids (Cebidae)

Habitat: Amazonian forests from the mouth of the Amazon and Hippolyta to the foothills of the Andes.
In Neocene, the most part of the primates of the Amazon rainforest is represented by the descendants of marmosets, small monkeys that most easily restored populations after the human disappearance and the return of forests after the Ice Age. Their neighbors are the descendants of owl monkeys, sakis and capuchin monkeys. One of the latter was the tufted capuchin (Sapajus apella), quite common, evolutionarily flexible and having the skills of tool activity. Sua, its descendant, is one of the most numerous primates in the region.
Sua is one of the largest inhabitants of tree crowns. It is an animal of graceful build, with a body length of about 90 cm, a tail and arms of up to 1.5 m, and a weight of about 15 kg. The male is larger than the female. Wool color is not too bright – from brown to black with individual variations. If notopongo, its neighbor in the forest canopy, is a slow-moving animal like a koala, then sua is its complete opposite. It moves through the forest like Holocene gibbons or a long-armed lemur – it “walks” on its hands, hanging from the branches. Unlike the brachiators of the Old World, this monkey moves slowly, wraps its entire hand around branches, regularly securing itself during the movement with its tail and can hang on its tail like the spider monkeys (Ateles) of the human era. This species is most often found in flooded areas of the forest, where it easily moves over water using liana stalks and tree crowns. During the dry season, sua spends a significant part of its time on the ground.
Sua feeds mainly on leaves, fruits and nuts, which it cracks with stones or branches of hardwood, using them like a hammer. Sua intentionally descends to the ground in search of suitable stones, which it carries up into the crowns of trees and hides in the tree hollows. In some hollows, several kilograms of stones accumulate, which these monkeys save for cracking nuts. Storage holes are remembered by monkeys, and all members of the herd know their location perfectly well. Hand of sua bears the features of specialization in brachiation – the thumb is strong, but noticeably shortened, the tips of fingers are flattened, and the palm in general is elongated. Therefore, the ability to instrumental activity in this species is somewhat limited compared to other species.
Sua can also eat eggs, small birds, reptiles and rodents. Monkeys of this species are found in groups of 10-12 adults (of which 1-3 are males, others are females) and young animals. The dominant male wakes up and searches for food first; he also leads the group through the territory. They have a specific route through the forest, but the animals regularly check new areas of their territory. Every morning, a group of suas climbs into the treetops and basks in the sun for a while, and then begins a “concert” of hoots and screams – this is how they claim the territory. This species got its name for its love of sunbathing (Sua is the sun god of the Muisca). During the morning “concert”, males utter loud hoots, often in unison, while females and cubs support them with high-pitched squeals.
The breeding season is not pronounced in this species. At any time of the year in sua clan it is possible to find both a ready-to-mate female and mothers with cubs. The female, being ready to reproduce, has enlarged genitals, and a red patch of bare skin appears on her chest among the fur – this is a visual signal for males. At this time, the dominant can especially often bully subdominants, and conflicts in the group become noticeably more frequent. Pregnancy lasts about six months, about the same time the only cub depends on its mother. However, by the end of this period, she may become pregnant again. While the cub is small, its wool color is light brown or gray. It is a signal of its status in the group, and it is allowed to do a lot – sometimes dominant males, strengthening their authority in the group, can nourish the cubs and play with them. At the age of 7-8 months, the wool color of the young animal changes to adult type, and the time begins to struggle for a place in the hierarchy of the clan. At the age of 18-20 months, the animals are already completely independent. Being three years old, young males are driven out by the dominant and form bachelor “gangs” on the edge of the territory of adults. Young females also gradually leave the parent group, moving to neighboring clans. At the age of 5, the animals are fully mature and conquer their own territory and females, sometimes luring them away from neighboring clans. In some cases, males even abduct females, making secret forays into the territories of their neighbors. Life expectancy is up to 40 years.

Banshi saki (Neomyrikina banshi)
Order: Primates (Primates)
Family:
Sakis (Pitheciidae)
Habitat: Amason region, rainforests and woods in foothills.
On boundary of Holocene and Neocene big tests for durability expected the primates order. The majority of representatives of this order in the daily life is strictly connected with woods. Here they find shelters and food. And when on boundary of Holocene and Neocene the global congelation began, the majority of primates has died out. In New World in Holocene this group was submitted by three families which number and variety were fairly undermined by human activity. Therefore chances of survival at most part of species were minimal. But nevertheless, among these animals some ones were to found has gone through global ecological crisis and has successfully occupied Neocenic woods.
When night goes down on rainforests of Amason region, it is possible to see some representatives of Neocenic monkeys of New World. In moonlight in underbrush small groups of night monkeys banshi saki wander. These animals are rather large for monkeys of New World: length of body of adult individual is up to 50 cm not including long tail. They are colored rather dimly in comparison with monkeys of Holocene epoch. At these primates head is covered with white wool, on neck, cheeks and crown long white hair forming original “pallium” grow. Very big brown eyes with round pupils indicate that it is nocturnal animal. In addition eyes are “penciled” from above by black wool. Only on chin males and females have red beard (at males it is much longer, than at females). Males in addition are decorated with rich white moustaches which are hanging down downwards from corners of mouth. Bodies of these monkeys are covered with dense grey wool, on chest and stomach wool is darker. The tail tip is white, but set off by black ring.
Jaws of these monkeys are short; at males large canines slightly jutting out from closed mouth are advanced. Nostrils as at all wide-nosed monkeys are bordered by wide nasal sept. The forward part of muzzle at the adult banshi saki is covered with thin wool, and at old animals it may be hairless at all. Ears are short, rounded; only their tips jut out from wool.
Hands and feet at banshi saki are hairless, covered with grayish-pink skin. The thumb at these monkeys does not oppose to others (this feature distinguishes monkeys of New World from other monkeys).
Banshi saki is one of the cleverest inhabitants of Amazon woods. At them there are rather large brain and complex behaviour including set of acquired skills, carefully kept in collective experience. Monkeys keep contact with each other uttering various sounds: they howl, chirp, smack and squeal silently. In total in their “dictionary” there are some tens of sounds and their combinations. Besides they watch white tips of tails of the neighbours, flashing in darkness. These monkeys distinguish colors rather badly, but their night sight is very keen.
Groups of these original primates amount up to 20 individuals, and they are headed with dominant pairs: all males submit to the male, the female bosses over all females of group. If the dominant male chooses to itself the female not belonging to number of animals of the supreme rank (at these monkeys pair is forming according personal sympathies), the group status of “Cinderella” automatically grows.
These monkeys wander in forest, finding drop fruits, insects and small vertebrates on the ground. But it is rather dangerous to make it: at night numerous predators wake up and go to hunt. Usually these monkeys are very cautious, and some individuals of medium rank are sentinels of group. Such duty allows them to lift the social status though prevents to search for food normally. Feeling approaching of any predator sentinels notify group about it by sharp squeal. Usually monkeys try to save from predators on trees. If they can not make it for any reasons they play awful performance for which have received the name.
Frightening off the enemy, banshi saki spread manes asides, having turned by faces to the enemy. Their heads turn to terrible masks: stains above their eyes look on the background of white mane as huge eyes, and spreaded beard seems an aperture of huge opened mouth. Moustaches of males besides create impression of canines in “mouth”. This performance is accompanied by loud shrill squeal (in the English folklore banshies are creatures remarkable in heart-breaking voices). To seem larger monkeys rise on hinder legs. Then the white mane is even more brightly appreciable on the background of black stomach. Usually not any predator endures monkey’s “performance” for a long time, preferring to run away. But even if its hunting appears successful and one of monkeys becomes its prey, banshi sakis all the same cry at the predator by all group, chasing it forthwith – it can secure them against the following attack.
Once a year the female gives rise to two cubs. They at once seize wool on her back, and first two weeks of life they travel on mother. Gradually young monkeys start to master the world, to try food of adult animals and to play with neighbours. Half year old animals already move independently, and one-year-old ones live independent life. At the age of two years young animals can have posterity. Life expectancy of banshi saki reaches 15 years.

Troll saki (Geopithecia tarda)
Order: Primates (Primates)
Family: Sakis (Pitheciidae)

Habitat: Andean mountain forests.
Sakis were one of the few groups of New World monkeys that survived the era of anthropogenic pressure and the decrease of the area of the rainforests during the historical era and the Ice Age that followed. Trapped in relict islets of jungles and mountain forests, they found themselves in an “adapt or die out” situation. Some of the populations had become extinct at that time, but the Rio Tapajós saki (Pithecia irrorata) survived, and there are its descendants in the Neocene fauna of the Earth.
Troll saki, a large, heavy-built ground-dwelling monkey, lives in the mountain forests of the Andes. The body length of an adult is up to 120 cm, the weight is 50-60 kg; the physique is very massive, and its limbs are shortened compared to the arboreal forms of the human era. The wool of this monkey is thick and dense; it helps to survive cold nights, although during the day it can even be hot in such a coat for monkeys. The background coloration of the wool is gray or grayish-brown; a mane of rusty-red, brown or black hair grows on the male’s head. On the cheeks and forehead, face is covered with thick short hair; the bare skin around the eyes, nose, and lips is pale pink, and it turns red in aggressively behaving animals. The tail is short and not prehensile; it has no balancing functions. The position of the tail expresses the mood of the animal.
The skin on the feet and palms is dense and heavily keratinized. The thumb on the foot is actually non-opposable.
Jaws of the animal are massive, enlarged, having short canines. Molars are tubercular and have thick enamel layer. Masticatory muscles are well developed, and there is a sagittal parietal ridge for their attachment. Because of this, the growth of cranial region of the skull terminates very soon; brain is smaller compared to related species, and the behavior is relatively simple.
Troll saki lives on the ground, feeding on tough vegetation. Therefore, everything is used for food – stems, leaves, seeds, nuts and mushrooms; the monkey easily chews young branches of shrubs. These primates rarely feed in trees; mostly light-weighted juveniles do it. But they get fruits and mushrooms from trunks and branches more often. Such a lifestyle reduces competition with mapinguari – the huge distant relative of this species. Due to their specialization in hard-to-digest food, the intestines of this species are long and have a voluminous cecum, and the animals themselves are relatively slow and spend a lot of time chewing and resting.
Troll saki lives in family groups of 2-5 adults with cubs and juveniles. Animals communicate by hooting, rumbling, and tapping their palms on roots and earth. Grooming takes up a lot of time in their lives, and females are especially willing to groom the male’s mane. The male dominates the group and does not tolerate other males near his family. At the same time, females pass to other groups relatively easily.
The mating season is not pronounced, and at any time there are females with cubs in a group of these monkeys. The reproduction rate is slow: pregnancy lasts 250-270 days, one cub is born, in one case out of 175 twins are born. The female can hardly cope with caring for the twins, but one of the cubs is more often taken care of by any childless female, and the survival rate of the twin cubs is quite high. For five months, the cub feeds on milk, but already in the second month of life it begins to taste the food of adults. A year after giving birth, the female is ready to mate again. Young individuals live with their mother for up to 4 years, and then young animals can leave the group. This is more often done by females who go to other males. Among the males, the most impatient and ambitious, but non-experienced ones are expelled. Such ones form bachelor groups that conquer their own females. Occasionally, bachelor groups of males kidnap females from groups or arrange a “raid” on family groups, thrash the dominant male and forcibly mate with the females. Troll saki reaches puberty at the age of 5, and its life expectancy is up to 45 years.

Mapinguari (Mapinguari giganteus)
Order: Primates (Primates)
Family: Sakis (Pitheciidae)

Habitat: mountain forests of South America, bush thickets.
In human epoch South American monkeys represented completely or mainly arboreal forms. Their sizes varied from very small up to medium. The species comparable in size to African gorilla lack among primates of New World.
At the end of human epoch the situation had changed: forests were cut down and only small islets remained of solid forested areas lasting continuously tens and hundreds of kilometers. In ice age the rests of humid tropical forests had receded to banks of large rivers. As a result of these changes the part of forest inhabitants had died out (it had affected large species in especially great degree), and another part had been compelled to adapt to other habit of life – life in open spaces, bush thickets and mountain forests.
Bush thickets and forests with rich underbrush are inhabited by one descendant of former forest inhabitants – huge species of ground New World monkeys, mapinguari. It is a huge descendant of white-faced saki (Pithecia leucocephala) - one species of South American monkeys of Holocene epoch. Its ancestors survived in ice age in relic forest islets and this way got an opportunity for the further evolution. In due course some descendants of this species had increased in size and had settled in ground habitats along the northern border of South American pampas and in Andes foothills. This primate inhabits tropical area of South America.
This species of primates considerably exceeds in sizes gorilla of human epoch. Length of this animal including tail is about 3 m, height at a shoulder of adult individual is up to 155 cm, weight of adult male is 300 kg, female – about 200 kg. As against an ancestor having dark colouring of wool, mapinguari has shaggy bright red fur. On back of adult individual wool is darker, on buttocks the naked sciatic callouses of blue color bordered by strip of black wool develop. The face of animal is hairless, skin is pigmented in great degree – usually it is brown though there are grey-faced individuals. Face is bordered from below by “beard” of white wool.
Tail is short – it has completely lost balance function, because only young mapinguaris can climb on trees. Adult individuals spend the whole life only on the ground. The top side of tail is covered with dark wool; bottom side is white. Raising tail, this monkey shows warning signals to congeners.
Fingers have the limited flexibility: thumb is not opposable, and the animal only picks up and tightens branches, using hands as hooks. Toes are short and joined together in common skin cover almost by halves. Usually mapinguari moves on four limbs, but during the feeding it rises on legs. This species eats leaves and young shoots of trees, and also nuts and other firm fruits. Teeth of this species are large and wide, adapted to chewing. Canines also are short, and due to this feature lower jaw can move in sides.
Mapinguaris live solitarily or in small groups. Single individuals usually are old animal, doing not wish to leave from places, rich in food. Adult individuals live in family groups including male and one or two females with cubs. Animals from different groups are not aggressive relatively to each other and frequently feed in common. Borders of territory of each family group are very indistinct.
Usually mapinguari is silent; animals communicate with each other with the help of rumbling and hooting. Threatening the opponent, this monkey utters loud throat growl, and call of alarm is loud long squeal. Using such cry mapinguaris warn of their detection of large predators – raptor cats or jagueira.
In breeding of this species the certain cyclicity is expressed. Courtship period takes place in the beginning of dry season. At this time males arrange ritual combats for females – they growl, push each other and strike impacts by edge of palm on each other’s shoulders. Such duels do not result in fatal outcome, but allow establishing of domination relations in struggle for the female. If the structure of family group is rather constant, male shows to females the favour, allowing them stealing his food, and shows force, snatching with noise and cries to other animals. Thus he only tries to frighten them, but does not attack really.
Pregnancy lasts till about 9 months, one cub is usually born. Twins represent a rarity – one case for some tens of deliveries. Within five months cub eats milk, but already at the second month of life it starts to try food of adult individuals. Till four years young individuals live with mother, but then they are expelled by her from group. Soon after that the female is ready to pairing again. Sexual maturity comes at the age of 6 years. Life expectancy does not exceed 50 years.

Colash (Volaticocebus colash)
Order: Primates (Primates)
Family: Sakis (Pitheciidae)

Habitat: South America, secondary tropical forests.
In the human era, titi monkeys were the most affected among the New World primates of the saki family. The number of most of them had been depleted by hunting and deforestation, and the species that survived the Holocene were severely affected during the Ice Age, when the area of tropical forests was reduced to some “islets” – refugiums for tropical fauna and flora. By the time the vast expanses of the jungle were restored, only 3-4 of the most common species of titi monkeys had survived, having restored the former diversity of the genus only partially. Among other groups of South American mammals, many enemies and competitors appeared at them, so the evolution of some descendants of these primates has gone in an unusual direction. Kolash is a descendant of the red titi monkey (Callicebus cupreus), which displays this kind of “step aside” in the evolution of New World monkeys. This species inhabits secondary forests on the plains of South America, occasionally entering primary rainforests, mainly in areas crossed by rivers.
This species has an expressed sexual dimorphism in its body size: body length is up to 61.5 cm in males and 57.6 cm in females. The weight of the male is about 11.4 kg; the weight of the female is up to 8.5 kg. Wool color varies in different populations: from dark ochre-red to black with a red ring around the eyes. The lower part of the muzzle (nose and mouth) is hairless, covered with dark gray skin. Eyes are large, of brown color. Ears are dark gray, slightly protruding from the fur. Its forearms are lined with bright red long hair. The structure of the forelimbs is unusual: on them, the distal end of the humerus extends from the elbow joint with an elastic cartilaginous rod, which is about half the length of the forearm. Between this rod, shoulder, side and the base of the animal’s thigh, a patagium is stretched, which is similar to the patagium of flying lemur (Microsifaka volans) from Madagascar – but much larger in area. Thanks to it, kolash can glide up to 50 meters in one jump, crossing by air even small lakes and rivers. Hence the name of the animal: Kolash is the Inca deity of the “essence of things”, born from a bird. The monkey’s hind legs are powerful, allowing it to make powerful pushes from the support, which are then replaced by a gliding jump. The forelimbs are very tenacious, and when they come into contact with the support, they almost automatically contract in a death grip, providing the beast with a secure hold on the support at the end of the jump. This species prefers landscapes, where areas of tall stands alternate with young stunted forest – such an area is favorable for gliding jumps.
The diet of this species consists mainly of leaves, and kolash prefers young ones from the tips of the branches. Less often, it eats flowers, fruits, and seeds, supplementing its diet with invertebrates. Kolashes live in small groups of 3 to 15 individuals – a male, two females and their cubs of various ages. There are groups of adolescent males who stick together and wait for the opportunity to take away other male’s females. Kolashes are most active in the morning and evening, giving signals to each other by calling at this time. In everyday life, animals use more than a dozen sound signals, and the cubs learn their meaning from adults. During the hottest time of the day, they relax and do grooming. Natural enemies of kolash are snakes and birds of prey, and arboreal predatory mammals are dangerous to the cubs.
Reproduction of this species occurs almost all year round, and in each group there are always cubs of various ages. Young animals differ from adult animals by having a lighter wool. Pregnancy lasts an average of 158 days, and the interval between births is 16-22 months, depending on the amount of food in the territory of the group. Usually a female gives birth to one cub, twins are very rare. Newborn cubs are completely dependent on their mother, cling to her immediately after birth and can stay on their mother’s body during a gliding jump. Later, the cub moves to the mother’s back. Other females in the group can also take care of the cub. Males are usually not interested in cubs until they are four or five weeks old. After that, the male can temporarily carry the cub on his back and take care of it, mainly to increase his social status. At the age of eight to nine weeks, the cubs begin to eat solid food, and by the age of six months they are weaned from their mother’s milk. At 1.5 years of age, upon reaching maturity, young males leave the parent group, joining the bachelors roaming the rainforest. At the age of 3, they already conquer the harem from the old male, or take young females away from family groups, sometimes by force. Life expectancy is up to 30 years.

Ghost monkey (Xenomyrikina spectrum)
Order: Primates (Primates)
Family: Night monkeys (Aotidae)

Habitat: montane forests of the northern regions of South America.

Picture by Alexey Tatarinov

South American monkeys of the human era were represented entirely or predominantly by arboreal forms, which made them dependent on the prosperous existence of forests. At the end of the human epoch, the situation changed for the worse for them: the forests were largely cut down and only small isolated areas remained from the once continuous massifs stretching continuously for tens and hundreds of kilometers. During the Ice Age, the remnants of tropical rainforests retreated to the banks of large rivers, surrounded by secondary forests or croplands. As a result, many species of New World monkeys became extinct, and the survivors (mostly small and less specialized species) have been preserved as small populations in relict “islands” of forest vegetation. Among the survivors were the night monkeys, or douroucoulis (Aotus), preserved in the remains of remote mountain forests. A descendant of one of the species of this genus is ghost monkey, one of the unusual monkeys of the Neocene forests of South America.
This species is a relatively large arboreal primate: body length is 85-90 cm; weight is 9-9.5 kg. The body is slender; the limbs are mobile and strong, moderately long. Hind legs are slightly longer than the front ones, digits on all paws are tenacious, but the thumb is not opposable. Head is round, with a convex muzzle and very large eyes: this animal is nocturnal. Eyes sparkle red in the moonlight due to the well-developed tapetum, which provides sharp night vision. However, ghost monkey does not distinguish colors well, although it can be compared with cats in terms of clarity of night vision. It also has acute hearing and a relatively good sense of smell: its nasal cavities are enlarged, and the olfactory epithelium forms numerous folds. The auricles are small, but the monkey has a movable neck and easily determines the direction of the sound source.
Wool coloration of this species is pale gray, the back and tail are darker, and the tip of the tail is white. Face is also covered with short white hair, and males grow mustaches and tufts of hair on their cheeks.
Ghost monkey lives in family groups of 2-5 adults; each group owns an area of up to 20 hectares. The members of the group communicate using a large number of sound signals, as well as using tail positions: monkeys can clearly distinguish the white tips of their relatives’ tails in the dark. In this species, tail is not prehensile, but serves as a balancer when moving on trees and as a means of communication with relatives. The animals spend the day in a shelter, usually in a large tree-trunk hollow, changing it every next day. If there is no hollow, the animals build a primitive spherical nest by bending and intertwining tree branches. This skill is acquired; the young learn from their parents and gradually become involved in building nests. Various groups have their own construction techniques and favorite types of trees for sleeping. At sunset, the group leaves its shelter and notifies the neighbors of their right to the territory with loud and long-drawn calls. The group marks the territory with urine; to do this, the animals urinate alternately on both soles, after which odorous traces remain on the bark of the tree for a long time.
These primates feed mainly on leaves and fruits, although they add arthropods and bird eggs to their diet. Edible plants are distinguished by smell, and the ghost monkey catches small animals by ear. This species lives exclusively in trees, moves in the crowns mainly with dexterous and accurate jumps, sometimes 9-10 meters long, although more often it moves from one tree to another using the lianas.
The breeding season lasts from August to November. Pregnancy lasts about five months. Usually there is a single dominant male in the group, although the dominant female stands above him in the hierarchy. Males quarrel quite loudly over females, but it usually doesn’t come to a fight. This happens if an alien male claims a female. Usually, the mother and her daughters, as well as the sisters, remain in their group, and the young males move from one group to another. Only sibling females of close age leave the group sometimes. Most often, a female gives birth to a single cub, twins are extremely rare. Breastfeeding lasts up to 6 months, but already a two-month-old cub tastes chewed food from the mother’s mouth and remembers some edible fruits. At this time, the childless females of the group also take great care of it. At one year of age, the juvenile is already independent and is trying to gain a place in the hierarchy. At the age of two, young males leave their parent groups and lead a solitary life for a while or form bachelor groups. Sexual maturity comes at 3 years of age; by this time, young ghost monkeys start a family. Life expectancy is about 30 years.

Kong (Titanosimia kong)
Order: Primates (Primates)
Family: Para-apes (Parapongidae)

Habitat: Jakarta Coast, South-East Asia, tropical forests.

Picture by Eugeny Hontor

In late Cenozoic apes were the largest primates. Growth of largest of them, Pleistocene Gigantopithecus, was estimated at 3 meters. At Madagascar, however, lemurs of genus Megaladapis approximately equal to gorilla in size lived. In human epoch large species of primates had suffered serious damage from economic activity of people and direct chasing. Giant lemurs, undoubtedly, had died out in early historical epoch because of hunting for them. Gorillas and other apes became rarity because of hunting and destruction of habitats. Their populations kept to the end of human epoch in some reserves, appeared too small in order to restore these species. No one species of apes had lived up to Neocene. But in Southern Asia evolution prepared the replacement to extinct large primates. The descendant of one macaque (Macaca) species had passed to ground habit of life and began the settling in all suitable habitats in tropical zone of Southern and South-Eastern Asia. In tropical forests of South-Eastern Asia and at the Jacarta Coast peninsula kong, the largest of ever living primates, had evolved. Weight of adult male of this species exceeds 700 kg, and his growth reaches 4 meters. The female of this species is smaller – her weight is about 450 kg at growth up to 3 meters.
Kong is an ecological analogue of Pleistocene ground sloths of South America and chalicotheres of Old World. It is too massive to climb on trees, and is exclusively ground species. Only young individuals are able to climb on trees. By constitution kong is similar to gorilla – this primate has very long arms, and back is inclined. Tail is not present at this species.
Living in twilight of underbrush, these primates are compelled to use very appreciable color spots to distinguish relatives. Sciatic callouses of kong are colored bright red and bordered by contrast ring of white wool. Sexual dimorphism is expressed not only in size, but also in colouring – male has black wool with brownish shade, and female is reddish-brown. Additionally male has brightly colored face – white with bluish spots on cheeks. Face skin of females is grey. The male’s neck is decorated with magnificent white mane contrasting with the general colouring of body. At females wool on neck is only slightly lengthened and darker, than wool on the body.
Jaws of kong are short and wide. Canines at females are very short and consequently don’t prevent to lateral movements of jaws at chewing. At males canines are larger and more appreciable – they are used in courtship displays and during an establishment of domination relations. The diet of kong is diverse and includes mainly vegetable food. These primates easily pull out plants from the ground and chew their tubers and rhizomes by strong molars. The significant part of their diet is made of foliage of young trees. In order to reach it, these para-apes rise on rear legs and bend trunk and branches of trees to themselves. Kong likes to feed in shallow water of tropical rivers with soft aquatic vegetation.
The food of animal origin in diet of kong is presented mainly by carrion and the rests of prey of large predators. Kong differs in massive constitution and sluggishness, and therefore it is very bad hunter. Its prey includes very large invertebrates and sluggish reptiles – tortoise or snake insufficiently quick after nourishing dinner may easily get for dinner to this primate. This species can easily drive away predators from their prey, using huge force and superiority in strength.
Kong lives the small groups numbering no more than ten individuals. In group there is a well defined leader – it is large adult male. Also there are subdominants in group – one of senior sons of group leader, or male came from the side and showing loyalty to the leader and supporting him. As a rule, dominant male descends from other family, rather than females of group.
Kong breeds very slowly. Females turn able to give birth to cub at the age of about five or six years. Pregnancy lasts till about one year, and till next three years the cub depends on mother in many respects. The wool of newborn kong is bright rusty and darkens in course of time. It develops slowly enough, and can independently move on four paws only at the age of five months. The cub is fed with milk till about one year, and only since the tenth month of life starts to use vegetative forage for food. During the life the female of kong can bring up no more than five or six cubs. At this species of primates twins are frequently born – one case to approximately 10 – 12 births. Obviously, this is an adaptation permitting to increase rate of reproduction at these animals. These primates have well advanced parental instinct, and frequently the female, too old to give birth to its own cubs, helps young females to look after cubs, and even transports the cub to the back. Adult kong does not have enemies, and this primate has an opportunity to live up to 50 – 60 years.

Tibetan yeti (Yeti tibetianus)
Order: Primates (Primates)
Family: Para-apes (Parapongidae)

Habitat: Himalayas and Tibetan Plateau, mountain forests.

Picture by Pavel Volkov

Picture by Alexey Tatarinov

The most progressive primates, monkeys, in Neocene express the variety comparable to their variety in human epoch. Large apes had not survived up to Neocene, but their place in this epoch is occupied by large species descending from macaques (Macaca) of Holocene epoch, which represent the special parapongid family. Area of this family is limited to mainly Southern and South-Eastern Asia. Parapongids include kong (Titanosimia kong) – the largest Neocene species of primates, the inhabitant of tropical forests.
Area of primates is limited mainly to areas with sufficient duration of day. In human epoch a number of monkey species lived in mountains where these animals endured normally temperatures below zero. In Neocene one species of primates, Tibetan yeti, also settled in mountain areas of Central Asia. This monkey is named so because of significant similarity to mysterious “yeti” in appearance and behaviour.
Because it is cold enough in mountains of Central Asia, Tibetan yeti is large creature: weight of adult male makes about 70 kg, female is smaller – up to 50 kg. Body of this primate is covered with rich wool due to what it is not afraid of severe mountain winds. For additional insulation at Tibetan yeti all projecting parts of body – ears, face and limbs – are rather short. In comparison with its close relatives from tropical forests Tibetan yeti looks rather thickset creature. Primates from warm habitats often have sites of hairless skin on face, breast and in genital area. This skin is frequently bright colored and serves for demonstration during the communication and establishment of domination relations. In cold mountain climate at intensive solar radiation Tibetan yeti has a minimum of naked skin on face and body – the whole muzzle of this monkey is covered with short, but rich wool; wool grows even on ears from external side. The back side of feet and hands, and also fingers and toes from above are also covered with wool. Perhaps, only lips and eyelids are not protected by wool.
For protection against overcooling at this primate the extensive sciatic callouses formed of thick layer of cornificated skin are advanced. Due to such adaptation animal can sit on cold stones without harm for an organism. Soles are also covered with cornificated skin.
In mountains at high altitudes trees which could sustain weight of this monkey do not grow. Tibetan yeti has substantially lost skills of tree-climbing, and the structure of its feet had undergone significant changes. On foot of this monkey the big toe is short, and other toes are connected in the basis by soft tissues and had considerably lost mobility. Actually, only distal halves of toes, which are short in themselves, remain free. Tail of Tibetan yeti has not disappeared completely, but is considerably reduced. It keeps mobility, but is very short and covered with rich wool. Such tail can not be the balance weight at movement any more, but is quite functional as means of expression of emotions.
Male and female at this primate appreciably differ in colouring. The male’s wool has chestnut color with reddish shade, darker on back. At females wool is almost black. Male also has wide white “eyebrows”, white moustaches and short beard. Females have only small sites is white wool above eyes.
In mountains the nature does not give a rich choice of food, on contrary to tropical forest. Tibetan yeti is practically omnivorous: in summer its diet includes leaves and berries, and also insects and other invertebrates. In winter the nature of mountains is scanter, and from vegetative food in yeti’s diet buds and needles remain. But at any time of year small vertebrates and carrion make the desired additive to diet. Tibetan yeti frequently keeps eyes on birds – scavengers and predators like tanatos – and eats the rests of their prey.
In order to find enough amount of food it is necessary to be able to clamber on stones. In summer yeti moves on four limbs more often, like other monkeys. Winter snow and cold force it to move on hind legs, preserving hands from cold. During a bad weather yetis crowd together, closing cubs by bodies (such behaviour resembles the formation of “turtle” at penguins in human epoch), but search shelter in caves or among stones more often.
This primate survives in severe mountain conditions due to social way of life in many respects. It lives in small groups (up to 10 – 15 individuals), in which the strict patriarchy-based hierarchy reigns. In extreme conditions for preservation of group the survival rate of young growth is important. In connection to it at young animals well expressed juvenile colouring – reddish fur with dark face – develops and is kept till first two years of life (even after they become independent). Such colouring gives the cub the right of best piece of food and superfluous care from the side of adults. As it grows, colouring of young individual changes to adult one, and at other individuals in group other favourites appear. Young “adolescents” keep in group separately, and sometimes leave parental group together, keeping friendship for long years. Such individuals challenge authority of male from other group more successfully or simply entice females from his group to their own one.
Tibetan yetis grow mature for very long time – not less than seven years pass before a sexual maturity. First one and a half years young animal stays with mother, being trained at her to receptions of food search and skills of social behaviour. Life expectancy at this monkey is not less than 40 years. For this time the female has time to bring into the world and rear no more than ten cubs.

Almas (Yeti almas)
Order: Primates (Primates)
Family: Para-apes (Parapongidae)

Habitat: western Himalayas slopes, mountains of Central Asia, mountain forests and bush thickets.

Picture by Pavel Volkov

Almas is a close relative of Tibetan yeti, the monkey living in high-mountainous areas of Tibet and Himalayas. It belongs to parapongid family including mainly large Old World monkeys descending from macaques, but convergent similar to pongids and hominids extinct to Neocene. Almas differs considerably in ecology from yeti: it is more thermophilic and in mountains does not rise up to snow border and lives not above zones of deciduous forests and bushes. Also it is much smaller than yeti: adult almases weigh no more 50 kg (males) and 30 kg (females). As well as yeti, almas is covered with rich wool, but it has rusty brown color, lighter, than at its eastern relative; there are also grey color forms (up to 40 % of a population). The sexual dimorphism in colouring is expressed in presence of white spot on breast at males and darker general colouring of wool. At females head is lighter, rather than at males, and newborn cubs are covered with silver-gray wool. At grey color morph cubs are almost white. Juvenile colouring helps to moderate aggression of adult individuals during their games with cubs.
This monkey species moves mainly on four paws, but has ability to keep in biped pose for a long time, getting food with the help of hands. Feet are covered with thick corneous callouses from the bottom side due to which animal can move on stones. Big toe has kept mobility and helps animal to grip stones and tree branches. Other four toes have grown together in the basis and are less mobile, than at forest monkeys from tropics. Tail is short, but mobile.
Almas lives in family groups numbering 8 – 12 individuals: dominant male, 1 – 2 subdominant ones, sexually mature females and their cubs. These primates eat various kinds of food, but, as against yeti, almases differ in omnivorousity and willingly eat food of animal origin. They are capable to kill and to eat even rather large animal, do not disdain carrion, drive away predators from prey, and occasionally there are cases of cannibalism. Almases have kept more skills of tree-climbing, than yeti did, and can escape on tree in case of predator attack. The young growth swarms up trees especially good. Almases protected themselves against small enemies on manners of macaques and baboons: males show aggression and intention to fight, opening mouth and showing large canines while females and young growth escape far away.
The sexual maturity of almas comes at the age of 5 – 6 years. Once a year the female gives birth to 1 – 2 cubs. Newborn ones are helpless and only can grip for wool of mother. Therefore childless females of group frequently incur a significant part of care of cubs of other females. Life expectancy of almas is about 30 – 35 years.

Yeren (Yeti bambusiphagus)
Order: Primates (Primates)
Family: Parapongids (Parapongidae)

Habitat: mountain forests of China.

Picture by Pavel Volkov

During the human era, the diversity and range of great apes decreased significantly, and by the end of the human era, their scattered and small populations gradually died out. In Neocene Asia, representatives of a new Parapongidae family, which includes the largest primates on Earth, replaced the great apes. Parapongids occupied a variety of ecological niches; due to their large size, they managed to develop life in the cold high-altitude regions of the Himalayas.
The conditions in China’s mountain forests are much less harsh than in the Himalayas. Evergreen and semi-deciduous forests in the subtropical climate are home to another parapongid species – yeren – which is related to Tibetan yeti (Yeti tibethianus). It is adapted to inhabit milder climates and is found at lower altitudes where forests and shrubs grow.
Yeren is a large herbivorous monkey. The height of an adult male reaches 160 cm (weight up to 70 kg), the female – up to 120 cm (weight about 50 kg). In family relationships of yerens, polygamy prevails, although monogamous couples who raise offspring together are often found. Body is covered with thick brown hair. Skin on the face is bare; it is bright red in males and pink in females. The face is fringed with yellow fur, and the male has a thick beard and mustache. Individuals of both sexes have black “caps” on their heads. There are sciatic calluses on their buttocks, formed of thickened skin of a bright pink color. These monkeys are tailless.
Yeren moves on four limbs, which are of approximately equal length. During its feeding, this animal often takes a bipedal pose, reaching for leaves or bending tree branches. The thumb on the foot is significantly reduced, and the remaining toes are almost half connected by a skin tie. Yeren can climb trees, although its skills in it are worse than in small monkeys.
This monkey species feeds on bamboo and other herbaceous plants, as well as fruits and foliage of shrubs. When foraging, yeren exhibits some elements of tool activity – it uses sticks to dig out plant tubers. Yeren especially often eats juicy young bamboo shoots that just started their growth. The activity of these monkeys is a natural factor in thinning bamboo thickets. Rough food led to the development of the jaw apparatus and changes in skull shape. Yeren has large tubercular molars and very short canines, which allows it to chew food with lateral movements of the jaws. Jaw muscles are strong – the monkey easily cracks nuts with bites and chews bamboo stalks. In yeren males, skull has a distinct sagittal crest, to which muscles are attached, which makes their heads look a bit like a gorilla’s head in profile. Occasionally, yeren supplements its diet with food of animal origin – eggs and chicks of birds, insects and remnants of prey of local predators.
Yeren often lives in family groups under the male’s leadership. In such a group there are 2-4 adult females with cubs of various ages. Often the old male remains in a group headed by one of his sons, but is always in a subordinate position at one of the lowest places in the group hierarchy. Social ties between animals are very strong, and all members of the group stand up for the protection of the cub, regardless of the degree of kinship with it.
The breeding rate in yeren is very slow: the female gives birth to one cub every three years. The newborn cub is covered with light yellow fur, which darkens with age. Living in harsh conditions forces young animals to learn for a long time how to survive. It is only at the age of five that the young yeren becomes fully independent, and puberty begins at the age of about 7 years. Life expectancy is about 40 years.

Enkidou (Enkidou sylvaticus)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)
Habitat: Southern Asia, plain and foothill woods.

Disappearance or significant reduction of areas of tropical rainforests during the ice age had caused mass extinction of species connected to these biotopes. Among irrevocably missed animals there were large primates – apes. Gibbons, chimpansees, gorilla and orangutan have died out, not having left descendants. But small species of monkeys were in incomparably best position. Bieng ecologically plastic they have developed life in light forests of glacial epoch, and when woods again have covered tropical zone of Earth, wood inhabitants have appeared among them. Among new wood monkeys the special family of “false apes” including very large species descended from macacas and convergently similar to gorillas of Holocene epoch is especially remarkable. In some areas other large primates, descendants of langoors (Presbytis) widely settled in Asia, compete with them.
The enkidou named after beast-like hero of Sumer epos is huge primate similar to gorilla having short tail. It is the primate of massive constitution moving by the ground mainly on four paws, but sometimes rising on legs. In such position this monkey can make some steps, holding something in hands. Growth of the rising monkey reaches 3 meters. The body of animal is covered with shaggy black wool; face skin is naked, colored red. Brightly colored face is a mark of recognition by representatives of this species of neighbours. However the area of buttocks serves as not less important recognition symbol at these species, as well as at many species of monkeys. On buttocks of enkidou there are large sciatic callouses covered with naked lilac-blue skin at males and bluish-grey skin at females. These formations have also alarm function, by their appearance it is possible to determine approximately the status of individual in group, its physiological condition and readiness for pairing at female. Thus, sciatic callouses of this animal serve as its original “passport”.
Wool of cubs is colored differently, than at adults: they are light grey, almost white, with pink face. Sciatic callouses at them are covered with wool. Such distinctions in colouring have the important value: they serve as the deterrent for aggressive adult individuals, showing the “special status” of cub in group. For this reason all pranks and theft of meal at adult monkeys are forgiven to cubs, and the adult member of clan may have strong punishment for it.
At males of enkidou in mouth long canines used for demonstration at an establishment of hierarchy jut out. During fights between adults they are not applied, but at defense against predator or at rescue of the cub got to its claws adult males inflict terrible wounds by canines. At females canines are much shorter. Molars of enkidou are wide and knobby – the significant part of diet of this species include with coarse sappy vegetative food.
Because of massive constitution enkidous spend the most part of life on the ground though they can swarm up trees. Especially frequently cubs do it, finding in branches fruits inaccessible to massive adult individuals. This species of monkeys is omnivorous, equally willingly eating both vegetative food and meat (if it will be possible to find it). Enkidous willingly eat tubers and sweetish roots of ferns, soft leaves of bushes, fruits of different trees. The food of animal origin includes insects (especially they like juicy and fat larvae of beetles), bird eggs and nestlings, frogs and small mammals. Using the might and large number enkidous can take away catch of different predatory animals, or pick up rests of meals after them. During the meat sharing the severe hierarchy is observed: the dominant male with huge canines tries this dish first, choosing to itself best pieces. He personally endows with meat of females with which he is coupled, after them males with whom supports friendly relations more often, and further all cubs irrespective of whose are they. After that he leaves a carcass for individuals of the lowest rank and does not care of its sharing any more. Frequently lowest individuals in hierarchy get only uneatable pieces of skin and cartilages, and sometimes they get only smell of meat. If someone from animals of the lowest rank tries to steal a piece of meat out of turn, the true fight accompanied with loud roar and menacing grimaces can be fastened. At this time any monkey does not try to steal meat from fear to get “in the heat of the moment” to the prepotent male. It happens that in an impulse of anger the male inflicts to members of clan traumas and mutilations by impacts of powerful hands.
The sharing of vegetative food never happen such noisy and strict because usually it is enough of it for all ones. However dominant males watch closely members of clan being always ready to take away from them something tasty, that they have to found and had not time to hide and to have eaten. At the same time the leader strictly watches that anybody, especially youngsters, did not take away meal from cubs. Caring about cubs, the dominant male strengthens his social status in clan - a lot of females will want to be coupled to him and will support him if there will be any threat of leadership change in clan.
But the dominant male should fulfil such privileges to the full: at an attack of predators or at conflict with the next clan he acts in the forefront among defenders, and at times outcome of the conflict depends on his behaviour.
Time of pairing at enkidou is stretched for half-year falling to rainseason. At the female ready to pairing sciatic callouses increase and become bright blue. Usually each male occupying high enough position in clan has one female to which he couples regularly and supports friendly relations during all life. The female from such steady pair even can abandon clan together with the male when the readiness for pairing comes, spending some days at some distance from the basic group of clan.
Pregnancy at these species of monkeys lasts about half-year. The newborn cub is covered with wool, at it eyes are opened, and it practically at once can move head and grip for wool of mother. First time mother constantly carries the cub at breast. Later it gets over to her back. At bi-monthly age cub climbs down from mother and starts to play with coevals, at three-monthly age it starts to try food of adult animals. Half year old cub ceases to suck milk and starts to spend more time on the ground, moving together with adults. At one-year-old age the wool of the cub starts to darken: it starts to mature and turns to the “teenager”. At this time it usually receives the first punishment from adult animals that marks the ending of the carefree childhood. But connection between young animal and its mother is kept for long years, even when the female has other cub. At the age of three years the young female is ready to give rise to first cub.
Life expectancy at enkidou is 40-50 years. For this time up to 6-7 cubs can be born at the female.

Sugriva (Pachypresbytis sugriva)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: Hindustan, South Asia, forests of various types.

Female

Picture by Pavel Volkov

Most primate species suffered greatly during the human era: habitat disturbance and hunting led to a severe decline in numbers and the extinction of a number of species. On the contrary, some monkey species that have adapted to life next to humans have gained a significant survival advantage by maintaining a high population. Among them was the Hanuman (sacred) langur (Presbytis entellus), an inhabitant of South Asia. In Neocene, several monkey species, leading various lifestyles, evolved from it, including quite large ones.
One of descendants of sacred langur is sugriva, a large herbivorous monkey from the forests of South Asia. It has a brightly expressed sexual dimorphism: the height of the male at the shoulders is about 1.5 m at a weight of 140-145 kg, the height of the female is up to 1 m at a weight of about 100 kg. This primate moves almost exclusively on all fours, sitting on well-developed sciatic calluses for feeding. In terms of lifestyle, this species is an ecological analogue of the gorilla, but differs from it in its physique: the limbs are approximately the same length, so the animal’s back is not sloping. It also has a relatively short tail (less than half the length of its body). This is a legacy left over from its long-tailed ancestor, but the tail of this species is no longer used as a balancer: due to its massive build, sugriva moves relatively slowly along the branches without jumping. This monkey only needs a tail to express its mood. Sugriva cub uses its mother’s tail as a support when moving on branches, holding on to it with one hand.
The coloration of the wool of sugriva is quite contrasting: large white and black zones all over the body. The main version of coloration includes black body, white chest and belly, and white hair on the head. Often head is entirely white, less often crown and nape are covered with black hair. Skin on the face is hairless and yellowish. The sugriva male is not only larger than the female, but also has a “collar” of elongated black hair growing on his neck, the development of which is determined by the influence of hormones. The size and splendor of the “collar” depend on the age of the male and his social status. The cubs have single-colored bright ochre-red wool. As the young animal grows, red color of its wool gradually brightens or turns brown, and the animal gradually gets the black-and-white coloration characteristic for adults.
Sugriva leads a predominantly arboreal lifestyle. This monkey stays on large branches of trees, mainly ficus trees. If necessary, the animals can easily descend to the ground and move to other areas of the forest. This species feeds mainly on ficus leaves and other fibrous and difficult-to-digest vegetation; due to this, sugriva avoids competition with other herbivorous mammals. The canines of this species are very short: processing such food requires prolonged chewing with the help of lateral movements of the jaws, which would be hindered by too long canines. Head of sugriva bears some resemblance to the head of a gorilla due to the presence of a parietal crest, to which strong chewing muscles are attached.
The chewed leaves are digested in a large specialized stomach: they are fermented in one chamber (which is why monkeys have abundant and frequent belching) and digested in two others, located sequentially after each other. The intestines are very long, which is why monkeys of this species have a large belly. During feeding, monkeys just sit in a place and pull branches, the leaves of which they cannot reach, towards themselves. As a result, each individual chews off the branches around itself. In order not to deplete food resources, animals have to move to another tree. Sugrivas usually do not stay in a certain area of the forest for more than 2-3 days.
The mating season of this species is extended throughout the year, with only some seasonality observed on the northern border of the range, at the foothills of the Himalayas, where the greatest mating activity occurs in the autumn months. Pregnancy lasts 7 months. The rate of reproduction is relatively slow, which is typical for large monkeys in general. The female gives birth to one cub every 4 years. The cub spends the first 8 months on the mother’s back, holding tightly to her fur. The cub feeds on milk for the first year of life, but since the age of 4-5 months it begins to taste adult food a little. The young animal reaches independence by about 5 years of age; at this time, the mother already has the next cub. Puberty begins at the age of seven. In young males, the hair on the throat darkens from the age of 5, and by maturity a ring of elongated black hair is formed.
Due to the abundance of food, this species is not territorial and does not show aggression towards its relatives: 2-3 animals can feed freely on the same tree.
Males are aggressive towards each other only in the presence of females who are ready to mate. But even then, it is expressed most often only in loud calls (hoots). It is only when competition escalates that displays are launched: males measure their height when standing up on two legs, and can shake branches.
The life expectancy of this species reaches 38-40 years.

Kappa (Potamopithecia kappa)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: rivers, lakes and swamps of Japan Islands, mainly in eastern part of archipelago.
Primates almost never passed to completely aquatic way of life. Anyway, among them there were no animals as closely connected to aquatic environment, as otters and pinnipeds among carnivores or hippopotamuses and sirenians among ungulates. Separate species of primates of Holocene epoch were connected to aquatic environment only in part: these ones were Allen’s swamp monkeys (Allenopithecus) from Africa and long-nosed monkeys (Nasalis) from Southeast Asia. Among monkeys of New World there were at all no species adapted to existence in water or near water. One more primate right in human epoch had shown obvious propensity to life in water. This event took place in Japan Islands, where some populations of Japanese macaques (Macaca fuscata) passed to life in water in part. Island isolation promoted to evolution of their descendant into very special creature – to the species of Neocene primates most adapted to life in water.
In Japanese legends the fantastic water creature, kappa, is mentioned. According to legendary descriptions, kappa is similar partly to human being and frog simultaneously, and differs in rather blood-thirsting inclination. In Neocene in the native land of legendary kappa the monkey, became literally a material embodiment of this creature, certainly, with the exception of some magic properties and predatory bents, had evolved. Therefore aquatic primate from Japan Islands is also named kappa.
Habitat of Japanese kappa includes banks of water bodies, rivers and lakes, thickets of coastal vegetation. Kappa avoids life in rapid and cool mountain rivers, preferring warm and rather slowly current water bodies, which banks are overgrown with forest and bush. Especially numerous populations of kappa inhabit eastern side of Japan Islands directed to ocean. Obviously, there it was a centre of kappa speciation.
Appearance of kappa is very remarkable – animal combines attributes of tree-climbing and aquatic animal. When kappa swims, rear limbs are principal organs of movement. Feet of this primate are adapted to swimming: they are rather long and wide, and between toes rudimentary palamas grow. Big toe is considerably reduced. With the help of such feet kappa swims in water quickly, resembling a huge frog at this moment, and also walks on fenny ground. Unique feature of this monkey is ability to walk on rear legs for more or less long time. It amplifies the similarity of Japanese kappa to its legendary prototype even more. Kappa differs from human beings in hunched bearing – backbone of this primate is slightly curved, and does not form S-shaped shock-absorbing bends. Moreover, feet of kappa are not vaulted as human feet are, and do not spring at walking. But they are adapted very much for walking on soft ground.
On temples, head sides and nape of kappa long dark hair grow. This is very useful adaptation – the cub keeps for them, sitting on back of the female. But on top of monkey’s head hair are short. On body wool is also short and thin, yellowish-brown in color. Skin on kappa’s face is naked and rather brightly colored: at males face is dark red, and pink at females. Male differs from female also in wool colouring: at his breast dark wool grows, whereas at female wool on breast is bright yellow. Moreover male has much longer and richier “whiskers” growing down to the middle of breast. Male is 20 – 25 % heavier than female and differs in larger jaws with long canines.
Kappa lacks of tail – it had disappeared at far ancestors of this species. But at animals of both genders bright sciatic callouses are advanced. At males they are light pink, not too visible on the background of wool. At females sciatic callouses are bright red, shaded in addition with black wool on buttocks. This deliberately bright colouring is connected to social behaviour of primates in which the condition and demonstration of sciatic callouses and area surrounding them has great importance. This is a powerful gesture of suppression of aggression, which is important for this species – kappa males are rather aggressive, and among them the strict hierarchy is supported.
Arms of kappa are about the same length, as legs are. Kappa’s hands have long sensitive fingers – they are equally well adapted to grasping of tree branches when animal climbs and to searching for small invertebrates in muddy water – kappa frequently searches for food under water to the touch. When kappa swims, it presses hands to breast.
Kappa has also other adaptations to aquatic habit of life: when animal dives, its nostrils close. At diving kappa can hold the breath for one minute and more. Under water kappa searches for food – roots and tubers of aquatic plants, snails, crustaceans and frogs. Gathering trees fruits drop in water, kappa keeps in water in upright pose, standing on rear legs. In this case wide feet prevent sticking in oozy bottom. Diving skill belongs to the number of acquired attributes; therefore kappa with very young cub appears very vulnerable. The only way of rescue for such female is its skill of tree climbing – kappa had not lost this ability though does it worse than other monkeys because of feet specialization. But the female has got in a trouble, can expect to the aid of relatives: having gathered in group, kappas can counterattack a predator. Males may be especially dangerous to aggressor – attacking it, they put deep wounds by canines.
Kappa female gives birth to one cub once a year; the expressed seasonal prevalence in breeding of these monkeys is absent. Cub differs in colouring from adult individuals: it has light grey wool and pink skin on face. As it grows, the wool of young individual changes colouring: first it becomes plain yellowish, and then starts turning darken.
Kappas spend a lot of time in games with each other and both cubs, and adult individuals equally like to play. Animals conceive games not only on trees, but also in water. Jumps in water represent the especially favourite game at young kappas. Monkeys jump in water from height, having swinged on flexible tree branches. Each group of kappas has favourite “game tree” on which animals swing with pleasure when the group of animals comes back to this place.
Approximately at the age of eight months at young kappa long hair on head start to grow. Individual development is rather long – the young animal keeps connection with parents even after birth of the next cub. Young kappa becomes completely independent approximately at two-year-old age. At this time young females study to care of posterity, helping mother to look after their own younger brothers and sisters. Females become capable to breeding at the age of three years, males – for half-year later.
Like all primates, kappas are social animals. They live in groups including several breeding couples and their posterity. As a rule, adult animals are joined by consanguinty, but the significant part of group can be submitted by individuals from other populations. Young kappas live for a long time in parental group – females more often remain in it till whole their life, but males in most cases pass to other groups. If male stays in parental group, his social status will be low while his father is alive.
Kappa lives in groups, differs in ability to bipedal moving, and its hands allow manipulating with small subjects. But it does not mean an opportunity of intelligence development for them at all. These monkeys do not make tools, and their brain is rather small. In addition to it this species is closely connected to specific habitats – humid marshy forests. Populations of kappa contact among themselves rather poorly, and in each population differences in appearance of animals, and even in size, from other populations quickly accumulate.
Kappas evolved at the islands, in area isolated from continent. Ways to distribution for them are cut off by wide sea passages. Kappa is able to swim, but salt sea water makes passages completely insuperable obstacle for this primate. Therefore kappa appears only very specialized kind of monkeys; it does not have prospects for development of intelligence, and has no one opportunity to settle beyond Japan Islands.

Satori (Montanopithecia satori)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: mountains of Japan Islands.
The moment of the change of epochs and the onset of Neocene was a time of great opportunities for those species of animals and plants that survived the human era and survived the subsequent climatic changes. With the termination of the human age, many animal families had become extinct, especially of large ones, including the great apes. The ecological niche of the great apes had been empty not for long: some small monkeys began to increase in size rapidly, and soon new primates appeared in the world – parapongids, a new family of primates that did not exist before, evolved in Asia. But among the groups of Old World monkeys existed earlier, new species have also appeared, which are not inferior in size to the great apes. This happened in the relatively isolated world of Japan Archipelago, where the parapongids from mainland Asia had not settled. Large kappa inhabits rivers, lakes and swamps of Japan Islands, and a closely related species, satori, named after the Japanese equivalent of the yeti, lives in the mountainous areas of the archipelago.
Satori is a medium-sized monkey, about one meter tall in a bipedal position. It is tailless, but with strong and tenacious paws, hind and front, which makes it convergently similar to great apes. This species can move not only on four, but also on two legs, freeing its fingers to gather food. The hind legs are slightly longer and stronger than the forelegs – satori is also a good jumper; it has well-developed binocular vision, as well as hearing. Adults are covered with reddish or brown hair, and by winter a thick undercoat also grows. There are only few hairless skin areas on the animal’s body: sciatic calluses and the upper side of the feet and hands are covered with hair, and there are hairless areas on the face only around the eyes, nose, and mouth. Thick dark fur grows on the outside of the ears.
Satori is a sociable monkey living in groups with a clearly expressed hierarchy. At the head of each group is the leader, the other monkeys are his wives and children, plus several subordinate males, which periodically try to displace the leader, but in case of danger they take an active part in protecting the offspring. Male differs from female in its larger size and greater weight. Large canines grow in his mouth, which are displayed to aggressors, and the fur on his ears forms lush tufts. During fights, monkeys drag each other by this hair, so the hair on the ears of the weakest individuals is pulled out. The skin on the male’s face is dark pink, and it turns very red during agitation and irritation. In females, the skin on the face is usually pale pink and becomes brighter during the mating season. Cubs are covered with black fur, and the skin on the face, palms and feet is grayish-white – this coloration serves to suppress aggression in adults. Social ties are maintained by mutual grooming and joint games with the young.
With the onset of puberty (at the age of about 3 years in females, 4 years in males), young satoris leave their former family and go to search for a new one, thus avoiding inbreeding and increased competition.
Predators of satori are local birds of prey and carnivores that attack mostly young monkeys, avoiding contact with numerous groups. They most often attack teenagers searching for new families and unwary youngsters; monkeys also die from winter starvation and mountain collapses. Adults of this species have actually no enemies. The average life expectancy of satori is up to 30 years.

Healer monkey (Micropresbytis medicus)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: Southern Asia, tropical forests and bushes.

Picture by Lambert

In Neocene the primates order is presented by a plenty of species of monkeys and prosimians. At the boundary of Holocene and Neocene hunting, destruction of habitats and climate changes had resulted in reduction of number and specific variety of primates. Warmer climate of Neocene has resulted in expansion of territories suitable for life of primates, and their variety began to grow again. Among them very original and specialized species had evolved.
Mountain ridges separated Eurasia into two sharply differing worlds: cold north with obviously expressed change of seasons, and humid tropical south. To the south of mountain zone, in tropics of India and Indochina, fauna is very rich. Forests and bushes are populated with various large ungulated on which the set of species of parasitic invertebrates lives. Usually the role of their cleaners is carried out by birds, but in tropics of Asia small species of monkeys evolved, which also specializes in gathering of parasites from wool of these animals. Such behaviour is derivate of grooming, usual behavioural feature of monkeys. Birds clear herbivores of parasites on open areas, and monkeys do the same in forests. Due to such division they do not compete to each other.
Healer monkey living in tropical forests and woodlands is a small species of primates. It is larger than squirrel guenons living in Africa: weight of adult male is about 700 grammes, female is up to 500 grammes. At this species of monkeys there is very bright and appreciable colouring. The basic background is bright red, stomach and forepaws are white. Skin on face, palms and feet is dark and hairless. In addition to size males differ from females only in presence of small “beard” and longer canines. At females canines are only a little longer than other teeth.
These primates live in small family groups numbering from one up to three males, up to five females and their cubs. In group the strict hierarchy is supported. Animals communicate with each other by means of various sounds; in “language” of healer monkey there is about 20 various signals.
Usually monkeys keep on trees and among bushes, but spend a lot of time on the ground. Usually they move in forest, keeping nearby from large herbivorous mammals. It is connected to features of behaviour of this primate species. Healer monkey is omnivorous and willingly eats fruits of various trees. When monkeys are fed, they drop a part of fruits on the ground, and it additionally involves ground animals. But the significant part of a diet of healer monkey is made with various insects and other invertebrates gathering on bodies of herbivorous mammals. Monkeys get on backs of animals and clear their wool of parasites, in exchange receiving the additional protection against predators. Due to contrast colouring they are easily found out by herbivorous mammals which behave quietly at the presence of monkeys. Animals get one more advantage from the neighbourhood with monkeys: these primates have good sight and beforehand warn animals cleared by them of approach of predator by loud cries.
At the watering place these monkeys prefer to keep near large mammals which presence frightens off snakes frequently attacking animals of this species. Besides snakes, the main enemies of these primates are large birds of prey and small mammalian predators.
These primates breed quickly enough - approximately in half of cases at the female twins are born. Cubs are looked after by all females of group due to what the survival rate of posterity is very high. The young monkey becomes capable to breeding at the age of three years.

The idea about existence of this species of mammals was proposed by Momus, the forum member.

Jumping squirrel guenon (Sciuropithecus semivolans)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: tropical woods of the Central Africa, highest trees.
At the end of Holocene tropical rainforests of equatorial zone of Earth have had not best time: aridization and the cold of planet climate during the ice age has sharply reduced their areas, having caused disintegration of earler uniform zone of woods to the set of small islands. Representatives of fauna of these natural communities have died out or their number was sharply reduced. But some species used original strategy of survival which had helped to stay number of species at former level: they have simply decreased the size and at the reduced territory of woods the big population which survival is more stable could live. Elephants and rhinoceroses from islands of Mediterranean Sea, mammoths of Wrangel Island and Columbian elephants of islands near coast North America had used this strategy in Pleistocene. And in forests of Africa guenons (Cercopithecus) have acted so. One of species of these motley monkeys had turned to real dwarf in its genus that has permitted to it to survive. And this tactics had appeared so successful, that later this species had evolved into some affiliated species occupying different ecological niches. So the genus of squirrel guenons (Sciuropithecus) which representatives practically do not exceed the common squirrel by size had appeared on Earth. After increase of the forest area species of this genus were settled widely, but the inhabiting at different “islands” of forest had resulted in formation of different species distinguished from each other by behaviour and habit of life.
Squirrel guenons are very “large-headed” in comparison with other species of monkeys – it is common feature of all small primates including South-American marmosets (Callitrix) to which squirrel guenons are similar by ecology. Besides these tiny primates differ from each other by numerous “ornaments” of hair, color strips and spots serving for specific recognition.
Jumping squirrel guenon is the typical representative of genus. It lives on highest trees of tropical wood and has the original adaptation for such life. This monkey is the excellent hopper; at it has big hinder legs with tenacious long toes. It easily surmounts distance of ten meters and more by jump. For small creature it is a simple task: the monkey keeps in air due to long hair growing on sides and shoulders forming original “parachute”. The magnificent hairy brush on the tip of long tail helps to drive in flight. By it the jumping squirrel guenon is convergently similar to monkeys of guereza genus (Colobus). Pushing off from branch by legs, monkey stretches hands in sides and freely soars in air, supported by ascending air streams. Having reached up to the planned branch, it bends body, extends legs forward, deflects head back, and seizes bark by toes. Due to abilities to “fly” it practically has no competitors among neighbours, having mastered life on highest trees of tropical forest.
The jumping squirrel guenon is colored contrastly: almost all body is covered with white wool, hairs of “parachute” are white too, and on back there is black longitudinal strip expanded on shoulders. At males faces are covered with bluish naked skin and have red “sidewhiskers” and beard, at females skin on the face is pink and hair “ornaments” are not present. Besides at males of this species long canines are advanced. Cubs sharply differ in colouring from adults: they are covered with brown wool brightening later.
These monkeys keep in crones of the highest trees (at height over 30 meters) in flights of 20 – 30 individuals. In group the main pair is precisely appreciable, and other pairs implicitly submit to them. In rear guard of the group there are young not sexual matured individuals and bachelors. They are afraid of leader, and at the same time regularly challenge his right on leadership.
At these animals the “language” of sound signals is advanced including up to 30 various “words” like squeal, hoot, twitterling and cries.
Jumping squirrel guenons eat soft fruits, seeds with thin covers, both various insects and spiders finding them in tree crones. They do not compete to wood rodents specialized in feeding by firm forages. Besides squirrel guenons are rather aggressive to them, and rodents, as a rule, avoid places where these primates keep.
The female gives rise to one cub once of times 5 – 6 months. First time it grips for wool on her breast, later gets over on mother’s back. While at the cub “child's” colouring is kept, all individuals in flight irrespective of rank willingly play with it. But later, approximately at four-monthly age, colouring starts to brighten: the cub matures. It finally leaves mother at the age of seven - eight months though from time to time it communicates with her during all life. The grown up young growth keeps aloof of the leader seeing threat to the leadership in bachelors. To prove the right of domination the male resorts to menacing demonstrations: he opens a mouth wide, showing sharp canines, and squeals shrilly. Thus he shows the force, jumping in branches or shaking branch on which it is sitting. Usually such reminders on leadership are bloodless and are limited only to demonstrations but if the opponent is audacious and is not going to submit, demonstration of forces passes in fight, being accompanied by bites and peces of pulled out wool. When the hierarchy is indisputable, the group can food peacefully, except for moments when the individual lowest by rank does not succeed to hide a lucky find from vigilant look of the clan leader. Social connections in clan become stronger with the help of grooming. Squirrel guenons as however all monkeys express this way the loyalty or favour to the neighbour.
As well as all small animals squirrel guenons live not so long though due to the brain size they can be considered as long-livers in comparison, for example, with rodents: they live up to 10 – 13 years.
Representatives of closely related species living in forests of Equatorial Africa are:
Marsh squirrel guenon (Sciuropithecus paludiphylus). This primate belongs to the same genus as previous one. It differs from jumping squirrel guenon in more massive constitution, shorter extremities, absence of hair fringe on sides and also in other wool coloring. Colouring of this species is much darker: head of black color, grey back and white stomach. Along sides longitudinal rusty-brown strips spread, on hands there are “gloves” of red wool. Around of eyes this monkey has rounded sites of naked white colored skin. It is the frightening colouring which is making an impression of huge unblinking “eyes” of any large animal. Cubs have no such false “eyes”, and they do not have sites of red wool on the body. Tail at monkeys of this species is covered with black wool with white hairy brush on the tip.
This species of monkeys is larger rather than jumping squirrel guenon: adult monkey is young cat-sizeed and male is larger than female. Living in marshy woods marsh squirrel guenon frequently searches for food near to water: it is able to catch crabs and tadpoles in wood pools. Also these monkeys are willingly fed with tubers and greenery of marsh plants. The significant part of diet of this species includes tree fruits have fallen on the ground, therefore monkeys of this species frequently watch groups of monkeys of other species, gathering fruits thrown by them.
Decorated squirrel guenon (Sciuropithecus ornatus). This representative of the genus differs in very bright colouring: bright-red body, white crest on head at animals of both sexes, long tail at the male is white, at the female black. The back side of palms and feet is colored coffee-brown. Face skin is naked and yellow. Males have small black “barb”. Cubs are colored uniform brown color; only face skin is yellow, as at adult monkeys.
Decorated squirrel guenon lives on the trees making forest canopy and practically does not go down to ground. This species even searches for water in leaves and crowns of epiphytic plants. Food specialization is available at these species: fruits of trees of family Sapindaceae including inedible for other monkeys contain more than half of diet of these monkeys. Fruits of some Sapindaceae are poisonous being unripe or overripe, but features of digestion of monkeys of this species permit to eat even them without harm for themselves. Due to it decorated squirrel guenon avoids food competition to other species of monkeys and also to rodents.
Blue-faced squirrel guenon (Sciuropithecus cyanofrons). Distinctive features of this species is naked bright-blue face skin at monkeys of both sexes and of any age, and also cross-striped black-and-white tails (as at ring-tailed lemur or the coati raccoon). The body is colored gray-brown color; wool on extremities is lighter, at males on chin and throat there are long hair form “beard”, and on head there is black “hat” contrasting with it. Cubs have uniform gray-brown colouring, and they do not have strips on tails.
This species spends a lot of time on the ground, therefore at them the feature similar with coati and ring-tailed lemur had developed: these monkeys keep striped tails vertically, therefore any member of group can notice easily neighbours among roots of trees. Life of these monkeys is closely connected to trees of fig (Ficus) genus, which fruits frequently ripen on trunks practically at the ground level. Other features of behaviour at these monkeys are common for representatives of this genus.

Caribbean crested guenon (Papiopithecus mitratus)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: Cuba, Great Antigua, sea coasts.

Picture by Alexey Tatarinov

Human activity rendered significant influence on fauna of various areas of the Earth. One of its consequences was occurrence of representatives of one or another group of animals and plants in places where they could not reach in natural way. Before people Old World monkeys had been absent in New World. Green monkeys (Chlorocebus sabaeus) had been introduced in human epoch to islands of Caribbean Sea from Africa; and they had quite got accustomed in new motherland and had successfully gone through miseries appeared because of ice age. When islands of Caribbean Sea connected to each other, forming the land bridge, descendants of these monkeys were settled at the largest islands, having formed some species well distinguished from each other, but had not undertaken attempts of colonization of continents.
One descendants of green monkeys lives in coastal forests of Cuba – it is Caribbean crested guenon, rather large and almost terrestrial monkey. Body length of adult individual of this species is up to 70 cm, weight is about 30 kg. In its shape this monkey resembles baboon – it has large head, front and hind legs of approximately equal length, rather small feet and hands, and the tail strongly shortened in comparison to forest species. Wool of these monkeys has yellowish-brown color, a little bit darker on back, but edged by strip of light, almost white wool – such colouring helps monkeys to distinguish each other. Tail about 25 cm long with white switch of long hair on the tip has completely lost functions of the balance weight – Caribbean crested monkey spends on the ground almost all day time, and only for night gets on trees for sleeping. Nevertheless, such tail has the important alarm value – its position and movements of monkey express its emotional condition. The important role in emotion expression is played by demonstration of canines which are especially advanced at males.
Caribbean crested guenons have clearly expressed sexual dimorphism. Males are larger, rather than females, have high dark cop looking like mitre on a top of head. At females the top of head is covered with short wool, and only in the middle of it the strip of dark wool stretches. Also at males hairless face skin has grey-blue color, and at females it is dark grey. Cubs of these monkeys have darker, almost black wool. Naked face skin which is colored light grey, almost white, sharply contrasts with its color. Juvenile colouring is a guarantee of the good reference to cubs: adults forgive monkey tricks and food theft to them. But, as colouring changes to one characteristic for adult individuals, the relation to cubs also changes and they are compelled to struggle for place in group hierarchy.
These monkeys move in forest in groups: male, 3-4 females and their cubs of several previous years. Male is the indisputable leader in group and it demonstrates the superiority, taking off the found food at females and juveniles. Young individuals, as a rule, leave parental group. The female almost always can join any other group, but males keep in barchelor groups at the forest edge, and from there they can encroach to harems of mature males in hope to take a place of the leader there.
These monkeys inhabit seacoasts and coastal forests. In the afternoon they wander on beaches, selecting the fishes thrown out by waves and crustaceans, and also collect from stones seaweed. They supplement the diet with fruits of trees or insects. At night these monkeys are arranged on branches of trees and sleep, closely having nestled to each other.
The courtship season is not expressed, and at any time in herd there are young individuals and females ready to breeding. Male confirms its rank with ritual poses more often and drives away contenders, showing to them grinned canines. Thus he rises on hinder legs and can make some steps while keeping such position .
Pregnancy at the female lasts till about 150 days, and more often two cubs are born. The lactation lasts up to about 8 months, but cubs start to try food of adult animals right at the third week of life. Puberty comes in 3-5 years. Life expectancy is till 25 years.
At Great Antigua Island subspecies of this monkey (P. m. antiguanus) lives – it is larger one having bright red wool and grey back. Monkeys from Great Antigua differ a little from inhabitants of Cuba in skill of gathering food in freshwater reservoirs. They can dive for food (monkeys from Cuba do not do it), but appear at sea coast less often.

The idea about existence of this species of mammals was proposed by Nick, the forum member.

Ngai (Ngai faber)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: rainforests of Zinj Land.
Although having lost some of their species during the epoch of human domination, cercopithecids, or Old World monkeys quite easily regained their biological diversity due to the rapid evolution of the survived species. Moreover, they partially managed to occupy the niches of great apes, which became extinct by the end of Holocene. In Asia, they formed a new family of parapongids, which includes kong, the largest monkey of Neocene. Ngai, having a convergent similarity to them (the name means the god of thunderstorm among the Masai), a descendant of the Syke’s monkey (Cercopithecus albogularis), evolved in Zinj Land in isolation. This species is one of the largest cercopithecids along with gorillada, agogwe and chemosit.
Ngai is characterized by a massive physique and does not climb trees well – only young individuals can do it. Large adult animals are capable of climbing sloping tree trunks and thick lianas, but they move very carefully and do not climb high. The height of an adult in a bipedal position is about 1.6 m, and weight is 60-70 kg; male is larger than female. Forelimbs and hind limbs are approximately the same length. The strong development of the thumb on the hand is noteworthy. Foot with the abducted thumb retains grasping functions, but is elastic and springy due to ligaments. Tail is reduced.
Wool is reddish-brown with a silvery tinge on the shoulders and upper back. In older individuals, especially males, wool coloration turns lighter. Face, feet, and palms are hairless. Skin on the face of females and cubs is pink, in males it is red and darkens when the animal is agitated. In adult males, there is a zone of tissue rich in blood vessels under the skin on the cheeks and temples. In a state of aggression, blood rushes to it, causing the appearance of swollen face flanges that visually expand the face. At rest, the face is wrinkled, resembling an old man’s face. Hair on the head is dark brown, and a beard of white hair grows from the temples to the throat and chin along the edges of the face, being especially well developed in males; females have only a small patch of elongated white hair on the throat and chin. The male also differs from the female in his large canines. Molars are large and have thick enamel layer.
Ngai feeds mainly on vegetative food – mushrooms, fruits and leaves; invertebrates and small vertebrates supplement the diet. This animal has a very long intestine, so the belly looks swollen. Animals are quite slow-moving, spending a lot of time chewing food.
Brain volume reaches 350 cubic centimeters. Ngai has a relatively complex behavior: rudimentary cultural skills accumulate in various groups, such as the ability to use objects to get food. Many animals can crack nuts with stones, and experienced adults teach this to their cubs. Some animals can make flakes by hitting two stones together and cutting off a piece of hard leaf with a sharp flake. But these monkeys do not carry such tools for long; they are more often abandoned immediately after use. When trying to get particularly attractive food, the primate easily stands on its hind legs and can stand like this for up to 2 minutes, for example, picking off fruits or leaves. The guards of the group often behave so. Ngai is a social animal. In a breeding group, there are 15 to 40 animals, including a dominant male, 1 or 2 subdominants, several females and their cubs. The male is larger and more aggressive than the female. Therefore, the meeting of two unfamiliar adult males, or the expulsion of adolescents turns into a violent displaying and is accompanied by screams and fists knocking on the plank-buttress tree roots, causing a sound like a drumbeat to resound through the forest. Adolescent males live separately from adults until they acquire their own territory and harem. While there are no females in such a male group, they treat each other relatively peacefully, but when a female appears in the group, skirmishes break out and active rivalry ensues, ending only after the female leaves with her chosen male. Often, young males seize power in an established group, expelling an aging male. After wandering through the forest, such males also join groups of young males and become a kind of “teachers”, transferring to young animals their skills acquired in their youth while living in a group. Such a group is able to give a coordinated rebuff even to a large predator like noonda: during the fight, monkeys throw stones at it and poke it with long branches, forcing it to retreat. In bachelor groups, outcast males have a chance to live to old age.
The mating season is not expressed. However, in a group, mating behavior synchronizes quite quickly, and the number of females ready to mate exceeds the number of males. Pregnancy lasts about 7 months, and for another three years the cub is largely dependent on the mother. By the end of this period, the female can already give birth to the next cub, and gradually her care goes only to it, forcing the previous cub to form its own social ties in the group. All females, starting from the age of 6 years, help the mother to take care of the cub. At the same age males are driven out by the dominant and form bachelor groups. Puberty begins at the age of 11, and ngai’s life expectancy reaches 65 years. In groups, females often survive to a post-reproductive age, becoming babysitters for all the cubs of the group at once. The life span of males is usually shorter.

Guardian guenon, saber-toothed guenon (Smilopithecus macrodon)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: savannas of North Africa.
The Old World monkeys, and guenons in particular, turned out to be one of the most successful Old World primates. Of course, they lost some of their species during the epoch of anthropogenic pressure. But after the extinction of humans and great apes, they began to occupy the vacated ecological niches actively, and their diversity increased drastically. Large Asian parapongids and African gorilladas evolved among them, being peculiar analogues of Holocene anthropoid apes. Many of the guenons of the Old World live in forests, but some species inhabit savannahs. One of the common species of the savannah is guardian guenon, a descendant of the common patas monkey (Erythrocebus patas).
This monkey species is large, but has a lean build. Body length is 80 cm, tail is 55 cm, weight is 15-20 kg; male is larger than female. All limbs are long, and feet and hands are relatively small. Wool on the upper side of the body is usually rusty-brown, less often black, red or gray; chest and belly are of lighter dirty white color. Face and ears are hairless, covered with pinkish skin, which turns very red when the animal is excited. Skin on the back of the hands and feet is covered with sparse hair.
This species has a pronounced sexual dimorphism, which is manifested not only in size, but also in appearance. Males have larger jaws, and the canines in the upper jaw are very large, protruding from the mouth (hence the second name of the species). Such canines serve to establish dominance relationships, as well as to intimidate enemies. Canines are strong enough to cause deep puncture wounds when bitten.
Saber-toothed guenons live in groups of 14-18 adult animals and their young; in each such group there is a dominant with the exclusive right to mate with females, and 2-3 subordinate males who manage to mate only stealthily. The hierarchy is strict, with the dominant male constantly maintaining his status with threatening noises and displays of canines and exposed gums. When an enemy attacks, the dominant male behaves aggressively, baring his canines, attacking by biting, and immediately running back. Fangs inflict deep lacerations on predators.
Despite the armament of the males, these monkeys feed mainly on grasses, grains of cereals and legume seeds, as well as insects. If possible, these monkeys eat fruits and berries. Guardian guenons can often be found near herbivorous animals, where they catch insects startled by their neighbors. Harelopes even benefit from the proximity of these monkeys – a clan of saber-toothed guenons will easily drive away a monitor lizard, a barbed herzogcat, a small dog or a viverrid, screaming and bombarding the predator with hassocks, stones and pieces of earth. Occasionally, these predators sometimes prey guenons, attacking them from an ambush.
The breeding of saber-tooth guenons takes place all year round. In females, during the ovulation phase, the genitals swell and the skin in the genital area turns red. At this time, conflicts for the right to mate escalate in the group, and fights for privileges easily break out between males. The males scream, stand on their hind legs and show their canines to each other. The individuals with the largest canines are most attractive to females, although this often prevents them from chewing their food properly. After a pregnancy lasting about 180 days, the female usually gives birth to one cub weighing about 0.7 kg, with black hair. At the age of one year, it weans from milk and completely switches to the diet of adults. Puberty comes at the age of 7 years. Males usually leave the parent group, while females often remain in it for life. Life expectancy is 30 years.

Golden feather-tailed Monkey (Ptilocebus aurata)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: African jungles east of the Congo River, to the shores of the Tanganyika Strait.
Of all cercopithecoid monkeys, mangabeys suffered the heaviest losses. Of the two genera of these monkeys, only one species persisted in each of them; others have become victims of hunting and deforestation. However, the surviving species not only survived, but also evolved in the rainforests of the Early Neocene, giving rise to new species, including those with bizarre specializations. One of them is the golden feather-tailed monkey, a descendant of the agile mangabey (Cercocebus agilis), a true gem of the rainforest.
It is a small primate having a very remarkable appearance; the body length is 56 cm, the tail is about 65 cm long and not prehensile. The wool color is golden with variations from straw yellow to rusty, sometimes ochre-red. Sideburns of long white hair fringe the blue-skinned face, and males have a small black beard. The sciatic calluses are blue. Sexual dimorphism in size is almost not pronounced: the male is only about 10% heavier than the female. At the tip of the tail, individuals of both sexes have two comb-like rows of long, rigid white hair, making it look like a feather. This tail acts as a balancer when monkeys jump on branches or between trees, as well as to give visual signals. Thumbs on hands and feet are well-developed and opposable. Thanks to its tenacious limbs, the monkey can climb even on thin and flexible branches.
Golden feather-tailed monkeys search for food both in trees and on the ground. They feed on fruits, including those with very dense peel, nuts, leaves and mushrooms, supplementing their diet with insects and snails, eggs and chicks of small birds.
These primates live in groups of 15-20 animals – 2-3 pairs of adults and their young. They communicate both with the help of sounds and movements of the tail: if it is raised, then everything is calm, sharp swings accompanied by squeals express an aggression, and a hidden tail and hooting are an alarm signal. Groups of these monkeys protect trees with their favorite food from their relatives, the rest of the time they are tolerant of each other, and the territories of different groups overlap significantly. During feeding in the common area, monkeys can move from one clan to another.
The breeding season is not pronounced. Being ready to mate, the female often walks around the males, squealing and shaking her tail, and displaying her butt with swollen genitals and sciatic calluses. She usually mates with a male, with whom she forms a permanent pair, but sometimes the female does not interfere with the courtship of another male, especially when her partner does not see her. Young “bachelor” males, trying to attract the attention of a female, can scream and shake branches, and adult “family” individuals more often groom each other, rather formally displaying their willingness to mate. After 175 days of pregnancy, the female gives birth to a single cub. It is fed with milk for 2 months, and later it passes to adult food. At about 9-10 months of age, the young monkey already spends more time in the company of peers, and at 14 months reaches full independence. At 20 months of age, young animals can leave the family, forming bachelor groups, or move to neighboring clans. They are sexually mature by the age of 3 years, although males take part in reproduction more often since the age of 4.5 years. Life expectancy is up to 36 years, with females reaching a post-reproductive age (about 30 years) and becoming common “babysitters” for the cubs of the clan.
Congo feather-tailed monkey (Ptilocebus congensis), brown in color, with a body length of 75 cm and a tail of 80 cm, lives in the Congo Valley. It also has a feather-shaped tail with white hair, but the skin on its face is darker, purple-black, and its golden-yellow eyes look especially impressive against this background. White fur borders the sides of the face and forms a beard in both males and females. The biology of these species is similar, but the given species spends significantly less time on the ground and often climbs emergent trees. The alarm signal sounds like a dog barking.

Swagbelly (Pseudopan sylvestris)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: Equatorial Africa, tropical rainforests.
Among the cercopithecid monkeys of Equatorial Africa, only a few species have survived, managed to endure deforestation and hunting. One of the successful survivalists was the agile mangabey (Cercocebus agilis), which has a flexible behavior and a varied diet, which gained a survival advantage from this. This allowed it to survive the Ice Age and give rise to new forms. Among the descendants of the agile mangabey, there is a swagbelly, semi-terrestrial, slow-moving primate that feeds on the green parts of plants.
The body length of an adult is up to 100 cm, excluding the tail, and the weight is about 36-40 kg; males are larger than females. Wool on the body is black; elongated white sideburns grow on the head, and the males also have whiskers of the same color. Their size depends on the hormonal balance of the males, and they are especially large in the dominant male. Sexual dimorphism is also sharply expressed in the size and presence of skin formations on the head: males are larger, with skin outgrowths extending from the temples to the chin on their muzzles, used for threatening displays. Inside these outgrowths, the tissues are rich in blood vessels, and when the animal is agitated or aggressive, they fill with blood strongly, which makes the male’s muzzle seem almost twice as wide as the female’s one. The skin on the face and growths are yellow.
Externally, the swagbelly resembles a shaggy and heavy-built tailed chimpanzee. Unlike most monkeys of the Old World, the swagbelly has a prehensile tail. Due to the slowness of the animal, it is not suitable to perform the function of balancer, but it allows the animal to fix itself on branches during feeding. The underside of the tail is covered with heavily keratinized hairless skin.
Head has large jaws, only slightly protruding forward – the animal’s muzzle resembles the faces of hominids. The chewing muscles are well developed and strong – swagbellies can crack hard nuts with their teeth, and ripen legume seeds are easily chewed dry. To attach the chewing muscles, at the animal a pronounced sagittal crest is developed, further increasing the height of the head. Because of this, the animal’s crown has a conical shape. The canines are shortened, which allows these animals to chew effectively with the help of lateral movements of the jaws. The molars are large and have a thick layer of enamel.
The brain size is relatively small – it stops growing very soon: the cranial sutures close during ontogenesis in the third year of life. Compared to other primates, these monkeys have a rather primitive behavior: there is no tool activity and specific cultural skills in various groups of them. However, their memory allows them to remember a large number of edible and poisonous plants in childhood and throughout their lives.
The swagbelly is heavy, but quite mobile for its size. When attacked by a predator, animals are able to quickly climb a tree. If they have to fight a predator, they grasp it with their hands and inflict bites. Despite the short canines, the bite of these animals is very strong.
A notable feature of the appearance of these primates is the large belly, accommodating a long intestine. The stomach is also bulky and two-chambered – the anterior section works like a rumen in ruminants, and fermentation of chewed vegetable matter takes place in it; the second chamber is the glandular stomach, where food is exposed to digestive juice. The animal also has a voluminous cecum, in which bacterial colonies settle, supplying the animal with vitamins. Swagbelly feeds mainly on leaves and mushrooms, occasionally picking up fallen fruits. Its favorite plants are the giant herbs of parsley family, including those poisonous to other herbivores, as well as the leaves of ficuses and plants of milkweed family. Swagbelly is one of the few herbivores that can digest these pungent, poisonous, and latex-rich leaves, and such dietary features allow this primate to avoid competition with other herbivores. Regularly, clans of these animals can be seen at the outcrops of certain clays and minerals that help remove plant poisons from the body. These are the only meeting places where various groups of swagbellies do not treat each other aggressively. The mineral “canteens” of the swagbellies represent a kind of “clubs” where meetings of single animals take place. It is here that a young animal can move to another clan, or young singles find bachelor groups and join them. Outside of the clay outcrops, the swagbellies are intolerant of each other and expel rivals from their territories with the help of screams, threatening displays and physical force.
This monkey species clan consists of 3-4 males, among which one is the dominant one, 6-8 females and their offspring. The breeding season is not pronounced. The female, ready to mate, walks around the males, making soft noises and showing her genital area, which is strongly swollen at this time. The dominant male has the advantage in mating, although females show selectivity and personal sympathies towards males. Pregnancy lasts eight and a half months, one cub is born, and twins are very rare. The young ones stop feeding on milk at the age of one year, and at the age of 4 they are already completely independent. Puberty begins at the age of 6-8 years – earlier in females, later in males. By this time, males usually conquer their territory and clan, or, like females, join their neighbors. Life expectancy is about 40 years.

Obambo (Brachiocebus obambo)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: African jungle, forest canopy.
Guenons are perhaps one of the most successful groups of Neocene primates. Diverse and numerous, they survived the human era with relatively few losses. One of these losses happened among the mangabey monkeys: by the end of the human era, only one species had survived in each of two genera of these monkeys. But in due course of ecosystem restoration, these species have given rise to a wide range of descendants in the tropical forests of Africa. Among them, there is the obambo, a descendant of the grey-cheeked mangabey (Lophocebus albigena).
With a relatively large size, this monkey species has a lean build: body length is about 75 cm, weight is up to 8 kg. The arms are very long, their span reaches 1.12 m. The length of the tail is up to 80 cm; unlike other monkeys of the Old World, this species has a prehensile tail, which allows the monkey to move along the branches, hanging from them from below.
The wool color is gray (hence the name: ghost in the mythology of the folks of Central Africa). A tall crest of brown or black hair grows on the head (especially in males), and the face is red. Males have very well-developed canines, they are slightly larger than females. Obambo lives in trees, moving along branches with the help of brachiation. When moving, the monkey secures itself with its tail, choosing the safest path or trying to reach a more delicious piece. Obambo never descends to the ground and drinks rainwater from hollows or rosettes of epiphytes.
This species has evolved convergent similarities with gibbons and hominids, having the ability to walk on its hind legs, keeping its body straight. The foot has a peculiar anatomy – it is elongated and has a very strong and mobile thumb. The four other toes of the foot are connected by skin up to the nails, and the foot functions as a claw, allowing the monkey to walk along thin branches, firmly grasping them with feet and maintaining balance by grabbing neighboring branches with its hands and tail.
Obambo feeds on soft, high-calorie food like fruits and young leaves, occasionally getting eggs and chicks, small reptiles, frogs and insects. These monkeys live in groups of 8-12 individuals – mostly a breeding pair and their offspring, or a group of cognate females and 2-3 males. The territories of the groups may overlap, and obambos protect only trees with the most delicious leaves or fruits – different groups have their own ones. Every morning, the animals call to each other, uttering loud screams and listening to the neighbors.
The breeding season is not pronounced: at any time of the year, females with cubs or a mating pair can be found in groups. These primates are monogamous, but males often seek to mate with other females of their group. In an established pair, partners groom each other for a long time, making gentle sounds, or feed each other. Bachelor or widowed males try to kidnap females from their neighbors by performing noisy displays including screaming, jumping on branches and shaking them.
Pregnancy lasts 222 days, after which 1 cub is born; twins are rare. The cub has a black coat and a pink face. Juvenile coloring is a kind of “security certificate” for the cub, encouraging adults to forgive its tricks and treat it condescendingly. The cub learns for a long time to climb trees with the same dexterity as adults and to search for food. The obambo female feeds it milk for up to 6 months, after which it switches to completely adult food, and the female is ready to mate again. A young animal spends up to 1.5 years with its mother, leaving her shortly after the birth of a new cub. The young males left without maternal care live in their clan for some time as the lowest members in the hierarchy, and eventually either leave it on their own or are expelled forcibly. Such males gather in bachelor groups and roam the border territories of various clans, trying not to approach the owners of the territory. Females can live in the parent group for the rest of their lives, although sometimes they move from one clan to another or join groups of males. Puberty begins at the age of 4 years; males try to win over females since the age of 5. Life expectancy is up to 40-45 years.
The main natural enemies of these primates are birds of prey. Some of the young die falling from the trees while learning to climb.

Chemosit (Gravipapio chemosit)
Order: Primates (Primates)
Family: Old World Monkeys (Cercopithecidae)

Habitat: South African savannas.

Picture by Alexey Tatarinov

Among the Old World monkeys, the baboon genus contained the most heavy primates after great apes, including mandrills and drills, whose number decreased greatly, however, in the era of Holocene human pressure. The changes in nature at the conjunction of two eras had destroyed the chances of survival for those species, as well as for great apes proper.
But besides mandrill and drill, among baboons there were many other relatively large primates, more suited to survival in the face of changes in their habitats. One of them was the Chacma baboon (Papio ursinus). An inhabitant of savanna, not the jungle, omnivorous, inclined to carnivory, it succeeded greatly and after the disappearance of people it evolved to chemosit, one of the largest primates of Africa.
Chemosit is actually a baboon of very robust constitution. The length of chemosit male may reach 3 meters, of female – 2-2.5 m; the short tail is 10-15 centimeters long. Its body is covered with yellow-brown hair, except for muzzle and butt, which are covered with black hairless skin; also mature males grow sideburns and beard of brighter, whitish color.
Hands and feet of chemosit have kept the general similarity with those of other primates, but its fingers are very rigid, almost non-bendable, with the exception of thumbs, therefore their grabbing ability is very limited. Hind legs are somewhat more powerful and longer than forelimbs, so chemosit can stand-up on them for a while for a better view of its surroundings or to frighten its enemy or rival congener. When moving, the rump of animal is slightly above the shoulders.
The main weapon of chemosit is its teeth. Both they and the jawbones are very thick and powerful. Canines can cause deep lacerations and break a neck of even a big animal, but chemosit hunts rarely. It prefers to eat carrion, or to steal prey from other predators. It also eats vegetative food, like hard pods of acacias and other plants. When searching for insects it breaks into anthills, termite mounds, and wasp and bee nests; due to its thick skin this animal easily endures their stings. The smaller females of this species especially love wild African cereals and similar plants.
Among chemosit males loners are frequent; sometimes they live in groups of two to three individuals. Successful males lead harems of 4-5 adult females, while protecting their offspring. Each female typically gives birth to one cub once in three years; twins are very rare.
The mating season of chemosit is not distinctive. Single males constantly impinge on the harems of alpha males and roam on the borders of their territories, declaring their intentions in loud roars. Periodically there are attempts of alpha males to win over females from their neighbors; usually it is a displaying of force and the length of canines, but on occasion real fights happen.
Young monkeys remain in their family’s clan until the age of three, and then they are banished. Puberty in females occurs at the fifth year of life, in males at the sixth or seventh year. The life expectancy of the chemosit can reach 35-40 years.

Grey-haired baboon (Feropapio canus)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)

Habitat: Southwest Asia, mountains and semi-deserts.

Picture by Lambert

The Neocene was another period of change in the evolution of higher primates. Humans, which exterminated other primates and destroyed their habitats, have disappeared. The area of forests all over the planet was greatly reduced at first, and then returned to its former borders. The great apes died out, and the lower Old World monkeys of the Cercopithecidae family settled to new habitats. Some species have even adapted to life in habitats that are uncomfortable for primates.
The grey-haired baboon is a relative of the furiobaboon (Feropapio furiosus), a successful predator of the North African savannahs, but differs from it quite significantly, primarily in its size and ecology. This species does not exceed 74-84 cm in length, plus another 15-20 cm is the tail, males weigh almost twice as much as females. Its back, shoulders, and head and neck are covered with dark hair, which partially lightens with age and becomes more yellowish or whitish in adult animals (hence the species name).
The wool on the muzzle is very short; the skin is of light pinkish-gray color. The muzzle of the gray-haired baboon is somewhat reminiscent of the muzzle of Holocene camels, specifically, because of the valves in the nose that help this primate to exist in the arid climate of Neocene Southwest Asia. Jaws are strong, adapted for crushing tough vegetative food and insects. Canines are large and serve to protect against enemies and establish dominance relationships. The brow ridges are large, and the head is protected from overheating by thick fur. A prominent crest grows on the crown of both males and females, which serves to attach strong masticatory muscles. This monkey species has relatively large ears, which serve to remove excess heat from the body.
From behind, especially on the feet and under the tail, skin calluses develop at this baboon, due to which it can sit even on hot rocks or on sand without experiencing any particular inconvenience. There are also small calluses on the palms, but it happens that in especially intense heat they do not protect from the heat of hot stones in the sun, and monkeys have to stand for a long time, and even walk on two legs. In addition, this monkey species has developed the ability to accumulate fat reserves in the tail and buttocks. Because of this, the animal’s butt gets even bigger. The skin around the sciatic calluses is brightly colored – in males it is bright red, and in females it is pink. The large size of the butt is a sign of the animal’s success in finding food, as it clearly demonstrates the accumulated fat stock.
The gray-haired baboon is a primate of twilight activity. Its daily activity has two peaks: from early morning to noon and in the evening. Day and night, it prefers to hide in small groves, in caves and near water, if possible. Due to the small amount of food in the habitats of this species, gray-haired baboon lives in small groups: 1-2 males, 3-6 females and their cubs. If there are a larger number of males in the group, the dominant male shows aggression towards them. While resting, adult animals take turns watching, but birds of prey sometimes manage to get a heedless monkey.
The diet of this species includes small invertebrates, lizards, rodents, occasionally non-venomous snakes, bird eggs and chicks. Plants and fungi make up a significant part of the diet, and if possible, these monkeys willingly eat carrion and the remains of prey from predators. The tool activity of this species is almost undeveloped: they can only throw stones and sticks at the predator.
The mating season and the birth of offspring are extended throughout the year, but cubs are more often born in the first half of spring, when it rains and there is enough food. Usually only one cub is born, twins are extremely rare; the cub has very light gray wool. Mothers carry them clinging to their stomachs to shield them from the sun at least partially; the cubs have a very tenacious grip, and they easily hold on to their mothers when they run. However, most of the young monkeys of this species die precisely because of the severity of the climate, and not from attacks by predators (birds, monitor lizards and snakes), or from diseases. The cubs are the concern of all the females of the group, and even the dominant male is condescending to the cubs’ attempts to steal food from him, and often participates in grooming the cubs.
The average lifespan of a gray-haired baboon is about 18-20 years, but many monkeys die earlier. Dominant males who are the first to encounter danger are especially often killed.

Etugen, steppe obda, small obda (Obda etugen)
Order: Hoofed lagomorphs (Ungulagomorpha)
Family: Titanolagids (Titanolagidae)

Habitat: steppes and semi-deserts of Central Asia, west to the shores of the Fourseas.

Picture by Cossus

In Neocene, Eurasia became the birthplace of two groups of herbivorous animals, which include large herbivorous species – trunk boars (Proboscisuidae) and titanolagids (Titanolagidae). Unrelated to each other, these animals have a significant impact on landscapes. One of the largest species, the thick-foreheaded obda (Obda pachyfrons), migrates in large herds across the taiga zone, disrupting the crown-contact of the forest canopy and contributing to the appearance of a mosaic landscape with high species diversity. In the steppes of Central Asia (up to the eastern shore of the Fourseas), its close relative, the smaller etugen, or steppe, or small obda, lives. This representative of hoofed lagomorphs has adapted to life in open spaces and is an ecological analogue of the African flathorn (Platyceratherium foetidus) in the Central Asian steppes. Due to the activity of this animal species, forests and shrubby thickets cannot completely occupy the steppes, leaving room for perennial grassy vegetation. Hence the name of the species “etugen” after the Mongolian goddess of the earth.
Etugen is a little bit smaller version of its taiga relative. The body length of an adult animal is about 3 meters with a withers height of 1.5 meters. The frontal bones of the animal are thickened, but weaker than in a related species; the muzzle is short and expanded, with strong jaws. The summer wool of steppe obda is reddish-brown with variations from straw-yellow to chestnut-colored with black markings, and the winter wool is long and white. Etugen lives in herds of 15-25 animals, consisting mainly of young animals. At the head of the herd, there is a male with a harem of 3-4 females, and the other animals represent their offspring. Sometimes herds of bachelor males are formed.
This animal is constantly in search of food and roams in open places. The herd moves slowly across the steppe, eating coarse grasses and browsing branches of trees and shrubs. In the case of winter starvation, steppe obda digs up the snow with its muzzle and eats the young shoots off to the ground level. Harelopes, saigochenias and other herbivores feed on the dig sites of steppe obda. Due to constant browsing and trampling, shrubs and trees grow quite poorly in the habitats of steppe obda. Thickets of shrubs grow only where obda avoids to appear, or where it haven’t appeared for a long time. They usually thrive along riverbanks and on steep slopes where movement of these large animals is difficult.
The rut in steppe obdas takes place in the middle of summer and proceeds relatively calmly; skirmishes usually occur only with young bachelor males, but most often the animals confine to displays – roaring, shaking their heads and digging the ground. A large male, defending his right to females, urinates profusely on the ground and on bushes – during the rut, his urine has a pungent odor. Pregnancy lasts up to 10 months; in the spring, the female gives birth to one, less often two cubs. The cub is born well-developed, begins walking and follows the mother very soon. It does not lag behind its mother even at the age of one day – like its large relatives, steppe obda does not run well and runs rarely. Until winter, it feeds on fatty milk and quickly gains weight, but gradually accustoms to eat vegetative foods. By the age of one year, the cubs pass to adult food, and at the age of 3-3.5 they leave the herd. Males leave the herd earlier – the adult male begins to express aggression towards them. Females usually “get lost” in winter, forming groups of animals of the same age. Steppe obda reaches puberty at 4.5 years old, but if the female quickly enters someone’s harems, then young males do not take part in tournaments for the female until about 7 years of age: a full-grown male will easily drive the young applicant away from the herd. Occasionally, young males manage to mate with a female, while one of their peers distracts the attention of an adult male, and 1-2 cubs in the herd, as a rule, are not the offspring of the owner of the harem.
The life expectancy of steppe obda reaches 35-40 years.

Umingmak (Arctotitanolagus umingmak)
Order: Hoofed lagomorphs (Ungulagomorpha)
Family: Titanolagids (Titanolagidae)

Habitat: Central and Northern Eurasia, Beringia and Alaska (it is the only species of hoofed lagomorphs penetrated to New World).

Picture by Tim Morris

In Holocene fauna of Eurasia herbivorous mammal were presented by hoofed mammals of various families – mainly by deer and bovines, and also by less numerous pigs, elephants and perissodactyls (horses and rhinoceroses). As a result of human activity, hunting and habitat destruction, the majority of families of hoofed herbivores had disappeared. In Neocene bovines and deer had kept mainly in southern part of Eurasia and Africa where after human disappearance they had formed some separate families. To the north of ranges of Central Asia, in Europe, Siberia and Far East, the fauna of herbivores is presented by various descendants of pigs, and also by new group of animals – hoofed lagomorphs. This order of mammals, descended from true lagomorphs, includes animals of two types – gracefully built harelopes living in savannas, woods, steppes and mountains, and massive herbivorous huge lagoids to which aurochid from Northern Eurasia and huge obda from Siberia belong. These animals inhabit woods of Eurasia, and mountains of Eastern Siberia, Beringia, Alaska and plains of Far North are inhabited by one more species of massive line of hoofed lagomorphs, the umingmak.
“Umingmak” is the Eskimo name of musk ox. It indicates a role of this animal in ecosystems of northern latitudes: it is an ecological analogue of artiodactyls of Holocene epoch. Umingmak is the herbivorous cow-sized mammal. It lives the year round in conditions of seasonal sharply continental climate, not making long migrations like obda. In winter in habitats of this animal there is the thick snow layer and the temperature sinks up to -30°С, but umingmak is adapted to survive and to exist normally even in such inclement conditions.
In severe conditions of the North it is better to struggle for survival in common. Umingmak is gregarious animal keeping in herds of 30 – 40 ones and sometimes even more. This animal prefers district where wood and plains are combined. In winter umingmak avoids places where the thick layer of snow falls – in searches of forage it should dig snow out; therefore these animals go to forests. Umingmak frequently comes to frozen wood bogs where it is easier to find high last year's grass.
The animal is well adapted to severe climate of Siberia. Foot of umingmak is wide: it permits the animal to not fail in snow and to wander freely in snow-covered woods. Umingmak runs badly – its maximal speed is about 45 kms per hour. But the predator all the same can not catch it up on friable snow. Back legs of the umingmak are little bit longer than front ones, and the back is inclined forward – this animal meets in mountain areas of Central Eurasia and Beringia, and grazes on slopes. In winter umingmaks often meet in mountains, especially in areas where the wind blows snow off. They graze stalks of last year's grass and young branches of bushes. On nose of this animal the cross horn comb is advanced, assisting to dig snow. It gives to the animal some similarity to rhinoceros.
At the ground dug by umingmaks other herbivores, snow harelopes, distant relatives of the umingmak, feed. Umingmaks frequently search for forage in common with another large herbivore – Siberian shurga, the huge boar descendant. But they keep aloof of this aggressive animal, and feed with the rests of grass and bushes when shurga goes out.
Similarly to their far ancestors, hares, umingmak changes color of wool according the season. Summer wool of this animal is short and brown, lighter on cheeks and stomach. On throat and neck of males the “beard” of long hair develops – it is the secondary sexual attribute characteristic for various species of huge lagoids. Except for it, males of umingmaks differ in massiver head, rather than females. In summer wool on back of animal dark “belt” stretches. Winter wool of umingmak is long and white with grayish shade. At this time at the animal rich thin underfur develops. In spring shedding umingmaks find coniferous trees with dried up bottom branches, and scratch against them, leaving on branches and trunk flocks of shedding winter wool. At this time small birds take wool of umingmaks to build nests. And larger birds even sit on backs of grazed umingmaks and pull wool out right at animals. It does not cause them any anxiety: wool of this animal in general keeps in skin unsteadily, and easily drops out, if it is pulled out strongly. This feature rescues young umingmaks from small predators.
Head of umingmak is massive, with thick frontal bones and short strong jaws. The nasal cavity has grown up, nostrils are able to close – with their help animal adjusts temperature of inhaled air. Ears of animal are short and rounded – such feature had developed in cold climate where it is unprofitable to warm-blooded animal to have strongly extending parts of a body increasing heat emission.
Molars of umingmak are plicated and constantly growing – it is connected to diet of animal which includes rigid grass and branches of bushes. Forward pair of top incisors is wide, and all incisors of animal grow constantly. The feeding animal can bite across small branches of bushes. Umingmak is the exclusive vegetarian. In summer it eats leaves and grass, occasionally browses branches of bushes. In winter when it is very difficult to search for food, umingmak becomes less legible in forage: by wide feet and muzzle it digs out snow in searches of last year's grass and evergreen bushes. If the layer of snow is too thick, umingmak can rear and eat branches of trees, basing forward legs on tree trunk. It can eat even conifer needles.
The simple stomach of umingmak had actually turned to the fermenting chamber in which symbiotic bacteria live. Umingmak does not chew cud like artiodactyls, and digestion occurs, basically, in long bowels. For digestion of rough vegetative forage at the umingmak the volumetric caecum also occupied by bacteria is developed. Fermented food gets first to caecum, and then to bowels.
The rut of umingmaks takes place at the end of summer when animals are in the best physical condition. The female ready to pairing emits the special smell involving males. Around of such female some males gather and persistently follow behind her. Males establish hierarchy among themselves: they fight, pushing the contender away from the female by sides and shoulders. Occasionally, when there are two males of about equal force, they can even bite each other. The female emitting the specific smell can be attractive to males till some days, but it is ready to fertilisation till some hours per year. At this time one of strongest males from her “retinue” simply drives contenders off and protects the female, frequently pairing with it.
Pregnancy at umingmaks lasts about 10 months, and in spring at the female one cub (twins are extremely rare, and usually one of twins does not survive) is born. It is well advanced, and right after birth rises on legs. Umingmaks walk slowly, and run only in extreme cases, therefore the cub does not lag behind herd already at the first day of life. It is fed with fat milk and quickly gathers weight: at the autumn young umingmak weighs already about 300 kgs. The significant part of cubs had not reached age of two years perishes of winter fodder shortage. Having survived in first two years, young umingmak has an every prospect to reach maturity. Males mature at the age of four years, and the female do it at three years.

Wetland aurochid, or hazze-buffel (Lepotaurus palustris)
Order: Hoofed lagomorphs (Ungulagomorpha)
Family: Titanolagids (Titanolagidae)

Habitat: swamps and wetlands of Northern Europe.

Picture by Wovoka

A species related to the forest-dwelling aurochid, which is an analogue of the water-buffalo. One of its names, hazze-buffel, means “the hare buffalo” in the Frisian language. This is a rather rare animal, and the main habitat of this species is the marshes and wetlands of Northern Europe from Britain to Sweden along the shores of the North Sea. If the forest aurochid periodically comes into the wetlands, then the wetland aurochid lives there all the time, both in summer and in winter.
Wetland aurochid is smaller than its forest relative, weighs up to 450 kg and feeds on wetland plants: cane, reeds, sedges, horsetail, etc. In salty swamp areas, it willingly eats halophilous grasses such as glasswort and marsh grass. It is an animal of massive build with a large head on a short neck. Its ears are shorter than those of the forest aurochid, movable, located on the sides of its head and can turn in different directions. In winter, the outer side of the ears is covered with thick hair. Just like its relative, hazze-buffel has a patch of very dense thick skin on its nose, which helps to dig up the forest floor.
Skin is covered with shaggy hair; by winter, the wool becomes thicker due to the growth of the undercoat. Unlike its relative, the body coloration in summer is ochre-red with several vertical black stripes on the rump (in cubs, such stripes cover the whole body, like in zebra); in winter the wool lightens significantly. A black longitudinal stripe is stretched along the back from the shoulders to the root of the tail.
Toes have turned to a semblance of camel’s feet: they are interconnected by skin, and a soft paddle of elastic tissues is formed under the digits. Such feet can endure the weight of a heavy body on swampy soil, and also help to walk on mudflats during low tide.
Tail of hazze-buffel is longer than that of the forest aurochid, and is also covered with very long hair, resembling a horse’s tail. Such tail helps to chase away mosquitoes and midges, which are abundant in the habitats of this species.
The food of wetland aurochid includes not only grasses, but also leaves and bark of young shoots (especially willow trees), in summer and autumn mushrooms and berries are added to it. In preparation for wintering, the aurochid actively puts on weight and gets fat by winter; at this time, a small hump appears on the shoulders of the animal. In winter, the animal stays near the sea coast, where it eats seaweed and halophilic plants cast ashore by storms, as well as in the marine marsh areas, where it is possible to find tall last year’s grass. At uplands, the beast mainly eats shrubs and branches of low-growing trees.
Unlike its forest relative, wetland aurochid lives in groups of 3-9 animals (a male, two or three females and cubs). The mating season takes place in early autumn. At this time, the males are fighting with each other. Unlike the forest aurochid, they butt heads, and the bones of hazze-buffel male’s skull are thickened and form a noticeable bulge.
In early summer, the female gives birth to 1-2 cubs. The cubs are developed, have opened eyes, stand on their feet within 1 hour after birth, are able to follow their mother after 3-4 hours, and after 5 hours they are already able to swim. The whole herd protects the cubs from predators, and in the case of the death of the mother, the cub can easily feed on the milk of other females. It happens that an orphaned cub is adopted by another female, who begins to produce milk. Due to this feature, the survival rate of cubs is very high. Young females leave their mother at the age of 4 years, joining some new herd under the male’s leadership. The growing males leave their mothers at the age of 3 years, and then these youngsters create bachelor groups roaming the territories of breeding groups for another two or three years. Young females reach sexual maturity at the age of 4 years, and males at the age of 5 years, but active growth still continues, and slows down by about the 7th year of life. Life expectancy can reach 25-30 years.
The voice of adult animal is a snort that sounds like in forest aurochid, and when aggressive, it utters a hoarse low roar. The cubs, when startled, make a sound resembling sheep bleating.
There are known cases of interbreeding of forest and wetland aurochids on the borders of their ranges. Just as in the case of interbreeding between marsh and snow harelopes, male hybrids are sterile, but female hybrids are most often fertile. The coloration of hybrids is usually light brown with a golden sheen, and sometimes with black stripes on the rump.

Siberian marsh harelope (Heterolopa palustris)
Order: Hoofed lagomorphs (Ungulagomorpha)
Family: Harelopes (Lagolopidae)

Habitat: Siberia, riverbanks, lake coasts and vast wetlands.

Picture by Cossus

A species of hoofed lagomorphs closely related to the snow harelope (Heterolopa niveophila), a representative of a characteristic Eurasian-African group of herbivores that evolved after the end of the human epoch.
The affinity of the two Siberian harelope species is particularly noticeable in their winter lifestyle and wool coloration. In these features, marsh harelope is actually indistinguishable from the snow harelope. In spring and summer, the lifestyle and appearance of these species differ drastically. Marsh harelopes spend most of their time near the water or in the water, resembling ungulates that existed in the human era – marsh deer and antelopes. Siberian marsh harelope strangely combines the features of cursorial lagomorphs and wetland-dwelling ungulates.
During the spring flood, marsh harelopes can swim through flooded areas from one and a half to two dozen kilometers, and in summer they can even dive to feast on aquatic plants and escape from the gnats. They feed on a variety of aquatic and amphibious vegetation, are very fond of browsing berry bushes, and also adore mushrooms growing on rotten, damp stumps along rivers and in swamps.
Marsh harelopes are slightly smaller and weigh less than snow harelopes, which makes them easy to walk on marshy soil. The largest males are rarely larger than one and a half meters tall and heavier than 250 kg. Marsh harelope has a pronounced sexual dimorphism – the male weighs twice as much as the female. Ears are one and a half times shorter than those of a snow harelope. Unlike all other hoofed lagomorphs, marsh harelope has a longer movable tail with long hair (like a horse’s tail), which helps it at least a little to fend off annoying swamp midges, although it is not long enough to protect the body completely. Local birds help it to get rid of midges and horseflies.
The legs of this harelope end in sharp hoof-shaped claws on three widely spaced digits (the fourth digit does not reach the ground); under the digits there is a soft pad of elastic tissue that protects against injury. There is a strong skin membrane between the digits, the development of which is associated with its lifestyle. Hoof-shaped claws on the legs of the marsh harelope perform several functions at once: they are convenient for sticking to slippery soil on the shores of reservoirs, for walking on marshy soil and for digging out various plant rhizomes from the mud, as well as for protection from predators. In winter, the claws also help to move on slippery ice. In addition, by winter, the harelope’s feet expand due to the fringe of thick fur, which allows the animal to run easily on the snow, almost without falling through it.
These animals try not to defend themselves from predators actively, but to hide in the water. A swimming animal can reach speeds of up to 20 km/h. They are also able to run quite fast. In winter, the speed of movement of animals decreases, so in winter males and older females are ready to protect their family even from berl, rearing on their hind legs and fend off it with wide hooves of their forepaws, while making shrill and threatening calls. And if berl is at least a little full, then it prefers to retreat. When the predator is hungry, animals prefer to flee from it.
The animal’s summer wool is short and thick, similar to otter’s fur in texture. The background color ranges from dark brown to black with yellow transverse stripes on the rump, thighs and hind legs, as well as large yellow spots on the cheeks. Male grows a dark, almost black beard on its throat. The dark color and length of the beard are external indicators of the animal’s health. In winter, marsh harelopes grow long white fur.
Interestingly, males rarely fight for females. Females choose their own partners with darker and longer beards, avoiding mating with inferior males. These animals are much less aggressive than snow harelopes.
Families can consist of either a single couple or a harem with two or three females. Marsh harelopes mate in late autumn and early winter, and in late spring, the female gives birth to one, rarely two cubs. They are well developed, rise to their feet half an hour after birth, and by the end of the first day of life they can already run fast. On the second day of life, the cubs can already swim easily. The cubs resemble fawns in color, having small yellow spots all over their bodies. The cubs of marsh harelopes reach the size of adult animals in the second year of life. Young animals begin to reproduce at the age of 3 years, and their life expectancy reaches 30 years.
It is noteworthy that in particularly harsh winters, harems of marsh harelopes can gather in small herds, numbering from two to seven harems. In such event, the choice of the leader also takes place without conflicts. Males simply sniff each other, identifying the stronger and healthier by their scent, and they give up the role of leader to the strongest one without conflict. If there are males, who are approximately equal in strength, then they can push one another for a while, trying not to cause even the slightest harm to the opponent – whoever is the first to retreat in this peaceful duel, it concedes leadership to the opponent.
Despite their ability to defend themselves, in winter even the largest herd of marsh harelopes tries to stay close to large animals – usually to some family of shurga, trying to find protection from hungry waheelas, Siberian sabretooth or berl. And some of the herds of marsh harelopes go south in the autumn, into the forests, following obda herds.
Interestingly, on the border of the ranges of the snow and marsh harelopes, two related species can interbreed. It most often happens that marsh harelope females join the harem of a snow harelope male, but it also happens that a lone snow harelope female joins the harem of a marsh harelope male in the absence of a suitable partner and in order not to survive the winter alone, as this threatens death of starvation. In the case of such mixed breeding couples, unusual hybrids of the snow-marsh hare appear. Despite the affinity of these species, in such cases, male hybrids still turn out to be sterile (although being sexually active), but female hybrids in most cases turn out to be fertile, facilitating the exchange of genes between species.

Black-headed dwarf harelope (Lepolopella nigriceps)
Order: Hoofed lagomorphs (Ungulagomorpha)
Family: Harelopes (Lagolopidae)

Habitat: steppes of Central Asia (up to eastern coast of Fourseas) except for bush thickets.

Picture by Cossus

Harelopes have replaced in Neocene numerous hoofed mammals became mass species of herbivorous animals. Having developed plains, forests and woodlands, they were evolved to set of species with various appearance distinguished by different requirements in environment. In steppes adjoining to eastern coast of Fourseas black-headed dwar harelope, one of tiniest representatives of this group of animals, lives.
Growth of the dwarf harelope at a shoulder is about half meter. This is long-legged, fragile, gracefully build animal. Legs of this harelope end with sharp hoof-like claws providing excellent cohesion with ground at run (escaping from enemies dwarf harelope can accelerate momentum up to 60 kms per hour at short distances and also sharply change run direction).
Head of dwarf harelope is rather short and high, with strong chewing muscles: rigid graminoids made the basis of food of this animal. Living in dry and hot climate dwarf harelope has long ears penetrated with circuit of blood vessels which promotes effective cooling in heat.
Short wool of dwarf harelope is colored yellowish-brown with narrow close cross strips. Such colouring is consequence of special defensive strategy of dwarf harelope: having run any distance animal makes a long jump sideways and hides in grass having nestled to ground. Striped colouring reliably masks this harelope from predators.
Remarkable feature of colouring of this species is head parren – black head sides (areas around of eyes and cheeks). Nose bridge, nape, chin and throat are colored white. Such colouring of head helps animals to identify each other among grass and to support visual contact. Keen sight plays very big role in life of dwarf harelope: with the help of head movements animals can transmit signals to each other at big distances. If the grass is high, harelopes can even rear to support visual contact to the neighbour. At cubs head is colored the same color as body; only at approach of sexual maturity it gradually darkens.
Dwarf harelopes live in herds of 20 - 30 animals at wide grass plains with small thickets of bushes. There is no well defined leader in herd: the hierarchy is established by males only in short breeding season. Usually animals spend day in shadow of bushes and graze since evening till morning with short breaks for deep sleeping. And animals fall asleep by turns: a little from their number stay on the alert all the same.
For winter harelops migrate to the east away from Fourseas coast: during winter rains wool of animals can become wet that usually results in cold. And the ill harelope is easy catch for predators. In winter time rich underfur grows at them.
In the beginning of cool winter at harelopes the pairing season begins. At this time males become pugnacious and intolerant to each other. Rising they beat each other by forward legs, striking to opponent impacts by forward part of wrist. Such impacts do not harm fighting animal but at protection of the cub against small predator female can strike it direct impacts by hoof-like claws which can wound the aggressor seriously. However protection against the enemy with the help of hoof impacts is an extremely rare situation: usually dwarf harelopes seek safety in flight.
During courtship season males carefully sniff at all females finding ones ready to pairing. Such condition lasts at the female only some hours per year, and here it is important to use it in time. Male protects such female within day, repeating pairing some times. After the female will lose readiness for pairing and will cease to accept his carings, he searches for new females.
Pregnancy lasts about three months, then in early spring female gives rise to twin (sometimes even triplet) cubs. They are born very much advanced, with opened eyes, and after some hours are able to follow herd. At two-day age cub is equal in speed to adult animals.
Female feeds cubs with milk about 2 months, but already from week age the young growth starts to try forage of adult animals and change of diet passes gradually. At the age of eight months young animals get adult black-and-white colouring of head. They form independent herds and migrate to the east. At this time females become capable to pairing, and next spring they give rise to first litter. Males take part in pairing only one year later.
Life expectancy of black-headed dwarf harelopes is rather short and seldomly exceeds 10 years.

Japanese dwarf harelope (Lepolopella nipponica)
Order: Hoofed lagomorphs (Ungulagomorpha)
Family: Harelopes (Lagolopidae)

Habitat: Japan Archipelago, deciduous and mixed forests with dense undergrowth.

Picture by Cossus

In Eurasia, the fauna of ungulates became significantly impoverished in Neocene. This was due to anthropogenic pressure in Holocene and extensive glaciation at the turn of Holocene and Neocene. Only wild boars, whose descendants occupied the ecological niches of large herbivores, survived the era of the biological crisis relatively successfully. The role of small running herbivores was taken by representatives of a new group of animals – harelopes, the cursorial descendants of hares. These animals have become anatomical and ecological analogues of deer – gregarious fast-running herbivores of the ground level of the forest. This group is widespread in the Old World and inhabits Eurasia and North Africa. There are several small Asian species, and the Japanese dwarf harelope is one of them.
It is a relative of the black-headed dwarf harelope (Lepolopella nigriceps), a small, fleet-footed herbivore. The height at the withers of an adult is no more than 0.5 m. The animal resembles a musk deer in build – the hind legs are slightly longer than the front legs, which is why the back is slightly tilted forward. The muzzle is elongated; the ears are similar to those of a rabbit, covered with dense thick fur from the outside. The wool color in summer is plain brown, with variations from grayish to ochre-brown and even black. In the northern part of the range, the coat turns white in winter, while in the south it remains brown all year round.
Japanese dwarf harelope lives in small herds of 10-20 animals of both sexes and of various ages. There is no leader in the herd, and the hierarchy is not established. The animals are very careful; while feeding, several individuals constantly listen to the sounds of the forest and sniff the air, trying to detect the appearance of an enemy in advance. This harelope species keeps in dense forests, preferring shrubs and thickets of tall grasses. These animals usually hide from predators, freezing in place, and only run away when they are discovered. The alarm cry of this type is a sharp, jerky bark, very clearly distinguishable among the sounds of the forest.
These small harelopes are ecological analogues of small deer and do not compete with the shishigami (Gravicervus shishigami), a large local descendant of the muntjak deer. More often, their neighborhood turns out to be advantageous: harelopes and shishigami often graze together, and shishigamis protect harelopes from predators and in the north of the range, harelopes graze in winter on their dig sites.
In the spring, the female gives birth to two cubs. They are active from the first minutes of life and are able to run along with adults at the age of 1 day. The coloration of the young differs from the adult one: there are large white spots on the back of the ears; they disappear with age. Young animals reach sexual maturity at the age of 1 year. The life span of the Japanese harelope is about 10 years.
Related species live in the Far East:

Amur dwarf harelope (Lepolopella amurica) is a larger species, with a height of 0.7 m at the withers. This species is distinct in gray coat with dark spots on the back of the head, along the back and on the rump, and lives in lowland forests and wetland areas of the Far East. In winter, the coat coloration does not change. Digits have the ability to move apart, so that the animal can move through marshy swampy soil and swim.

Manchurian dwarf harelope (Lepolopella mandschurica) is smaller than the Amur dwarf harelope, with a height of 0.6 m at the withers. The wool color is gray with a dark saddle-shaped spot on the back and sides. This species inhabits the northeast of China, preferring mountainous areas. Claws with a very hard outer edge allow climbing on stone slopes. It does not compete with representatives of the closely related stonelopper genus (Lepotragus) due to its dwelling in the lower part of mountain slopes and in mountain forests.

Kurilean dwarf harelope (Lepolopella polymorpha)
Order: Hoofed lagomorphs (Ungulagomorpha)
Family: Harelopes (Lagolopidae)

Habitat: Big Kurils, mountain forests and thickets of shrubs.

Picture by Cossus

Eurasia of the Neocene epoch became the place of origin of hoofed lagomorphs, a special group of herbivorous mammals. They originate from the hares of the Holocene epoch and occupy the ecological niches of such different animals as musk deer and deer on the one hand, and musk oxen and mammoths on the other. Large hoofed lagomorphs represent a massive clade of the order, while harelopes represent a graceful clade that has achieved significant species diversity and has mastered various types of habitats.
The island chain of the Big Kurils is the habitat of one species of this group, Kurilean dwarf harelope. It is a close relative of the Japanese dwarf harelope (Lepolopella nipponica) from the forests of the Japan Archipelago, but differs from it in appearance features.
The most characteristic distinguishing feature of this species is its mottled coloration: a combination of a darker background and spots and large areas of lighter-colored wool scattered on it. Numerous small round-shaped spots are scattered on the sides. There is an area of lighter hair on the chest and belly, and a wide “smear” of the same color stretches from the nose bridge through the crown and nape of the neck. In general, the wool coloration is very variable: in the southern part of the population, it is light with a less contrasting pattern, and in the northern populations, the background color becomes darker (brown, dark gray, occasionally black individuals appear), and the spots turn white. Due to the long-term, but not complete isolation of various parts of the population, many local forms have emerged, that combine the characteristics of neighboring populations in various combinations – the shade of background color and light markings. In the summer wool on the back of adults, there is an area of elongated hair that hides the scent gland, which emits a faint musky scent. When moving in the undergrowth, males rub their backs against overhanging branches and leave their scent on them.
In winter, the differences between individuals from different populations become less noticeable, because this species changes its summer coat to a lighter one, which is white at the north of the archipelago. Winter wool is longer and thicker than summer wool.
This species has pointed hair tassels at the tips of its ears.
It is a small species – the height at the withers does not exceed 40-45 cm. However, the weight of adults is approximately equal to that of representatives of the more southern Japanese species: the decrease in size occurred mainly due to shortening of the legs. The hind legs are slightly longer than the front legs; that’s why the animal’s back has a noticeable forward tilt – this species lives in mountainous areas, and it makes more convenient to graze on the slopes. In case of danger, the animals run fast in dense undergrowth, and in areas with sparse undergrowth they move in long leaps. Frightened animals emit sharp, staccato screeching sounds.
Kurilean dwarf harelope inhabits forests and bamboo thickets, and is a common species of herbivorous mammals in these areas. This species lives in small groups of 10-15 adults of both sexes.
In spring, the female brings offspring: in the northern part of the range, one large cub is born, in the southern part twins are usual. The white spots on the cub’s coat are simply larger than those of adults. The cubs are active and able to run fast on the very first day of life. They are often fed in common by all the females in the herd – the presence of cubs stimulates lactation even in females, which for some reason are unable to produce offspring. Due to this adaptation, the survival rate of the offspring of this species is quite high. Young animals begin to eat vegetative food from about the second week of life. Puberty occurs at the age of 1 year, and life expectancy reaches 10-12 years.

Altai mountain lopper (Lepotragus altaicus)
Order: Hoofed lagomorphs (Ungulagomorpha)
Family: Harelopes (Lagolopidae)

Habitat: Altai, Tien Shan and Sayan mountains, mountain forests and meadows.

Picture by Cossus

Lagomorphs were a fairly successful group in the Holocene, although they lost some of their species after human domination. And in Neocene, they managed to take advantage of the anthropogenic environmental crisis and succeeded in breaking into a large-scale class, becoming the ancestors of a new mammalian order. Hoofed lagomorphs occupy the niches of extinct deer, antelopes and bulls of Eurasia and North Africa, and only in some places the persisting ungulates restrain their spread and compete with them. In the mountainous regions of Eurasia, this group of mammals is represented by a special group of mountain loppers – herbivorous animals of light build, closely related to forest- and plain-dwelling harelopes. The northernmost of their species is Altai mountain lopper, a close relative of the snowlopper and stonelopper.
Being a resident of the cold highlands, this beast is the largest among related species. The height of an adult animal at the withers is 1.25 m, the body length is up to 2 m, and the weight is about 130 kg. This beast has a massive body with a relatively long, mobile neck and a small graceful head and thin but strong limbs. Instead of hooves, short thick claws grow on its digits; the beast supports on the end phalanges of the digits, under which soft pads of connective tissue grow. Wool is thick, dark gray-brown in color, the tip of the muzzle and the lower part of the body are of lighter color. After the autumn molt, the animal gets a snow-white coloration. In males, during the mating season, a “mane” of white or creamy (in the Tianshan subspecies Lepotragus altaica tianshanica) hair grows on the underside of the neck. Tail is very short.
This animal forms herds of 25-30 individuals and lives mainly on mountain meadows and plateaus, only descending to the forest border for the winter. And only some herds enter the forest itself. Altai mountain lopper feeds on grasses, leaves and branches of shrubs, browsing them among the stones with the help of its elongated narrow muzzle. Altai mountain lopper is very cautious; at any moment it can rush to the steepest cliffs, scree or tall stones.
The mating season begins in the second half of winter. At this time, males fight for females, arranging tournament fights with their front legs. But first they bleat and shake their heads, displaying their manes, then, like a snowlopper, they stand on their hind legs and walk for several steps in this position. At the end of the breeding season, the herd is divided into harems of one male and 3-5 females, which he protects from rivals. Bachelor males stay in small groups or singly.
Two well-developed cubs with opened eyes are born in early summer, when food is plentiful, and from the very first days of life they taste the food of adult animals. They are fed by all nursing females of the herd, which significantly increases the probability of survival of the young, even in the event of loss of the mother, and also does not exclude from breeding females who have lost a cub in a given season for some reason. By winter, the cubs become completely independent, although they stay close to their parents. In the parent herd, they spend their first winter, but by the spring of the following year, the young animals leave the herd and go away, gathering in bachelor groups or joining other herds. Usually, females join the harems of adult males, although sometimes they form small herds of the same age. Puberty begins at the age of 3 years, and life expectancy reaches 20-23 years.

African marshland harelope (Xenoheterolopa palustris)
Order: Hoofed lagomorphs (Ungulagomorpha)
Family: Harelopes (Lagolopidae)

Habitat: freshwater reservoirs in the northern part of Africa, Saharan Nile and lakes in its basin.

Picture by Cossus

Harelopes are animals having very high adaptive abilities. Natives of the Eurasian forest zone, they managed to conquer the cold circumpolar regions (snow harelope), as well as the southern expanses – the steppes of Asia and the African savannahs, and even settled in deserts of North Africa. African marshland harelope has evolved in a different direction.
Marshland harelope is one of the most unusual representatives of this family. It is one of the few species of hares that have developed sexual dimorphism independently of the polar forms of Heterolopa genus (hence the generic name). Males are much larger than females: they reach a height of 120 cm at the withers and weigh over 100 kg, while the height of the female at the withers does not exceed one meter, and she weighs almost half as much. In addition, they are colored differently: males are dark brown, females have a noticeable ochre tinge, and cubs and yearlings are of chestnut color. Belly is always brownish yellow. Despite this difference in appearance, both males and females of marshland harelope are social animals, and often several families graze together, especially during the rains, eating various aquatic or amphibiotic vegetation. They are capable of eating some poisonous plants.
Marshland harelope is one of the most water-loving species in its family. Its fur is covered with water-repellent secretions of modified sweat glands – the animal spends a lot of time smearing secretions on its fur with its muzzle. Due to this grease, the wool does not get wet from contact with dirty wet coastal vegetation, where this animal hides from enemies – large predatory African beasts. Its coloration, bright and noticeable in the open, perfectly hides the beast in the shade of thickets of papyri and other reeds, etc. Living in thickets of plants, marshland harelope is guided mainly by hearing: she has a keen hearing sense even among the members of the family, and its ears are very large for an aquatic animal. There is no safety valve in the ear canal, so this animal does not like to dive, and does so only if absolutely necessary. The eyes and nostrils are shifted to the upper part of its head.
It swims and walks on marshy ground well: its digits are large and widely spaced, connected by a membrane at their base. The hooves are wide; this makes marshland harelope rather clumsy on solid ground, but it swims almost silently and can swim away from almost any enemy, with the exception of the largest ones: crocoturtles and large water monitors, which attack it from underwater and drown the captured prey.
The mating season of the marshland harelope occurs at the beginning of the rainy season. This animal is not territorial, but males gather and guard their own harems of females. Fighting for the females, they stand side by side and push each other with their shoulders, trying to knock down the opponent. The winner gets the entire harem of females, and it depends on his own behavior how successfully he manages to keep the females. This species is not monogamous, and each female can easily mate with several males. The male does not take care of the cubs, leaving it to the female to do it; he also does not drive away the grown-up cubs, which leave the parent group themselves and go to meet their own fate. They become sexually mature very soon: females at one year of age, and males at one and a half years. African marshland harelope can live up to 20 years or a little more, but most of these animals die much earlier.

Hare-elk or Handagai’ (Lepoalces handagai)
Order: Hoofed lagomorphs (Ungulagomorpha)
Family: Harelopes (Lagolopidae)

Habitat: Siberia, riverbanks, lake coasts, vast swamp marshes.

Picture by Cossus, processed by Alexander Smyslov

Hoofed lagomorphs form a new group of herbivorous mammals, whose representatives clearly fall into two size classes – small gracile harelopes and very large slow-moving herbivores – obda, umingmak and lagomoropus. Among the harelopes, the largest species is the Siberian handagai’, or hare-elk, a relatively rare species of hoofed lagomorphs. The species shares common ancestors with Siberian heterolopes. Despite the almost complete overlapping of their ranges and the frequent cases of meetings and joint feeding, due to the difference in size and genetic differences, these species have actually lost the opportunity to interbreed. There are only few cases when runty young single handagai’ males can mate with a large single female of marsh harelope, but, as a rule, the offspring from such a union turns out to be sterile – only in one out of a hundred cases a fertile female may appear.
In the course of convergent evolution, hare-elks began to look a lot like true elk. The second name of the animal – handagai’ – means “elk” in the Buryat language. The male’s body length is up to 3 m, height at the withers is up to 2.5 m, and weight reaches 500-700 kg. The length of the tail is 15 cm, not counting the length of the hair on the tail (10-20 cm). The female is smaller than the male, with a body length of 2.5 m, a height at the withers of up to 2 m, and a weight of 350-450 kg. The tail length in females is 10 cm (plus hair 7-10 cm). In appearance, the hare-elk is noticeably different from other harelopes. Its body and neck are short, its withers are high, looking like a hump. Legs are long, so in order to drink, hare-elk has to go deep into the water or stand on bent forelegs.
The muzzle of hare-elk resembles an elk muzzle in shape, although it has not lost its hare-like features, for example, the upper lip is like in hares, not elks. The head is large and hawk-nosed, vaguely resembling the head of an obda. Male has a long black beard. Wool is slightly longer and rougher than that of the marsh harelopes, and its color is much duller − various shades of black, from brownish-black to raven-black. At the same time, its legs are light gray, almost white; there are hardly distinct dark brown stripes on the rump, thighs and hind legs, and there are large, but also faintly distinguishable, dark brown spots on the cheeks. In cubs, these stripes and spots are more noticeable – they are light red; with age, the coloration of the animal fades. In winter, handagai’ grows long, warm white fur.
Unlike all other harelopes, males tend to butt for females during the rut, as well as for contested territory during other periods. Therefore, handagai’ male has two large lumps of keratinized skin on its forehead. In especially large males, these lumps protrude from the fur and look like very short, blunted horns. Females have no lumps on their heads. The animal’s ears are elongated, covered with thick hair on the outside. The “hooves” of handagai’ are very similar to the “hooves” of marsh harelopes, but the sole is much wider.
Hare-elks inhabit willow thickets along the riverbanks and lake shores. Of great importance for hare-elks is the presence of swamps, slowly flowing rivers and lakes, where in summer they feed on aquatic vegetation and hide from the heat. Hare-elks have no specific periods of feeding and resting. In summer, the heat makes them nocturnal animals, driving them during the day into clearings where the wind blows, into lakes and swamps where they can hide up to their necks in water, or into young coniferous forests, which protect them a little from insects. In winter, handagais feed during the day, and at night they stay on lair almost all the time. In severe frosts, animals lie down in loose snow so that only their heads and withers stick out above them, which reduces heat transfer. In winter, the hare-elk tramples the snow heavily on the resting place. The location of their resting places depends on the places rich in forage.
Hare-elks feed on woody-shrubby and herbaceous vegetation, as well as mosses, lichens and fungi. In summer, they eat the leaves, reaching them on a considerable height due to their growth, and feed on tall grasses – willow wort and sorrel – on burning grounds. In summer, a significant part of the diet consists of aquatic and amphibious vegetation (water lilies, horsetails, etc.). During the spring flood, handagais can swim through flooded areas, easily overcoming from one and a half to two dozen kilometers, and freely dive underwater to find something edible. They can stay underwater for up to 5-7 minutes, thanks to the tightly closing nostrils.
At the end of summer, handagais search for pileate fungi, fruiting berry bushes, from September they begin to bite off shoots and branches of trees and shrubs, and by November they almost completely switch to browsable forage. The main winter forages of handagais include willow, pine, aspen, mountain ash, birch, raspberry; in the thaw they gnaw the tree bark. An adult handagai’ eats about 35 kg of feed per day in summer and 12-15 kg in winter. During the period of winter starvation, the animal loses weight significantly.
Handagais run fast, reaching speeds of up to 56 km/h. They defend themselves from predators by striking with their forelegs and hind legs, and also bite, causing extensive lacerations. The beast is quite strong, and therefore even berl and tanooka do not dare to attack a male handagai’ in an open area. As a rule, predators attack them among the bushes so that the handagai’ is limited in movement. Of the senses, the hare-elk has the best developed hearing and sense of smell; the eyesight of hare-elk is weak.
Males and non-breeding females live alone or in small groups of 3-4 animals. In summer and winter, adult females walk with their cubs, forming groups of 3-4 individuals. Sometimes males and single females join them, forming a herd of 5-8 animals. In the spring, these herds break up. In winter, marsh harelopes sometimes follow a herd of handagais at a respectful distance, hoping to find something edible under the snow excavated by handagais. When predators appear, frightened harelopes warn handagais, who have poor eyesight, with an alarm call.
The rut of hare-elks takes place in September-October and is accompanied by the characteristic dull roar of the males. During the rut, males and females are agitated and aggressive. Males fight, kicking and butting each other, sometimes to death. For the first some years of life, until the male has chosen a permanent female, he can mate with various single young females, but over time the males find a permanent companion, which they do not leave for the rest of their lives.
The pregnancy of handagai female lasts 225-240 days, and calving lasts from April to June. There is usually one cub in a litter; large, healthy females can give birth to twins. The newborn’s coloration is light ochre-red, changing to mottled over time. Cubs can stand on their feet within a few minutes after birth, and move easily with the herd after 3 days. Milk feeding lasts 3.5-4 months; milk is very fatty and contains a large amount of protein, so the young grow up significantly by winter.
Handagais become sexually mature at the age of 2. After 15 years, the hare-elk begins to grow old; only large, strong males live up to 20-25 years, but at this time they actually do not take part in reproduction.
There is a very high mortality rate among the young: almost half of the cubs die from the teeth of predators and from frost in winter. Sick and old animals also die from predators. Epizootics often occur due to tick-borne infections. But handagais have reliable friends saving them from ticks, such as the Siberian woolcreeper and the obda bat.

Australian marsh rabbit (Aqualagus natans)
Order: Lagomorphs (Lagomorpha)
Family: Hares (Leporidae)

Picture by Carlos Pizcueta (Electreel)

Habitat: rivers and bogs of Eastern Australia.
During all Cenozoic in Australia marsupial mammals dominated. Due to absence of competition they had occupied practically all ecological niches with one exception. Because of features of cub bearing process marsupial mammals principally can not develop water habitats. Only in South America the water opossum (Chironectes minimus) had appeared but it had developed water habitat not in that degree as, for example, otter or seal. But activity of people had resulted in occurrence in Australia of big number of placentary mammal species. In Neocene among descendants of these animals one species successfully occupied Australian waters had appeared.
The place of water predator in Australian ponds and rivers was shared among different predatory reptiles. But the place of water herbivorous analogue of beaver and musk rat was earlier vacant. It was occupied by Australian marsh rabbit – descendant of rabbits introduced by humans. This small mammal had kept rather recognizing appearance characteristic for rabbits though it has got some adaptations to unusual habit of life.
This animal is able to swim perfectly and even to dive for 3 – 4 minutes. Strong hinder legs are adapted to swimming: feet at them are wide. Usually this rabbit swims having pressed forepaws to sides and making sharp simultaneous movements by hinder legs. Ears of marsh rabbit are short and rounded, they can close lengthways. Fur is short and rigid; it is white on stomach and cheeks and brown on sides and head. Along back some faltering dark stripes pass. Tail is short, white from wrong side.
Marsh rabbit eats leaves and tubers of water plants. Usually it foods in thickets of marsh grasses but in case of necessary can dive to the bottom for tubers of plants - arrowheads and aponogetons. Having dived marsh rabbit digs out tubers by forepaws. Its ears thus are folded and pressed to shoulders.
Dwelling of this original rabbit is the hole in steep river bank. The entrance to the hole is placed above maximal water level in the river and usually is disguised. Holes of different individuals are united to one system and stretch along river bank to tens meters. The settlement of marsh rabbits usually appears in place where there are shallows with thickets of water plants and reeds.
In rabbit holes other animals, usually birds and small lizards, frequently settle.
Settlements of Australian marsh rabbits include usually no more than one and half tens of adult animals – food resources of river are more limited than in places where rabbits lived earlier. Three - four times per year number of colony considerably grows: at does posterity appears. Usually first time doe of this species rises posterity being half year old. In litter usually there are four - five cubs. It is less than at rabbits introduced to Australia by people, but newborns of water rabbits are larger and also develop much faster. At fortnight age young rabbit cubs start to investigate world around. They leave a hole and gradually start to try plants eating by adult animals. Rabbit cubs very cautiously investigate water and make first attempts to swim. It is the most dangerous moment in their life – numerous predators – turtles, snakes and fishes hunt for inexperienced young mammals not able to swim quickly. And at any age predatory birds are dangerous to marsh rabbits and it is possible to escape from them having dived or having hided in hole.
These animals feed in shallow waters having hided among leaves of marsh plants rising above water. Because in this case the field of vision is limited at marsh rabbits the system of sound dialogue is advanced. Resting rabbits communicate with the help of short clicks. Having noticed the predatory bird flying by above thickets rabbit utters shout of alarm – prolonged chirring. Having heard this signal animals try to dive or hide under driftwood. To signal about the underwater danger marsh rabbits have other signal – shrill whistles.
Despite of care and collective system of enemy watching hardly probable tenth part from number of newborn rabbit cubs lives up to adult condition. And life expectancy of adult rabbit seldomly exceeds three years.

Common Australian rabbit (Australagus papiliotis)
Order: Lagomorphs (Lagomorpha)
Family: Hares (Leporidae)

Habitat: Western and central Meganesia (up to the eastern coast of Eyre gulf and the zones bordering with the tropical rainforests at the north), various types of biotopes, from dry savanna to temperate forest.
In late Eocene epoch, the southern remains of the large continent of Gondwana broke in two great landmasses, Antarctica, and Australia, initiating the drift of this enormous island to the north. As the result of many millions of years of isolation from mainland, the Australian fauna became quite extraordinary and unique; some of the most unusual creatures in the Cenozoic evolved here. During late Holocene, the structure of this original fauna had considerably changed, due to human activity: whereas many endemic species of this subcontinent have disappeared, other ones, specially placental mammals were delivered from other zones of the Earth. The introduction of foreign mammals in the historic time, was in many cases more catastrophic than the direct action of human for the native marsupials: then, kangaroos and other small herbivores had to compete for food with enormous herds of sheeps, goats and rabbits, that eventually desertified great areas of terrain. Foxes, dogs and cats, also competed with local predators, and affected to the population of small marsupials and birds, by hunting them.
Though after the extinction of man, some of these ecological “aliens”, like the placental carnivores, were eliminated by epizooties, others, for example, dromedaries, rodents and rabbits, successfully adapted to the conditions, and started to evolve, filling the left niches. Due to this event, Australian mammal fauna during Neocene is a mix of three different stocks; most of the placentals are constitued by herbivores; the descendants of dromedaries diversified into various new species occupying many of the niches, nevertheless, there are also several herbivorous marsupials, some of them reaching a great size. Species of monotremes are not the most common creatures, though they’re more numerous than during Holocene. Predators are basically marsupial; and the small and medium sized ones usually prey on the ubiquitous and typical rodents and rabbits.
During the Holocene, the European rabbit (Oryctolagus cuninculus) was intentionally introduced in Australia by the people. The propagation of these creatures occurred incredibly fast and within some years they expanded almost to the whole subcontinent, becoming a serious and uncontrollable plague affecting both humans and native animals. Rabbit species successfully survived after the extinction of man and endured the ecological accident that started to the Neocene epoch, becoming one more important element in the local fauna... and the food chain.
During Neocene, Australian rabbits diversified into many species, occupying some niches, some of them even leading a semiaquatic type of life. However those species, still quite recognizable, they have kept the small size and the typical shape of their ancestors. Because of the tendency of the ecosystems to rearrange with the pass of the time, the population of rabbits is not so large as it was during the historical time, it is controlled by the small predators that usually prey on them.
Many of the species are contained in the new genus Australagus, that literally represents the adaptation of rabbits to the different habitats in Australia. The most abundant and less specialized species of the genus is the common Australian rabbit. Body length in adult individuals is about 40-60 cm. Like all its relatives, the Australian rabbit is quite similar to a normal rabbit, and differ in very few aspects, nevertheless those species are quite remarkable due to a feature that distinguish them from other lagomorphs. They possess typical rather long and mobile ears, but when we look at their internal side, it can be appreciated that an original pattern of speckles and oculate spots is scattered. This special pattern, that vary in each species of the genus, quite remembers the colouring pattern of butterfly wing. That determines the specific name of the common Australian rabbit, A. papiliotis, which means “butterfly eared”. Ear colouring pattern in these species is less advanced than others, but still it’s very captivating: internal side of the ear is white, on it a great amber coloured oculate that seems an eagle’s eye appears, there are also some dark speckles of different shapes, including a stripe bordering the oculate spot by one side. This remarkable colouring feature is a quite important element in the social behaviour of the rabbits, used mainly in rituals and for recognition within neighbours, though in some cases it can serve for frightening off predators. Ears can easily be stretched widely, inclined to sides and folded back thanks to special nerves on them and advanced muscles on their basis. Body colouration of the Australian rabbit is yellowish brown with some dark spots at the sides, head, back and paws are darker, stomach and tail are white. Around eyes there’s a white spot; bordering it and along the nose bridge there is a black mask.
The common Australian rabbit has a wide diet range, it feeds on various types of aliments, from grass, leaves, bush branches, roots, up to insects. As well as its ancestors, Australian rabbit is a social animal living in colonies of tens of individuals, in great, complex burrows that expand with the pass of generations. The community is divided in social differentiated casts: there are some dominant individuals, and various types of subordinates. While the rank of the dominant females is immutable, in the case of males is constantly changed. Cada certain period of time, in the colony, a ritual for the hierarchical reestablishment is realised. In it, mature males flap their ears, and show the intern colouration to their opponents. Those who have the most expressed pattern become accepted by the dominant females.
6 times per year, females bring posterity to 8 blind, defenceless cubs. Dominant females nest in the principal burrow, whereas the subordinated ones have to do it in separated chambers.
When it’s reached a certain number of individuals, the overgrown colony has to be divided into two groups, one stays in the burrow, and the other leaves, searching for a new place of inhabiting.
Some more specialized relatives are adapted to different habitats:
Mountain Australian rabbit (Australagus orophilus) inhabits the eastern mountains up to the Great Dividing Ridge. It differs in greater size (adults can grow up to 70 cm of length), strong constitution and quite small ears. These species are adapted to life in the rigorous cold mountain habitats, they have broad feet with slightly cornificated skin under them for jumping and skipping easily on the rocks without receiving any harm. Fur is rich and fluffy, general body coloration changes seasonally, during the winter is light grey, whereas in summer it acquires a brownish shade. On the back some great longitudinal dark stripes are stretched, stomach is white. Ears in these species are rather reduced and rounded, an adaptation for living in cold conditions. Nevertheless the typical ear pattern has not disappeared: A great yellow oculate with a black spot in the centre almost occupies the whole ear, and some round dark stripes surround it. It feeds on whatever edible that could find, including seeds, little bush branches and moss.
Forest Australian rabbit (Australagus sylvaticus) Similar to the common species, though it is a bit smaller. Lives in woods and rainforests at northern and eastern Meganesia. It possesses a contrasted coloration: top part of the body is rusty brown with small light speckles, and stomach is white, both head and paws are very dark brown. On cheeks and around eyes there’s a zone of white hair. In these species, the colouration pattern of the ear characteristic of the genus is taken to extreme level: a myriad of speckles and stripes and an oval oculate of pink colour in the interior part of the ears, and a fringe of reddish long hair on their top edges, form a spectacular, matchless ornament.
The forest Australian rabbit feeds on the various wood plants, bark and fruits and nuts that fall from the trees.

Desert Australian rabbit (Australagus lepoides) These species living in the arid zones at the southwest part of the subcontinent resemble hares in many respects, especially due to their slender constitution and long ears. This form is adapted to the extreme conditions of the desert. It possesses rather long feet for racing in the sand. Quite long ears (up to 20 cm), are penetrated by a circuit of blood vessels; that serves for radiating the harmful heat. Fur is short and velvety, coloured very light yellow. This colouration helps it both to camouflage on the terrain and reflect the intense sunlight, avoiding so the overheat. The sole dark zones are two speckles over the eyes and the external part of ears. The ear pattern is rather degenerated, only some simple faltering stripes and an elongated red coloured oculate appear. It feeds mainly on grasses and roots, but during the severe drought season it can survive gnawing little dry branches and even pecking on carrion.
Colonies of this species are quite small, each one is constituted by less than ten individuals.

These species of mammals were discovered by Carlos Pizcueta.

Giant lake rabbit (Barocuniculus capybaroides)
Order: Lagomorphs (Lagomorpha)
Family: Hares (Leporidae)

Habitat: marshlands around Carpentary Lake.

Picture by Pavel Volkov

Evolution has given one serious limitation to marsupial mammals: due to their mode of reproduction they are almost completely unable to develop an aquatic lifestyle. Therefore, in the territory of Meganesia in the Neocene epoch aquatic mammals belong to two other groups. These are various platypi feeding on small aquatic animals and rabbits, having become herbivorous animals.
Giant lake rabbit is one of aquatic species of rabbits inhabiting the coastal zone of Carpentaria Lake, preferring wetlands with dry islands and extensive thickets of marsh vegetation. This species of rabbit in the process of evolution has acquired a significant convergent similarity with the capybara, South American caviomorph rodent. This is a large herbivorous creature with broad paws and sparse rough wool. It has almost lost the ability to jump: on land this animal moves on outstretched legs, and only being in water it can push off with both feet at once. Feet of the animal have elongated toes, which are connected by a thick swimming membrane. The height of the adult at the shoulders is up to 40 cm, the weight is about 10 kg. In spite of the adaptation to an aquatic lifestyle, this animal is able to run fast over short distances, but prefers to hide from enemies in the water.
The coloring of its wool is gray with a white belly and a white spot on the neck and shoulders, which prevents a predator to recognize the true contours of the body. The area around the nose, the tip of the lower jaw and the cheeks are white. The rear part of the body is darker than the front, and under the tail there is a vast area of white wool. In case of alarm the animal lifts its tail and shows this spot. Giant lake rabbit has large head with long whiskers and powerful incisors. The ears are very short, with a valve inside that protects the ear canal from water. The nostrils can close also. The eyes are large, shifted to the top of the head.
This animal is a good swimmer; while underwater, it paddles all its legs alternately, while swimming near the surface of the water. If it needs to dive, this animal paddles its hind legs at the same time, holding its front legs on its stomach. The basis of the diet is made of aquatic plants. Also this animal eats coastal vegetation and tree seedlings in boggy areas of forests. With the claws of its forepaws the rabbit digs up roots and tubers at the bottom of the lake and eats them on the surface of the water. In case of danger the animal dives and can stay underwater for up to 5 minutes at a depth of 5-6 meters.
It is a social species of animal, which settles in small groups of 2-5 breeding pairs on dry islands in the marshes. Each pair of adult animals digs a burrow under tree roots, a well-trodden path leads to the water among the vegetation. The depth of the hole can reach 5 meters. The pair of adults bear cubs 2 to 5 times a year. The cubs stay with their parents up to 3 months, and then leave the parent group. They lead an independent life in small groups which settle on the banks of rivers and swamps. Typically, these groups give rise to new settlements. Sexual maturity comes at the age of 4 months.
The life span of adult animals rarely exceeds 7 years. Enemies of this species are large reptiles (for example, the giant snake eingana (Eingana archonta)) and birds of prey.

The idea about the existence of this species of mammal was proposed by Tim Morris, Adelaide, Australia.

New Azora tardolagus (Tardolagus novazorae)
Order: Lagomorphs (Lagomorpha)
Family: Hares (Leporidae)

Habitat: woods and bushy thickets of New Azora.

Picture by Amplion, colorization by Lambert

Initial image by Amplion

In human epoch the fauna of islands had undergone changes: various species of flora and fauna which could not appear at these islands by natural way had been introduced to islands. Occurrence of these species has broken natural balance of island nature, and ecosystem began to develop another way. New species of animals, descendants of introduced species, had taken the place in these ecosystems.
People had introduced rabbits to Azores (and to other numerous islands of the Earth). These animals had survived in epoch of global ecological crisis and evolved to species being a part of new ecosystems of Neocene. At the volcanic island New Azora very large species of ground herbivorous animals had appeared, the descendant of rabbit – New Azora tardolagus. It is the largest species of terrestrial (not connected to sea) inhabitants of island. Tardolagus represents herbivorous mammal weighting about 50 kg. By proportions of body this animal resembles various herbivorous mammals evolved at the continents – fossil chalicotheres (Chalicotherium), megatheres (Megatherium) and Neocene animals - ndipinotheres (Ndipinotherium)and groundsloth rodents (Tardimegamys). Tardolagus has long forepaws and inclined back. Due to “semi-bipedal” constitution tardolagus can rise on strong hinder legs with wide feet and gnaw branches of bushes and undersized trees. Standing on hinder legs, this animal reaches growth of one and half meters. During the feeding it tightens branches by forepaws on which large hooked claws grow, a little bit similar to claws of ground sloths. At movement on four legs the animal bases on external side of hands, turning claws by tips to each other. Because of massive constitution tardolagus moves walking (its name literally means “the slow hare”), and only in case of danger can run on small distances. Martillas, large local predators, represent the main danger to this animal. Tail at tardolagus is very short, long white colored hairs grow on it.
Wool on back, sides and hips is reddish-brown with dark spots forming faltering longitudinal lines. Lateral parts of head are white, tip of muzzle is dark. Forepaws from claws up to half of forearm are colored white.
Tardolagus eats rather soft forage – leaves, mushrooms and fruits of plants. Its muzzle is extended, and forward incisors are rather weak. The animal willingly eats dropped fruits of trees of laurel and heaths families, and with the help of claws digs out roots of ferns and other plants.
This animal meets in places overgrown with bushes and undersized trees – at riverbanks, in gorges and mountains of island. It avoids the areas overgrown with woods of tropical type with poor underbrush, where there is small amount of food. Tardolagus keeps in small groups of about ten adult individuals and young growth. This animal had strongly changed habit of life in comparison with ancestor: it had lost the ability to dig holes, and only makes beds in bush, or uses natural shelters to spend the night.
At danger tardolagus prefers to protect itself actively – it rises on hind legs, bites and beats the aggressor by long claws of forepaws. Thus it growls and opens mouth, showing incisors.
Breeding rate at tardolagus is very low in comparison with ancestor. This animal brings posterity once a year. At female one or two large cubs are born. They are more advanced, than newborn rabbit cubs, but not so advanced, as posterity of hares. For birth of posterity female leaves the group and searches for shelter for itself and posterities. The newborn cub of tardolagus is covered with dark wool, but blind and can not stand. Till first days the female hides posterity in shelter – in cave or among bushes. The cub develops quickly: at the second day it opens eyes and starts to explore world around. At week age the cub already is able to walk. Grown up cubs leave shelter and follow mother to join the group of congeners.
Young tardolagus begins able to bring posterity at the age of three years. Life expectancy of this animal is till 20 years.

Falkland xenolagus (Xenolagus subantarcticus)
Order: Lagomorphs (Lagomorpha)
Family: Hares (Leporidae)

Habitat: Falkland Islands, flatland and mountain areas overgrown with grassy vegetation.

Picture by Alexander Smyslov

Studying of the biosphere of Earth of Neocene epoch indicates that in various places of the planet there are animal species which couldn’t appear in those places in natural way. Their existence is the result of human activity in casual or purposeful introduction of species. Actually, human activity broke the natural isolation of these or those districts and changed the course of evolution of the species making ecosystems.
At Falkland Islands during the historical era there were no large herbivorous mammals, and on islands the special type of tall grassy vegetation – tussock – developed. In Neocene the vegetation of islands looks otherwise: the grassy cover doesn’t reach great height and forms continuous extended turf. It is so because the large descendant of introduced rabbit – Falkland xenolagus lives on islands.
Xenolagus is very large species of lagomorphs: its weight reaches 30 kg and more. Xenolagus has heavy constitution: it is four-legged animal with large head and rather short plantigrade extremities. Unlike rabbit, xenolagus isn’t able to jump, and in case of need it runs gallop, rising on finger-tips. The body of animal is covered with dense fur which changes color depending on seasons. In summer the body coloring of xenolagus is grayish-brown with dark chestnut strip stretching on head, neck and along the back. Throat of animal is white; white coloring sometimes stretches on breast and stomach. In winter fur hair of animal are longer and colored lighter.
Life in cool Subantarctic climate led to reduction of the sizes of projecting parts of animal body. Xenolagus has short rounded ears capable to turn in various directions. The outer side of ears is black; on the base of ears there are white strips. Ears risen up become appreciable – it is an alarm signal. Tail of this animal is also short and covered with fluffy wool, white from the bottom side.
Xenolaguses are the sociable animals settling and feeding in common. Because of large size these animals need the considerable territory for feeding; therefore settlements of xenolaguses include no more than four or five pairs of adult animals and their posterity. For housing xenolagus digs wide holes up to 5 meters deep, ending with the living chamber. In holes of these animals flightless sea birds cavescars often settle and dig for themselves lateral tunnels opening in main tunnel. Holes of representatives of the same colony are located in the neighbourhood, at distance of several meters between them. Animals from different pairs know each other by smell and treat to “friends” rather tolerantly. Breeding pair at this species is formed for one season of reproduction and breaks up to the next courtship season; the hole is in possession of a female. Often happens so that males of different pairs during new courtship season simply move to another hole within the colony. The newcomer from outside should graze any time in common with representatives of the colony that they got used to its smell and presence. Usually young males move from one colony to another, whereas females born in the colony dig their holes near parental one or occupy the free holes in colony.
Due to size enlargement and increase of survival rate of posterity rate of reproduction of xenolaguses became much slower, than at their ancestors. Once a year female of this species gives rise to the litter of 4-6 cubs. The newborn xenolagus weighs about 300 grams, but quickly gains weight and in two weeks weighs about one kilogram. The newborn individual is covered with wool, but eyes and ears open only at the end of the first week of life. The young animal starts to pass to adult diet gradually at the age of 3-4 weeks, but stops the milk feeding only at two month age.
The sexual maturity comes at the first year of life; in litter of young female it may be only 1-2 cub. Life expectancy reaches 20 years.

Steppe hare (Lepus balchashensis)
Order: Lagomorphs (Lagomorpha)
Family: Hares (Leporidae)

Habitat: steppes of Central Asia from the Fourseas to Lake Baikal.
Numerous and fast-breeding, hares survived the human era with fewer losses than many other animals. During the post-anthropogenic crisis, some of them managed to take advantage of the extinction of large herbivores and break out into a large-sized class, forming a new order of hoofed lagomorphs. However, along with these specialized forms, hares of a more familiar appearance exist in Neocene. One of them is the steppe hare, a descendant of the tolai hare (Lepus tolai).
It is a fairly large hare species: body length is 65 cm; body weight is up to 7 kg. The increase in body size had taken place due to the avoidance of competition with actively evolving rodents in the small-sized class. The wool color is gray, and the head is black; in winter, the wool is lighter and longer. Steppe hare is quite tall-legged, which helps it look over the grass, and it often walks on four legs. It is a solitary and territorial mammal. Depending on the food abundance in its habitat, it can constantly stay in the same area measuring from 30 to 50 hectares, protecting it from competitors. By so doing, the owner of the territory makes high jumps or kicks, forcing the stranger to retreat. In the heat, the steppe hare is active at dusk, for the rest of the year, it feeds during the day. Its main food is the green parts of plants, as well as roots and bulbs, which it can dig up from a depth of 20-30 cm. In winter, steppe hares sometimes follow large animals, using their dig sites to get some food. Its natural enemies are birds of prey, snakes, canids and zibetonyx.
The mating season lasts from March to September; during this time, about 75% of the females manage to bring 4 broods. 3-5 males chase the female, and fights break out between them, often accompanied by a high-pitched scream. Pregnancy lasts 45 days, and a few days after giving birth, the female is ready to mate again. There are usually 4-6 cubs in a litter, depending on the weather conditions and the age of the female. Before giving birth, females make primitive nests out of grass, and often use natural shelters. Cubs are born sighted and covered with fur, weighing 80-150 g. The female comes to feed her offspring once a day, and sometimes after a day or two. From the 5th day of life, the cubs begin to move near the place of birth; by 2 weeks they reach a weight of 300-400 g and already actively eat grass, and at the age of 3-4 weeks they become independent. There have been cases of hare female feeding cubs of any other female, if they are of the same age as her own ones. Puberty begins next spring, and life expectancy is 12-15 years.

Great Crimean hare (Megalepus longipes)
Order: Lagomorphs (Lagomorpha)
Family: Hares (Leporidae)

Habitat: Fourseas, island of Crimea.

Picture by Pavel Volkov

In Neocene, the evolution of hares in the Old World gave rise to a new order of herbivorous mammals, the hoofed lagomorphs (Ungulagomorpha). The appearance of these animals became possible due to the depauperization of Eurasian ecosystems as a result of human activity. The lineage of large lagomorphs, leading to representatives of this group, distinguished itself in the early Neocene as a line of very large “true” lagomorphs, adapted to varying degrees to fast running and feeding on the leaves of shrubs and small trees. Representatives of the archaic hoofed lagomorphs and their ancestors from among the “true” lagomorphs became extinct in Eurasia, superseded by more progressive harelopes and titanolagids, but one of the relict representatives of this group managed to survive on the small island of Crimea, isolated by the waters of the Fourseas – this is great Crimean hare, one of the few species of local herbivores.
This lagomorph species is a relic of the early stage of the evolution of lagomorphs, which later led to the evolution of the hoofed lagomorphs. In fact, it’s just a very large hare with long legs and an elongated neck, resembling a cross between a true hare and a harelope. The legs of this animal are not specialized, the digits are connected by skin and retain pads, and the claws are only slightly thickened and blunted compared to typical hares. The bones of the digits do not fuse and remain mobile. This animal moves on elongated legs of approximately equal length, supporting only on the tips of its digits. The height of an adult representative of this species is about 70 cm in the shoulders, and the weight is up to 20 kg. The males of the great Crimean hare are larger than the females.
The animal has a movable neck, which allows it to feed both on grass and leaves of shrubs and low trees. When browsing foliage, this hare can stand on its hind legs and keep its balance for several minutes, eating bush leaves. If necessary, the animal pulls the branches towards itself, hooking them with its front paws.
Great Crimean hare has long mobile ears and large bulging eyes; the field of vision is almost circular, and the hearing is very keen. This animal can defend itself from an enemy by biting and kicking, but more often prefers to flee.
The wool color varies from brownish-gray to ochre-red; male and female do not differ in coloration. The tips of the ears of this hare are white with a black border from the outside. In case of danger, the animal turns its ears upright and twitches them slightly. Seeing this signal, other individuals also become alert. The underside of the tail is white; a raised tail means alarm.
Great Crimean hare prefers sparsely wooded and arid areas overgrown with tall grass and shrubs, avoids bare rocks and too steep slopes. Rivers, gorges, and mountain ranges serve as natural boundaries between its populations.
Each group of females of this species, numbering up to 10 individuals, lives in a certain territory and jointly marks its borders, leaving their droppings and urine on noticeable natural objects. Due to this behavior feature, individuals of different groups can learn news about each other by sniffing the territorial marks of their neighbors. Males do not have a permanent territory and can travel for tens of kilometers. The male signals his presence to the females by leaving his droppings next to their marks.
The rut in great Crimean hare takes place in autumn. At this time, the females’ readiness for fertilization is synchronized and they take part in mating at the same time. Usually, a herd of females goes to one male, who behaves aggressively and even attacks other animals during the rut. At this time, he utters a loud call, which sounds like a child crying. The offspring of this species are born in the spring. There are 2 large cubs in the litter, and only young females give birth to one cub. A newborn cub is able to stand on its feet within half an hour after birth, and at the age of 1 day it is able to follow its mother without efforts. The body coloration of the cub is mottled: there are dark spots of various sizes scattered on the back against a lighter background, and the head and legs are the same color as in adult animals. Occasionally, the spotted juvenile coloration persists for life. The cubs are fed by all the females living in the same territory, so the survival rate of the offspring is very high.
By autumn, young animals reach about half the weight of an adult, and then growth slows down. They are capable of reproduction at the age of about a year. Life expectancy reaches 15 to 19 years; females usually live several years longer than males.

African sungura (Paralagus zinjii)
Order: Lagomorphs (Lagomorpha)
Family: Hares (Leporidae)

Habitat: rainforests of Zinj Land.

Picture by Alexander Smyslov

Lagomorph mammals – hares, rabbits, and related pikas – form a fairly successful group of animals having a worldwide distribution, with the exception of Antarctica; it happened so due to human activity also. Despite this, lagomorphs are fairly conservative animals that have changed relatively little over many millions of years of evolution. They early mastered the ecological niche of a small cursorial herbivore, and the body and leg structure adapted to lope proved to be very successful over millions of years.
In Neocene, this situation changed somewhat: the descendants of hares evolved on Earth, that occupy the ecological niches of large herbivores – gracile fast-running harelopes, as well as their giant relatives, such as the obda and lagomoropus. African sungura is another large hare species (named after the African name of the hare).
In its appearance, this species resembles some kind of ancestral form of the harelope, but it is their rather distant relative. It is a fairly large animal, about 1 m tall at the shoulders, weighing up to 50 kg. It is covered with unicolour reddish-brown fur on the body, and lighter, fawn-colored wool on the legs, head and neck. Males are slightly larger than females. The animal’s ears resemble those of a hare – they are long and mobile, with white tips that are clearly visible in the shade of the forest.
Unlike the harelope, sungura has only two middle digits on its front legs that have hooves (in fact, these are thick, shortened claws, like in camel) and are connected together by elastic springy ligaments. The movable inner fingers have typical claws, and they are quite large. When walking, this animal bends them back so that they do not touch the ground and remain relatively sharp. However, these claws are used not as weapons, but to bend branches with foliage to the mouth of this beast. Sungura can stand on its hind legs, as does its distant relative from Azores of Neocene epoch. Hind legs are three-toed, with hoof-shaped claws and corneous pads on the feet.
Sungura feeds on various vegetative foods, mainly foliage, but it can eat bark and moss from trees, tree fungi and epiphytes, and even food of animal origin such as insects, bird eggs and chicks. Larger predatory animals often attack it, so sungura is a rather keen and cautious animal, usually active in the morning and evening, at dusk, and living in dense forests. This animal rarely appears in sparsely wooded areas and in open areas; it happens only at watering holes. Usually the animal drinks water from forest puddles and streams. Its sense of smell and hearing are good, and its eyesight is sharp.
Sungura has no pronounced mating period – in females of this species, sexual maturity comes at the age of one year, in males at one and a half years. The females leave odorous marks, the males fight for the right to mate, sometimes quite seriously, inflicting wounds with the claws of their forelegs. Unlike their hare ancestors, adult sunguras usually live in pairs and raise their offspring together. Sometimes 2-3 pairs form a small herd, but it does not happen very often. Females of this species give birth to 1-2 cubs, and they are already quite large (about 3 kg at birth) and well-developed – they can walk a few hours later, and after a few days they run along with adult animals. A female can produce offspring up to 3 times in 2 years.
Sunguras can live up to 13-15 years, but their average life expectancy is no more than 8 years.

Alpine burrower (Procaecolagus visibilis)
Order: Lagomorphs (Lagomorpha)
Family: Rabbit burrowers (Caecolagidae)

Habitats: Southern Europe, northern slopes of the Alps, mountain areas; the area of forests and alpine meadows.

Picture by Alexey Tatarinov, colorization by Biolog

Initial image by Alexey Tatarinov

Eurasia in real had never been an isolated continent. Only in early Cenozoic the midland seas had separated it into some fragments for a short time. But later water had receded, and the continent became the whole again. Connecting in various geological epoch to Africa and North America, Eurasia every time took part in exchange of flora and fauna representatives. Therefore the evolution of new endemic family of animals in Eurasia is rather rare event.
One endemic family of Eurasian mammals is rabbit burrowers family (Caecolagidae), including the descendants of rabbits specialized to burrowing habit of life. In area of steppes and forests of Europe there are some species of rabbit burrowers (Lepospalax), herbivorous mammals specialized to underground life. The species of animals close to them, a relict of early radiation of family is Alpine burrower living in the Alpes.
As against to species more evolutionally advanced, this animal has kept small eyes, hardly distinct among wool. It has very bad sight sense: Alpine burrower does not distinguish colors and is short-sighted. Lack of sight, however, is quite compensated by keen sense of smell and hearing.
The high-mountainous climate is hard; therefore Alpine burrower is larger than its plain and forest relatives and also has denser fur. It has muscled cylindric body about 55 – 60 cm long. Wool of animal is one-colour, dark brown or black at some individuals. Due to such colouring these animals are easily heated in rays of cold mountain sun.
Skull of animal is very strong; frontal and jaw bones are very thick. The forward pair of incisors is directed forward. These incisors are larger, than at plain-dwelling species; enamel layer on them is folded, that additionally strengthens their durability, and the teeth bases are stretched far back along the top part of skull. Strengthening of incisors is connected to necessity to dig tunnels in stony ground. Calvaria at Alpine burrower is wide. It carries out a role of protective helmet and can sustain significant loading – with the help of head the animal can raise and roll away stones weighting over 30 kg. Edges of calvaria overhang above eyes, protecting them from ground ingress. Nostrils of animal close at digging, and the mouth is protected from ingress of ground by lips outgrowths. Auricles of animal are short, rounded and gristly. The special outgrowth closes acoustic duct during the ground digging.
Paws of Alpine burrower are short and muscled. Forepaws are armed with strong claws, and muscles are attached to wide shoulder-blades. Tail of animal is very short.
Alpine burrower appears often enough on ground surface – at night animals eat grass and browse leaves of bushes, and in day time occasionally come out to get warm on sunny place. Similarly to their steppe relatives, Alpine burrowers drag in holes bush branches and bunches of grass dug out at the surface, in order to eat it in safety. It promotes enrichment of ground by nutrients. In addition to it Alpine burrower eats sappy underground parts of plants. It has immunity to plant poisons and can eat poisonous bulbs and tubers without any harm for itself.
Alpine burrower digs the vast systems of tunnels. The significant part of its holes is located at the depth of 20 – 30 cm, but tunnels for wintering stretch to the depth of several meters. Its building activity promotes aeration and hashing of ground, but this species can live only in places, where ground layer is thick enough for digging of tunnels. This species lives in small colonies numbering up to ten adult females and their posterity. Males have no constant territories and move from one colony to another, searching by smell for females ready to pairing.
Two times per one year female gives rise to cubs. In litter usually it is up to 5 – 6 cubs though large female in good physical shape has an opportunity to give birth to ten cubs at once and to bring them up successfully. They become sexually mature at the age of 5 – 6 months.

Beringian hutmaker (Architectona beringica)
Order: Lagomorphs (Lagomorpha)
Family: Haymakers (Ochotonidae)

Habitat: Beringia, Northern Asia, Big Kuril Isles; in New World from Alaska up to Greenland, to the south this species penetrates rather far along mountain ridges.
During Holocene epoch in “shadow” of hares there were their less appreciable relatives – haymakers (Ochotona). They are similar to rodents, and have no features of anatomy characteristic for hares – long back legs, permitting to develop high speed. But these lagomorphs have curious features of behavior – they gather plants and make of them hayricks for winter (for what they are named). In addition some species strengthen hayricks by stones and branches.
During the period of transition from Holocene to Neocene this course of evolution had been picked up and successfully advanced. Evolution successfully realized the task of survival of these small mammals in some steps. In glacial steppes of Central Asia where it is a lot of grass, climate is typically continental and winter is very cold, haymakers had became larger similarly to all polar animal. Accordingly, they began to provide a plenty of hay, and to protect it from wind at them feature of behavior was developed: animals began to throw large branches atop of hay. Surviving in steppe in small colony is rather difficult, and therefore, animals began to unite to the “towns” numbering tens of adult individuals: it helps them to increase efficiency of hay reserve.
But to prepare dry grass for winter yet does not mean to spend winter successfully. Large herbivores may easily find and to have eaten all hay provided by haymakers. And in steppes of an ice age herbivores were numerous. It were representatives of hoofed mammals, and also large rodents, new species have appeared in ice age. To save forage gathered to the winter, separate animals began to protect stocks, attacking on herbivores, and driving them away by cries, jumps and even bites. And then some populations had made one more step: they had started to use stocks of hay as shelters, gradually eating them up from edges and arranging an inhabited hole in middle of haystack. Gradually among them animals never settling in holes and other underground shelters had appeared. This step of evolution had resulted to changes of “house-building” behavior: “having come off” from dependence on available holes, rocks and crevices, animals have started to improve “architectural” behavior. They have started to build inhabited tents separately and did not mix them with stocks of forage. Inhabited tents of these animals began to be improved in features of design: at their construction a plenty of branches of trees and prickly bushes was used. For protection against enemies animals began weaving of branches dense walls, and the internal part of inhabited tent is covered with grass for warming. So the inhabited tent is completely separated from stock of forage in behavior of animal, and the building behavior evolved irrespective of food- providing one.
The Beringian hutmaker had kept features of haymakers in its appearance: it is similar to short-legged tailless marmot. Auricles of animal are very small, and eyes are large: it is an adaptation for life in conditions of polar night.
The body of Beringian hutmaker is covered with rich fur becoming longer to the winter. The fur is colored red with longitudinal black strip along the back. Wood populations of hutmakers also have dark speckles on back, and often strip is faltering. The length of body of this animal is about 40 cm; female is larger than male.
This species builds shelters as tents of branches, warmed from within with grass and bird feathers. For construction of dwelling the Beringian hutmaker chooses the prickliest branches, including coniferous trees ones. Building their shelter, animals accurately cut them out by strong incisors from the tree-trunk, and drag to building tent. To not give out their presence, animals cut branches on bushes from the edge of feeding territory. For an internal lining of house animals gather soft plants, thin stalks of grasses, wool of sheded animals, and feathers.
In tent up to 2 meters in height there are some inhabited chambers at two or three floors. The population of one tent makes approximately 4 – 5 pairs of adult animals, and their posterity. Near to inhabited tent stocks of food for winter are located: animals gather some stacks of grass, and surround an inhabited tent by them – it complicates their search by predators. Beringian hutmakers start to provide a forage approximately from second half of summer. To dry up a grass and to not spoil it during a rain, some animals in clan constantly watch weather: if there are signs of rain, they quickly carry off drying grass under trees. In summer the majority of animals are occupied with preparation of stocks of forage – they run to glades, cut the overgrown grass, and drag bunches of picked plants to the common storehouse.
In winter to keep stocks of a forage is vital for clan, therefore in winter in stacks of hutmakers adult animals and teenagers often “are on duty” – usually they are males having subordinated position in clan or young animals not having families.
The adult females already had giving rise to cubs, stand at top of hierarchy in clan. Per one year at them it may be 2 litters. Cubs are born well advanced, with opened eyes and covered with wool. They early become independent: already at week age cubs actively eat forage of adult animals. The young growth, which has been born at the end of summer, spends winter with parents, and the posterity from first packs arranges new settlements independently. They quickly grow, and can give posterity the next year. Life expectancy of Beringian hutmakers can reach 10 years.
Young animals frequently “convert” for habitation old stocks of forage, strengthening walls of stacks by branches, and arranging inside inhabited chambers. Doing it, they as though repeat evolution of dwelling of the hutmaker - from stock of forage to constant habitation. Usually young females from growing old clan do it. Gradually they move to the true specially made tents, and their posterity occupies their habitation.

Sun flying fox (Posteidolon solaris)
Order: Chiropters (Chiroptera)
Family: Megabats (Pteropodidae)

Habitat: Zinj Land, tropical woods.
When till the ecological crisis at the boundary of Holocene and Neocene some birds had become extinct, including predators and the majority of tropical groups like parrots, bats had an opportunity to occupy new habitats which were formed in Neocene. Some species of these mammals began much more active in day time, and in some cases compete to birds as equals. An example of such species of chiropters is the sun flying fox, the descendant of palm flying fox (Eidolon helvum), living at the Eastern-African subcontinent (Zinj Land). Appearing in conditions of partial isolation, this species had appreciably changed habit of life, had settled in rainforest, and had partly occupied an ecological niche of animals of forest canopy.
This is rather large chiroptere: body length is about 30 cm, and wingspan is almost 1 meter. The animal differs in rather massive and strong constitution, and weighs about 2 kgs. Wings of sun flying fox are shorter and wider, than at other representatives of order: it is directly connected with the habit of life of this animal. Sunny flying fox does not like to fly long, limiting to short flights from tree to tree. In rich tropical wood skill to fly quickly is not always expedient, but well clambering animals get appreciable advantage in survival. More often animals of this species prefer to climb on trees, clinging by hind legs and hooked claws growing on free thumb of wing. Thumb at this animal is advanced much better, than at other chiropters: it is thicker and stronger, and claw on it permits this animal to hang under the branch.
Hanging to branches upside down, the sun flying fox dexterously moves on them in searches of fruits. By manner of movement it resembles the sloth, but moves much faster than it (this chiroptere accelerates speed up to 5 km per hour). When it is necessary, animal can even make small jumps from branch to branch like a monkey. This animal reluctantly flies, making it only in case of emergency – flying to other tree in searches of food, or escaping from clambering predators. In flight sun flying fox feels like not so confidently, as other species of chiropters: it frequently flaps wings (its flight resembles flight of gallinaceous birds), and sometimes at all prefers to glide from tree to tree similarly to flying squirrel. The importance of flight in life of this species is so low, than even the animal having injured flying membrane, can exist and take part in breeding normally.
The color of wool at sun flying fox partly justifies its name: fur is darkly yellow (“honey” shade) or sometimes light brown. On stomach wool is brighter, than on back. Membranes of wings are covered with thin wool on the top side. On neck of animal there is an ornament: collar of rusty-red fur, especially advanced at males. Skin of wings is dark brown, contrasting with color of fur.
The head of the solar flying fox looks similar to head of dog with small ears and large reddish eyes. It is 0rather wide, because animal eats various vegetative foods and at it chewing muscles are advanced. On skull of this chiropters even the low longitudinal crest serving for their attachment is developed. This chiroptere usually eats fruits of any degree of ripening; from unripe up to began to rot, but it also supplements a diet with leaves and young sprouts. Sometimes sun flying fox includes food of animal origin to its diet: eggs and nestlings of birds, frogs and insects. Animal eats fruits simply hanging on branch near to them, and catches small animals by tenacious hinder legs. Their flexibility permits to this chiroptere to bring the caught prey by hinder leg right to the mouth.
As against flying foxes of other species, this species keeps solitarly. Sometimes on one fructifying tree it is possible to meet several animals of this species, but they keep separately, not coming nearer to each other. In morning time animals of this species like to “sunbathe”: climbing up on light up branches, they stretch wings, having put their inner side and stomach to beams of rising sun.
The breeding season takes place till all year. Males ready to pairing, involve females by special “warbles” sounding like long series of clicks. To meet the female the male prepares special branch: on thick horizontal branch he makes some odorous marks, using musk secretions of specific gland on chin. The same secretions impregnate his fur collar, strengthening the smell of animal. Female ready to pairing, finds these marks in forest canopy, and waits for the male near of one of them. To draw his attention, the female utters short calls. After pairing female leaves male’s territory and he continues marriage appeals.
Once per one year at the female one cub is born, occasionally there are twins. The female holds posterity in the “cradle” formed by stomach and wings. First some days of life the cub is so helpless, that the female, compelled to fly, carries him in mouth. Later the cub becomes covered with wool and begins able to keep by mother during her flight. Approximately at three-week age cub starts to study to climb on branches. Posterity stays with mother for a long time: even having studied to fly, and having reached 70 % of weight of adult animal, the young animal does not leave mother. Because of these circumstances the rate of reproduction at sun flying foxes is very slow: for one year the female can give birth to posterity only once (or two times if the first birth happens in the beginning of current year and the second one happens at the end of year). But the posterity is teaching by mother in skills of food searching in tropical wood, learns terms of fructification of various trees and ways of protection against enemies. Besides the female actively protects posterity in first months of life, and its survival rate is rather high.

Crested flying fox, hoatzin bat (Xenopteropus hoatzinoides)
Order: Chiropterans (Chiroptera)
Family: Flying foxes (Pteropodidae)

Habitat: islands of Eonesia, tropical forests.
The islands of Eonesia appeared above the surface of the Pacific Ocean after the human disappearance, so the flora and fauna of these islands formed exclusively in a natural way. As a result, many groups of animals characteristic of the continents are missing from the fauna of the archipelago, and their place is occupied by descendants of species that have managed to colonize the islands. On the large and rather humid islands of the archipelago, the place of the herbivorous inhabitant of tree crowns is occupied by a large representative of flying foxes, crested flying fox, which is named as hoatzin bat for its gastronomic preferences and lifestyle. This chiropteran species switched from feeding on fruits to feeding on leaves, which allowed it to greatly expand its fodder base and greatly increase in size: the weight of an adult reaches 2 kg with a wingspan of up to 180 cm.
The crested flying fox’s head is shortened and expanded: the muzzle is more similar to that of a lemur, except for the location of the ears. The skull is slightly elongated vertically, and there is a sagittal crest on the crown, to which strong masticatory muscles attach. This crest is well-visible on the beast’s head because it is decorated with a narrow strip of stiff erect wool. Crested flying fox has large eyes and a short muzzle with wide nostrils that facilitate breathing under intense activity. The ears are short, wide, pointed and very mobile. The fur of these animals is colored gray with a darker area on the back, the hair crest on the male’s head is lighter, and the fur forms a dark “mask” around the eyes. Individual variations of the background color from light gray to reddish are possible. Areas covered with short hair are also located on the upper side of the wing membrane. The male and female do not differ in wool color.
The specifics of the diet have left their mark on the structure of the teeth of this species. The teeth are tubercular, wide, and the canines are very short. This flying fox species is capable of chewing food with lateral movements of its jaws. Crested flying fox feeds on the foliage of trees, obviously preferring the young foliage at the tops of the shoots. It has not lost its ability to fly, but it flies reluctantly, preferring to hang from branches upside down. Pulling a branch towards the mouth with its thumb, it tears off the leaves with its lips and sometimes bites off the tips of the shoots. Mushrooms and fruits of plants are an addition to its diet. The animal has a long intestine and hangs for a long time under the branches, having hooked on four limbs and digesting its food. The specific diet has left its mark on the animal’s lifestyle, making it not moblie. Unlike other leaf-eating animals, coprophagia is not characteristic for crested flying fox.
This species lives in groups of 10 to 15 individuals and is polygamous: males own a harem of 3-4 breeding females. Crested flying foxes have developed sound communication – the animals produce a series of low-frequency clicks, as well as a variety of sounds: squeal, meowing and single harsh shouts. Dominant males drive rivals away from their females with loud screams, preferring not to engage in a fight in which their wing membranes can be damaged. Driven out by a stronger rival, the male can take over another harem or assemble its own, “luring” the females from other families. Older males tend to lead a solitary life. They prefer not to fly, and only climb trees.
The wings of these megabats are wide and relatively short. The thumb of wing is very powerful, equipped with a large claw, and can hold the weight of an adult animal. Crested flying foxes usually use flight only to move to new feeding grounds within their territory. They can also migrate between islands, but very rarely; this is usually done by young males who do not possess their own harems. Their movements from one island to another maintain the unity of the population.
Once a year, the female gives birth to one cub. While it is small, the female carries it on her body. The grown-up cub stays on the tree, and the female feeds it with a semi-digested pulp of leaves: in this way she gives it symbiotic microflora that helps to digest the cellulose of the forage. The female actively communicates with its cub with the help of sounds, and easily recognizes its voice among the voices of other members of the colony. At the age of 4 months, the young individual already becomes independent and begins to feed on leaves and fruits, although it still is a bad flier. At this time, the cub usually follows its mother and tries to fly, when hanging down from the branch on its hind legs and flapping its wings intensively. Puberty occurs at the age of 1 year, and life expectancy is up to 20 years.

Chinese or Short-faced flying fox (Pteropus brachyops)
Order: Chiropterans (Chiroptera)
Family: Flying foxes (Pteropodidae)

Habitat: central and eastern China, Asia south of the Himalayas.
The chiropteran order is divided into two unequal groups: the bats themselves (microbats) and the flying foxes (megabats). The latter differ from the former in their large size, shorter tail, lack of outgrowths on the muzzle and exclusively vegetarian diet: unlike most microbats, megabats feed on vegetative foods such as fruits, which they search for with the help of vision, so their ability to echolocation is less developed, and their eyesight is better than that of their small relatives.
Also, the lifestyle limits the range of this chiropteran family to the tropics. The decrease of forest areas and the destruction of ecosystems by humans caused a decrease in the number and extinction of a number of flying fox species, but the warming in Early Neocene and the expansion of habitats suitable for their life allowed flying foxes to restore their numbers and evolve new species.
The Chinese flying fox is one of the northernmost species of megabats, a species with a wide range. It is a very large chiropteran, reaching about half a meter in length, with a wingspan of about 190 cm, weighing about 2 kg. Like all flying foxes, this animal is herbivorous, but it feeds not only on fruits, but also on nuts and various seeds, which it easily cracks: its jaws are stronger and shorter than those of other species, with strong tubercular teeth.
The Chinese flying fox is covered with rather thick dark brown or even black fur; sometimes there are individuals with lighter spots on a dark background. The wing membrane is of the same color, sometimes being slightly lighter than the body. Male has a peculiar “beard” of elongated hair growing on its chest, which indicates the level of testosterone in the blood. The ears are relatively short, and the eyes and nostrils are large and wide: this animal has well-developed eyesight and sense of smell, but the ability to echolocate is actually absent.
Like other flying foxes, the Chinese flying fox is a diurnal mammal. It wakes up early in the morning and starts searching for food. This animal is a good flier, but in search of food it is also able to climb trees and branches; the weight of the animal does not allow it to climb the thinnest branches, but its long paws, especially the front ones, and the claws of its thumbs compensate for this – using the claw of its thumb, the Chinese flying fox can pluck fruits and bring them to the mouth. The musculature of this megabat is well developed; it is a fairly strong animal of graceful build, and in the dexterity of climbing branches it is not inferior to small primates such as lorisids. It can even cling to a branch with only its hind legs, and pluck fruits with the claws of its wings.
This chiropteran makes seasonal migrations. The mating season of this flying fox begins in autumn, when these animals begin migrating south, especially in the northern part of their range. Shortly before the start of the migration, they gather in small flocks consisting of animals of both sexes, and the females show their readiness to reproduce by emitting a specific smell. Competing for females, males push each other away from the chosen female, while hissing loudly and opening their mouths.
In winter, while Chinese flying foxes live in warmer countries, their females give birth to cubs. The females feed them with milk and carry them on their bodies. At the end of the mating season, males of this species gather in their own flocks and keep apart, not caring about their offspring. Getting good nutrition, the cubs grow quickly and can lead a completely independent life by spring, but they still stay in one flock with their mothers: they return to the north together, and only there do the young animals pass to independent life. The return to the north takes place in late spring, when early fruits begin to ripen in the north of the species range. Puberty occurs at the age of 1 year.
The enemies of the Chinese flying fox are mainly birds of prey, which attack these bats when they migrate north and south, and in the tropics, where these animals winter, there are also large arboreal pythons, but most of these animals die during migrations.
Chinese flying foxes can live for about 25-30 years.

Yellow Browed Brush-tongued Bat (Florapteropus australis)
Order: Bats (Chiroptera)
Family: Megabats (Pteropodidae)

Habitat: The north of Meganesia, tropical rainforest.
Bats are among the most numerous of mammals in the age of man, one would expect their success in later epochs, and so it goes in the Neocene. Bats reached Australia early in the age of mammals, by being able to fly, and they still prosper there. From the common Australian Flying Fox (genus Pteropus), descends a genus of bats which feed entirely on the nectar of forest trees, avoiding competition with birds by feeding at night. Previously during the Holocene, similar animals had appeared, but were the victims of the anthropogenic extinctions caused by forest clearing.
Nominal example is the Yellow Browed Brush-tongued Bat of the tropical north of the continent, smaller than its large ancestors, with a wingspan of only 40cm and a weight of 80 grams. These bats typically rest by day in small groups scattered throughout the forest, taking wing at night to forage in the treetops upon various flowering trees, night blooming flowers and those that do not close at night are preferred, though they will rob nectar from day flowers which have closed.
The animal has a relatively narrow snout which is more acute than its ancestor, but this is obscured by a brush of whiskers which is conducive to the spreading of pollen from flower to flower, these bats importantly pollinate many kinds of night blooming flower. The tongue of this bat is slender and covered in a prominent brush of hair-like papillae which it uses to extract nectar from flowers. Fur is colored fawn grey with a saddle of chocolate colour across the shoulders, and the top of its head is a golden yellow. Wings are relatively broad but not as big proportionately as those of typical fruit bats such as its ancestor. The call of this bat is a high-pitched braying screech.
Breeding season occurs during the wet season when there is a flush of growth, though in a good year there may be two mating seasons. It is at this time that they accumulate in large colonies segregated by sex, bachelor groups of males compete to woo females out of a large selection. Females will choose a male to mate with based partly on his vigour and loudness, but also by a gift of regurgitated food. A single pup is born but occasionally there may be twins, gestation is about 155 days or slightly longer. Pups become independent from their mothers after about 8 months. Lifespan is up to 14 years.
A close relative is the Ginger-Headed Brush-tongued Bat (Florapteropus major), which is found in temperate and subtropical woodlands in the southeast of the continent. This bat specializes in feeding upon the nectar of proteas and eucalypts, which generally have flowers which do not close at night, and which drip nectar profusely. This form is slightly larger and more pugnacious than the nominal form, as well as having fur of a darker grey; the color on top of the head is a ginger orange. Breeding season varies in this form to reflect the seasonal climate, the main breeding season is in early spring but a second season may occur in late summer.

This species of mammals was discovered by Timothy Donald Morris, Adelaide, Australia.

Painted Fruit Bat (Toxicopterus splendens)
Order: Bats (Chiroptera)
Family: Megabats (Pteropodidae)

Habitat: The north of Meganesia, tropical rainforest.

Picture by Sauron

Having poisonous flesh in order to repel predators is usually the domain of fish, amphibians and invertebrates, and also some rare birds, but in the Neocene, some kinds of mammals evolved the ability of accumulation of poisons from their food in their flesh.
Painted Fruit Bat is descended from smaller members of the genus Pteropus, and like those, it feeds entirely on fruit, this particular bat only feeds from a few distinct types of trees, which have exceedingly poisonous fruit. This is related to its method of defence and survival, its flesh is extremely poisonous, any animal consuming it will quickly get extremely ill and possibly even die, so predators quickly learn to avoid it. Thanks to the nature of its defence mechanism, this solitary fruit bat feeds by day.
Coloration is directly related to method of defence, fur is boldly striped in black and white longitudinal stripes, almost recalling a skunk (but fur is shorter), and the skin of wings is bright orange, blotched between the fingers with black patches. Face has a “mask” of white fur on a black background, bare snout, feet and hands are dark orange. Wingspan is a meter or less and weight is up to 600 grams. Apart from coloration, this bat greatly resembles its ancestor in shape and appearance. Call is high pitched yapping or yarring, when confronted with a predator it may spread its wings and produce a loud call of a high strident pitch as a warning.
Breeding occurs during the wet season, and in a good year it may experience more than one breeding event. This is when both males and females gather in large groups in order to court. Males display their colourful wings and produce loud calls in order to impress the females, and may perform acrobatic display flights. Mates are chosen based on vigour and loudness, but also upon gifts of regurgitated food. A single baby is born, but rarely twins, gestation is up to 160 days, and the young become independent at 8 months. Initially, young are an all over reddish brown with opaque wings, and it is only as they reach adulthood, and feed profusely on poisonous fruit, that they gain their warning colours. Lifespan may be up to twenty years, somewhat longer than its relatives.

Striped singing bat (Musicilio striata)
Order: Chiropters (Chiroptera)
Family: Common bats (Vespertilionidae)

Habitat: subtropics of Europe, southwestern coast of Fourseas.
Chiropters had evolved at the Earth right at the beginning of Cenozoic, appreciably later, rather than birds. Probably, the nocturnal habit of life had helped these animals to avoid a competition to birds. Chiropters had achieved significant success in evolution - in human epoch they made up about a quarter of variety of mammalian species. Among them the species occupying various ecological niches had evolved: herbivores, nectarivores, insectivores, predators and even blood-sucking parasites. Chiropters of some species form colonies which number is measured by millions of individuals.
Chiropters had rather safely gone through global ecological crisis. Among them highly specialized tropical species, and some species of small total number had become extinct. But right after stabilization of environment conditions chiropters had entered new blossoming. Some Neocene chiropters during the process of evolution had developed very original features of behaviour.
Some kinds of separate genus of chiropters – singing bats (Musicilio) live in warm-temperate and subtropical areas of Europe. They belong to the number of medium-sized representatives of group – wingspan at them does not exceed 30 cm, and more often it is even smaller.
These animals have not only echolocation, but also well advanced system of sound communications. Voices of males of these mammal differ in originality. At different species of these chiropters at similar sounding echolocating signals voices in heard part of sound range strongly differ. These animals are able to utter various sounds – from single clicks and simple monotonous trills up to rather complex signals, including a sequence of sounds of varying frequency.
Striped singing bat lives in subtropical forests of Europe. It is one of typical representatives of genus. At these animals wool is colored black, and on this background from shoulders along the back two wide white strips stretch. Hairless membrane of wings is also dark. Male and female at this species differ in colouring. At males strips on back are wider, than at females, and on throat often there is a white spot. The female of striped singing bat has two thin faltering strips on back, and besides it is larger a little, rather than male. It is the most impressively looking species of the genus, other species are colored less brigher.
Muzzle at all singing bats is short and wide. On the nose high leaf-shaped outgrowth grows, on each side of which chink-like nostrils extended vertically open. Mobile edges of nostrils are supplied with special muscles which change width of nostril and density of its closing. “Playing” by edges of nostrils, singing bats “sing” at the exhalation. They send echolocating signals by mouth, as usual bats.
At singing bats there are large oval ears with pointed tips and large hircuses. At striped singing bat edges of ears are covered from external side with short white fringe.
Wings of these chiropters are short and have rounded tips. Long tail is half included in interfemoral membrane. Flight of these chiropters is slow and flitting. Singing bats are active in twilight and at night. They are mainly omnivorous, and also eat large flying insects (moths and beetles) and ripe fruits of plants. Various species have preferences in diet, but the species eating more vegetative food dominate at the south, and at the north migrating insectivorous species prevail. But even northern species during the fruit ripening time pass to partly vegetarian diet.
The courtship season at singing bats comes in summer, and one cub is born at the female in spring of the next year. At each species of singing bats the specific song differs from those at close species. Males of striped singing bat involve females with the sounds similar to twittering. Every male displays itself, hanging on the branch from below and arranging the “concert”. Sometimes on one tree some males gather, and they organize the original musical competition. However, at these animals males not always suffer the presence of competitors – it happens, strong, but badly singing male simply disperses contenders to near trees. But it has very insignificant chances of success – during fight it is compelled to interrupt song, and females search for others males. Every male tries to sing as long, as it is possible, not interrupting. Calling the female, male utters short abrupt trills. When the female answers his appeal, male starts to sing actually courtship song – series of whistling sounds. First “syllable” of his songs is the longest, and each subsequent one is shorter, than previous, and its tone is higher. During the song performance male stretches wings and displays to the female its own size.
In the afternoon singing bats prefer to hide in shelters – usually in hollows of trees or under bark. They do not form big colonies, and search for society of congeners only during migrations or in courtship season. Striped singing bat belongs to migrating species, and in autumn, with approach of time of cold fogs going from Fourseas, it flies to the south – to mountain valleys of Asia Minor. These chiropters make flights at night, and hide in various casual shelters, gathering in groups of some tens individuals in day time. The disturbed animals are very aggressive. They hiss to the enemy and put painful bites.
Some birds may be enemies of singing bats. During night hunting owls attack them, and large gospodar woodpecker pecks hollows where these animals hide, and eats them.
Along the coast of Fourseas, in subtropical areas of Europe with soft climate other species of singing bats are found:
Common singing bat (Musicilio cantans) is the most widespread species of genus. It lives at the extensive territory: from woods in Central Europe at the west up to forest areas in deltas of rivers flowing to Fourseas at the east. Populations from edges of area make migrations, and inhabitants of southern areas – Caucasian Peninsula and Balkan – are settled and run to short-term hibernation. This species of chiropters has dim colouring: male is black with brownish shade and white spot on throat; female has dark brown wool, and it does not have spot on throat. The only ornament in colouring of this species is thin strip of white wool at edges of ears. Ears are rounded; nasal outgrowth is wide and short. Wingspan makes about 25 cm. The voice of male represents a simple trill of short abrupt sounds.
Greater singing bat (Musicilio grandis) is the largest species of the genus – at some individuals wingspan exceeds 35 cm, though usually it is less. Colouring of wool at this species is very light – white with yellowish shade; on head there is darker “cap” (at the male it is bright red, at the female brown). This species lives at the south – in mountain forests of Balkan and Asia Minor, near borders of salt and hot Mediterranean Lowland. The basis of ration of this animal is made of fruits of trees and large insects. Courtship call of the male sounds like sharp abrupt serialized singing.
Caucasian singing bat (Musicilio caucasica) inhabits mountain and coastal forests of Caucasian Peninsula, and migrates for wintering to mountain valleys of Asia Minor. This small species of bats (no more than 20 cm in wingspan) utters the melodious modulating singing similar a few to the voice of small songbirds. This species of chiropters is especially active in twilight and in dawn time. The wool is colored grey with dark strip along the back; at males on throat there is a yellowish spot. This species eats insects, and only in middle of summer passes to feeding on soft and overripe fruits.

Shy bat (Capuccionops cryptus)
Order: Chiropterans (Chiroptera)
Family: Vespertilionid bats (Vespertillionidae)

Habitat: forests of Southeast Asia, Jakarta Coast.
In Neocene, as in the human epoch, chiropterans represent the second most diverse group of mammals after rodents. The reduction of the area of tropical forests during the human era and during the Ice Age at the turn of Holocene and Neocene led to a certain decrease in the species diversity of the order, but later the rapid speciation of bats in the expanding tropical forests of Early Neocene compensated for this damage. Among the Neocene bats, species have evolved that have developed new strategies in the struggle for existence. Shy bat, which lives in the Asian tropics, has developed an interesting strategy for self-protection from predators – its survival is ensured by skillful camouflage, like its neighbors, the nightjars.
This bat is a solitary insect-eating form of small size. The length of an adult is about 10 cm, and the wingspan is up to 25 cm. Wings are wide and rounded, providing a maneuverable flight among the tree branches. Nose and lower jaw lack skin outgrowths, only a small skin fringe stretches along the outer edge of the nostrils, which helps focus the sound beam during echolocation. Ears are wide and pointed, with their lower edge extending forward to the animal’s cheek. They are covered with thick velvety fur on the outside. The animal’s eyes are small but well-functioning. Teeth are pointed, of insect-eater’s type, equipped with cutting edges.
The coloration of the upper side of the animal’s body is gray with an olive tinge, with numerous black specks forming a pattern vaguely resembling the texture of tree bark. The outer surface of the ears is colored in a similar way. At the edges of the body, above the wing membrane, the hair is slightly elongated and forms a kind of fringe that masks the folded wing membrane. The underside of the body is gray and lacks spots.
This animal spends the day on tree trunks, among thickets of epiphytes. The wool color on the bat’s back allows it to remain unnoticed by birds, which, moreover, rarely leave the forest canopy and appear on tree trunks. The animal’s ears provide additional camouflage: at rest, they fold forward and cover its head like a hood. Thus, the bat artfully disguises itself as an outgrowth on the tree bark, while remaining motionless. Unlike other bats, this species is able to stay on the substrate not only head down, but also head up – in this case, the animal clings to the bark with its thumbs. Usually, the resting place of this bat is located near thickets of epiphytes or under the stem of a liana twining along the tree trunk.
This species forages in the forest canopy and prefers not to descend into the lower canopy and undergrowth. The main prey includes moths, less often large mosquitoes. This bat swallows small prey on the fly, and tears apart large prey while clinging on a tree trunk.
Twice a year, the female gives birth to one cub. While it is little, she flies hunting with it, and the grown-up cub is left in a shelter – usually in a hollow on the tree trunk, or among the mushrooms growing on the trunk. At the age of 2 months, the young animal becomes completely independent. Puberty occurs at the age of 8 months. Life expectancy is up to 15 years.

The idea of the existence of this mammal species was expressed by Tim Morris, Adelaide, Australia.

Mediterranean or salineland serotine (Eptesicus halophilus)
Order: Chiropterans (Chiroptera)
Family: Vespertilionid bats (Vespertillionidae)

Habitat: maquis and mountains of the Mediterranean lowland.
Chiropterans have lost their largest species due to human fault. Some small chiropterans became extinct due to habitat destruction and the undermining of the food supply. In Neocene, the survived species have restored species diversity comparable to that which existed before the age of man. One of the species, the serotine bat (Eptesicus serotinus), lived, in particular, on the islands of the Mediterranean Sea. It was here and in maquis that a complex of semispecies evolved, which named collectively as a salineland serotine.
It is a small bat: body length – 5 cm, tail length – 3 cm, wingspan – 25 cm, body weight – about 10 g. Wool color is light brown, and variations to fawn and almost white are possible in various geographical populations. There are no outgrowths on the nose, and the wide nostrils are directed forward and to the sides. The muzzle is shortened, slightly swollen on the sides between the eyes and nostrils. In maquis, salineland serotine is active at night, and in the insular oases of the Mediterranean lowland – at dusk, when it is not hot, but the insects have not lost activity in the night chill. Frequency of echolocation signals varies from 25 to 50 kHz. The flight is fast, with frequent wing flapping, sharp rushes and hairpin turns. Animals can drink water from the surface of puddles and other temporary reservoirs, flying over the surface. During the dry season, the animal receives a significant portion of its water from its prey.
The salineland serotine spends the day in rock crevices, tree trunk hollows with narrow entrances and caves. Its main food in maquis is bloodsucking insects that fly around herds of mammals and large birds, and in the mountain oases of the Mediterranean basin – any small flying insects that it can catch. Flocks of these bats often hover around groups of resident and migratory one-toed ostriches. Separate small populations and solitary “vagrants” are found in the vicinity of hypergaline marshes, feeding near crested flamingos. Individuals from such small groups move from time to time between the mountain ranges and the maquis, maintaining the unity of the species. However, individuals from the western and eastern margins of the range have already been able to develop genetic incompatibility, although they freely interbreed with neighboring intermediate populations.
The mating season begins at the end of winter. Males fight for a female, producing ultrasonic “screams” and chasing each other. In roosting places, rival males try to push each other away from the female. A pair of cubs is born during the spring rains, when there is enough food and moisture in the habitat. At the age of 2 weeks, young animals begin to taste adult food, and at 7 weeks they become completely independent. Puberty comes at the age of 1 year; life expectancy is up to 15 years.

Ialtog (Paranyctalis ialtog)
Order: Chiropterans (Chiroptera)
Family: Vespertilionid bats (Vespertillionidae)

Habitat: littoral marshes of Europe, wintering in North Africa.
The littoral marshes in western Europe represent a strange world inhabited by aquatic fugitives from the land and land-dwelling fugitives from the sea. One of the species whose ancestors were land-dwelling is ialtog, a descendant of the common noctule (Nyctalus noctula), an original near-aquatic bat.
Ialtog is a large bat: its body length reaches 10-11 cm, and its wingspan is about 40 cm. Such a large size is associated with living in a cool climate. The length of the tail is 4-4.5cm; it is fully incorporated into the wing membrane. Ialtog has a rather stocky streamlined body and rounded wings with a thick membrane. The muzzle is pointed, lacks outgrowths, and the bat’s ears are small. Unlike many chiropteran species, ialtog has excellent eyesight. Wool coloration is bicolor: reddish-brown back and head, white throat and belly; limbs, ears and wing membrane are brown.
This bat spends its summers in the littoral marshes of Northern Europe (the name means “bat” in Irish). Ialtogs live in groups of up to 30 individuals, usually hiding in rotted from inside tree trunks or other shelters during the day. The social lifestyle helps to notice predators in time and escape from them. Activity is twilight, and animals sleep for a while in the middle of the night.
The diet of this species is diverse, and there are several basic hunting methods. Ialtog can fly above the water and catch insects, like most bats, crawl through vegetation and on sand in search of small near-water animals, and even dive from the air onto fish that appeared at the surface of the water and grab it with its teeth. Due to its dense wing membrane, this bat can even swim on the surface of the water if it accidentally falls into the water – however, usually the animal swims to a reed or tree trunk, gets out of the water and takes flight.
The food of this species includes insects, crustaceans (crabs, shrimps and scuds), worms, mollusks, fish, and sometimes small birds – usually during the migration in late summer or late spring. Ialtogs themselves are mainly caught by birds of prey and predatory fishes.
These animals winter in North Africa at the banks of local rivers, in the Saharan Nile basin or at the coast of the Atlantic Ocean, where they lead about the same lifestyle.
Mating takes place during the winter; during the migration to the littoral marshes, the pair breaks up and the female takes care of its cub alone. After the return to homeland, one cub is born, which grows intensively and grows fur very soon. Until the cub has grown large enough, the female carries it on her body, and avoids feeding near the water at this time. After 3 weeks, the cub grows big enough and is already trying to fly by itself. At this time, inexperienced young individuals often fall in water. At the age of 8 weeks, a young animal can fly as well as an adult. Puberty occurs at the age of 2 years, life expectancy is up to 20 years.

This mammal species was discovered by Mamont, the forum member.

Aotearoan Long-eared Bat (Novonyctophilus macrotis)
Order: Chiropters (Chiroptera)
Family: Common bats (Vespertilionidae)

Habitat: New Zealand, both forested areas and open country, sheltering in caves.
A natural vagrant migration of animals from both Australia and the South Pacific to New Zealand has regularly occurred in the Holocene. Native bat species there were badly endangered and subsequently became extinct, but were soon replaced by Vesper Bats that had migrated from Australia. One such species is Aotearoan Long-eared Bat, which has changed relatively little from its Australian ancestor.
This species is of mid size for a micro-bat, weighing as much as 12 grams with a wingspan of up to 30 centimetres. It generally resembles its ancestor, body fur is of dark colour and wings are pinkish grey and translucent, ears are long and very prominent. Animal is an insectivore, feeding on flying insects of various sorts but also plucking spiders from their webs, echolocation is high-pitch and faint, but effective. This bat differs from its immediate ancestors in that it roosts colonially, as opposed to singly in tree hollows and ledges, as its ancestors did. This may be a strategy to adapt to the cooler conditions present in some parts of New Zealand.
Breeding season runs from March to May, but most mating occurs around April. Females retain sperm over the winter months and ovulating and conceiving in August and September, young are born by November, when it is warm. Females give birth to twins, which remain clinging to the mother, apart from when she departs to feed at night, she finds them again by the sound of their call. Babies are able to fly within 3 months and weaning occurs 2 months later. This species forms large colonies in the mouths of glacially formed caves which are common in New Zealand; a single colony may number up to a thousand or more individuals. Large amounts of guano are produced which form the basis of a biota of scavengers and predators. Commonly preyed upon by owls, as well as occasionally mammalian predators such as wildcats or species of carnivorous bat, reptilian predators may include large Mouse-eating Gecko, which may venture into their caves. Lifespan may be up to 20 years but usually shorter.

This mammal species was discovered by Timothy Donald Morris, Adelaide, Australia.

Cat-headed pipistrelle (Hirtofalco felinocephalus)
Order: Chiropters (Chiroptera)
Family: Predatory bats (Carnonycteridae)

Habitat: tropical woods of Central Africa.

After extinction of majority of predatory birds species representatives of other groups of vertebrates began to develop their ecological niche. Usually various birds became flying carnivorous creatures, but some species of mammals from chiropters order successfully competed to them. Some bats passed from insects to more sizeable forage: they began to hunt birds and small mammals.
Cat-headed pipistrelle is predatory day time species of chiropters, descendant of one of African pipistrelle (Pipistrellus) species. Because of injurious habit of life at this animal the structure of body has considerably changed. Cat-headed pipistrelle had turned to day time predator, and now it hunts birds and small animals in trees crones finding them with the help of sight. At this species eyes are very large and directed forward: sight is binocular. Ears are long, triangular and peaked. The skull of cat-headed pipistrelle is short, jaws are rather wide: its head is similar to comical portrait of cat. The mouth of animal can open widely – it is connected to mode of catch killing: this chiroptere kills caught animals by sting in head. Its molars because of it have got the special form: they are prolonged and work as edges of scissors crushing backbone and skull of catch (the similar adaptation was at fossil “marsupial lion” Tylacoleo). Outgrowths on nose characteristic for the majority of bats at this species are small and echolocating abilities are reduced – catch can hear voice of bat and hide. This animal weighs about 300 grammes having wingspan up to 70 cm. Colouring of wool is reddish-brown, ears are black and above eyes there are black stains. On chest of male there is yellowish spot.
This species of chiropters hunt in forest among branches, therefore its flight differs in maneuverability and high speed. Wings are long but rather wide: bat easily can change direction of movement and fly round branches. Back extremities of animal are almost free: the flying membrane is attached only to external edge of hips; short tail has only small skin edging on its basis. Hinder legs at this bat are very tenacious, the toe and little toe can oppose to others, why the grip of this animal becomes doubly stronger. On toes hooked claws grow. Speed of reaction at cat-headed pipistrelle is so fast that this mammal can easily grip birds by each paw promptly having flown by through their flight.
Mammal eats caught prey somewhere on branch. Pipistrelle plucks caught birds by hinder leg holding in mouth (on the contrary it flays small mammals by teeth holding in paw). The animal eats catch with bones easily chews them by powerful jaws.
Each pipistrelle has hunting area in forest canopy vigilantly protecting from neighbours. When two pipistrelles meet at the border of territories, they begin menacing demonstrations which however do not pass to combat: animals are afraid to injure flying membrane, therefore teeth and claws are out of use. Animals open wings, flap by them to the contender’s side and loudly squeal at this moment, widely opening mouth and showing canines. After this bloodless, but noisy duel both animals mark borders of territory by urine and peacefully miss each other.
Twice per year in breeding season males “paste up” on borders of territory odorous “announcements” for females with the help of secretions of musk glands on throat. Female ready to pairing hangs to branch near to such mark and waits when male begins to inspect borders of its possession. Sometimes it even rubs stomach against male’s mark to interrupt its own smell and to not cause aggression in it. If the male is to her liking female forms pair with him and moves on his territory. Pairs at cat-headed pipistrelles are formed not only for breeding season, but also for all time while female look after posterity – two and sometimes even three cubs. At this time male is compelled to hunt almost constantly. Cubs are born naked and blind, but quickly open eyes and become wooly. First time female carries them on itself but later starts to leave them on branch. Approximately since the second week of life cubs gradually pass from milk to meat food – in the beginning they eat semidigested meat, then fresh one and at last at bi-monthly age they study to catch small animals independently.
Sexual maturity comes at the age of half-year. Life expectancy is about 10 years.

Silent flying wolf (Pterolupus silentiosus)
Order: Chiropters (Chiroptera)
Family: False vampires (Megadermatidae)

Habitat: light forests at the south of Meganesia.

Picture by Lambert

After mass extinction evolution can make unexpected moves and then in ecosystems very original species of live creatures evolve, occupying in ecosystems a role unusual from the point of view of the human. It has taken place so in Neocene Meganesia (the continent uniting Australia and New Guinea). Here predatory medium-sized birds were pressed by very unusual representative of chiropters which has received the name the flying wolf.
In Holocene in tropics of Old World large chiropters, flying foxes, had widely settled. They had received the name only for features of shape, because they were vegetarians. The flying wolf from Meganesia bears the name more deservedly. Its appearance does not resemble wolf’s one at all, but this chiropteran has surpassed its ground wingless “prototype” in injurious bents and dexterity of prey catching. Flying wolf belongs to suborder Microchiroptera and is the largest species of bats of Neocene. Wingspan of this animal is about 150 cm, and weight reaches 1 kg. Body of this animal is muscled, on chest the keel (atypical formation for small chiropters, which is more typical for large flying foxes) is well advanced. Wings of flying wolf are long and pointed, and flight is very fast and maneuverable. The thumb on wing is well advanced and mobile; with its help flying wolf holds catch when eats it, and also clings to bark of trees and rocks. The wing membrane of this large species of chiropters in addition is strengthened by collagen fibers which stretch from bones to edge of wing.
The tail of flying wolf is approximately equal by length to back extremities. The interthign membrane completely includes it, but covers back legs approximately up to knee joint. The membrane of wings also covers legs only up to knees. Shins of this animal are lengthened and muscled, well adapted for catch seizing. Toes are mobile and armed with hooked claws from which the small animal cannot escape. On little toe the especially large claw, with which help the animal kills the seized animals, is advanced.
The wool of animal is colored brown, on throat there is a spot of yellow wool. Eyes are led round by rings of white wool. Membranes of wings are colored dark grey.
Flying wolf hunts in day time and in twilight, and has good color sight. Echolocating abilities at this chiropteran are substantially lost (this animal does not distinguish small objects), and express only during the flight in twilight. During day time hunting flying wolf does not use an echolocation at all (hence its specific name). In connection with this feature the muzzle of flying wolf is partly lack of skinny outgrowths characteristic for bats. On nose bridge of this animal the short vertical outgrowth grows, and small skinny platen surrounds nostrils from outside. Ears are rather short and triangular-shaped with pointed tips. They are connected to each other in the top part of head, and their tips are turned in sides.
This species of bats is an active predator, and eats various vertebrates of small and medium sizes. More often it hunts birds and small ground or climbing animals – mammals and reptiles. Large eyes of this predator are shifted forward and provide good binocular sight.
During the hunting flying wolf grasps catch by hinder legs, and sticks claws deeply into it. The sharp claw on little toe puts to catch deep wounds from which it bleeds profusely and perishes. Flying wolf especially frequently attacks various birds – pigeons, small parrots and large passerine birds. The predator hunts them not hiding: it frightens away birds, and rushes through their flight, trying to grasp catch by paws. Sometimes it succeeds to seize two birds at once. This chiropteran attacks small animals from air, and tries to kill by claws at once. Flying wolf does not like to hunt among rich trees where the probability to injure the wing membrane is high. However it dexterously seizes various tree-climbing animals from large branches and tree trunk.
The courtship season at flying wolf comes at the end of rain season. At these aggressive bats each individual protects the territory from neighbours, and because of it pairing can become complicated. The male is larger than the female, but even in this case there are reasons to him to be afraid of her – protecting the territory, female attacks wings of the male. Therefore, to constrain her aggression, male presents the female with small gift – killed small animal. If the female is ready to pairing, she accepts it, and till some days animals keep together and sleep on one tree. For these days the male is coupled many times to the female and drives off other males from her. Then the female banishes him.
In the beginning of the next rain season female gives rise to one large, but helpless cub. The first weeks of life she flies to hunting with it, but later she starts to leave it in tree-trunk hollow. Development of the cub proceeds about four months. At this time it passes from parent’s milk to meat food and tries to catch small animals (insects and lizards) itself, not being able to fly at all. At the age of about 15 weeks the cub starts to study to fly, and in three weeks it leaves mother and leads independent life.
The young flying wolf reaches maturity at the second year of life. Life expectancy of this chiropteran reaches 30 – 35 years.

Swift-winged whiskered bat (Setostomops hirundipterus)
Order: Chiropters (Chiroptera)
Family: Molossid bats (Molossidae)

Habitat: South America, edges of tropical forests, woodlands.
Among mammals chiropters concede in variety only to rodents. At the boundary of Holocene and Neocene the part of species of this group had died out because of destruction of habitats – mainly because of destruction of tropical forests. But in any case some species were numerous enough, and in epoch of biological crisis the order remained various all the same.
In Neocene in plains and light forests of South America herds of herbivores wander – tapirotheres and huge coursing rodents – deermara and giant paca. Herds involve plenty of blood-sucking insects – flies, mosquitoes and midges. And rather large bat hunts for insects – it is an animal having wingspan of up to 50 cm and weighs of about 200 grammes. All bats are remarkable by more or less advanced outgrowths on muzzle, and also by ears frequently of strange shape – these are adaptations for echolocation. At this bat strange appearance is added with a plenty of rigid long bristles surrounding its muzzle. For this feature it has received the generic name “whiskered bat”, and the shape of wings is a reason of specific epithet “swift-winged”.
Wings of this little mammal are pointed; flight is fast and prompt with sharp turns. Tail of swift-winged whiskered bat is long; the interfemoral membrane includes it completely, but hind legs from knee and below it are free of membrane.
This bat eats large insects which gather around of representatives of megafauna. For prety catching animals of this species have got the special adaptation: around of their mouth resilient hair grow, increasing trapping surface. The similar adaptation is present at basket-mouths and lustrer birds of Apodiformes order, living in Central and Eastern Asia, and it represents an example of convergence – at representatives of different classes from germs different by origin organs similar by function are formed.
Muzzle of swift-winged whiskered bat is very freakish. The nose of animal is short, and narrow nostrils are extended vertically and almost parallel to each other; the top of nose is slightly below forehead. Edges of nostrils are mobile; nostrils can open or close as narrow slot. Small eyes are directed forward and are located at height of half of length of nostrils. Upper lip is splitted by vertical cut, and its halves can move independently from each other. Edges of upper lip hang down and are covered on edge with eresilient trapping hairs. The same hairs grow on the bottom jaw. When animal opens mouth during hunting, halves of upper lip shift in sides, and the bottom jaw moves downwards. Bristles, sticking in sides, form a funnel directing the met insects right to the mouth.
During the feeding this bat utters echolocating signals with the help of nostrils. Ears of this species are small. They are pressed to the head and are opened as two slits closed on top of the head – tips of ears are densely pressed to each other, and the forward line of ear adheres to head with the help of skin membrane.
Body and head of animal are covered with bright rusty wool. Male differs from female in larger size.
Swift-winged whiskered bat is crepuscular and nocturnal animal not competing to diurnal insectivorous birds. In day time this bat hides in hollows. It forms small congestions numbering up to 20 – 30 individuals. These groups have rather constant structure – no more than 20 % of individuals changes for one year.
Seasonal prevalence in breeding of whiskered bat is not present. One cub is born by female in any season, but more often it happens in autumn months, in rain season. Young individuals become capable to breeding at the second year of life. Up to this time their wool differs by colouring from wool of adult individuals – it is darker and dimmer.

Megaardvark (Megaardwark armatus)
Order: Aardvarks (Tubulidentata)
Family: Aardvarks (Orycteropodidae)

Habitat: Zinj Land, light forests and tropical woods.
Having African origin, the order of aardvarks never differed in variety, and distribution of these animals was always limited to area of warm climate. These animals are specialized in feeding on insects though by biochemical parameters they are close to ungulates.
When the East-African subcontinent, or Zinj Land had splited off from Africa, among its inhabitants there were aardvarks (Orycteropus afer). These animals could go through the time of biological crisis, because they lived not in woods, but in savanna, and social insects which these animals ate, were kept in enough. Gradually the climate changed, and the significant part of the area of Zinj Land was occupied by tropical woods. The descendant of aardvark – the megaardvark, very large insectivorous animal, inhabits these areas.
Megaardvark is a plantigrade animal moving on hind legs and resembling old-fashioned reconstruction of any dinosaur. The body length of megaardvark including tail makes up about 3 meters, and height in a waist is up to one and half meters. The long tail of animal similar to tail of kangaroo, but thicker, counterbalances forward part of body. When the animal eats to satiety, in tail the stock of fat is accumulated. Features of locomotion of megaardvark are reflected in structure of its skeleton. Sacral bone of this animal is large; some last lumbar vertebrae and first tail vertebrae are fused with it to unite rigid structure. Hind legs of megaardvark are very strong and brawny. If necessary the animal is able to run, but speed of its run is only about 20 kms per hour. The massive animal can not run long, and runs keeping such speed only about from hundred to two hundred meters.
If the megaardvark is attacked by predator, the animal prefers to not seek safety in flight and to protect itself with the help of its main weapon. Forepaws of this animal are armed with constantly growing thick claws. At this one 3-rd and 4-th fingers on which claws reach the length of 20 cm are especially strongly advanced. Usually megaardvark walks, having pressed forepaws to chest. Occasionally animal bases by claws on the ground, especially during the feeding. But the main function of claws of megaardvark is not defense, but destruction of nests of social insects, ants and termites. Besides megaardvark breaks by claws rotten trunks of trees in searches of grubs, and digs out wood litter. In addition to insects it eats spiders and even small vertebrates – frogs, lizards and nestlings of birds nesting on the ground. The megaardvark is convergently similar to huge stegoechidna from tropical forests of Meganesia, but does not eat the vegetative forage.
Megaardvark is specialized to eating of insects and other small animals. It has weak bottom jaw and very small mouth on the tip of long narrow snout. Teeth are strongly reduced and presented only by three or four pairs in each jaw. They represent cylindrical formations with thin layer of dentine and easily erased soft pulp. The animal frays caught animals by them. Tongue of megaardvark has very remarkable structure. It is very long – the tongue is able to extend from the mouth more, than to half-meter. The basis of tongue is shifted far back, and attached to brest, as at anteaters of Holocene epoch. Tongue consists of elastic muscles, and inside it the thin sinew retracting the tongue in mouth is stretched. The surface of tongue is covered by large knobs and small corneous thorns between which glands emitting sticky secret are located. Such tongue allows not only to extract insects, but even to pull small lizards and frogs out from holes.
Insects are not safe forage. Many kinds of social insects, which are searched by megaardvark, are armed sharp mandibles, and ants have also poisonous glands. Poison of some ants eaten by megaardvark, can easily kill cat-sized animal. For protection against insects nostrils of megaardvark can close with the help of special ring muscles. Eyes are another place of this animal vulnerable for attacks of insects. Eyes of megaardvark are small; they are protected from casual penetration of insects by dense rigid eyelashes. At megaardvark there is bad sight, but it does not prevent it to live normally. Sharp sight is not so necessary for life in rich and shady tropical forest. This animal searches for forage with the help of very keen sense of smell, and the hearing provides it the additional information about the world around.
The wool of megaardvark is thin and rough, similar to pig bristle. The whole body of animal is covered with thick and strong wrinkled skin which can not be penetrated through by mandibles of insects. Besides on back of this sluggish animal some rows of dermal ossifications (as at fossil ground sloths like Megatherium) are developed. The predator, risked to attack megaardvark, risks to break teeth biting to its back. The adult megaardvark practically does not have enemies.
This animal usually eats termites and ants, destroying their nests. This is one of few animals of Zinj Land which is not afraid of vagrant ants. Except for them, megaardvark digs out digging insects from wood litter and searches for larvae in rotten wood. Megaardvark often feeds on carrion and rests of prey of local predators. It can not tear off and swallow pieces of meat, but all the same it finds a lot of edible things on the rests of carcass – megaardvark eats maggots and grubs developing on it. High acidity of gastric juice makes such diet of animal safe, protecting it from bacterial infections.
The ancestor of megaardvark was well-known for skill of hole digger. Megaardvark had practically left this skill. For spending the night the animal digs to itself non-deep hole in wood litter, usually near the fallen tree. These animals are solitary ones meeting only for pairing. Seasonal prevalence in breeding of megaardvark is not expressed. Pregnancy lasts till about 17 months. Once in two years the female gives rise to one large cub. It has soft skin, and dermal ossifications are poorly advanced. Therefore the cub of megaardvark is very much vulnerable not only for predators, but even for vagrant ants quietly eaten by adult animal. However it is born well advanced, and in some hours after birth is able to follow mother. The female looks at it within approximately 7 months (at this time she pairs once again). The young megaardvark becomes able to breeding at the age of about five years. Life expectancy of this animal is more than 60 years.

Forest horned cony (Ceratohyrax prolongocornis)
Order: Hyraxes (Hyracoidea)
Family: Hyraxes (Hyracidae)

Habitat: Zinj Land, various kinds of plain and mountain forests.

Picture by Alexander Smyslov

In early Neocene, after extinction of significant part of species of ungulates, representatives of earlier not numerous and uniform group of hyraxes had got an opportunity to show their evolutionary potential. Among them representatives of separate phylogenetic line of running hyraxes had appeared – subfamiliy Dromohyracinae in Hyracidae family. These animals gradually passed from burrowing habit of life to existence in plain district. After great split of Africa the part of species of this group had remained on continent and evolved to giant species. And the species isolated at the East-African subcontinent, had changed much less. At Zinj Land representatives of this basal group of hyraxes had remained.
In forests growing on plains and in foothills one of such species of running hyraxes lives. Its distinctive feature is a presence of pair of short horn-like outgrowths on head; because of this feature the animal has received the name forest horned cony. This is a pig-sized ground mammal: it weighs about 50 kg at body length up to 70 cm. Legs of animal are longer, rather than at common hyraxes of Holocene epoch, and forest horned cony is able to run quickly. Hand and foot are digitigrade. Despite of massive constitution, animal dexterously jumps over high plank-buttress roots of tropical trees, escaping from chasing of predators, and is able to change direction of run sharply. By habit of life it resembles caviomorph rodents of South America like agouti or paca very much. This animal lacks tail appreciable from outside.
Bones of upper part of skull of forest horned cony are thickened and form a kind of helmet. On nose bridge of animal two conic horns directed upwards and forward grow; these structures are covered with dense cornificated hairless skin. Both males and females have them, and their application is various: at males horns serve for courtship tournaments and establishment of domination out of breeding season, and representatives of both genders also use horns for digging holes and protection against enemies. The attacked horned cony, not having an opportunity to escape in flight, attacks on predator, and strikes impacts by head, ramming the aggressor. Small eyes are slightly shifted downwards and protected by edges of bone “helmet”.
Colouring of wool is dark brown with white spots on sides of head and on stomach. Male and female do not differ in colouring. The cub does not have white spots.
Forest horned cony lives in family groups consisting of large male, several females of various ages and their cubs. Shelter for family of animals is the hole about half meter wide and over ten meters long, directing under ground to almost three-meter depth. In hole there is well equipped inhabited chamber covered by vegetative material, some temporary toilet holes where animals leave dung and urine, masking their presence, and 2 – 3 carefully disguised emergency exits.
These animals do not have seasonal prevalence in breeding, and in family group always there are cubs of various ages. Pregnancy lasts till about three months. The female gives rise to 3 – 4 well advanced cubs born with opened eyes. They become sexually mature at the age of about two years.
At Zinj Land close species of horned conies live:

Picture by Alexander Smyslov

Mountain horned cony (Ceratohyrax crassipygus) lives in mountain areas of Zinj Land, preferring dry bushy districts and thickets of grasses. It is larger, rather than forest horned cony, because it lives in cooler climate with expressed daily and seasonal fluctuations of temperatures. At cold snap this species runs to not deep dormation. In warm season when food is plentiful, on buttocks of mountain horned cony thick layer of fat is accumulated; it is used in winter time. Colouring of wool at this animal is lighter, than at forest species – straw-coloured with grayish shade on back, hips and waist. Horns on skull are thicker and shorter, than at forest species. With their help animal can pick out from the ground stones during the hole digging. This species settles in pairs, but does not avoid presence of congeners.

Picture by Alexander Smyslov

Dwarf horned cony (Ceratohyrax minimus) inhabits high-mountainous meadows of Zinj Land. It is a marmot-sized species weighting no more than 6 kgs. It has short horn-looking outgrowths of skull, and rich wool has dark, almost black color without marks both at adult individuals, and at cubs. This animal is able to climb and jump on rocks, searching for grassy plants. In summer dwarf horned cony also accumulates fat which is depositing on buttocks and hips. In conditions of high mountains at downturn of temperature it runs into deep dormation which lasts not less than 3 months. At this time animal uses the saved up fat stocks.

Sluggish ventrohyrax, “Zinj sloth” (Ventrohyrax bradipus)
Order: Hyraxes (Hyracoidea)
Family: Ashkokos, or Climbing Damans (Ascendohyracidae)

Habitat: tropical woods of Zinj Land.

Picture by Timothy Donald Morris

In epochs of climatic changes some types of vegetative communities may completely disappear, dooming to extinction the significant part of species connected to them. But at restoration of acceptable conditions of inhabiting settling of again formed community can proceed by two ways. In one case it is occupied with descendants of relic species had escaped in few “refuges” where the former vegetation had kept. In other cases new habitats are accustomed by the species earlier not dwelt here. It had taken place, for example, at the East African subcontinent (Zinj Land) where in tropical rainforests the original analogue of sloth descending from one local group of animals had appeared.
For Zinj Land the special family of climbing damans, not meeting in continental Africa, is typical. Its characteristic representative is ashkoko (Ashkoko sylvaticus) - animal similar by constitution to loris - Asian prosimians of Holocene epoch. But this animal is not so specialized to tree-climbing habit of life, as ventrohyrax – another animal living in the neighbourhood.
The name “ventrohyrax” means “a stomach of daman” and emphasizes characteristic position of this animal – upwards a stomach. Ventrohyrax hangs under the branch similarly to South-American sloths, for what it had received another name – “Zinj sloth”.
In connection to unusual way of life in anatomy of ventrohyrax there is a number of interesting features. Paws of animal are adapted to clinging to branches – they are rather long, and the structure of hand and foot differs in prominent features. Hand and foot of animal are lengthened (their length is about one third of general length of the extremity), along their bottom side strong sinews stretch, which are attached to strong muscles. For attaching of muscles on paws bones of ventrohyrax crests giving to bones fantastical appearance are advanced. Fingers of ventrohyrax are very long and tenacious – animal clings by them to branches, because claws became very small even at damans – far ancestors of these animals. On forepaw two fingers are kept (only 2-nd and 3-rd, and other ones, 1-st and 4-th fingers are reduced and do not touch to branch), on hinder leg all three toes are kept. Fingers and toes are bent like hooks; skin on palms and feet is naked, covered with cross plicas and callouses. Due to this adaptation animal easily moves even on prickly branches. At grabbing of branch muscles automatically contract, and very strong capture is formed: even the died animal remains hanging on branch, yet will the decomposition of corpse begins. Muscles of extremities of ventrohyrax have unusual dark red color: they contain many myoglobin – the substance accumulating oxygen, therefore they can work any time in “automatic mode”.
Ventrohyrax spends all life among branches, and extremely seldom goes down to the ground. On the ground this animal is very clumsy: ventrohyrax bases on back surface of hooked fingers of forepaws and external lateral surface of foot (ends of toes are turned under the body). The animal walks on the ground slowly, and as soon as possible tries to find a tree suitable to life to appear again in world habitual for itself.
The neck of ventrohyrax is very mobile; due to it animal can eat leaves around of itself, staying at one place. Muzzle of animal is short and wide; molars are tuberculous with wide masticatory surface. Chewing muscles of animal are well advanced: in case of necessity ventrohyrax can bite out small branches. Ventrohyrax had kept features of dental system characteristic for the daman: in each jaw it has two constantly growing self-sharpening incisors.
Ventrohyrax is covered with shaggy wool – though it lives in tropical climate, it may easily catch a cold. In equatorial area each day rain may fall, and only foliage of trees protects ventrohyrax from it. And in wood canopy strong winds blow frequently. The wool of ventrohyrax is colored brown with darker separate locks, precisely imitating the pattern of wood bark. The wool of animal serves as fine masking. Only it and powerful impacts by claws are its unique protection against predators. Defending itself, animal seizes branch by hinder legs and defends by both front paws.
Though ventrohyrax spends all life on branches in tropical forest canopy, this animal does not make risky and fascinating jumps from tree to tree, and in general it differs in slowness. At such habit of life three-dimensional sight, characteristic for damans, loses the value, but the wide field of view gets much more value for life. Therefore eyes of ventrohyrax look more in sides, than forward.
Ventrohyrax leads rather simple way of life and consequently does not differ in high mental faculties. Its brain is too small, and brain department of skull is lengthened and low.
Though the forest canopy is very productive part of tropical wood, here there is very rigid competition for food resources. In forest canopy a lot of different mammals, consuming various kinds of forage lives. The close relative of ventrohyrax, ashkoko, is omnivorous animal, and other climbing animal, sun flying fox of chiropters order, eats mainly fruits. Ventrohyrax does not compete to them due to the diet: this animal eats exclusively leaves. Being a sluggish animal, not needing for long jumps and fast climbing, and having no big expenses of energy, ventrohyrax eats poorly nutritious and hardly digestive leaves of plants. In such way it avoids a competition for food with other animals. The stomach of this animal is complex and consists of several chambers. In the most voluminous first chamber there is a food fermentation, in which symbiotic bacteria and protozoans help ventrohyrax. Ventrohyrax easily digests even dense leaves of figs, rich in rubber.
This species is social; it keeps in tree crones in groups of one male and several adult females with cubs. The structure of these groups is changeable, and animals are not connected with strong ties of attachment (except for female and growing up cubs). Frequently groups of animals, travelling in forest, unite or break up. Also there are single males joining groups only for pairing.
Two times per one year the female of ventrohyrax gives rise to one cub. It is well developed, covered with wool, with opened eyes. Color of wool at the cub is darker than at female. Till first days of life the cub clings to mother and eats only her milk. Starting approximately from the week age cub of ventrohyrax starts to try vegetative food. At first the female feeds it with slurry of belched and semidigested plants. Young animal receives so necessary gastric microflora. Gradually the cub passes to feed in vegetative forage.
Young ventrohyrax becomes sexual matured approximately at the fourth year of life. Life expectancy of this animal reaches 30-35 years.

Ngoloko (Graviashkoko ngoloko)
Order: Hyraxes (Hyracoidea)
Family: Ashkokos (Ascendohyracidae)

Habitat: Zinj Land, tropical forests.
Among the Neocene mammals, the hyraxes order has achieved significant success in the struggle for existence. After the split of Africa and the separation of Zinj Land from it, the evolution of the descendants of the hyraxes continued independently on both landmasses. In Africa, massive land-dwelling forms – flathorns, embolohyraxes and ndipinotheres – predominate, and also semi-aquatic ipopos exist. Tree-climbing hyraxes – ashkoko and ventrohirax – evolved in the forests of Zinj Land. Along with them, the forests of Zinj Land are inhabited by other tree-climbing hyraxes, among which one of the largest is ngoloko, a very massive animal weighing about 150 kg. In its proportions, ngoloko resembles a bear with long paws, hence the name: among the peoples of Kenya, “ngoloko” is the name of an unknown animal, similar to a bear according its description. The animal’s body length is up to 120 cm.
Hands and feet of ngoloko are tenacious, with well-developed digits. The front paws are five-fingered, with a movable opposable thumb; the hind paws are three-toed. The nails are blunted and hoof-shaped. The surface of the soles and palms is covered with soft skin, providing a good fit to the surface, and numerous sweat glands moisturize the skin. Ngoloko climbs trees, grabbing branches with its front paws and clinging to the irregularities of the tree bark with its hands and feet.
The animal’s fur is short, bluish-gray, and there are several black longitudinal stripes on its back. The crown, nape and shoulders are black, and white spots are often visible on the muzzle above the eyes. Sometimes the spots merge into unite white stripe across the forehead.
The structure of ngoloko’s jaws is adapted for processing coarse vegetative feed. Animal has a large head with a short muzzle on a movable neck: ngoloko can easily turn its head 180 degrees when browsing tree branches around it. The animal’s jaws are short and wide. The animal’s dentition lacks diastema, all teeth are short, and the jaws can make lateral movements to chew food. The molars of ngoloko are tubercular and have a wide chewing surface; the incisors are strong, sharp, and constantly growing. Ngoloko easily bites and chews branches up to one centimeter thick.
Eating coarse vegetative food has become possible due to the peculiarities of the digestive tract. Ngoloko’s stomach is three-chambered, with a large anterior section, which is the fermenting part of the stomach. It is home to bacteria and ciliates that help the animal break down cellulose. Unlike ruminants, ngoloko does not regurgitate fermented vegetable matter for repeated chewing. Fermented food is processed by digestive enzymes and enters the intestine for further assimilation. The intestine in ngoloko is very long – about 15 meters. The animal has a well-developed cecum.
Ngoloko is an ecological analogue of ruminants in the forest canopy. It feeds on coarse vegetative food – leaves and young shoots, and it can bite non-lignified branches. Due to this diet, it has no competitors, but the same circumstance has caused it to increase in size: this is the only way the animal’s belly can accommodate the stomach and intestines, ensuring normal digestion of food. It is a slow-moving animal that cautiously climbs trees and prefers not to descend to the ground. This slow-moving animal often stays on one tree for a long time until it eats all the available branches on it. Ngoloko also willingly eats epiphytic plants and drinks the water that accumulates in their rosettes. To move to another tree, ngoloko cautiously climbs down to the ground or uses thick vines as a bridge. This animal is able to walk on the ground, but behaves very cautiously in this case.
Ngoloko’s natural enemies are large carnivores. This animal protects itself from them with bites. In addition, ngoloko often strangles the enemy with its strong front paws. The animal’s fingers clench automatically, and even the dead animal does not unclench its paws. If a predator manages to kill an ngoloko, the animal’s carcass hangs from a tree, literally clinging to it with a death grip.
Ngolokos are sociable animals, although they are solitary by nature. These animals have very loud voices, and the trachea forms a resonator outgrowth on the throat, which swells during the vocalization. The sounds produced by these animals are very diverse: barking, howling and chirping of various tones. In the morning, the animals “have a talk”, making loud howls almost continuously for 15-20 minutes. Animals also leave odorous marks on branches and trunks, rubbing their backs against them: an odorous gland is developed on the lower back, which secretes a paste-like substance with a musky odor. These animals do not occupy any particular territory and are often found together during feeding. During such meetings, mating takes place.
The female gives birth once a year to one large, well-developed cub, which differs from the adult individuals in its darker coloration. It stays with the female for a long time and feeds on milk for up to 4 months, but quickly begins to eat adult food. The female often regurgitates “rumination” of fermented plants for the cub, passing along with it a “starter culture” of representatives of the gastric microflora. At the age of 8 months, the young animal is already completely independent, but still remains with its mother, and at the age of one year begins to lead an independent life. Puberty occurs at the age of 4 years, and life expectancy reaches 30 years.

Ishisonga (Platyceratherium ishisonga)
Order: Hyraxes (Hyracoidea)
Family: Flathorns (Platyceratheriidae)

Habitat: Equatorial Africa, lakes and rivers in the forest zone.
The mass extinction of megafauna, which began as early as Holocene as a result of human activity, reached its peak in Early Neocene, when climatic changes caused the extinction of the residual populations of many survived species. This circumstance has opened up many opportunities for evolution for small animals that used to live in the shadow of the giants of the past. There were hyraxes among them – unusual animals similar to hamsters or guinea pigs, but related to elephants and sirenians, which did not live up to Neocene. The role of sirenians in the seas was taken by the descendants of American rodents. The descendants of the hyraxes turned out to be much more diverse; they inhabit Africa, Zinj Land and tropical Asia, occupying various ecological niches.
There are several branches of the descendants of hyraxes in Neocene. There are tree-climbing species among them, and sometimes these are very specialized ones. There are species similar to Miocene Chalicotherium, semi-aquatic and cursorial species. The flathorn of African savannah is one of the less specialized species, and further south, in the swampy forests of the Congo basin, a related species, the ishisonga, lives (the name means a mythical African beast).
Ishisonga is a fairly large beast – it grows up to 3 m in length, and weighs up to 2 tons. Its legs are relatively short and thick, and its digits are widely spaced and equipped with a wide pad of elastic tough fat-impregnated tissue. The claws are blunted and hoof-shaped. Despite its large size, its physique is quite “slender”. Unlike many members of its family, the skin of this species is actually hairless: the hair is short, thin, and grows very rarely. Only a hair tuft grows on the tip of the tail, with which help ishisonga scatters manure to indicate its presence and mark its territory. The eyes and ears are small, and the animal is short-sighted, but it has good hearing. The head is shortened and wide. The upper part of the skull in females represents a solid bony “roof” covered with keratinized tissue. The male has two horns on his head – on the nose bridge and on the crown. Their bases merge with each other, and the horns of adult animals form a unite structure resembling one horn with two tips one after the other. When the animals butt heads, their horns lock, and the animals try to turn each other’s heads and knock down the opponent. The neck muscles of males are powerful, and a hump rises above the shoulders from the vertebral appendages to which the muscles are attached.
Ishisonga is a herbivorous animal, but it is quite territorial and aggressive, especially on land. During the day, it usually rests in the water or hides in the shade in the coastal thickets, because its skin, although durable, burns in the sun easily: ishisonga leads a twilight and nocturnal lifestyle.
Ishisonga lives in harems: as a rule, it consists of one adult male, his females and offspring. He treats young males with tolerance until they grow to 150-175 cm in length, entering adolescence. After that, the male begins to drive them away from him and the bond with the mother breaks completely after she has a new cub. Young animals leave their parents and look for an opportunity to create their own families. Ishisonga males willingly accept other males’ young females into their harems, providing them with protection from predators. Young males most often form bachelor groups. As part of these groups, they behave relatively peacefully, but the appearance of females forces them to show aggression towards each other in the struggle for a female. The animals fight with each other using horns growing on their heads; such horn resembles a horn of a flathorn, but it is narrower, especially towards the end. Ishisongas use these horns to “fence”, striking with the side surface of the horn, rather than ramming the opponent. These animals are proportionally more muscular and mobile than their relatives, and blows of their horns can break the bones of smaller animals – when attacked by a predator, these animals fight back actively and can even chase a predator. Large African predators like the deadlynetta and barbed herzogcat attack and kill these animals on land. Ishisongs themselves are exclusively herbivorous.
By the peculiarities of family life, these animals are close to related species: every one and a half to two years females give birth to one cub; twins are very rare. The young live with their mothers and father until adolescence. This species needs watering holes, but if necessary, it can cover long distances on land, especially at night.
Puberty occurs at the age of 3 years. The life expectancy of ishisonga is 30-40 years or more.

Embolohyrax (Embolohyrax brontotherioides)
Order: Hyraxes (Hyracoidea)
Family: Flathorns (Platyceratheriidae)

Habitat: the north of Africa, Atlas Mountains, Western Europe to the north from the Alpes.

In human epoch large species of mammals got serious harm because of human activity. Hunting and destruction of habitats had resulted in great reduction of their number and variety. The part of large species had died out even within people’s memory, and other species had become extinct soon after people extinction – their small and dispersed at the former area populations appeared invitable in conditions of the changing world meeting a new wave of congelation. In new landscapes of early Neocene the place of missed giants was occupied by new animals. Frequently they are descendants of ones grazed gingerly in shadow of Holocene giants left to the past. Hyraxes were especially successful from this point of view. Their descendants had quickly increased in size and had turned to prevailing group of large herbivores in tropics of Old World. The north of Africa, southwest of Europe, Near East and Hindustan became habitats of large species of this group.
To the north of savannas of Sahara, at the Gibraltar Isthmus and in Southern Europe at the edges of salt swamps and deserts of Mediterranean lowland one species of these animals, huge embolohyrax, lives. It is the close relative of flathorn (Platyceratherium foetidus) from savannas of Africa. Embolohyrax looks like rhinoceros, but has very large size: length of its body is over 4 meters, and growth at a shoulder is up to 170 cm. Weight of such giant may reach 8 – 9 tons. Constitution of this species is massive; limbs are digitigrade, with elastic pad of fatty tissue under fingers and toes. Front and rear limbs are three-fingered (three-toed), and on fingers/toes thick hooves grow. Embolohyrax lives in dry places, but if necessary it easily moves in marshes and is able to swim. This species is remarkable with its great ecological plasticity – embolohyraxes well feel like as in savanna and maquis the Western Europe, as in deciduous forests of the Central Europe and foothills of the Alpes. They equally well consume rigid bushes forming maquis, sapful foliage of undersized trees in hillsides in the Alpes and marsh grasses at water meadows of Central Europe.
This animal has bad sight, but very good hearing and keen sense of smell. Nostrils of embolohyrax are wide and supplied with skin valves. When animal gets in sandstorm or dives, valves close nostrils from sand or water. Wool of embolohyrax is thin and short, and skin of grey color reaches thickness in 4 – 5 cm, especially on shoulders and back of animal.
Like all flathorn relatives, embolohyrax has massive bone horn and very large head. Horn represents the massive bone outgrowth covered with corneous layer, and it stretches along the whole skull. In horn shape at this species the precise sexual dimorphism is expressed. At females horn represents a low bone thickening, the platen stretching along skull. Horn of female is covered with dense skin, and in its forward part, above a nose, there is a small expansion in horizontal plane. Male horn is much more massive and thicker. It is sharply expanded and curved upwards in forward part, from the level of eye-sockets. The forward surface of horn is covered with thick cornificated skin and represents the shock weapon – hence the name meaning “ram hyrax”. The bone tissue of horn is well adapted to endure significant loadings directed front to back; the basis of horn rests against well advanced cross occipital crest. At the end of summer the courtship season begins at embolohyraxes. At this time embolohyrax males establish hierarchical relations, butting each other by horn – it does not cause traumas to them. If struggle does not reveal the strongest one, or the contender behaves too arrogantly, males pass to more aggressive way of relations establishment, and butt each other’s sides by horn. As a result after courtship season males frequently get broken ribs, and at “battle veterans” the most part of ribs has traces of repaired traumas.
On back of embolohyrax there is large musky gland closed by skin valve. In courtship season it secrets oily liquid with sharp musky smell. Smells play the important role in communication and behaviour of these animals. The smell of female secretions raises male aggression, and male secretions serve for marking of territory and females. Leaving odorous marks, male rubs back and waist against stones and tree trunks. Usually mature males lead solitary life, and females gather in herds numbering up to 20 animals. In areas rich in forage males join herds of females and beyond courtship season are very tolerant to each other.
Pregnancy lasts till about 20 months. The cub is born in spring when female has opportunity to feed on vitamin-rich plants. At birth cub weighs about 200 kgs and is covered with appreciablly richer wool, rather than adult animals. It sucks mother’s milk up to two-year-old age, but right at the first autumn of life it tries vegetative food. Sexual maturity at young animal comes at the age of 4 years, and life expectancy reaches 60 years.

Ganda (Indoceratherium ganda)
Order: Hyraxes (Hyracoidea)
Family: Flathorns (Platyceratheriidae)

Habitat: forests of South and Southeast Asia, Hindustan.
In Early Neocene, hyraxes were one of the groups of mammals that realized their evolutionary potential in full degree. Large ground-dwelling and arboreal forms, and even peculiar analogues of sloths, evolved among them. Flathorns and related forms are among the largest descendants of hyraxes in the Neocene epoch. They are widespread in Africa north of the equator, and have penetrated into Europe via the Isthmus of Gibraltar. Through Western Asia, they managed to enter the forested areas of South and Southeast Asia, where several species of this group are also found. This “breakthrough” was carried out by representatives of the flathorn family.
One of the large species of flathorns lives in humid swampy Asian forests. This species is ganda, very similar to the rhinoceroses that lived in that area during the human era (the word “ganda” meant “rhinoceros” in one of the dialects of India). It is a large animal, with a shoulder height of over one and a half meters. Ganda’s physique is massive – columnar legs, barrel-shaped belly and large heavy head. The beast has wide hooves on its legs (4 on the front leg and 3 on the rear leg), which allow ganda to wander through swampy terrain without sinking. The tail of the animal is very short.
Ganda’s skin is covered with sparse hair, which is slightly thicker on the lower part of the body, where the skin is thinner. The shoulders are covered with almost hairless, thickened skin with a shock-absorbing layer of fat, forming a kind of “armor”.
The animal’s head is flattened, with a small braincase. The upper part of the skull is characterized by a thickened bone. Like its African cousin, the ganda has a large bony horn on top of its skull. Unlike the flathorn, the horn of the ganda is more extended forward and widened at the tip, forming a shovel-like structure with a slightly protruding front edge. The main part of the horn is located on the skull as a bony “roof”, forming two large bony bumps on the crown between the eyes and ears. To support the animal’s skull, strong neck muscles are developed, and the vertebrae of the cervical and thoracic spine are equipped with high upper spinous processes to which the musculature is attached. Large male with strongly developed horn has a hump above its shoulders, formed of muscles and vertebrae. Female has a smaller horn than male.
It is impossible to fight head-on with a horn like ganda’s, because it can easily break. During their tournaments, ganda males hit each other with their heads and horns on the shoulders, striking sideways with their heads. Animals of both sexes use the horn as a shovel to dig up aquatic plants in shallow river waters. Due to the peculiar shape of the horn, the animal’s nostrils open at the base of the horn on the sides of its head. They are equipped with valves that reflexively close when the beast is feeding.
Ganda prefers to live in swampy areas, often feeding in the water. This animal can dive well, digging up roots and tubers of aquatic plants even at a depth of three meters. In the water, ganda cools down in the midday heat and escapes from the stings of blood-sucking insects. Ganda also willingly eats coastal plants and large grasses growing in the undergrowth. The presence of ganda is revealed by wide trails trampled into the undergrowth, where nothing larger than moss and mushrooms grows. Trails connect water and the feeding grounds of the animal in the forest.
Adult ganda males tend to live alone, while young animals form groups. Also, the grown-up cub stays with the female for some time after the birth of a new one. Female gives birth to one cub every two years, twins are exceptionally rare.
Ganda reaches puberty in the fifth year of life, and life expectancy reaches 50 years.

Carcadann (Monoceratherium carcadann)
Order: Hyraxes (Hyracoidea)
Family: Flathorns (Platyceratheriidae)

Habitat: Asia Minor, the Middle East, the western regions of Hindustan.

Picture by Sauron

Large descendants of hyraxes belonging to the flathorn family are distinguished by the presence of bony growths on their heads, which are used as weapons or a means of displaying to rivals and predators. This group of animals is very characteristic of North Africa, Western Europe and South Asia, where they are ecological analogues of rhinoceroses and bulls of the human era.
Carcadann, one of the relatives of the African flathorn (Platyceratherium foetidus), lives in Southwest Asia. This representative of the giant ground-dwelling branch of hyraxes is well adapted to life in hot and arid climates. Carcadann differs from its African relative in its lighter build and long legs. The height of carcadann at the shoulders is about 160 cm, but the animal looks even larger due to the fact that there is a well-developed hump on the back formed by the upper spinous processes of the vertebrae and adipose tissue. Carcadann’s legs are plantigrade, and a pad of springy and elastic tissue is developed under the fingers and toes, allowing the animal to easily move over rocks and even walk on mountain slopes. There are still 4 toes on the front leg and 3 on the back. The digits end in small hooves.
The animal has a short tail with long hair, similar to that of a horse. The body is covered with short, thick hair, which protects it from overheating and makes it easy to tolerate the night cold. Wool color is usually brown, but there are some lighter individuals with ochre-red and even yellowish hair. There is a large scent gland on the lower back, which animals use to mark their territory by rubbing against rocks, trunks and lower branches of trees.
Carcadann has a large head, but a very small brain. The cranial vault is strongly thickened. A straight, long bony horn with a powerful base grows on the nose bridge; it is similar to the horn of the fossil Elasmotherium rhino. The tip of the horn is thickened a little bit and slightly forked – this is a sign of the distant relationship of carcadann and flathorn. Carcadann’s eyesight is poor, but this is compensated by a very fine hearing and a keen sense of smell.
Carcadann is a herbivorous animal capable of eating almost any plant. Due to the well-developed three-chambered stomach, carcadann can eat plants with milky latex containing a significant amount of gum. This animal can go without water for a long time. The fat from the hump serves to produce metabolic water, like in a camel. Carcadann can eat cacti and gnaw the soft wood of semi-succulent trees.
In areas favorable for life, carcadanns keep in herds numbering up to 20 individuals. In a desert area, these animals form groups of 3-4 adult animals with young ones. The leader of the group is usually an adult male; the composition of the group is constant from year to year. In a large herd, there are several males who establish dominance relationships and get along peacefully outside of the mating season.
Carcadanns are often found along the edges of the Mediterranean lowland and can descend into the basin through canyons formed by rivers. Occasionally, carcadanns can go far into the lowland desert, where they die of hunger and thirst if they cannot find their way back. This animal is able to run fast and can reach speeds of up to 40 km/h over a short distance. Carcadanns usually move at a foot’s pace, covering a distance of up to 50 km in a day, if necessary. Carcadanns do not tolerate dampness, so they only rarely enter the coastal areas of the southern shore of Fourseas.
The breeding season of carcadann comes at the end of the summer heat. The males butt heads with each other and display their horns. At this time, their specific gland begins to secrete a fragrant musky substance. When ready to mate, the female emits a milder, bitter odor, encouraging males to compete for her. The cub is born in the spring. It is well developed, covered with lighter hair than adults (with dark legs), and is able to stand on its feet within an hour after birth. The female brings offspring annually, but in populations living in less favorable conditions, this may happen once in two years.
A young animal reaches sexual maturity at the age of 5-6 years, and its life expectancy reaches 50 years.

Briareos, European ndipinotherium (Parandipinotherium europaeus)
Order: Hyraxes (Hyracomorpha)
Family: Ndipinotheres (Ndipinotheriidae)

Habitat: Western and Central Europe
Until man drastically changed the face of the Earth, the megafauna on almost all continents of this planet, except Australia and Antarctica, included mammals of Proboscidea order. Hunting and habitat destruction meant that these giants did not survive humans, but proboscideans had much smaller “relatives” – hyraxes, non-specialized ungulates similar to marmots and guinea pigs, which are the representatives of Hyracoidea order. The descendants of these mammals, which originated as early as the Eocene, formed four new families after the disappearance of most ungulates – the heavy-built flathorns (Platyceratheriidae), the gorilla-like ndipinotheres (Ndipinotheriidae), the gracile hyracolopas (Dromohyracidae) and the sloth-like ashkokos (Ascendohyracidae). Most of them inhabit the historical ancestral homeland of the group – Africa and Zinj Land that broke away from it, but some representatives of many of these African families also inhabited Eurasia. Only ashkokos are endemic to Zinj Land. If the easternmost species of Neocene hyraxes (ganda from the Indian jungle) belongs to the flathorns, then the northernmost representative of the order is the European ndipinothere.
Along with embolochirax, the European ndipinotherium, or briareos, is the largest mammal in Europe: its height at the shoulders reaches three and its length is four meters (hence the name – the name of one of the ancient Greek mythical giants). The weight of an adult male can reach up to 5 tons, females are smaller in size. The forelimbs of the beast are much longer than the hind ones; in this feature, as well as their massive physique, ndipinotheres resemble gorillas – huge primates that have become victims of human activity, as well as Neocene groundsloth rodents from Patagonia and kong from Southeast Asia. The hind legs of this species are very strong; standing on them, the European nidipinotherium can browse leaves at a height of five meters, which is beyond the power of any of the terrestrial animals of Europe. Head is wide and short, with a long, mobile neck; the ears are small. Most of the body is covered with light brown fur, but the throat and chest are colored white. Due to adaptation to the cold climate in winter, the coat of northern populations can grow up to 6-7 centimeters and the dense undercoat grows.
These animals live in herds, but their numbers are smaller than those of the savanna ndipinotherium – up to thirty individuals. This species has a pronounced matriarchy: the female matriarch and her sisters and daughters form the basis of the herd. Other females have a subordinate position, while males often move from one herd to another, and only temporary hierarchical relationships develop between them.
The basis of the briareos’s diet are leaves and, less often, branches of trees, which can be torn off by II and V fingers, which can oppose to III and IV fingers (on which the animal supports when walking), as well as huge incisors resembling those of rodents and inherited from their ancestors. An adult animal eats from one and a half to three hundredweight of plant food per day; therefore, in order not to destroy all vegetation in the area, herds of European ndipinotheres do not stay in one place for long. Due to this, Neocene Europe is a mosaic landscape, rather than solid forests, which contributes to the growth of biodiversity in this part of the world. Due to its huge size, a healthy adult of this species is inaccessible to any of the predators, but for young, ill or old animals, the mechka, the European subspecies of berl, can pose a threat.
Due to the seasonality of the European climate, the breeding season for European ndipinotheres begins in early spring. At this time, special glands on the back, also inherited from the ancestors, produce strong-smelling secretions. Males roar loudly, standing on their hind legs, and fight with each other, sometimes even with the help of their front paws, which can lead to injuries.
Pregnancy lasts about a year, so the cub is also born in early spring. This allows it to reach a large enough size before the end of autumn to survive the winter. Already at birth, the cub reaches a significant size – about 100 kilograms; it is well developed and tries to walk soon after birth. Usually one cub is born, twins are extremely rare. The cub is fed with milk for about six months, and for the same time (until next spring) it stays close to its mother, after which she expels it. European ndipinotheres reach sexual maturity at 5-6 years of age, and they are not inferior to elephants in their longevity – some individuals can live up to 60 years.

Xenondipina (Xenondipina agilis)
Order: Hyraxes (Hyracoidea)
Family: Ndipinotheriums (Ndipinotheriidae)

Habitat: marsh forests of Central Africa.

Picture by Tim Morris

In Neocene in territory of Africa to the south of Sahara evolution of hyraxes proceeded actively. These animals have considerably increased in size and have got various specializations. Among descendants of hyraxes animals of ndipinotheres family are remarkable – these are large herbivores, similar to gorilla in constitution. Large ndipinotheriums inhabit mosaic landscape where sites of forest alternate with open area. And xenondipina, the relict of early stage of family evolution lives in continuous tropical forests of Central Africa. As against to typical ndipinotheriums, it is not so large animal capable even to swarm up trees. Body length of xenondipina is about 2 meters. By its constitution it is similar to gorilla – front limbs are elongated, back is appreciablly inclined back, tail is lack absolutely. Hind legs of xenondipina are plantigrade and have three large claws. Forepaws are digitigrade; animal supports on 3-rd and 4-th fingers having little peaked hooves. Mobile 2-nd and 5-th fingers help animal to keep food. This is sluggish, but mobile animal – adult xenondipina is capable to swarm up trees and eats foliage, and if necessary it swims well enough and walks on fenny ground.
Head of this species is lengthened – xenondipina eats soft sapful vegetation for which chewing significant efforts are not required. Animal has rounded mobile ears, larger than ears of ndipinotheriums. Xenondipina has keen hearing and sense of smell, but its sight is bad. In rich forest it is difficult to be guided with the help of sight, and animal is helped more by other senses.
Body colouring of xenondipina is cross-striped: on brown background on shoulders, back and crupper close and thin vertical strips of white color stretch, forming slightly wrong striped pattern imitating spots of light and shadow on tree trunk. On throat of animal there is a white spot which helps animals to distinguish each other.
Xenondipina avoids competition to ground monkeys due to life in swampy habitats with set of fenlands and rivers – this species is especially numerous in Congo basin. Xenondipina eats foliage of trees, and frequently gets on trees to the height up to 10 meters. Also it supplements diet with marsh vegetation and digs out tubers of perennial grasses by forepaws. Frequently xenondipina goes for feeding to glades formed by fallen trees, and eats leaves of large grassy plants appearing at initial stage of forest restoration.
This species eats rough vegetative forage from which it is difficult to take nutrients. Stomach of xenondipina is specialized and two-chambered. Its first section is “fermentive chamber” where symbiotic protozoans and the bacteria, providing initial stages of cellulose digesting, live. In second, ferruterous section of stomach food is processed by digestive juice and the further digestion proceeds in long intestines.
Xenondipina keeps in herds numbering up to 20 individuals – adults males, females and their posterity about the second year of life. Between males the certain hierarchy is established, and dominant male has the right of priority in pairing. But subordinate males also have an opportunity to leave posterity. After 5-month long pregnancy female gives rise to well advanced cub which in one hour after birth is capable to walk, and at monthly age does not concede adult animal in dexterity of tree-climbing. At the second year of life young animals leave parental herd and join groups of animals of the same age, living at the edge of territory of herds of adult individuals. At three-year age xenondipina becomes sexually mature, and life expectancy of this animal makes till 30 years.

Sea ipopo (Behemohyrax littoralis)
Order: Hyraxes (Hyracoidea)
Family: Ndipinotheriums (Ndipinotheriidae)

Habitat: Africa, Zinj Land (ocean coast), coast of Tanganyica passage.

Picture by Alexander Smyslov

In Holocene sea habitats were populated by mammals of three orders: cetaceans, Carnivores (pinnipeds represent not uniform group, but descendants of several branches of land predators) and sirens. First two groups were submitted by carnivorous and planktophagous forms and sirens were sea herbivores. In Cenozoic it also had exist the order of sea ungulates Desmostylia, but it had died out long before the people occurrence. Hunting and reduction of places of inhabiting, caused by human activity, and also climatic changes and “plankton accident” at the boundary of Holocene and Neocene had resulted in complete disappearance of the majority of representatives of these orders. Only separate relic species of “old” orders had remained. But in Neocene mammals had made the second attempt to develop sea habitats – various groups of mammals in different areas of Earth passed to life in sea independently from each other. So, in Europe the flattooth, the species of semi-aquatic boars had appeared. Sirens led the origin from African mammals close to proboscids, and in Neocene the similar situation had repeated again in Africa. Descendants of damans, also related to proboscids, are one of succeeding Neocenic mammals. And among them animals leading semi-aquatic habit of life had appeared.
At coast of Indian Ocean one of representatives of water herbivorous mammals lives. This large animal is the descendant of damans by anatomy, but by ecology it represents the analogue of fossil mammal Desmostylus. It browses in mangrove thickets and at sea shallows, eating leaves of mangrove trees, seaweed and sea grasses. Systematical position of this animal is between flathorns and ndipinotheriums, but by features of anatomy this mammal is closer to the last ones. By size this four-footed animal is larger than rhinoceros, and is externally a little similar to hippopotamus. Because of it there is its name – sea ipopo (“ipopo” is the form of word “hippopotamus” distorted in African languages).
Sea ipopos meet in areas of warm climate, and their distribution in many respects coincides with area of mangrove woods growth. The body of ipopo is covered with short wool, and under skin the layer of fat improving buoyancy is advanced. Tail is absolutely not present at this animal. The wool on body is light grey – it makes the swimming ipopo less appreciable on the background of sea water. On forehead and nose bridge the black wool grows. At swimming animal they are above water, and do not give out this animal to underwater predators. The amount of black wool depends on hormonal level of animal, and it is possible to determine approximately the status of each individual in group by size of black spot - at dominants black “cap” is largest.
Legs of ipopo are rather long (near to it the flathorn looks stumpy) but this animal can not rise on hinder legs (like ndipinotheriums), and moves exclusively on four extremities. Forward legs are little bit longer than back ones, and back is sloping. Feet are wide, adapted to walk on fenny dirt and to row at swimming. Hoofs on toes are flattened, similar to elephant’s ones; under foot the fat pillow softening steps and increasing the area of support develops. Due to such structure of legs ipopos easily browse in mangrove thickets where any predator can not reach. Ipopo swims very well – it lives at all small islands near coasts of Africa and Zinj Land, and separate animals even regularly reach Madagascar though a stable population of ipopos had not appeared on this island.

Head of animal is large, rounded, with short jaws. Eyes are located in forward part of skull. Neck at ipopo is mobile – animal easily feed with branches of mangrove trees. Ears are rounded, mobile and short. The upper lip of ipopo is adapted for browsing of parts of plants: it is flexible and represents small proboscis, as at rhinoceros. The end of lip is slightly forked, permitting this animal to break even thin stalks dexterously. Simultaneously teeth of animal enable it to eat food of other kind – containing the big amount of mineral substances. Incisors in bottom jaw of ipopo are wide, scraping by type. They have deep roots and constantly accrue. Sea ipopo frequently leaves mangrove woods and goes to shallows, where eats seaweed, sea grasses and sedentary animals (in this habit it is the convergention with the European flattooth). Due to universality these animals can live where mangrove trees do not grow – at the rocky shallows overgrown with seaweed.
On back of ipopo there is the specific gland – it is the heritage remained from damans. With its help animals submit each other chemical signals, and dominants mark territory of herd. In mangrove woods they rub backs against low thick branches of trees, and among rocks they prefer to mark stones forming the similarity of eaves under which it is possible to stand.
Sea ipopos wander in herds on coasts, preferring the territories overgrown with mangrove trees. On rocky sites they also live, but each group has extensive territory – some times larger, than in mangrove wood. In herd of ipopos strict matriarchy dominates. Males of this species live one by one or in small groups in boundary territories of female herds. At bare coasts males live one by one and follow herds of females.
Pairing at ipopos occurs at any time of year. Pregnancy lasts about 15 months. In litter there is always one cub. But it is very well advanced, and rises on legs in first some minutes after birth. It is born on the coast; during the cub birth the female is surrounded by neighbours protecting her from possible enemies – at this time they rush even to sea birds. When the cub rises on legs, the female licks it, and some time does not let neighbours to it. After between the female and cub connection was established, other neighbours sniff newborn cub. They as though “accept” it so to the clan, and if necessary protect it in common. Therefore the survival rate of posterity at ipopo is high. But the cub depends on mother for a long time – it leaves her only at the third year of life and then she begins able to bear posterity again. For all life at the ipopo female it may be 4 – 5 cubs. The young animal becomes able to breed at the age of 6 – 7 years.
This species has more primitive relative, reed ipopo (Behemohyrax calamophilus) eating riverbank vegetation in rivers of Africa. It lives in marshland at riverbanks. The basis of food of reed ipopo is made with papyrus and other huge grasses. This is sluggish peaceful animal little bit smaller by size then its sea relative. The skin of ipopo has striped colouring – on light brown background there are vertical dark strips. Due to such colouring animal easily masks in thickets. Tip of muzzle at animals of both genders is white.

The role of reed ipopo in ecosystems of African rivers is great – these giants, eating papyrus and other plants, preserve rivers from overgrowing. On lighted by them sites of thickets of papyrus soon larger sprouts of this plant appear. Reed ipopo digs out plants from a bottom of river by strong forepaws for what the claw on internal finger of his forepaw is especially strongly advanced. By this claw reed ipopo “ploughs” river bottom, and then eats roots, tubers and sappy stalks of water plants emerged on water surface. As well as the sea neighbour, this is the social animal. But this animal lives in families in which there is a male. Male and main female mark territory by musk secretions of back gland.
Possible, the ancestor of these species lived in rivers and lakes, and then had settled down the current of rivers at first to deltas, and then to the sea coast, having the respective alterations in habits and diet.

Fast hyracolopa (Hyracolopa velocipes)
Order: Hyraxes (Hyracoidea)
Family: Running damans (Dromohyracidae)

Habitat: savannas of Northern Africa.

Picture by Tim Morris

Unspecialized species of live creatures are one of main reserves of evolution during mass extinctions. Absence of dependence on any limited resources and the ability to live in various conditions of environment are main “secret weapons” of such species. And anatomical primitiveness, characteristic for similar animals, comprises a potential opportunity for realization of various specializations in aspect of anatomy.
Among African animals damans (Hyracomorpha) were such group: they had represented the order of rather ancient and rather primitive hoofed mammals. In Neocene, after mass extinction, they had formed within the limits of order some groups, differing by habit of life. One group is presented by massive ground tetrapods – flathorns from Northern Africa. The second group specialized to tree-climbing way of life and became analogues of lower primates like lories and lemurs. It is ashkoko (Ashkoko sylvaticus) from Zinj Land, or the East-African subcontinent. Except for them, in mountains of Central Africa, savannas of Northern Africa and mountains of Southern Europe representatives of the third branch of damans – running antelope-like forms, hyracolopas, live. They occupy an ecological niche of small and medium-sized antelopes, partly competing with harelopes of northern origin.
By constitution hyracolopas are similar to typical antelopes, but in closer examination they have some obviously differences. Tail at hyracolopas is not present: it was reduced at their ancestors, damans. Rear legs of these animals are little bit longer than front legs because of what the back of hyracolopas is slightly inclined forward. This is the heritage of their past way of life: obviously, hyracolopas evolved in mountains of Central or Eastern Africa, and such structure of body is typical for animals grazing on hillsides. The structure of legs uindicates these animals are rock-climbers and runners. Extremities of damans were plantigrade, and foot of rear leg had formed similarity of sucker. At hyracolopas such adaptation had disappeared: on back side of rear leg there is only a callous, permitting to sit on stones. Claws had increased and became similar to small hoofs. As against horses and antelopes, hyracolopa supports not only on hoof-like claw, but also on the subungius covered with thick cornificate skin. Lateral toes became small, and touch the ground at movement only a little. On forward leg only two fingers from four, characteristic for daman, remained: second and larger third ones.
Head of hyracolopas is lengthened and low, eye-sockets are shifted in forward part of skull. Brain cavity is low and long, that clearly indicates on – alas! – low intellectual qualities of these animals. But at top of skull small sagittal crest stretches, to which strong chewing muscles attach. In dental system of hyracolopas features, characteristic for ancestors are kept: gnawing type of incisors. The bottom jaw is short and a little bit “lengthened” by two large incisors. With their help hyracolopas can dig out bunches of grass with roots. If necessary incisors turn to fighting weapon: at the attack of small predators hyracolopas can bite strongly.
At hyracolopas there are large eyes providing good sight. At mountain species eyes look forward, rather than in sides: so the three-dimensional sight, which helps to estimate distance before jump, is provided to an animal. Hearing at hyracolopas is good; ears are big, rounded and mobile. Sense of smell is advanced well: nasal cavity is short, but high. Smells play the significant role in life of these animals: on back of hyracolopas there is the specific gland, producing an odorous secret. With its help animals mark territory: for this purpose the hyracolopa rears on back legs, nestles by back to the stone or tree, and rubs against it.
Hyracolopas live in small herds numbering up to 15 - 30 animals. In herd there is no strictly expressed hierarchy, and its structure may strongly vary in due course: the herd may break up, or two herds mix up at one pasture and any time graze together. For night hyracolopas hide in bushes.
All species of this group of herbivores eat grassy plants, but can eat young branches of trees and bushes. The stomach of hyracolopas is complex, three-chambered and similar to stomach of ruminant animals. In forward chamber of stomach the colony of symbiotic protozoans, similar to those at ruminant animals, develops. They help animal to digest rough cellulose. The blind gut is poorly advanced.
All hyracolopas have kept a habit, characteristic for damans: animals leave dung always in the same place. Such behavior has the special role in their life: by smell of dung animals learn about the congeners, not seeing them at all. Some animals, living in one group, leave dung in same place.
Fast hyracolopa leads atypical for this genus way of life: it prefers plain habitats, living in savannas of Northern Africa. This animal reaches height about 60 cm at a shoulder. Wool of this animal is colored grayish-beige color with narrow and dense cross strips on body. On all legs there are white “stockings”.
Head of fast hyracolopa is colored brighter, than body: through eyes and forehead black “band” stretches, which ends wash out on neck; tip of muzzle is white. Such contrast colouring of head helps to warn congeners of danger: the disturbed animal highly lifts head, and even rears, looking over district. And colouring of its head becomes appreciable from afar, serving as an alarm signal for neighbours.
Due to strong rear legs fast hyracolopa can make long jumps, escaping from the enemy: up to six meters in length and two meters in height. Hoof-like claws are wide; therefore animal can walk on fenny ground and swims rather good. Frequently hyracolopas of this species escape from predators in water or in swamp.
The courtship season at all hyracolopas passes roughly: males gather small harems of females, jealously preserving them from each other. Threatening the opponent, they growl and show incisors, having opened mouth widely. If contenders do not concede each other, they can even fight, biting each other in back and nape, and striking impacts by forward legs.
Once a year at the female well advanced independent twin cubs are born. They are able to rise of legs at the first hour of life, and the daily cub does not lag behind mother. The young growth is colored not so bright, as adults: cubs don’t have “mask” and white sites on muzzle. They appear only at the age of about one year. At one and half year age young females become able to breeding. Males grow longer, and mature only up to age of two years.
Other species of hyracolopas live in mountains, and their area is limited to one or several ranges:
Rift hyracolopa (Hyracolopa riftica) lives in mountain woods of Central Africa, where it is the analogue of small antelopes like the duiker. Its growth at a shoulder reaches approximately 40 cm. Wool of this hyracolopa is colored dark brown, almost black color, and only tip of muzzle, throat and chest are white. In mountains where it lives, the weather may be rather cool, and ears of rift hyracolopa are covered from external side with short wool. This animal eats various kinds of vegetation: grass, ferns, tubers and bulbs of plants. It meets in herds numbering up to fifty adult animals.
Wooly-eared hyracolopa (Hyracolopa trichotis) lives even higher, than rift hyracolopa: on open hillsides with poor vegetation. This animal differs in dexterity and quickness: it can clamber on almost steep slopes. The wool of this species is colored brown, and only on throat of the adult male white wool grows. On back in the area of specific gland long wool grows. For protection against cold ears of this species are much shorter, than at relative species, and are covered with long wool from external side. This animal gathers in small groups and carefully marks borders of territory: fodder resources in mountains are poor, and the herd should have rather extensive territory.
Atlas hyracolopa (Hyracolopa atlassica) is the species of savannas and foothills of Atlas Mountains, inhabiting also rocky areas of south-west of Europe. It partly competes with flatland harelopes, eating rigid plants. The body is colored yellow, on back there is black longitudinal strip. On rear legs, and at separate individuals even on front ones, there are black cross strips on white background. Cheeks and throat are white.
Persian hyracolopa (Hyracolopa persica) inhabits mountains of Near East formed instead of Persian Gulf as a result of movement of Arabian lithospheric plate. The area of this species is partly crossed with area of rockloper (Lepotragus nivalis) from the order of hoofed lagomorphs (Ungulagomorpha). But both species do not compete with each other because of life in different habitats. Rockloper prefers dry slopes of mountains, and Persian hyracolopa prefers damper valleys overgrown with bushes. It frequently lives on hillsides overgrown by wood. This species lives in herds numbering 10 – 15 individuals. Colouring of Persian hyracolopa is spotty: general colouring is grey, on sides and groats small black spots are scattered. Forehead and back part of neck are also black. On internal side of forward and rear legs there are sites of white wool.
Alpine hyracolopa (Hyracolopa alpina) inhabits mountains of Southern Europe from Pyrenees to Balkan Mountains along the northern edge of Mediterranean swamps. It is the largest species of genus, reaching the size of domestic goat. It differs from other relatives in long wool with rich underfur that permits this animal to live in high mountains. General colouring of this animal is grey with black longitudinal strip on back and black spots on groats; legs are dark.

Plain hippotapirus (Hippotapirus terrensis)
Order: Odd-toed ungulates (Perissodactyla)
Family: Tapirs (Tapiridae)

Habitat: South America, Pampas and woodlands.

Picture by wovoka

Picture by Alexey Tatarinov

At the time, human activity led to the almost complete disappearance of the tapir family, but in the posthuman era, tapirs still managed to restore their numbers necessary for survival. Of the entire family, only the mountain tapir has persisted, having survived in remote parts of its former range. In Neocene, tapirs are a decaying group of mammals: only two tapir kinds have survived to that time. The first and most common kind is Tapirotherium genus, the elephant-like descendants of tapirs. The second kind is somewhat similar in appearance to some horse breeds of the human era, for which it was named hippotapirus (from Greek “ ἵππος” – horse). In the Neocene nature, it is a very rare and actually declining species – its populations are remote from each other and few in number, and there is almost no connection between them.
The animal’s body reaches 2.5-2.8 m in length; height at the withers is from 1.5 to 1.7 m. The tail is short: 15-20 cm long, in males with a small tuft at the tip. The weight of an adult is about 500-700 kg. Occasionally, large males reach 2 m at the withers, 3 m in length and gain up to a ton of weight, resembling huge draft horses. Such weight and size do not prevent such a male from reaching speeds of up to 25-30 km/h. Wool color ranges from light brown to dark brown. The hair on the neck, cheeks, and tips of the ears is lighter: it may be white, yellowish, or reddish. The coat is short and sparse. A short black mane grows on the neck, being longer in males. The length of the mane is an indicator of the animal’s health. Due to the high homozygosity of the genes, the coloration of adult individuals in each population is almost identical.
The coloration of the cubs represents a camouflage pattern: brown background with white or light yellow longitudinal stripes interspersed with white or yellow spots. In adult individuals of smaller hippotapirus populations living in the most arid regions of South America, light stripes may persist on the hind legs.
The hippotapirus has toes ending in hooves; there are 4 digits on the front legs and 3 digits on the hind legs, the largest of which is the middle one. The lateral digits almost do not touch the ground and take part in walking on marshy ground.
The neck and legs are long, almost like in horse. The animal is noticeably inferior in the lightness of a constitution of the horse of the human era, but much more graceful than its ancestor. Unlike tapirotherium, whose trunk has become similar to an elephant’s, hippotapirus has almost lost its proboscis with the transition to a predominantly herbal diet in the Pampas. It has become a device for cleaning inhaled air from dust, like in saiga.
Hippotapirus is unpretentious in food: it can eat both soft young and hard dry grass, it can eat young tree branches and dry shrubs, and it can even eat moss. However, if the hippotapirus has such an opportunity, it tries to settle near reservoirs, as it is very fond of sappy coastal grass and algae, as well as buds, foliage, young twigs, berries and fruits of riverine and lake-side shrubs and trees. Besides, hippotapirus loves wallowing and swimming very much. But it doesn't always have that opportunity.
Hippotapiruses sometimes have skirmishes with barocavias near reservoirs, but more often these two species of animals try not to come into conflict. Regardless of their habitat, hippotapiruses prefer to lead a nocturnal lifestyle, and during the day they sleep off somewhere in the thickets or, if possible, bask in ponds. Thus, this rare and vanishing animal avoids competition with other large herbivores of South America: deermaras and giant pacas, which are awake during the day and sleep at night.
Hippotapiruses can lead both a solitary lifestyle and live in small families. The head of the family is a male. But such a position among relatives can only be achieved by a male of large enough size, able to protect his females and cubs from large predators. Depending on the strength and fertility of the male, he can guard from two to five females, each of which gives birth to one cub. Twins are extremely rare, and the rate of reproduction of this species is very slow. In case of death of the male, leadership in the group passes to the older female. Females do not allow new males to approach them until they have raised offspring from the previous head of the family.
Communication in the family of these animals takes place via high-pitched calls and peculiar whistles. Every spring, males fight for the right to own as large a harem as possible. At this time, they bite each other and strike the opponent with their front hooves.
Mating takes place in April-May and is accompanied by a certain mating ritual. Agitated hippotapiruses utter whistling sounds, circle around each other, nibble slightly their partner’s ears and sides. Pregnancy lasts 385-407 days; females bring 1 cub weighing 10-12 kg. In the first days of life, the cub does not leave the hidden shelter, and the mother stays close to it. However, it develops quickly and after five days it begins to accompany the mother in search of food. The camouflage color fades at the age of 5-6 months, the cub weans off milk at the age of 5 months, and becomes completely independent at the age of one year. At the age of 18-20 months, it already reaches adult size, and by the age of 2 and a half years, the young animal reaches sexual maturity. The average life expectancy of lowland hippopotapiruses is 25-30 years.
The main predator of hippotapirus is the tigrine raptor cat, but even it tries not to mess with large males. Hippotapiruses defend themselves aggressively, using their front and hind hooves, and often use their strong teeth. Hunting herons, akatous, and uekubus can also attack cubs, but they try to attack only straggling cubs, as they are afraid of their parents’ hooves.
Deermaras and hippotapiruses often resort to cooperation. While the hippotapiruses sleep during the day, the deermaras grazing nearby are awake and, in case of danger, warn the sensitively sleeping hippotapiruses with their behavior. Conversely, hippotapiruses grazing at night can warn of the danger of deermaras sleeping at night. Given the belligerence of male hippotapiruses, deermaras receive real protection from predators from such a neighborhood. Joint feeding takes place only in the morning and evening, when both species are awake. Such cooperation between the deermara and hippotapirus is similar to the cooperation of harelope and shurga in Siberia. Nevertheless, it is the proximity of these two herbivores that leads to a gradual decrease in the number of hippotapiruses.

Tapiroid (Tapirocephalus velox)
Order: Even-toed ungulates (Artiodactyla)
Family: Trunk boars (Proboscichoeridae)
Habitat: bush thrickets of Southern Europe.

During global changes in ecosystems unspecialized species able to live in various conditions and to use for food plenty of forage kinds survive basically. During change of Holocene by Neocene among few survived hoofed mammals pigs were such universals and champions in survival. After ice age and extinction of big number of European hoofed mammals pigs were among animals successfully existed in narrow zone of vegetation clutched between glacier of kilometer thickness and heated salty desert of Mediterranean. When glacier had receded pigs among the first wave of migrants had started to develop free territories and later migrants from Asia and Africa were compelled to compete with specialized descendants of wild boar (Sus scrofa).
Boar family had becomed prospering group: among them special family of trunk boars has appeared at which representatives muzzle had turned to short proboscis. This adaptation has given appreciable advantages to its owners having expanded opportunities of food getting. In family even such species started to develop sea coasts had appeared – it is huge flattooth (Belonoporcus dolichocephalus).
As against to massive flattooth tapiroid is terrestrial animal. Length of body of adult animal is about 2 meters, height at a shoulder is 1.7 m. The constitution indicates fast runner in it: at this animal there are muscled body and long legs. It can accelerate momentum up to 40 kms per hour at the long distance and at short time accelerate up to 60 kms per hour. On every leg of tapiroid there are two large hoofs: characteristic for pigs hoofs on 2-nd and 5-th toes are underdeveloped and sometimes are absent at all. In appearance of tapiroid there is a feature making it similar to South-American tapir: massive head with long proboscis. With the help of flexible proboscis tapiroid can browse leaves and young branches of bushes containing basic part of its ration. Neck of tapiroid is rather short but due to proboscis it does not have inconveniences in daily life. Body of animal is covered with rigid thin wool and on back skin is very thick – it is its protection against predators. On tips of long ears there are hairy brushes raising sensory acuity. Eyes at tapiroid are small and sight is rather weak. But sense of smell at it is very keen: due to presence of proboscis the olfactory surface of nasal cavity is strongly increased.
Wool of tapiroid is colored brownish-yellow with dark longitudinal strips on back (such colouring is characteristic for boar piglets). Due to inhabiting in bush thickets this juvenile attribute became very useful to survival.
In mouth of tapiroid sharp tusks directed forward and in sides grow. At males they reach significant size. Males of this species apply tusks to duels, establishing hierarchy or combating for female. During fight opponents simply cling each other by one tusk and try to tumble down the contender by movement of head and body pressure. Dangerous wounds this way are completely excluded though at old males tusks sometimes break. At the predator attack animal uses tusks as thrust weapon causing to predator deep wounds similar to dabber ones.
Tapiroids live in family groups of 15 - 20 uneven-age animals (young growth of the current year makes up about half of group) under the leading of large male. Each group lives in the certain territory on which goes adhering about constant routes. During movement herd treads and eats young growth of bushes, therefore in habitat of these animals through continuous bush thickets wide tracks pass. And the more herd living in certain territory, the wider tracks left by it are. In tracks graminoids grow basically changing by othergrasses at the edge of tracks. It gives food to many other bush inhabitants.
Tapiroids eat leaves and young sprouts of bushes, soft grasses and mushrooms. Because of short neck they can not graze on grass and dig out roots and tubers as their ancestors, but in bushes they find a lot of suitable forage.
At the watering place animals are cautious: they can reach water only having bent forward legs, therefore any part of family group stands on the alert while other animals drink water.
Cubs of tapiroids are born in spring when it is a lot of forage and water. Female gives rise to two - three cubs covered with short wool. By colouring young growth is similar to adult animals, colouring is only brighter appreciably and more contrast. Cub rising occurs almost simultaneously at all females of family group. Cubs spend first days in shelter among bushes, yet they will get stronger enough to move after adult animals. On 3-rd - 4-th day they abandon shelter and herd continues movement.
Females can already rise posterity at two-year-old age, and males though become mature almost simultaneously with females, receive chance to pairing only at the age of four years having developed to full might. Life expectancy at this species is about 25 years.

Kelpie (Paludiporcus kelpi)
Order: Artiodactyls (Artiodactyla)
Family: Trunk boars (Proboscichoeridae)

Habitat: Europe, river banks, lake shores and swamp edges in the forest area.
Neocene pigs are a very successful group of animals. They took advantage of the anthropogenic crisis of the end of Holocene and managed to occupy the ecological niches of large ungulates and proboscids of Eurasia. It was only in Siberia that they were outpaced by obdas, the hoofed lagomorphs. Trunk boars of Neocene are descendants of the wild boar and represent one of the characteristic groups of animals of various Eurasian landscapes. They are found from the Siberian taiga to the arid maquis of Southern Europe. One of these strange animals is the kelpie, which has occupied the wetland habitats of continental Europe north of the Alps.
The body length of an adult kelpie is up to 3 m, the height at the withers is 150 cm, and the weight is about 2 tons. It is a runty, long-bodied animal, partly resembling the fossil Neogene marsh rhinoceroses. The animal’s skin is thick and covered with rigid brown wool. In the west of the range, a lighter-colored and smaller morph is found with chains of dark spots stretching along the back – the remnants of juvenile coloration. Unlike its close relative, the flattooth, kelpie has tusks bent down and a trunk, the base of which is capable of inflating into a resonator bubble.
The hooves are wide, able to move apart, and there is a thick skin membrane between them – thanks to this adaptation, kelpie easily roams through the bogs and can swim. Outwardly, it resembles a cross between a deinotherium and a buffalo – it is a powerful, heavy and short-tempered beast. Most often, kelpie grazes on the riverbanks and lake shores, or in swamps, feeding on reeds, amphibious and aquatic vegetation. With the help of its tusks, it digs out roots and bulbs from the soil. In winter, kelpie has difficulty getting food; in the north and east of its range, the distribution of this species is limited to areas where rivers freeze only for a very short time. In winter, in cold areas, kelpie breaks the ice, if it is not too thick, and digs the frozen soil with its tusks. At this time, a significant part of its diet consists of coarser food – dried plants, branches and bark of trees and shrubs. The tusks and proboscis help it to shovel the snow. It partly competes with nozdrokhs and woolly boars, but in general it feeds on different plants, including coarser ones. This beast is capable of eating some poisonous marsh plants.
Kelpies live in small family groups – a male, a female and cubs of the last two years, or bachelor herds of 5-6 heads. This reduces competition for resources and helps defend against enemies.
The kelpie mating season takes place in July and August, when the animals are well-fed and in the best physical condition. Males compete for the attention of females by blowing into their trunks and pushing with their sides and shoulders. When they vocalize, the base of the trunk is inflated like a large bladder of skin. Tusks are not used during the courtship duels. Pregnancy lasts 9 months, after which the female gives birth to 1-2 striped cubs. They feed on milk for 2-3 months, after which they pass to adult food. Puberty comes at the age of 3 years, and shortly before that, the young animal is expelled from its family. Such adolescents form bachelor groups, forced to seek and conquer territories for their life. Most often, kelpie families are formed from members of these or competing groups. The first participation in reproduction in males is possible since the age of 4-5 years due to the intense competition with their relatives. Life expectancy is up to 35 years. The natural enemies of this species are berls and large cats, small cubs are occasionally hunted by eagleravens and spinywolves.

Nozdrokh (Probosciaper mammutoides)
Order: Even-toed ungulates (Artiodactyla)
Family: Trunk boars (Proboscichoeridae)
Habitat: woods of Central and Eastern Europe up to Ural.

Picture by Leonard Popov

In Russian annals by the word “nozdrokh” any large animal, most likely mammoth meant, whose frozen carcasses occasionally had been founded by people, derivating every possible legends. Therefore the large animal of Neocene epoch, rather reminiscent by the constitution proboscides missed a long time ago, is named so.
The extinction of large animals caused by chasing from the side of people, destruction of places of inhabiting and natural accidents, has released a way for evolution of groups of animals, not numerous and not variable before it, having allowed them to realize to the full the evolutionary potential. Among such “lucky beggars” of Neocene epoch non-ruminant artiodactyl mammals appeared. In North America dominant large animals peccasons from peccary family (Tayassuidae) appeared. But in Old World pigs (Suidae) have reached of the big success: among them ecological analogues of such various hoofed mammals, as horses, bulls, hippopotamuses, tapirs, and even proboscides have appeared.
Nozdrokh, the inhabitant of woods of Europe, is a huge descendant of the wild boar, whose growth at a shoulder reaches 2 meters. It differs in heavy addition and thick legs. Head of nozdrokh is rather big. Well-known tusks, the main weapon of boar, at this species had started to increase, resembling tusks of mammoth: they are bent upwards by half rings. It is convenient to rake by such tusks a wood litter in searches of roots and acorns. And in winter with the help of tusks nozdrokh easily scatters snow, reaching up to a last year's grass. Jaws of animal are rather short and strong, in case of necessity it can feed even with young branches of trees and bark which it peels out by tusks. As against to proboscides, at nozdrokhs the “conveyor” of replacing teeth is not formed.
Snout characteristic for pigs at ancestors of nozdrokh started to grow in length, and became short, but flexible high-grade trunk. Due to it the animal can lift even a small acorn from the ground. Inside the trunk there are some pairs of plicas of epithelium. They serve as original additional “vocal chords”, expanding a spectrum of sounds uttering by the nozdrokh - from the trumpet roar similar to elephant’s voice, up to silent chirp and squeak.
Ears of nozdrokh are short – it lives in rather cool climate, and problem of overheat do not arise at it. The animal is covered with a shaggy rough wool of brown color. To winter at it the rich underfur grows, permitting to endure rigorous frosts.
In ecosystem of woods of Europe nozdrokh partly occupies an ecological niche of large wood hoofed mammals – aurochs and urus. It mainly eats leaves of trees and bushes, adding to them fern rhizomes, tubers and bulbs of various plants. In summer nozdrokhs willingly feed near reservoirs, pulling out by tusks whole bushes of reed. Near reservoirs nozdrokhs spend the hottest days of summer. Due to wide feet they easily cross bogs, and frequently come to bogs to wallow in dirt and to cool.
This animal keeps in small herds (up to 5 - 6 animals) under the leading of adult male. It does not tolerate competitors, and expels young males from herd when they become independent (at the age of approximately 2 years). Except for him, in herd there are 2 - 3 sexual matured females and other individuals are young growth. Young males expelled from family groups, form barchelor groups of 2 - 4 animals. They more tolerantly concern to each other until will get own harem. Animals in group constantly communicate with each other with the help of various sound signals – this way of communication is especially good in rich wood where animals frequently lose sight of each other.
Female every time gives rise to one cub once per 2 years. It feeds exclusively with her milk, but in case of danger can expect for protection of any of females of herd. The cub is born rather weak. It is covered with longitudinal strips – this is the type of juvenile colouring, characteristic for pigs. First two days of its life all herd stays at the place, preserving it and expecting while it will start to walk and will get stronger enough. Gradually strips on its back become dimmer and disappear to bi-monthly age. Sexual maturity comes at the age of approximately 20 months, and life expectancy may account about 40 years.

Mass extinction of the majority of groups of hoofed mammals at the boundary of Holocene and Neocene became mainly the result of human activity. Only most unpretentious and ecologically plastic species have managed to survive, having kept as small populations. After disappearance of mankind they have started to fill in released ecological niches.
The geography of planet in Neocene epoch has changed, though it has remained rather recognizeable. From Africa along the “seam” of Great Rift Valley the large land site had “broken away” – Zinj Land. And here one of species of hoofed mammals, river hog (or bush pig) (Potamochoerus porcus), had turned to the interesting creature similar to bulls of Holocene epoch.
The river hog had small bone knobs before eyes. Evolution had picked up and had developed this “idea”, and the descendant of river hog, porceratella, had acquired a pair of sharp horns directed forward and a little in sides. It is interesting, that at the continent descendants of bush pigs either have lost rudiments of horns completely or have acquired one large unpaired horn similar to horn of brontotheres. All these animals belong to the separate family of horned hogs (Porceratidae).
Osseous horns of porceratella are precisely separated from each other, and resemble horns of bovids. They are filled with friable bone tissue lowering their weight, but their top layer is enough strong and they could be used as the tournament weapon, and for protection against predators.
Externally porceratella resembles small cow with back curved upwards. Height of animal at a shoulder is about one and half meters, weight of the male is about 500 kg, female up to 400 kg. The wool is short, rather thin, brightly colored: back is rusty-red, sides are white and the bottom part of body is black. The area under tail is covered with white wool. Behind on hips between sites of white and red color there passes a black strip. Wool on throat is also black. Around of eyes there are small white “glasses” (sometimes they may be absent), on tips of ears there are rich black hairy brushes. The tail is covered with rich white wool, its tip is black.
The nose has turned to small mobile proboscis, shorter, than at saiga or tapir. Characteristic for pigs ossifications in snout are reduced and the animal can not dig out by it something from the ground, but can pick up edible parts of plants. Due to proboscis the animal can utter various blares. Also the big surface of nasal ducts promotes development of sharp sense of smell. Sight plays smaller role in life of porceratella: the bases of horns form protective “eyebrows” which prevent it to see object that is directly ahead: to make it, the animal raises head a little.
On the top jaw there are sharp tusks directed forward and in sides. With their help the animal digs ground in searches of food. In the case necessity porceratella can put deep wounds by these tusks.
Hoofs can move apart, due to what porceratella is able to walk along fenny marsh ground. Besides it does not avoid water: it willingly swims, feeds with water plants, and searches in water for protection against ground predators.
Porceratella keeps in herds numbering 15 - 20 ones. Over the herd is predominated by the female, and other members of herd are also females. Males keep in herd only while depend on mother. The leader female expels become adult males. Males form barchelor groups of 5 - 6 animals in which the not strict hierarchy is observed. But in season of pairing (in the middle of rain season) they become aggressive, and can even kill each other in tournament fights.
The posterity is born in the beginning of dry season, when there is no danger of flooding of forests. In litter there are usually two cubs, at young females only one cub is born. At the age of approximately three months at young animal horns start to grow, and half year old males are already compelled to lead independent life. They completely develop and become able to breeding at the age of 2 – 2.5 years.

Artiodactyl mammals in Holocene turned to favourite objects of people hunting. Human activity has resulted to strong reducing of the number of various gregarious animals (mainly bovids), and the majority of species of these animals had disappeared. Only few relic species kept in Asia and South Africa. The place of small swift-footed antelopes in Neocene was occupied by various animals of new groups: harelopes of lagomorph group and hyracolopas, cursorial descendants of hyraxes. And the place of larger herbivores – rhinoceroses and buffaloes – representatives of other groups of mammals, various descendants of damans, had shared. At the East-African subcontinent named Zinj Land, large descendants of hyraxes are represented only by one semi-aquatic species. At the subcontinent the large descendants of pigs occupied ecological niches of ruminant animals had appeared. One of the most widespread species is bikifaru, large species of horned descendants of pigs.
This animal is larger relative of porceratella, which leads migrating way of life and differs in rather graceful constitution. This is stout cow-sized animal, also similar to cows by proportions. At the short distance bikifaru can accelerate momentum up to 50 kms per hour, but it can not support such rate for a long time. Hoofs of this animal can move apart - bikifaru frequently feed on juicy marsh vegetation at the fenny ground. Also this animal is not afraid of water and is able to swim well.
Wool of animal, living in hot climate, is rough, short, sandy-yellow colored. On back and hips there are some dim darker spots. The tail of animal is long – with its help grazing bikifaru drives off blood-sucking insects. On tail there is big black-and-white brush of long hair. Using it the animal submits signals to congeners: the tail with hairy brush lifted upwards, well seen from apart, is the alarm signal, clear not only for bikifarus, but also to their neighbours.
Neck is moderately long; head is rather small. But the structure of head of animal has determined its name. “Kifaru” in suachili means “rhinoceros”, and “bi …” means “double” in Greek. On head of this animal not horns, as at porceratella, but two longitudinal bone crests grow. These outgrowths are too thin to be used for combat, and serve more for demonstration. Also they help to move apart prickly branches of bushes among which bikifaru lives and feeds, and protect eyes from damages. Crests are semicircular; on nape they stick back like two horns. These crests are covered with thick rough skin and short wool, and frequently grow very large – at old males the size of crests can be almost equal to the seen sideview of head. Crests of males have a border of black wool on edge, and due to it are appreciable from apart. At females on crests there are only separate black spots, and at young animals colouring of crests is the same, as at all body. The width of black border depends on level of testosterone, and this feature helps males to estimate force of each other, not entering combat. Females also prefer to couple to males, at which there is more of black wool on crests. Also at males at edges of crests knobby osseous outgrowths develop. At males the small tusks, inflexed and turned in sides, also are advanced. This is the weapon for demonstration, but the defending animal can strike a predator by lateral movement of head. At females tusks are smaller and are visible only when the animal opens mouth.
Lips of bikifaru are mobile, and the muzzle is extended to small proboscis. Inflating proboscis and contracting nostrils, animal can utter various sounds. In bushes where visibility can be very bad, this animal communicates with congeners almost exclusively with the help of sounds.
Bikifaru is strict vegetarian; it eats leaves of bushes and branches of young trees. Jaws of this animal are rather weak; therefore the animal does not eat rigid grass. Due to the structure of hoofs bikifaru can graze in bogs, where it eats leaves of huge grasses and gathers floating plants from surface of water.
This species lives the herds numbering up to 20 – 30 adult animals. The herd is ruled by large male which constantly keeps up observance of hierarchy. Between males there is rather rigid struggle for leadership: the dominant male can couple to the majority of females of herd. Males standing a rank below the leader also have opportunity to have posterity, especially in big herd. The old animals, not able to support by force the place in hierarchy, quickly fall to the bottom step of hierarchy of herd and only the young animals recently becoming independent can be lower than they are. Old males usually keep in back part of herd, and fall victims of predators the first.
Seasonal prevalence in breeding of bikifaru is not present. The female ready to pairing involves at once many males which arrange combat for the right to couple with her. Pregnancy lasts about eight months and is finished by birth of one or two cubs (twins are born in third of cases). The cub is born advanced and can walk at once. It differs from adults in absence of longitudinal crests on muzzle. Its colouring is brighter, rather than at adults – on sides of young animal there are black spots, merging to faltering longitudinal strips. At growing animal they grow pale and vanish on the most part of body. At the animals living in richer bushes and light forests in south of area, at the border of rainforests, spots are kept to all life. These animals, larger than northern ones, are classified as the subspecies Dilophoporcula rhinocerotoides maculata.

Brontothere hornhog (Porceras brontotherioides)
Order: Even-toed ungulates (Artiodactyla)
Family: Horned hogs (Porceratidae)
Habitat: savannas and light forests of Southern Africa, dry sites, foothills.

Presence of small bone outgrowths before eyes at bush pigs (Potamochoerus porcus) looks insignificant attribute at first sight. But evolution had picked up this attribute, and it has received the development at descendants of these animals: at them on head large bone outgrowths of various shapes have appeared. So on life arena the family of non-ruminant artiodactyls, horned hogs (Porceratidae), has appeared. At the representatives of this family living at the Eastern African microcontinent, there is the pair of horns a little bit similar to horns of bovids. And at inhabitants of continental Africa on the head mainly unpaired outgrowths were developed, making these animals little bit similar to rhinoceroses extinct at the end of Holocene and brontotheres dyed out to end of Paleogene. In continental Africa these animals are spreaded mainly to the south from zone of tropical woods, in damp savanna and mountains of Southern Africa.
The brontothere hornhog is one of the most typical representatives of the family, widely widespread in rather dry habitats. By constitution it is similar to bull (growth at a shoulder is up to one and half meters), but its head strikingly differs from bull’s one. It is larger, with rudimentary proboscis developed from characteristic snout of pigs. The most remarkable feature is the presence of huge osseous horn. It is formed by pulled and grown together pair bone knobs characteristic for ancestor. The horn rises perpendicularly to forehead; it is expanded in sides and partly doubled at top. It is rather demonstration, than fighting weapon. But with the help of strong cervical muscles the brontothere hornhog can hook by horn the attacking predator and reject it aside. During intraspecific tournaments males of this species butt, having inclined a head aside, and resting by bases of horns. But usually they avoid direct fight, and only show horns to each other. At females horns are shorter, than at males.
Wool of this animal is very short. On chin hair are a little bit lengthened. The horn is hairless, covered with cornificate skin. The basic colouring of body is light grey, only on nape lengthened black hair form similarity of mane, and on long tail there is black hairy brush.
In mouth there are two long incisors similar to teeth of fossil rhinoceros Chilotherium: animal uses them to dig out roots and tubers. Also during courtship duels the animal can put to the opponent stings. Jaws of brontothere hornhog are long and rather weak. The basic food of animal includes young grass and leaves of bushes.
The brontothere hornhog is able to run quickly and long – at it legs are rather long. In this connection hoofs of this animal are small – this way friction against the ground is less. But it imposes the certain difficulties: the animal is compelled to avoid fenny areas, and comes into water only in case of emergency. Animals avoid places where there are flooding. Differing in ability to predict weather, they leave lowland areas to which flooding may threaten, and migrate to foothills. At this time separate family groups may unite, and then between males fights happen.
This species keep in small herds (up to ten adult animals), each of which represents a harem of one male. Animals communicate with each other by means of various sounds uttering with the help of short proboscis (at this moment it is slightly puffed). The young growth keeps with parents before independence then males are expelled by the leader, and females – by adult females. Seasonal prevalence in breeding is expressed poorly, but the majority of cubs is born in the beginning of rain season. In litter there is always one cub.

Ngoubou (Porceras ngubu)
Order: Artiodactyls (Artiodactyla)
Family: Horned hogs (Porceratidae)

Habitat: Kalahari, arid areas in southern Africa.
Sub-Saharan Africa harbors many large herbivores. The main groups of these animals are the flathorns, large descendants of the hyraxes, as well as horned hogs, descended from the bushpigs (Potamochoerus) of the human epoch. In Africa of the Neocene epoch, various horned hogs occupy the ecological niche of large herbivores – buffaloes and partly rhinoceroses. Many horned hog species, such as the brontothere hornhog (Porceras brontotherioides) and bullhog (Buchoerus crassoceras), inhabit more or less moist savannahs with good biological productivity. More arid areas of southern Africa harbor ngoubou, one more horned hog species.
Living conditions in the Kalahari, in the main ngoubou habitats, have not become much more favorable compared to the Holocene epoch. Of course, it rains more often in these places, but the Kalahari still strongly resembles the savannahs and semi-deserts on the African edge of the Mediterranean lowland. Ngoubou is one of the few large herbivores capable of living in this place.
Ngoubou is a large ungulate species: the height of an adult individual at the withers is 1.25 m, and the body length is about 2.5 m. The animal’s physique is very massive: in appearance, ngoubou resembles a cross between a pony and a tapir. On the large head of the animal, there is a single horn, massive at the base and expanding laterally at the end. It is not a weapon in intraspecific conflicts: it cannot take the punches of fighting animals and is suitable only for display. In mature males, the horn is expanded at the tip, slightly resembling the outline of a whale’s flukes. The female’s horn is smaller, and the female itself is also smaller than the male. If necessary, the female is able to drive away small predators from the cubs, and even pick them up with her horn and throw them in the air. Ngoubou’s main defensive weapon is ten-centimeter tusks, pointing forward and slightly upward. With their help, the males find out the relationship by hitting the thick skin on each other’s shoulders.
The animal’s hair is sparse and light gray in color – such coloration saves the animal from the heat. Sometimes the general coloration of the animal is almost white or yellowish. Only on the legs of animals there are thin intermittent transverse stripes of black color. The horn is covered with rough gray hairless skin. There is a tuft of long black hair at the tip of the tail.
Ngoubou feeds on coarse fibrous vegetation, which is digested in a three-chambered stomach. The first section of the stomach is a “fermentation tank”, the second section is muscular, with corneous outgrowths on its walls, and the third one is glandular. The animal does not chew the rumen, and the fermented mass of plants is additionally grinded by the walls of the second part of the stomach. Ngoubou is very hardy: it drinks only during the rainy season, getting water from food during droughts. If necessary, ngoubou can eat the stems of mildly poisonous succulent milkweeds and prickly aloe leaves. By the beginning of the dry season, fat is stocked on the animal’s back and shoulders, forming a hump.
This animal lives in family groups, including one male, 3-4 females and young. The animals constantly communicate via sound signals. The animal’s voice is a mix of a roar and a grunt, and the alarm signal is a growling sound.
The seasonality of reproduction is clearly expressed and is associated with rains. Rutting takes place at the end of the rain season. At this time, males are especially eager to display their horns to their rivals, shaking their heads, raising their tails and emitting the smell of musk. If displays are not enough, they push each other with their shoulders and chests, and poke each other with their tusks, but never inflict dangerous wounds on an opponent. At the beginning of the next wet season, the female gives birth to 2-3 cubs. After birth, the cubs are darker than the parents and the longitudinal stripes cover the entire body at them. At the age of 3 months, the cubs switch to adult food, and one-year-old animals are driven out of the group by adult animals. Up to the age of three, young animals form mixed herds, but then the females join the harems of adult males and approximately the similar age groups of males remain. Young bachelor males begin to compete for females since the age of about five years, although they mature about a year earlier.
The life expectancy of ngoubou is up to 35 years.

Bullhog (Buchoerus crassoceras)
Order: Even-toed ungulates (Artiodactyla)
Family: Horned hogs (Porceratidae)
Habitat: savannas and light forests of Southern Africa, damp sites near to rivers and bogs.

When during evolution process in nature a “successful” variation of live beings appears, on its basis related forms adapted to different conditions of inhabiting at once start to evolve. In Southern Africa at the basis of the common ancestor different species belonging to new Neocenic family of horned hogs were evolved. These animals have partly replaced large ruminant artiodactyl animals, not sustained chasing from the side of people and destruction of habitats during a catastrophic congelation. Hornhogs became analogues of buffaloes, large antelopes, and partly even rhinoceroses. Bullhog is the largest representative of family.
This species of mammals differs from brontothere hornhog by more powerful addition: the animal is very similar to large buffalo. The highest point of the body is at shoulders, back is a little bit sloping. Wool is short, pale-yellow, and lighter on stomach. On cheekbones wool forms black “whiskers” especially obviously expressed at males. Legs, partly shoulders and groats of animal are covered with short horizontal strips of rusty wool. Tail is long, with hairy brush on the tip.
The most characteristic attribute of animals of horned hog family is the horns of various shapes developing in middle part of head. At bullhog, despite of the name, horn it is completely not similar to bull horns: it is wide and flat, reminiscenting somewhat the horn of living in North-African savannas flathorn (Platyceratherium foetidus), huge animal from order of damans (Procaviiformes). It is wide, covered with cornificate skin, and concave in middle part. The horn of bullhog is mainly the tournament weapon, rather than fighting one: in courtship season between males of this species there is a force struggle by necks (muscles of neck are very strong). Horns serve as protective “helmet”: they are formed by thick layer of bone tissue with a minimum quantity of cavities. But also this horn may be used as the weapon: to attacking predator protecting bullhog puts ramming impact by head. The horn protects eyes from casual wounds, therefore, having “hooked” predator by flat horn, bullhog can lift it in air, and then simply strike a predator against tree or throw off far.
As against the relative, the brontothere hornhog, bullhog prefers sites which may be flooded. This animal willingly bathes and wallows in dirt, and also searches near to reservoirs for significant part of food – soft vegetation. In this connection at bullhog the wide hoofs able to move apart partly, when the animal grazes at the bog, were developed. Also the animal is able to swim very well, and easily crosses even wide rivers and lakes.
Bullhogs keep in small harems: one male and 3 - 4 females with cubs of the age till one year. Such harem occupies the certain territory along the river bank, or in bogs, and does not leave it even at flooding. Except for such families, there are single males living at the narrow border lands between possessions of family males. Usually they are either very old males expelled by young contenders from own groups, or young males, yet not having own harem. In courtship season young animals challenge family males, and between them there are skirmishes.
Once a year the female gives rise to 1 – 2 cubs. They differ from adults by darker colouring in which there are more strips (they stretch even on back and sides). The female carefully preserves them against predators, and easily may attack any animal if it will seem that the invader represents threat for the cub. The young growth is fed with milk till four months, and then completely passes to vegetative forage. One-year-old youngsters abandon herd: shortly before birth of the new cub the female starts to show aggression to them.
Sexual maturity comes at the age of about 3 years, life expectancy may account till 40 years.

Hyena-like deinaper (Deinaper crocutoides)
Order: Even-toed ungulates (Artiodactyla)
Family: Predatory boars (Carnoporcidae)
Habitat: grass plains and bush thickets of Central and East Asia.

In Paleogene and early Neogene among characteristic inhabitants of open spaces of Eurasia and North America there were entelodons (Entelodontidae) – family of non-ruminant artiodactyls, related to pigs. By structure of teeth, they were omnivores in which diet meat took an essential place. After epoch of mass extinction when many ecological niches appeared free, pigs have taken advantage of a situation, and have taken a vacant place of scavengers. So at plains and in bush of Asia the family of Predatory boars partly occupied a place of hyaenas and bears had appeared.
The typical representative of this family is deinaper (“deino-“ means “terrible”, and “aper” – the boar), the largest species in family. An ancestor of this animal was wild boar (Sus scrofa), the species widely widespread in Eurasia and have successfully survived the period of anthropogenous pressure. The important place in diet of boar was occupied with food of animal origin. One of the evolutionary lines, originated from this species, has gone to the way of adaptation to searching and eating larger amount of food of animal origin. Gradually these animals have turned to scavengers, and even had become able to attack cubs of other animals.
Deinaper is an animal of massive constitution, its growth at a shoulder is about 0.8 m and weight is up to 140 kg. By constitution it is similar to the spotted hyena: at it there is large head on mobile neck. Its body is covered with shaggy rough wool; to winter rich underfur grows. In connection with unusual for hoofed mammals way of life at it spotty colouring developed – strips characteristic for boar juvenile colouring, break up to separate spots. It even more strengthens similarity of deinaper with hyenas. Legs of animal are rather long, adapted to fast running to the big distances. Because of long legs the body seems a little bit short.
Jaw are short and high, able to crush bones. There are large sharp tusks jutting out up and in sides. They are used as the weapon in tournament fights, but in case of need deinaper can use them against predators.
The appearance of muzzle of deinaper is characteristic for pigs. Sense of smell is sharp - with its help animal searches for carrion and finds small animals. Deinaper is aggressive: it can drive away medium-sized predators from catch, threatening them with tusks and making sharp attacks on aside a predator. As this animal lives small groups (up to 4 – 6 adult animals), not any predator can defend the right to the catch in the face of several strong and aggressively adjusted animals.
The group of deinapers supervises extensive territory on which there are some shelters. Borders of territory are marked by heaps of manure, and constantly renewed. In shelters animals spend hottest time of day, becoming more active in the morning and in the evening when the majority of predators hunts. If won over catch at predators does not suffice, deinapers can hunt in the afternoon. Then they attack small animals having a rest in a shadow.
Once per year the female brings posterity: up to 5 – 6 cubs. Feeding female does not take part in hunting, protecting posterity. The only thing, that it presumes to herself – to catch any tiny casual catch like reptiles and rodents. But males and females without cubs after successful hunting necessarily belch for feeding female pieces of meat. Newborn cubs are weak and helpless: they start to stand only at the age of one week, and pass to feeding by meat only at bi-monthly age. Approximately at the age of three months young animals leave lair, and lead nomadic life with parental group. Only at the second year of life the young female can give posterity the first time. And the young male can really apply for domination in clan only since the fourth year of life. Up to this time it leads life of the lonely hunter in boundary territories, gaining strength and experience to challenge once in winter to any old leader of clan and to take his place.

(This animal is discovered in common: by Tenek, the participant of forum (she has stated the assumption of existence of the present animal in Neocenic fauna), and by Arseny Zolotnikov (he created initial sketch of the present animal))

Varaha (Barodeinaper waraha)
Order: Even-toed ungulates (Artiodactyla)
Family: Predatory boars (Carnoporcidae)

Habitat: Southern and South-East Asia, Hindustan; forests of various types and bush.

Picture by Alexander Smyslov

Pig family is among champions on survival. These animals, easily growing wild and easily adapting to various conditions, used in full degree possibilities on development of new habitats opened after human disappearance. In due course of evolution the North of Eurasia was occupied by trunk boars, and in Africa and on Zinj Land horned forms of pigs evolved. For Asia the special family of predatory boars is endemic – it is a peculiar attempt of pigs to become carnivores as entelodons did in Tertiary. In temperate areas of Asia the hyena-like deinaper (Deinaper crocutoides) is widespread – it is the carnivorous species being ecological analog of hyenas. To the south of the Himalayas it is replaced by varaha, the species of close genus.
Compared to deinaper, varaha is larger species adapted for life in rainforest. Its growth at a shoulder is about one and a half meters, body length to 2 meters, weight is about 400 kg. Varaha has powerful jaws and extended wedge-shaped muzzle which ended with the small snout. Skull bones are quite massive – in case of need varaha strikes to competitors blows with a forehead. Tusks of animal are well developed and inflexed, but are turned sideways only a little, therefore they don’t hamper the movement of the animal through dense underbrush. The main purpose of tusks is to be the duel weapon. During courtship season males hook the contender by tusks and try to tumble down each other, using strong muscles of neck and shoulders. Wide ears are used for heatreturn though in daytime heat varaha more often simply searches for a reservoir where it has a rest during the hottest time of day. On neck and shoulders of animal the standing bristly mane is developed similar to mane of wild horses and creating the illusion of larger size, than is in fact.
Skin on neck and shoulders of varaha is very thick and strong – even a large predator hardly bites through it. For attaching of the muscles supporting the head, at this animal spinous processes on cervical and chest vertebrae are well developed. Because of it the back of an animal is sloping a little.
Legs of varaha are short, but strong, with two well developed hooves on 3rd and 4th toes. The 2nd and 5th toes are underdeveloped, and their hooves are appreciable as two small bumps on each side of fore- and hind legs of animal.
Unlike the spotty northern relative, varaha has longitudinally striped coloring. The main background of coloring is reddish-brown, on the back narrow longitudinal strips of black color stretch. Coloring of the top part of head of this animal sharply contrasts with body color – it is black with two large white spots under eyes. This coloring has obvious warning character – varaha has aggressive temper and can easily rush on the competitor, driving it away from food. Lower part of head is brown, and mane is black.
Varaha eats mainly food of animal origin. This animal often eats carrion and searches for it, using keen sense of smell. Also varaha attacks small animals, which are trampled or biten to death, and then eats them entirely. If necessary, varaha can win away prey at predators – it attacks and tries to bite a predator or to hook it by tusks. Due to skin “armour” and strong skull it easily endures blows of predators and more often defeats them, forcing them out from prey or to wait, while varaha will be sated. Bumps on teeth of animal have sharp tops and cutting edges.
Varaha female gives birth once a year to three cubs. Piglets spend first two weeks of life in den built in secluded place, and then leave it and lead nomadic life, keeping near mother. At the age of about 5 months between them the competition becomes aggravated and they start to lead independent life. The sexual maturity at them comes at the age of 2 years, but males receive real possibility to take part in reproduction not earlier than at the age of 4 years. Life expectancy reaches 30 years.

Mantahungal (Barodeinaper mantahungal)
Order: Artiodactyls (Artiodactyla)
Family: Predatory boars (Carnoporcidae)

Habitat: Southern and continental Southeast Asia, nearby islands.
Among the entire order of artiodactyls, pigs and similarly looking peccaries are among the most atypical herbivores, since they are omnivorous, like the wild boar (Sus scrofa), the most typical representative of the group. Most pigs in the human era belonged to the large animal species. This life strategy led to the fact that they easily survived the extinction of humans and changes in the biosphere, and during the recovery period they began to fill various ecological niches actively, especially in Eurasia, and even gave rise to several new families, including predatory boars (Carnoporcidae) adapted to feeding mainly on meat and small animals. This is an exclusively Eurasian group of animals: the hyena-like deinaper lives in the temperate steppes of Central and East Asia, varaha lives south of the Himalayas (mainly in India), and mantahungal lives even further east.
Externally, mantahungal resembles varaha more than deinaper, but it is smaller and has shorter legs and a flatter and wider skull than varaha: body length is about 170 cm, shoulder height is about 100 cm, and weight is up to 250 kg. Males are larger than females. If varaha is a scavenger predator, then mantahungal is more omnivorous and is ready to eat anything that gets in its way. This is one of the least specialized members of the family: in its food preferences, it is much more reminiscent of the extinct wild boar of the Holocene epoch, although animal food makes up more than two thirds of the diet. The wool color of this animal is light brown with dark longitudinal stripes on the back, resembling the juvenile color of a wild boar.
Mantahungal swims better than other species of predatory boars, although it is less common on the sea coasts. Much more often, this animal stays among freshwater marshes and along the riverbanks and lake shores, where it often digs into the mud and earth in search of small animals. Its tusks are less flattened and curved than those of varaha – not hooks, but the edges of a hoe; spreading digits and wide hooves are adapted for movement through mud and swampy soil, and it swims well.
Mantahungal is a rather formidable opponent, capable of attacking small herbivorous mammals. It also eats large reptiles and can fish in drying ponds. An adult animal of this species is a dangerous opponent, capable of chasing prey for a long time. Nevertheless, local predators often prey on piglets or young animals that appeared without parental care. Most often, mantahungal dies from various diseases and parasites, especially parasitic worms, which it receives through fish and snails.
Mantahungal is a polygamous species; the mating season is not clearly defined, but more cubs are born during the rainy season. Sexual dimorphism is clearly manifested: males of this species are stronger and larger than females. One male usually has several females living in a vast territory, and he mates with them, while other males (including his own sons in adolescence) are driven away – fights between males can be very violent, often ending in huge scars on the body. Females, on the contrary, get along relatively well with each other – they live in groups of several individuals bonded by blood relationship, but each female gives birth to her brood in the den and at first keeps constantly next to the cubs. Later, when the cubs get stronger, she takes them out of the den and reunites with her herd. There are 4-5 piglets in the brood. They live with their mother and aunts until they are about one and a half years old, after which the male father drives them away.
The life span of a mantahungal is no more than 20 years.

Armor-headed wart hog (Geophacochoerus subterraneus)
Order: Even-toed ungulates (Artiodactyla)
Family: Pigs (Suidae)

Habitat: savannas and light forests of Southern Africa.

Picture by Amplion

Ancestor of present species is usual in Holocene African wart hog (Phacochoerus). These hoofed mammals spend significant part of day in holes dug independently. And its descendant has finished this habit of life to extreme being shown on ground surface only at night. This animal spends day in shelters – wide holes at times directed downwards to two meters depth and stretch under ground to tens meters. In connection with such original habit of life the shape of animal had strongly changed.
The armor-headed wart hog reaches height only 40 cm at a shoulder. But its body is very much extended – almost meter longwise not including tail. About 20 % of body length the head turned to tunneling mashine amounts. At this animal there are large, slightly bent tusks sticking up forward and in sides – this animal digs and deepens holes, at feeding on surface overturns stones in searches of insect larvae and digs out plant tubers and rhizomes by them. At the top part of head thick layer of cornificate skin protecting head from casual fallings in holes is advanced. Tip of muzzle with “snout” characteristic for pigs is very mobile that partly compensates hindrances created by tusks at feeding. Nostrils of animal are closing during digging. Nasal courses are rather short but the olfactory surface forms numerous plicas: at armor-headed wart hog it is very sharp sense of smell. Sight of animal is rather weak; eyes are protected from ground by dense eyelashes. Ears are small; at digging they fold lengthways and nestle to sides of head. On cheekbones the large bone outgrowths especially advanced at males stick up.
Body is long and legs are short. On forward legs in front, and on back ones under hock there are calloused outgrowths serving as a support at ground digging (animal digs a hole standing “on knees”). Hooves are wide; at digging they are used for shoveling up the dug ground. Hairs on body are submitted by short thin bristle, “mane” on back characteristic for wart hog is not present. Skin is wrinkled and grayish-black. At the tip of long tail there is brush of white hair: tail is used for communication and signal submission.
Armor-headed wart hogs live in groups: dominant male, female and cubs of current litter (up to 5 cubs 2 times per one year are born). At new litter birthing at the female grown up young animals are driven out. The family of animals lives in constant territory which is jealously preserved against neighbours. At the territory usually there is a main hole and plenty of temporary refuges well known to all family of hogs. In due course holes are extending, sometimes systems of holes join to each other. At exhaustion of food sources around of main hole the family moves (at night or dawn) to other hole, somewhere to the edge of territory. Gradually the centre of territory is actually displaced here that inevitably results to revision of borders between neighbours.
In each hole there is a main chamber where the female with posterity lives, and “throne hall” where the dominant male lives. They are located opposite to each other and between them main burrow with two exits (one of which is disguised outside by dust) passes through. On each side of this pass animals dig out temporary toilet chambers leaving dung there. After filling the chamber is filling up by ground and simultaneously the new chamber is making. This way animals hide their presence from predators.
In holes of armor-headed wart hogs a plenty of “lodgers” settles: butterflies, crickets, numerous fleas (they parasitize in thin wool on throat and stomach of animal). Among vertebrates large tortoises and lizards (hogs simply can to have eaten small reptiles) and also birds and small mammals settle in holes. For protection against parasites wart hogs willingly take dust baths sometimes arranging place for bathing right in heap of ground thrown out from hole.
Family of armor-headed wart hogs goes for feeding at night. At first male appears from hole; he looks, listens and smells around determining whether there is no danger. If all is quiet he walks out and after him female and cubs appear. At night animals go to watering place (if the water source is far some burrows to it are dug allowing to not show itself to superfluous danger at the watering place) and then feed on meadow or under trees. The basic forage of armor-headed wart hogs is grass. But in trees and bushes fructification season they willingly eat drop fruits and berries. Animals willingly eat forage of animal origin: worms and beetle larvae gathering them at hole digging, searching under stones or in rotten wood. Differing in keen sense of smell such pig easily feels presence of larva under thin layer of wood and if it is necessary splits mouldering tree by sharp tusk. If it is possible to find carrion or remains of predator’s catch animals willingly feed with meat.
During feeding armor-headed wart hogs communicate wagging with white hairy brush on the tail tip. Their voices at this time are similar to usual pork grunt. Tail sharply lifted upwards is an alarm signal: having seen such mark animals cease eating and start to smell around trying to find out predator. In case of danger animals squealing shrilly rush to nearest hole trying to keep near it at all. These pigs are fast and maneuverable runners though they can not run long on short legs. At deviation male climbs to the hole at last having turned to predator by head. He loudly roars trying to frighten predator and from time to time makes aggressive lunges trying to strike attacking predator by tusk. Usually after that only a little number of wishing to continue chasing ones may be founded.
Maturity at females comes at two-year-old age, at males little bit later. Young females at the second year of life pair the first time and approximately after three and half months give rise to posterity. The first litter is insignificant: no more than three pigs and usually only two ones. But at the fourth year of life in litter it may be up to five pigs.
Young growth abandons parents shortly before birth of next cubs or right after it. Youngsters first time keep in parental territory using for life old holes - at them tusks are still insufficiently grown. But when the young growth new litter grows up, the dominant male, their daddy, expels all of them from territory. At this time young animals perish in a plenty from predators. But ones managed to find suitable place for life, have an every prospect to live up to old age: the age limit of these animals reaches 15 years.

Galapagos beach boar (Thalassaper litoralis)
Order: Artiodactyls (Artiodactyla)
Family: Pigs (Suidae)

Habitat: Galapagos Islands, coastal areas and shallow sea waters.

Picture by Pavel Volkov

After human colonization of the Galapagos Islands, the appearance of the unique local fauna has changed significantly. Giant tortoises have almost completely died out, and descendants of introduced mammals occupy a significant place among local land animals. One of them is the Galapagos beach boar, which inhabits the coastal areas of the islands. This species is a true marine animal that lives solely on the seafood.
Galapagos beach boars resemble a caricature of a pig – they are runty animals with an elongated body and short strong legs. From their ancestors, domestic pigs, they inherited a light skin coloration – gray or whitish-gray with black spots of various sizes on the head, back and rump. These pigs are relatively runty, but quite large, with a well-developed layer of subcutaneous fat. The body length of the largest boar is up to 160 cm, height at the shoulders is up to 50 cm. The head is very large and heavy, with a short, not mobile neck. The movable muzzle is equipped with a keratinized snout, necessary for digging up the marine soil. The nostrils close with special valves during diving. These pigs have large tusks that help dig up the ground and fight enemies, including rivals from among their congeners. Galapagos beach boar has small eyes with slit-like horizontal pupils that see well underwater. The animal’s ears are small, equipped with a skin valve and a cartilaginous semicircle that supports the auricle in a closed state. On shore, a special muscle opens the ear, allowing the animal to hear well.
The animal’s legs are adapted to walking on a hard surface and to swimming under water. There are 4 digits on the foot, of which 2 lateral ones do not reach the ground, but they are well developed and connected to neighboring digits by skin membranes. There is also a small membrane between the 3rd and 4th digits for easy swimming. A swimming animal spreads its digits and paddles water with all its limbs. Animals use two swimming styles: alternating rowing with their limbs and simultaneous (“galloping”) paddling with their forelegs and hind legs. In the latter case, the spine is also involved. Less often, the animal swims due to the bends of the spine in a vertical plane with its hind legs stretched out and its front legs pressed against the body. A swimming animal has its ears flattened against its head. The tail of the animal is thin and short, not participating in movement. It is required only to give visual signals to congeners. The animal’s hooves are sturdy, allowing it to climb rocky shores – despite its clumsy build, Galapagos beach boar is able to climb steep stone slopes.
This pig species is omnivorous, equally willing to eat plant and animal food. The incisors are directed forward and form a kind of scraper for rasp away benthic animals and algae from rocks. The roots of the molars form late, and they grow up for a long time, compensating for the teeth erasure by coarse food. The animal is capable of chewing even clams and sea urchin shells. Thanks to this food, the body receives a lot of calcium, which contributes to the strength of teeth and bones. The bones of the ribs and limbs are thickened and massive, which makes diving easier. The beast can dive to a depth of 20 meters and stay underwater for up to 10 minutes.
At low tide, these pigs graze in the tidal zone in herds consisting of a male, several females and their cubs. They feed on algae, beached fish, and invertebrates (including jellyfish). The animals willingly eat hard-shelled invertebrates (crustaceans and mollusks along with their shells); thanks to their strong teeth, they thoroughly grind the shells to a state of sand. At high tide, herds of these pigs swim and dive for algae, gather crabs, clams, and starfish from the seabed, and skillfully drive shoals of fish onto the shore. Outside of feeding time, animals spend time on the shore, gathering in several harems and setting up something like rookeries. The animals bask in the sun for a long time before diving into the sea for food.
Twice a year, the female brings offspring: up to five well-developed piglets. During the first week of life, they do not approach the water and wait for their mother to return to shore. Grown-up cubs learn to swim in sheltered shallow bays under the protection of a large old nurse. By the end of the second week of life, the piglet is already able to swim and dive well. Young animals mature in the first year of life, but they do not live for a relatively long time: the average life expectancy of this animal in nature does not exceed 10 years, and only the strongest males live up to 15 years. The enemies of these animals are sharks, which occasionally swim up to the shores.

Cerdito-peluda (Insulosus volcanica)
Order: Artiodactyls (Artiodactyla)
Family: Pigs (Suidae)

Habitat: Galapgos islands, open country, scrub and forested areas. Is distributed on all large islands due to its ability to swim well.
Mankind managed to not wholly “deflower” the Galapagos Islands, early emphasis placed on its uniqueness and conservation resulted in the eradication of some invasive species, and the preservation of native ones. But introduced kinds of animals still left their mark, and evolved new forms, among these founders was the Domestic Pig (Sus domesticus). Cerdito-peluda is relatively small for a pig, reaching about 60 centimetres long with a shoulder height of up to 40 centimetres. Coat is a pelage of soft bristles, denser than that of its ancestor but not as thick as that of other wild pigs. From this it gains its common name, Spanish for “hairy little pig”. Colour is a fawn brown, with darker stripes running longitudinally along the body, this is a trait gained atavistically from the Wild Boar (Sus scrofa), predecessor to the Domestic Pig. Males bear an upright mane of stiff bristles of dark color, and have prominent tusks, especially in older individuals. Head is fairly large proportionally, and bears a disc-shaped “snout” by which it digs and forages in the soil, ears are large and hairy on the outside. Exposed areas of skin are dark reddish-brown in color, the pink of its ancestor being prone to sun-burn.
Social grouping consists of herds of up to 20 animals, a harem style arrangement of a male with many females including their offspring. Young males live in bachelor herds with weakly expressed hierarchy. Diet consist of fallen fruit and seeds, soft vegetation, fungi, eggs of ground nesting birds, carrion, and occasionally small vertebrates and insects.
Lead male within the herd maintains authority by antagonising subordinates, but also helps to fiercely defends comrades from predators and territorial interlopers.
Females produce young 2 times a year, litters of up to 6 piglets, which are nursed within a secluded “nest” made of dry grass, obscured and hidden by undergrowth or bushes. Young mature quicker than at its domestic ancestor, individuals are able to walk and run within a few days, and are sexually mature within 6 months. Lifespan may be up to ten years but is usually as short as six years.

Crimean pygmy boar (Neosus tauricus)
Order: Even-toed ungulates (Artiodactyla)
Family: Pigs (Suidae)

Habitat: Crimea Island in Fourseas, landscapes of various types.

Picture by Alexey Tatarinov

During late Cenozoic pigs had proved their evolutionary success, having settled on to all Eurasia and Africa. In human epoch they have had the minimal losses: areas of widespread species had been reduced, and some endemic species and subspecies have died out. But after disappearance of mankind they have quickly returned to initial positions. Large ruminants were strongly exterminated by people, therefore pigs have taken advantage of the situation formed in biosphere, and have evolved some new families becoming analogues of large ruminants in certain degree. Representatives of the initial branch of pigs, true pigs, also were kept in Neocene due to their universality and abilities to adaptation.
During the formation of Fourseas Crimea had turned to island. There the rests of local fauna which evolved in isolation during several millions years were kept. Prominent feature of local species is so called island dwarfism – very small size in comparison to continental species. One characteristic local species is Crimean pygmy boar, the descendant of Holocene wild boar (Sus scrofa), widely settled and successful species of ungulates. Appearance of this animal is characteristic and recognizeable. Crimean pygmy boar has shape characteristic for pigs, with more flexible snout, rather than its ancestors, resembling early stages of evolution of snout of trunk boars. Length of its body is about 60 cm at growth less than half meter at a shoulder. At this species there are rather long legs permitting to run quickly and to swarm up rocks. Colouring is skewbald – usually head and legs are colored lighter than body, but extreme variants exist: almost entirely black colouring with white legs and almost white one with dark longitudinal strip on back. This species is adapted to life in rocky landscape: it swarms up mountains excellently, and is strong and hardy. This pig can run on narrow rocky eaves and clamber on slopes. By nature this wild boar is very cautious and has good hearing and sight.
This is a gregarious animal; Crimean pygmy boar moves in small herds numbering 10 – 15 ones ruled by the most skilled and strong male. In places most frequently visited by them tracks are well appreciable, and if the track stretches through bushes, among thickets the tunnel on which animals move one by one is formed.
Having kept an omnivorousity characteristic for pigs, it eats animal food – reptiles, rodents, insects, worms, bird eggs – much more often, than its ancestors. At an opportunity this animal willingly eats carrion. But as it grows the diet passes to herbivory, and the oldest individuals frequently leave in marshy sites of island with plain relief and soft vegetation. Usually beyond the breeding season males of Crimean pygmy boar are tolerant to each other.
Heat happens in December – January, but even that time male skirmishes seldom are out of limits of simple display: males rise wool growing on back and nape, scatter ground by hooves and stamp legs. Pregnancy lasts till about 90 days. The female, as a rule, gives rise to two pigs of the same gender – it is connected to limitation of habitats of this animal. Cubs are born in reliable lair: usually in a cave in rocks or in specially dug holes if caves are not present. The same holes and caves are used by years and pass from generation to generation. Pigs are born striped, but as they grow their colouring changes: strips vanish, or, on the contrary, extend. Depending on genetic features colouring of adult animals varies in great degree. Young animals are fed with milk till 1 – 1.5 month; at this time the female lives separately from herd and leads very secretive life. After the young growth will get stronger enough, female bring cubs to the common herd. Females become independent at the age of 8 – 8.5 months, males – at 11 – 11.5 months. The sexual maturity comes in 2 years, and then young males are frequently expelled from herd by the leader. Representatives of this species live up to 37 years.

Swamp boar (Sinaper paludiphilus)
Order: Artiodactyls (Artiodactyla)
Family: Pigs (Suidae)

Habitat: marshes and swampy forests of the Far East.
In the human era, pigs showed high survival abilities, despite the extinction of some species of this family. The survived species easily regained their numbers and experienced a period of rapid evolution in Early Neocene. The descendants of the wild boar (Sus scrofa) are very diverse in Neocene Eurasia, ranging from the relatively little-changed Crimean pygmy boar to specialized trunk boars and porcippulas. On the plains of China, there is another pig species of a “traditional” appearance – the swamp boar.
The height of an adult at the withers is up to 80 cm, the body length is 150 cm, and the weight is about 70 kg. Swamp boar is a longer-legged animal compared to its ancestor; it has a more mobile neck and an elongated head. The hooves are able to move apart, allowing it to walk on swampy ground; there is a skin membrane between them that helps it swim.
The tusks in the upper jaw are relatively large, curved, pointing up and to the sides. The lower canines point upward and with the mouth closed, their tips protrude in front of the tusks. The lower incisors are inclined outwards and form a kind of shovel to make it easier to pluck plants out from swampy soil – in this feature the beast is convergently similar to the European flattooth, a representative of trunk boars.
Otherwise, it has changed little compared to its ancestor: bristles have become rarer and rougher, and the snout is slightly more flexible. The animal’s nostrils close by skin valves, so the swamp boar can graze in shallow water, dipping its muzzle into the water up to its eyes level. The wool coloration is more often dark brown, less often there is a weakly pronounced juvenile longitudinal stripe pattern on the back against a light general background.
Swamp boar feeds mainly on vegetative food – stems and roots of marsh grasses, ficus fruits that have fallen to the ground, and berries. The beast readily eats frogs and snakes, dead fish, crabs and crayfish, wounded birds or eggs that it finds in the reeds. Occasionally, this boar eats mushrooms and frog eggs. The animal swallows snails and beetle grubs along with vegetative food. In the north of the range, during the winter cold snap, animals move to life in the forest. Outside of the breeding season, swamp boar is solitary animal; only the female leads young piglets of the current year, and the one-year-old animals stay together in litters.
The mating season takes place in December and January. At this time, fierce fights take place between the males, and sharp tusks are used. The tough skin on the chest and shoulders of males serves as a kind of natural armor, so the blows of the tusks can only cut through the upper layer of the skin. Adult males carry numerous scars from mating duels. Pregnancy lasts about 18 weeks. There are usually 6-8, sometimes up to 10 cubs; the female gives birth to them in a secluded place, usually on an island surrounded by a swamp. At first, piglets hide in a shelter, but from the second week of life they already accompany the female. In the first 4-5 months of life, they retain their juvenile longitudinal striped wool color. Lactation lasts for 2 months, and by November, the female expels the grown-up cubs. At this time, their mortality rate is especially high – only a third of swamp boars survive the first year of independent life. Females reach sexual maturity by the age of 2 years, males by the age of five years. Life expectancy is up to 19 years.

Great Porkoceros (Ceratodens babiroussoides)
Order: Artiodactyls (Artiodactyla)
Family: Pigs (Suidae)

Habitat: Lowland rainforest and swamp forest of northern Meganesia.

Picture by Alexey Tatarinov

During the Holocene, the continent of Australia had suffered heavily from introduced animals of all kinds. Due to the harsh nature of the climate, most hoofed animals have disappeared as the neocene progressed. Sheep were too poorly adapted to the deserts, and too reliant on man, for example. The camels, practically pre-disposed to an arid existence, proliferated and came to dominate the dryer part of Meganesia. The other exception are the feral pigs, versatile and adaptable, they evolved to Meganesian equivalent of rhinoceros, the Great Porkoceros. This creature is a browser of low growth in the extensive rainforest and swamp forest of northern Meganesia, much like the Holocene forest rhinoceros.
This animal is built similarly to a rhinoceros, attaining 1500-2000 kilograms. The animal has an extensive barrel-chest and a bulging stomach which possesses an extensive gut. Unlike its predecessor, it subsists entirely on plant matter.
Its limbs are sturdy, but thinner compared to those of a rhinoceros. Broad hooves spread the animal’s weight in soft or swampy ground. The shoulders come to a distinct hump, which serves to support its thick neck and tremendous head.
Head of this animal is large and deep, with a broad snout compared to the body, and has large flaring cheek bosses which serve as protection during combat. The upper tusks of its ancestor have become the analogue of a rhinoceros horn. The cylindrical upper tusks project through the top of the snout, like those of a babiroussa, except that they project upward in the manner of 2 large horns, the tusks of the female are smaller and more slender. The lower tusks are strongly reduced. The animal is mostly hairless, possessing a thick, leathery hide of chocolate colour. Hairs only persist on the tail tuft, ear tufts and along the neck. The cartilaginous nasal cap is reduced and sits under the skin, while the lip extends outward in a small proboscis like that of a rhinoceros.
The face and sides of this animal are covered in heavy, wart-covered calluses. These are to protect the animal from serious injury during combat with one another.
As it browses, the Porkoceros clears distinct trails in the undergrowth; these trails are also used by other forest dwelling animals, which browse on the regenerated growth that emerges after the animal has passed. The Yagil and the Marsuipial panther are able to attack this beast, but they prefer to catch the more vulnerable juveniles, which have less-developed tusks and dermal thickening. This animal is predominantly solitary, only coming together to mate and to compete for mates. Rutting and breeding season takes place at the height of the dry season, allowing the females to raise the young in a safe, dry nest.
The female gives birth to 3 or 4 young at a time, and suckles them in a large shelter made from branches and lined with soft bedding. The newborn piglets possess lengthwise light stripes on a dark background. When the males compete for females, they display their tusks as a stag would his antlers, rasing their heads and showing them side-on. When in combat they make blows to the body and face with their tusks, and push against each other with their shoulders, in an attempt to exhaust one another. Great Porkoceros have a lifespan of up to 40 years; males that reach old age often have partly broken tusks and large scars from fighting.
Smaller relative Lesser Porkoceros (Ceratodens hirsutus), reaches only 150 kg, and is covered in light brown hair, which forms a crest along its back, which is lighter. It only possesses medium-sized protruding upper-tusks, which cross over each other; lower tusks are present and quite large. It mainly inhabits the dryer central scrub and grassland, where it feeds on herbage and shrubs, and some small amounts of softer grass. It prefers to shelter in large areas of scrubland, where it is able to hide more easily. The Marsuipial Panther frequently preys on this animal. Lifespan of up to 35 years, but usually much shorter.

Plain-dwelling tapirolalomena (Proboscilalomena tapirops)
Order: Artiodactyls (Artiodactyla)
Family: Pigs (Suidae)

Habitat: shrubby savannas of Madagascar.
Holocene pigs turned out to be very lucky animals. Widespread, rather unspecialized, and evolutionarily flexible, they managed to survive the Holocene-Neocene extinction event with minimal losses. And at the beginning of Neocene, the descendants of pigs occupied new ecological niches, partly substituting large ungulates. Some of them are convergently similar to extinct animals, or to inhabitants of other regions. So, in Africa, the bushpig gave rise to heavy-built forms resembling brontotheres and bulls. And in Madagascar, in competition with the local phobocornid bovids, some species evolved from the local bushpigs, that have a convergent similarity to the Eurasian trunk boars. One of them is the plain-dwelling tapirolalomena.
This pig species has adapted to life in open spaces. The length of the animal’s body is up to 150 cm, the height at the withers is about 70 cm. The wool color is light brown with darker vertical stripes on the sides, and a “crest” of rough grayish hair grows along the backbone on the neck and shoulders. Females are slightly more massive than males. The snout is transformed into a short proboscis. Tapirolalomena is a fairly tall-legged animal capable of fast running: at short distances, the animal can reach speeds of up to 50 km/ h, and trots for quite a long time at 30 km / h. This species lives in groups of 5-7 individuals: a male, 2-3 females and cubs of the last litter. Each group lives in a certain territory, along which it moves, adhering to an approximately constant route. During the movement, the herd tramples and eats the growth of shrubs, therefore, in the habitats of these animals, wide paths stretch through dense thickets of shrubs, and if the shrub is tall enough, tunnels form in it. Tapirolalomena feeds mainly on soft food: young leaves and fruits of shrubs, as well as mushrooms – this is the only thing, apart from water, for which the animal is ready to kneel down on its front legs. Tapirolalomena eats softer leaves than phobocorns, and prefers areas more heavily overgrown with shrubs and trees, so it does not compete so much with them. When encountering an unfamiliar opponent, males usually behave quite aggressively: they roar, open their mouths and push each other with their sides. When familiar animals meeting, only an exchange of sound signals takes place. With the help of various sounds, animals communicate while feeding in bushes or among tall grass.
The mating season of this species takes place at the beginning of the dry season. At this time, males court to the females: they gently touch them with their proboscises and sides (at other times, females treat such signs of attention aggressively), and drive competitors – mostly young males – away more often. After four months of pregnancy, the female gives birth to one or two well-developed cubs. Usually, the cubs of all the females of the group are born at the same time or with a small time difference. Shortly before giving birth, the female sets up a shelter in the bushes, where the cubs spend the first days until they get strong enough to keep up with the adult animals. At the age of one week, they leave the shelter, and the herd continues its usual way of life. Since the dry season is not over yet, milk is an important source of moisture for the cubs. They wean off milk at the age of 6 months, but they stay with their mother for about a year. Usually, one of the twins dies, but if the dry season is short, both cubs survive. At the age of one and a half years, the young animal reaches adult size, and at the age of two years it becomes sexually mature and capable of reproduction, although active growth lasts up to four years. Life expectancy is about 30 years.
The mountains of Madagascar are home to a larger mountain tapirolalomena (Proboscilalomena monticola). It has dark brown wool with a black stripe along its back, and its hind legs are slightly longer than its front legs, so animal’s back has a slight forward tilt. It deftly runs along mountain slopes and jumps on rocks, and can feed on grass and mosses. The jungle zone of the island is home to the saddled tapirolalomena (Proboscilalomena ephippifera), a brown beast with a gray saddle-shaped spot on its back. It is more massive and sluggish, and in addition to leaves it eats young branches, mosses and herbaceous plants of the undergrowth.

Deinolalomena (Deinolalomena horrida)
Order: Artiodactyls (Artiodactyla)
Family: Pigs (Suidae)

Habitat: Madagascar, grasslands.
Pigs of the Neocene epoch are one of the most successful groups of ungulates. Very widespread, unspecialized, and evolutionarily plastic, they gave rise to a bouquet of new forms that partially replaced the large ungulates of the Holocene epoch. The most successful species among them was the bushpig (Potamochoerus larvatus), which is widespread in Africa and Madagascar. It became the ancestor for a number of bizarre forms of massive ungulates, which became analogues of bulls, rhinoceroses and tapirs in Africa and Zinj Land. Madagascar Island became another center of adaptive radiation of these ungulates, where several forms convergently similar to various suids of Eurasia and Africa evolved in isolation. One of its descendants, deinolalomena, became a large scavenger of savannahs of the island.
This species is a large fast-running animal. The height of an adult at the withers is about 1.5 m, the body length is about 2 m, and the weight is up to 1000-1200 kg. Externally, this animal resembles a cross between a pig and a warthog. The animal’s body is covered with sparse reddish-brown hair, with a black stripe stretching along its back, turning into black hair on its tail. A white tuft of elongated hair grows at the tip of the tail. The problem of heat emission is solved by a fold of skin hanging down on the chest, like in zebu. The beast also has elongated movable ears, the skin of which is pierced with blood vessels.
Deinolalomena has a large head with elongated jaws, and a movable snout of a characteristic appearance. Two pairs of well-developed tusks protrude from its mouth, growing sideways and upward. They are used as weapons in tournament battles, but if necessary, the pig drives away predators, using them. The molars are thick and have well-developed cusps. Bone ridges grow on the head above the eyes, and powerful jaw muscles are attached to them.
In the absence of hyenas and other specialized scavengers from among carnivores, deinolalomena partly occupies their ecological niche. This animal feeds mainly on carrion of varying degrees of freshness, but it also drives predators away from prey and can kill a small animal that is not fast enough. At short distances, it gallops at speeds of up to 60 km/h, catching up the cubs of local ungulates phobocorns, as well as ground-dwelling lemurs.
Outside of the mating season, this species is a solitary animal that does not tolerate the proximity of beasts of its own kind. The mating season takes place from October to December. At this time, males chase the female, trying to mate with her. The female, being ready to mate, emits a musky scent and marks the grass and trees with her urine. Having found a female, the male behaves aggressively, chasing her for a while and biting the skin on her sides; then fast mating follows, and the animals leave each other. When two males meet, a fight breaks out between them, accompanied by digging the ground with hooves, mild blows with tusks in the side (not with the tusk tip) and a furious roar. After six months, the female gives birth to four to six well-developed cubs. They have stripes of lighter color on their fur, and after a short time after birth they are able to follow their mother everywhere. At the age of 5-6 months, they begin to taste adult food, and by the age of one and a half years, young deinolalomenas are already completely independent. They reach sexual maturity at the age of 3-4 years. Life expectancy is up to 40 years.

Neolalomena (Neolalomena paludiphila)
Order: Artiodactyls (Artiodactyla)
Family: Pigs (Suidae)

Habitat: Madagascar, river valleys in the western part of the island.
After the human extinction, rapid adaptive radiation of the descendants of the bushpig (Potamochoerus larvatus) began in Madagascar. These animals began to conquer various ecological niches in the island ecosystems recovering from the devastation caused by human activity and changes in nature at the turn of Holocene and Neocene. Evolution on islands often parallels the evolution of continental forms, and sometimes gives rise to forms similar to those on the continent. This is what happened in Madagascar: bushpigs, possibly introduced by the Malagasy, gave rise to species similar to those on the mainland after the extinction of humans. One of them is neolalomena, an inhabitant of wetland biotopes.
It is a medium-sized animal, a little resembling a continental boaropotamus, with almost hairless skin, without tusks, but with jaws elongated like in flattooth. Body length is 150-177 cm, shoulder height is 75-80 cm, weight is about 180-270 kg (male is larger than female). Connective tissue pads develop under the digits, allowing the animal to walk on soft, swampy soil. The skin color is gray, and light, coarse hair grows on the back and upper part of the head. The skin is thick, especially on the back and sides: the skin folds in the lower part of the body look like the skin “armor” of an Indian rhinoceros of the human era. The ancestor’s snout has turned to a resonator that amplifies the roaring of these animals: the nasal passages swell slightly when the animals vocalize. Voice of neolalomena is similar to the pig squeal, but is much longer and lower pitched. In the evening and in the morning, the animals arrange “roll calls”, lasting up to half an hour and ending with sunset or sunrise.
Neolalomenas are solitary animals that occasionally keep in pairs: as a rule, these are young sibling individuals. The male usually occupies an area of about 2 square kilometers in a river valley or near a lake or swamp. The territory of the female is smaller. Neolalomena feeds exclusively on terrestrial vegetation, spending the day in the water or in the shade of shrubs, and at night it moves into the thickets of grass. Sometimes the animal stays close to giant porcine tenrecs. In the hot daytime, neolalomena goes into the water and wanders in shallow water, searching for aquatic plants. In the dry season, the animal searches for tubers of water lilies and aponogetons at the bottom of drying reservoirs.
The breeding season of this species falls at the beginning of the dry season. At this time, males are more likely to express aggression and fight with each other for the females, pushing one another with their snouts and biting the skin on the shoulders of the opponent. After about 100 days, the female gives birth to two cubs, rarely to one only. Young animals are covered with yellowish-gray fur with a dark longitudinal stripe on the back. At the age of one month, young animals gradually begin to taste the food of adults, and after 3 months they completely switch to vegetable food. At one year of age, they are completely independent; as a rule, at this time the female is already pregnant again. Young animals reach sexual maturity at 3 years of age, with a life expectancy of up to 65 years.

Spiny hog (Catasus hystricosa)
Order: Artiodactyls (Artiodactyla)
Family: Pigs (Suidae)

Habitat: tropical forests of Central Africa.

Picture by Pavel Volkov

During the Holocene-Neocene extinction, many species of animals disappeared, but pigs survived and retained a fairly high number. Being omnivorous and evolutionarily flexible, they have lost only some representatives that were brought to the brink of extinction by humans. Among the survived pigs, the most successful was the European wild boar (Sus scrofa), which gave rise to two groups of large animals. In Africa, the descendants of the bushpig and the warthog dominate. But even among other pigs, unusual forms have appeared – for example, the spiny hog, a descendant of the giant forest hog (Hylochoerus meinertzhageni).
Spiny hog lives in the undergrowth and shrubby thickets of the tropical forest, preferring areas of disturbed forest and areas along river banks. It is a large animal with a height of up to 95 cm at the withers; body length is 1.87 m, weight is up to 170-200 kg. The animal has a wedge-shaped head with a movable snout, and the tusks are well developed in both males and females. The skin is thick, and its upper layer is strongly keratinized; the wool is coarse, wire-like, of grayish-brown color. Male is larger and darker than female, and is often completely brown. Long yellowish-white spikes reaching a length of 5-10 cm and capable of rising protrude from the wool on the sides of the pig. In this adaptation, spiny hog resembles the Madagascar spike-backed tenrec. The spikes protect the pig from attacks of land-dwelling predators, but large predatory fishes can attack animals swimming in the river, aiming the soft belly and throat.
Spiny hog lives in groups – the male, his harem and offspring. These animals are territorial and tolerate the proximity of neighbors only in places of outcrops of certain minerals and salt, where they regularly visit to replenish their mineral reserves. Spiny hog feeds on grasses, shoots of woody plants, mushrooms and fruits, and eats invertebrates and carrion.
The mating season is extended throughout the year, and females ready to mate appear in the male’s harem regularly. In the course of competition, males encroach on each other’s harems (especially single males) and fight for females, pushing each other with their sides and shoulders. Occasionally, tusks are used, but due to the armor-like skin, the animals do not inflict serious wounds on each other. When defending against predators, the animal also uses its tusks and inflicts extensive lacerations on the enemy.
Pregnancy lasts about 5 months, and there are 4-5 piglets in a litter. The female gives birth to them in a den she has dug, and stays with them for the first week of their life. She leaves the offspring for a short time to feed and stays close to the den, always ready to defend the piglets. At birth, the spines on the skin of piglet are small and soft, and they become longer and harder at the age of 10 days. By this time, the female returns to the group and brings her litter with her. Usually, within 2 years, the female brings 3 litters of piglets. Lactation stops at 2 months, and at the age of 2 years, the spiny hog reaches puberty. Shortly before that, the young animals are expelled or leave the harem on their own, forming bachelor groups. Loners usually fall prey to predators. Males begin to reproduce at the age of 3-4, when they conquer their own territory and females. Life expectancy is up to 20 years.

Poaka-ngaherehere (Pseudochoerus sylvanus)
Order: Even Toed Ungulates (Artiodactyla)
Family: Pigs (Suidae)

Habitat: Lowland forests of New Zealand, North and South Islands, sub-tropical woods of North Island.
Run wild domestic pigs have left numerous descendants in the Neocene of New Zealand; Poaka-ngaherehere is one of them, name meaning “forest pig” in indigenous Maori language.
Poaka-ngaherehere differs from their domestic ancestor in smaller size, being only about 70 kilograms in weight and 60 centimetres tall at the shoulder. Also, their face is distinctive by broad, warty outgrowths on the cheeks and snout, supported by bony ridges underneath. Tusks are larger than the ancestral form, even approaching those of a warthog (Phacochoerus) in size, coat is sparse, short reddish bristles with pale stripes, retention of juvenile colour. Males have a long erectile mane on the back which forms a crest, face has pale markings around the eye and base of the snout, running in a stripe to the cheek, snout and feet are dark pink. South Island populations form a separate subspecies, having denser bristles and a slightly larger size.
This animal is most active at in the morning and afternoon, preferring twilight, its diet is omnivorous, typical for a wild pig, roots, fungus, fallen fruit and nuts, large invertebrates, carrion and eggs, rare live vertebrates are also sometimes taken. Sounders are relatively large, dominated by a big female, and groups follow trails worn down through the undergrowth, deviating from these to forage. Males form small bachelor groups, but elder males are generally solitary. Calls are reminiscent of those of a domestic pig, but higher in pitch.
Breeding season runs from July to October, when there are abundant stocks of food. Males seek out sounders of sows by scent, and produce strong pheromone secretions to communicate with rival males. Contests over males are less violent and damaging than those of its ancestor, as tusks also form a display structure, and warty growths on the face afford some protection. A single male will mate with multiple sows, although the mating period does not last long. Gestation is about 130 days; nest making precedes the birth of the litter by about a month. Litters are large, consisting of up to twelve piglets. As with other pigs, young can follow their mother on excursions at about two weeks old and are fully weaned by 3 months, at which stage contrasting striped baby colouring gives way to more subtle pattern of the adult. Lifespan is up to 8 years.

Poaka-maunga (Notosus montanophilus)
Order: Even Toed Ungulates (Artiodactyla)
Family: Pigs (Suidae)

Habitat: Mountain forests and upland slopes of mountains, North and South Island of New Zealand.
In the wild country of Neocene New Zealand, descendants of run-wild domestic pig of Holocene occupation are notable. A generalized ancestor has radiated into different habitats, producing new forms.
Poaka-maunga somewhat resembles Sus scrofa, the wild boar of the Holocene, but it is somewhat smaller and more compact in shape, with proportionately longer legs. Adults average about 80 kilograms in weight and shoulder height is 85 centimetres. There is a dense coat of bristles that gives it a shaggy appearance, but this is thinner in the North Island subspecies. Coat colour varies from light brown to dark brown or almost black, white markings stretch from the eye to the cheek. Legs are relatively long and aid it in walking on sloped or rocky ground; this animal is surefooted and can flee predators on slopes with ease. Accordingly its name translates to “mountain pig” in native Maori language.
Diet is similar to ancestor, but comprises more vegetable matter, mainly grass and roots, but also occasionally fungus, and fallen seeds from coniferous trees. Animal forage is still taken, worms, birds eggs, carrion and insects, but it takes up smaller portion of the diet in more open countryside. Poaka-maunga is mostly diurnal, but will also forage at twilight. These pigs live in small sounders compared to their ancestors, with males being solitary or in small bachelor groups, seeking out females in the breeding season. Calls are almost identical to their ancestor, grunts, squeaks and squeals.
Breeding occurs in late summer and early autumn, from February to April. Males will seek out female-led sounders by scent, and will actively compete for females. Males fight by biting and goring with their tusks, skin is thickened at this time of year to resist severe injury. A single male will mate with multiple sows, and after the mating period is over, he will leave. Gestation is up to 140 days, and nest-making starts in anticipation of this. The litter size varies by how healthy and how old the sow is, but it can be up to 10 piglets. Newborns weigh up to a kilogram, and compete for the best suckling. Piglets start following their mother away from the nest at two weeks; lactation is up to 3 months, but piglets star foraging at about 4 weeks old. Striped juvenile pattern fades to adult coloration after about 3 months. Lifespan is 12-15 years.

Poaka-wai (Australochoerus riparius)
Order: Even Toed Ungulates (Artiodactyla)
Family: Pigs (Suidae)

Habitat: Rivers, lake margins and marshes of North Island, New Zealand.
The domestic pig has followed Mankind to nearly every corner of the earth, in the Holocene, so valued is it for its meat. Feral populations thrived, and gave rise to many new forms in the Neocene, including in New Zealand.
One such form is the Poaka-wai, a large, semi-aquatic pig found in the rivers and marshes of the North Island, taking its name from Maori words for “pig” and “water”. In body shape it resembles a tapir, weighing about 250 kilograms and having a large head with a long snout, disk-shaped rooting nose is absent, and the animal has prominent lips with whiskers. In the shape of head and lack of oversized tusks it tends to resemble Cenozoic Anthracotheres, ancestors of the Hippopotamus. Tusks are mid-sized, pointed and do not wear against each other, used in defence. The toes are long and enlarged, forming a spreading, webbed foot for walking on marshy ground, hind legs are longer than forelegs and back slopes forward. This pig has a coat of short, coarse hair, again like a tapir, the animal is an all-over brownish grey, with the skin around the mouth and anus being pinkish.
In habits, it is semi-aquatic, feeding on submerged vegetation and also plants along the water margins, preferring water-weed, leaves and stems as opposed to reeds and grasses. It is able to “walk” along the riverbed like a tapir or hippo, but can also swim, as with all pigs. Though mostly solitary, females may remain with their piglets until they are a third of adult size. They are active mostly in the morning and evening, staying cool in the water in the high heat of the afternoon. When surfacing they may produce a grunting “blow” of spent air somewhat like a hippo does, and while feeding on land can make a soft grunt, distressed animal makes a loud squeal.
Breeding occurs during summer rains, from November to mid January, females will spend more time on land, and advertise receptiveness by producing a musky smell. Males will compete actively over females, wrestling and shoving with their heads, but not using their tusks. Males will also display by uprooting small trees and shrubs and throwing them about, mating is a protracted, occurring multiple times. The mother will find a suitably dry spot in which to make her nest, which is a shallow scrape in the ground lined with dead leaves, gestation is about 140 days. Only 4 to 5 young are born, unlike its domestic ancestor, and they are relatively better developed at a young age, having a faded striped colour. Young are able to follow their mother in the water after a week, and are suckled for about two months. Whelps start feeding on their own at about 5 weeks, and sexual maturity is reached by the females after one year, and males after two years. Life expectancy is up to 16 years.

Makkapitew (Makkapitew ferox)
Order: Artiodactyls (Artiodactyla)
Family: Peccaries (Tayassuidae)

Habitat: North America, grassy plains, semi-deserts, sparse woodlands.

Picture by Timothy Morris

Initial image by Alexey Tatarinov

The collared peccary, a pig-like non-ruminant mammal of the New World, was among the largest mammals of the New World to survive after the end of the human epoch. Numerous populations of this animal have been preserved in a vast range, and the gap in the range during the human era contributed to the accumulation of differences that became the material for subsequent natural selection. One of the descendants of the collared peccary evolved to peccason a giant herbivorous species. And next to it, another species roams the plains, differing from the giant of the plains in both size and diet.
Another branch of Tayassuidae evolution is represented by makkapitew, a very intimidating member of the family. In the territory of North America, it repeated the evolutionary experiment set up by nature in Eurasia and North America in the Tertiary period, and in Eurasia in Neocene. This representative of peccaries has become an analogue of fossil entelodons and Neocene deinapers: its diet contains significantly more meat than is typical even for omnivorous pigs. This animal is a scavenger and a small animal hunter. The body length of makkapitew is about one and a half meters with a height at the withers of up to 1 meter.
Makkapitew’s appearance retains the features inherited from its ancestors. This animal has a strong build, a poorly flexible spine and a relatively large head. Unlike typical peccaries, the head of the makkapitew is elongated, narrow, and lighter. The jaws of the beast can open at an angle of up to 100 degrees. The molars of the animal are pointed, of cutting type, with a very small chewing surface. The incisors are narrow and pointed, adapted for tearing meat. A characteristic feature of the beast is its long dagger-shaped tusks (hence the name: “makkapitew” in the Algonquian Indians language means “it has big teeth”). With their help, the animal kills small animals like rodents and snakes, as well as the cubs of large inhabitants of the plains. The long nasal passages allow the animal to distinguish odors subtly and find small animals hiding in the grass and the remains of prey of local predators. The animal’s muzzle ends with a small cartilaginous nose.
Although the makkapitew lives on dry plains, its head is a bit like that of a hippopotamus – the eyes are shifted upwards and raised above the skull on small bony elevations. Due to this, the animal has a good view. The animal also has large movable ears, similar to those of a donkey. Their task is not only hearing, but also heat emission.
The legs of makkapitew are relatively long – due to them, the animal can travel long distances, following herds of herbivores and searching for carrion. In its appearance, the beast looks a bit like the fossil Pleistocene peccary Platygonus. Makkapitew has a relatively long, thin tail with a thick tuft of black hair. It serves for communication: by raising their tails, the animals inform each other about their location.
This animal is covered with sparse coarse hair, and by winter it stocks a layer of subcutaneous fat and grows a thick undercoat. The wool color is brown with rusty sides, the head is darker. Males grow a short, erect mane of coarse wool on their necks and shoulders. The cubs differ from the adults in their lighter brownish-gray color with thin vertical stripes on their sides, allowing them to camouflage themselves among the grass.
Makkapitew lives on the plains of North America in herds numbering up to a dozen animals. A head of the herd is a large male with huge tusks, establishing a strict hierarchy. Other individuals are females and cubs and adolescents not reached puberty yet. Solitary animals – old or too young individuals – are often found on the plains. Family groups and single makkapitew individuals follow herds of herbivorous animals, but prefer not to attack them. They usually wait until some predator attacks the herd, and then take their prey from it, taking advantage of their numerical superiority. Loners, especially young males, are remarkable in their aggressive behavior and often even prevent predators from chasing prey. But they can predate themselves, attacking wounded or weakened animals and inflicting wounds on them with their tusks.
The female gives birth to one cub once a year. The young are born developed enough to follow their parents an hour after birth. The birth of makkapitew cubs takes place in the spring, when other inhabitants of the plains bring offspring, and it is easier for the mother to find food of animal origin. Up to the age of two years, young animals remain in the parental family, but then the dominant male drives them away. The females join new families and bear offspring at the age of three. However, males have a real opportunity to assemble their own family only by the age of four or five, when they reach full physical maturity.

Coyametl, or Elephantine peccary (Rhinotayassu coyametl)
Order: Artiodactyls (Artiodactyla)
Family: Peccaries (Tayassuidae)

Habitat: seasonally humid tropical forests and rainforests of Central America.
After the extinction of large mammals in the historical era, small and medium-sized animals all over the planet had got a chance to pass to a large-sized class. In North and Central America, Early Neocene was a time of vigorous adaptive radiation in pig-like animals of the peccary family. Grassland-dwelling herbivorous forms, fast-running scavengers, and even semi-aquatic forms evolved among them. In the tropical forests of Central America, a specialized forest-dwelling species has appeared – coyametl, or elephantine peccary (“coyametl” is the name of peccary in Nahuatl). Its closest relative is omiyanehe (Thalassotayassu omiyanehe), a large semi-aquatic peccary from the wooded southern regions of North America.
Coyametl is a relatively large animal, about the size of a tapir; this beast is its peculiar counterpart in the Central American rainforests. The weight of an adult animal reaches 400 kg or more, and males are larger than females.
The hooves of this species are thick, wide and blunted, expanding under load. A pad of elastic fat-impregnated tissue is developed under digits. Due to this adaptation, the animal can easily walk on swampy soil without falling through, and swim. Like its ancestors, it has 4 fingers on its front leg and 3 toes on its rear leg. The side digits do not touch the ground. The animal’s skin is black, wrinkled, and covered with very short and sparse blue-black hair. Only on the back and neck of animals is the hair longer and thicker, especially in adult males. The cubs look hairless – their hair is short and thin, and the mane is undeveloped.
The animal’s head is massive and wedge-shaped. The snout is elongated into a movable proboscis, like a tapir. The coyametl’s sense of smell is very acute – the inner surface of the nasal cavity and proboscis is covered with a wrinkled olfactory epithelium. The animal has rounded, mobile ears and very fine hearing, but its eyes are small and its eyesight is poor. To protect against the branches of the tropical forest, the eyes are covered from above with small bone ridges. Large canines grow in the animal’s mouths, but they are visible only when the animal opens its mouth.
This species is a solitary animal; only the female and her cubs keep together, and small bachelor groups of males exist, numbering 2-3 individuals. Animals mark their territory with piles of manure and urinate on tree trunks. Coyametl is silent – only in case of danger does the animal emit a loud hoarse squeal, and during the mating season the males roar, challenging their congeners.
This species is exclusively vegetarian, feeding on leaves, branches and fruits of shrubs and young trees, less often on grass and mushrooms. These animals trample down wide trails in the forest; shrubs grow there, being a source of food for small forest-dwelling mammals. Coyametl likes to graze near forest reservoirs – rivers, lakes and swamps. The animal prefers to feed on soft marsh and aquatic vegetation, swims willingly and allows small fish to clean its skin of parasites.
Animals really like to eat shrubs infested with sweet mealybugs, which are bred by pochteca ants. For the coyametl, it is a real sweet, although at the same time it receives a charge of formic acid from the ants protecting their mealybugs. Unfortunately for the coyametl, it cannot feed on bushes with mealybugs for a long time – the ants protect their herds too actively, and the most unpleasant thing for the coyametl is that the ants try to get into the eyes of the beast. Because of this, it is forced to cover its eyes with eyelids with slightly keratinized skin, and the skin valves close the nostrils at this moment. In cool weather, when the ants are less active, coyametl sometimes even manages to feast on young calathea plants from the plantations of pochteka ants.
For the pochteka ants, despite the damage caused by the coyametl, the proximity to this beast turns out to be useful – it actually helps the ants to clear the territory for new calathea plantations. In addition, coyametl leaves behind several piles of manure, which is so necessary for fertilizing the calathea plantations.
In spring, coyametls begin their mating season, when these solitary animals can gather in groups. At this time, males fight for females, inflicting lacerations of thick skin on each other’s shoulders. Often, a display of canines, accompanied by a roar, forces weaker opponents to retreat without a fight.
Pregnancy lasts about six months, and the birth of cubs occurs in autumn. Usually there are 2 cubs in a litter, but young or too old females have only one cub. The young are born developed enough to follow their mother an hour after birth. For about three months, young animals feed on milk, but usually by this time they have already acquired the diet of adults. The young animal leaves its mother by the beginning of the next mating season – at this time, due to the hormonal storm in their blood, the males seem even the cubs next to the female as rivals and attack them. Young animals try to find peer congeners in the forest and move around the border territories of adult animals in bachelor groups for about a year.
Puberty occurs in the 2nd year of life in females and in the 3rd year in males, with a life expectancy of up to 20 years.

Meuden (Nasotayassu vocifer)
Order: Artiodactyls (Artiodactyla)
Family: Peccaries (Tayassuidae)

Habitat: temperate and cool regions of southern South America, foothills of the Andes.

Picture by Alexey Tatarinov

By the end of the ecological crisis that engulfed the biosphere at the end of Holocene, peccaries turned out to be among those few large animals that survived the effects of human activity – hunting and habitat destruction. Being quite adaptable, these herbivorous ungulates quickly regained their numbers, expanded their range and gave rise to a number of new species. During the Holocene-Neocene glaciation, peccaries living on the southern edge of their range adapted to a colder climate, and during the retreat of the glacier, some of them settled in southern Patagonia and retreated to the foothills of the Andes. From these peccaries meuden evolved, being a very large peccary species from the Pampas of southern Patagonia.
The height of an adult individual at the withers is about 170 cm; the weight is more than a ton – up to one and a half tons in large males. The wool color is brown in various shades, from close to rusty-red to almost black. In winter, the wool becomes lighter and a thick undercoat grows. In old animals, the wool turns silvery, as if they turn gray. Males are larger and darker than females. Meuden is one of the few large animals in its habitat, along with the groundsloth rodent (Tardimegamys longimanus), but unlike it, meuden never leaves its habitat.
Another notable difference between males and females is the shape of the skull. In the male, the nasal bones grow strongly and form an openwork structure on the nose bridge and above the eyes, which supports a resonator sac formed of soft tissues, which can swell greatly. In females, the resonator is much smaller. A movable cartilaginous snout develops at the end of the elongated muzzle. The lower jaw of the animal is strongly elongated; the lower lip is fleshy and mobile, contacting with the snout tip. There is a small cutout in the middle of the lower lip, dividing it into two halves that can move independently of each other.
Meuden feeds on grass and branches of shrubs; the animal is able to pluck grass only with its lower lip, but it eats shrubs using both jaws. Long triangular canines curving downwards protrude from the animal’s mouth – they serve for self-defense, and also help to pull bushes out of the ground and strip bark from trees.
This species lives in herds, numbering 4-7 adult animals in summer and 12-50 individuals in winter. The herd moves slowly over an area of 100-200 km2, so as not to deplete resources. Herds of small ungulates often stay close to these animals – they notice a predator earlier and sound the alarm, and meuden can drive away many predators. In winter, small ungulates also take advantage of the fact that the meuden digs up the snow in search of food. The adult meuden has few enemies – only the jagueira (Eironca horrida) and large raptor cats (Felinoraptor andinus) can attack an adult animal, but they also prefer to hunt cubs and adolescents. The leader of the herd is the male, and a strict hierarchy develops in the herd. Animals display a dominant position to their congeners by pushing them with their sides. To protect themselves from predators, the herd organizes a collective defense: adults stand in circle with their heads outside, growl, dig the ground or snow with their feet and shake their heads. The dominant male often leaves the line and threatens the predator, trumpeting loudly and opening his mouth wide.
Rutting season in meuden begins in early to mid-autumn, when large herds begin to gather and the animals are in good physical condition. At this time, males push one another with their sides and dig the ground with their feet, but they never use their tusks during tournaments. Most of the females go to the leader, and skirmishes usually occur between the leaders of separate groups who appeared in the same herd. The female’s pregnancy lasts for 9 months; usually meuden gives birth to 2, less often 1 or 3 cubs. The cubs feed on their mother’s milk for almost a year, after which they completely switch to adult food. At the age of 4 years, the animals reach puberty and leave their parents, and the following spring they form their herds. Usually, animals find each other and form herds based on “winter acquaintances”, memorizing the smells of congeners with whom they spent winter in the common herd. Life expectancy is 45-50 years.
In the foothills of the Andes and in the forests of Tierra del Fuego, a smaller subspecies lives – the forest meuden Nasotayassu vocifer notalis. It differs from its plain-dwelling counterpart in its smaller size (height at the withers up to 140 cm, weight about 700 kg) and dark brown, almost black coat color. It also has shorter, thicker and stronger canines. Also, this subspecies never gathers in large herds, preferring to keep in groups of no more than 10-12 individuals.

Yesin (Yesin bengalensis)
Order: Even-toed ungulates (Artiodactyla)
Family: Shevrotains (Tragulidae)

Habitat: coast of bay of Bengal and Jakarta Coast, mangrove forests.

Picture by Tim Morris

In human epoch people of Myanma (Burma) believed in existence of tiny aquatic elephant. They named it as “yesin” and attributed to it some unusual properties: poisonous bite and mystical power above common elephants. In opinion of some cryptozoologists, the real animal was behind a myth. But, unfortunately, the mankind had died out, not having found out the truth.
Neocene yesin, the unusual representative of shevrotains, a family of primitive artiodactyls, is named after this mythical character. As well as mythical yesin, it resembles tiny elephant a little, leads semi-aquatic way of life and lives also in territory of former Myanma.
Appearance of yesin is rather original: in constitution this animal is vaguely similar to tapir, but is much smaller than it is, and is built not so heavy. Yesin reaches 130 cm in length; its height at a shoulder is about 60 cm and weight is about 40 kg. The muzzle of yesin is extended as a proboscis used at diving as a respiratory tube. Both at males and at females from the upper jaw impressive canines grow: at males they reach the length of 15, at females – of 10 cm. These canines not only allow to dig silt and sand in searches of food, but also serve as a weapon. Yesin it is capable to wound seriously any animal attacked it, and males use canines for courtship tournaments. Ears of yesin are of medium size, rounded and mobile. At diving they can fold along the head and nestle against it closely. As the adaptation to aquatic way of life the special structure of hoofs serves: they are wide and have a membrane between them, and allow the owner to swim and to walk on fenny ground perfectly.
The animal is covered with short wool of chocolate-brown color with light yellow “apron” on throat and breast. The lower side of short tail is white – it is a mark which the female uses for communication with cubs. Cubs have masking albesent strips and spots on body.
Yesin is secretive animal leading mainly twilight way of life. This animal spends daytime in dream among rich roots of mangrove trees. It repulses possible enemies with the help of advanced canines, but quite often seeks safety in flight, diving and hiding under water for a long time.
Yesin is omnivorous, but prefers food of animal origin. The basis of its diet is made of seafood – fish, crabs and molluscs which it catches in water or digs out of sand and silt during outflow. Also this animal digs clutches of reptiles at sandy coast and ravages bird nests made on the ground. Also it does not disdain carrion. The small part of yesin food is made with vegetative food: algae and fallen fruits.
Only for the pairing period these animals, usually not tolerating the presence of relatives, meet each other: males arrange tournaments, fighting for females. Usually these tournaments pass without blood and are limited to display actions. Males inflate proboscis and puff air out through densely closed nostrils, uttering high squeak. Thus they open mouth wide and show canines to the contender. If rivalry becomes especially sharp, contenders attack against each other and strike each other by lateral impacts of head. Thus canines only slightly touch skin of contender. Biting the contender, yesin male only bites its skin by forward teeth. But protecting itself from predator, yesin sticks points of canines into skin of enemy.
The female gives rise to one, and in rare cases to two cubs depending on mother until they will reach the age of 6 months. The female brings posterity not more than once per year. Young animals become sexually mature at the age of two years; life expectancy in nature does not exceed 30 years.

Habitat: Kalimantan, tropical forests.

In Holocene, ungulates suffered greatly due to human persecution and habitat destruction: almost all species larger than pigs or goats became extinct in most parts of the globe. The smaller species weren’t much luckier: they faced the same problems, but a number of their species managed to maintain a fairly numerous population. After the extinction of mankind, the survived species began to revive and gave rise to a whole bunch of descendants, including large ones. Chevrotains also took advantage of this opportunity: large and amphibious species appeared among them. A peculiar representative of large chevrotains, a long-toothed deer, lives in the tropical forests of Kalimantan; it is a descendant of the Java mouse-deer (Tragulus javanicus).
This species reaches a large size compared to its ancestor: body length is up to 1 m, tail length – 4-6 cm, height at the withers up to 70 cm and weight is about 40 kg. Wool color is monotonous reddish-brown; the only contrasting spot is the white underside of the tail, which is a sign that the female uses to communicate with her cubs.
A peculiar feature of this deer is the structure of its teeth: the upper canines of this species are hypertrophied, like those of a babirusa. They bend up and back, piercing the skin of the upper lip on the sides of the muzzle and forming a kind of protection from overhanging branches above the animal’s muzzle. The lower pair of canines is also large: in males, they protrude upward from the mouth. In older males, the upper canines are especially large, and sometimes they ingrow into the skin of the forehead, while the lower canines develop so much that they prevent the animal from chewing. Such males have difficulty feeding and often produce fewer offspring, although they are most attractive to females. Long-toothed deer is very cautious and prefers to escape from predators by running, diving into the water if possible. The alarm signal in this species is very characteristic and sounds like a mix of a moan and a sheep bleating.
This species has wide hooves that can spread apart, increasing the support area on soft swampy soil. The lateral hooves are also well developed and help to move on soft ground.
This species feeds mainly on soft food: herbaceous plants, mushrooms and fallen fruits. Occasionally they eat eggs of ground-nesting birds, carrion and ground-dwelling invertebrates. Long–toothed deer is a solitary one, less often it forms groups of up to three heads – usually a female with cubs or young immature animals. Males always live alone and do not tolerate the company of their congeners. This species has no specific breeding season, and in the forest it is always possible to find both breeding-ready and caring for offspring females. Communication between different individuals occurs with the help of musky secretions of the inguinal glands: animals crush tree seedlings under themselves and drag them between their bellies and hind legs, smearing odorous secretions on them. Males search for females by scent, and often several competing males gather near one female. Fighting for the female, the males shake their heads, displaying their tusks, and dig the ground with their feet, as well as urinate profusely and utter warning calls – staccato bass barks. If no opponent backs down, they start “boxing” with their front legs.
Pregnancy lasts 185-195 days. A female gives birth to 2 cubs, less often one only – in old or very young female. Usually the cubs are born from different males. The cub’s wool is covered with numerous white spots that fade with age. Lactation lasts about 3 months. At about this age, the animals begin to grow tusks: milk canines just stick out of their mouths, like in wild boar, and fall out soon, being replaced by permanent ones that grow through the skin. At the age of 10 months, the young animal is completely independent, at 14-16 months it reaches sexual maturity. Life expectancy is 10-14 years.

A similar species, the saber-toothed deer (Odontotragus smilodonidens), lives in Sunda Land. Its length is up to 70 cm, height at the withers is 50 cm. It differs from the previous species in coloration: numerous light spots are scattered on its body. The canines of this species are directed downwards and protrude strongly from the mouth; in males they are larger than in females and serve for intraspecific displays. The females have moderately long canines well developed in both jaws, and they inflict bites on the predator, protecting their offspring. In such a situation, they utter loud calls resembling a dog bark. It is possible, that the disruption of the range is connected to the extinction of closely related forms on Jakarta Coast because of the competition with representatives of the thunderhorn family. This species avoids the competition due to the inhabiting of the drier parts of the forest and in highlands. This species feeds on ground plants, including leaves of young trees.

The idea of the deer with curved canines was stated by Simon, the forum member.

Deersimil (Cervops platycornis)
Order: Even-toed ungulates (Artiodactyla)
Family: False deer (Neocervidae)

Habitat: savannas and light forests of Southern Africa.

Picture by Lambert

After extinction of significant part of large hoofed mammals their place was occupied with representatives of other groups of mammals: in Palearctic there are large running descendants of lagomorphs, and in Nearctic and Neotropic areas – descendants of South-American rodents. Only south of Africa appeared rather isolated from the Sahara savanna by woods and mountains. Here again species of herbivorus mammals have remained relicts of Holocene dominant: various hoofed mammals, descendants of small antelopes and chevrotains.
Occupying ecological niches exempted after mass extinction they turned to species similar to well-known in human epoch antelopes and deer. At some species even big horns have appeared – it is a rarity among Neocenic herbivores.
The deersimil is not the most numerous species among South-African hoofed mammals. It keeps in small herds sometimes together with other species of herbivores. This animal is the descendant of small and short-legged African chevrotains (Tragulus). Having remained out of competition from the side of bovines chevrotains roughly have started to evolve having formed the separate family of false deer – rather large swift-footed hoofed mammals.
In comparison with ancestors deersimil is a sizable animal: its growth at a shoulder is up to 1.5 m, body length is up to 1.6 m. By constitution it resembles small antelopes and gazelles. This is one of most swift-footed hoofed mammals of Neocene: at short distances deersimil accelerates momentum up to 80 kms per hour. Because of long legs usual pace of this animal is an amble but deersimil develops maximal speed running gallop.
Colouring of deersimil helps it to hide among vegetation: body is covered with chestnut-brown wool; on groats and hips there are thin vertical strips of yellow color. Stomach, bottom part of neck and head sides are white. Cubs are colored lighter: the basic colouring at them is straw-colour with longitudinal brown strips on body (by colouring they are similar to boar piglets); on groats and hips strips are bent downwards. In process of growth striped pattern on the body vanishes and on hips becomes more contrast.
This animal has horns on head. But as against deer horns deersimil horns are constantly growing (not dropping as at deer), shovel-like and with several jags (“antlers”). These horns are a little similar to horns of African prehistoric giraffes Sivatherium. Bases of horns are enough strong and extended along of skull; horns grow on head of animal in parallel to each other. Horns of females resemble more longitudinal crests with two jags at back edge. At males horns are larger and it can be up to 5 - 7 jags on them; horn tops at males slightly inclinate in sides. New jags appear on forward part of horn: at old males horns are sometimes similar to rooster crest. Similarly to deer deersimil uses horns as the tournament weapon - opponents approach to each other so that horn jags get in dredgings on contender’s horns. At the duel basically a power struggle takes place – contenders try to push aside and tumble down each other.
From senses at deersimil hearing and sense of smell are most sharply advanced. Other herbivores use it watching for behaviour of these animals for detection of probable danger. In case of alarm the deersimil utters special shout - sharp whistle warning of neighbours and other animals grazed near about danger. Rescuing from predator deersimil hopes for the speed in many respects - few predators can catch up adult animal full of forces. Even two-day cubs are already almost equal in speed to adults though, certainly, they get tired much faster.
Deersimil eats mainly graminoids. Grazing animal bites off only their tops; after feeding of this animal other species of herbivores can find enough food at the same place to themselves. Especially deersimil likes cones of graminoids in condition of wax ripeness: thus some graminoids differ in sweetish taste. Usually deersimil feeds during dawn and sunset and spends hottest time of day in tree shadow.
For protection from overheat deersimil uses the original adaptation – its own horns. As against deer horns they are always combined by alive growing bone. Outside of breeding season skin on horns is plentifully penetrated with blood vessels serving as fine radiator: blood emits heat to air. But in breeding season because of hormonal influence blood vessels in basis of horns are narrowed and substantially block stream of blood to horns that protects males from blood loss at casual wounds.
Breeding season at deersimils begins at the end of rain season. Between males there are short skirmishes for “harem” of several females (depending on physical condition male can declare rights to 4 – 10 females). Opponents usually avoid to enter direct fight and all can be limited to demonstration of force: males bellow bassy, dig ground by hoof, widely open mouthes and show teeth. Sometimes they rear and showing to each other the might make some steps on rear legs. Usually one of contenders leaves stadium without fight.
Time of pairing proceeds only about one week and then aggression of males is reduced also they become tolerant concerning to each other again feeding sometimes side by side.
After dry season female gives rise to one or two cubs (about half of females fawns twins). As at all hoofed mammals cub is born advanced and in some hours it is capable to follow mother. First two months it feeds by milk but from fortnight age it already tries plants copying mother. To the end of rain season it becomes independent, but stays in herd. Sexual maturity at females comes at the age of one and half years, at males at two years.

Oranmyian (Paracervops oranmyian)
Order: Artiodactyls (Artiodactyla)
Family: False deer (Neocervidae)

Habitat: tropical forests of West Africa, north of the Congo basin.
Representatives of non-specialized animal groups have a much higher probability of survival in the event of an ecological crisis than specialized species. Representatives of the chevrotain family (Tragulidae) managed to survive in the era of the global ecological crisis at the turn of Holocene and Neocene. During the Ice Age, the area of tropical forests decreased, and a significant part of the chevrotain population appeared in the territory occupied by savannas and woodlands. In the course of evolution, the descendants of chevrotains formed an independent family of false deer, medium- and large-sized herbivores that developed antler-like outgrowths of the skull. Some of the false deer have developed life in the savannah: these are the deersimil (Cervops platycornis) and related forms. But another part of the population has adapted to life in the jungle and woodlands. Oranmyian is the largest of the forest-dwelling representatives of the false deer family.
This is a fairly large animal: body length up to 115-125 cm, height at the withers 70-80 cm and weight – 25-30 kg. The animal’s wool is dark brown with a reddish sheen. In its appearance, the oranmyian resembles a small deer: antler-like horns with a small flattening and bumps growing in a row along the rear edge of the antler grow on the animal’s head. In old animals, these bumps turn into small tines. In front of the base of each horn, there is another outgrowth – straight, pointing forward and slightly bent to the side. The front edge of this process is greatly expanded: this process is used to push the branches apart. Females have significantly smaller horns than males. The horns of oranmiyan are covered with rough skin; young individuals have velvety fur on the skin, but it quickly wears off, especially on the anterior horn process. Like in a deersimil, these antlers do not shed, but constantly grow. The damaged horn is deformed during the restoration process; sometimes additional outgrowths appear in the places of cracks.
This ungulate species has relatively weak jaws and teeth: these beasts feed on herbaceous plants, leaves and various fruits, and also willingly eat mushrooms and carrion. Animals often go out to areas of damaged forest or to the shores of reservoirs, where they eat grass and leaves of young trees. Males have large canines.
Oranmyian lives in small herds – 5-8 adult animals and first-year cubs. The herd is always led by a large male; the young males form temporary bachelor groups. Usually, the meeting of two adult males goes quite calmly: they only stamp their feet and shake their heads. Young individuals are more aggressive, and adult males butt heads with them, trying to hook the opponent’s horns with their own horns and knock it down. Sometimes animals bite each other.
The mating season of oranmyian begins in late September and early October. Ready to mate, females secrete musk and leave odorous marks by rubbing their rumps against tree trunks. There are minor skirmishes for females between males at this time, but even at this time they more often come down to displays, roaring and digging the ground with their hooves. During the rut, males eat little and often mate with females. The rut ends after about two weeks, after which the males become more peaceful. After 185-195 days, the females give birth to 1-2 cubs. There are white spots on the fur of young animals that fade around the age of one month. Young animals stay in the herd for up to the age of one year, and then the males are driven out by the herd leader. Young females sometimes go to another herd or follow young males, and sometimes they stay in the parent herd. Puberty occurs at the age of 2-2.5 years. This species usually lives 12-14 years, and only few animals live up to 16 years. Usually, females live longer than males.

Sunhorn deer (Heliocervus heliocornis)
Order: Artiodactyls (Artiodactyla)
Family: Deer (Cervidae)

Habitat: eastern part of North America, light forest and bushes in plain and foothill areass of Appalachian Mountains.

Picture by Meh

Till whole human epoch, since prehistoric times, deer were traditional object of hunting. Chasing of these animals had resulted in their preservation only in few places of their former area. In Northern hemisphere these places represented remote northern grounds, Siberia in Eurasia and area of Rocky Mountains in North America. After the ending of human epoch some small deer species preserved in forests of Southeast Asia. These animals became ancestors of new species of deer of Neocene epoch.
North American deer are descendants of white-tailed deer (Odocoileus virginianus) – one of the most usual species of the family at this continent. One of descendants of this species is magnificent sunhorn deer. It is medium-sized deer – adult male weighs about 100 kg, female is much smaller. For this one gracile constitution is typical – this deer is able to run quickly. Sunhorn deer lives in light forest areas where bushes alternate with sites overgrown with grass. The basis of ration of this animal is made of leaves of bushes and low trees and also of rather soft grasses not belonging to graminoids.
The body of sunhorn deer is covered with wool of bright yellow color; dark longitudinal strip stretches from the nape up to the basis of tail. Occasionally at separate individuals in adult condition attributes of juvenile colouring keep – white spots on shoulders and hips. Stomach at females is white. At males colouring of stomach is quite another – it is white with numerous black spots. This colouring is used by males for display in courtship season. The bottom part of tail at individuals of both genders is white. Vertically rised tail making seen a wrong side appreciable from apart is the traditional alarm signal at deer.
Deer are an excellent example of action of sexual selection. Various species of these animals during the history of this group developed horns of various sizes and shapes. Extreme degrees of expression of consequences of action of this kind of selection are fossil deer Megaloceras with huge horns and Eucladoceras on which fan-shaped horns more than ten antlers developed. Sunhorn deer had actually repeated an evolutionary way of fossil deer Eucladoceras – its horns have completely lost function of the tournament weapon, and have turned to object of courtship display. The shape of horns of this deer has determined its name. Horns of sunhorn deer have set of antlers which grow practically in one plane. In the basis of such horn there is wide semicircular “shovel” as at the elk, but turned vertically. On its edge numerous straight antlers grow, because of what both horns of this deer create the impression of stylized solar disk with beams. At adult males it may be up to 8 – 11 and even more antlers on each horn. In courtship season males avoid combat, being limited to displaying of horns. Females of this species are polled; it is typical condition for all deer, except for odd-looking skewhorn from Greenland.
Within summer season males of sunhorn deer concern to each other tolerantly and even form barchelor herds numbering up to 20 individuals. The courtship season begins in the middle of an autumn. At this time horns completely ossificate, the rests of skin fall down from them, and deer males become aggressive. Males of this species gather at “stadia”. They display themselves to contenders, rearing. Keeping balance, male can make too many steps in vertical position. Thus spotty colouring of its belly becomes especially good seen. Usually males compete; they try to keep longer a vertical position – this way the strongest one is revealing among them. If rivalry is critical, males can pass to active struggle against contenders: they push each other by chest, trying to tumble the contender down. Occasionally they strike impacts to each other with the help of forelegs.
The winner male gathers a harem of 5 – 8 females and within several days repeatedly couples with them. He furiously rushes to every one, in which it sees the contender (even to animals of other species), and during the courtship season eats almost of nothing. To the end of courtship season male is strongly exhausted, and some males even perish, including from a nervous exhaustion. In winter males mew horns.
Pregnancy lasts about half-year, and cubs (usually twins) are born in spring. Juvenile colouring of sunhorn deer is spotty: cub is darker, than adult individual, and on brownish background of its wool white spots are scattered forming faltering longitudinal strips on back and sides.
To an autumn young deer leaves mother, and at this time she is ready to new pairing. At the second year of life young females take part in breeding season the first time. Males can take part in courtship tournament only since the fifth year of life. For the second year they grow primal small horns which have few antlers and no “shovel”. Each new year of life horns become larger, and at five years get the shape characteristic for horns of adult animal.

Littoral deer (Paramazama caprops)
Order: Artiodactyls (Artiodactyla)
Family: Deer (Cervidae)

Habitat: far south of South America, Tierra del Fuego; sea coasts.
In the human era, there were up to ten species of deer of Mazama genus, which occupied various habitats in Central and South America. In the epoch of the global environmental crisis, most of them became extinct. First of all, the extinction affected forest-dwelling species – a significant part of the forests were destroyed by human activity or during climate change. The survived Mazama species were adapted to life in the cold climate of the south of the continent or in the Alpine habitats. They gave rise to several South American deer species of the Neocene epoch. In due course of evolution, deer had to share habitats with deermaras – running rodents. Deermaras prosper in tropical and subtropical climates, and in the cold regions of the continent, the dominant herbivores are the descendants of brocket deer.
Littoral deer is an inhabitant of the southernmost regions of South America. It inhabits wetlands with patches of deciduous forests and thickets of shrubs on the coast of the continent, as well as on nearby islands. It is an animal slightly larger than a goat, characterized by a strong physique. The height of the littoral deer at the withers is up to 70 cm. It has sturdy legs of moderate length, and its hind legs only slightly longer than the front ones.
The specifics of the habitats caused the appearance of some features in the animal’s anatomy. The hooves of the littoral deer are wide, able to spread apart, and are connected by a short membrane at the base of the toes. Due to this feature, the deer easily walks on marshy soil and can swim well. Littoral deer easily cross the sea straits several kilometers wide, swimming from one island to another.
The animal’s head is elongated; the ears are small, covered with thick hair on the outside. In the mouths of animals of both sexes, sharp short canines protrude, used to defend against enemies and as tournament weapons. Males have larger canines than females. Antlers are present only in males; they are straight and pointed, lack lateral processes and are slightly similar to goat horns. The antlers shed annually.
The wool color of the littoral deer changes with the seasons. The winter coat color is lighter with variations from almost white to yellowish. In winter, the animal’s wool is thicker and longer. The summer coat is rarer and shorter, brown with shades from reddish to dark chestnut. The tip of the muzzle is always white.
This deer species feeds mainly on soft vegetation – broad-leaved grasses, foliage of shrubs and low-growing trees. At low tide, the animals come out onto the littoral zone and feed on the seaweed thalluses. In winter, when the foliage falls from trees and shrubs, this deer feeds on the littoral. At any time of the year, littoral deer come to the seashore for food of animal origin. Littoral deer often eat starfish and storm-tossed fish. With hoofbeats, it splits the shells of sea urchins and clams and eats their contents.
Littoral deer usually live in groups of a dozen individuals or less under the leadership of a male. The seasonality in reproduction in this species is clearly expressed. Rutting occurs in the fall. Males behave aggressively towards each other. During tournaments, they make barking sounds, trying to establish a hierarchy without using brute force. If this does not help, the animals butt heads, as is typical for deer. In case of violation of the hierarchy, the dominant male may bite the opponent’s shoulders and legs.
In early summer, the female gives birth to one well-developed cub. It stays with its mother until the start of the rutting season, but often does not leave her during its first wintering season. Puberty in young animals occurs in the second year of life. Life expectancy usually does not exceed 12-15 years.

The idea of the existence of this mammal species was expressed by Jaldithas from Philosophica-Dixonia.

Andean deer (Oromazama andina)
Order: Artiodactyls (Artiodactyla)
Family: Deer (Cervidae)

Habitat: Andes Mountains, high-altitude regions.
Ungulates have suffered significant damage in the historical era – the ranges and species diversity of many groups have significantly decreased due to human activity. During the Neocene, the abundance and diversity of these animals recovered in many parts of the world. In South America, deermaras, cursorial caviomorph rodents widespread in the warm regions of the continent, became competitors of ungulates. On this continent, ungulates are represented mainly by descendants of Mazama deer. Rodents compete with them in warm and warm temperate areas of the continent, but in cold areas the evolution of Mazama deer has been successful. The littoral deer (Paramazama caprops) lives in the far south of the continent, and Andean deer inhabits the cold regions of Patagonia in the mountains, far from the coast of the continent.
It is an animal with a strong physique, adapted to life on mountain slopes. The body length of an adult is 85-100 cm, the tail is 4-6 cm long, the height at the withers is 55-67 cm, the height at the rump is 67-80 cm, and the weight is 25-30 kg. The hind legs are longer than the front legs and the back of the beast is sloping – this is a characteristic feature of mountain-dwelling animals. The hooves are wide, with a large footprint. Due to them, animal can easily move along the mountain slope, clinging to the slightest irregularities of the stone.
The color of the thick wool is brown or gray with multiple transitional variations in local populations. Young animals tend to be darker colored than adults. The male’s head is decorated with strong antlers; the main branch of the antler is thick, with numerous bumps on its surface. The number of branches on the antlers increases with age and reaches 3-4 in old animals. The largest branch is directed forward from the base of the antler, while the others are much shorter and grow outward. Females are also horned, but their antlers are smaller and do not branch as much – usually only old females have a second process on their antlers, but young females have simple needle-like antlers. Antlers are used in border conflicts for displays, as well as for protection from enemies. The short and wide ears are very mobile, covered with fur on the outside; the auricle can fold lengthwise to protect from the cold.
The Andean deer lives on high-altitude plateaus with sparse thickets of shrubs at an altitude of 2,500 m above sea level. It inhabits meadows and forests on mountain slopes, and occasionally enters rocky deserts. The basis of the diet consists of grass, leaves, young shoots and twigs of bushes. This deer also eats moss and scrapes lichens from rocks. Due to the shortened strong jaws, the animal can eat coarse vegetative food. This deer usually leads a solitary lifestyle, being active during the day. At night, these animals hide in natural shelters – caves and crevices. Sometimes females with cubs form groups of 2-4 adults.
The rutting season begins in winter, in June and July. At this time, real fights take place between males equal in age and physical condition – the animals chase each other, trying to hit the opponent’s rump, backbone or neck with their front legs. If this does not help to establish a hierarchy, the animals butt heads, trying to knock down the enemy with a movement of their antlers. 200 days after mating, 1 or less often 2 fawns are born. At the age of 3 months, young animals switch to adult food, and at 8 months they are already independent.
Andean deer reach puberty at the age of 2 years, but males actually participate in mating duels only from the age of 4. Life expectancy is 10-12 years.
A close relative of the Andean deer, the black-headed deer (Oromazama nigriceps), lives on the mountain slopes and in the valleys of the northern part of the continent. It is approximately 1.5 times taller, weighs up to 60 kg and constantly keeps in small herds – up to 5-6 adults. This species prefers to stay in mountain forests and shrubs. The head of this deer is covered with black fur, and there is a black stripe along the backbone. Antlers usually have only 2 branches.

Maned spirocervus (Spirocervus jubatus)
Order: Artiodactyls (Artiodactyla)
Family: Deer (Cervidae)

Habitat: Himalayas, mountain forests.
In human epoch the majority of large animals had been exterminated as a result of hunting, or their areas and number had been strongly reduced because of destruction of habitats. As a result after human disappearance the majority of large animals had died out, not having left descendants. Their place was occupied by large descendants of more successfully survived small species of animals.
Asia was the most densety populated continent of human epoch. This circumstance became the reason of practically general degradation of natural ecosystems and extinction of large animals. But in Neocene this continent appeared populated by large animals again. One of such species is the descendant of small barking deer (Muntiacus muntjak) which lives in Himalayas. This animal is equal to large deer of human epoch in size (height at a shoulder up to 120 sm, weight over 150 kg) and is the approximate analogue of bezoar goat of human epoch. Similarity is strengthened even more by the shape of horns of this deer – they have no characteristic branchy shape and are mostly straight with spirally twirled edges. This feature has determined the name of animal – spirocervus (literally “spiral deer”).
Spirocervus has robust constitution; its rear legs are little bit longer than front ones, and back is inclined forward. It is the prominent feature of herbivores living on hillsides – it is easier so to graze. Also at spirocervus there are strong hooves behind which the elastic small pad is located. Hooves can easily move apart. Due to such features of structure of legs the animal is able to move on abrupt stony slopes though prefers to live in mountain forests.
The high mountains differ in rather cold climate. The alternating of seasons is clearly expressed here, and it is cold weather till the significant part of year. Spirocervus is adapted to such features of mountain climate. The thickset constitution reduces a relative surface of its body. Brown colored wool of this animal is long and rich. In cold months it becomes thick, but does not change color, as at snowlopper from the number of hoofed lagomorphs, living higher. On breast and neck of spirocervus males long mane grows, and tail is ended with magnificent switch of white color.
Head of spirocervus has odd appearance. On head of this animal two longitudinal bone crests from nostrils up to the bases of horns grow – it is a characteristic attribute of barking deer descendants, including massive bulldeer of China swamplands. At the female bone crests are less expressed, and horns are lack. And horns of the male have very unusual shape. They consist of two antlers – the basic one growing upwards, and lateral one directed aside and outside. The basic antler is straight; at the adult male it reaches the length 70 – 80 cm. It is three-edged in cross-section and is slightly twirled spirally. Lateral antler is short, thick and hook-like. It serves for fixing horns at courtship tournaments.
Bone crests pass to bases of horns. They are covered with long wool of yellowish-brown color at males and grey at females. At males wool on bases of horns is so long, that it seems the continuation of mane.
Spirocervus precisely differentiates habitats with snowlopper. It avoids places where snow lays till the most part of year, and does not meet higher in mountains where the snowlopper lives. Usually spirocervuses keep in herds of 10 – 15 animals – females and young animals of both genders under leadership of the adult male. Sometimes in large herd it may be two adult males. These deer live in mountain forests and feed on leaves of bushes and low trees. In winter when leaves fall from most part of plants and forage reserve of animals is reduced, spirocervuses may eat leaves of evergreen rhododendrons which they usually do not touch in summer.
In the beginning of an autumn the courtship season begins. At this time males roar loudly, declaring rights to territory and females. Bachelor males (usually these ones are young animals) challenge males, interfering to their territory and roaring. Between competing males there are severe duels for harem. They are reduced to force struggle of animals linked by horns. Lateral antlers on horns serve as terminators, not allowing animals to injure each other; therefore males usually go through this time without damage.
Pregnancy at the female lasts about half-year, and she gives rise only to one well advanced cub. Such tactics is more favourable in conditions of limited resources. Cubs of spirocervus differ from adults in dark, almost black colouring, with several small white spots on throat. In the course of time they brighten, and the wool changes shade to brown color. To winter the young animal becomes almost independent. Females are ready to breeding at the third year of life. At males at the second year of life simple forked horns with almost equal basic and lateral antlers grow. Next years horns change the shape, in brief repeating an evolutionary way of ancestors of this animal – vertical antler becomes longer, and lateral one grows thick.
Life expectancy makes about 40 years.

Meganesian False Moose, Samboose (Paludicervus altus)
Order: Even Toed Ungulates (Artiodactyla)
Family: Deer (Cervidae)

Habitat: Swamp-forest, marshes and vegetated lake margins of Carpentary and Arafura lakes in northern Meganesia.
The urge to hunt trophies has caused man to propagate various large ungulates outside of their natural range. Deer have been introduced into many places they did not traditionally live, including New Zealand and Australia. In the north of Meganesia, deer still thrive due to this, and some have become adapted to the vegetated margins of the great sea lakes there.
The Meganesian False Moose is a very large deer, almost as tall as a true moose and weighing up to 500 kilograms, with males being larger than females. They have a massive body; humped shoulders, and long legs, feet are large with splayed pointed hooves to aid it in walking on marshy ground. Colour is a general dull brown, with darker parts along the spine and bases of the feet, a short mane tops the shoulders. The snout is long and tapered, with a large nose, the lip forms a short overhanging proboscis that aids it in gathering food, the antlers can reach a span of 2 meters, and are palmate much like a moose, with as many as 16 points.
This animal is an ecological analogue of a moose, but in a tropical setting. It will consume low-growing vegetation as well as the young shoots of trees and other waterside vegetation, twigs and bark, they frequently dredge the shallows of the lake for water plants of various sorts, fallen fruit is also eaten. Food is selected based on nutrient level as opposed to bulk, they are selective browsers. Though found on the margins of both Carpentary and Arafura lakes, this animal still needs to drink fresh water and will travel some distance to find it if it needs to. Both males and females are aggressive if threatened by a predator or rival, and will charge at threats, only the males have antlers, which are regrown each season. These deer are mostly diurnal, and generally travel alone.
Rutting and mating occurs at the end of the dry season from September to November, this coincides with the flush of new growth. At this time, rutting males become sensitive to the smell of the does urine, males and females start calling to each other, the rutting call of the male is a typical stag roar. Males will congregate around females and compete to mate with them, females select mates based on the size of antlers and males will display antlers vigorously in order to compete for females. Stags will sometimes be driven to duel and lock antlers in combat, with the weaker backing down. Gestation of the pregnant doe is 8 months, giving birth to a single large fawn. Fawns are a lighter colour than their parents, and bear a weak spotted pattern, as with many deer, the newborn will initially be hidden in a nest of thick vegetation until it is able to follow its mother. The young will stay until the following year when the next fawn is born. Lifespan is up to 20 years, and only the young are ever preyed upon by marsupial panther and yagil.

This species of mammals was discovered by Timothy Donald Morris, Adelaide, Australia.

Shishigami (Gravicervus shishigami)
Order: Artiodactyls (Artiodactyla)
Family: Deer (Cervidae)

Habitat: Japan Archipelago, tropical and subtropical forests.

Picture by Alexander Smyslov

The era of anthropogenic pressure was marked by a significant decrease in the number of large mammals, both predators and herbivores. The extinction of bulls and a significant part of deer provoked an explosion in the number of small herbivorous mammals after the mankind extinction. In the northern part of Eurasia, the descendants of hares substituted large herbivores, and in tropical areas, small deer had gone through an extensive adaptive radiation. A significant number of deer species have evolved in East Asia, resembling bulls and large antelopes in their massive physique – these are descendants of the small Asian muntjak (Muntiacus muntjak) deer. They are widespread in tropical and subtropical forests and woodlands. Some of their species have settled even in the temperate climate regions.
The Japan islands had regularly connected to mainland Asia by chains of temporary islets, which allowed massive deer forms to populate this isolated world. Millions of years of evolution have led to the forming of endemic species not found on the Asian mainland.
In the southern part of Japan Archipelago, in the area of tropical and subtropical climate, a large relative of the Asian bulldeer – shishigami deer – lives. This creature is a cautious and secretive forest dweller. The shoulder height of shishigami reaches 2 meters; in its physique, this species resembles primitive prehistoric giraffes. The front legs of this beast are longer than the hind legs, and the back is noticeably sloping. The neck is of moderate length, and the head is large and elongated.
Coloring helps shishigami to disguise itself in the forest. The wool on the animal’s body is yellowish-brown, with thin intermittent longitudinal stripes of black color. The background color is darker on the back, and lighter on the belly and legs. The animal’s head is entirely black with white spots above the eyes. In some individuals, the spots are larger and form “glasses” around the eyes, and additional white spots appear on the cheeks. Shishigami cubs are significantly more contrasting in color than adults. They have a spotted pattern like a leopard: numerous dark spots are scattered on a sandy-yellow background. Later, the spots merge into longitudinal stripes, and the background color darkens significantly.
The antlers of the shishigami are wide and short, they shed annually. Each antler forms a large main branch pointing backwards, slightly to the side and upwards, and a small process pointing upwards. Shishigami defends itself from enemies with the help of highly developed canines protruding from its mouth. The animal’s jaws can open wide, and the defending beast can inflict deep puncture wounds with its canines. On the other hand, highly developed canines make it difficult to chew with the help of lateral movements of the jaws, and the jaws themselves are relatively long and narrow. Therefore, shishigami feeds on relatively soft shrubby vegetation, leaves of large grasses and young shoots of trees.
This species is a solitary animal, with only a female and a cub keeping together. Shishigami is found in humid forests crossed by rivers. At the riverbanks, it feeds in thickets of large herbaceous plants, and sometimes enters the water to eat sappy and soft aquatic plants. The hooves of this animal are wide and capable of spreading apart. Due to this, shishigami can walk on muddy soil and swim.
The voice of this deer is a loud roar. It is heard in the forest during the mating season – in the northern part of the range it is late summer. In the south, where seasonality in shishigami breeding is not pronounced, the male of this species emits an advertisement call when sensing the scent of a female during estrus. Another sound that shishigami is capable of making is rapid prolonged barking, a danger signal. It can be heard far away in the forest, and forest dwellers know by shishigami’s voice about the presence of a predator.
The only cub is born in the spring and stays with its mother for up to six months. As a rule, the mother drives him away herself by the time of the onset of a new pregnancy. Sexual maturity of a young animal comes in the third year of life.

White-headed rapidocervus (Rapidocervus albocephalus)
Order: Even-toed ungulates (Artiodactyla)
Family: Deer (Cervidae)

Habitat: plains of North America – prairies and semideserts.
In human epoch in North America isolated populations of white-tailed deer (Odocoileus virginianus) were kept. In epoch of Holocene – Neocene congelation they lived in foothills of Rocky Mountains, in areas of humid enough climate, but far from edge of glacier. These populations became ancestral stock for deer of Neocene epoch, inhabiting North America.
Among American deer of Neocene epoch a special genus evolved, which representatives live in open area and have ability to very fast running. These animals are rapidocervuses, original analogues of pronghorns of Holocene epoch.
Rapidocervuses represent the small genus of deer including the forms living in open areas – from grassy plains up to semideserts. These animals are remarkable in their gracile constitution and long legs with strong hooves. Rapidocervuses are high animals (over 1.5 m at a shoulder) and have long neck. Head at these animals is short, and jaws are strong, adapted to feeding on rigid grassy vegetation. Eye-sockets are shifted upwards and are placed at small bony eminences formed also by antler pedicles.
Similarly to all deer species, rapidocervuses shed antlers every year. Antlers of these deer are poorly branched, and because of it animals look like gazelles or antelopes from apart. Usually antlers of adult male have no more than three branches. The main branch of antler is directed back; antlers have lyre-like shape with tips slightly bent in sides. The second large branch grows from the basis of antler and is directed forward, and on the basic branch there is one small branch directed upwards and inside. Females of rapidocervus species are hornless.
Typical species of group is white-headed rapidocervus living in western part of Great Plains, in dry area located in “rain shadow” of Rocky Mountains. It is a large species of genus; growth of adult male at a shoulder is about 160 cm. Female is smaller compared to male – it typical for all species of rapidocervus. At white-headed rapidocervus head is almost entirely white, except for top of head and nape. White color also is stretched to sides and forward part of neck, breast and stomach. Nape, back part of neck, shoulders, back, hips and crupper of animal are yellowish-brown; tail from above is black, and white from underside.
White-headed rapidocervuses live in plains in herds numbering up to 50 ones. They avoid thickets of bushes and trees, and any obstacles for run. Being frightened by predators, white-headed rapidocervuses, and also other large species are capable to accelerate momentum about 70 kms per hour, and small ones – up to 80 kms per hour on short distance. Rapidocervuses do not compete to deermaras, cursorial rodents of South American origin, due to difference in habitats – rapidocervuses are steadier against cold, live in northern areas and live in deserted regions to the west from plains. Besides they eat more rigid grasses uneatable for these rodents.
In rapidocervus herd there are approximately fifty-fifty males and females of various ages. The hierarchy in herd is well expressed – large male is a leader of herd. At meeting of two herds males try to establish leadership, rearing and striking each other impacts by front legs. Heat at this species takes place in the beginning of winter months, and the posterity is born in early spring. At white-headed rapidocervus female gives rise to one fawn, but approximately 20 % of females give birth to twins. Calf has spotty colouring, as at deer in human epoch. At change of colouring in places where there where white spots at adult animal, spots of juvenile colouring start growing and merge with each other. On one-colour sites of body they gradually decrease in size and vanish. At not sexually mature individuals head is dark, and only throat and tip of muzzle are white.
In territory of North America some close species of rapidocervuses live:
Grassland, or striped rapidocervus (Rapidocervus zebratus) – medium-sized species: growth of male at a shoulder is about 120 cm. At this species antlers have only two branches. The basic branch of antler is directed back and upwards a little, and on one third of its length, measuring from the antler basis, the second stag branches at small corner to the main one and reaches about the same lengths. Shoulders at this species are little bit higher then crupper, and neck is rather short. Colouring of grassland rapidocervus is very rare for deer: on yellowish-brown background dark narrow vertical strips stretch, being especially dense on back part of the body and on neck. Lower side of tail is white.
It is the most “water-loving” species of this genus: it lives in well humidified plains in eastern part of area of these deer, but keeps in the distance from bushes and trees. For this deer run by jumps up to five meters long is characteristic.
Crowned, or short horned rapidocervus (Rapidocervus coronatus) inhabits dry areas of Mexican plateau. It is the large representative of genus: growth at a shoulder of male reaches 140 – 150 cm. This species differs in colouring of head appreciable from apart: from upper lip through an eye up to the basis of ear wide black strip stretches; it is present at individuals of both genders. Below this strip the narrow white strip lasts. The basic colouring of body is monophonous sand-yellow with darker strip along the back; stomach is bright yellow. Antlers of this deer are rather short and carry three branches directed accordingly back, sideways and forward. All branches approximately one length and their ends are slightly inflexed, because of what pair horns is remote is similar to a crown. The bases of antlers are strongly expanded and covered with large corneous lumps – “pearls”.
For improvement of heat emitting at crowned rapidocervus the plica of thin skin on breast is developed, and ears of this species are rather larger, than at related species. This species has interesting behavioural feature – it is able to receive water from cactuses, breaking stalks of these plants by hoof.

Badland, or donkey-eared rapidocervus (Rapidocervus asellinus) is the smallest species of genus: height of adult male at a shoulder is about 60 cm. This species lives in droughty “badlands” kept along Rocky Mountains ridges. The gracile constitution and plica of skin on breast help to radiate the superfluous heat. But more effective bodies of heat emitting are auricles. They are long, narrow and mobile as at hare, and their tissue is plentifully penetrated with blood vessels.
Antlers at badland rapidocervus are advanced rather poorly. They have only two branches – larger one is directed back, and shorter one, sometimes having doubled top, is pointed forward. In constitution this species is very similar to gazelle. At this species lips are covered with dense skin: it is an adaptation for feeding on cactuses. Badland rapidocervus eats prickly pears covered with tiny hair-like prickles and because of it inedible for other herbivores, except for insects. Eating round stalks of cactuses, or simply looking around, this deer can stand on rear legs for a long time, supporting against any firm subject, or without a support at all. In diet of this species there are also dry grass and insects. In spring these deer willingly eat even poisonous tubers and bulbs.
Colouring of wool of this deer is monotonous yellowish-brown. As an element facilitating the recognizing of congeners at these deer there is only black tail with fluffy white inside.
For badland rapidocervus the low requirement for water is characteristic. It receives water from cactuses and excretes very concentrated urine containing small amount of water.

Aotearoan Wood-deer (Sylvadama novazealandiae)
Order: Even-toed Ungulates (Artiodactyla)
Family: Deer (Cervidae)

Habitat: Lowland forests, woods and bush, North and South Islands of New Zealand.

Picture by Alexander Smyslov

Deer had become a characteristic part New Zealand landscape during the human occupation of the Holocene, being introduced for the purposes of game hunting sport. Descendants of these animals remain in Neocene, and have given rise to large and small forms. One kind, descendant of Fallow Deer (Dama dama) became an exclusive inhabitant of woodlands and other well-vegetated areas.
Aotearoan Wood Deer is a fairly small kind of deer, converging somewhat upon a Muntjac in body shape, but without tusks. Adults reach up to 65 centimetres tall at the shoulder and 35 kilograms in weight, and males possess short, sharp 2 pronged antlers, ears are large and prominent. Body colouring is an all-over reddish brown, retaining a juvenile pattern, rows of white spots. Face, nose and feet are darker brown colour, tail and rump is white, used in signalling. Coat is soft and dense, but thicker in the colder parts of its range, the South Island. Facial glands are used to mark territory, and are larger in males.
A diet consists mostly of the leaves of trees and bushes, but also occasionally bark, soft grasses and herbs, as well as fallen fruit. These animals are active mainly during the twilight as well as late afternoon; they are generally shy and will flee at the first sign of danger. Call is a whimpering bark when alarmed; breeding males may make a high nasal trumpeting call to attract females. These deer are mostly solitary, but several individuals may exist within one territorial area, and they are generally tolerant of one-another.
Individuals reach sexual maturity at 2 years; females have more than one oestrous cycle during the year, but prefer to breed when food is abundant. Gestation lasts up to 7 months; fawns are sheltered in dense undergrowth for a week, and grow quickly, leaving the mother after 6 months. Males are polygamous, and a form small harem of females, fighting consists of displays where males thrash and uproot plants with their antlers, males will lock antlers and attempt to exhaust one another.

Related form, exclusive inhabitant of the dense sub-tropical woods of the northern part of North Island, is the Pygmy Wood Deer (Sylvadama nana). It is distinguished from its relative in much smaller size, 40 centimetres tall, and only 10 kilograms in weight, with underdeveloped antlers, single short, horn-like points. Coloration is darker, and spotted pattern is yellowish. This animal is a shy inhabitant of dense forest, and feeds selectively on low understory growth, leaves, fungus, stems, and fallen fruit, sometimes insects and small vertebrates are taken. Young is born larger and better developed than its relative.

This species of mammals was discovered by Timothy Donald Morris, Adelaide, Australia.

Njenge (Njenge njenge)
Order: Artiodactyls (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: swampy forests, river valleys of Central Africa.
During the human epoch, and further during the Ice Age, the area of tropical forests around the world decreased, and the small ungulates living in them had to adapt to life in savannas and woodlands, or become extinct. In the process of evolution, some descendants of forest ungulates gave rise to new groups of inhabitants of open areas: this is how fairly large South African animals like deersimil, duicalopes and duikapis appeared. Nevertheless, a part of the population of small ungulates survived in the relict islets of the jungle and evolved in the conditions of a tropical rainforest. Among them was the black duiker (Cephalophus niger), which gave rise to a series of large ungulate species, and the largest of its descendants, njenge, lives in the Neocene jungles of Africa.
In appearance, this species is a large antelope of massive build, a fairly large animal that gathers in herds of 10-15 adults. Besides them, there are cubs and adolescents in the herd. The herd is usually led by a strong adult male, but older individuals rarely leave the herd and can almost always lead other animals to mineral sources or to comfortable resting places.
Njenge’s body length is about 2 m, height at the withers is 120 cm, and the average weight is about 270 kg. It is a relatively short-legged animal that lacks the grace and elegance of plain-dwelling ungulates. The hind legs are slightly longer, so the back is horizontal or the butt is slightly raised. The animal’s neck is short and strong, the horns are thick and heavy, slightly curved, pointing backwards. In older individuals, their tips reach the shoulders. Due to this body shape, njenge can easily move in dense thickets or reeds. Bony protrusions grow above njenge’s eyes; they point upwards and to the sides, protecting the beast’s eyes from grass and branches. The coloration of the animal is peculiar: it combines distinct areas of light reddish-brown and black color. A significant part of the animal’s body is reddish in color, but on the back there is a large “saddle” of black color, extending to the sides. The tail and the narrow area on the back of the beast, as well as the head and the upper part of the neck are also black. Due to this coloration, it is more difficult for a predator to distinguish the outlines of an animal, especially at dusk. A short, erect mane grows on the neck of the beast.
Wide spreading hooves help the animal to move on the muddy ground and swim. Njenge can dive to a depth of 3 meters.
The life of this animal is closely connected with bodies of water, mainly with rivers. Njenge herds are most often found in the basins of Congo-Zaire and other rivers flowing into the Atlantic. It grazes in the morning, evening and during the rain, and spends the entire hot part of the day in the water, lying or standing in water up to its neck. When a predator appears, these animals usually hide in the undergrowth, surround the enemy in a semicircle and meet with horns pointing in its direction. If there is no opportunity to hide, adult animals form a circular defense. Njenges feed on herbaceous plants, but they can also eat foliage, mushrooms and fruits fallen from trees. In general, about half of their diet consists of aquatic vegetation, which they eat along with snails, insects and sluggish fry hiding in it, as well as fish and frog eggs.
A strict hierarchy is formed in the njenge herd, which is broken only when a predator attacks. Fights for the herd most often represent a ritualized display of force: males roar, dig the ground with their hooves and sometimes with their horns, and make feints towards their opponents. Less often, these displays turn into a “power struggle” phase, when both rivals clash horns and butt heads. Young males, who are not yet able to challenge a mature opponent, form separate herds. Among the older males, there are sometimes especially short-tempered individuals living alone.
Njenges mate in the spring. At this time, especially serious fights occur between males, although they usually do not cause injuries. The rate of reproduction in this species is relatively low: on average, the female has offspring twice in three years. Pregnancy lasts 295 to 315 days. Each female gives birth to one, rarely two calves, which are suckled for up to 5 months and reach sexual maturity at the age of two years. At this age, young males are driven out by the leader. Young females may sometimes move to another herd.
The life expectancy of njenge is 25, with a maximum of 30 years.

Widehorn (Pseudosvatherium sylvaticus)
Order: Artiodactyls (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: humid forests of Zinj Land.
Artiodactyls suffered severely during the human era from hunting and habitat destruction, and the Ice Age dealt a blow to the persisting populations of large species. In fact, in the Eastern Hemisphere, after the end of the Ice Age, animals heavier than pigs remained only in Australia. Later, the descendants of the small-sized survived species took a leading position outside Eurasia and North Africa, forming a new megafauna. In the savannahs of the East African microcontinent, or Zinj Land, the largest artiodactyls are goatlopes and horned hogs, and the jungle harbor the widehorn, a descendant of the Holocene Günther’s dik-dik (Madoqua guentherii).
Widehorn is a massive land-dwelling animal, an inhabitant of the undergrowth, feeding at a height of up to 3 meters from the ground. The height at the withers of an adult animal is 2 meters, the length of the body is 3 meters, and the weight is 700-800 kg (males are larger than females). The front part of the body is more massive than the rear part, and the back is sloping. The background wool coloration is gray with white and black markings that break up the contour of the animal: the back is black with “patches” on the front and hind legs; the belly, chest and sides of the head are white, the muzzle and the nose bridge are black. The neck of the widehorn is short, thicker in males; the male has a hanging mane of elongated hair on the lower part of the neck. The head resembles that of an elk, with wide and slightly curved horns. In young animals, the horns are directed upward and backward, in adult and old animals they begin to grow more to the sides. The animal looks like both a nilgai and a lightweight version of the fossil Sivatherium giraffe.
Like its ancestor, widehorn is a solitary territorial animal, with the territories of males and females overlapping. The basis of the diet consists of leaves and shoots of trees and shrubs, and of herbaceous plants. When eating the foliage of trees, widehorns often stand on their hind legs, leaning on the trunk with their hooves. This animal also willingly eats mushrooms and some fruits. Due to the peculiarities of the diet, widehorns rarely visit the watering hole, receiving all the necessary moisture from the consumed vegetation – this is the legacy of their former life in the arid savanna.
Rutting always happens only when there is an abundance of food, most often in the rain season. An agitated male rubs its neck against the branches of some particular trees, leaving secretions of scent glands on them. Skirmishes with other males are rare and usually limited to horn displays and loud roars. Occasionally, males may push each other away from the female with sides and breast.
Pregnancy lasts about 270 days; the female bears only one large, well-developed calf and feeds it with milk for up to 6 months, although since the age of 2 months they begin to feed on herbaceous plants. The calf’s wool is dark, with white markings on the chest and belly. At the age of one year, the young animals are driven out by the female and search for a new place to live. The female brings offspring once every 2-3 years. Puberty in young animals occurs at the age of 2.5 years, but females prefer to mate with large males, so a male can mate no earlier than since being 4 years old. Life expectancy is about 65 years, although most individuals die earlier.

Obiba (Pseudobubalus gigas)
Order: Artiodactyls (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: swampy areas of South Africa.
Artiodactyls, antelopes in particular, suffered quite seriously in the human era due to hunting and habitat destruction. In the temperate latitudes of the northern hemisphere, only few species of this order remained, which allowed the development of hoofed lagomorphs. In the tropics, their diversity is only slightly greater. Perhaps the largest centers of bovid diversity are Zinj Land and South Africa. Large species have mostly become extinct, and Neocene antelopes are descendants of small species. Among the waterbucks (Cobus), some species have survived, and one of their descendants is obiba, a very large semi-aquatic artiodactyl species.
The body length of an adult of this species is about 3 meters, the height at the withers is on average 1.50 m, and the weight is up to 700 kg. The coloration of the thick short wool on the back and sides is brownish red, and chest and belly are white. The neck of the beast is muscled, and the upper spinous processes of the thoracic vertebrae are long – powerful neck muscles are attached to them, which support a heavy load. The horns of this animal resemble those of an Asian water buffalo, for which it received its generic name – they are lyre-shaped, very thick at the base, and their tops in an adult male reach to the middle of the sides. The skull is greatly expanded in the rear; the eyes and ears are shifted to the upper part of the head. The legs are dark brown, with wide rounded hooves capable of spreading apart when walking on marshy ground. The tail is long, with a brown tuft at the tip.
Obiba gives the impression of a more slender animal than bullhog, its neighbor. It feeds on tough graminoids and foliage of shrubs – this reduces competition with horned hogs. Occasionally, these antelopes appear far from swamps and reservoirs in the moist savannah, and when the reservoirs dry up, they gather in the valleys of large rivers, where water still remains. Obibas live in groups consisting of a male, several females and their offspring – on average 10-12 animals. The male protects the group from predators and competing congeners. During an intraspecific conflict, threatening postures and movements are usually enough to resolve the rivalry between two males. In some cases, however, it comes to serious fights, during which horns are also used. Males who are driven out of the herd after such fights live out their lives alone or join groups of young bachelor males. Obibas usually move slowly, however, when running away from a predator, they can reach speeds of up to 70 km/h. In the day heat, they rest in the shade of trees, often enter swamp or a shallow pond. The resting animal sinks almost completely into the water, leaving only part of its back and head with horns on the surface of the water. At this time, not only herons like to rest on their backs, but also birds of prey, for which obiba got its name (sorcerer, literally “friend of the kite” in the Luo language).
Mating takes place in March or April. During the mating season, males are especially inflammable and aggressive: they need to protect their harems from young and ambitious “bachelors”. Pregnancy lasts about 8 months, and one well-developed calf is born. Females take care of their cubs, which are capable of movement in the first minutes after birth. Before giving birth, the females leave the herd for two weeks. It is at this time that they are most vulnerable to predator attacks. At one year of age, young males are driven out of the herd and form bachelor groups, which settle more easily than females, making long marches across the savannah. Puberty occurs at 2 years of age in females, at 3 years of age in males. Life expectancy is about 20 years.

Bald rambull (Pachycephalovis grandis)
Order: Artiodactyls (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: Himalayas, Plateau of Tibet, Altai; mountain woods and meadows at height up to 4 – 5 thousand meters; in the north of area animal goes down, but does not meet in plain regions.
At the boundary of Holocene and Neocene the variety of ungulates had sharply reduced. The reason of it had been mainly human activity/ People had overpopulated the planet and had destroyed habitats of many species. Agrarian landscapes changed by people, where herds of domestic cattle were analogues of wild animals, became the prevailing landscapes in many places of the Earth. After human extinction the majority of domestic animals had also disappeared, but some species able to adaptation, had survived and became ancestors of new forms of Neocene ungulates. Among them there were primitive breeds of domestic sheeps which easily ran wild and became a part of poor communities formed at the place of collapsing agrocenoses. Many descendants of domestic sheeps live in Neocene New Zealand, but separate species had evolved in other parts of the world.
In mountain areas of Asia large artiodactyl – bald rambull is found. Height of this animal at a shoulders is up to 170 cm at body length of about 2,5 m. Externally it is similar to golden goat antelope (Budorcas taxicolor), the original representative of bovids, related to sheeps, lived at the territory of China. The body of rambull is covered with rich shaggy wool of gray-blue color, on back the longitudinal strip of darker wool stretches; the tail is covered with long wool and is similar to horse’s one. Ears are moderately long and covered from external side with wool.
As against New Zealand sheep descendants, bald rambull has almost completely lost horns. Instead of it the upper part of skull at this animal is strongly thickened. The skull of male has the convex top representing a continuous bone outgrowth about 15 cm thick. Males use skull for courtship tournaments during which they put each other strong ramming impacts. Thus the massive cover of skull protects brain of animal from concussion. On top of the head of animal the skin is dense, thick, strongly cornificated, colored dark grey, completely lack of hairs. Near ears of animal there are outgrowths hided in wool, also covered with cornificated tissue – they are rudiments of horns. Females lack of them more often. Also at females the top of skull is not as convex, as at males, and they do not use it for fierce tournaments. Only occasionally females strike each other easy impacts by head, reminding the subordinated individual about their own position in herd hierarchy. Cervical vertebrae are adapted to maintain the sizeable loadings.
The thick ossificated top occupies the most part of volume of skull. The brain of bald rambull is very small, and the behaviour of animal differs in primitiveness. Weakness of sight is compensated, however, by keen hearing and sense of smell, and also by natural care. Animals move across their territory along strictly determined routes, and only natural acts like avalanches or earthquakes force them to search for new ways. This species of ungulates lives in small herds including one dominant male, several females and their cubs of the age of up to two – three years. In herd the not strict hierarchy is established.
Bald rambull eats leaves of undersized trees and bushes. At lack of habitual forage it can eat even branches of coniferous trees. Also the animal is able to dig snow in searches of grass and evergreen bushes. This species lives in conditions of seasonal climate – winter in habitats of bald rambull is frosty and snowy. Therefore right before colds it grows long rich wool of lighter color, rather than summer one.
Pregnancy lasts 11 months; usually the female gives rise to one cub. In favorable years twins are often born – one case to approximately 8 – 10 pregnant females. Cubs are fed on very fat milk and quickly grow. At the age of about 8 months the young animal completely passes to forage of adult animals. At young animals approximately up to one-year-old age the head is covered with wool, as at other representatives of family. At the age of four years animals completely develop physically, and females already can bring posterity. Young male reaches the blossoming of physical strengths to the seventh year of life, and supports this physical condition at least till 15 years.

Sylvammon (Sylvammon gracilis)
Order: Even-toed ungulates (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: evergreen woods of Northern island of New Zealand.
Forests of New Zealand had lost because of human destructive activity large moa birds in Neocene had found new herbivorous inhabitants. Descendants of sheeps, domestic animals introduced to New Zealand became them. In Neocene when the human species had disappeared and set of new ecological niches had appeared descendants of this domestic animal had started to evolve roughly having evolved in conditions of island isolation to some species differing by ecology.
The sylvammon is large species of artiodactyls living in woodlands and forests of New Zealand. Withers height of adult male is up to 150 – 160 cm. By proportions this species is a little similar to deer.
The long neck is covered with mane of lengthened hairs. At old males mane hangs down almost up to knees of forward legs. Shoulders of sylvammon are higher than crupper and back of animal is sloping. Due to such constitution animal can browse leaves from trees at height up to 2 meters. Due to need animal can even rear on back legs. Animal can run quickly and jump high.
Horns are similar to goat’s ones; at females and young males they are straight and only at old males can bend semilunarly. Bases of horns are bulged and also pulled together, and horn tips are directed back – in this case they do not prevent to move in dense wood. Among females hornless animals appear frequently. Horns at males are lighter than at females.
Wool of sylvammon is short and rather thin: animal lives in rather warm climate not rising highly in mountains and not coming to southern areas of New Zealand. Except for mane long hairs grow on tail of this animal more similar to horse’s one. Colouring of body of sylvammon is dark-brown with white stomach and white “glasses” around of eyes.
It lives in woods preferring to graze at sites where bushes and young trees spread off: on marges and near river banks. Frequently it goes to plains overgrown with bush. In wood animals have favourite tracks adhering them at movement.
Sylvammons have kept characteristic for sheeps gregarious habit of life. Herds of these animals total up to 20 individuals and consist of several breeding groups including male and three – four females. In forest herd moves having stretched in line where ahead there are dominant individuals. The rank of females in herd is determined by rank of the male which group they belong.
Due to change of habit of life proportions of animals have changed that was resulted in their behaviour. More graceful constitution has made impossible struggle by ram heads impacts characteristic for ancestors. Males sort out their relations striking each other lateral impacts by head. Crushing blows characteristic for rams were transformed at these animals to demonstration of horns. The sylvammon male shows itself to the contender having bent head down. Thus horns are lifted upwards that visually exaggerates his size. At this time mane on neck of the male is fluffed. Males rear on back legs and can make some steps in such position for strengthening of the impression created at the opponent.
At any season in sylvammon herds it is possible to see cubs. Regularity in breeding at this species is not present but most part of cubs is born in spring (in October – November in Southern hemisphere). One cub usually is born though about a quarter of all females eans twins. Cub is born well advanced as at all hoofed mammals. At one hour after birth it already can walk and at the second day of life does not lag behind herd.

Pacific hapa, tragocampus (Tragocampus thalassocapra)
Order: Artiodactyls (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: medium-sized and small islands of French Polynesia.
In the age of man, many domestic and feral goats lived on various islands of French Polynesia. The activities of these animals, unchecked by humans, led to an environmental disaster. The animals destroyed the vegetation of the islands, and either died out, or adopted a new way of life for their own survival – they switched to eating seaweed. In many cases, such a harsh natural experiment led to the extinction of populations of descendants of domestic goats, but in one case it nevertheless proved successful, and in Neocene on medium-sized and small islands, where there were no large terrestrial predators, a new species evolved: a small gregarious omnivorous semi-aquatic animal – hapa, or tragocampus (hapa – “goat” in Tahitian, tragocampus is from the Greek τράγος – goat and κάμπος – sea monster).
Hapa is to some extent an evolutionary analogue of the Galapagos beach boar, which evolved on the other side of the ocean. It is an omnivorous animal that feeds on island herbaceous vegetation, but a much larger part of the diet of this species consists of seafood: algae, beached fish and invertebrates, including those with shells, which hapa masticates easily. These animals can also feed on the eggs of birds and turtles. These goats are able to scrape algae from the reef surface with their teeth. Hapas also willingly eat the leaves of aquatic flowering plants.
Such a lifestyle atypical for bovids has left a deep imprint on the appearance of the animal. It is a small animal of massive build (slightly resembling a miniature cow with an elongated body) having a pronounced sexual dimorphism. The largest male reaches 70 cm at the withers, and the female reaches 50 cm. The animal has a massive body with a developed layer of subcutaneous fat and relatively short legs with widely spreading hooves. The weight of the largest tragocampus male is up to 50-60 kg. Isolated populations of smaller sizes, weighing no more than 30 kg, are found at the edges of the range.
Females have almost no horns; males have horns that reach a length of no more than 15 cm, being thick, slightly curved and triangular in cross-section. The hair covering is normally developed, short, but thick. Males are dark brown in color with white “socks” and white tail; the back is darker than the sides. Females are light brown with a dark back, also with white “socks” and tail. The hooves have sharp, hard edges that allow walking on the reef surface at low tide, and there is a small skin membrane between the digits for easy swimming. The front hooves are often used to dig up the bottom soil. Hapa swims by paddling its feet alternately or using a “galloping” style of movement.
Due to its large, complex kidneys, hapa can drink seawater without any harm for itself. The animal is able to swim continuously for 6-8 days, resting on the water surface due to a layer of subcutaneous fat. In this way, separate animals settle to other populations or to previously unsettled islands.
Hapa has a head on a relatively short neck, with a narrow deep muzzle and nostrils that can close by skin valves. Hapa can stay underwater for up to 7-10 minutes and dive to a depth of about 15 meters. The lips of the animal are mobile, with corneous brushes on their inner surface, well suited for holding and tearing off leaves and algae thalluses. The ears are short, equipped with a skin flap closing the ear canal. The animal orients itself underwater with the help of vision; its eyes are relatively large, with a narrow horizontal pupil, which expands greatly under water.
The smaller the island and the poorer the food resources, the more time hapas of the local population spend in the water. They graze in the thickets of underwater plants of Dendronajadaceae family, eat macroalgae on reefs, and also hunt all living things that they can catch in the water – usually crustaceans and mollusks.
These animals live in herds under the rule of a dominant male: the herd represents a harem of his females and offspring of various ages. Males almost do not fight for females; the rivalry ends with a display of horns or underwater thrusting into the opponent’s side. In a particularly fierce fight, males bite each other. On the shore, tragocampus males with horns of the same size can butt heads for a couple of minutes, but they do it very clumsily because of their massive physique.
Once a year, after the rainy season, the female brings from one to two (very rarely three) small yeanlings. They are well developed, by the end of the first day of life they run, and after a couple of days they are already able to swim. Females become sexually mature after 1.5 years, and males after 2 years. Hapa lives 10-15 years, the largest males live up to 20 years. The main enemies of this species are sharks that hunt in the coastal waters. Occasionally, animals die during a storm, tossed on a rocky shore.

This mammal species was discovered by Wovoka, the forum member.

Great goatlope (Gravicaper magnus)
Order: Artiodactyls (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: Zinj Land, savannas and light forests at the west of subcontinent.

Picture by Alexander Smyslov

In human epoch ungulates of bovid family had suffered the great damage. Many of their species had been objects of hunting, and practically all wild species had suffered from destruction of inhabitancy and the expansion of territories occupied for agriculture. Subsequently the significant part of these grounds had undergone to desertification, and began even less suitable for life of ungulates. In Neocene new groups of running herbivorous mammals had appeared, and the variety of ruminant artiodactyls had reduced. In human epoch herds of various wild ruminants were replaced by monospecific herds of domestic cattle which had become extinct after people in the majority of places. But representatives of primitive breeds of domestic ruminants became ancestors of some species of Neocene ungulates. At the East-African subcontinent (Zinj Land) from feral domestic goats many kinds of goatlopes had descended; these ones became dominant herbivores of subcontinent alongside with horned suids of Porceratidae family.
In savannas at the west of Zinj Land small herds of very large ungulates similar by a constitution to domestic humped ox or eland antelope of human epoch graze. It is the most massive representative of goatlopes, the great goatlope. Its genus name “Gravicaper” means “heavy he-goat”, and emphasizes features of its anatomy. Evolution of goatlopes directed to increasing of body size is limited by presence of large horned suids at Zinj Land. In Neocene among suids a plenty of massive running forms occupying ecological niches of rhinoceroses, tapirs and bulls had appeared. Therefore great goatlope is an only exception among swift-footed gracile relatives.
Great goatlope is an ecological analogue of elands of Holocene. Growth of this animal at a shoulder is about 160 cm, and weight is up to 800 kgs. Legs are rather short, and hoofs are wide. Front and rear legs have approximately equal length, therefore back of animal is horizontal. Great goatlope runs rather slowly and prefers to live on plains with firm ground.
The large animal in conditions of a hot climate faces with a problem of heat emitting. At great goatlope on the neck “hanger” develops – wide plica of skin stretched from chin up to back edge of thorax. This skin is penetrated with blood vessels, and in day heat they dilate, giving to air surplus of heat.
Skin of great goatlope is covered with very short light grey wool; from apart its wool seems velvety. At young animals wool is rather long and darker, rather than at adults. At adult animals long black hair growing on the bottom edge of “hanger” form a kind of “beard” from chin up to stomach. It is especially well advanced at males and helps to estimate force and physical condition of the male in courtship season. On long tail there is a switch of black hair.
At great goatlope both females and males are horned. Horns of these animals are short and have wide bases almost adjoining on forehead. Horns are lyre-shaped, and the annual gain adds new relief ring in their basis. During courtship duels males fall on knees of forward legs and combat, striking impacts by head and neck. Rut at great goatlope takes place at the beginning of dry season.
Great goatlope eats lower parts of grasses and undersized plants, therefore it prefers to graze near to other species which eat top parts of plants. This species does not compete to bikifaru, the representative of horned pigs, because it occupies various habitats, preferring dry ones: savannas overgrown with grass and flat hillsides with small amount of bush.
Once a year, in the beginning of rainseason, the female gives rise to one large, well advanced calf. One hour after birth it already can walk, and at the second day of life it runs on a level with adult animals. Sexual maturity at these animals comes at the age of 3 years.

Donkey goatlope (Hippocapra asellina)
Order: Artiodactyls (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: Zinj Land, savannas and woodlands at the west of subcontinent.
Goatlopes evolved at Zinj Land are descendants of the common ancestor, domestic goat (Capra domestica). Till the evolution history, occupying various habitats, these animals changed, adapting to new conditions. It allowed them to avoid competition and to use resources of an environment more effectively.
The highest species of goatlopes is donkey goatlope living in dry regions at the west of subcontinent. Its growth at a shoulder reaches 170 centimeters, and animal can browse branches at height more than 2 meters. This is quickly running animal of gracile constitution keeping in large herds.
Donkey goatlope is easily distinguishing due to the specific colouring similar to colouring of Grevy’s zebra (Equus grevyi) lived in human era. But the colouring of this species is less contrast: on body, shoulders, hips and neck on light greyish-beige background thin and dense vertical brown strips stretch. At old animal strips on back part of body may turn pale. At young growth colouring is more contrast, and calves of this species seem darker. The bottom part of legs at animals of any age is single-color greyish-white. For recognition of congeners donkey goatlope has dark marks on head: wide black strip at the edge of ears and black top part of head.
At this species horns are present at animals of both genders. They are lengthened, twisted as at koodoo antelope, and have smooth surface. At males horns are larger, rather than at females.
Tail of donkey goatlope is similar to horse’s one – it is short and covered with long white hair.
Distinctive feature of this species of goatlopes is long ears. This is an adaptation helping to be cooled. At donkey goatlope the special form of social behaviour is developed: as a sign of attachment to each other animals lick each other’s ears; the female also behaves so in relation to the calf. This ritual has practical value: saliva evaporates, improving heat emitting. Besides on cheeks of animal wide lobe-like hangers. If the animal becomes hot, blood inflows to them, and they increased in size, also emitting heat in air.
Due to high growth donkey goatlope does not compete to other species of ruminants of Zinj Land. It eats top parts of graminoids and foliage of bushes, and can browse bottom branches of low trees. Therefore more often it lives at edges of small forests and thickets of bushes. This species keeps in herds including both males and females. Such herds may total some tens animals of various ages. Out of courtship season males are tolerant relatively to each other. In courtship season, which begins at the end of rainseason, they start to behave aggressively to each other, and the herd is separated into set of harems, each of which is jealously protected by male. At this time males start to emit very strong “goat” smell. Males battle against each other, having widely moved apart front legs and having lowered heads. The winner male drives defeated male away from harem, uttering throat bleating, and brings its females in harem. At this moment it starts to smell especially strongly. Male of donkey goatlope “marks” females by original mode – he urinates plentifully on the ground, rolls in dirt, rubring urine in wool, and then rubs against females, leaving smell of urine on them. During courtship season male repeats this procedure each day.
At the beginning of the next rain season the female gives birth to one well advanced calf. In first some minutes after birth it already rises on legs and tries to walk. At the age of three months vegetative food contains more than half of its diet. The female, in addition to milk, feeds calf with belched semidigested grass, thus supplying it with unicellular organisms necessary for life, which live in stomach at all ruminants.
Young females become sexually mature at the second year of life, and males at the third year. Life expectancy of these animals in nature does not exceed 20 years.

Swamp goatlope (Paludicapra pseudositatunga)
Order: Even-toed ungulates (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: Zinj Land, marshlands in east and southeast of subcontinent.

People left after them the impoverished and broken ecosystems, and also a significant amount of feral domestic species of animals. During the restoration of ecosystems, in first millions years after disappearance of mankind, till the process of adaptive radiation many new species of animals occupying various ecological niches have appeared. It reduces the competition between them as such species though related to each other, differ in requirements to inhabitancy and can coexist in the same territory, using different food sources.
In East African subcontinent (Zinj Land) in Neocene the various bovids live; they are goatlopes, descendants of feral domestic goats. Various species of these animals differ in size, constitution and features of inhabitancy. Many species of goatlopes inhabit open landscapes with firm ground, but one species, swamp goatlope, has developed life in marshlands at the east of subcontinent.
Swamp goatlope is “antelope” of gracile constitution; growth of animal at a shoulder is about one meter. The wool of this animal is short, colored reddish-brown with thin vertical strips of white color – such pattern helps this animal to mask in reeds. At male long beard grows, females have only bunch of hair on chin. Both males and females have long skin “wattles” on lower jaw. At males ducts of specific glands secreting characteristic goat smell open in them: oily secretions are rich in caprylic acid and serve for marking of territory and recognition of congeners. “Wattles” of males are covered with long wool which absorbs secretion and keeps smell during long time. At meeting animals sniff each other’s “wattles”. To make marks at the border of territory male rubs “wattles” against tree trunks and reed stalks.
Swamp goatlope is able to swim and walks confidently in fenny places. On fenny ground fingers and toes of animal move apart, increasing the area of support. Hooves of marsh goatlope are long and wide, therefore it runs rather slowly overland. Beyond the shelters swamp goatlope feels like uncertainly and prefers to not appear in such places. But in reeds this animal lays a network of footpaths on which it moves across its territory. The part of footpaths is directed to shelters – to rich thickets and to swamps overgrown with floating plants where it is difficult for predator to pursue this animal.
Horns of marsh goatlope are pointed and long. They are similar remotely to horns of oryx antelope (Oryx), but are not acute and conic, and twirled as a dense spiral along an axis. This animal lives in herds including several tens of individuals of both genders. Beyond the breeding season male behave peacefully to each other, but in heat time there is a strong competition between them. Males of this species fight, hooking each other’s horns, and struggle, having kneeled forward legs.
At female two calves are born almost always. Only young females give rise to one cub, and in one case from ten even triplets may be born. But usually one calf from triplets quickly dies, because it does not get enough milk. Calves differ from adult animals in darker colouring – at them white strips are narrow, and background color of wool is brown. Young animals pass to diet of adult animals at the age of 4-5 months and remain in parental herd up to sexual maturity (at the age of 22-25 months).

Longhorn goatlope (Laticornella frontalis)
Order: Even-toed ungulates (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: Zinj Land, savannas in the north and west of subcontinent.
During the adaptive radiation in Zinj Land a plenty of goatlopes appeared – these ones are descendants of feral goats which have occupied various ecological niches in nature of subcontinent. Species of goatlopes adapted to various habitats differ from each other in size and constitution. Adaptive radiation reduces a competition between them and allows using of resources of inhabitancy more effectively.
Herds of herbivores in dry plains of Zinj Land are formed by various goatlopes and cursorial descendants of pigs - large bikifaru (Dilophoporcula rhinocerotoides). Among them representatives of original species of goatlopes, longhorn goatlopes, are remarkable in their special appearance. Females of this species look rather usual, but male horns differ in original shape having analogues only at some prehistoric species of ungulates.
The height at a shoulder of adult male of longhorn goatlope reaches 150 cm; females are smaller a little. This animal has gracile constitution, slightly sloping back and rather long neck. This species of animals is adapted to fast running: despite of great size, longhorn goatlope can accelerate momentum about 70 kms per hour at the short distance.
At this species sexual dimorphism is sharply expressed. The female of longhorn goatlope is hornless; its wool has grey color with numerous cross strips on legs and crupper. Stomach is white; between area of white wool on stomach and background colouring wide black strip stretches. Eyes of longhorn goatlope female are surrounded with area of white wool which at different individuals varies from small crescent spot at back edge of an eye up to wide irregular-shaped ring. Beard at female is small and grows only on lower jaw.
Male of this species has darker colouring – it has wide cross strips on legs and crupper, and on body there are scattered numerous black spots on grey background. Head of male has appreciable black-and-white colouring: back part of head, area near ears, nose bridge and cheeks are black, and the tip of muzzle, lips, beard, lower jaw and area around of eyes are white. Beard at males is more advanced, rather than at females: it grows on lower jaw and strethes back up to throat.
Males have long horns of original shape – hence the name of species. Span of horns reaches almost 2 meters. They grow in sides and are curved upwards a little. At old individuals horns are slightly bent back. Such horns can not be used as the effective weapon against predators, therefore at predator attack males of longhorn goatlope rely only upon their own speed. In courtship season duels of males have exclusively ritual character – males fall on knees of front legs and “measure” the length of horns, only slightly touching each other by forehead and touching each other’s horns. In such duels animal with the longest horns wins though occasionally male, at which one or both horns are broken, may win due to larger size. At males and females of this species forehead is wide, and frontal bones of skull are thickened a little.
Because of special shape of male’s horns longhorn goatlopes avoid woody areas and the regions overgrown with high bushes, preferring grassy plains. They keep near to herds of larger goatlope species, avoiding thus attacks of predators. Due to high growth, keen sense of smell and good sight they can notice approaching of predators in time, and notify animals surrounding them on danger with loud bleating.
Usually female gives rise to one calf; twins are born approximately in quarter of the general number of birth cases. Calf is well advanced, able to run in one hour after birth. It has spotty colouring which helps to mask in grass. As they grow, young females loose spots on body, and on legs color marks merge to strips. At males juvenile colouring is partly kept – only the part of spots vanishes. At the age of 2 years females already can take part in breeding. Young males also reach sexual maturity, but usually they can not compete to older congeners. At the age of 5 – 6 years male’s horns reach the size typical for this species.

Crested goatlope (Sylvicaprella sylvana)
Order: Even-toed ungulates (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: Zinj Land, humid forests in east and southeast of subcontinent.

After human disappearance some species of domestic animals had an opportunity to evolve on a par with wild species. Primitive breeds of domestic goats, widespread in tropical areas of Old World, not too dependent on people care, had been among such animals. In Zinj Land descendants of these animals had evolved to some species of goatlopes of various sizes, differing from each other in shape and ecology. Large species of these ungulates are inhabitants of plains, and small species, which growth at a shoulder does not exceed 30 cm, live in tropical forests at eastern coast of subcontinent.
One species of small goatlopes is crested goatlope widely settled in the east of Zinj Land. It is an original ecological analogue of duikers, dwarf antelopes known in human epoch. Growth of this animal at a shoulder is about 35 cm. In its constitution this goatlope is similar to duikers or shevrotains – it has rather short legs allowing run quickly in underbrush and sharp changes of run direction, when escaping from the enemy. Neck of this animal is also short, and head is prolonged and has wedge-like shape and mobile lips allowing feeding on leaves. The feeding animal frequently rears on two legs and can keep such position of body at feeding for a long time.
Wool of crested goatlope has camouflage colouring – on head, neck and sides it is grey with olive-green shade. From nape along the back black strip stretches, faltering sometimes. It reaches a tip of tail. The bottom part of tail and back part of buttocks are covered with white wool. In case of alarm fluffed up wool of tail lifted upwards is an alarm signal. On head between the bases of horns the long bunch of rigid white wool grows, well visible from apart. Using it, crested goatlopes notice congeners in twilight of tropical forest underbrush.
Horns of this animal are straight, pointed and short; their tips are partly directed in sides. Protecting itself against enemy, animal makes deep chipped wounds by horns. Males of this species, establishing hierarchy relations, butt each other. Crested goatlope lives in herds including 10-20 animals under leadership of older male. They frequently form mixed herds with local flightless birds – dwarf ostrich species. It allows representatives of both species to watch world around – crested goatlope has sharp hearing and sense of smell better, and dwarf ostriches have wider field of view because of the growth.
The courtship season of this species is very long, and during half-year there are the females ready to pairing in herd. Males compete to each other for an opportunity of pairing, and dominant male appears the father of calves born in herd in most cases. Barchelor males live lonely or in small groups. Because there are no females near them, they relate to each other much more peaceful, rather than in common herd.
Usually female gives rise to one calf though about one third of females can give rise to twins. Pregnancy lasts till about two months, and calves are born two times per one year at the same female. Calf differs from adult individuals in darker colouring with irregular-shaped cross strips. White marks appear at the age of 16-18 months when young animal reaches full development and can take part in breeding. Life expectancy of crested goatlope does not exceed 15 years.
In tropical forests of different areas of the Earth some animal kinds very similar to crested goatlope have appeared. In forests of Mauritius dwarf dryocaprella lives, descending from the same ancestor, but not related to this species, and in Great Antigua Island, there is a cursorial mazamara rodent, which is only convergent similar to this species. Similar conditions had independently resulted in formation of similar features of anatomy at these species.

Antilopine Forest Buffalo (Bubalotragus sylvanus)
Order: Even-toed ungulates (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: Tropical rainforests of northern Meganesia.
Among the mammals introduced to Australia by man, it is the ungulates that have become the most successful during the Neocene. In the north of Meganesia, descendants can be found of deer, pigs and water buffalo. Some descendants of the water buffalo became analogues of hippopotamus, but others stayed closer to the original bovid body type.
The Antilopine Forest Buffalo has lost the stocky body shape of its ancestor, and looks almost like a forest antelope; it is a graceful browser which reaches 1.5 meters at the shoulder and a weight of about 300 kilograms. Legs are relatively long and slender, and the neck is of medium length, it browses on low and mid level vegetation, mostly the leaves of trees and bushes, as well as bark and fallen fruit. Sometimes it will use trails cleared in the forest by other animals in order to feed, and it will frequently venture into clearings and forest margins for the same purpose. The profile of the head is more graceful and antelope-like than its ancestor, with a tapering snout, horns are of medium length and spiral weakly, very sharp, and shaped like a backswept lyre. Pelt is a coat of short hair much like that of a horse, which is dark reddish brown, extremities of the legs and the base of the snout are whitish, ears are large like a cow, with blond “tassels” of hair, the tail is long and ends in a blond tuft.
Individuals lead mostly solitary life, males are completely solitary but females and young may congregate occasionally in small groups. This bovid is mainly crepuscular, being most active at dawn and early morning, and again at late afternoon and dusk. They are generally shy and will mostly flee danger, but can retaliate with their horns to fearsome effect if provoked. Males will spar and display to each other with horns when they come across one another, and they only seek out the females during the breeding season. Disagreements among males over females are generally resolved with sparring and posturing, rarely do fights take place. Mating is during the dry season and the female gestates for 10 months, a single calf is born that is weaned at 6 months, young reach sexual maturity at 2 years. Calves are kept in hiding in a special spot in the undergrowth for up to two weeks after birth, until they are strong enough to follow their mother. Though mostly silent, the call of this animal is partway between a moo and a bleat, or a nasal snort. The young are preyed upon by the marsupial panther and yagil, but the adults are generally well defended and large enough to avoid predation. Lifespan is up to 20 years.

This species of mammals was discovered by Timothy Donald Morris, Adelaide, Australia.

Lembu or Bornean false buffalo (Pseudotaurus lembu)
Order: Even-toed ungulates (Artiodactyla)
Family: Bovids (Bovidae)

Habitat: tropical forests of Indonesia (Borneo Island).
In Neocene feral descendants of primitive breeds of domestic goats (Capra domestica) appeared the most successful survivors among bovids. They easily adapted to new habitats and evolved in various directions to increase their biological diversity. Lots of goat descendants inhabit Zinj Land – East African microcontinent splitted from African mainland. Island part of South East Asia is another center of their biological diversity, while the mainland is inhabited by large herbivores of other families – bulldeer and thunderhorns.
Lembu is the largest mammal of Borneo Island. The name “lembu” means “bull” in Malay language, and the appearance of this animal justifies this name.
Lembu has deep and narrow body, long legs and a humped back; hump is more expressed in males. Horns of females are short and tightly curved, pointing inward at the tips, while those of males arc upwards, growing 60 to 75 cm long. Spinous processes of thoracic vertebrae represent a support for muscles that move male’s large head. Male lembu has a head-and-body length of 240 to 310 cm, while the females have 210 to 230 cm. Adult male is dark brown, approaching black in very old individuals; the upper part of the head, from above the eyes to the nape of the neck, is white; muzzle and lower parts of legs are also white. These marks help animals to recognize each other in forest gloom. Females and juveniles are chestnut with the same white parts as at male. Wool is short, but on lower jaw a beard of elongated wool grows at males and older females. Tail is short, covered with elongated hair forming a tuft.
Both males and females have paired leathery lobes on necks helping them to remove an extra body heat. Flesh of these lobes is penetrated densely with blood vessels, and when animal is overheated or excited, these lobes swell with blood and elongate. Sometimes animals mutually lick these lobes to each other as a sign of good relations between them.
These animals feed on grasses, young bamboo shoots, fruits, leaves and young branches. Being active both at night and day, lembu pastures in the open areas at night and under the forest cover during the day.
The herd is led by an old adult female, the matriarch. Herds number up to 20 individuals, generally females and calves, but males join them during the dry season. Older males are solitary, but the young ones form bachelor herds.
After 278 days long gestation female gives birth to one calf. Calves are typically weaned after seven to 12 months. Sexual maturity occurs in the second or third year of life. Breeding takes place year-round. After reaching maturity, the males are expelled from the herd. The usual lifespan reaches 30 years.

Four Horned Phobocorn (Quadrucornis armatus)
Order: Even-toed Ungulates (Artiodactyla)
Family: Bovids (Bovidae); subfamily: Phobocorns (Phobocorninae)

Habitat: Scrub and broad-leaf forest of eastern Madagascar.
During the beginning of the Neocene, some animals evolved into shapes and niches seen previously in other animals. Less often, completely original forms appeared, exhibiting features not seen in wild animals before. Some original groups became entirely new kinds of animal, one such group is the representatives of Phobocorninae subfamily.
Descended from run-wild domestic goats, these horned ruminants are in many ways unremarkable. Their bodies and coloration resemble small and medium sized antelopes of various kinds, such as impala or sitatunga. Their plain appearance stops, however at the horns, a hallmark of their ancestors, greatly enhanced.
Phobocornines are defined by the presence of more than one pair of horns. Such arrangements of horns had been rare in human era, present only in the Tetracerus antelope, and some breeds of sheep. There are some genera, each having different horns respectively, four or six, in various arrangements and sizes.
The four-horned Phobocorn, posses fairly impressive horns, 2 pairs, growing from the brow, behind the eyes. One pair inclined upwards, the other down, in this way, they resemble four-horned domestic sheep breeds of human occupation. The horns have widely spaced ribs, and are slightly curved, and are only slightly shorter than the length of the animal’s head. Unlike some other Phobocorns, there are no horns on the base of the nose. Four horned Phobocorns are medium-sized browsers of the forest thus having dark brown pelts with lighter vertical tripes, similarly to some Holocene antelope, aiding in camouflage. In size, they are equal to a medium sized antelope, like the sitatunga: the shoulder height is about 130 cm at weight of about 140 kg.
Like all Phobocorns, breeding occurs in the wet season. At the middle of dry season males display lekking behavior, with males competing physically by ramming foreheads, and poking each other in sides with horns. Females give birth coinciding with the flush of growth in the later part of the wet season.
Related species Lesser Four-horn (Quadrucornis minor) inhabits sparse forest on the Western side of Madagascar, and is also a browser. This one is mostly similar to its larger relative, except for lighter coat color, body slightly smaller (shoulder height is about 110 cm). Horns are not equal in size, outer pair are half the length of the top pair, unlike eastern relative. It is relatively uncommon, due to the presence of more successful Six Horned Phobocorn.

This species of mammals is discovered by Tim Morris, Adelaide, Australia.

Western Dwarf Phobocorn (Neotetracerus dimorphus)
Order: Even-toed Ungulates (Artiodactyla)
Family: Bovids (Bovidae); subfamily: Phobocorns (Phobocorninae)

Habitat: Scrub and savanna of western Madagascar.
Dwarf Phobocorns are the smallest of the Phobocorns, and are mixed feeders on both low browse, herbage, and soft grasses in scrub-land and grassland. They posses smooth, short horns, one pair of typical brow horns, non spiraling, and one smaller pair projecting from the base of the nose, in front of the eyes. In this way they resemble the Indian Four Horned antelope of human era. Males have both pairs of equal length, but females have the front pair larger, and the posterior pair relatively smaller. This is connected to the fact that males use their horns in territorial and lekking disputes with other males, but females must use their horns to defend themselves and their young. These animals are about the size of a miniature domestic goat, but more slender, possessing tan pelts with a darker stripe down the back, the muzzle and eye area are darker. Males joust and lock horns actively, competing for females. As with all phobocorns, breeding occurs in the wet season. Young are relatively small, and will hide in long grass similarly to a deer fawn.
Upland Dwarf Phobocorn (Neotetracerus montanus) inhabits the plateu and mountain slopes of central Madagascar, and is adapted to eat the tougher plants of upland scrub and savanna. It is lightly colored, cream, with slightly darker patches hardly discernible, dorsal stripe is paler than plain relative. Body and legs are stouter, and the animal is quite surefooted.

This species of mammals is discovered by Tim Morris, Adelaide, Australia.

Pied-horn Phobocorn (Cincatocornus ornatus)
Order: Even-toed Ungulates (Artiodactyla)
Family: Bovids (Bovidae); subfamily: Phobocorns (Phobocorninae)

Habitat: Grassland and sparse forest of western Madagascar.
The Pied-horn is a rather beautiful animal. It is pale greyish brown, with dark "socks" on its lower legs, and light markings around the face. It has 1 pair of long upward-backward pointing, spiral horns (like those of the holocene Blackbuck antelope), in the typical place. There is also a smaller pair of horns at the base of the nose, just before the forehead. The front pair are ivory colored with black tips, whilst the larger pair are banded in black and white, creating a striking appearance. Both males and females will use horns for defense against predators, sometimes simply posturing with horns is enough to deter attackers. This creature is about as large as a ram, with slightly longer legs. It is a commonly seen grazer and only browses rarely, in times of famine. Horns are arranged in such a way as to not impair vision when the animal is grazing.
The Pied-horn is the most common and populous of the Phobocorns, forming large herds. As might be expected, males do not joust or ram with such ornate horns. Males simply posture and show horns, with elaborate head-sweeping motions, males with most impressive horns generally win. Females give birth when the grass is lush and green, at the end of the wet season, young are almost immediately able to follow the herd.

This species of mammals is discovered by Tim Morris, Adelaide, Australia.

Six Horned Phobocorn (Phobocornis apocalypticus)
Order: Even-toed Ungulates (Artiodactyla)
Family: Bovids (Bovidae); subfamily: Phobocorns (Phobocorninae)

Habitat: Open Forest, scrub, treed savanna, western Madagascar.
The most impressive phobocorn, truly a sight to behold. It is the size of a pony, thus, the largest Phobocorn. So named for its uncanny resemblance to the biblical multi-horned goat, harbinger of the Christian apocalypse.
This animal is colored ruddy brown, with faded greyish brown stripes, a light underside, and white "socks". It possesses 2 pairs of large, ribbed brow-horns, and a smaller pair of horns on the forehead. Paired horns are back-swept so as to not interfere with feeding. Males and females have horns of similar size, but males posses a "beard" of whitish hair on the neck and lower shoulders.
This phobocorn is a generalist, mixed feeder, and has a large, chambered stomach. Able to consume leaves of broadleaf trees or bushes, twigs and shoots, as well as both soft and coarse grass. It derives some of its water consumption from succulents, and will depend on them more heavily during the dry season, when trees drop their leaves.
Breeding behavior is during the wet season, males use horns in competing for females, but fighting is mostly ritualized. Horns lock, as with deer, and each male tries to push the other's head to one side. Young are fairly large, and move from suckling to regular browsing fairly quickly, but start with the more tender parts of bushes and low trees.

Duikapi (Giraffotragus altus)
Order: Even-toed ungulates (Artiodactyla)
Family: Bonehorns (Osseocorni seu Parabovidae)

Habitat: savannas and light forests of Southern Africa.
After the ice age of boundary between Holocene and Neocene borders of some zoogeographic areas have changed. So, after Mediterranean sea drying and Gibraltar isthmus formation border of Holarctic zoogeographic area has moved to the south having included the north zone of African savannas (the middle Sahara watercourse of Niles (flowing now from the east to the west of Northern Africa and inflowing to headstream of Niger river) serves as border between Holarctic and Ethiopian zoogeographic areas). In Northern Africa there are descendants of Eurasian and Near Eastern animals and small impurity of descendants of African forms. But in Southern Africa separated from the north by continuous zone of mountains and marshy woods stretched along the equator relicts of a Holocene have remained and evolved - various species of even-toed hoofed mammals, descendants of different African antelopes. They occupy different ecological niches and are not less various than species of antelopes in early historical epoch.
Among herds of new South-African antelopes grazing in dense grass giants sedately wandering by small groups and regaling themselves with soft leaflets of trees inaccessible to anybody from other hoofed mammals are especially remarkable. These giants of Africa are duikapi – descendants of one species of the African wood duiker antelopes (Cephalophus). Though ancestors are too small, their descendant is rather large herbivore mammal: its withers height is up to 170 cm at body length up to 2 meters. Neck of duikapi is very long (the common growth of animal from horns up to hoofs is almost 3 meters). Colouring of short animal’s wool is sandy-yellow with brown cross strips on legs and neck; back is dark. Cubs of duikapi seem darker than adults: on their body strips are narrower and denser.
These long-legged animals move with amble similarly to giraffes and camels. In case of danger they can run gallop accelerating momentum up to 50 kilometers per hour.
Skull of adult animals is strongly bent in middle part; large eyes and small brain cavity tower above the lengthened obverse part. Due to high position of eyes at these animals there is fine circular field of view and they notice predators from afar. Similarly to giraffes and ostriches in Holocene epoch savannas duikapi serve as though as “sentinels” for other herbivores. Large nasal cavities indicate that at duikapi sense of smell is very keen.
On nape of duikapi the original cross wide “horn” is developed covered with wool and doubled at top where reduced rests of true horns, two small horn knobs are placed. Such bone ledge is used as the tournament weapon: contenders approach to each other by chest, rest foreheads and “struggle” by heads trying to curve neck of the opponent to force it to refuse struggle and to recede. Such fight is the original compromise between natural habit to butt inherited from bovine ancestors and rather fragile constitution of duikapi.
Duikapi keep in groups of 5 - 8 animals under the leading of elder female. In such group there are some adult females and their under one year aged cubs. Elder young males abandon mothers and young females can remain in parental group or leave it and create own one. Males live solitarly or in groups of 2 - 3 animals. Out of breeding season they tolerantly concern to each other but in breeding season their aggression relatively to each other sharply increases.
Duikapi are out of competition among animals of South-African savannas and light forests. These high animals browse branches of trees and bushes inaccessible to their neighbours. If all accessible lower branches on tree are eaten duikapi easily can rear on back legs resting hoofs against tree trunk and reaching up to fresh branches.
Pregnancy at this species lasts about 6 months. At the female only one cub is born at the end of dry season. Growth of newborn cub is about one and half meters. First time it feeds exclusively by milk but from monthly age gradually passes to vegetative food. It stops to depend on mother at the age of half-year, and becomes completely adult at the third year of life.

Thick-horned thunderhorn (Brontocornus magnus)
Order: Even-toed ungulates (Artiodactyla)
Family: Thunderhorns (Brontocornidae)
Habitat: Hindustan, South-Eastern Asia, woodlands, bushes, foothills.

In human epoch representatives hoofed mammals had a hard time. They appeared among favourite game, number of many species had strongly reduced, and some of them had disappeared at all as a result of hunting or change of habitats. The ice age had finished this epoch appeared one more test for them. Many species at this time had disappeared and variety of hoofed mammals had sharply decreased. Some orders like proboscid and sirens had disappeared completely. Therefore in Neocene hoofed mammals are presented by not numerous isolated families. But their evolution was not finished - survived groups of animals evolved to descendants perfectly adapted to changed inhabitancy.
In India separated from other Eurasia by Himalayas the whole new family of even-toed mammal had appeared. Its representatives differ in various form of horns turned to resonators for strengthening of voice. Because of this feature animals had been named “thunderhorns”. They descend from bovines, obviously from any small antelopes. Cavities of bovine horns had joined frontal and nasal cavities. At thunderhorns, their descendants, these cavities had got more complex form and horns had turned to resonators. At different species of these hoofed mammals resonators have various shape and voices of these animals differ appreciably. The voice serves for recognition of species representatives in bushes at a great distance (all thunderhorns are inhabitants of forests and bushes). One more role of loud voice is to inform the probable contender that any territory is occupied and by that to avoid force methods of struggle. Resonator outgrowths are rather fragile ones, also they are unsuitable for force struggle. In this connection the horn cover on these outgrowths at different species is at different stations of reduction up to its full disappearance. Females at all species of thunderhorns have fewer horns than males.
Thick-horned thunderhorn, the central representative of family, has kept more primitive ancestral features than other species. Its horns are similar to strongly swollen and short ram horns having kept horn cover on the top side. The voice of the present species resembles roar of any predator.
Thick-horned thunderhorn is small deer-sized animal differing in graceful constitution. The basic colouring of wool is light brown. Neck, back and rear legs of animal are covered with short black cross strips forming fine cryptic colouring. On legs black wool forms “stockings”. Tail is white, on the bottom side of neck also lengthened white wool grows. Tail put upright means signal of danger.
This animal keeps among bushes feeding by leaves and grass.
Thick-horned thunderhorn does not form herds and keeps in “harems”: one male and 4 - 6 females. In breeding season between males duels take place accompanying with loud frightening roar audible for kilometer and more. The rut falls to the beginning of dry season. Pregnancy lasts about 5 months. As a rule, female gives rise to one calf colored similarly to adults but having longer strips. At the age of one year young animals leave parental herd and form their own herds. Sexual maturity comes at three-year age (at females it happens some months earlier, than at males). At this time herds of young animals separate to harems. Life expectancy in nature reaches 12 - 14 years.

Forest trumpeter (Buccinotherium magna-voce)
Order: Even-toed ungulates (Artiodactyla)
Family: Thunderhorns (Brontocornidae)
Habitat: Hindustan, foothills of Himalayas, light forests and thickets of bushes.

This species is large hoofed mammals of heavy-build constitution, one of the largest representatives of family: withers height of the adult male reaches 2 meters, female is a little bit smaller. The skull of this species is rather long; more than half of it the hollow resonating crest of the roundish shape amounts. Horn covers have completely disappeared and remained bases of horns are covered with velvety wool and rather brightly colored. The crest is high, compressed from sides; its edge is bordered by wide strip of black wool, and the middle part of crest is reddish-yellow. Body of this animal is colored bluish-gray; stomach is white. On long tail rich brush of white wool grows. Position and character of movements of tail at this animal expresses its condition at present moment.
The voice of forest trumpeter has determined its name: it sounds like lingering blares.
Jaws are long and rather weak: animal eats mainly soft food - leaves of trees and bushes. To browse it from branches on top jaw nose and upper lip have formed similarity of short proboscis, as if at tapir.
Wood trumpeters live in forests near large rivers where giant grasses and bushes plentifully expand. Hoofs of this animal are well adapted to walking on fenny ground and then forest trumpeter is able to swim well.
This mammal lives by couples kept for the whole year. The male incurs protection of territory borders marking them by heaps of manure. Also he warns the probable contender that the territory is occupied with the help of shouts. Wood trumpeters are especially “vociferous” in the morning. They actively shout while above river valleys there is dense fog: probability of predator attack is less so.
Once a year, mainly at the end of dry season female gives rise to one cub. By colouring it is similar to adult animals but on the head instead of crest only strip of black wool is. The young animal keeps with parents almost year, and female banishes it shortly before birth of the next cub. The animal becomes the adult at the age of four years.

Sulawesi trumpeter (Buccinotherium celebensis)
Order: Artiodactyls (Artiodactyla)
Family: Thunderhorns (Brontocornidae)

Habitat: Sulawesi Island, forests.
In Neocene, the fauna of Sulawesi Island represents a combination of natives of the Indomalayan realm in the west and the Australasian realm in the east, like it had taken place 25 million years ago, in human era. One of the local groups of animals of Asian origin is the new thunderhorn family of Artiodactyla order. They differ from their ancestors – feral goats or sheep who survived humans – primarily in that their hollow horns have modified into resonators with which the beast can utter loud sounds. The corneous covering on the horns of various species of thunderhorns displays various stages of reduction, up to its complete disappearance.
The Sulawesi trumpeter is a close relative of the forest trumpeter, a continental species of thunderhorns that is one of the largest in the family. But due to the limited resources of its island habitat, the Sulawesi species is smaller than the mainland one – its height at the withers does not exceed one meter, and its weight is no more than 200 kilograms. The skull of this animal is elongated, and more than half of its length is made up of a rounded and laterally compressed hollow resonator crest, with which the animal can emit droning trumpet sounds. Like other members of the family, Sulawesi trumpeters are characterized by sexual dimorphism: males are larger, their resonator crest is better developed, and most of the body is colored black or dark brown, but the belly, the edge of the resonator, and the “glasses” around the eyes are white. In females, the resonator is smaller, and they are colored brown, but white wool grows at them on the same parts of the body as in males. The vocalization of representatives of this species is a continuous deep hum.
Leaves of trees and shrubs, as well as buds, twigs and fruits, serve as food for the Sulawesi trumpeter. In order to pluck them, the upper lip and nose of the beast fused into a movable proboscis, resembling the proboscis of a tapir. The lower lip is also very mobile and helps the animal to eat food. These ungulates live in herds consisting of an adult male, several females and their young. At the end of the dry season, the female gives birth to one well-developed cub, which can move independently within an hour after birth. The young animal stays with its parents for almost a year, after which the female drives it away and gives birth to a new cub. Puberty in a young animal occurs at the age of 2 years.
Due to their good swimming abilities, thunderhorns of the Buccinotherium genus settled also other islands of Southeast Asia, where they formed closely related species. Jakarta Coast and Borneo is inhabited by the Jakarta trumpeter (Buccinotherium bataviensis), which is the least differ from the mainland species. This species is slightly smaller than the forest trumpeter, its fur is colored light brown, and on the resonator, there is a reddish border along its back edge. It mainly inhabits mountain forests, avoiding swampy lowlands. The Philippine island of Mindanao is home to a dwarf or Philippinese trumpeter (Buccinotherium cervicolor). This thunderhorn is the smallest species of trumpeter: its height at the withers is only 70 centimeters; the wool is dark brown with small white spots on the rump and sides. It inhabits tropical forests of various types and willingly settles near water. The food of this species consists mainly of terrestrial plants, and its proboscis is shorter than that of other species. Another species, the maned trumpeter (Buccinotherium jubatus), inhabits Sunda Land (Lesser Sunda Islands). Male of this trumpeter species is remarkable in even more expressed sexual dimorphism: it has a mane growing on the underside of its neck, like the New Zealand sylvammon, which looks similar to them. The maned trumpeter is ocher-red in color; the fur along the edges of the resonator horn is white; in size, this species is approximately equal to the Sulawesi species. It inhabits lowland forests and often grazes in mangroves. If necessary, animals can swim to neighboring islands.

Shadhavar (Shadhavar fabulous)
Order: Even-toed ungulates (Artiodactyla)
Family: Thunderhorns (Brontocornidae)
Habitat: Hindustan, Southwest Asia up to the Persian ridge, plains and light forests.

Picture by Leonard Popov

Initial image - picture by Pavel Volkov

In Oriental (Persian) legends shadhavar is the fantastic creature : the antelope-like one with unique hollow horn. According the legend when the wind blew, the horn of this antelope sounded attractively to other animals. When curious animals approached closer, shadhavar rushed on them and ate: the word of mouth attributed to this fantastic animal furious behavior. And only the voice of the wild pigeon could charm this animal so that hunters could catch it.
But legends have disappeared together with people, and in savannas and light forests of Southern Asia the animal somewhat resembling the legendary creature has appeared. Its behavior is not so furious, as at the fantastic prototype, but some other properties rather approach this hoofed mammals from thunderhorn family with fictious creature. The horn of this animal is especially remarkable: bases of pair horns are pulled together and have grown together to the single structure resembling the crest of dinosaur Parasaurolophus. Only this hollow horn is straight, also continuing a line of animal head. The length of horn exceeds length of other skull in one and half time. The corneous cover on this structure has disappeared completely; "horn" is covered with short thin wool. It is not more used for fight, its purpose is to be the resonator and partly to carry out alarm function. The tip of horn is covered with black wool: it is a mark for recognition of neighbours. During ritual combats males bend head down so that the horn sticks upwards as it is possible. This way they determine the strongest one without fight. The horn of the female is shorter, and the black tip on it is not so big. Due to horn the male can utter lingering trumpet shout of high tone. The voice of the female is more silent, than at the male.
By other features shadhavar resembles other artiodactyls. It is herd animal by proportions similar to fallow deer. It lives in bush thickets in foothills and valleys, in summer rising highly in mountains. It keeps in herds by 10 - 20 ones. The basic background of body colouring is yellowish - grey, on wool there are longitudinal black stripes, lasting along all body from shoulders up to hips. These stripes help animals to disappear among bushes and do not allow predators to distinguish separate animals in herd (colouring of zebras works by similar mode). The animal can jump high.
It eats mainly leaves of bushes and soft grasses.
The coupling season falls to the end of summer. At this time males establish hierarchy and gather harem from 5 - 6 females, protecting them from other males. After coupling season the hierarchy is almost erased; and recent contenders do not pay attention against each other. Once a year, in the beginning of spring the female gives rise to two calves. They have no characteristic horn, and their voices sounds like lamb bleating. Calves are covered with small spots which merge in longitudinal strips later. Approximately to the age of one year at them the horn starts to form. At the female it reaches full development to the age of three years, at the male – up to the fifth year of life. Sexual maturity comes in three years, but males really can participate in breeding from five - six years.

Desert whistlehorn (Stridocornis aridophilus)
Order: Artiodactyls (Artiodactyla)
Family: Thunderhorns (Brontocornidae)

Habitat: semi-deserts and deserts of Near East and Northern Africa.
In human epoch hoofed mammals have strongly suffered from people activity. Destruction of their habitats and active hunting had resulted to that only few of them have survived up to Neocene. Indirectly reduction of number of hoofed mammals had resulted to that other groups of animals have started to master their ecological niches. Nevertheless, evolution of “true” hoofed mammals in Neocene has proceeded, and they even had formed new groups which had not existed in human epoch. One of such groups is a family of thunderhorns. They are mainly inhabitants of open spaces and light forests of Southern Asia and Northern Africa. One of representatives of family, the desert whistlehorn, has mastered life in rather difficult conditions: it lives in droughty district bordering from south and east coasts of Mediterranean salt swamps.
This animal of graceful addition looks similar to gazelle. The desert whistlehorn is medium-sized animal: it weighs only about 60 - 70 kg, its withers height is about 1 meter. Its legs are long and thin, with rather small hoofs. The desert whistlehorn can run very quickly, accelerating on a short distance to speed over 80 kms per hour. Because of small hoofs it avoids viscous ground: sandy sites of desert and boggy saline soils. In a dry season these animals meet on clay sites of desert, but in short rain season they leave in territory with dense and drier ground.
Body of the desert whistlehorn is one-color, sandy-yellow; wool on back is lighter up to almost white. Tail is long, with hairy brush of light hair on the tip. Characteristic feature of representatives of family is resonator chambers of various shapes on the head. At the whistlehorn they look like the vertical semicircular “crest” covered with black cross strips on light background. As at all thunderhorns, this outgrowth is formed by cavities of former horns, and serves for strengthening of sounds uttered by animals. However, the outgrowth is not only the resonator: the bone forming it is very thin also is penetrated with plenty of blood vessels. This adaptation also serves for cooling, effectively radiating surplus of heat. Of course, animals with such structure on head are not able to butt, therefore relations of hierarchy in herd are established mainly with the help of loud voices, pushes by shoulders and impacts by hoofs. But at whistlehorns the special form of expression of submission has appeared: weaker animal licks crest to stronger one. The sense of this behavior is, that evaporating saliva helps the licked animal to cool. This behavior became an element of courtship ritual of animals: the male “licks” a crest of the female like this, but only stronger ritualized, slightly touching it by tongue.
The desert whistlehorn lives in hot and droughty district, and eats various plants, including bitter and even poisonous for other animals ones. It can not drink for a long time, receiving a metabolic water from the eaten plants.
This animal keeps in big herds, in which hierarchical relations are established only in pairing season. At this time males start to utter loud sounds: long and also shrilly whistle through nostrils, blowing air through an outgrowth on a head (of course, it is connected with nasal ducts). Showing the resonating outgrowth to females, the male bends head back, showing it on the background of light wool of back.
In epoch when the climate became drier, the part of population of whistlehorns dwelt in Northern Africa has passed the Mediterranean bogs by way of isthmus connecting territories of Tunis and Sicily. In territory of Southern Europe they had turned to the special species – Etrurian whistlehorn (Stridocornis etrurius). The European species differs from African one in larger sizes, dark colouring (wool on sides and back is monotonous red), and propensity to life in foothills. Etrurian whistlehorn runs not so quickly, but dexterously swarms up rocks. It has stronger constitution, and its forward legs are appreciably shorter then back ones: it is a feature of adaptation to inhabiting on mountain slopes. Head of this animal is narrower, but higher, with short and high resonating crest. Courtship cry of this animal also differs from voice of desert whistlehorn: it sounds like abrupt loud sounds.

Nanditherium (Nanditherium altissimus)
Order: Even-toed ungulates (Artiodactyla)
Family: Thunderhorns (Bronthocornidae)
Habitat: Hindustan, forests of various types.

Picture by Lambert

Initial image by Pavel Volkov

Restoration of tropical forests after disappearance of mankind promoted expansion of areas of forest species of animals and occurrence of new species adapted to life in such ecosystems. Occurrence of forests results in impoverishment of ground vegetation and in moving of organic substances accessible to consumption to the height inaccessible to many ground animals. At ground herbivorous mammals the choice is very poor in this situation: resettlement to any other habitats where habitual conditions of life are kept, or increase of size, allowing reaching tree branches. In Africa the foliage from trees is eaten by high giraffe ostriches to which ndipinotheriums similar to huge Pleistocene sloths compete. In Southern Asia they have an ecological analogue belonging to thunderhorns family – new group of artiodactyls, characteristic for tropics and subtropics of Eurasia to the south from Himalayas.
Nanditherium, the original Indian analogue of giraffe lives in woodlands of Hindustan. As against a giraffe, this animal has very massive constitution and shorter legs. The name of this animal means “Nandi beast” after Nandi, saddle buffalo of Shiva, the god of Hindu pantheon.
This is one of the largest mammals of Eurasia. Growth of adult nanditherium male at a shoulder makes three meters, and skull is about one meter long. Animal has thick two meter long neck mobile in the basis. Cervical vertebrae are light and porous; it makes them much more lightweight at preservation of durability. Bones of legs are very strong; under terminal phalanxes of fingers/toes shock-absorbers of fatty tissue develop, increasing the area of support and reducing loading on hooves. Skin on legs is dense (as at giraffe), that interferes with stagnation of blood.
Nanditheriums browse leaves and young shoots of trees at height of about 4 – 5 meters, not having competitors among other ground mammals. Jaws of this species are long and rather weak, and teeth are adapted to chewing of soft foliage. Nanditherium’s tongue is long and mobile; it operates as a hand when animal browses foliage – it twists and tightens to mouth of animal branches from which this animal tears off leaves by mobile lips.
Colouring of nanditherium is very original and includes two types of the pattern smoothly passing one to another. Head and top part of neck of animal are colored contrastly and brightly – on white background there are large black irregular-shaped spots. Shape and arrangement of these spots are individual, and animals find out each other using characteristic pattern on head. In top part of neck white color changes to brownish, and black passes to brown; spots turn to cross strips. Neck and forward part of body are striped, strips stretch on shoulders downward from the top. On back part of body strip pattern becomes poorly appreciable and body has almost smooth yellowish-brown colouring. Bottom part of legs and stomach of nanditherium are light colored, almost white. Young animal does not have white sites on body, and strips are more contrast, rather than at adults. Black-and-white colouring on head appears only after the beginning of independent life – at males earlier, than at females.
Head resonator of nanditherium represents crest of rounded shape which lasts along the whole head. Any rests of corneous cover are completely absent on it. With the help of resonator animals of this species utter infrasounds for communication at the large distance as elephants made it in Holocene epoch.
Nanditheriums live in small herds, including male, two or three females and their posterity of several years. In forest groups of these animals tread out ways which generations of animals use. Obda, large herbivorous mammal of Siberia, changes landscape in similar way. In these places forest canopy is broken and plentiful underbrush develops, giving food to smaller herbivores. Along nanditherium tracks a steady complex of animal and plant species develops.
Similarly to all large animals, nanditherium breeds very slowly. Female gives rise to one calf once in three years: pregnancy lasts till about two years, and in the rest of the time calf eats milk. After the female has stopped feeding it, young nanditherium stays in parental group for about two years, and leaves it at birth of the new calf at its mother. At this time the adult type of colouring on head starts to appear at it, and adult animals start to behave more aggressively to the grown up animal. Young animals gather in small groups and fed, moving on tracks of adult animals. Due to large size death rate among young nanditheriums is low. Sexual maturity at these animals comes at the age of seven years. Life expectancy makes till 60 years and more.

Gunturotherium (Gunturotherium grandis)
Order: Artiodactyls (Artiodactyla)
Family: Thunderhorns (Brontocornidae)

Habitat: forests of various types in Southeast Asia – Jakarta Coast, islands.
One of the characteristic groups of herbivorous mammals in South Asia is the thunderhorn family, including the descendants of bovids, whose overgrown nasal bones form a resonator for the sounds they produce. Various species of this family inhabit the Indian Subcontinent and Southeast Asia, and some species are widespread west to the Mediterranean Basin. A relative of the Indian nanditherium, gunturotherium, which belongs to a close genus (the name is derived from the Indonesian word that means “thunder”), lives in the tropical forests of Southeast Asia.
Gunturotherium is both similar and unlike nanditherium. It is also a giant ungulate species: its body length is 4.5-5 m, males are larger. Shoulder height is up to 3 meters. Unlike nanditherium, gunturotherium has a stockier build and longer hind legs, which are only slightly shorter than the forelegs; the animal’s back is less sloping, and it cannot raise its head as high as nanditherium. It also has a more elongated body, massive legs, and a shorter and thicker neck. Tail is long, with a well-developed hair tuft at the tip.
The large elongated head is equipped with a large bone resonator – the nasal passages expand into a double tube that loops back and forth over the skull, and two bone “pockets” develop on the bend lying on the occipital part of the skull, which is why the resonator is slightly bifurcated from behind. This formation is much larger in males than in females, and is used to make a roar during the mating season. In females, the resonator is located along the skull, only slightly protruding above the back of the head. The tip of the snout is elongated into a kind of proboscis, which allows the beast to pluck leaves. The jaws and chewing muscles of gunturotherium are weak; the beast feeds mainly on the soft foliage of trees and shrubs. Like the nanditherium, this beast has a long tongue.
Alveolated cervical vertebrae lighten the skeleton without loss of strength. The beast has massive leg bones, and the skin on the lower part of the legs is very durable. Like its ancestors, it is a digitigrade animal, despite its huge body size, and fatty shock absorbers, which take on part of the body weight, are developed under the phalanges of the digits. The animal’s wool is short, and a skin fold is developed on the lower part of the neck and chest to facilitate heat dissipation. The body coloration forms a striated pattern: vertical brown stripes stretch across the light beige background on the shoulders, sides and rump. The head and lower legs are also brown, but the tuft of hair on the tail is white.
Gunturotheriums inhabit forests of various types in Southeast Asia. Like nanditheriums, they live in small groups – a male, several females and their offspring. During the day, the herd moves around its territory, beating out true “roads” like a nanditherium, and preventing excessive overgrowth of the jungle by trampling and eating young trees. The network of trails in the group’s territory is used unevenly by these beasts, and some of them are almost overgrown, but from time to time the group changes routes and eats vegetation on the old trails. In fact, the animal itself provides its own food supply by clearing and maintaining a living space for the growth of soft, fast-growing vegetation – large grasses and fast-growing begonia trees.
A stable community of many animal species is developing around the herds and trails of this species. Herds of these beasts are often followed by smaller herbivores and birds, such as ayamornis. Other birds peck parasitic insect in the animal’s wool. This animal often spends hot midday hours in the water. Gunturotherium feeds on foliage and fruits of low-growing trees and tall shrubs. Gunthurotheriums of different groups communicate with each other using resonators to emit infrasound that travels over long distances. Animals are strongly attached to each other, and mothers often communicate regularly for several years with their grown-up daughters in other groups several kilometers away.
This beast has very few enemies: only large predatory mammals and zahhak monitor lizards hunt gunturotheriums. Adult animals suffer much more from parasites and blood-sucking insects and ticks.
Reproduction in this animal is very slow – the female gives birth to 1-2 calves once every 3 years. Pregnancy lasts about two years; well-developed calves have a reddish-brown coloration with light yellow spots on the sides and an underdeveloped resonator. The calf feeds on milk for about six months, but in the third month of life it begins to taste plants. At the age of 3-4, an adolescent leaves its native herd. Life expectancy reaches 70-80 years.

Mountain camelope (Leptocamelus montanophylus)
Order: Even-toed ungulates (Artiodactyla)
Family: Camels (Camelidae)
Habitat: mountain areas of Meganesia.

Picture by Rafael Silva do Nascimento, Brazil

In Australia camels never were found in wild and they could not get to this isolated continent naturally. Woods and sea passages reliably barred them the way to the “lost world” of Australia. Only due to one species of primates, Homo sapiens had become extinct at the end of Holocene they could get to this continent as domestic animals. After human disappearance their ancestors, dromedaries (Camelus dromedarius), have become wild and have given rise to several species of herbivores competing with local marsupial animals. Among camels analogues of flatland giraffes and antelopes, and also mountain goats have appeared.
The mountain camelope is strong build relative of swift-footed camelope Leptocamelus gracilis, graceful runner of Australian plains. This species differ from plain neighbour in shorter legs and neck, and also in larger narrow head. Besides mountain camelope is covered with dense wool that helps to endure cold night of Australian Alps. It is rather medium-sized species - its weathers height is up to 1,2 m, body length is about one and half meters. Back of mountain camelope is inclined forward because back legs of animal are appreciably longer than forward ones – so it is more conveniently to graze on mountain slope. Wool of animal is colored grey with brownish shade; on ridge there is longitudinal black strip which at males is much wider and longer than at females. The hump at these camels is expressed poorly - in middle of back small swelling is appreciable. On chest and basis of neck at animals of both sexes mane of long hairs develops. On head at males very long hairs grow a rich bun. To time of rut a liquid from specific gland located on nape impregnates them – hair help to strengthen smell and to keep it for a long time. At females such hairs are not present; head is covered with short wool. Legs are ended as at all representatives of the order by two hoof-like claws and special skin “pad”; the weight of body falls to end toe phalanxes. For the best cohesion with stone surface leg soles are covered with strongly cornificate skin.
Mountain camelopes live on western slopes of Australian Alps in conditions of cool and rather dry climate. These animals prefer to live in forestless districts not coming to thickets of trees occasionally growing in valleys. They eat grass at times reaching up to plants on very abrupt slopes. Due to features of legs these animals easily jump and swarm up hillsides surviving in places where marsupials of size comparable to them can not live. Teeth of mountain camelope have the special structure: incisors are strongly jutting out forward as if a nipper, and molars grow all life: it is an adaptation to grazing of food plentifully “flavoured” with sand and dust strongly erasing teeth.
These animals live in herds of 10 – 15 ones under the rule of large male leader. He constantly supports the authority in herd with the help of might demonstrations and loud roar. In herd the significant part is presented by mature females and their cubs. At mountain camelopes one cub alternate years is born as a rule. It depends on mother for a long time studying at it to move in mountains and to search for food. Usually it becomes completely independent at the third year of life leaving mother at birth at her of the next cub. The leader of herd does not support youngsters in herd as among them his probable future contenders can grow. When young animal leaves from under parent trusteeship, it has a lot from herd leader forcing young growth to submission. Because sexual maturity at young females comes only at the fourth year they do not represent interest for the main male and also are driven out. Young animals form small herds either mixed or including only young males. At this time the part of young growth perishes from various predators. Such herds of young growth live in boundary territories between areas of breeding herds and occasionally between old and young animals skirmishes happen. When young females become sexual matured, between young males fights for “harem” possession begin. Contenders rear, collide by chests, strike impacts by forward legs in sides and chest of contender and also bite strongly. Thus fighting males loudly roar and sometimes such loud demonstration of ardour serves bad service for them: having heard such roar skilled adult males hasten to these sounds and disperse self-confident young growth adding some young females to own herd. If at the herd “sharing” place two adult males face, fight between them happens severe and frequently results to mutilations or fatal outcome. Sometimes young male can live many years without “harem”, from time to time attempting to “property” of any “married” neighbour. Sometimes such bachelor literally chases herd of the contender trying to deliver from it one or several females.
Mountain camelopes are threatened, as a rule, only with local marsupial predators. If there is no opportunity to rescue in flight, herd can pass to active defense trying to strike predator by forward legs or to bite.
Life expectancy of mountain camelopes can reach 40 years.

Caballocamelus, horse camel (Caballocamelus velox)
Order: Even-toed ungulates (Artiodactyla)
Family: Camels (Camelidae)

Habitat: savannas and semideserts of Meganesia.

Until human arrival it was no large running mammal in Australia. Birds and kangaroo were their ecological analogues. The occurrence of camels (Camelus dromedarius) introduced by people had changed the course of evolution of continent inhabitants. Marsupials could not evolve to four-footed quickly running animal, replacing hoofed mammals only from the point of view of ecology. Despite of the competition to camels, they had survived and successfully evolved in Neocenic Meganesia. They avoid a competition to descendants of camels due to feeding by different kinds of forage, and also due to effective digestion of accessible, but poorly nutritious food. As a result descendants of camels had occupied only a part of ecological niches in plains of Australian part of Meganesia. Among them there are camelopes of gracile constitution, and high giraffamels having no competitors in bottom and middle levels of tree tops. But these animals live in districts where there is though any wood vegetation. In plains of Central and Western Meganesia, to the south of the zone of forests and woodlands, another descendant of camels, caballocamelus, the gregarious mammal similar to the horse, lives.
Caballocamelus is a large animal of robust constitution: its withers height is up to 160 cm, and the general length of body is about 3 m. At this animal there is a large head on rather short and strong neck. Jaws are short and have constantly growing teeth, adapted for grinding of rigid graminoids and bush branches. The muzzle is extended to short almost immovable proboscis serving for protection against dust and humidifying of inhaled air.
The hump is small; it is stretched along the back up to waist as the low wide platen. The tail is turned to “fly-brush” having hairy brush on the tip.
The wool of caballocamelus is very short and velvety. On the bottom part of neck at adult animals a lot of lengthened hair similar to beard grows. Colouring of body is yellowish brown; on shoulders and hips there is a small amount of faltering dark strips. On legs of animal there are white “stockings”. At adult animals head is darker, rather than body; at male forehead and nose bridge have coffee-brown color. At young growth the head has the same color as the body, and on legs there is lack of “stockings”.
The foot of typical camel is adapted to rather slow movement on soft ground: toes are widely separated, sheafs between them are lost, and the support falls to some distal phalanxes. At caballocamelus the structure of foot has changed according the adaptation to fast running. Toes of this animal are connected by sinews to each other along almost all length. At young animal sinews are elastic, but to the approach of maturity they ossify. Distal toe phalanxes are thick and covered with “stockings” of thick skin. The characteristic for camels subungius, at which the leg bases, is very small.
This animal lives in dry districts with firm ground, lack of wood vegetation. Caballocamelus quickly runs, accelerating momentum about 50 kms per hour. Its pace at short distances is gallop, at long one it moves by an amble (it is a characteristic pace of typical camels). This species lives in herds numbering 20 – 40 animals.
Caballocamelus eats rigid grasses and can even gnaw prickly branches of bushes. Its three-chambered stomach (inherited from the dromedary, its ancestor) helps to digest such food. Lips covered with dense skin help to feed on prickly plants. In rain season animals can not drink till many days, being content with moisture received from plants. But in dry season these animals visit reservoirs approximately once in three days. The leader of herd knows well all reservoirs in places of inhabiting of herd, and each time animals visit new reservoir for watering.
The herd includes from 1 up to 3 harems leading by dominant males. Each male owns 5 – 10 females; their posterity stays in herd up to the maturity (young males are expelled from the herd a little bit earlier, rather than females). Young females are more often quietly poured in other herds, and single males form herds. Becoming stronger, they try to bereave any adult male of authority. Males of this species are very aggressive in courtship season: they bite each other and beat by forward legs. Skin of the male is thick, especially on shoulders and in the basis of neck – it is the adaptation for intraspecific courtship tournaments. Out of breeding season males treat to each other more tolerantly, but at the watering place harems approach to water in sequence appropriate to rank of the male in herd.
Pregnancy lasts about 10 months; one cub is born always. The female cares of it for a long time, therefore the posterity at the female is born only once in 2 years. The female does not admit neighbours to the newborn cub while it will rise on legs, and some more hours after it. At this time the cub remembers smell and voice of mother. It is very much adhered to mother, and does not depart far from her for a long time. A parental instinct at this species is very strong: in case of need all adult animals of a clan protect the cub; therefore the survival rate of posterity at this species is rather high.

Desert springhare (Macropedetes aridophilus)
Order: Rodents (Rodentia)
Family: Springhares (Pedetidae)

Habitat: arid savannas, Kalahari and the edges of the Namib desert.
The springhare (Pedetes capensis) is one of the rare examples where conservation measures in the human era helped the species recover. The ability to live in arid areas and in human-altered landscapes helped it survive the Holocene-Neocene ecological crisis and the Ice Age. At this time, it even settled in North Africa, taking advantage of the expansion of the arid savannah areas and the retreat of the jungle. Later, a distinct genus of large springhares evolved on the territory of Africa and Zinj Land, occupying the ecological niche of medium-sized running herbivores. But while the savanna kangoohopper is widespread due to its high competitiveness, its desert relative avoids competition, living in the harshest conditions of the deserts of southern Africa, where the number of ungulates is insignificant.
In its general appearance, the desert springhare resembles its cousin from the savannah, differing in smaller size. Body length is 55.2 cm; tail length is up to 60 cm. Weight is about 10 kg. The wool coloration is grayish yellow with small dark speckles on the back. Long ears and a hairless throat, which skin is densely permeated with blood vessels, serve to dissipate excess heat. This sociable animal keeps in small groups of 7-8 pairs of adult animals and immature young. Desert springhares are constantly wandering, staying only at water sources in times of drought. They feed on any kind of plants, preferring, however, sappy or starchy ones. Animals willingly dig up thick roots and tubers with their front paws, and in the midst of a drought they can eat an insect, rodent or lizard, although normally they are vegetarians. They sweat very little and get a significant part of the necessary water from food through the metabolic pathway. When the rainy season begins, desert springhares eat fill, stocking fat in their tails and on their backs. This helps many of them to survive the dry season. Only during the rains they feed in the daytime, and in droughts they prefer to graze and move at night, searching for temporary shelters in the morning – each time in a new place.
The mating season for these animals begins at the end of the dry season. At this time, males are fighting for females, making high jumps and chasing each other. In extreme cases, the fight ends with “boxing” with the front paws, like in kangaroos. Despite their powerful incisors, males do not bite each other, although they often defend themselves from predators with bites. Pregnancy lasts for 2 months; the cubs (1-2) are born during the rains and are quite developed. At the age of 10 days, they already follow their mother, not lagging behind. At the age of 3 months, they are already independent, and by the beginning of the new mating season they leave their parents, joining relatives from other groups. At this time, they are already ready to mate, and fights between young males in such groups are especially fierce – they are ambitious and inexperienced. But a significant part of the young die from stress and predators during the search for other groups of congeners. A solitary animal is constantly agitated, behaves very nervously and is often frightened by random sounds. Life expectancy is 10-12 years.

Siberian digger (Paramarmota architector)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: Western Siberia, flat districts, river valleys.
Small animals had gone through mass extinction of the epoch at the boundary of Holocene and Neocene much more successful, rather than large species. Their variety at the level of families remained practically the same, as before the catastrophe; separate genera had died out, but new ones appeared to replace them. Ecological niches occupied by them had remained the same – these are small forest and grassland animals, herbivores and omnivores. Among them also digging forms remain, for example, suslic doggies from three-Rivers-Land steppes. In severe continental climate of Siberia the separate species of digging animals settling in large colonies, Siberian digger, also have appeared. The colonial habit of life provides more successful survival of these animals in conditions of contrast continental climate and severe long winter. This animal descends from one species of suslics inhabited glacial steppes during the congelation at the boundary of Holocene and Neocene.
From the point of view of anatomy Siberian digger represents very large suslic – one average animal weighs up to 3 kg. Ecological analogue of Siberian digger is the marmot – digging animal building extensive underground constructions. The colony of Siberian diggers numbers up to 200 – 300 animals, and they construct under the ground a huge settlement which part is placed at the depth up to 4 – 5 meters, inaccessible for predators.
Settlement of these rodents represents the circuit of underground tunnels supplied with drainage “shafts” and drainage burrows which open in steep riverbank and can stretch to tens meters from edge of colony. It is necessary for protection of colony in spring from thawed snow. Besides exits to the surface are made as high (up to two meters) earthen hills with an entrance at the top. At snow thawing in them only a little of ice-cold water will get. From these hills the good view opens, therefore in summer at tops of hills “sentries” – males from among defenders of a colony –are constantly on duty.
Except for earthen hills – entrances to the colony, presence of colony is marked by the bushes and young trees damaged by rodents. Siberian diggers influence a landscape as essentially, as large herbivores like obda or shurga: within the limits of their colonies trees survive hardly (they are simply chewed at the sprout stage). But above colonies of diggers graminoids and other plants, bearing drier ground (presence of drainage system in colonies has an effect) and constant “shear” of them by these rodents, prosper. Forager individuals from colony also make sorties for the forage in thickets of bushes and forest.
Siberian diggers are animals having well expressed caste system and obvious intraspecific polymorphism. Like Neocenic castle rabbits from New Zealand or naked mole rats (Heterocephalus glaber) from Africa of Holocene epoch, these animals are divided to castes. The caste system is not fixed genetically, and depends on age and position of animal in hierarchy of colony. At these rodents there is large head with very short ears, able to wrap when the animal moves in hole. The trunk of Siberian digger is covered with rich velvety fur similar a little to mole fur: hairs grow vertically, and do not prevent movement in hole forward or back. The fur of animal is colored brown with small amount of white spots on back and shoulders. On head of adult males there is an area of white fur on sides of head and around of eyes. Depending on position of animal in hierarchy colouring of fur may vary strongly.
Paws of Siberian digger are short, with wide feet, having edge of rigid hairs –it is convenient to rake away the ground by such paws during the digging. Tail is short, with white tip. Tail lifted upwards is an alarm signal, well appreciable even from among grass.
The caste system of Siberian diggers includes some categories of animals:
1) “King” and “queen” – breeding pair of large fertile animals. But the amount of these animals is not limited, as at insects. In large colony occurrence of several “queens”, which are fertilized by one or two “kings”, is possible. If two “kings” meet in tunnels of colony, between them severe combat is possible, but usually “king” does not leave from the centre of colony. From these animals all posterity of colony descends.
“Queen” represents the individual which almost continuously gives rise or brings up young growth. It lives in special chamber; it and its posterity are looked after by some females from the number of “nurses”. “Queen” is very large – it is approximately twice larger than the adult forager female. At it milk glands are strongly advanced, and it almost continuously produces milk (except for second half of pregnancy). Because of it “queen” requires a plenty of juicy forages, and “nurses” additionally give it to drink, dragging water from drainage “shafts” or from the nearest reservoir in cheek pouches. Fertility of “queen” is about 15 naked, blind and helpless cubs in one litter. In some days after cub birth it is ready to become pregnant again. For one year “queen” makes up to five litters. “Queen” can not look after itself and posterity independently; it is only able to creep hardly in the chamber. If in spring thawed snow fills in chambers where “queens” live, they perish, being not able to escape.
“King” is the large fertile male with normal proportions of body, able to serve itself independently. It freely moves in colony, independently eats in “pantries” and searches for “queens” ready to fertilisation. At this male sexual attributes in colouring of wool are obviously expressed: on head around of eyes and on cheeks areas of white wool develop. Also “king” has repugnatorial glands: it has a specific smell which influences other males and suppresses sexual behaviour at them.
2) “Soldiers” – aggressive adult males. They are in condition of constant stress because of presence of “king” in colony. The stress causes in them formation of plenty of adrenaline, and hormonal changes lead to irreversible changes in their appearance. Incisors and jaws of “soldiers” become large; therefore the head of such individuals looks disproportionately big relatively to the body. Sexual function at them is suppressed from the childhood, especially if they developed in conditions of density in the centre of colony. These animals can hardly eat independently because of hypertrophied jaws; more often young individuals from “nurses” caste feed and clean them. But at an attack on colony they leave on surface the first, and furiously attack any animal had disturbed them, even such large one, as obda or shurga. At the edges of colony where the stress is less, features of “soldier” at males are less expressed, and among them fertile individuals, from whom new “kings” may grow, frequently meet.
Colouring of “soldier” is actually warning: at them there is almost completely white head with dark marks on forehead and nape, and white spots on shoulders are very big. Such colouring is well remembered by animals which had undergone to attack of “soldiers” of colony, and forces them to keep farther from these animals.
3) “Foragers” and “nurses” – females of various ages. Adult and old females are foragers. They constantly gather forages and drag them in holes serving as “pantries”. These animals are able to feed and look after themselves independently. Young females have function of “nurses” – they look after “queens” and “soldiers”, clean and feed them. At them the parent instinct is early expressed, but it equally quickly fades. If in the short period of maturing the female was not fertilized, it becomes the forager. Young “nurses” have opportunity to become “queens”, if they will be fertilized within first three months of life. At pregnancy there is a hormonal reorganization of the organism, and young female develops to “queen” occupied with reproduction.
If the colony becomes too large, in it “diarchy” can arise: at the edge of colony the young male (from among the individuals less subject to stress) and the female ready to breeding from the number of “nurses” can create new breeding family. If founders of colony perish, their place is occupied quickly by individuals from among young ones. Frequently young males from other colonies come in colony. They lodge at edges, and also can become founders of new “dynasty”.
Siberian diggers eat exclusively vegetative food. Everything, that can be stored within winter, is reserved in special chambers serving as “pantries”. These are tubers and rhizomes of plants, and also seeds of graminoids. Daily food of animals in summer includes young branches of bushes, greenery and roots; the autumn adds to them fruits of various plants. Foragers of this species carry food in cheek pouches. In them there are no salivary glands, therefore the transporting forage stays dry and does not spoil in winter.
In winter activity of colony is reduced: animals spend the most part of day in dream. When bad frosts come, all colony runs to true hibernation, at which the body temperature of animals is strongly reduced, and vital processes are inhibited. At this time even development of embryos at breeding females stops. Due to this feature consumption of forages does not increase, and the colony successfully exists up to the end of spring when there is an opportunity to pass to fresh forage. When snow thaws, flooding of the part of colony is possible, but the majority of animals usually survives. When all difficulties are left behind, and in nature there is enough of fresh vitamin forage, in colony the burst of birth rate takes place. The care of posterity raises survival rate of young growth, and damage, caused to the colony by predators and weather, is restored.
Life expectancy of foragers and “soldiers” seldom exceeds three years, but “kings” and “queens” can live till ten years and more.

Ratatoskr, transpolar squirrel (Sciurus fennicus)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: krummholz of Khibiny Mountains, Karelia, east of Scandinavia.

Picture by Pavel Volkov

Squirrels form a very numerous and successful group of rodents. By the Neocene, they had successfully survived two glaciation epochs and the human epoch between them, losing only a number of local and tropical species. However, in Neocene, they had gone through an outbreak of adaptive radiation, giving rise to a whole range of new species, including quite large ones. But in Europe, there are also small species that continue leading the typical lifestyle characteristic for this group in the human era. One of these species is ratatoskr, or transpolar squirrel, a descendant of the European red squirrel (Sciurus vulgaris); it is named after a squirrel from Scandinavian mythology (literally “gnawing tooth” or “climbing tooth”).
The length of the animal’s body is up to 25 cm, the tail is 15 cm long, and the weight is about 350 grams. The wool color is gray; the head has a red “mask”, and there are characteristic hair tufts on ears. In winter fur, the coloration becomes light gray, almost white, with a buff “mask”. In general, ratatoskr is an animal of fairly typical appearance, not much different from its ancestor outwardly. But these rodents live in groups of 6-8 individuals: a breeding pair of parents and their brood. Ratatoskrs are quite sociable animals: while searching for food they constantly whistle to each other, and in case of alarm they utter a chatter. Quite often it is possible to see them jumping along the trunks and branches of trees. This is usually a kind of display of the unity of the group members. Ratatoskr feeds on any plant food – conifer needles and seeds, leaves, buds, nuts, birch catkins and mushrooms. Also, a significant part of the diet consists of small animals – invertebrates, chicks and small rodents. In winter, these squirrels can even hunt rodents by sneaking into their tunnels in the snow. A group of squirrels stores nuts and mushrooms for the winter, hiding them in hollows, holes, or burying them in moss and earth. The squirrel nest is built in the fork of the branches not far from the trunk, and in krummholz, usually near the upward bend of the tree trunk. Its entrance is located in such a way that it is difficult for these animals themselves to get through there: this is a protection from predators. However, ratatoskrs can mob predators with staccato sounds and chatter, especially if they are confident in their safety. This vocalization is caught by birds then, and it disrupts the predator’s hunt.
The breeding season is in April–May, and in the fruitful years there may be another one in July. Males follow the female, aggressively defending her from competitors – they purr loudly, knock on branches with their paws, and run after each other. After mating with the winner, the female builds or repairs her nest. Pregnancy lasts 36 days; there are 4-6 cubs in the litter, and in the second litter there are only 2-3, but larger ones. Newborn baby squirrels are naked and blind. They feed on milk for 6 weeks, gradually switching to an adult diet, after which they leave the nest and roam the territory with their parents. Usually, young animals leave the group in the spring of the following year, shortly before the beginning of the next breeding season. They reach sexual maturity at 8 months of age, and reproduce the following year. Life expectancy is up to 8 years, but many individuals do not live to 5 years, because ratatoskr has many natural enemies – small predatory mammals and birds.
To the south, in Central and Eastern Europe as far as the Urals, the related species lives – the rusty ratatoskr (Sciurus fuscops) with red wool and a brown “mask” that does not change color in the winter fur. Unlike the larger cutter squirrels and its northern relative, the rusty ratatoskr is a solitary one. It resembles its ancestor in its lifestyle, outwardly differing only in the presence of “mask” on its head and more abrupt and fussy movements.

Stripe-tailed squirrel (Callurosciurus fasciatus)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: Honshu Island (Japan Archipelago), tropical rainforest.

Picture by Alexander Smyslov

It is difficult to name squirrels as “living fossils”, because this group of rodents is widely settled on the Earth and inhabits various biomes – from deserts up to tropical forests. However, long before human appearing squirrels were already quite recognizeable animals and their very successful body plan was kept from Oligocene. The majority of squirrel species, except for inhabitants of tropical forests and not numerous local species, has successfully gone through human epoch, and in Neocene their species are as numerous and various, as in pre-human epoch of Cenozoic.
In Japan Islands numerous species belonging to endemic for these islands genus Callurosciurus live. Their typical representative is stripe-tailed squirrel, the owner of spectacular tail. The area of this species includes tropical rainforests at the east of Honshu Island. This species has all typical features of genus. The body length of stripe-tailed squirrel is rather small – no more than 15 cm. But tail of this creature is very remarkable: its length is more than 20 cm; it is cross-striped, black-and-white, as at common lemur (Lemur catta) of human epoch. Tail of stripe-tailed squirrel is rather thin, but covered with rich wool and looks as cylindrical-shaped one. It is used as the balance weight at climbing and jumps, but its basic function is a little bit other – with the help of tail this squirrel declares to the congeners that the territory is occupied, and also gives other signals. Similarly to all representatives of genus, stripe-tailed squirrels are very territorial animals. Each individual chooses a site in forest canopy, carefully marks its borders with nibbled areas of bark and odorous marks, and jealously protects the occupied territory against intrusion of congeners.
Body of stripe-tailed squirrel is colored not as distinctly, as tail is. The basic background of body colouring is grey with small brown specks. On head there is a white “mask” covering forehead, top and lateral parts of head. Colouring of ears sharply contrasts with this background: ears are black and edged with red hair. Such colouring is well appreciable among foliage, and squirrel could become easy prey for predators. However these animals have effective system of the notification of congeners. In spite of the fact that stripe-tailed squirrel does not endure the presence of congeners in the territory, it constantly exchanges sound signals with them. Having noticed a predator, squirrel utters alarm signal – shrill thin peeping. It is well known to all inhabitants of tree crones, and stripe-tailed squirrels are among the main informants about presence of predators in forests of Japan Islands. Having heard alarm signal of the congener, each individual repeats it necessarily. Duration of repeated signal depends on loudness of heard sound, therefore it is possible to define approximately where there is a predator noticed by them, listening voices of squirrels.
Stripe-tailed squirrels arrange dreys on trees. They have completely passed from life in hollows, and only build their own dreys. These rodents belong to number of the most skilful builders among mammals. They plait spherical dreys, remotely similar to nests of weaverbirds, on tips of long shaken branches. Building its drey, squirrel bends branch in a ring and connects it with vegetative fibres, or plaits to each other the lateral branches growing on it. This ring becomes a basis of nest. New branches forming a skeleton of nest are added to it, and space between them is braided with fibrous stalks of fern fronds or leaves of epiphytic plants. From inside the drey is covered with leaves. The drey entrance is located below, but the narrow corridor stretches along lateral wall and opens in the top part of nest.
Stripe-tailed squirrels do not form constant breeding pairs. Pairing tales place at any time of year, but most intensively two times per year: in spring and in the middle of summer. Males leave their territories and search for females ready to breeding. Females constantly mark borders of territories with urine, and its smell helps the male to determine, whether it is possible to be coupled to this or that female. Male courtship actions have formal character – it pursues the female and tries to catch her tail. If to it succeeds to do it (accepting male courtship, female allows it to make it), fast pairing follows, after which female banishes male. Nevertheless, male keeps for some time on border of her territory, driving away any contenders. When female loses interest to male courthship, its urine gets other smell and male, feeling it, leaves borders of her territory.
Having built a drey, female uses it for some years, constantly renewing and repairing, but then abandons it. In litter it may usually be up to 5 – 6 cubs. They grow quickly, and at the age of 2 months already become completely independent. As against adult individuals, at young animals the tail has no black-and-white strips – it is almost completely grey with light tip. Also head has no white “mask” which appears only closer to the time of sexual maturity (at the age of 4 – 5 months).
Life expectancy of this species in nature can reach 4 – 5 years, but the majority of animals does not live up to the third year of life.

Flame-tailed squirrel (Callurosciurus flammeocauda) is the most spectacular representative of genus. Its native land is the area of tropical forests of Shikoku Island. Body of this squirrel is black on back and sides; top of head, nose and sides of head are white, stomach is rusty-red. Tail looks very impressively: it is deep red; tip is yellow passing to white. Declaring rights to its territory, flame-tailed squirrel raises tail and trembles it. Thus it utters shrill high-frequency squeak; and some birds and predatory mammals can not endure it. This species of squirrels arranges drey, braiding two branches of near growing trees. In the beginning of drey construction squirrel should show miracles of acrobatic skills. Hanging on the branch, squirrel shakes it and tries to grasp a branch of near growing tree. When it succeeds to do it, squirrel gnaws out from one branch narrow strip of fibres and ties both branches together with it. After it I done, squirrel starts building of typical spherical drey between them.

Long-tailed squirrel (Callurosciurus longicauda) is one of large species of this genus, widespread in tropical and warm to temperate forests of eastern side of Honshu Island. The length of its body is about 20 cm, and very long striped tail reaches half-meter length. Body of this squirrel is grey and has glaucescent shade; along both sides wide black strips stretch. There is the same strip on each side of head – it stretches from tip of nose through eye up to the basis of ear. On neck and shoulders strip is fuzzy, turning to dark grey spot, and appears again on sides. Tail of this species is white with red tip.

Reed squirrel (Callurosciurus calamophila) lives in swampy forests at the east of Honshu Island and prefers to keep in thickets of reed instead of trees. It is a tiny species: body length of adult individual does not exceed 10 cm; tail is of the same length. Body of this squirrel has grey colouring with several longitudinal strips of rusty red color on nape, neck and back. Ears and nose bridge, and also hands and feet are colored black. Tail sharply contrasts with body in colouring: it is snow-white with bright red tip. Declaring the rights to territory, this squirrel hangs upside down on reed stalk, uttering thin squeak and having raised tail up. Drey of this squirrel represents a kind of ball of reed plaited very densely and littered with vegetative fibres.
In mountain forests of Honshu Island golden-tailed squirrel (Callurosciurus chrysocaudata) lives; it is the largest and hardy species. The length of body of this species reaches 40 cm; tail is about 50 cm long. The adult animal of this species weighs about 1,5 kg. This is an animal of heavier constitution, than heat-loving species inhabiting tropical forests: it has rather large head and shorter ears and paws. Golden-tailed squirrel lives in coniferous and deciduous forests in mountains of island where snow in winter lays, and eats seeds, buds and young shoots of wood plants. In summer it willingly eats mushrooms growing on trunks of old trees. Wool on body of this species is colored grey with glaucescent shade, darker on back. Tail is straw-coloured with black tip. Also ears of animal and “eyebrows” above eyes are colored black. Voice of this animal is similar to bark of small dog, and warns other animals of presence of predatory birds and mammals.

Cutter squirrel (Gravisciurus forfex)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: mixed forests of Central and Southern Europe.
Genus of true squirrels (Sciurus) had proved the viability and evolutionary success. Having evolved in Oligocene, these rodents have successfully gone through epoch of anthropogenous pressure – only some local endemic species and species sensitive to anthropogenous influence had died out. The majority of squirrel species had kept sufficient number and after disappearance of mankind in forests their various descendants had appeared.
The descendant of common squirrel (Sciurus vulgaris) widespread in whole Eurasia in human epoch lives in European forests; it is very large cutter squirrel. It has kept a significant amount of attributes of ancestral species, differing greatly only in size and heavier constitution. Its color of wool is the same as at ancestor, but on red background on hips darker spots are scattered, and white tip of tail is shaded with a belt of brown color. Also this animal has dark ears.
Paws of cutter squirrel are rather shorter and thicker, rather than at squirrels of human epoch. But tail of this rodent is longer, than at an ancestor, and is covered with long fluffy wool.
Cutter squirrel is one of the largest species of forest animals of non-tropical part of Eurasia. The length of its body is about 50 cm, and weight reaches 3 kgs. The increase of body size is connected to features of its diet. This species of squirrels eats vegetative food only: since spring up to late autumn basically leaves and thin branches, and conifer needles in winter. After feeding of these rodents the tree looks clipped awkwardly – if the family of cutter squirrels stays on it for a long time, they eat a significant part of young shoots which they can reach. The inhabited tree, however, is never eaten round, and dung is dumped on the ground from near growing trees frequently growing in tens meters from the location of drey. Bacteria helping rodents to acquire nutrients from rough forage live in a stomach and intestines of these squirrels. Due to large caecum these squirrels can digest conifer needles. Oils and resinous substances are not acquired by them; therefore in winter dung of cutter squirrel has characteristic resinous smell.
Cutter squirrel lives in small groups: male, female and 1 or 2 recent litters. The group occupies territory of about 15 square kilometers. Here on strongest trees some dreys changing by pair of parent animals before birth of the next litter are located.
Drey of these squirrels represents massive construction of bound rods and split branches. Incisors of these rodents are strong enough to bite off branches up to one centimeter thick and to split them lengthways. The drey entrance is placed near the trunk; therefore it is difficult to get there even for these animals. But it gives additional protection against predators, because it is difficult for them to make the way in drey of these rodents. Inside the drey there are some inhabited chambers littered with soft foliage and grass.
Because of their large size cutter squirrels climb not as dexterously, as their ancestors. In manner of movement they resemble more monkeys or lemurs: they run on four paws along horizontal branches and make rare jumps. When animals move, tails are raised vertically and contrastly painted tip is visible. During the feeding these squirrels sit on hinder legs and tail hangs downwards.
The courtship season at this species is very long, but animals show the greatest activity since January till May. Pregnancy lasts till about 35 days, in litter there are 3 – 4 cubs. In northern parts of area usually there is only one litter per one year, in southern parts there are two ones. Mother feeds the posterity with milk till approximately one and half month, and till about one month young animals keep with parents. They reach sexual maturity at one and a half years. Life expectancy makes till 20 years.

Great urma (Urma magna)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: northern Europe, coniferous forests.

Picture by Pavel Volkov

Initial image by Alexey Tatarinov

Rodents are the dominant group among Neocene mammals. After the end of Holocene epoch, they quickly regained the abundance and diversity characteristic of the human epoch. In the process of evolution, forms have appeared among them that have mastered new ecological niches and food sources. One of these rodents is great urma, a large member of the squirrel family that inhabits the coniferous forests of northern Europe. The name of this animal comes from the ancient name of a squirrel in the north of Russia.
Great urma has retained the recognizable appearance of its ancestor: in fact, it is just a very large squirrel. The weight of an adult reaches 8 kg; the body length is up to 50 cm, not counting the tail. The fluffy tail is about 1 meter long. It is a slow-moving arboreal animal, similar in movement to some prosimians – great urma very rarely makes long jumps, preferring to walk along the branches. While moving, it does not cling to the bark with its claws, but wraps its digits around the branches. The fingers of the forelimb are divided into two groups: II + III can partially oppose to IV + V. This allows the beast to grab the branches and hold on to them tightly. The hind legs are also tenacious; the thumb is opposed to the rest. The background coloration of the summer coat of great urma is brown, the wool on the chest and lower jaw is white, but it is black on the forehead and back of the head. The last third of the tail is also white. The winter wool color is changed from brown to ash-gray, but the white and black markings remain.
The large size and slowness of great urma are related to the peculiarities of its diet: this animal is a kind of analogue of the koala in the northern forests, since it feeds on affordable and difficult-to-digest food – pine needles and young shoots. This animal has a wide cheekbony muzzle, large jaw muscles and strong jaws, so the animal easily bites off needles and young shoots, and chews them with molars equipped with folded enamel, which continue to grow throughout all its life, like incisors, but in slower rate. Urma’s stomach is relatively large and two-chambered – portions of food are primary processed in it. The animal has a long intestine with a well-developed cecum. Urma spends a lot of time sitting on thick branches, hanging its tail down and digesting food. Coprophagia is characteristic for this species – feces from the cecum are recycled and maximum nutrients are extracted from it. The final droppings of great urma are dry, with a strong resinous odor. Due to the specific diet, animal meat also has a pronounced resinous scent.
Additional food sources for urma are bird eggs, chicks and small rodents, as well as insect larvae living in rotten wood. Animals often descend to the ground in search of invertebrates. On the ground, animals keep their tails up, but with the tip down. In case of danger, the animals lift their tails up and emit a high-pitched call, similar to crying. In the event of a predator attack, great urma does not flee, but goes on active defense, inflicting deep lacerations with its incisors. White and black spots on the animal’s face represent an aposematic coloration. Usually, great urma keeps in families of two adults and their offspring, and the defense of an entire family can put even a large predator to flight. The breeding pair persists for several years in this species.
The nest of this species is a large spherical structure that is constructed in the upper part of a large tree with a broken top. The diameter of the nest can reach two meters. A couple of animals uses the nest for several years, regularly changing the litter and renewing it by the time the offspring are born. Once a year, in late spring, the female gives birth to 3-4 blind and helpless cubs covered with velvety red fur. As they grow, the fur turns brown, and by autumn, young animals have patches of white and black fur, that are characteristic for adults. The young animals spend the first winter with their parents and leave them in early spring, when the male begins to express aggression towards them. Puberty occurs in the second year of life, and life expectancy is about 10 years.
Beyond the Urals, great urma is replaced by a similar species – the giant urma (Urma gigas), adapted to life in a continental climate with harsh snowy winters. It is a large ground-dwelling squirrel (the weight of an adult is about 12 kg), which lives on the northern border of the coniferous forest zone and in the mountain ranges of Siberia, preferring pine forests. Obviously, vast tracts of larch forests are becoming an obstacle to the settlement of this hardy species to the west, to Beringia and North America, as they deprive it of the necessary winter food. This species feeds on pine needles and builds large dome-like nests on the ground. Giant urma has thick white winter fur without black spots. The summer fur is grey with white spots on the chest and black cheeks. These animals also actively defend themselves from predators, uttering a high-pitched squeal and holding their short fluffy tails vertically. In the litter of this species, there are 2-3 large cubs, which grow quickly and spend their first winter in the parent nest.

The idea of the existence of this mammal species was proposed by Tim Morris, Adelaide, Australia.

Beringean mountain squirrel (Tamiasciurus beringea)
Order: Rodents (Rodentia)
Family: Squirrels (Scuiridae)

Habitat: mountain forests of Beringia, northwest of North America.

Picture by Alexander Smyslov

Similarly to many other rodents, various squirrels, including North American red squirrel (Tamiasciurus hudsonicus) have rather safely gone through the period of anthropogenous pressure at the end of Holocene. Climatic changes which had shifted southern border of coniferous forests zone farther to the south appeared very favourable for this species.
But the ice age is a temporary phenomenon, and after thawing of glacier various deciduous trees had started to spread to the north, having pushed coniferous forests of North America closer to polar areas, and also to the west, to Beringia. The part of the population of American red squirrel had receded to these forests where had evolved to new species – to Beringean mountain squirrel.
Beringean mountain squirrel is rather large rodent – males weigh 350 – 400 grams, females up to 300 – 350 g. It grows up to 25 – 30 centimeters long with fluffy tail of the same length. On body fur is also longer and fluffier, rather than at ancestor, even in summer because of colder climate in their inhabitancy – northern and mountain (even high-mountainous) coniferous forests.
As against the ancestor, Beringean mountain squirrel is not red, and most likely bluish-gray, like a color of stones and dark needles of trees in its inhabitancy; also it has kept lighter belly, characteristic for its ancestor, and white rings around of eyes have increased to large light spots on cheeks. On ears of these squirrels short signal brushes of darker color grow, and at sexually mature males also there is a dark strip along back; occasionally there are melanistic individuals.
Beringean mountain squirrel is easily adapting animal with diverse diet. It eats seeds of many species of coniferous trees, also some berries, mushrooms, various insects and spiders, and ravages nests of small birds. This species equally freely feels like both on trees, and on the ground therefore it has superseded from northwest of North America various chipmunks conceding to Beringean mountain squirrel in force and quickness.
This squirrel lives on trees where it builds a typical squirrel drey of branches of conifers, or occupies empty bird nest, reconstructing it as it needs. From within this drey is warmed by female’s underfur, and in spring female gives birth up to 5 – 6 blind and helpless cubs; she brings them up alone and looks after them within 2 months. Elder cubs remain with mother, but study to search for food and to escape from enemies. At the age of 5 months squirrel cubs become independent and leave her, and to one-year-old age they become sexually mature. While female looks after posterity, male stays in her territory, gathering food and feeding up the female. When cubs leave drey, male joins family. When the posterity leaves the female, male also goes away from female’s territory.
Beringean mountain squirrel is sociable enough animal. Breeding pairs living in neighbourhood relate to each other loyally enough, but in courtship period between solitary males rather severe fights break out, accompanied by very painful bites and long pursuits in tree crones.
If Beringian mountain squirrel will be eaten by nobody (and it is a prey of various small and medium-sized predatory mammals and birds of coniferous forests in mountains of Beringia), it can live up to 7 – 8 years.
To the east from Beringia, in northern forests of North America the species related to Beringean mountain squirrel lives – taiga squirrel (Tamiasciurus borealis). It differs from the mountain relative in more habitual red color of wool, but in the rest it is practically similar to previous species. Only white marks on its head are larger, and wool on stomach is snow-white.

Florida giant squirrel (Tardisciurus palmophilus)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: southeastern part of North America, tropical and subtropical forests of the Atlantic coast.

Picture by Alexander Smyslov

The eastern grey squirrel (Sciurus carolinensis) is one of the most successful mammalian species of the human era. Due to the ability to live next to humans, this mammal has significantly expanded its range and increased its numbers. After the human extinction, this species partially lost ground, but some populations adapted to life in newly emerging ecosystems and turned into new species. In the tropical and subtropical forests of southern North America, one of the descendants of this species is Florida giant squirrel, a large rodent species that has adapted to feeding on large seeds of plants with a hard shell.
Among all the variety of squirrels, this species belongs to the number of large species, although it is inferior in size to some species from Eurasia. An adult Florida giant squirrel weighs up to 3 kg; it is the size of a human-era domestic cat, but its long tail makes it appear much larger. This rodent climbs trees more slowly than its smaller relatives, although it can make jumps up to 5 meters long from one tree to another if necessary.
This rodent has a chestnut-brown wool with three darker longitudinal stripes on its back. The belly, chest and throat are of sandy yellow color. Tail is dark brown with a yellowish tip. The paws are short, with tenacious pointed claws. This species has a large head with strong jaws adapted for cracking seeds with a strong shell.
Florida giant squirrel feeds on palm seeds, nuts and acorns. Like other squirrel species, it often sets up seed depots in the ground, which it can forget about. And the seeds bitten by this rodent germinate faster, which makes this squirrel species an important link in the reproduction of a number of tree species. In addition to seeds, this squirrel readily eats soft fruits and young leaves, and also ravages bird nests, catches lizards and frogs. It often uses the remains of prey from predators, cracking large bones and licking the bone marrow out of them.
This species raises offspring in tree-trunk hollows, but in their absence it makes a wicker nest on the top of palm tree. The female weaves its nest into the fibrous leaves of a palm tree and strengthens it with twigs and fibers gnawed from the palm trunk. The nest is lined with moss and shoots of herbaceous plants. There are 1-2 relatively large cubs in the brood; the female brings offspring twice a year. Young animals spend about a month in the nest, and then return to it only for the night. Puberty comes at the age of 9-10 months, and life expectancy is up to 7 years.

Ursine ground squirrel (Gravispermophilus ursinus)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: California Island; shrubs, grass thickets.

Picture by Wovoka

Rodents are a successful group of mammals. Due to the flexibility of behavior and the speed of reproduction, they quickly restored in Neocene their former diversity that had been undermined by humans. They are usually represented in ecosystems by small species, but in some places of the Earth even large forms have appeared among them. At the islands, in isolation, some rodents have evolved into large forms, although their mainland relatives are small species. One of them is ursine ground squirrel, a descendant of the California ground squirrel (Otospermophilus beecheyi).
Compared to its ancestor, this species has greatly increased in size, turning into a massive slow-moving beast: body length up to 60 cm, tail about 25 cm, and weight about 10 kg. The wool color is unicoloured – brown, slightly lighter on the belly. This is contrasted by a fluffy black tail with a white tip, which serves to provide visual signals to relatives. The enamel of the incisors is yellow. The head is large, with short ears, and small eyes are shifted to the top of the head, like in its ancestor. The jaws are relatively short, and the jaw muscles are strong. This animal, large and outwardly massive, resembles a small bear when sitting on its hind legs.
It feeds on tough grasses and seeds, and if possible, it eats caterpillars, snails, bird eggs, and even carrion, although it does not search for such food intentionally. The diet also includes fruits and pulp of cacti. The animal’s behavior is relatively simple, and its brain is only slightly larger than that of mainland species of typical ground squirrel size. Ursine ground squirrel lives in long-term colonies of 10-15 pairs of animals. The permanent burrows in which the female raises her cubs represent a complex system of tunnels; they are connected to the surface by several exits. A number of living chambers and dead ends extend from the main entrance of the burrow. There are many temporary burrows in the vicinity of the colony where animals can hide from predators. The alarm signal is a whistle, and the usual sounds serving for communication sound like squeaking and rumbling. The main enemies of this species are caracarptors – the local birds of prey, which attack these rodents, catching them far from their burrows.
Twice a year, in summer and winter, ursine ground squirrel bears offspring. At this time, the family males have to drive off competitors. The battle of males for a female consists of furious screeching, jumping and tail wagging. Male often chases its rivals, holding its tail up and shaking it slightly. Pregnancy lasts 35 days; usually there are 2-3 cubs in the litter. Low fertility is a result of limited resources of the island. The cubs are born blind and naked; they open eyes at the age of 2 weeks. Lactation lasts 40 days, although at the age of one month the cubs already begin to taste the grass. Young animals leave their parent colony at the age of 5 months and reach sexual maturity the following year. Life expectancy is up to 14-16 years.

Tiny flying squirrel (Belomys minor)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: East and Southeast Asia, evergreen deciduous forests.

Picture by Lambert

Neocene is a time of new, unusual and exotic species. Freed from anthropogenic pressure, the inhabitants of the Earth continued to evolve and sometimes developed new, sometimes rather strange features. But some of them have remained quite similar to their ancestors, such as the tiny flying squirrel of the Far East.
This animal is quite small in size – no more than 14 cm in length, not counting the tail, and it is colored quite contrastingly, in black and gray tones. Unlike many species of flying squirrels, the upper side of the body of this species is lighter than the lower one, and only a white transverse stripe stretches across the throat from one cheek to another. Unlike flying squirrels of the Holocene epoch, it is a fairly sociable animal, quite tolerant of the presence of congeners, especially when searching for food – insects, seeds and berries. While feeding, groups of these squirrels number up to 15-20 individuals. During feeding, they exchange sounds – chirping, chattering and purring. If one of the animals detects an enemy, it emits an alarm signal, a high-pitched, high-frequency squeak well known to other forest animals. Nevertheless, despite their sociability, tiny flying squirrel does not form real flocks: each pair has its own nest (usually in a tree-trunk hollow), where the female raises cubs (from 3 to 6 in one litter). The male visits and feeds her; when the cubs of this species grow up, both parents begin to feed them; but when the young squirrels grow up and leave their parents, the pairs of adult animals also break up. One female is able to give birth and raise 4 litters during the year.
Tiny flying squirrel is not a territorial animal: when adult animals have no cubs, they simply migrate in the forest without permanent nests and spend the night in a new place each time. However, they stay within a fairly large territory, without going beyond its borders. The animals are well aware of the main shelters in this area. The enemies of this species are typical for arboreal rodents – these are birds of prey, especially descendants of corvids and predatory shrikes, as well as arboreal mustelids and viverrids. Tiny flying squirrel prefers to escape from them in the air, but its ability to glide is limited – it mostly glides in the air in a straight line, covering a distance of up to 5 meters in one jump. Due to its small size, it easily escapes from predators in narrow shelters.
Tiny flying squirrel can live on average 3-4 years.

Nocturnal flying squirrel (Eoglaucomus nocturnus)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: South Asia south of the Himalayas, subtropical and tropical forests.
In the mammalian world, rodents are among the best adaptation specialists; during their existence, they managed to occupy a wide variety of ecological niches, as well as acquire the ability to glide. In Neocene, these trends persisted, and rodents are still a thriving group of mammals.
Nocturnal flying squirrel is a typical representative of Neocene flying squirrels. Animals of this species are quite large: they grow up to 30 cm in length, not counting the tail, and weigh about 600 grams. Externally, and especially in coloration, this species resembles ordinary squirrels, especially if the gliding membrane is not visible. The animal has a reddish-gray coat, darker on the crown, shoulders, back and upper side of the tail. The throat, belly, and underside of the tail are ash-gray. The hands and feet are coal black.
The main feature of this species is its predominantly nocturnal lifestyle: during the day, this animal hides in tree hollows or in old bird nests, and comes out only if disturbed. But at night, the nocturnal flying squirrel actively runs on trees in search of food – mainly insects, less often small vertebrates or tree fruits. It has wide rounded ears, large sensitive eyes, and many vibrissae growing on its muzzle and above its eyes.
Nocturnal flying squirrels are hunted by owls, tree snakes, and sometimes by various carnivores. Nocturnal flying squirrel prefers to escape from them among thickets of branches and lianas – this animal is a good glider, but prefers to use this means of escape only in the most extreme cases. Due to its acute hearing, this animal easily detects the approach of most predators, and only owls with their silent flight manage to catch this animal off guard.
Nocturnal flying squirrel has no specific mating season – females of this species can be ready to breed at any time of the year, although their activity is slightly higher during the rain season. They leave odorous marks on the tips of the branches, which the males find while gliding. In addition, they call males with special sounds resembling a quiet buzzing. This animal does not form permanent pairs – only the female takes care of the cubs. The female gives birth to 3 broods per year. Pregnancy lasts about 3 weeks, and there are up to 7 cubs in a litter. For 2 months, the female takes care of the cubs, but at the age of six months, the young nocturnal flying squirrels are already completely independent and ready to breed. The average life expectancy of this species is no more than 7 years.

Leopard flying squirrel (Glaucomys carnifex)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: southwestern North America, dry mountain forests.
Flying squirrels occupy a rather unusual ecological niche in the animal world: these are mammals able to gliding flight, unlike chiropterans, which fly actively like birds. In other zoogeographic realms, they have analogues among other groups of mammals. Flying squirrels live mostly in the tropical forests of Eurasia. In Meganesia, flying squirrels are replaced by their marsupial counterparts; in Africa, gliding rodents from another family, the anomalures, live... But true flying squirrels are the only gliding mammals that managed to inhabit not only the tropics, but also temperate and even cold climates. They settled in the coniferous forests of Eurasia and North America, and it served them well in Neocene, when new species of these animals appeared.
It happened partly due to the catastrophic climatic changes of the end of Holocene and the beginning of Neocene, when the advancing glacier pushed the more northern species of flying squirrels to the south, forcing them to adapt to new conditions, and then retreated, returning the former living spaces to new species. One of the flying squirrel species of southern origin is leopard flying squirrel. It is a distant descendant of the American flying squirrels of Holocene epoch. This animal is of medium size by the standards of tree dwellers: 18 cm in length and the length of the tail is about 15 cm. The coloration of the back is usually straw yellow or deep brown with various transitional variants between them, and there are small white spots on it; the gliding membrane lacks spots. Tail is long and thin, the same color as the back, but lacking spots. The belly is of monotonous coloration, usually white or light yellow, depending on the intensity of the back coloration. The weight of an adult animal is about 175 grams: leopard flying squirrel is a very slender animal with proportionally large teeth and claws... And it is a predator.
Many rodents, including various squirrels, consume food of both animal and vegetative origin, but the leopard flying squirrel has turned to an exclusive predator that almost does not eat plant food, since its digestive system actually does not take such food anymore. This rodent lives in the mountain forests of southwestern North America, where the climate is quite dry and seasonal due to the “rain shadow” of the mountains, and plant food, especially greenery, is acceptable quite irregularly, while animal food is easier to find.
Leopard flying squirrel is active mainly at night: its large eyes work even in the dim light of the moon or stars; its hearing and sense of smell are also well developed, and its whiskers are very large and sensitive: even if it cannot see its prey, it will still be able to hear, smell or grope it in complete darkness. The leopard flying squirrel feeds on a variety of animals, from arboreal insects (longhorn beetles and grasshoppers) to small mammals and birds. In winter, this species hunts birds migrating from the northern regions of the continent. This rodent is very strong for its size, and brave: it bravely attacks even prey larger than itself, and kills it with several bites of long and thin incisors, holding it with its paws. The pads of the paws of this species are heavily cornificated and covered with transverse ridges and grooves: this feature helps to better hold prey and keep on trees. In addition, prickly cacti make up part of the woody vegetation in dry mountain forests.
During the day, leopard flying squirrel sleeps in a secluded place – in a hollow, in other animal’s nest, or somewhere deep in the branches. At this time, it is most vulnerable to birds of prey and tree snakes, which sneak up on it while it sleeps and quickly attack. At night, leopard flying squirrel usually easily escapes from enemies: it runs and climbs trees fast, and its gliding is also quite maneuverable and fast. But usually this flying squirrel uses gliding for a completely different purpose: to get close to its prey silently and attack from above.
The mating season of this species takes place in late September and early October, during rare winter rains, when vegetation becomes slightly more abundant and more prey appears. The cubs are born a little later, in November and December. There are from two to six cubs in the litter; they are hairless, blind and helpless. The female feeds them with milk, and later brings prey to the nest. The male does not take care of the cubs, and the leopard flying squirrel does not form permanent pairs either. Sometimes males can even eat the cubs if they find them without their mother. But the cubs grow up fast: after a couple of weeks, they already become somewhat independent and leave their shelter at night, exploring the surrounding area. At the same time, most of them die from the main enemies of this species – the local owl species. The mother, if she is nearby, protects them, doing it quite ferociously, but after a couple of months the survived and grown-up squirrel cubs leave their mother and begin to live independently.
Leopard flying squirrel is an animal with weakly expressed territorialism: it does not have a clearly defined territory, and the possessions of different animals overlap in great degree. Each individual remembers its territory well and knows several trees with hollows or large crowns where to spend the day. Nevertheless, sometimes several animals meet in the same shelter, and in this case the leopard flying squirrel treats its congeners with tolerance, unlike in cases when the male tries to attack the shelter with cubs.
The mortality rate of cubs and young individuals in this species is high. If the animal does not die in early age, then puberty occurs at the age of 4 months. The leopard flying squirrel can live up to 6-7 years.

South American flying squirrel (Glaucomys neotropicalis)
Order: Rodents (Rodentia)
Family: Squirrels (Sciuridae)

Habitat: northern South America, sparsely wooded areas.
Throughout the Cenozoic, flying squirrels and their anatomical counterparts from other orders of mammals were completely absent in South America. It happened so due to a number of factors. The ancestral flying squirrel species did not participate in the faunal exchange between the two Americas in the Pliocene-Pleistocene; perhaps the presence of marmoset monkeys was a deterrent to the diversity of arboreal rodents. In addition, the features of the forest canopy contributed to the appearance of tree-climbing forms rather than gliding ones. As a result, the first flying squirrels appeared in South America only after the end of Holocene, when they were driven there by a glacier, but before South America separated from North America again.
South American flying squirrel is one of the most chronologically young flying squirrel species in the history of the Earth of Neocene epoch. This is not a very large animal – the size of flying squirrels of the Holocene epoch, which lived in the Holarctic. Its wool color is not very bright, but mottled: the general background color is beige-gray with irregular spots on the back and upper side of the gliding membrane. The underside of the body is white. Tail is fluffy and has a black tip. The auricles are large, almost hairless, and mobile: the animal has acute hearing. In addition, the surface of the auricles helps the body dissipate the excess heat.
It is a tropical animal, which lives only in the northern part of South America, where the appropriate climate is preserved. The animal prefers forests in which the tree crowns do not form a continuous canopy, which makes it possible to avoid competition from climbing species. South American flying squirrel is a solitary rodent species. The territoriality of this species is poorly expressed, but the animals usually avoid each other, with the exception of the mating season, which in the southern hemisphere falls at the end of March-beginning of April. In May and June, the females of this species already have cubs, and by the following year, the young of this species can already produce offspring. During the year, the female gives up to 4 litters of 5-8 cubs, and raises them alone. This species does not form permanent breeding pairs.
South American flying squirrel is more herbivorous than other flying squirrels, and almost does not eat animal food. Instead, it consumes various plants and their parts –stems, leaves, buds, flowers and fruits. This flying squirrel can eat plant seeds that are poisonous to other rodents. It becomes prey to various birds of prey and carnivorous beasts, as well as large arboreal lizards. Therefore, South American flying squirrel is a nocturnal animal and spends the day in a secluded place, usually in trees. This animal prefers not to descend to the ground, because there are many enemies there and it takes a long time to climb the trunk to make one more gliding jump.
The average life expectancy of South American flying squirrel is 4-5 years; some individuals live much longer, but the mortality rate of cubs in this species is very high.

Californian false jerboa (Pseudodipodes californicus)
Order: Rodents (Rodentia)
Family: Heteromyids (Heteromyidae)

Habitat: California Island, open spaces.
Rodents, the most diverse and resilient of mammals, survived the human era with fewer losses than most other mammalian orders. Relatively few commercial and local species have disappeared among them. But the other ones survived successfully, evolved actively, and are as diverse in Neocene as they were in Holocene. After the age of man, California Island split off from the North American mainland, and its inhabitants had got their own unique evolutionary destiny. There are several endemic species among the local rodents, one of which is the false jerboa, a descendant of Merriam’s kangaroo rat (Dipodomys merriami).
Compared to its ancestor, this beast has become large: the body length is 50 cm, the tail is 33 cm. The wool color varies significantly individually, from black and brown to yellow; the belly is always grayish-white. It is a nocturnal animal with large eyes and wide rounded ears. To the detriment of hearing and vision, the brain size is very small; the animal is timid and easily panics. At night, the animal moves in long leaps during the feeding, and during the day it sleeps in bushes, among cacti or in dense grass. This species feeds mainly on seeds of varying degree of ripeness, sometimes on tough grasses. The feeding area forms a circle with a radius of up to 2 km from the daytime location; the individual territories of the animals overlap greatly. In search of food, the animals form temporary groups of up to 10 animals. During feeding, the animals stay close to the bushes, hiding in them if something threatens them. Natural enemies are local owls and snakes.
The breeding season lasts from March to May. No permanent pairs are formed, and several males can mate with one female. There are usually 3 cubs in a litter – they are well-developed and sighted, but in the early days they are almost unable to actively move and just stand on their feet. The female hides them in the thicket, bringing them to a new shelter every 2-3 days. At the age of 1.5 months, the cubs begin to eat the seeds – first partially digested, which their mother regurgitates, then independently found ones. Young animals become independent by autumn, being mature the following year. Life expectancy in nature is 10 years.

Farmer hamster (Agrocricetus agricola)
Order: Rodents (Rodentia)
Family: Hamsters (Cricetidae)

Habitat: steppes of Southern Europe (Three-Rivers-Land) to the east up to Southern Ural and Central Asia.
Rodents are the most numerous global widespread order of mammals. Their species increased variety till all Cenozoic era and had got advantage in Holocene. Human economic activity in many cases promoted prosperity of rodents. People superseded and destroyed wild hoofed mammals, ploughed steppes and cultivated large plantations of graminoids. People had also exterminated many feathered and four-footed predators, and it had favoured to breeding of separate species of rodents. They grasped new habitats freely, getting of advantage from human activity.
In Neocene extensive spaces in Southern Europe, Middle and Central Asia had turned to grassy plains in which local herbivores graze. Their typical representatives are steppe species of harelopes and massive porcippula similar to heavy-build pony. They “cut” steppe grasses by teeth, but do it not everywhere. Here and there in steppe sites are located, where the grass is much denser and higher rather than usually. Graminoids in these places differ in rather massive ears rocking in the wind – it is a separate species, the descendant of feral wheat many MY ago cultivated by people. These thickets differ in strict monotony - among them plants of other species are practically absent. Obviously, these plants were specially selected and carefully protected - such sites are precisely separated from other grasses. Local herbivores for any reasons avoid eating this grass which looks much more appetizing, than everywhere.
The puzzle is disclosed very simply when among high grasses there are small stumpy mammals with rich longitudinal – striped fur of gray-brown color. It wanders in thickets of high grasses, from time to time stopping and breaking off stems lasting among grasses. This is one decision of some puzzles at once: the rodent really looks after this graminoids. Actually, these thickets represent its extensive fodder site. And due to it the animal is named farmer hamster.
This animal is a little bit smaller, rather than common hamster (Cricetus cricetus), the usual inhabitant of Eurasian steppes of Holocene epoch. Probably, it is its descendant though it is possible, that its ancestor could be one of small species of Central-Asian hamsters. Colouring of farmer hamster combines two patterns. The top side of body of this animal is cryptically colored: on gray-brown background narrow black strips stretch. Having dropped to the ground, this animal becomes completely imperceptible from afar for feathered and four-footed predators. Coloring of stomach strongly differs from coloring of the back: on stomach and cheeks there are wide cross black strips on white background. This coloring becomes appreciable from apart when this small mammal rears to eat something or simply to look round. At this animal there is constitution typical for hamsters: large head, short thick trunk and very short tail, hardly appreciable among wool.
This mammal differs in unique strategy of survival. It not simply gathers seeds of plants which serve as food to it, and specially creates conditions for their growth. It carefully keeps up a site of steppe around of the hole and in summer selectively eats plants which do not belong to graminoids. As the result at the “allotment” occupied by this hamster amounting about one hundred square meters graminoids grow well, providing the hamster by grain for winter. More often at sites of farmer hamster the hamster wheat grows – it is the special genus of graminoids again “cultivated” by the hamster after people and actually entered symbiosis relations. In summer seeds of graminoids have not ripened yet, and animal eats grass – weeds growing at its site. Also it eats various insects, involuntarily relieving fodder graminoids from wreckers. In the autumn when seeds of grasses ripen, farmer hamster gathers “crop”: it chooses the ripest ears and carefully husks them, scattering dust on site and carrying off in burrow well cleared grain. Gradually at the territory “cultivated” for a long time graminoids start to grow especially well, and obviously prevail of other plants.
Farmer hamster also fertilizes ground with dung – it does not have specially removed “toilet”, and the part of mineral substances comes back in ground with its dung. Only in winter it leaves dung in special chamber of hole, and throws it out outside in common with used litter in spring - it additionally fertilizes ground in the territory this way.
Well-groomed sites of these mammals are favourite object of attention from the part of other grain and grass lovers. At sites of farmer hamster in autumn birds feed, and large herbivores occasionally visit them. But the farmer hamster can render their repulse: despite of small growth, it is very much martial creature. It frightens off smaller pilferers by loud squeals and high jumps. Thus small mammal strongly puffs cheek pouches to seem larger. Such reception does not work against the large herbivorous animals: they are strong enough simply to crush this animal by hoof. But the hamster uses one more effective means of protection against them: it lies down on back, showing to the uninvited visitor contrastly colored belly, and shrilly squeals. If threat has not worked, it sprinkles to the stranger stinky substances from strongly advanced anal glands similarly to skunk.
The specific habit of life had transformed this animal to even greater “homebody”, rather than hamsters of Holocene epoch. But it does not avoid the society of neighbours, and prefers to settle in rarefied colonies. In total “allotments” of different individuals of this species gather to the colony rather closely to each other - their borders are divided with some meters. In the center of colony there are “allotments” of strongest individuals – they are richest and better protected from herbivores. But in the centre of colony lack of place is sharply felt, and for each superfluous plot of land a real battle takes place. Individuals at edges of colonies feel first that they are not unique local herbivores. But it is possible for them to expand their “allotment”, having “cultivated” more parts of steppe. The certain balance and order in a colony is reached so.
Outside of breeding season each individual diligently marks borders of the territory, sprinkling on grass secretions of anal glands. Only being ready for pairing the female can leave the site to meet the male – in any other time it would meet her with bites of sharp incisors. In courtship season the fodder site is an original secondary sexual attribute: the female chooses the male for pairing looking the size and “cultivating” degree of its allotments. After pairing female returns to the site and rears posterity itself. Within one summer the female rears two – three hatches of 4 – 6 cubs. The most part of young animals settled from colony can not find suitable site, and perishes in teeth and claws of local predators. To the autumn survived young hamsters find site for life, and gather in hole the first stock for winter – basically seeds of wild-growing grasses. In autumn the farmer hamster fattens up intensively and grows fat strongly: fat may make up to half of weight of animal.
In winter farmer hamster falls into deep hibernation: the temperature of its body is reduced practically up to an ambient temperature, and pulse decreases up to several beatings per minute. Some times for winter animal wakes up to eat some of seeds from the stocks. It is awake till some hours, yet will empty intestines completely, and then falls runs into hibernation again.
Though farmer hamsters are convinced and bilious egoists, all of them keep the contact with each other: between their holes there are burrows connecting them to whole system. To tell the truth, more often other steppe animals dig these courses, but hamsters willingly use them. In such tunnels animals leave from chasing of predators. Being on the ground surface, animals “communicate” with each other with the help of whistling, as suslics. In such way they warn each other of occurrence of predator – usually steppe eagleraven or predatory mammal zibetonyx hunt them.
The biggest complexity in life of farmer hamster is derivated by its habit of life, to be more exact – by the way of “agriculture”. At their sites only the unique species of graminoids frequently grow, therefore animals endure heavy time when cultivated plants are attacked with illnesses and parasites. On “hamster wheat” the ergot fungus grows often. But small ergot infection of graminoids does not harm to animal – when this fungus appears, hamster specially searches for such ears, chews fungus off from them eats. Ergot poison renders intoxicating effect to these rodents – in the beginning animal becomes easily excitable and aggressive, then gets into the hole and sleeps for a long time. The activity of farmer hamster constrains the distribution of ergot, but at mass disease of graminoids they can not cope with it, and the part of crop perishes. After flare up of plant desease in colonies of farmer hamsters the famine comes, and number of populations may decrease in tens times. And in such situation the part of colony members simply leaves on new places where new “plantations” appear in some years.

Whistling hamster (Buccacricetus stridor)
Order: Rodents (Rodentia)
Family: Hamsters (Cricetidae)

Habitat: steppes of Tree-Rivers-Land, thickets of grasses.
Some species of rodents had received great advantages in survival in human epoch. Expansion of agricultural areas had allowed them to settle widely; the cultivating of cereals had provided constant and uninterrupted source of food, and human presence and its activity had strongly reduced number of predators in habitats of rodents. Disappearance of mankind has restored natural balance of environment during several hundreds thousand years – the extensive areas of monocultures had disappeared, predators had appeared, and gradual formation of new ecosystems instead of ones destroyed by people began. Evolution had gone in the natural way again, and at new species of animals new adaptations for survival began to develop.
In extensive steppes of Tree-Rivers-Land reaching along northern and eastern coasts of Fourseas, rodents are prevailing group of mammals. Quickly evolving, they had formed many species, differing by requirements to inhabitancy. Representatives of hamster family differ from other rodents by ability to gather the large stock of forage for winter. One of their species, farmer hamster, even is engaged in original “cultivating” of one species of graminoids on its fodder area. But other hamsters lead more traditional way of life.
Many predators live in steppes. One of widely widespread species is zibetonyx, cursorial species of viverrids, the most northern species of this family. It represents danger to many small rodents, but one of the large hamsters, living in steppe, is not afraid of its attack: it is armed with sharp incisors and is able to protect itself. This species is whistling hamster.
Whistling hamster is rather large rodent: the length of its body is about 40 centimeters, and weight reaches 2 kgs. By appearance it is similar to other hamsters: it is short-legged and massive one with large head. Its wool on back, nape and top part of neck has camouflage color – golden-yellow with darker faltering longitudinal strips. The bottom part of body sharply differs by colouring: stomach and forward part of head are white with sparse black spots.
The most remarkable feature of whistling hamster is its cheek pouches. Usually they are used for dragging stocks of forage to the hole, but at the attack they are used in completely unusual mode. The aggressive animal rears on hind legs and starts to puff cheek pouches. Their skin is very extensable, and due to it this rodent seems larger and more impressive. And then remembered colouring of wool is expressed in full degree – on skin covering cheek pouches - cross-striped pattern becomes visible. Skin under wool is also pigmented at the places where black hairs grow; therefore this pattern stays appreciable, even when cheek pouches are puffed completely. This is the first warning to predator. Usually it is enough to the skilled predator to stop getting into touch with this rodent. If attempts of attack proceed, hamster contracts ring muscles encircling cheek pouches, and blows them off. Thus loud whistle is hearing. This is more powerful prevention to predators. After that hamster rushes on the enemy and seizes it by incisors. It happens, these animals attack even porcippulas – large and harmless herbivores.
Whistling hamsters live solitarily in rather extensive territories – between holes of separate individuals there is a distance not less than 200 meters. Warning relatives that the territory is occupied, the owner of territory whistles from time to time, puffing cheek pouches. Having heard its whistling, neighbours usually also respond.
This hamster gathers seeds of graminoids in its extensive individual territory, and to the end of an autumn it gathers in underground “pantry” up to 30 kgs of grain. In addition to it, animal digs out and eats tubers and rhizomes of various plants, a part from which it also drags to “pantry”. To winter this hamster is strongly eaten off and runs into hibernation when autumn rains begin, changed further by light frost and snow. For winter it wakes up many times and eats a part of the stocks. In spring whistling hamster searches mushrooms growing in steppe, and eats up the rests of winter stocks. Usually they suffice up to growth of young grass.
In spring the courtship season begins at these rodents. Demonstration of puffed cheek pouches and whistling are important elements of courtship ritual of whistling hamster. Usually male comes itself to the territory of female ready to pairing and starts to court after her, following her with blown up cheek pouches and whistling. If near one female some males meet, they arrange a kind of “duel”, trying to whistle louder and longer, than the competitor. If it does not help to define superiority, combat begins.
Within one year the female gives rise to 2 litters of 3 – 4 cubs. Young animals of the second litter winter together with the female and in common prepare forage in autumn. The young growth of summer litter has time to find territory suitable for life, to dig a hole and to prepare enough amount of food for successful wintering. The next spring young animals from both litters can take part in breeding.

Sirtia (Sirtia socialis)
Order: Rodents (Rodentia)
Family: Hamsters (Cricetidae)

Habitat: Siberian forest tundra, meadows.

Picture by Pavel Volkov

Among lemmings, a number of species easily survived the anthropogenic impact – small animals with a rapid rate of generational change easily retained sufficiently large populations, and their adaptation to the extreme conditions of the polar regions allowed them to maintain high numbers during the Ice Age. New species of these rodents, including forest-dwelling ones, have evolved in Neocene. And some species became larger during the Ice Age, but with the warming of the climate, only one of the large descendants of lemmings survived – sirtia, a descendant of the Arctic lemming (Dicrostonyx torquatus).
Compared to its ancestor, sirtia is a large species: the body length is 20-25 cm, the weight is up to 700 g, and by winter the animal grows fat to 1 kg. It is a stocky, short-legged animal with a large head. Its digits are short, equipped with a well-developed corneous layer on the underside of the feet and hands. By winter, this layer thickens significantly. The ears are small and rounded, hidden in the fur; the eyes are small, shifted to the top of the head. The tail is absent. The wool color is brown or black, and sometimes gray. There is a large white spot on the animal’s cheeks and throat.
It feeds on grasses, mosses and rhizomes, and occasionally eats insects or eggs of birds nesting on the ground. Food of animal origin is usually eaten by pregnant and lactating females. They live mainly in colonies: 12-15 pairs of adult animals and their cubs (hence the name: “Sirtia” is an underground folk in the mythology of the Nenets). The colony’s dwelling is a system of underground tunnels at shallow depths, with separate living chambers for families and deep-lying storage chambers. There are always several disguised emergency exits in the colony. Like its ancestor, sirtia stores food for the winter – usually dry extra grain seeds and roots. When feeding, these animals are very cautious, constantly looking around and sniffing. In spring and autumn, they come to the surface of the earth exclusively at night, but in the polar summer they feed at any time of the day. In winter, animals spend a significant part of their time sleeping, and only occasionally wake up to eat. The animals also restore tunnels and dig vents for ventilation of the burrow system.
The breeding season begins in April-May, when the animals recover from wintering. No permanent pairs are formed; the female manages to mate with several males. Pregnancy lasts 21 days, and there are up to 6 cubs in a litter. Lactation lasts 1 month, and then the young animals pass to adult food. At this time, the female manages to mate again and bears a new litter; thus, she can give 2 litters per season. In the spring, the young leave the colony to join their neighbors or establish their own settlement. Puberty occurs in the spring of the following year. Life expectancy is up to 5-8 years.

Shy lemming, maachis (Lemmus petronia)
Order: Rodents (Rodentia)
Family: Hamsters (Cricetidae)

Habitat: Fennoscandia, the islands of the Arctic Ocean – Solovetsky Islands, Svalbard and Novaya Zemlya.
In the human epoch, lemmings proved to be quite successful rodents. Being numerous and fast-breeding, they easily survived the age of man, and only a few species (such as the Norway lemming) became extinct during the Ice Age. By the time the ice retreated, they were spread over a larger area than in the human era, and later some of their species adapted to the new conditions in their new habitat. But the descendants of the West Siberian lemming were among those who returned to the old territories, following the usual living conditions. One of them is the maachis, which lives in the north of Eurasia.
Like its ancestors, maachis is a small, fast-breeding rodent. The body length of an adult is about 8 cm. It is an animal with a large head, short legs and an almost absent tail. The wool color is grayish- or reddish-brown, sometimes rusty, brown or black. With any of the background coloration versions, there is a gray spot on the neck and chest of the animal that resembles a beard (hence the name: Finnish earth spirit, gnome). The beast is active both day and night, alternating rest time with periods of activity.
Shy lemming feeds on herbaceous plants, moss, seeds, berries and insects. It lives in colonies, but is very cautious: only occasionally it is possible to notice individual animals rising on their hind legs to explore the surroundings at the entrances to their shelters. Animals warn their congeners about the danger with a high-pitched squeak on the verge of ultrasound. In search of food, animals try to move along their trails in the thickets of polar plants, showing themselves at the surface of the earth as little as possible. Wintering takes place in nests under the snow, at a depth of up to 1 meter. The nests are lined with dry plants and lichens. At the end of the polar summer, the animals bring a supply of seed pods, seeds and mushrooms to their wintering grounds. The “storerooms” are located among the stones, where they are more difficult to excavate, but at a shallow depth, so they are stored in the cold.
Under favorable conditions, this rodent can breed all year round, although in winter mating occurs less frequently. When fighting for females, males jostle each other with their heads, squeak and chase each other. Pregnancy lasts for 20 days, and there are 6-8 cubs in the litter. They grow very fast: they feed on milk for a week, at 3 weeks they are already independent, and at 5 weeks they are sexually mature. Females from the first broods of the season already give birth to their own offspring by the end of summer. Life expectancy is up to 5 years. Maachis has numerous enemies – birds of prey and carnivorous mammals, and on the southern edge of its range, there are also snakes and large amphibians among them. The cubs can be stung and eaten by ants. However, the number of maachis can increase drastically every few years. When there are too many of these lemmings, they move to other places in great numbers, often crossing rivers and even swimming out to sea. Some of these animals manage to reach remote islands, but their majority dies from predators.

Japanese ratbeaver (Pseudocastor ergaster)
Order: Rodents (Rodentia)
Family: Hamsters (Cricetidae)

Habitat: mountain rivers of Japan Archipelago.

Picture by Pavel Volkov

Human activity has left noticeable marks in the fauna and flora of the world. This is not only the extinction of certain species, but also the appearance of various species of living creatures in places where they could not have appeared naturally. One of these species was the North American muskrat (Ondatra zibethica), which was widely settled by humans in Eurasia. During the Holocene-Neocene glaciation, this rodent substituted the beaver, whose numbers declined due to human activity. In Early Neocene, the descendants of the muskrat increased in size and became ecological analogues of beavers. They developed similar construction skills, allowing them to build dams and create shallow reservoirs, which became the core for the formation of a highly productive ecosystem. Due to volcanic activity that created isthmuses between the Pacific islands off the Asian coast, ratbeavers were able to penetrate into the territory of the Japan Islands, where they evolved into a separate species, Japanese ratbeaver, when appeared in isolation.
Insular habitats have influenced the appearance of this species. The body length of this species is about 40 cm, and the weight is up to 10 kg. The tail of this animal is about the length of the body, flattened, wide and covered with hairless skin; only along the upper side of the tail stretches a patch of skin covered with hair. The hind legs are equipped with webbing and armed with strong claws. The animal has a fairly massive skeleton and a strong wide skull, flattened from above. The wool is thick, black in color with a “gray streak” of long white over hairs on the nape, back and sides. However, in some mountain ranges and on small isolated islands there are families and entire subpopulations having a different wool color, ranging from light gray to fawn and rusty-red. The skin under the wool is dark: the tail, paws, nose and ears are black, even in individuals with abnormally light hair. Nostrils, small eyes and short ears are shifted to the top of the head – it is typical for an animal that spends a significant part of its life in the water.
Japanese ratbeavers live in family groups consisting of a breeding adult pair and their cubs of the last two broods. This species inhabits turbulent rivers with a fast current: its massive build, strong claws and heavy bones help this animal stay in the current. This species inhabits rivers throughout the archipelago, rising even into rough mountain rivers.
The specifics of the habitat – a fast strong current – left its mark on the peculiarities of the animal’s building activity. This species prefers to build dams using stones. The animal’s strength is enough to roll stones weighing twice its own weight. When doing it, the beast leans against the stone with its solid skull and pushes it. Sometimes adult animals learn how to work with a stone by moving it with their combined efforts, but young animals have to learn this on their own.
The construction of the dam begins with blocking the riverbed with several large stones. Then the animals pile stones the size of apples between them, and when the current slows down enough, they plug the holes in the dam with tussocks of grass torn with ground on their roots, branches and earth. As the water level rises, the animals build up additional dams in some places in the neighborhood until the water level rises high enough to build a den. The dwelling of this species is a lodge made of grass and branches, which is built on a piled up islet in the middle of a flooded section of the river valley. It also has an underground outlet to the water, as well as 2-3 chambers for animals of various ages. In a pond fenced off by animals, cattails and arrowheads begin to grow abundantly, the underground parts of which are loved by ratbeavers. They also willingly eat the rhizomes of water lilies and the tender greenery of many marsh plants. Frogs, ducks and grebes settle in ponds created by ratbeavers. As ponds overgrow, trees of various species settle on them. Numerous generations of Japanese ratbeavers have transformed mountain river valleys into a kind of terraced forests.
Once a year, a female gives birth to up to 5 well-developed cubs. At the age of two years, they become sexually mature and leave their parents’ lodge, often settling upstream or downstream. The life expectancy of this species reaches 20 years.

Ratcoon (Amphimorphodon procyoniformis)
Order: Rodents (Rodentia)
Family: Predatory hamsters (Carnincisividae)

Habitat: southwestern North America, semi-deserts, dry forests and shrubby thickets.

Picture by Wovoka

The beginning of Neocene was a time of significant biospheric changes, extinctions, and extraordinary evolutionary decisions. Many groups of animals and plants became extinct completely, thereby giving previously unnoticed groups of living organisms a chance for an evolutionary breakthrough. So, in the Old World, catshrews and specialized predatory descendants of hedgehogs evolved – such a situation somewhat resembled the beginning of the Cenozoic, when carnivorous species appeared even among ungulates. However, these new predators very often have rather primitive brains, so they generally lose the struggle for existence to true carnivores (Carnivora) and are represented by rare specialized species only.
A similar evolutionary experiment has also been realized in New World: a new group of mammals has appeared in North America – predatory hamsters (descendants of flesh-eating grasshopper mice Onychomys). These are mostly small and medium-sized animals; they live in the shadow of true predators, but they are able to compete with them quite successfully. Ratcoon is the largest member of this family.
Ratcoon is a medium-sized animal: 50-60 cm long, 25-30 cm tall, weighing about 12 kg. Like the common raccoon of Holocene, it is a fairly tightly built and stocky animal, omnivorous with a predilection for carnivory.
Its hind legs are slightly longer than the forelegs, so the ratcoon can move only on them for a while, making jumps, especially in the process of catching prey or escaping from predators. At such moments, it resembles a wallaby of the human era.
Forelegs with well-developed fingers are equipped with sharp claws, with which the beast captures its prey. The animal resembles a raccoon in its ability to manipulate objects with its front paws.
The tail is inflexible, covered with short hair and thick – it serves as a storage for fat, as well as a balancer during the movement (as in some jerboas).
The coloration is variable, and there are several color morphs. In a typical case, the wool is gray with small specks on the back and nape; on the belly, the shade is lighter. Depending on the color of the prevailing soils, the wool color varies from dark gray to sandy yellow, and there are melanists also. In animals of both sexes, there is a white spot on the underside of the neck, bordered by darker fur.
The ratcoon’s head is large, with high cheekbones and a shortened muzzle. The wide rounded auricles help the animal cool down in the heat – the animal lubricates them with saliva using its paws. The eyes are small, pointing sideways and forward, and the vision is partially stereoscopic. The nasal cavity is extensive, and the olfactory epithelium forms numerous folds, making the sense of smell very acute.
Incisors have a special structure – they are of piercing type, narrow and thick. The enamel forms a series of thickened stripes, which give a jagged cutting edge when the edges are ground off. The diastema is shortened. The anterior molar is curiously modified: it is equipped with a cutting outer edge. Other molars have pointed cusps.
With a bite, this beast can crush bones, causing serious wounds to attacking predators. Warning of its readiness to defend itself, the beast stands on its hind legs and emits a hoarse squeal, opening its mouth and showing incisors and a white spot on its chest. It attacks the enemy, snapping his teeth, and usually successfully defends itself from ground-dwelling predators. Only birds of prey are able to catch it off guard and kill it by attacking from behind.
Thorny shrubs, cactus thickets and burrows up to 3-4 meters deep serve as a shelter for this animal; the animal hides there in the daytime heat, and the female raises offspring there.
The ratcoon’s main prey is small animals: reptiles, birds and mammals, and various invertebrates. If necessary, the ratcoon is able to kill prey weighing more than itself – up to 20 kg. The beast inflicts a deep penetrating bite on live prey, tearing the insides. Even after escaping from its teeth, the prey bleeds out, having received deep wounds. In addition, the ratcoon readily eats carrion, and even drives away small predators from their prey. The animal does not refuse plant food, especially when it is found in abundance, but prefers fruits and large seeds with thin skins. With narrow incisors, it is difficult to dismember prey, so the ratcoon bites off pieces of its prey using the cutting edges of the front molars.
Ratcoon is an uncommunicative animal, especially males who prefer to live alone. The ratcoon does not form mating pairs either, and courtship in this species is rather fleeting: having found a suitable female ready for mating, the male cautiously approaches her, and begins to “coo” from afar, standing on his hind legs and showing spot on his chest. Quick mating follows; ratcoons do not form permanent breeding pairs.
Pregnancy lasts about a month. There are 4-5 blind and sparsely furred cubs in the litter. Only the female takes care of the cubs; males can easily eat their own offspring. At the age of one month, they already reach a weight of 500 g and gradually begin to try to hunt invertebrates and lizards. Half-year-old animals begin to lead independent lives, but not all of them survive to the puberty (at the age of 2 years) – up to half of the young die at this time. Adult animals that can defend themselves have fewer enemies.
With an abundance of food, adult animals are relatively tolerant of each other, but females and their offspring fiercely guard the territory around the nest. Ratcoons become prey to larger hunters – lupardus, golden nev and marabou vulture. Ratcoon is quite strong for its size and fiercely resists, so only sick, old or young individuals usually die from predators. The young in the nest are often eaten by large lizards and snakes.
The average life expectancy of a ratcoon is 18 years.

Ayapuh (Pseudolutra ayapuh)
Order: Rodents (Rodentia)
Family: Neoichthyomyids (Neoichthyomyidae)

Habitat: the south of South America, Tierra del Fuego, Pacific coast.
In human epoch otters were the basic predatory mammals of fresh water reservoirs. These animals were widely settled at all continents, except for Australia and Antarctica. One species of otters had developed sea habitats in northern part of Pacific Ocean. But in human epoch destruction of habitats and hunting for otters for the sake of fur had reduced their number in great degree, and they had not survived to Neocene. After human disappearance at various continents the ecological niche of otters was occupied by animals from various systematic groups. In South America otterodents, descendants of fish-eating hamsters of genus Ichthyomys, became the most successful ones in development of aquatic inhabitancy. Various species of these large carnivorous animals have mastered reservoirs of various types, from tropics up to Tierra del Fuego.
Ayapuh is one of otterodent species, which, as against the majority of species of this group, lives in brackish and sea water. The name of this animal is a name of otter from fairy tales of Indians of Tierra del Fuego. Ayapuh does not concede Amazonian otterodent in length, but differs in more massive and thickset constitution. It has short and wide tail of rounded outlines, large body, short neck and heavy head: it is connected to necessity of heat preservation in conditions of colder climate. Fur of ayapuh has rusty-brown color; at separate animals lower jaw and throat are white, but more often between forepaws there is only small white spot. Fur of ayapuh is very rich. The animal looks after it for a long time and greases it plentifully with secretions of glands located in armpits. Due to care fur gets additional water-repellent properties and keeps the air layer saving animal from overcooling under water in winter time.
Hands, feet and tail of animal are covered with short thin hair, and through naked skin animal could lose a lot of heat. But in paws and tail blood vessels form a countercurrent system which helps to keep heat.
The dental system of ayapuh is typical for rodents – it includes two pairs of sharp incisors of reddish-orange color representing its main instrument of getting of food and protection against enemies. The length of incisors in lower jaw of animal reaches 7 centimeters. For search of food ayapuh can dive to depth up to 20 – 30 meters. Swimming under water, animal makes wavy movements by backbone in vertical plane. Main movement bodies at this species are flattened tail and webby hinder legs. Animal uses forepaws to feel sea bottom and to overturn stones in searches of prey. Ayapuh frequently hunts near to large herbivorous mammals algoceti when families of these animals are fed in thickets of seaweed. At this time ayapuh catches fishes and crustaceans frightened at movements of giants. Also strong teeth allow ayapuh eating echinoderms – sea urchins and starfishes.
Under water animal searches for prey with the help of sight, but in muddy water or in twilight it uses long sensitive whiskers.
Ayapuh is social species: this animal settles at sea coast in small groups including up to five breeding pairs and several single individuals, young or old. Breeding pair at ayapuh forms to some breeding seasons, and sometimes is kept till whole life. Animals look after one after another, clearing fur of the partner, or feeding it up with a part of prey.
In storm ayapuh hides between stones and in natural shelters like caves. Only for posterity care female builds a hole, digging it with the help of forepaws. It frequently simply digs holes built by sea birds, expands and converts them.
Once a year, in spring (in Southern Hemisphere in October – beginning of November), female brings posterity – from two to four blind and deaf cubs covered with short wool. They quickly acquire rich wool, but begin to hear only at the age of 5 days, and eyes open at them at the age of 8-9 days. At monthly age cubs start to leave their shelter; and bi-monthly ones study swimming. At the age of two years young female is ready to breeding. Life expectancy reaches 17-20 years.

Fierce, or tiger-striped gerbil (Postrhombomys ferox)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: steppes of Central Asia, treeless areas.
Like most animals, gerbils lost some of their species during the time of human domination. However, they not only outlived humanity, but also easily regained their numbers during the subsequent Ice Age. In Early Neocene, gerbils gave rise to a group of new species that at one time competed with other large rodents and the then-emerging hoofed lagomorphs. Their rapid evolution was stopped only by the melting of the glacier and the establishment of more humid and less harsh climate on Earth, accompanied by the spread of humid steppes: gerbils hardly parted with their usual arid habitats. Only a few of them settled in the humid steppe regions. One of these species is the fierce gerbil, a descendant of the great gerbil (Rhombomys opimus).
This species is a relatively large representative of the group: body length 30-35 cm, tail – 12-15 cm, adult weight – 1.5-2 kg; males are larger than females. This rodent species has a very characteristic wool color: dark ochre-red with gray transverse stripes. At the end of the tail there is a tuft of white hair, which serves to provide visual signals to congeners. This species lives in open areas of the steppe, avoiding thickets of shrubs and the shores of reservoirs.
Fierce gerbil settles in colonies of up to 20 pairs of animals. Colonies of fierce gerbils represent a system of burrows connected to each other and dug in dense soil. Most of the animals in colony are busy gathering food during the day, but some of the animals are always alert, warning colony members of danger with a sharp barking call. When the colony size becomes large enough, the colony members themselves pounce on the enemy with a loud growling sound, driving away even the running monitor, cat- or fox-sized predatory mammals, herons and small owls. In fact, a predator can only catch an animal of this species far from the colony; due to this circumstance, the survival rate of the offspring of the fierce gerbil is very high, and the highest percentage of mortality of young animals occurs at the time of the beginning of independent life.
As food, fierce gerbils prefer cereals, wormwood and other plants with hard stems, as well as tubers and bulbs, which are found when animals dig their holes. For the winter, each adult animal stores plants in a burrow – up to 25 kg in dry form.
The mating season of this species takes place in March-April. At this time, quarrels often break out among the males, and they box, standing on their hind legs. Pregnancy lasts 30-35 days; usually there are 3-6 cubs in the brood. They are born blind, opening eyes only on the 13th day; at the age of 25 days they begin to taste grass, and at 30 days they finally switch to adult food. At the age of one year, some (up to half) of the young animals, due to persecution by adults, move to another colony or form a new one on the borders of the parent colony’s possessions. Puberty occurs at the age of 10 months, so some females go to look for a new colony while already pregnant. Life expectancy is up to 8-9 years.

Arabian burrow-digger (Parameriones communis)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: deserts and semi-deserts of Arabia.

Picture by Pavel Volkov

Rodents have shown significant evolutionary success throughout the Cenozoic. The key to this was their short life cycle, the ability to reproduce quickly and produce numerous offspring. Therefore, they relatively easily survived the ecological crisis at the turn of Holocene and Neocene, and in Early Neocene they rapidly evolved, occupying ecological niches vacated as a result of mass extinction. Their evolution, however, continued also in ecological niches previously occupied by them – some species disappeared, others came to replace them.
Gerbils were one of the successful groups of small rodents. Despite some losses, they survived the age of man. During the Ice Age, with the expansion of the areas of the arid steppes, they experienced a brief heyday. The Sundevall’s jird (Meriones crassus) turned out to be one of the successful representatives of this group, becoming the ancestor of a whole bunch of new species. One of them is Arabian burrow-digger, which inhabits the treeless spaces of the Arabian Peninsula.
Compared to the ancestral species, it is a relatively large rodent: body length – 35-45 cm, tail – 15 cm, weight – 3.2-4.2 kg. It has a solid build, a large head, and its hind legs are slightly longer than its front legs, which makes its back sloping. Because of this, the animal often moves by jumping on its hind legs, only occasionally touching the ground with its front paws while running. The ears are large, rounded, and abundantly pierced with blood vessels – heat irradiation takes place through them; there are no sweat glands in the skin. The coat color is sandy yellow with lighter or darker individual variations.
This animal feeds on various parts of most desert plants, including seeds, roots, tubers, leaves and fruits, and avoids only feeding on poisonous plants like milkweeds and dogbanes. Occasionally, this species eats insects.
Arabian burrow-digger lives in colonies of 12-15 breeding pairs. Each pair owns a burrow with several exits. The burrows of colony members are often connected and animals can move from one burrow to another, crossing a significant part of the territory of colony underground. Arabian burrow-digger is active at night; during the day, hiding in a burrow, the animal plugs the entrance from the inside with an earthen or vegetable stopper to keep the burrow cool during the daytime. When there is a shortage of plant food in lean years, it goes into dormancy, which lasts up to 2 months.
The mating season is associated with the frequency of rainfall and falls in winter. Burrow-diggers manage to bring 2 litters – at the beginning and end of the rainy season. Pregnancy lasts about 40 days, and there is 1 large developed cub in the litter. It is blind at birth, but it develops rapidly: it opens eyes on the third day, begins to taste adult food at 2 weeks, and stops sucking milk at 3 weeks. At this time, its mother is already pregnant again. The older cub helps to take care of the younger one, which contributes to the survival of the offspring. Puberty occurs at 7 months, and when the youngest cub matures, they both leave the burrow and the colony. Usually, young animals from different burrows settle together, digging temporary shelters for the night. At this time, many young animals die of starvation and predators if they do not join another colony or form a new one in a habitable place. Life expectancy is 10-12 years.
To the north, in the steppes and foothills of the Middle East, a larger (50-60 cm) Syrian burrow-digger (Parameriones levanticus) lives. This species has gray wool with a bluish tinge and a white spot on the tip of the muzzle. Unlike the Arabian species, it is pickier in food, preferring cereals and storing grain for the dry season.

False porcupine (Pseudoerethizon laterispinus)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: the jungles of Zinj Land.
Numerous and well-protected, African crested rats (Lophiomys imhausi) of the Holocene epoch survived the human era with few losses: the reduction of the forest area at the end of the human epoch and the Ice Age led to a disruption of the population of this species into several smaller parts. As a result, the descendants of the crested rat occupied several different niches by Neocene. One of them is the false porcupine, which has preserved and enhanced the protective adaptation inherited from its ancestor.
False porcupine is a relatively large rodent, but it is inferior to the caviomorph giants of South America, and even to cataphracterium, its neighbor. The body length is about 50 cm, the tail is 27 cm long, and the weight is up to 4 kg. The wool color is brown or black with white or yellowish specks on the coat. False porcupine looks like a slimmer version of its Holocene namesake: it is a four-legged animal with a massive head. A mane of highly elongated coarse hair stretches along the back, and tufts of similar hair grow on the shoulders of the beast. In these places, short and thick spikes with a porous surface are hidden among the wool; they are loosely attached to the skin when fully formed. In case of danger, the beast ruffles its fur, trying to look bigger, and growls, opening its mouth wide and showing its incisors.
This animal is a loner, although occasionally there are pairs ready to breed or females with their cubs. False porcupine feeds on plants, mainly leaves and tree-dwelling epiphytes. While eating, the animal sits on its hind legs, holding food in its front paws. It can even eat poisonous plants that are inedible to other animals, mainly from the dogbane family, which contain significant amounts of alkaloids in their bark and sap. The venom obtained during feeding is partially binded and accumulated at the base of the animal’s spikes, from where it is secreted as part of the mucous secretion when the skin is pushed and pressed. The animal smears some of the poisonous sap on its fur and spikes. Due to the porous surface of the spikes, it stays on their surface for a long time and enters the attacker’s body during the spike pinprick. As a result, many predators that have been pricked by rodent spikes get sick or rub the damaged area for a long time, trying to get rid of unpleasant sensations. False porcupine is active at dusk and at night, when the activity of arboreal hyraxes competing with it for food is reduced. During the day, it sleeps in hollows, forks of branches or between the roots of a tree. Sometimes this animal can occupy a suitable burrow, crowding out its owner, but does not conflict with it.
The mating season is not pronounced. Being ready to mate and attracting males, the female puts musk-scented marks. Rivals met each other next to it growl and ruffle their fur, driving each other away from the female. Sometimes such a duel turns into a fight, during which the animals slightly bite each other’s skin, pulling out clumps of hair – but not with full force, because the bite of the incisors of this animal can pierce the predator’s paw to the bone. The female chooses the largest of them, with the deepest voice. As a result of sexual selection, males weigh about one and a half times more than females. The pair stays together for several days, and during this time the male often mates with the female, driving rivals away from her. When the female stops attracting males, the pair breaks up.
After 200 days of pregnancy, the female gives birth to 3 cubs, already covered with hair and soft spikes. Half an hour after birth, their spikes harden and can already partially protect them from predators. Young false porcupines develop rapidly: at 10 days they follow their mother, at 15 they taste adult food, and by the 80th day of life they go without mother’s milk. At 6 months, young animals are already independent, although they stay close to their mother for up to a year. By this time, the female is already pregnant again and soon begins to drive the young away from her, instinctively protecting the territory around its lair. Each female gives birth to 2 broods in 3 years. False porcupines are sexually mature at the age of two years, but males take part in reproduction since the age of 3 years. Life expectancy is about 15 years, although most animals rarely overcome the 10-year boundary due to the grinding of molars. This is especially often observed in animals living in dry forests on the edge of the forest zone, where they are forced to eat highly abrasive food. Natural enemies are owls, which rend the animal’s skin with their claws, and snakes, which are insensitive to poisons dangerous to mammals.

Plains Hopping Mouse (Neonotomys agilis)
Order: Rodents (Rodentia)
Family: Mice (Muridae)

Habitat: Meganesia, tropical scrubland and savannah which extends in the centre and west of the continent.
Success of rodents in the age of man, and subsequently in the Neocene, is undeniable. It was only in the late Tertiary that rodents finally reached the bastion of Australia from Asia, and much later further kinds were introduced by man in the modern age. The original kinds of Australian rodent have proved viable even against introduced kinds, in the Neocene, with specialized forms prevailing in some places.
In the open country of the tropical savannah, lives the Plains Hopping Mouse, a successful descendant of the current hopping mouse (Notomys). Specialized towards an agile, hopping and jumping gait, this adaptation is even stronger in this new form, than its ancestor. The hopping mouse is slightly larger than its predecessor, being up to 5 inches long from head to rump, and weighing up to 40 grams, the tail consists of an additional 5 to 6 inches. Its hind legs and upper part of the foot are long, and the creature usually stands on the tips of its toes, except when at rest. Forelimbs are short and dexterous to aid in feeding; the tail is long and held against the ground, with a tuft of fur at the end. Coat of fur is a pale fawn grey on top, and a whitish cream underneath, the brush of the tail is darker. The face is rather similar to its ancestor, but the ears have become larger in order to aid in dissipating heat, hearing is very acute. This animal’s diet consists almost solely of the seeds of grasses and herbs, but soft tips of new grass growth are also eaten. This rodent is completely nocturnal, sleeping in a burrow throughout the heat of the day.
These animals live generally in small family groups that share a burrow, which is usually dug concealed under a tussock of grass or small hummock of soil. Predators include birds like hawks and owls, as well as Dasyurid marsupials like the marsupial hermin. Breeding takes place frequently and at any time of year, but spring is preferred, pregnancy lasts about 40 days, litters consist of up to 7 babies, which take up to 2.5 months to reach sexual maturity. Lifespan is up to 3 and a half years.
A close relative is the Desert Hopping Mouse (Neonotomys albipes), which inhabits the arid deserts that exist in the far west of the continent of Meganesia. The animal is in general much paler than its relative, being a sandy cream colour above, with white feet and underparts and a ginger coloured tail tuft. It is also slightly smaller, with proportionately larger ears, which are naked on the inner edge, to dissipate heat. Habits and feeding are generally similar, consisting of the seeds of many kinds of sparse desert grasses and sedges, but by necessity they eat the fleshy parts of plants for water more regularly. Breeding is slightly different, being regular but most often coinciding with wet periods and flushes of growth.

This species of mammals was discovered by Timothy Donald Morris, Adelaide, Australia.

Murray Shell Rat (Durohydromys aquatica)
Order: Rodents (Rodentia)
Family: Mice (Muridae)

Habitat: Found in the Murray River of southeastern Meganesia, depths of water, water margins, swamps.
The rodents native to Australia stood fairly well against introduced ubiquitous rats and mice brought by humans. Specialized forms existed, and continue to exist in the Neocene.
Murray Shell Rat is a descendant of the Water Rat or Rakali (Hydromys). Animal is similar in size to its ancestor, reaching 12 inches in length, and up to a kilogram in weight, with females being smaller than males. Outwardly it looks similar to its ancestor, original partway in appearance between otter and rat, with long tail and broad webbed hind feet, fur is velvety and repellent to water. Color is a general chocolate colour above, with a yellowish buff belly, the tail is tipped with white. It differs from its ancestor in blockier robust head bearing even bigger incisors, with a projecting face and profuse whiskers. This is related to diet, which is predominately freshwater molluscs such as snails and bivalves, as well as crayfish, shrimp and occasionally small fish. Hard shelled prey are broken open by gnawing the outside until a large enough hole exists to pry the shell further open. Individuals may habitually make middens in the place where they prefer to consume their food, usually just outside their nest.
This rodent is most active in early morning and late afternoon, individuals are very territorial, fighting over space when they meet each other. Moulting occurs in summer and autumn during the warmer weather. Breeding depends on seasonal abundance of food, and the male will usually find a female with which he may sire more than one litter if the young die, or if it is a good season. This rodent constructs burrows in riverbanks, making a nest of reeds and grass in which to raise the babies. Females are sexually mature at one year, mating occurs from August to October, gestation is 30 days. Females have 4 nipples on the belly and usually produce four young per litter. They are solitary outside the breeding season, and are generally aggressive towards the opposite sex. Any one area will contain multiple individuals that compete and antagonize each other based on age and sex. Young reach full size within a year. Lifespan is short, 3 to 4 years, and they are commonly preyed upon by raptorial birds and occasionally large fish.

Bamboo flute rat (Rattus tibicenis)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: Philippine archipelago, bamboo forests.
The changes in the Earth’s nature at the turn of Holocene and Neocene proved to be a serious challenge for the rich fauna of the Philippine Islands. The depletion of fauna associated with the destruction of tropical forests led to a weakening of competition between species that survived in such conditions, and the subsequent restoration of forests allowed the descendants of these species to evolve in new directions, often changing their way of life drastically. These species include the bamboo flute rat, a specific rat species descended from the Philippine forest rat (Rattus everetti), which was widespread in the Philippines during the human era.
This rodent has mastered life in bamboo thickets, arranging its shelters inside sturdy bamboo trunks. An adult of this species is only the size of a large mouse: the body is only about two centimeters thick, up to 7-9 cm long, and another 5 cm falls on the tail. Females are slightly smaller than males. The body is slender, and the fur is short and velvety. The back, tail, top of the neck and head are colored gray-green, the belly and chest are yellowish-white, sometimes completely white in females. The auricles are small and tightly pressed against the head. There is a certain specialization in the structure of the tail of this species: it is strongly thickened at the base (about one centimeter thick), controlled by well-developed muscles and very mobile. Along its lower edge, there is a callused skin thickening along its entire length, covered with transverse rows of short and stiff bristles. Such a device allows the tail to be used for support inside the tubular trunks of bamboo. By bending it and twisting it into various loops, the animal uses it to fix itself inside the internodes of the bamboo stem, gnawing through the core and partitions at the nodes of the stem.
This animal lives inside bamboo trunks, gradually climbing up the trunk. Periodically, as the upper internodes are lived-in, this rat gnaws holes in the walls of the trunk for ventilation and waste disposal. Because of these holes, bamboo trunks produce whistling melodious sounds in the wind, due to which the rodents got their specific name. Gnawing through the nodes between the plant’s internodes is particularly difficult for a small rodent. It usually takes six to nine hours for a rodent to gnaw through the thickest node. Bamboo flute rat feeds on bamboo leaves and invertebrates, which take shelter at night in the hollow trunks of the plant, including crawling there through holes chewed by the flute rat.
Eventually, after reaching the upper part of the trunk, when the inner cavity is already too narrow even for such a small animal, this rat bites a large hole outwards and begins to build a spherical nest around it using bamboo leaves and fibers. Only males do this. When it is ready, near each hole in the trunk, they begin to spray the odorous secret of the subcaudal glands, the smell of which is carried by the wind, attracting females. These are usually young females who have only recently reached puberty. The male pays attention to the female he likes and lets her into his nest. If the female doesn’t like the nest, she rebuilds it. Bamboo flute rats are monogamous, and a breeding pair usually lives their entire lives in the same nest.
When the offspring appear, the female feeds the cubs with milk, and the male brings food in cheek pouches. A month later, the brood is already able to eat food (which is brought already by both parents), and after another month, the grown up males are expelled from the nest and search for a suitable territory for themselves. Grown-up females leave a little later, in search of their mates. There are up to four litters per year.
Usually, the territory of one family consists of all plants within a radius of 5-6 meters around the nest trunk. The life span of a bamboo flute rat is up to two years.

Noronha rat (Rattus noronhensis)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: Archipelago of Fernando de Noronha.
While humans purposefully introduced some species in new habitats, others were inadvertently introduced. The black rat (Rattus rattus) followed the humans to several places, benefiting from their presence. When they were extinct, some of these rodents were able to survive and continue their evolution. In the Archipelago of Fernando de Noronha, the populations of the black rat that survived evolved into an endemic species, the Noronha rat.
The Noronha rat has 12 cm of body length, with a tail of 9 cm. They have strong forelimbs that are used to excavate the ground to make tunnels to be used as their dens. It has light brown fur with a white underside.
This species is an omnivore and eats a wide range of foods, including seeds, fruit, stems, leaves, fungi, and a variety of invertebrates. Some individuals will also occasionally eat eggs and newborn chicks of seabirds that are left unprotected. However, they need to be careful when approaching the colonies. The adults that nidify in the Archipelago had learned the danger of the rodents, being aggressive with them. The large species of bird can even consider them as a good snack.
Differently from their ancestor, the Noronha rat is monogamous and highly territorial. The limited resources left in the Archipelago after the disappearance of the humans forced these rodents to fight against each other for what they could find. This way, only the mated pair forage together and they defend their dens fiercely against intruders.
Their greatest predator is the gatito, which is capable to invade their dens and to kill them while inside it. However, these rodents don’t fall without a fight. Their fights against the feline could be considered titanic for animals of such small proportion, but even then the gatito ends winning most of the time.
The Noronha rat can breed throughout the year if conditions are suitable, with a female producing up to five litters a year. The gestation period is only 21 days, and litters are formed by 7 to 14. The competition among the young is fierce, with weak siblings of large litters perishing due to it. In these cases, the parents will eat the dead. They reach sexual maturity in about five weeks, which is when they are expelled from the den by their parents. When there is enough food, the female becomes fertile again three weeks after giving birth.
The maximum life span is three years, although most barely manage to one. Unlike their ancestors, they aren’t an invasive species in the Archipelago anymore. The local fauna have evolved together with them and know that they can be a good food source. Beyond the gatito, local herons will also exploit them as such.

Hawaiian bamboo rat (Bambusiphagomys tector)
Order: Rodents (Rodentia)
Family: Murines (Muridae)

Picture by Alexander Smyslov

Habitat: bamboo woods of east slopes of mountains on Big Island (Hawaii).
In human epoch birds dwelt on Hawaiian Islands were a fine example of adaptive radiation - the phenomena at which from one ancestor many descendants evolve. They are connected by relationship, but adapted to different inhabitancies and having various shape. But indigenous species of Hawaiian fauna have irrevocably died out, not having sustained a competition with newcomer species introduced by people. And newcomers, in turn, roughly began to evolve, showing on the example of the same evolutionary phenomenon.
Three species of rats have got to Hawaii on human fault: black (Rattus rattus), brown (R. norvegicus) and indigenous Pacific rat (R. exulans). The third species was quickly superseded by descendants of larger neighbours, and had died out till several subsequent thousand years. But two remained species had actively evolved, having given many various descendants distinguished by appearance, behavior and habit of life. Descendants of brown rats became mainly ground animals, and black rat – wood inhabitants.
A few species of mammals live in bamboo woods. In this place it is difficult to move quickly - trunks of bamboo form almost solid walls, and between them the large animal simply cannot walk through. But smaller species of rodents, adapted to existence in this original biotope, prosper. At first it is difficult to find out about presence of these small mammals in dense bamboo wood, but gradually these animals find themselves out. They run on wood litter, rearing from time to time among trunks, and showing improbable, practically squirrel-like speed, climb up on smooth and firm stalks of this graminoid where even for cat it would be difficult to seize against something. It is the Hawaiian bamboo rat, the descendant of black rat (Rattus rattus).
Hawaiian bamboo rats are small rodents, like only the young grey rat by size. They have kept the appearance typical for representatives of family, but have got some features, permitting to survive in specific biotope. Representatives of this genus of rodents meet exclusively in bamboo thickets, and are not found anywhere more. On each island of archipelago there is the species of these rats distinguished from others in size and features of coloring.
The Hawaiian bamboo rat dexterously swarms up stalks of bamboo. It has tenacious claws, but it is not enough to it to show such quickness like it swarms up trunks of bamboo. On palms and feet of rodent the skin forms small holes acting like suckers. With their help rat can quickly run on smooth trunks of bamboo. To improve action of suckers, sudoriferous glands on their edges are hypertrophied, and allocate stickier secret providing the best sticking to trunk.
The short wool of the rat is colored yellowish – brown. On back of rodent there are dark longitudinal stripes – they mask this animal in the world of vertical trunks of bamboo. The amount of strips and their pattern considerably vary at different individuals.
Hawaiian bamboo rat completely depends mainly on large species of bamboo with thick trunks. Such choice of habitat is connected with the fact that all species of Hawaiian bamboo rats arrange shelters, simply gnawing out apertures in ripen hollow trunks of bamboo. After rats birds use their tree-trunk hollow: on Hawaii there are no woodpeckers, and, except for rodents, there is nobody able to make tree-trunk hollows here. And the natural tree-trunk hollows formed in trunks of some trees, does not suffice for all. Therefore some birds depend on well-being of bamboo rats.
This rodent has one more important “duty”: because these rats eat young sprouts of bamboo, they thin out thickets of this graminoid in such way. To gnaw hollows and to chew firm stalks of bamboo, at this rodent large incisors and short strong jaws were developed. Cheekbones of this rodent are wide, and jaw muscles are very strong.
All bamboo rats are solitary animals preserving the territory from neighbours. Only during breeding season males can come in territory of females for pairing. Usually per one year at the female it happens three litters of 5 - 6 cubs. They are born naked and blind, but develop rather quickly. Bi-monthly animals leave mother, and search to themselves for suitable place for life. Usually in territory of each adult animal it happens some shelters gnawed in trunks of bamboo, and young animals frequently lodge in them, choosing ones in which the lawful owner of territory was not for a long time.
Trunks of bamboo are very strong, and animals settling in them are perfectly protected from many enemies. But occasionally the population of Hawaiian bamboo rats has not best times. During flowering of bamboo (one - two times per one century) number of Hawaiian bamboo rats is considerably reduced: the bamboo dies off after flowering simultaneously in big territories, and rats sometimes appear without food among a congestion of died out trunks of these graminoids. The survived rats in small amount pass to other forage, eating young sprouts of bamboo, slowing down naturally its distribution. Also at lack of the basic forage they eat fleshy rhizomes and the bottom part of stalks of other grasses, including other species of bamboo.
On other islands of the Hawaiian archipelago close species of bamboo rats live:

Black-backed bamboo rat (Bambusiphagomys melanodorsus) lives on Molokai Island. It is the small species representing by the size something mean between rat and mouse. This rodent lives on medium-sized species of bamboo and at tops of large species, choosing the internode of suitable size. The basic colouring of its wool is sandy – yellow, and on back from a nape up to the basis of tail one wide black strip stretches. Occasionally on sides there are pale longitudinal strokes.

Picture by Alexander Smyslov

Narrow-striped bamboo rat (B. angustizonus) is also small species meeting on Maui Island in thickets of small-leafed species of bamboo. It arranges shelter in the basis of trunks in the thickest internodes, but feeds mainly at tops of bamboo, eating insects and young leaves of this grass. On its back set of narrow longitudinal stripes of brown color stretches on grayish - white background; stomach is white.

Picture by Alexander Smyslov

Half-striped bamboo rat (B. hemifasciatus) lives on Lanai Island. This rat differs from close species in remarkable colouring: on forward part of body strips are absent; they begin only on middle of back, and cover waist and hips of animal. The basic colouring of this animal is light grey with black strips. On head and cheeks of this rat there are white spots using for recognition of congeners. Except for colouring, this species differs in more graceful addition: lengthened body, short forepaws, narrow muzzle and long tail. This rat reaches usual length of grey rat, but weighs approximately twice less than it.

Hawaiian gatherer rat (Pacifirattus collector)
Order: Rodents (Rodentia)
Family: Murines (Muridae)

Habitat: Hawaiian Islands, rain tropical woods.
Hawaiian islands differ from set of other islands in rather big area and huge variety of possible habitats given to live creatures. The complex mountain relief creates a plenty of rather isolated habitats and as the consequence of it, set of various though also closely related species of small live creatures lives on Hawaii. They differ from each other in features of appearance, way of life and behavior. Such variety gets sometimes the extremely fantastical forms.
Mammal of Hawaiian Islands evolved mainly from animals introduced by people. And rodents reached the greatest variety among them. Having high speed of alternation of generations and small size, they could occupy various ecological niches. Island descendants of rats differ from each other in size, way of life and features of behavior.
In human epoch in territory of Australia and New Guinea bower birds, and in pampas of South America large rodents viscachas lived. These animals had differed in one interesting feature of behavior: having predilection for various bright objects, they collected them, arranging in special places original “exhibitions”. The similar creature lives on Hawaii in Neocene epoch. It arranges round wicker drays in branches of bushes, and places “collections” of shining exoskeletons of beetles and snail shells around of them on broken off knots. Owners of building, the breeding couple, from time to time flash in foliage, hastening to the dray or back.
This four-pawed “collector” is Hawaiian gatherer rat, a creature like large grey rat (Rattus norvegicus) by size, and by the way it is its strict descendant. This rodent leads semi-climbing habit of life, swarms up bushes well, and arranges drays at small height from the ground. For protection against enemies this rat builds drays in prickly bushes.
Being a day time animal, Hawaiian gatherer rat has the bright colouring appreciably distinguished from monotonous and dim colouring of ancestor. At this rat there are red back with longitudinal lines of dark speckles, brown head and white spots near black ears. Also there are white points above eyes. At this rat there are large eyes and wide rounded ears through which there leaves surplus of heat in hot day. Paws are armed with sharp tenacious claws; joints are very mobile, hand and foot can turn aside to the significant corner.
This rat is omnivorous, but prefers food of animal origin. It eats various snails including predatory ones, at an opportunity ravages nests of birds and eats insects. Frequently this rat eats large beetles, and drags their shells to the dray to supplement its “collection”. This rodent lives at edges and damaged sites of wood where bushes plentifully grow. It is able to swarm up branches perfectly, and here prehensile tail making more of half of the general length of rodent helps the rodent. The tail is naked, covered with grey skin with separate bristles. It is used as the balance weight more often. Jumping from branch to another, this rat can drive by tail, or rotates it to turn over in air and to land on paws like the cat. On the bottom side of tail the cross horn combs permitting to catch for bark stronger when rat moves in bush, are advanced.
Dray of this rodent is similar to squirrel’s one: it is spherical, wattled of rods, arranged in densest part of bush thickets. Similar drays martenrats from Tonga islands plait independently of them, but at the Hawaiian rats, as against to Tonga ones, the entrance to dray in turned not from below, but sideways. This rat frequently alters for habitation bird's nests, preliminary having attacked on owners and having ravaged their clutch. Drays made among prickly bushes are especially appreciated. This species lodges in drays in pairs kept for some seasons, and frequently till all life. For strengthening of relations between partners rats use various symbolical “gifts”, and by their amount near the dray it is possible to judge force of matrimonial connections: the strong pair in the prime of life collects many various “gifts”, and successfully protects them from encroachments on the part of congeners. Usually these rodents collect bright snail shells under “butcheries” of local hookbill bird eating snails, and decorate with them an entrance to the shelter. For the organization of “exhibition” pair of rats gnaws off a part of branches near to bush in which the dray is arranged, clears them of foliage and bark, and picks on them shells, dead beetles of bright coloring and if their number is too little – live flowers. The single male, having won itself a bush suitable for habitation, first of all organizes “exhibition”, and arranges dray only later. The more bright and large will be such collection of bright objects, the more obviously force and dexterity of animal had collected and had kept it. Different pairs have different predilections - near some drays there is more live flowers, near others shells or elytrums of beetles are presented. Pairs at gatherer rats are to no small degree formed on generality of “aesthetic views” of partners. The “exhibition” is regularly updated: the withered flowers and dried berries are replaced by fresh ones, and new “exhibits” found, or stolen at neighbours from time to time are added there.
During courtship displays the male drags in teeth bright objects from “collection”, showing them to female. It serves as original “substitute” of secondary sexual attributes. Partners from amicable pair in common steal ornaments at neighbours and protect “collections” from ravaging. If necessary these rodents can drive off from bushes even local huge herbivore birds (giant forest geese), frightening them by shrill squeal. If birds do not recede, rodents even attack them, biting birds in unprotected paws. Some pairs of these rodents can operate in common against the large enemy.
Seasonal prevalence in breeding of the Hawaiian gatherer rats is not present. At any time year in drays of these rodents it is possible to find cubs of various ages. In litter of this rodent three - four times per one year up to eight - eleven naked blind cubs appear. The female cares after them, leaving posterity only for feeding, and the male is completely occupied with protection of fodder territory and “collection” from neighbours. At week age the young growth becomes covered by wool, for the twelfth day starts to see and hear. Up to monthly age rat cubs stay in dray, and later start to play already outside of home: swarm up branches, drag small objects, trying to steal them at each other. Bi-monthly cubs already receive punishment from parents, and one by one abandon parental territory. In youth, not having an own home, they are very vulnerable, and at this time perish from various predators. Up to half-year age, when the young animal becomes strong enough to win to itself territory, only few individuals survive. Life expectancy of these rodents is short – only few animals live till three years, and the majority does not live even till two years.

Mangrove builder rat (Architectorattus piscatorius)
Order: Rodents (Rodentia)
Family: Murines (Muridae)

Habitat: Meganesia, mangrove forests of Arafura Lake.

Picture by Sauron

Rodents were only terrestrial placental mammals in Australia before the human arrival to this continent. Under human influence the fauna of Australia had substantially lost the originality, and a plenty of non-native species introduced from other continents had appeared in it. During the time pased from the moment of extinction of mankind, some lines of placentals had declined, and others, on the contrary, continued the prospering. Rodents are especially succeeding group among them. The type of anatomy, characteristic for rats and mice, appeared very successful, and numerous rats had settled in various biotops of Meganesia. One of their species due to versatility of behaviour had developed mangrove forests separating by thousand-kilometre wide barrier Arafura Lake from the ocean. It is very specific environment where small islets of land alternate with impassable marshes and rich mattings of roots and branches of mangrove trees.
The large species of rats well adapted to life in such inhabitancy lives in branches of mangrove trees. Its settlements represent “towns” of several tens of nests looking like small huts arranged on branches. Because of this feature the animal is named mangrove builder rat.
This mammal is medium-sized aquatic rodent: its body length is about 30 cm. It has anatomy typical for rats, long flattened muzzle and short forepaws with mobile fingers and sharp claws. Rear legs are big and strong, and have membranes between toes. Auricles are small. When rat dives, acoustic duct is closed by the special skin valve. Mangrove builder rat has long tail, which serves as a counterbalance when it swarms up branches. Wool of animal is velvety and rich, but short. This rat greases it with fat secretions of special glands, and spends a lot of time cleaning it. Cleaning of wool at these animals is a mark of mutual attachment, and the individuals standing below at the scale of rank express submission to stronger individual this way. The top part of body of mangrove biulder rat is colored beige; throat and breast are white.
This rat eats fish, crabs and insects, and also consumes fruits and young leaves of mangrove trees. It is able to swim and dive well, and during the inflow it hunts for fish and other water animals. Swimming under water this rodent presses forepaws to breast and rows by hinder legs. Mangrove builder rat leads social habit of life and settles among mangrove thickets in colonies numbering some tens of individuals. The inhabiting in holes and hollows traditional for rats does not fit to conditions of mangrove forest – ground is regularly flooded here, and hollows in tree trunks are not so extensive to contain the numerous colonies of animals. Therefore during the evolution at these rats the special form of building behaviour had developed. Each breeding pair constructs for itself the original dwelling – primitive conic-shaped “tent” which is located above a level of the highest inflow. By this feature mangrove builder rat is similar to martenrat from Tonga Islands – the rodent developed during the evolution process the similar kind of shelters independently of it. In the basis of “tent” there is a small wum platform made by animals of fibrous leaves of palm tree and pandanus, or of bark of mangrove tree sprouts. Above it the dome of arched bent rods is erected, on which the roof made of leaves is attached. The ready construction has conic shape. Houses of mangrove builder rats form a kind of “village” where up to ten pairs of adult animals and numerous young ones live. At the exhaustion of fodder resources the colony abandons “village” and moves to new places where new constructions are quickly made.
Within one year the pair of adult rats may bring into the world up to four litters of 6 – 8 cubs. They develop quickly and already at the age of 6 – 7 weeks become independent and make their own constructions at the edge of “village”. At the age of half-year they become sexually mature. Life expectancy at these animals does not exceed three years.

Kapo (Kapo hawaiiensis)
Order: Rodents (Rodentia)
Family: Mice and Rats (Muridae)

Habitat: Hawaii Islands, Big Island.

Picture by Alexander Smyslov

Before the people arriving to Hawaii mammals of this archipelago were presented only by bats and seals. In common with people new animals appeared at the islands, and among them there was a rat – one of the first ground mammals appeared in Hawaii. Their occurrence has resulted in disappearance of significant number of bird species existed at Hawaiian archipelago. Despite of human efforts directed to extermination of these animals, rats have not died out on Hawaii, and managed go easily through the period of global ecological crisis. After stabilization of climate various species of rats differing from each other in ecology and way of life had evolved on Hawaii. The largest descendant of introduced rats is kapo, animal similar to South American rodents agouti and paca, known in human epoch.
Kapo is very large species of rodents: the adult animal weighs about 5 kgs at body length about 40 cm. In its constitution kapo resembles a pig – this animal has short and muscled body, large head with narrow mobile muzzle and long whiskers, rather long legs and short thin tail. Colouring of this animal helps this rodent to hide in vegetation of underbrush: primary colour of kapo wool is grey, along back some faltering black strips stretch, and the top part of head is black. This rodent has rather large eyes. Above kapo’s eyes there are two big white spots helping this animal to distinguish congeners. Auricles of kapo are large, rounded and rather wide – they serve for body cooling in hot climate. From the outside edges of kapo’s auricles are covered with white wool that permits the animals to notice each other in shady underbrush. This species of rodents is almost exclusively vegetarian though it does not miss an opportunity to catch large insect, crab or snail. Its basic food includes seeds, roots of grassy plants and green. Kapo moves on ground on straightened legs. It can run very quickly, suddenly changing direction of run for protection against enemies. This animal is heavy enough, and it is not able to climb on trees. If the animal can not escape from the enemy, it protects itself, putting deep lacerations by incisors.
Kapo is especially active in twilight and in early morning, and prefers to hide in various shelters in the afternoon. In middle of night kapo also has a rest within several hours. These animals dig short holes with a characteristic bend: the beginning of hole is almost horizontal, then it makes a sharp bend downwards, and proceeds horizontally or slightly inclined upwards. It is very difficult to dig out such hole, and it serves as good shelter for animal. Kapos make “stores” of seeds in forest, digging under roots of trees small holes and filling them with gathered seeds. They especially frequently reserve large seeds of palm trees and leguminous plants. The part of stocks will be eaten, but not completely – kapos frequently do not pull out all seeds from “store”, or forget the stock at all if find enough food. And then through any time in forest whole bunches of sprouts of various plants appear. Similarly to South American rodents, Hawaiian kapos carry seeds of palms and other trees with large and heavy seeds. Hence there is their name: Kapo is a god of fertility at ancient Hawaiians.
Kapos live in pairs or in small groups: pair of adult animals and their posterity. Each pair has the certain territory where the shelter is arranged, but is fed in the distance from it. Inhabited holes of kapo are made nearby one from another, and individuals of different pairs communicate with each other with the help of sounds and movements of body. The pair is formed for some years, and brings posterity two times per one year. In litter at kapo there are about five naked blind cubs. Within two months of life they acquire wool, grow considerably and become more mobile. At them eyes open, they start to get out of a hole and to learn world around. In the beginning of the third month of life young kapos start to lead the same way of life as adult individuals, and completely pass to food of adult animals. At the age of 20 months young animals reach the size of adults and can give posterity. Life expectancy of kapo rarely exceeds five years.

Poison-toothed giant rat (Cobrodus toxicodus)
Order: Rodents (Rodentia)
Family: Mice and Rats (Muridae)

Habitat: Southeast Asia, tropical forests, the sites overgrown with grassy vegetation.

Picture by Alexey Tatarinov

In tropical forests of Neocene epoch rodents represent one of the most typical groups of mammals. These animals have great range of habitats – from underbrush up to forest canopy – and occupy various ecological niches. Due to ecological plasticity rodents had successfully gone through the time of anthropogenous pressure and had reached blossoming in Neocene epoch. Their adaptations for survival are very diverse, and some Neocene species have developed adaptations unknown in human epoch.
The massive sluggish rodents similar a little to badgers with long hairless nonflexible tails live in forests of Southeast Asia. They are large descendants of any from numerous species of rats (Rattus); the body length of adult individual reaches 50 – 60 cm (and tail is about 40 cm long), and weight is up to 7 – 8 kg. They live in family couples and constantly search for food together. The body of these rodents is covered with rigid wool of rusty-brown color, lighter on stomach. Head is colored very brightly and sharply contrasts with body colouring: on white background longitudinal black strips stretch – some narrow strips on forehead and one wide stroke on each cheek. Such colouring is very well perceived by predators lack of color vision, and is remembered by them for a long time after acquaintance to protective adaptations of these rodents. The bite of these rodents is poisonous.
Poisonous mammals are known in human epoch – they are monotremes and some insectivores. They secreted their own poison from special glands: duck-bill from spurs on legs, and shrews from modified salivary glands. Poisonous shrew lives in Neocene in forests of Europe. Poison-toothed giant rat differs from them in origin of poison: in modified salivary glands of this rodent the poisons received from plants are accumulated. At an attack of predator poison-toothed giant rat first of all displays to the enemy readiness to protect itself, widely opening mouth and bristling wool on head. If the enemy continues attempts of attack, the rodent counterattacks it and bites strongly. On top incisors of poison-toothed giant rat from external edge there is a groove which gradually goes deeper when animal is older and turns to closed channel. The duct of specialized salivary gland opens in it. Obviously, at ancestors of these rats salivary glands began initially to filter and to excrete a part of alcaloids received with food, which has allowed rodents to eat poisonous plants, avoiding a competition to other herbivores. Then additional function gradually turned to basic one, and salivary glands had turned to stores of poison.
The diet of these rodents includes a significant part of poisonous plants of various families, usually spurges and sumach. When poison-toothed giant rat chews poisonous plants, poison from their sap is intensively absorbing by mucous membranes of mouth and is immediately filtered in salivary glands. This species has very expressed immunity to plant poisons, and also to poisons of snakes and numerous invertebrates. Due to such diet poison-toothed giant rat avoids food competition to other species of animals.
Voice of this rodent represents silent sounds similar to pig grunting and puffing. Alarm call of poison-toothed giant rats is shrill whistle heard from very long distance. Using it, these rodents warn each other of occurrence of predator. Protecting itself from the enemy, poison-toothed giant rat displays to it contrast colouring of head and utters loud squeal. If the predator does not stop an attack, poison-toothed giant rat puts to it deep snaps and injects poison in wounds at these moments.
These animals live in pairs in large holes arranged under roots of big trees. The pair at poison-toothed giant rats is kept during very long time – partners may raise posterity in common within several years in succession. Within one year this rat gives birth to two litters numbering 2 – 4 cubs. They are born blind, but covered with rare wool. Female looks after them within one month while cubs will develop enough to search for food independently and to follow parents.
The first months of life poison-toothed giant rat lacks characteristic poisonous bite, because it has weak immunity to poisons, and eats nonpoisonous parts of plants. At this time only protection of this animal is its own care. Young animal gradually includes poisonous plants in diet, and later becomes capable to accumulate poison in salivary glands.

Singing gliding rat (Aerorattus cantans)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: Philippine Archipelago, tropical forests.

Picture by FanboyPhilosopher

The global cataclysms that occurred at the end of Holocene and the beginning of Neocene swept into oblivion many species and families of animals known in historical times. The survived species began to explore new ecological niches, and the most unpretentious, persistent, and poorly specialized species succeeded in it. Rats were one of the groups of animals with such set of qualities. In the Philippine Archipelago, one of the most successful species of the post-human era was the widespread Philippine forest rat (Rattus everetti). Its descendants have replaced many species that have either disappeared or lost ground, unable to withstand the competition. Some of the evolutionary lines followed by the descendants of this species were quickly suppressed as a result of competition with other animal groups, but some specialized species live in the forests of the archipelago in Neocene, which are the fruits of evolutionary experiments of Early Neocene. One of them is the singing gliding rat, which partly took the place of the extinct colugos.
It is a creature with a body length of about 20-25 cm, not counting the tail. Despite its rather large size, this rodent has a light build and can make gliding jumps from one tree to another. The patagium connecting the neck, the bases of the hands and feet, and the base of the tail helps the gliding rat to keep in the air; gliding from one tree to another, the animal looks like a small kite. The animal has a relatively long tail (15-17 cm long) with a tuft at the tip, which helps it when performing maneuvers in the air. The creature has a light brown back with dark specks, and a lighter belly. The animal snuggled against the bark is hard to notice due to its camouflage coloration. There is a throat sac with extensible walls on the neck, which is an outgrowth of the trachea; in females it is covered with pale yellow hair, and in males it is saffron-red. The animal’s muzzle retains a typically rat-like appearance, the ears are slightly smaller, and the snout is slightly longer and thinner than that of an ordinary rat. The eyes are relatively large; they are directed not only to the sides, but also forward, providing partial binocular vision. The paws of this arboreal animal are armed with long tenacious digits with hooked claws, and the toes are longer than fingers. The animal feels very confident on the trunks and branches of trees, and is very reluctant to descend to the ground, where its long fingers and toes only discommode. But these rats deftly climb thin branches and glide between trees.
The animal’s food consists of fruits, bird eggs and invertebrates. Gliding rats are diurnal and live in large colonies, which number up to a couple hundred individuals.
The animal’s throat sac is used for communication – these rats utter melodious trills, very similar to the song of birds (hence the name); males also use it for mating displays. The sounds made by these animals are very diverse: these are trills of various frequencies and single calls. Animals have a tendency to imitate sounds, and in their own way they adopt and reproduce the sounds of birds and insects living in the neighborhood.
Migrations of gliding rats look very impressive, when chirping colonies of hundreds of animals move in the upper part of the forest canopy, covering the distance between the trees in one gliding jump. At this time, there are several dozen animals in the air at the same time. Another use of the throat sac is as a shock absorber when it is inflated, when animal is landing on a tree, and can cushion a failed landing. The long prehensile tail is used as a rudder during the gliding jump, but the animal also uses it as a safety rope during feeding – the rodent hangs on it upside down, clinging with its tail to the tip of a thin branch. At night, these rodents hide in tree hollows and in nests woven from branches. Owls belong to the most dangerous enemies of this species.
The mating season usually happens every four months, but the biological cycles of different individuals do not coincide, and there are always females in the colony ready to reproduce. Males often arrange duels near ready-to-mate females: they measure their throat sacs and push with them, figuring out their right to mate first. Usually, several males manage to mate with a female, but only one of them fertilizes her. After two months, one or two cubs are born. But low fertility is compensated by the degree of development of the cubs: they are covered with hair and are able to cling immediately to their mother’s skin. They spend the first time firmly holding to the mother’s back, although sometimes the cubs break off and die during gliding jumps. The high degree of development of the cubs allowed these rats to abandon the establishment of permanent nests, and their colonies can move to new places rich in food more easily. At the age of 30 days, young animals begin to lead an independent life, and the female is ready to mate again after a short period of recovery. The cubs reach maturity after six months. The life span of singing gliding rats is from five to seven years.

Narrow-faced rat, kiwi rat (Stenorattus aodon)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: Indonesia, Jakarta Coast.

Picture by Alexander Smyslov

In Neocene epoch, rodents are still the most diverse group of mammals. In the process of evolution, a large number of specialized forms have appeared among them, which have mastered a specific lifestyle or diet. One of the peculiar rodents of Neocene is the narrow-faced rat, which lives in the rainforests of Southeast Asia. In its appearance and behavior, this rodent is a kind of analogue of African sengis. The narrow-faced rat has a very long and narrow muzzle: the length of the animal’s head is equal to the length of the body (excluding the tail). The length of the animal’s head and body is about 30 cm, and the length of the tail is about 25 cm. The animal’s muzzle is very long: about two thirds of the total length of the head. A significant part of it consists of narrow and long incisors, which are elongated forward. When the mouth is closed, the incisors of the beast touch each other, forming a kind of tweezers. The other teeth are greatly reduced – in each half of the jaw there is only one cutting molar with a blade-like crown. The soft tissues of the head form a kind of “case” for tweezer teeth. The animal’s nose is very mobile; it looks like a proboscis with a cartilaginous “pig snout” at the tip. Lower lip has a movable sensitive tip. The animal’s mouth can open wide.
The narrow-faced rat has wide mobile ears that can turn in any direction, long whiskers, and large eyes. By lifestyle, it is a nocturnal animal, which prefers to hide in a hole during the day. It is a solitary animal species that thoroughly marks its territory with urine. In case of penetration of a stranger into the territory, narrow-faced rat drives it away, uttering a loud squeal. If this does not help, the owner of the territory “pecks” the opponent with its incisors, only sticking their tips out of its mouth, but not opening its mouth. In case of danger, the animal, on the contrary, clings to the predator’s skin with incisors and inflicts deep wounds.
The wool color of the narrow-faced rat is contrasting: light gray with a black head and a black stripe along the back. The ears are covered with hairless skin, through which blood vessels appear, and the long hairless tail is covered with gray skin.
The hind legs of the animal are slightly longer than the front legs, so when moving, the animal’s butt is raised above the shoulders. At night, the animal runs through the forest in search of food, mincing its paws quickly. In case of danger, this rat flees – it makes long jumps on its hind legs, pressing its front paws to its stomach. At this moment, its tail serves as a balancer. Fleeing from the enemy, this rat is able to make jumps up to one meter in height and abruptly change the direction of movement.
The narrow-faced rat has a very specific diet, which is associated with a peculiar development of teeth. This species feeds almost exclusively on soft-bodied invertebrates – worms, cockroaches and grubs living in the forest floor. Narrow-faced rat searches for them by plunging its snout into the forest floor almost up to its eyes. Hence the second name of this rodent – “kiwi rat”, given for its peculiar manner of feeding. The proboscis of the animal feels the plant remains and detects the smells of animals hiding under them. The rodent extracts them from the wood litter with its tweezers-shaped incisors and kills them with a bite, cutting through their cuticle at the same time. The tongue with a brush of corneous jags on its tip helps to extract soft contents from the cut cuticles of insects.
This species breeds up to 5 times a year. The female gives birth to 5-8 cubs in a deep hole or other safe shelter. At the age of 3 weeks, young rats leave their mother and begin to search for food on their own. They reach sexual maturity at the age of 4 months, and their lifespan rarely exceeds 2 years.

The idea of the existence of this mammal species was expressed by Tim Morris, Adelaide, Australia.

North Island Tree Rat (Neouromys carpophagus)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: Sub-tropical woods and forests of the northern part of North Island, New Zealand.
The brown rat (Rattus norvegicus) has been a constant commensal and pest of mankind, and has spread wherever he went. Stowaway rats that came to New Zealand soon became very successful, and have left descendants in the Neocene.
North Island Tree Rats are very large rats, living mainly in the branches of forest trees, and feeding on fruit and seeds. Physical shape is generally more elongate and less stout than its ancestor, though it is overall heavier. They reach 35 centimetres long, not counting the tail, and can weigh up to 1 kilogram, the tail is longer than the body, and used to balance itself when climbing. Face is fairly long with a “roman nose” shape and large incisors, cheeks are large and can be used to store food. Colour of fur is light greyish brown with darker markings around the face, feet are pink, tail is naked and dark grey.
Diet consists of the fruit, nuts and large seeds of forest trees, individuals make nests out of leaves in the branches where they store food they have gathered, and also where females raise their young. This animal is nocturnal and rather shy; it can flee through the branches into the treetops very quickly. Animals communicate when they meet with various squeaks, some of which are ultrasonic, individuals are mostly solitary but tolerant of other individuals, and any one piece of territory may have up to 20 individuals ranging within it, of which certain bigger individuals will be dominant.
Breeding occurs from September to December, sexual maturity is reached at 9 weeks. Males do not compete to breed, and any female may bear young sired by a number of males, gestation is from 25 to 30 days, and litters consist of up to six babies, which remain with their mother for up to three months. Females groom their young to clean them and secure social bonds. Lifespan is up to 5 years.

This species of mammals was discovered by Timothy Donald Morris, Adelaide, Australia.

Aotearoan Ratmarmot (Marmotarattus australis)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: Open country, meadows, grassland, scrub, grassy mountain slopes, North and South Islands of New Zealand.
The adaptive radiation of Rodents in New Zealand was seeded by stowaways on ships, and has resulted in numerous novel and specialized forms, including those converging upon kinds from other continents, such as marmots.
Ratmarmot is a common inhabitant of open country in New Zealand, pretty much wherever there is grass, and ground which is not swampy. These rodents reach about 30 centimeters in body length and about a kilogram in weight, constitution is more muscular than its ancestor, with strong limbs bearing large digging claws. The tail is relatively short, furred and thick, serving as a store of fat. Fur colour is a overall dark brown, but northern populations are lighter and more greyish, belly is dirty white, feet and nose are blackish.
Diet consists almost entirely of grass and herbage found in open country, as well as seeds occasionally, individuals will graze by day and into twilight, rushing into the safety of communal burrows at the slightest sign of danger.
This animal is highly social, building large underground warrens in which may live many tens of individuals. Warrens consist of a network of tunnels; living chambers, and nursing chambers, dung is thrown out certain exits that serve as latrine piles. Warrens have many entries and exits, some hidden, and sentries stand atop mound-like entrances, on their hind legs, calling with loud strident chirps in case of danger.
In the group, dominant large females breed the most often, suppressing the hormones of subordinate females by harassing them. When a group becomes too large, fighting occurs and generally subordinate individuals are driven out to start new colonies. Individuals groom and play fight to strengthen social bonds among comrades and sexual partners, and females affectionately clean their young.
Breeding occurs from April to July, the male makes a recurring, chirping mating call around an entrance to entice a female, showing his vigour by being exposed. Mating occurs underground, fighting and grooming are an overture to mating. Extra mating is prevented by a “copulatory plug” of semen. Gestation is up to 30 days, litters of babies consist of between 6 and 9 individuals. Babies are nursed by the mother underground for six weeks, after which young start to venture out, and soon begin adult feeding behaviour. Sexual maturity is reached at 12 weeks, and lifespan is up to 5 years.

False-guatusa (Dasyproctomys insularis)
Order: Rodents (Rodentia)
Family: Mice and Rats (Muridae)

Habitat: Galapagos islands, forests of the main large island.
Several species of mammal became invasive with the colonisation of the Galapagos Islands, thankfully some like goats and dogs, were exterminated, but others, like the Brown Rat (Rattus norvegicus) managed to avoid human interference and prosper, leaving diverse descendants in the Neocene.
This large rodent is an ecological analog to the Holocene Agouti (Dasyprocta) of South America, this is where it gains part of its name “guatusa” Ecuadorian word for Agouti. They reach about 40 cm long and 4.7 kilograms on average, being moderately large for a rodent. Coloration is a reddish brown, with numerous pale spots, face and extremities bear darker fur than the rest of the body, nose and soles of feet are bare and pink, ears are large and prominent, hairless. It has a short, muscular body with a large rump; forelegs are shorter than hind-legs. Limbs are rather long, and this animal is able to run fairly fast through the undergrowth to escape predators. Head is blocky and muscular, with large orange incisors, this is connected to its diet, hard seeds which have fallen to the forest floor, other forage includes soft understory growth, fruit, occasionally insects and eggs of nesting birds.
This animal is most active at twilight and early morning, but may also forage by day. Nest of this animal consists of a large scrape in the ground, under a bush or small tree, which is lined with dry leaves. Pseudo-guatusa will bury caches of gathered seeds in certain spots within its territory, but it rarely forgets where they are. Animal is solitary, but will tolerate others of its kind, many individuals may share a common territory. Communications consists of high chirping squeals and clicking of incisors, call when distressed or alarmed is a high long squeal.
Breeding occurs year round, female may bear up to 3 litters a year. Males seek out females by scent, and may confront each other in order to compete for mating rights by posturing and attempting to bite one another. Litters consist of up to 5 pups, which are born naked and blind but mature very quickly. After two months young are fully furred and able to follow their parents and consume adult food, sexual maturity is reached at one and a half years. Lifespan may be up to 5 years but usually much shorter.

This mammal species was discovered by Timothy Donald Morris, Adelaide, Australia.

Common anguja (Anguja robustus)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: coastal forests of southeastern and northeastern South America.
Even with the impacts caused by human interference in the nature during the Holocene, some species are capable to survive and continue with their evolution. In the Neocene, a new genus of rodent appeared, the Genus Anguja, this name means rat in the Guarani language. The members of this Genus are all predatory rodents, acting like the carnivorous marsupial mice of Australia. The type species of this Genus is the common anguja, a species that lives in the coastal forests of southeastern and northeastern South America.
The male common anguja has 14 cm length, while the female has 12 cm. They are greyish brown, with pale grey undersides and feet. The tail is long, bushy, and flattened from base to tip. The ears are larger and rounded. Common anguja are good climbers and have sharp claws. They use their long tails for balance while climbing and jumping.
This rodent is a good hunter, specialized on hunting at night. Their diet consists mostly of insects, centipedes, arachnids and other vertebrates. They will attack nests of birds, eating eggs, chicks and sometimes the parents that are taking care of the young. The common anguja is resistant to the poison of some species of scorpions and spiders.
This rodent inhabits tunnels and pathways created by other rodents. Given their good ability to climb in trees, they can also make dens inside hollowed trees, preferably those that were once used by birds as nests, which eggs they could have eaten.
Common anguja has about two or three litters a year consisting of two to seven young. They have a gestation of 32–47 days, and the young are born in either late fall or early winter in dens dug by the parents. Living in pairs, the male gathers and provides food for the female while she is pregnant and taking care of her young. The common anguja is an altricial species; young rodents are naked with closed eyes when they are born, and weigh about three grams. Both sexes reach their sexual maturity at three months. Their lifespan is of 6 years, but many perish with few weeks and months.
Other members of the genus Anguja:
Striped anguja (Anguja striatus)
This species inhabits the savannas of Northeastern and Central South America. The male has 16 cm of length and the female 13 cm, thus being the largest member of the genus. Their fur is yellowish brown with characteristic dark strips in the back. They attack the communal nests of azure parakeets, sometimes doing their dens there. The striped anguja is the favorite prey of grey-faced pygmy owl during nesting season.
Auburn anguja (Anguja rufus)
This species inhabits the forests of Southern South America. The male has 13 of length and the female 11 cm, thus being the smallest member of the genus. Their fur is reddish brown with pale grey underbelly. They prey mostly on invertebrates, sometimes eating small frogs and lizards.

This mammal species was discovered by João Vitor Coutinho, Brazil.

Marinating Coney Rat (Marinadomys herbosiros)
Order: Rodents (Rodentia)
Family: Mice and Rats (Muridae)

Habitat: North America, temperate zone, meadows, fields and grassland.
North America played host to its own endemic families of rodents during the Holocene, which were later joined by introduced rats and mice of the family Muridae, due to the actions of man. These animals have left descendants in the Neocene.
Marinating Coney Rat is descended from the Brown Rat (Rattus norvegicus), it looks outwardly a little similar to its ancestor, apart from lack of tail and more rounded face, it reaches a length of 30 centimetres and a weight of 550 grams. Coloration is somewhat more distinct, with a white belly and dark fawn-colored body, face is darker and extremities are naked and pink.
Its diet is more specialized than that of its ancestor, feeding mostly on herbs, weeds, grass stems, the leaves of low shrubs, and grass seeds. It usually gathers them in portions and stores them in its nest, which is a relatively deep hole, usually made in lee of a rock or tree stump. Animal remains active through the winter from making large stores of food. What it does with its stored food is extraordinary, it will cache fibrous and tough grasses and herbs alongside large amounts of weeds which have acidic, sour juices and sap. The stored food that it does not immediately eat slowly starts to decompose, and the juices from the weeds proceed to break down some of the structural chemicals within the stored food. To protect it from the air oxygen, this rodent buries the stored feed in the ground. It is from this habit that it gets the name “Marinating Coney Rat”.
They are most active in early morning and late afternoon, individuals have distinct territories, and will defend them against interlopers and competitors. Breeding occurs in spring and early summer, from March to July. Females are sexually mature at 3 months old, gestation is one month. Litter size is usually six babies, which mature very quickly; young are reared in a burrow lined with plucked underfur and dry grass. This rodent is generally solitary outside the breeding season, competitors for food are driven out, animal is most active during early morning and early evening. Lifespan is up to 5 years, they are commonly preyed upon by raptorial birds, canids and felids.

Spiny Jungle Rat (Echinorattus australis)
Order: Rodents (Rodentia)
Family: Mice and Rats (Muridae)

Habitat: mountainous rainforests of Northern Meganesia.

Picture by Pavel Volkov

Introduced rats and mice that came to live in Australia managed to compete successfully with native species, but also to find new niches as the Neocene progressed.
Tropical Rainforests in the north of Meganesia play host to a large range of fruit and nut bearing trees, which are mainly fed upon by parrots and cockatoos, but these birds only rarely descend to eat fallen fruits and seeds in such a dense understory. This is the niche taken by the Spiny Jungle Rat, a creature analogous to the agoutis of South American jungles. It feeds by gnawing open the hard seeds of rainforest trees, as well as eating the flesh and seeds of fallen fruit.
Animal reaches up to 45 centimetres in length, and has only a stubby, hairless tail, weight is up to 4 kilograms. Outward appearance recalls both its ancestor, the Brown Rat (Rattus norvegicus) and a South American Agouti, legs are fairly long, hands are grasping, hind legs are longer than forelegs, and rump is large. The head is blocky and profusely muscled, with large incisors of dark orange colour. It is supplied with defence by the presence of sharp black spines, up to 8 centimetres long, which are distributed amongst the fur, spines are denser on the rump and shoulders. Coloration is chocolate brown on the upper parts, with pale grey cross stripes, belly is yellowish white.
Spiny Jungle Rat is diurnal, solitary but very shy, and will flee when disturbed; individuals tolerate each other outside the breeding season so long as food is not scarce. Breeding occurs throughout the year, with the most young being born in the dry season. Young are reared in a sheltered scrape in the forest floor, obscured by dense vegetation; male takes no part in rearing young. Female is sexually mature at one year, gestation is around 40 days. Usually 4 young are born; these can occasionally be two sets of twins. Young reach full size within 6 months. Lifespan is up to 13 years due to defensive spines, only relatively persistent or smart predators, such as raptorial birds and predatory marsupials, may succeed in preying upon it.

Rapa Nui rat (Geomurinus brachyurus)
Order: Rodents (Rodentia)
Family: Mice and rats (Muridae)

Habitat: Easter Island.
While humans purposefully introduced some species in new habitats, others were inadvertently introduced. The rats (Rattus) followed the humans to several places, benefiting from their presence. When they were extinct, some of these rodents were able to survive and continue their evolution. In Easter Island, the populations of rodents that survived evolved into an endemic species, the Rapa Nui rat.
The Rapa Nui rat has 13 cm of body length, with a short tail of 5 cm. Their physical appearance reminds that of a Cricetidae hamster, with them having a fossorial lifestyle. They have strong forelimbs that are used to excavate the ground to make tunnels to be used as their dens. It has reddish-brown fur with a white underside and three black stripes on the back.
This species feeds mostly on fruits, roots and seeds. Insects and eggs are eaten very occasionally. They spend the day on their dens, only leaving to forage at night.
The Rapa Nui rats are very territorial and intolerant of each other, with attacks against each other being commonplace. Exceptions do occur, usually when a female and male meet when the female is in heat, but even so, the female may attack the male after mating. Even siblings, once mature, may attack one another. Same-sex groups of siblings can stay with each other until they are about eight weeks old, at which point they will become territorial and fight with one another, sometimes to the death. Infanticide is not uncommon among females, usually due to stress from the environment. They also eat their dead young.
These rodents mark their burrows with secretions from special scent glands on their hips. The males in particular lick their bodies near the glands, creating damp spots on the fur, then drag their sides along objects to mark their territory. Females also use bodily secretions and feces. They can have two to four litters per year. The Rapa Nui rat has a 15 days long gestation, giving birth to a litter of 1 to 12 that wean after three weeks of age.
It communicates by squeaking or with ultrasound. The females are sexually mature with eight weeks, while the males only become mature with six months. Their lifespan is 3 years, but many are killed by predators, such as the owl-harrier.

This mammal species was discovered by João Vitor Coutinho, Brazil.

False Hamster (Cricetimimus novazealandiae)
Order: Rodents (Rodentia)
Family: Mice and Rats (Muridae)

Habitat: Open country, scrub and light forest, vegetated mountainsides, North and South Islands of New Zealand.
The house mouse (Mus musculus) was a ubiquitous pest of mankind in the Holocene, and it made its way to wherever man came to settle. Plagues of mice would often occur on grain farms, and infestations in human dwellings were common.
In the Neocene, apart from rather typical kinds of mouse, New Zealand plays host to various Murids with a somewhat more specialized lifestyle, like the False Hamster. This animal is far more common on the cooler, drier South Island, where open country is more prevalent, North Island populations are smaller in size and more sparsely distributed. Adults reach 15 centimetres long and weigh up to 50 grams, having only short, stubby tails, physical shape is rounder and more robust than its ancestor, with large cheek pouches for storing food. Coloration of fur is a dark reddish brown with a yellowish belly, face is marked with a whitish “mask” , feet, nose and naked tail are pinkish. Its diet consists of various grains and seeds as well as the stems of grasses, and insects occasionally. These animals use their cheek pouches to store large amounts of food underground.
Individuals are solitary and indeed anti-social outside the mating season, and live in small, deep set burrows, in which they sleep, store food, and raise their young. This rodent is most active in the twilight and early evening. Males and females make glandular secretions in order to mark and maintain territorial borders, and a latrine is left near the burrow for this purpose also. Call is a rather typical squeak, a high chirp, hissing when alarmed or fighting.
Sexual maturity is reached at 8 weeks, and females come into oestrus multiple times per month, gestation is 25 days. Litters consist of up to 10 babies, the mother will nurse them for a short period of time, and if she feels threatened, may kill and eat her pups. Lifespan is up to 3 years.

This species of mammals was discovered by Timothy Donald Morris, Adelaide, Australia.

Causeway Mouse (Commutomys semistriatus)
Order: Rodents (Rodentia)
Family: Mice and Rats (Muridae)

Habitat: tropical savannahs and semideserts of Central and southern Africa.

Picture by Wovoka

Animals commonly evolve habits and specializations in order to avoid predation, rodents seem to have excelled at this, from kinds with spines to poisonous forms, to ones that run quickly. One such example of predatory avoidance in habit is the Causeway Mouse.
This rodent is generally unspectacular in appearance, small, pale brown with indistinct dark longitudinal stripes, in shape generally very much like a typical mouse, apart from legs and feet which are longer and more slender. Head and body reach up to 10 centimeters long, with the tail reaching a further 10 to 12 centimeters, weight is up to 30 grams. Descended from Striped Grass Mouse (Lemniscomys striatus), it has passed to a diet of insects, fallen berries, and the softer parts of herbaceous plants.
The habits of this animal are extraordinary. It clears paths in the grass which it runs along to access areas where it usually feeds, this is not so unusual, some small mammals of human era did this. But what is unusual is that it protects itself by enclosing these pathways in a dense latticework of grass stems which act to form tunnels out of these paths, from this habit it gains the name “Causeway Mouse”. When these tunnels are disturbed or damaged, the mouse proceeds to mend them, and they are being maintained constantly, with new ones being made when food sources fail. These tunnels serve to conceal it from nearby predators, a nest which is a globular bundle of woven grass stems, sits at the centre of its territory, most often sheltered beneath a bush or in lee of a rock or fallen tree.
It is diurnal and solitary, being most active in the morning. Breeding occurs year round, a male will venture out of his usual causeways in search of a female’s nest, with which he may visit to breed multiple times a year. Oestrus cycle of the female is about six days, and oestrus lasts a day and a half, gestation is twenty days. Young are born blind and hairless, maturing and weaning at 30 days. Lifespan is up to 2 years. Predators include small cats and various birds of prey, some kinds of predator may be smart enough to make a hole in the tunnel, and wait for this mouse to pass, in order to catch it.

Hawaiian mole mouse (Xenospalax subterraneus)
Order: Rodents (Rodentia)
Family: Pacific mole mice (Xenospalacidae)

Habitat: Hawaii (Big Island), ground in valleys and woods.
Before human occurrence at Hawaii mammals were absent at islands and only insects and their larvae could occupy an ecological niche of underground digging animals. But historical colonization epoch the fauna of islands had replenished with various animals, alien to indigenious fauna on fault of people. At Hawaii various species of ground mammal, which began to develop ecological niches inaccessible to birds, had appeared. Moles and other digging animals were not introduced to Hawaii, but their place uniquitous rodents had occupied: they are descendants of mice avoiding a competition to descendants of two species of rats, also introduced to islands by people.
The ground in woods of Hawaiian Islands is penetrated with set of underground burrows in which their builders - completely blind rat-sized animals – run. By body shape they are similar to mole rats (Spalax) living in Eurasia, but they are descendants of house mouse. Therefore they are named Hawaiian mole mice. They differ from true mole rats in features of behavior: if true mole rats frequently left on the ground surface for feeding, their Hawaiian “doubler” does it extremely seldom, eating only roots and tubers of plants.
Hawaiian mole mice are similar to continental species by features of anatomy developed at both groups independently. At them there are the same cylindrical body, short paws and large head. Main digging adaptations of Hawaiian mole mouse are its head and strong incisors. Skull of this animal is wide and short, and incisors of top jaw are very big. Lips of animal densely close mouth from the ground by special outgrowths, not impeding incisors. Occipital muscles are very strong, for their attachment on back edge of skull of the animal the special crest stretches. Muscles lowering head are also strongly advanced. During the ground digging this small mammal lifts head making effort and ramming a vault of formed hole, and then lowers it, ploughing by incisors deep furrow in the ground before itself. Animal rakes away the loosened ground by forepaws under stomach and pushes it out from hole, or simply stamps by paws.
This animal is completely blind, and its eyes are reduced even in greater degree, than at moles – eyeballs are abscent and the optic nerve had reduced. The top of head and shoulders of Hawaiian mole mouse are covered with thick cornificate skin – animal forms a vault of hole by them. Corneous armour on head closes the place where ancestors of this animal had eyes, and also covers nose from above. It is additionally strengthened with bones of skull of animal grown together in continuous osseous vault.
Because paws do not accept direct participation in digging, they are rather short. Animal only rakes away the friable ground back by them. Tail of Hawaiian mole mouse is also very short and hairless. Animal is covered with velvety fur of black color. On muzzle of Hawaiian mole mice long whiskers, with which help animals are guided in space of underground courses, grow.
Hawaiian mole mice build extended systems of burrows in wood, and arrange the special drainage tunnels through which the water leaking to burrows because of daily rains is removed from them. As animals are vegetarians, the competition between them is not as sharp, as, for example, at moles. Hawaiian mole mice eat roots and tubers of plants, and even parts of such species which are not eaten by other animals.
Hawaiian mole mice breed practically the year round. For one year the female can draw up to five hatches numbering 6 – 8 cubs. They grow quickly, and at monthly age already begin independent life. At three-monthly age they already can give birth to posterity. But, despite of such high rate of breeding, the significant amount of young growth perishes: when the colony appears overpopulated, the part of its inhabitants (mainly young animals) feels stress. It occurs because of too big frequency of meetings between animals, and less strong animals aspire to leave earlier safe holes. At this time animals frequently settle not in systems of holes, but on the ground surface. It happens that such animals movable by aspiration to avoid of stress appear on ground surface in day time, run in wood, not trying to hide, and at times even try to force rivers. The significant part of these of “victims of stress” perishes, but some ones succeed to leave far enough and to found a new settlement.
Under the ground one of main dangers – the descendant of intruder like them, the large digging blind snake catches Hawaiian mole mice. And on the ground surface local predatory birds, and even descendants of rats catch them.
At the next islands of the Hawaiian archipelago there are close species of these rodents:
Mole mouse of Lanai Island (Xenospalax lanaiensis) is the small species (equal to large mouse in size), distinguished by spotty colouring: on light grey background there are dark spots. Separate individuals of this species are almost completely black. This species has similar biology, but spends more time on ground surface. At night it leaves to feed among bushes.
Mole mouse of Maui Island, or half-naked mole mouse (Xenospalax mauiensis) differs from other species in strange appearance: the fur of yellowish-grey color had remained at this species only on the bottom part of body and on shoulders. Head, back and sides of this rodent are hairless, covered with rough grayish skin. This rodent lives in warm rainforests, and is able to swim well. The young growth can even settle during floodings.
Giant mole mouse (Xenospalax giganteus) lives at small Kahulawi Island near southwest coast of Maui Island. It is the largest species of genus: the length of body reaches 25 cm. It differs in greater, than at other species, propensity to leave on ground surface. Its wool is colored rusty-brown color, and corneous “helmet” on head is rather small.

Cataphractherium (“armored beast”) (Cataphractherium protectus)
Order: Rodents (Rodentia)
Family: Porcupines (Hystricidae)

Habitat: forests of Zinj Land, the broken sites of forest stand with plentiful grassy vegetation.

Picture by Tim Morris

In Neocene rodents had an opportunity to pass to large dimensional class. Earlier this process proceeded on the Earth in limited scale – really large species appeared in Neogene of South America, and in other continents this group was represented by rather small animals. Extinction of large species of animals in Holocene has enabled rodents to occupy new ecological niches and to become larger species. The increase of size took place independently in different groups of rodents. Huge mighty grasscuttes, kangoohoppers and giant kangaroo jerboas live in Old World of Neocene epoch. And at the East African subcontinent, in Zinj Land, the unusual representative of Old World porcupines, cataphractherium lives. It is a large porcupine of massive constitution – weight of adult animal reaches 200 kg, body length is about 150 cm not including tail. This animal has convergent similarity to large ground porcupines of North America and stegoechidna from Meganesia – it moves on four legs, sometimes rears on hind legs and actively uses forepaws for food getting. This is a plantigrade animal with large head and long tail.
The anatomy of skin of cataphractherium is unusual: it is an animal chained in bone-corneous “armour” similarly to extinct ground sloths of late Cenozoic (hence the name: “cataphractus” means “armored” in Latin), but having means of active defense. Needles, characteristic for true porcupines, have lost function of thrust weapon at cataphractherium. On back and sides of this animal needles are truncated and became very thick. They have lost mobility and have turned to corneous plates of wide pyramidal shape with the dulled apex. On neck they are joined to cross lines, and on trunk form something like “cobblestone road” with chaotic arrangement of plates. Inside these plates located along a backbone the centres of ossification are formed, and at old animals the corneous tissue of plates is gradually replaced by firm bone. These plates are mostly immersed in thickness of skin and only tops jut outside. They are hidden with rich wool of ash-grey color, darker on head and shoulders.
Cataphractherium is a sluggish herbivorous animal to which it is vital to be able to render worthy repulse to predators. Tail of this animal has turned to truly dangerous weapon. It is strong and muscled, because at food getting heavy cataphractherium supports on it. The spikes, inherited from ancestral porcupines, had changed and had turned to strong corneoud “daggers” on the tail of this animal. Terminal vertebrae of tail are fused together, having formed a kind of “mace”, as at prehistoric ankylosaurs. Lateral shoots of “mace” vertebrae are enlarged, and “mace” has flattened shape and rounded outlines. The bottom surface of “mace” is covered with small prickles, which rest against the ground when cataphractherium reaches to branches of low trees, having reared on hind legs. “Dagger” spikes grow on edges of this “mace”, and on its top part there are some corneous plates. Defensive tactics of cataphractherium is very simple – it meets a predator, standing on four paws and swinging tail. If the predator attacks, animal makes impacts to its legs and stomach by tail. Easily turning on hind legs, the animal constantly turns sideways to predator and keeps up its movements.
Beyond the danger this animal behaves very peacefully. Males may display aggression to each other only at the presence of the female ready to pairing. Thus they try to frighten the contender, striking impacts by tail on grass and thin-stalked bushes and making a lot of noise. If the contender does not recede, males combat, having risen on hind legs and “boxing” by forepaws. As cataphractheriums live in tropical climate, the courtship season is not expressed precisely, though the majority of females is ready to pairing in rainseason.
Cataphractheriums are peaceful foliage browsing herbivores. They eat greenery of undersized trees, bushes and large grassy plants. Powerful incisors allow them to bite off young branches of bushes and fibrous leafstalks of grassy plants. With the help of long claws on forepaws cataphractheriums dig the ground in searches of tubers and rhizomes of plants. It is a solitary species of animals: only the female and its posterity keep together.
The female gives rise to two cubs once a year. The young growth is not protected by plates – they start to grow only at the age of two months. Cubs have soft wool and spotty colouring – on dark background there are randomly scattered black spots. As corneous plates grow, spots disappear, being kept for longer time on shoulders and head. Young animals quickly learn to eat food of adult animals, but are fed with milk up to five-monthly age, and further require only protection and the help in getting of vegetative forage. Usually at this time female is already coupled again, and the young animal leaves mother shortly before birth the next cub at her. The young animal reaches the size of adult individual at the age of three years and becomes sexually mature the same time.

This species of mammals was discovered by Simon, the forum member.

Otter dormouse (Glirolutra hamiota)
Order: Rodents (Rodentia)
Family: Dormice (Gliridae)

Habitat: southeast of Europe, valleys of rivers running into Fourseas.

Picture by Alexander Smyslov

The last congelation at the boundary of Holocene and Neocene in had radically changed the geography of Eurasia. The glacier had moved huge masses of the ground as if huge “bulldozer” and has changed the direction of current of European rivers. Only the lower reaches of Dnepr, Don and Volga rivers had remained approximately in the same places, as in human epoch. But their upper courses are already absolutely different, rather than in human epoch. Number of inhabitants of European fresh waters had been reduced in great degree, and many fish-eating animals had died out. In particular, European otters were among them. Earlier their number was undermined by people, and it was an additional factor caused their extinction.
After glacier thawing in early Neocene, when fresh waters of Europe had returned to the territory occupied earlier and had formed new river channels. In rivers freshwater fishes and crustaceans had settled again, but otters did not hunt them any more – they had died out irrevocably. However, such favourable ecological niche has not remained empty - rodents had undertaken a role of fish-eating river predator. It is remarkable, that in South America about the same situation had taken place in parallel and independently, but the descendant of completely another animal became aquatic predator there.
And in Europe the role of Neocene “otter” is played by the descendant of fat dormouse (Glis glis), by otter dormouse. It is rather large rodent: it is approximately equal to marten in size. Top side of body of this animal is gray-brown; throat, breast and stomach are milky-white. Fur is very dense and rich; animal spends a lot of time looking after it and greases it regularly with fatty secretions of special glands. Head of otter dormouse is pointed, ears are small, and muzzle is lengthened. On muzzle there are very much advanced rigid and long vibrissae, helping to be guided even in muddy water.
The basic body of underwater movement represents hind legs with long toes between which membranes are advanced. In addition this rodent swims with the help of wide and flattened tail similar a little to beaver’s tail. Forepaws are shorter, rather than hind ones, and at movement they are pressed against chest. Fingers lack of membranes, but the claws are advanced, and finger pads are very sensitive.
The basic food of this rodent includes fish catching by otter dormouse in thickness of water. Occasionally it eats large crustaceans – crayfishes and large scuds. This rodent kills small prey (small crustaceans, tadpoles, fish fry and insects) by bite and hides in cheek pouches. Having emerged on surface of water, otter dormouse eats the saved up prey. Otter dormouse eats large fish on land, holding food in forepaws.
Otter dormice live in clans, forming small settlements on riverbanks. Such colony totals up to ten adult animals, and also some individuals of young growth of the present year. “Lair” is arranged in holes in riverbanks. Holes are located no farther than one meter from each other; the single rodent and growing up posterity till some time lives in each one. Occasionally among otter dormice the convinced singles appear. They are less conservative in a choice of refuge and sometimes settle even in hollows of trees or in nests of large birds, arranging “ground floor” under nest (due to tenacious claws this rodent is able to climb up trees). But life alone for this rodent is rather compelled circumstances, than a rule. But the clan of these animals represents simply some individuals living nearby from each other and not connected with relationships in the majority. At them the hierarchy constructed by a principle of strict matriarchy is established: females are larger than males and settle in the center of colony.
During the hunting each rodent operates separately and does not miss an opportunity to steal prey at weaker individual. Therefore the young growth, leaving mother, stays in colony rather seldom, especially if the place is not too rich in food. The only thing uniting these rodents is the danger. Even large wide-headed catfishes are afraid to attack group of these rodents, preying only young or single animals.
Otter dormice have voice and can utter some different signals based on whistle. Loud whistle is, perhaps, a sound most important for them – it’s a signal of threat from air: birds of prey are usual enemies of these rodents. Rolling chirring is a signal of underwater alarm. At occurrence of a stranger from other clan, or a single individual, old residents of colony meet it with sibiliant whistle, accompanying it with threating poses. If the shortage of food takes place, otter dormice may be aggressive to strangers.
Despite of descending from dormice, these rodents keep activity in winter. They punch thin ice on river surface with claws or gnaw it through. But usually in habitats of these rodents river does not become covered by ice – otter dormice do not settle far to the north.
Two times per one year the female gives rise up to 5 – 6 cubs. They come into the world blind, but covered with wool. The first litter is born when winter colds have not passed yet, and the second litter appears in the middle of summer. Shortly before it female banishes the previous posterity. At one-year-old age young animals begin able to bring posterity.

Mountain dormouse, chinchilla-dormouse (Raptoglis chinchilloides)
Order: Rodents (Rodentia)
Family: Dormice (Gliridae)

Habitat: mountains of Caucasian peninsula, Middle East.

Picture by Alexander Smyslov

In early Neocene rodents got an opportunity to prove once again their evolutionary success. They evolved quickly, occupying all habitats suitable for them, and already in early Neocene their specific variety was comparable to the level of Pliocene and an early Pleistocene, before the epoch of anthropogenous pressure. In Neocene rodents are widespread everywhere on Earth, except for Antarctica – from equatorial forests to cold northern meadows and tops of mountains.
In Eurasia in Neocene there were some species of dormice family which use food of animal origin much more often than their ancestors. These are the sable dormouse (Raptoglis zibellinus) from Three-River-Land steppes and the otter-dormouse (Glirolutra hamiota) from rivers of eastern part of Europe. One more species closely related to them lives to the south from Fourseas, in mountains of Caucasian peninsula and mountains of the Middle East – it is the mountain dormouse called also the chinchilla-dormouse for its thick warm fur. This representative of northern fauna prospers in the south exactly thanks to dwelling in cold highland climate.
The mountain dormouse is the large rodent reaching weight of about 3 kilograms and the size of a small cat. Due to tail covered with long wool the animal seems even larger. The head of this rodent is rounded, has shortened muzzle and small ears covered with wool from outside. Mountain dormouse has large eyes and good sight.
This species mastered successfully life in highlands due to thick fur which helps to keep heat even in hard frost or at the great elevations. Summer fur of this animal is reddish-brown, velvety and rather short. There always is a white spot on breast and throat, head top is darker. Winter fur differs in greater wool length and thickness, and also in lighter coloring.

Picture by Alexander Smyslov

Constitution of this animal is solid, and paws are short (hinder legs are rather longer than forelegs). Fingers and toes are armed with pointed claws due to which mountain dormouse is capable to climb on almost steep mountainsides and among a bush. This animal can make leaps up to 2 – 3 meters long.
Mountain dormouses are almost exceptionally zoophagous, adding to their diet no more than 10% of vegetable food, though in case of starvation they can temporarily turn to completely vegetative food. These rodents often eat carrion, searching for it by smell. Additionally mountain dormouses readily gnaw even bones. For them the habit to search and to pull down bones to “bonemill”, a special place hidden from predators, where these animals gnaw their finds, is characteristic. They almost completely assimilate collagen from the eaten bones, and the remains are insignificant. Usual prey of mountain dormice includes small rodents, birds and their eggs, and reptiles and insects in lowlands.
This species of rodents lives singly and rarely in couples. The female is more aggressive than male. The shelter of this rodent represents the deep hole made between stones in the way hardening the digging out of the hole by predators.
Like other representatives of family, mountain dormice fall the long hibernation which can last up to half a year with short breaks. Animals grow fat intensively to the winter, gaining the weight of about 4,5 kg. Fur becomes longer and denser. During the winter the animal wakes up for several times to leave the dung, which is very condensed and dry at this time.
The posterity is born at the end of spring when there is a lot of food. The litter numbers up to 5 cubs which grow quickly and at the age of about two weeks already start tasting meat. Sometimes at the end of summer animals can have the second litter in which only sometimes there are more than two cubs. Life expectancy doesn’t exceed 5 years.

Viverrine Dormouse (Viverroglis maculatus)
Order: Rodents (Rodentia)
Family: Dormice (Gliridae)

Habitat: Southern Europe, areas bordering Mediterranean hypergaline swamp; Middle-east, forests, woods and scrub.
Specialized forms of rodent carnivorous in diet can be found in the Neocene, among them the Predatory Dormice (Raptoglis). Relatives of these, descended from a common ancestor, are less specialized in diet and just as adaptable, Viverrine Dormouse. Living in forested areas of southern Europe and the Middle-east, this rodent somewhat resembles the Sable Dormouse (Raptoglis zibellinus), but is a bit more elongate in shape, legs are more bent and claws larger. Animal is an analog of the genets and civets of Holocene, feeding not only on small vertebrates, but insects, fruit, fungi and large seeds. It is an opportunist, eating whatever is most available; in part of range bordering the Mediterranean swamp it may feed profusely on wild olives.
Viverrine Dormouse is a fair sized animal, reaching a weight of 4 kilograms, animal seems longer due to low build and long torso and tail. Tail is long and used for balance, legs are short and bent, claws on all four feet are large and curved. This species climbs trees well and spends a good deal of time there. This animal is very agile and can leap between trees, or make pouncing jumps onto prey. The face is pointed and the base of the skull is long, nose is bare but the face has long whiskers, feet are bare. Ears are relatively large and bare on the inner surface.
Its fur is fairly short (except on the belly), giving it a sleek appearance like a cat, colouring is light yellow brown with numerous dark brown spots and cross stripes, tail is banded with a white tip.
Generally solitary, they are not averse to their own kind and may form couples. Unlike its relatives, it nests in trees, preferring a large tree hole or broad fork in the crown of the tree.
As opposed to its relatives, this animal does not hibernate but it may become less active during the cold of winter.
Breeding occurs in late winter and early spring. Up to 5 young are born and they develop very quickly, eating solid food within 3 weeks. Sometimes pairs make a successful second litter in the early summer. Lifespan is up to 5 years, predators and competitors include carnivores like cats and true civets, as well as large birds of prey.

This mammal species was discovered by Timothy Donald Morris, Adelaide, Australia.

Giant kangaroo jerboa (Macrodipodes wallabiiformis)
Order: Rodents (Rodentia)
Family: Jerboas (Dipodidae)

Habitat: steppes of South-Eastern Europe, along the Fourseas coast to Middle Asia.

Picture by Alexey Tatarinov

Steppe ecosystems of Eurasia before the beginning of the vigorous human activity had not conceded to savannas of Africa in biological efficiency. Various hoofed mammals – aurochses, wild horses and antelopes – had been dominant species of steppe herbivores. People ploughed steppes, transforming these areas into primitive agrocenoses, and exterminated steppe animals. The result of human activity was a degrading of steppe ecosystems by the end of human era. In Neocene the population of newly appearing ecosystems had been formed, actually, from zero. In the Euroasian steppes of temperate climatic zone representatives of new groups of herbivorous mammals dominate – porcippulas, cursorial boar relatives, gracile harelopes, and some other forms of herbivores. Among new steppe herbivores of Neocene large representatives of rodents took the important place. In Neocene rodents represent one of the most successful orders of mammals.
Jerboas were the characteristic group of rodents of the Old World lived in open spaces. In ice age at the boundary of Holocene and Neocene, in conditions of desertification and deforestation, some representatives of jerboa family had got a wide distribution and had considerably increased in size. This adaptation, favourable in conditions of cold climate, has allowed one species of these rodents to occupy an ecological niche of the analogue of small antelopes in steppes of Eurasia. This animal is giant kangaroo jerboa, a gregarious middle-sized mammal.
This rodent has kept features of anatomy, characteristic for family representatives, adjusted for the giant size: the animal weighs up to 15 kg. In behaviour and a habit of movement giant kangaroo jerboa is similar to small kangaroos like wallaby. The body length of this animal reaches 60 cm, and tail is about one meter long. Long strong tail at this rodent serves for support when animal eats, bringing food to the mouth by forepaws. Giant kangaroo jerboa moves almost exclusively on rear legs, accelerating momentum up to 70 kms per hour In case of danger it makes jumps up to 6 meters long. At jumps tail of animal serves as the balance weight. On the tip of tail the switch of white hair is advanced.
Ears of giant kangaroo jerboa are rather short and rounded. This animal does not dig holes, and does not run into hibernation in winter – these changes of behaviour are consequences of increase of body size. In winter this animal keeps activity, and it does not need overcooling.
Summer wool of giant kangaroo jerboa has sand yellow color with small dark spots merging to short cross strokes on back. In winter the wool of animal turns lighter in color and becomes thicker. At this species of rodents wool is weakly attached to skin. If the predator will seize this animal, wool easily drops out and allows the animal to escape from its teeth. Moreover in winter “dress” at giant kangaroo jerboa “ski” grow on feet – it is a border of rigid wool. This adaptation helps an animal to jump easily on snow, not falling in.
In summer giant kangaroo jerboa is a solitary animal. Each individual has territory, and its borders are marked by urine and secretions of smell glands. The centre of territory is a hole or any other ready shelter. Giant kangaroo jerboa is not able to dig a hole itself, therefore it uses ready shelter – usually holes dug out by goliath mole rat, huge local rodent. Usually the territory with a hole is occupied by female. Males are not so choosy in the choice of shelter: rich bushes as shelter are frequently enough for them.
This species of rodents has rather long pregnancy time, and the female brings only one litter in one year, in which there are about 5 cubs. Newborn cubs are helpless and female hides them in hole, closing an entrance with a bunch of prickly grass or bush pulled out from the ground. Cubs are born in the beginning of summer, and within the first month of life they do not leave shelter. The female watches the vicinities of shelter, and if necessary it is ready to distract a predator in order to withdraw it far away from shelter. Cubs behave very cautiously, even having learned to move. While the female is near to posterity, cubs can leave a hole and play, but at a first sign of danger they hide in. The posterity leaves a hole for ever at the age of about one and a half months. At this time colouring of cubs is cross-striped, that helps them to mask in grass better. It is the only protection of young animal. Usually young animals wait for returning of the female, having hidden in grass. In case of need cubs can escape from the enemy, quickly jumping and sharply changing direction of movement. When danger passes, they come back to a former place, waiting for the female returning. At the same time young animals begin to eat plants. At the end of summer the litter is fed in territory of the female, gaining weight. Young animals become independent to an autumn, having reached the weight of 8 – 9 kg. This is a very important time in their life: the young animal, not having accumulated a sufficient stock of hypodermic fat, easily becomes a victim of frost. In the first winter about a half of the young growth born in summer perishes because of various reasons. But the next year in autumn females become capable to pairing, and at the age of two years, after the second wintering in their life, they bring posterity the first time.
In winter, when it is more difficult to find food and danger of predator attacks is more probable, giant kangaroo jerboas gather to herds numbering over fifty animals, and wander on extensive territory. In spring, when snow thaws, the common territory of herd is broken into individual sites, and animals become solitary ones again.

Bush-climbing jerboa (Galagops scandens)
Order: Rodents (Rodentia)
Family: Jerboas (Dipodidae)

Habitat: Central Asia, bush thickets.
At the boundary of Holocene and Neocene ecosystems of the Earth had passed through a short-term stage of impoverishment of specific variety. As a result of human activity and climatic changes the majority of large species of vertebrates had died out. However, this process was accompanied by outburst of number and growth of specific variety of small mammals, mainly of rodents. In course of evolution these animals adapted to inhabiting in newly formed ecosystems. One example of this process is a small species of rodents from Central Asia, bush-climbing jerboa. Approximately 10 million years after end of Holocene congelation, when climate became humid, the area of steppes and semideserts of Central Asia was reduced, and they had partly given up the place to hardy bushy vegetation. The part of animal species lived in these places had died out, but some steppe species managed to adapt to inhabiting in places of new type of vegetation. Rodents have successfully mastered these habitats, having formed a significant amount of new species. Bush-climbing jerboa is one of them; being a descendant of certain low-specialized species of this family, it has developed a new way of movement – climbing and jumps among branches.
This small-sized rodent is a little similar to bushbaby prosimian in shape and a manner of movement. Bush-climbing jerboa reaches length of 25 cm; tail is up to 50 – 55 cm. Its rear legs are lengthened and have narrow long foot and short mobile toes. Forepaws of animal are also prehensile. Bush-climbing jerboa jumps in branches on rear legs, using tail as a balance weight, but it also can move in “galloping” movements, seizing branch alternately by front and rear paws. It is capable to climb down along tree trunk turning a tail downwards, but simply jumps off right on the ground from undersized trees and bushes (up to 3 meters high). This animal prefers to live in top part of tree crones where there is an opportunity to make long jumps. At the contact with branch toes of animal automatically grasp it.
Ears of this rodent are short, rounded and wide. They do not prevent to move on branches, but help to catch environmental sounds and serve as the good device of heat radiating. In hot weather blood vessels extend, and animal moistens external surface of auricles with urine at which evaporation there is better heat radiation.
Wool of bush-climbing jerboa has yellowish-brown colouring with several longitudinal strips of brown color; stomach is white. On tip of tail there is a switch of black color with white top. With its help animal gives signals to relatives and distracts attention of predators.
This is an omnivore eating seeds and buds of plants, and also small insects. Having an opportunity, bush-climbing jerboa can ravage bird nests. This rodent frequently lives near bushgophers, repairs their abandoned shelters and occupies them. In winter this rodent runs into hibernation. It spends winter in reliable shelter – usually in deep holes of other species of rodents. Frequently some animals gather and run into hibernation in common hole. Animals close the entrance to this hole with plug of dry grass. Feeling rigorous winter, animals may make some grass plugs.
Within spring and summer female has time to give birth to two litters of three – five cubs. To give birth to posterity the female uses abandoned bird nest in which it simply drags more stalks and leaves. Cubs are born naked and blind, but develop quickly. At the age of two weeks they already study to climb on branches.
In warmer areas of Eurasia bush-climbing jerboa is substituted by close species: grass-hopping jerboa (Galagops minusculus). This is dwarf similarity of bush-climbing jerboa: the adult grass-hopping jerboa is mouse-sized animal. It lives in thickets of high grasses, eats grains of various degrees of ripeness. In spring this little mammal eats buds and flowers of plants, insects and their larvae. It inhabits steppes of Three-Rivers-Land, and is spreaded to the west along northern coast of Fourseas. Grass-hopping jerboa frequently occupies a part of hole of digging rodents, peacefully getting on with hole owners.

Canadian haremouse (Megazapus canadensis)
Order: Rodents (Rodentia)
Family: Jerboas (Dipodidae)

Habitat: northern North America, Greenland.
Neocene has become the time when the descendants of small animals, who gained an advantage in survival in the human era, began to break out of their size class, occupying the ecological niches of larger species. Thus, in Eurasia, wolf-sized descendants of hedgehogs appeared, alongside with the descendants of hares, which replaced deer and antelope in ecosystems. In North America, this phenomenon is pronounced not so clearly, but even there dwarfs have made an attempt to turn into giants. They can be called “giants” rather conditionally: it’s just that the descendants of some species of small rodents have become significantly larger than their ancestors, although they still remained in a small size class.
These species include the Canadian haremouse, a descendant of the Holocene species Zapus hudsonius. It is a fairly large animal by the standards of murine rodents – growing about 40-50 cm in length (including tail), and weighing about 1.5 kg. The animal’s body is covered with grayish or reddish-brown fur, which becomes lighter and thicker by winter. Unlike the white hares of the human era, this animal does not turn white in winter. There is a dark, almost black stripe on the head that stretches between beast’s ears. The stronger the individual, the darker this stripe.
In addition to its size and ability to change wool color, the Canadian haremouse has developed specific body proportions close to those of a rabbit: the front part of the body has become heavier, and this rodent moves not on its hind legs only, but on all fours. Only in case of danger can the animal jump only on its hind legs for a while, but it quickly switches to a galloping run. It tail has changed – it has become thicker and shorter, covered with thick hair and serves both as a counterweight to the larger head and front of the body, and as a fat reserve for the period of winter starvation.
Canadian haremouse is an exclusively herbivorous rodent: in summer it feeds on herbaceous plants, and in winter it browses on dwarf trees and shrubs of the North American tundra, follows larger herbivores that dig up and scatter snow, and eats up the remains of plants behind them. Less often, this rodent digs food out from under the snow on its own. In winter, this species can eat carrion, but it does it rarely, only in very extreme cases. This animal itself is hunted by various birds of prey and animals like waheelas, keeluts, etc.
Canadian haremouse does not form permanent groups. Usually, several representatives of this species graze together, but without interacting with each other, near larger animals like umingmacks: some ones eat, while others inspect the surroundings in search of danger. These groups are mixed; there are both males and females in them. Rodents usually do not form stable families, but Canadian haremice form more or less permanent breeding pairs for one season. In late winter and spring, males fight for females while establishing a hierarchy. Females do not take part in this struggle, but they clearly prefer high-ranking males.
To raise offspring, Canadian haremouse builds a nest – in a dry patch of soil under the roots of a tree, the pair digs a hole. When doing it, the partners gnaw and scratch even hard clay soil. The length of the burrow reaches 3-4 meters, there is one sharp S-shaped bend in the vertical plane in the burrow, which makes it difficult for predators to enter the burrow and saves the burrow from flooding with meltwater.
Cubs (3-4 ones) are born after 5 weeks, and unlike most rodents, although they are blind, they are already covered with well-developed fur, and their eyes open in the second week of life. The female feeds them with milk for about 3 weeks, and the male drives the predators away from the shelter, and usually does it quite successfully. In summer, young animals actively feed and stock fat for the upcoming wintering, and the females bear a second brood, born in the middle of summer. In late autumn or winter, families break up; sexual maturity in this species occurs by the following spring, even in the offspring of the summer generation. The average life expectancy of Canadian haremouse is about 5 years, but most of the animals die at an earlier age, especially in winter.

Giant wood porcupine (Aepythizon megatherioides)
Order: Rodents (Rodentia)
Family: Wood porcupines (Erethizontidae)

Habitat: woods at plains and mountains of northwest of Northern America (to the west up to southern areas of Beringia).

After extinction of plenty of hoofed mammals species at the border of Holocene and Neocene other herbivore mammals had occupied become empty ecological niches having caused fantastical species. There were rodents among them, huge by variety order including in Holocene basically small and absolutely tiny species. Certainly in various epochs of Cenozoic rodents more than once “tried” to come to middle- and large-sized class, and sometimes it happened most advantageously: the rhinoceros-sized rodent lived in South America and Pleistocene North-American species of beavers reached the size of bear had appeared among them. In Holocene largest representative of this group were beaver and capybara lived in rivers. But in Neocene having occupied various ecological niches rodents have fairly increased their size. In South America among rodents forms similar to antelopes and pigs, and also giants similar to ground sloths of Pliocene and Pleistocene have appeared. At the territory of Mexican plateau the bear-sized porcupine has lodged in Neocene. But in wood zone of Northern America this porcupine has even larger relative.
Giant wood porcupine is very large representative of Neocenic rodents (it weights up to 1 ton; growth of animal standing on hinder legs is up to 3 meters, general length is over 5 meters including tail). Back legs of this animal are longer than front ones; due to it animal can stand on two legs eating plants. Feet of hinder legs are covered with thick cornificate skin therefore animal equally easily can walk both on stones heated up by sun and on winter ice. It is a herbivorous animal; its food includes leaves and branches of various deciduous trees. In winter giant wood porcupine can eat even poorly nutritious branches of coniferous trees and roots digging out from ground. On forepaws of porcupine there are curve claws with which help animal gets food to itself and effectively protects from enemies. When the animal moves on four legs, it leans against lateral surface of fingers, claws thus are directed by tops to each other.
This species of animals lives in temperate zone frequently rising highly in mountains. Therefore in winter it should endure rather strong frosts. Fur helps it to do it becoming to winter thicker and denser. Colouring of fur is changeable, as well as at its desert neighbour: there are variants of colouring from light brown up to grey and straw-coloured. In fur the main protective weapon of the huge wood porcupine is hidden – very thick (up to 2 cm at the basis) needles up to 40-60 cm long. They are especially numerous on neck (from above and from sides) and shoulders and then grow by strip along back (up to the basis of tail). Thus, all places which predator prefers to attack are reliably protected. Needles are mobile; animal can lift and lower them depending on a situation. Sometimes (especially if the predator is weak or inexperienced) giant porcupine itself can attack it, striking impacts by needles growing on shoulders. Besides it can strongly bite by huge incisors. During fight the porcupine roars for frightening. But usually adult animals seldomly show their abilities: while they are strong and healthy they practically have no enemies. And cubs of huge porcupines can become easy catch of predators departing far from mother.
At the female in pack there are 1-2 cubs. The new litter appears once a year, but young growth long time stays with the female: last year's cubs continue to feed with mother after birth of new ones, abandoning her up to the time of sexual maturity (at the third year of life). Cubs are born without needles being overgrown by them at the first month of life. But the newborn wood porcupine is covered with wool, can see and already in half an hour after birth studies to walk. The wool of cubs of the first year of life is dark but after the first winter, during spring moult, colouring is shown which the animal will have all next life.
Sexual maturity comes at the third year of life. At this time young animals are already independent, and take part in courtship games which take place at the end of summer. On borders of individual possessions battles of males for the right of pairing with females happen. But these tournaments are not as substantial as at the desert bear porcupine: usually two males battle for one or two females. But fights happen fierce seldomly: more often all events may end by might demonstration. Contenders peel bark on tree trunks, pull out bunches of grass from the ground, urinate trees plentifully and snort loudly. Females observe of the duel from the side stimulating contenders by characteristic rumbling and spraying strongly smelling urine.
Pairing proceeds not for long and animals miss soon. But during carings the excited males can take cubs of any female for contenders and attack them. Frequently grown up young growth survived in winter and has got stronger, perishes from attacks of males in courtship season. But porcupine has successfully survived in youth can live about 60 years.

Striped tree porcupine (Bradycoendu lanceolatus)
Order: Rodents (Rodentia)
Family: Wood porcupines (Erethizontidae)

Habitat: woodlands of South America.
At the border of Holocene and Neocene, when the most part of rainforest of South America disappeared as a result of global cooling and climate aridization, the most part of tropical rainforest animals died out or had to change the way of life to survive. Among them there were various New World porcupines from South America, quite unusual rodents, which felt safe from the numerous enemies due to their quills.
Among mammals, rodents express a very wide adaptability, and have adapted to live everywhere, from the mountain slopes to fresh water. Some of their Neocene descendants even turned to marine animals, but the evolution of South American porcupines did not reach such extremes. Most part of them (for example, the sidespiny porcupine) still represents tree-dewelling animals, but there are exceptions in any rule, and the striped tree porcupine is one of these animal exceptions.
Striped tree porcupine is a relative of sidespiny porcupine and is a relatively large rodent, reaching almost 1.5 m in length and weighing up to 15 kg. It is covered with brown fur, from which very brightly colored quills protrude; the contrast combination of colour of quills and fur creates a striped zebra-like pattern, which makes this porcupine less noticeable among vegetation. The quills of this animal are longer than those of its Holocene predecessors. This species has short strong tail that serves as a support at tree-climbing and ground digging.
Unlike its relatives, striped tree porcupine is rather ponderous and spends only part of its life in the trees. It often comes down on the ground, searching there for some edible plants, bathes in dust and escapes from enemies (mostly birds of prey). This lifestyle has developed in connection with the fact that this rodent is one of the most southerly species of its family, and lives not in rainforest, where the climate is humid year-round, and the land is often waterlogged, but much farther south, where the climate is drier, with pronounced seasonality, and drought may take place in summer. As a result, the ancestors of this animal had to develop a new way of life.
The food of this animal includes various fruits and lush greens of ground-dwelling plants. In dry season striped tree porcupine eats roots, digging them out from the ground with its powerful claws. It supplements this diet with cockroaches and grubs, founding them in the ground and among the fallen leaves.
In autumn the mating season of this species begins and females call to the males loudly; this call sounds like cat’s meowing. If several males gather around a single female, they will begin to push each other away from the female, until the most powerful and enduring male remains. From that point on, the male porcupine continually keeps near the female. The male mates with the female until the latter is ready to accept the male’s courtship, and it also drives away other males from the female. While the female is pregnant, male stays close to her – this species forms a family to rear the posterity. 1 – 2 well-developed cubs with opened eyes are born at the female three months later. The cubs are cared for by both parents, and they even carry them (sometimes in turns) on their backs. Unlike the side-spined porcupine, this species’ quills grow both on sides and on the middle part of the back. Only the hind part of the back and the base of the tail do not have any quills. The cubs sit on this part of the body of adults, and the adult animal covers them up with its tail, curving it upwards. There are long and moveable quills around this part of the porcupine’s body. In case of danger they lock over the cubs to protect them.
The young of this species grow rapidly, and the next year they become completely independent. They become capable of reproduction at the age of two years.
The maximum life span of striped tree porcupine is up to 20 years, but the most part of animals survives only up to 10-12 years.

Pampas ceratocavia (Ceratocavia colocolo)
Order: Rodents (Rodentia)
Family: Running maras (Cervimaridae)

Habitat: pampas of South America, gallery forests.

Picture by Wovoka

Caviomorph rodents have taken advantage of the biosphere crisis caused by humans. Of course, they had lost some of their species during the anthropogenic crisis, but during the Ice Age they substituted the Pampas deer of South America, occupying the vacated ecological niches. Ceratocavias are somewhat unusual forms among related South American animals. It is a close relative of the deermara (Cervimara), which prefers more humid habitats.
It is a large mammal: body length from 160 to 190 cm, tail 7-8 cm. The height of the animals at the shoulders is up to 110-120 cm; its physique is massive, and the animal looks like a draught horse. Its legs are three-toed, digitigrade, with wide hoof-shaped claws and an elastic tissue pad under the digits. The coloration is brownish-beige, with a noticeable black stripe extending from the shoulder along the flank to the base of the tail; the belly is lighter. On the head of Pampas ceratocavia, a flat wide horn grows; it is formed of hair (like in Holocene rhinoceroses) and gives the beast some resemblance to a unicorn. Male is slightly larger than the female, and his horn is longer and slightly curved. Females and their cubs of the last two years live in herds. Males usually stay alone, joining females only during the breeding season. Skirmishes between them are usually limited to displays – foot stomping, head shaking or, less often, feints; it rarely comes to a fight, and males, as a rule, bite each other’s skin of the shoulders and the scruff of the neck. Females establish hierarchy in the herd in the same way.
Ceratocavia can fight off small predators with its horn, while it prefers to run away from large ones. Females with cubs often organize a collective defense, showing the predator their horns and sharp incisors. Sometimes it happens that the horn of ceratocavia breaks, then the male does not take part in breeding this season. By the next season, the horn grows back, although it requires resources.
This species is an herbivore; it feeds on tough grasses, cereals and leaves, and sometimes eats fruits and berries that fall to the ground. Incisors have a thick layer of dark orange enamel, and molars grow for a significant part of animals’ lives. The nose, elongated and fused with the upper lip into a kind of movable fleshy proboscis, helps the animal to gather food.
The mating season begins at the end of the rain season. At this time, males join the herds of females and protect them from competitors, as well as expel young males over a year old. The males’ clashes become more aggressive at this time, but the males’ fight is limited to horn hooking and “horn wrestling” the with the efforts of neck muscles.
Pregnancy lasts for 8 months. 2-3 cubs are born at the end of a drought or at the beginning of the rainy season. They are well developed: already in the first hour after birth they are able to follow their mother. At the age of 2 weeks, they begin to eat vegetative food, although they feed on milk until about 2 months of age. At the age of 5 months, young animals are completely independent, but they usually stay in the herd for more than a year. The older cubs help take care of the younger ones, lick and speed them when the herd is moving. Males over one year old are driven out by adult males at the beginning of the breeding season. Females often stay in the same herd, but sometimes they move to another herd or try to live on their own. The sexual maturity of females occurs at the age of 1.5 to 2 years, males take part in reproduction since the age of 3 years. Life expectancy is up to 18-20 years, usually less in males.
A related species, the crested ceratocavia (Proceratocavia fuligula), lives in the more arid semi-desert and desert regions of Patagonia. Instead of a horn, it has a tuft of elongated hair on a thick corneous base on its head, and in the males, these hair are almost black, and among them pointed spikes are hidden. It is a more primitive animal, a relic of the early radiation of running caviomorph rodents, which survived due to specialization to extreme living conditions. In places where ranges intersect, males of another species do not arouse the interest of females. It is smaller than its Pampas relative, only 1.2 m long and 1 m tall at the withers. Its wool coloration is lighter, almost white, and the stripes on the sides and legs are much narrower. This animal is able to go without water for a long time, content with the moisture from the grass it eats. Its physique is gracile, with a skin fold hanging down on the neck and chest, which serves to dissipate excess heat. The animal is able to run fast; it defends itself from predators by head blows. The female gives birth to only one cub.

Andean social cuy (Sociocavia andina)
Order: Rodents (Rodentia)
Family: Cavy (Caviidae)

Habitat: South America, Andean Plateau.
In face of the anthropogenic onslaught, some resilient species were capable of surviving. In South America, the guinea pigs (genus Cavia) were one of these survivors. In the Neocene one of their direct descendants is the genus Sociocavia, the social cuy. The members of this genus are highly social animals that form large colonies with burrows, which can be used by other animals. One of the representatives of this genus is the Andean social cuy, a species endemic to the Andean Plateau.
The Andean social cuy have 42 cm of length, with males being slightly heavier than the females. They are generally tan in color, with lighter-colored bellies. However, there could be color variation in their pelt, such as dark fur on their back in black and brown tones. Their forelimbs are strong, with them using it to dig complex tunnels. The tail is very short.
This mammal is a herbivore and feeds on grasses and other herbs. It's diurnal, mainly emerging in the early morning to forage and again in the evening.
During the winter months, these rodents don't hibernate. They continue to leave the burrow to forage, but will enter a state of torpor at night to conserve energy. Torpor is categorized by a drop in metabolism, heart rate and respiration similar to hibernation, but is involuntary and shorter in duration. On average, an Andean social cuy will lose twenty percent of its body weight during the fall and winter seasons when they go through bouts of torpor. As winter progresses, the amount of time spent in torpor increases.
The Andean social cuy is a highly social rodent. They form large colonies with several individuals. Colony size may range from five to thousands of individuals, and may be subdivided into two or more subgroups, based on topographic features. These groups may contain 15–26 family groups. There may also be subgroups, called “wards”, which are separated by a physical barrier. Family groups exist within these wards. Most social cuy family groups are made up of one adult breeding male, two to three adult females and one to two male offspring and one to two female offspring. Females remain in their natal groups for life and are thus the source of stability in the groups. Males leave their natal groups when they mature to find another family group to defend and breed in. Breeding takes place at the beginning of austral spring. The gestation period is about 62 days and females can have five litters in a year. The number of young born averages two and ranges from one to five. The minimum age at which the young adults can breed is thirty days. They have a lifespan of 7 years.

Koriko pexerumen (Koriko insularis)
Order: Rodents (Rodentia)
Family: Cavy (Caviidae)

Habitat: Archipelago of Fernando de Noronha, forests and mountain slopes.

 

Picture by Pavel Volkov

During the Holocene, humans had caused several impacts on the environment. Among their actions was the introduction of exotic species and the places that most suffered with it were the islands. With the disappearance of the human species, these animals remained and some evolved in new species during the Neocene. One of these cases was the koriko pexerumen, the descendant of the population of rock cavy (Kerodon rupestris) that was introduced in the main island of Archipelago of Fernando de Noronha, close to the coast of Eastern South America. Koriko pexerumen is the name in the Xukuru language of Pernambuco for the rock cavy. The koriko pexerumen is endemic to the largest island of the Archipelago of Fernando de Noronha, inhabiting its forests and rocky areas.
The body length of the koriko pexerumen is 95 cm, with a shoulder height of 30 cm. The fur is auburn and pale grey at the underbelly. Its legs are longer than that of their ancestors, giving them the appearance of a small and primitive ungulate. However, it has no hooves, but instead several small nails that remind hooflets. Their feet are adapted to allow them to move through rocky surfaces. The ears are short and the tail is nonexistent. They developed strong incisors, which is used to break hard fruits and shells.
These animals eat fallen fruit, leaves and roots. When feeding, they will stay near each other as a protection from predators. Sometimes they can eat eggs and even shellfish on the seashore.
These animals are diurnal and polygamous, with a male and two females mating and staying together for the rest of their lives. They form groups composed by the male, his females and their offspring. The female gives birth to a litter of 2 to 4 young after a gestation of 4 months. There is no defined mating season, with births occurring many times during the year. The birth usually occurs hidden in bushes and dense vegetation. The young are born well developed and are capable to follow the parents shortly after the birth. The old offspring will help the parents to take care of the young siblings. Both females will help each other to take care of the offspring. They are weaned with 16 weeks and reach sexual maturity with 2 years. Within 4 years, koriko pexerumen leaves the family to form their own. The lifespan of this species is of 19 years.

Rafter coypu (Paracoypu totorae-lacustris)
Order: Rodents (Rodentia)
Family: Coypus (Myocastoridae)

Habitat: Totora Lake, Andes.
Along Pacific coast of South America the extended mountain circuit – Andes – stretches. Conditions of life in this area sharply contrast with an environment of rainforests of Amazonia or savannas of Gran Chaco. The high mountain world is an empire of cold, sharply expressed daily and seasonal change of temperatures and superfluous sunlight. In ice age the high-mountainous climate was dry and very cold. In Neocene the climate began more humid; the increase of amount of rains had caused occurrence of large lake at Altiplano plateau. In human epoch at this plateau there were some lakes among which Titicaca lake was the most known one. Gradually all lakes of Altiplano had merged together, and at the plateau the huge Totora Lake appeared.
Coypu reached significant evolutionary success in South America. Among descendants of this animal there is a unique group of mammals – algocetids, huge aquatic animals. It is the most deviated and specialized branch of rodents making the separate order. Other descendants of coypus are less specialized, but it does not prevent them to prosper in nearwater biotops. In South America they are analogues of beaver and muskrat, and settle down to the cold south of continent. One descendants of coypu has developed high mountains, and its population lives at Totora Lake. It is rafter coypu, animal leading unusual way of life and differing in advanced building behaviour.
Rafter coypu is large species of aquatic rodents keeping anatomic features of the ancestor. The velvety fur with small amount of guard hair serves to this species as fine thermoisolation in very cold water of the lake. In fur colouring significant polymorphism is observed – among animals there are individuals from grey and straw-coloured up to brown and black ones. Rafter coypu carefully looks after fur, and combs it by claws for a long time. Forepaws at this animal have mobile fingers and are adapted to manipulation with small objects.
Ears of this mammal are short, and eyes are small. This animal receives a significant part of information about the world around with the help of smell sense. On a muzzle of rafter coypu numerous whiskers grow, helping to orientate in darkness.
Main moving organ of this animal at the swimming is its tail. It is wide, rounded and looks like cut off at the back edge. Tail is covered with hairless tight skin and contains the advanced fat layer; therefore warm does not leave an organism of animal through naked skin of tail. In water rafter coypu swims with the help of tail, having pressed paws to body and making wavy bends by backbone. During feeding at shoaliness animal swims slowly, with the help of webby hind legs. Rafter coypu is able to dive to the depth up to 10 meters and stays under water till about 5 minutes. But it prefers to use this skill only in case of extreme danger, because it feeds in coastal shallow zone.
This species is strictly herbivorous animal, eating rhizomes of totora reed (in language of Indians of Andes it is the name of the reed known in human epoch, hence the name of lake) and tubers of water plants. Eating rafter coypu simultaneously receives building material for its shelters. This animal digs out sprouts of reed with the help of strong incisors and claws of forepaws. At the dug out plants rafter coypu bites off and eats rhizome and the bottom part of stalks, and pulls a bunch of poorly nutritious stalks to original shelter in which it spends night.
These animals build rafts and huts on them of reed. To construct a raft, rafter coypu bites off stalks and branches of coastal plants, drags them to common heap floating on surface of water, and constantly renews the construction. As a rule, some animals begin simultaneously construction of raft. They constantly drag the cut off rods and stalks of reed on rafts, and trample them down, moving on rafts. On such raft the hut is placed, in which the pair of adult animals and their posterity lives. Hut has the hemispherical shape, reaches one meter height and has thick friable walls. The entrance opens sideways; if the raft is great enough, near to an entrance animals specially make an outlet to the water and clear it regularly, dragging off from it the rests of plants.
Small rafts, constructed by separate family groups, may gather to form big floating islands and give a haven for other creatures. When some rafts are linked together, their inhabitants do not try to uncouple them – rafter coypus are sociable enough and between them there are no serious conflicts. They simply throw more reed stalks on edges of linked rafts and form unite large raft. Running on it, animals trample down its surface, and the rests of their food serve as a building material. Such rafts may exist for many years, constantly being renewed. The part of reed rhizomes not eaten by rafter coypus sprouts in thickness of rotten stalks, and additionally strengthens the construction. Sprouts of reed make the way through surface of raft, and serve as good top dressing for these animals. In the middle of raft animals eat sprouts completely, and on edges the bitten stalks of totora reed plentifully branch, forming green fringe.
The pair of adult animals rises within summer one litter – up to five cubs. The young growth of these animals is born with open eyes and covered with rich wool. The female cares of posterity within two months, and at this time male is engaged in repair and construction of raft alone. Young animals leave dwelling already at week age, and monthly cubs swim perfectly. They live in common with parents within the first winter. At this time young females reach sexual maturity, and males become large enough (they mature later). Females leave parental raft and settle on rafts of other males, forming pairs with them. Young males are banished by their own father, and they start to build their own rafts or occupy and renew empty huts.

The idea about existence of this species was proposed by Momus, the forum member.

Chilean algocetus (Algocetus chiliensis)
Order: Algocetiforms, “algae whales” (Algocetiformes)
Family: Algocetids (Algocetidae)

Habitat: Pacific coast of South America.

Human activity and climatic changes at the boundary of Holocene and Neocene had caused fast disappearance of plenty of species of sea animals. Sirens had become extinct irrevocably in that epoch, and cetaceans and pinnipeds are present as rare relic forms in Neocene. But after mankind disappearance and stabilization of climatic conditions life began to restore the lost positions and to form new ecosystems again. Seas of northern hemisphere in Neocene are occupied by birds – gannetwhales and flightless loons. These animals dominate in Atlantic and Arctic oceans. In Pacific Ocean large flightless hatchetbills (a kind of auks) replace them, and at the Asian coast algal geese and penguin duck also live. But in cold and temperate waters of southern hemisphere birds are presented only by flightless penguigulls of several species. These birds eat animals, and mammals came to the place of herbivorous marine animals.
Sea mammals of southern hemisphere descend from South America. They are descendants of coypu (Myocastor coypus) widely settled in a moderate and subtropical zone of continent. Coypu had successfully passed the period of anthropogenous pressure, and even had widely settled due to human activity – it was domesticated.
Sea mammals of Neocene are herbivores. In early Neocene when sirens – completely aquatic herbivorous mammal – had disappeared, evolution of coypu had gone especially roughly. Till some millions years descendants of coypu had passed approximately the same way, than cetaceans in early Eocene epoch did – from small semiaquatic creatures up to completely aquatic large mammals lost connection with land.
Descendants of coypu form the separate order of mammals – Algocetiformes, “algae whales”. In their anatomy features of rodents and features of obligatory aquatic mammals (whales and sirens) developed convergently are combined. Algocetids are large animals; smallest of them reach the length of 3 meters, and at coast of Antarctica and at the south of South America the giant about 7 meters long, weighting over 6 tons, lives. They resemble sirens externally a little; it is the result of similar habit of life.
The muzzle of algocetes differs in advanced, mobile and partly doubled upper lip on which bottom side lines of corneous combs grow. With the help of such lip the animal easily scrapes off from stones seaweed which it eats. The bottom jaw differs in massiveness, and incisors in it are very large and wide. Such incisors help to tear off from stones not only seaweed, but also sedentary animals – mollusks and barnacles.
Nostrils of algocetids are shifted to the top part of head – such structure permits the animal to breathe, having put out from water only small part of head. Large individuals emerge for some minutes, and then can hold the breath till half an hour. Cubs emerge to breathe much more often.
Though algocetids are completely marine animals, not capable to leave on land, they swim not so well. These animals prefer to move in shallow water similarly to Steller’s sea cow – making steps on bottom by well advanced mobile forward extremities. On them two large claws (on II and III fingers), assisting to cling to bottom, are present. IV and V fingers are reduced, lack of mobility, and only support a plane of flipper. The thick layer of fat serves not only thermoisolation, but also a fine float, reducing loading to extremities of animal. Rear legs of algocetids had reduced completely, and on the tip of tail the wide rounded fin is developed. Algocetes are sluggish swimmers, and during storm they prefer to hide in rich thickets of seaweed which soften force of waves.
Eyes at algocetes are small, but sight is rather quite good. Animals prefer to live in places with transparent water, supporting visual contact to each other. They also can produce sounds with the help of air bladders in nasal ducts. External auditory meatus at algocetids is not closed, but an eardrum is thick. Bones of internal ear are isolated from skull by special fatty tissue, like at cetaceans. The upper lip is covered with thick whiskers (hair thickness is up to 3 mm), which help to search for food in muddy water.
Algocetes keep in families including a breeding pair or the male and two females, and their posterity of last two – three generations. At the largest species living near Falkland Islands and in Antarctic Region, herds of several tens of individuals including some breeding groups are formed. Pregnancy lasts about 16 months at large species and about 11 months at smaller ones. As a rule, the female at all algocetid species gives rise to two well advanced cubs. Only at the largest species there is only one cub. Cubs are born covered with thin fur which drops out till first days of life. At the delivery the female is surrounded by neighbours push the cub out to the surface of water. When the cub starts to move, they leave it, and only its own mother cares of it. But if necessary, females of algocetuses protect young growth against large predatory fishes together. Nipples of the female are located on sides of body, approximately at the level of pelvic girdle hided in thickness of muscles. To make more convenient to cub to be fed, the female lies down on the side, and the cub sucks milk, having put nostrils out to the surface of water, and breathing. Cubs suckle milk about half-year, but already from bi-monthly age start to eat food of adult animals.
In Neocenic fauna algocetids are presented by one family and four species.
Chilean algocetus lives at Pacific coast of South America, and the separate population with doubtful specific status inhabits waters of Galapagos Islands. The length of this species reaches 4 – 4,5 meters. This species lives in coastal zone, preferring areas of coast protected from storm waves by barrier of small islands. Its distribution is closely connected to cold current flowing from coast of Antarctica. These animals eat brown and green macroalgae. Due to their fast growth animals lead almost settled way of life, moving within the borders of the territory to some kilometers. This species willingly swims to lower reaches of short rapid rivers flowing down from Andes to Pacific Ocean. In such way these animals escape of ectoparasites perishing in fresh water.

Patagonian coypocetus (Coypocetus patagonicus) inhabits rivers of Atlantic coast of South America. It is the smallest species of algocetes – the length of adult individuals hardly exceeds 3 meters. It constantly lives in fresh water and eats aquatic flowering plants. At this species there are rather large claws – with their help the animal digs out rhizomes of water plants and protects itself from enemies. Its forepaws are mobile; with their help animal can bring food to mouth. Digging out silt and eating water plants, these animals interfere with bogging of the rivers. To wintering these animals migrate from upper streams and move down to the mouth of the river, forming there big congestions destroying water vegetation along many kilometers of riverbanks. At the lack of forage they may swim for the short time to coastal sea waters.

Closely related to the previous species coastal coypocetus (Coypocetus littoralis) has wide area: it lives along the Atlantic coast of South America. This animal does not meet in fresh water at all. Its length is about 4 meters. Coastal coypocetus is rather heat-loving, and does not settle far to the south. But it also does not love very warm water; therefore the northern border of its area does not reach mouths of Amazon and Hyppolite rivers.
All species of algocetuses described above live in shallow waters and do not swim far from coast. Therefore Falkland paralgocetus (Paralgocetus falklandicus), the largest species of algocetes, looks the exception among them. It is the true giant among algocetes, reaching the length of 7 meters. It lives at the coast of Falkland Islands and rather frequently leaves in open ocean. This animal frequently feeds in congestions of floating brown seaweed in southern part of Atlantic. It differs from other species of algocetes in very big fat incrustation expanding on forward part of head between nostrils and upper lip. This pillow is used as ram during intraspecific duels. At this species there are small dulled claws on forward fins, and sometimes the claw on II finger is completely reduced. A tail fin of Falkland paralgocetus is triangular-shaped, but it is not such wide, as at whales.

Due to the size and thick layer of fat (up to 15 cm) it is the most cold-resistant species of algocetids, reached the certain success in evolution. Rather recently (according the geological measures) the small population of this species migrated to coast of Antarctica, and later descendants of first settlers settled generally coasts of continent. The Antarctic representatives of this species became more omnivorous, and at polar night marine invertebrates frequently make up their food.

Caribbean algocetus (Xenalgocetus diodon)
Order: Algocetuses (Algocetiformes)
Family: Algocetuses (Algocetidae)

Habitat: Caribbean Sea.

Picture by Carlos Pizcueta (Electreel)

Herbivorous sea mammals in human epoch were presented by sirenian order – not numerous group of sluggish aquatic mammals. These animals bred slowly and differed in poor ingenuity. It made them very vulnerable for hunting, and their number began to reduce even in early historical time. Despite of strict protection, residual populations of these animals had not gone through human epoch. In Neocene various groups of vertebrates competed for a role of sea herbivores. In Tanganyika passage algal turtles (Thalassotestudo algophaga) live, but they did not manage to become dominant herbivores of seas – their distribution is limited only to warm waters of passage. Descendants of South American rodent coypu (Myocastor coypus) have achieved the much greater success. At coast of South America the representatives of new group of mammals descended from them very fast to evolutionary measures; these ones are algocetuses, herbivorous animals permanently living in sea. The majority of algocetuses does not cross equators and is settled only in coastal waters of South America and Antarctica. Only one species managed to step to the north, to Caribbean Sea. Thickets of sea spinach (Thalassolatucca crystallophylla), floating aquatic plant, are the basic source of food for Caribbean algocetus, heat-loving species of herbivorous water mammals.
Caribbean algocetus is a second-largest species in order after Falkland paralgocetus. The body length of adult individual reaches 5 – 6 meters. Layer of blubber at this species is thin – it is a consequence of life in tropics. However the blubber layer is necessary for it serving as an adaptation facilitating swimming. Caribbean algocetus spends a significant part of life at the surface of water. At this species the extra adaptations were developed, allowing the improving of heat radiation: skin is covered with the numerous cross wrinkles increasing its surface. Tail fin is wide with rounded flukes – it is not only swimming organ, but also the adaptation for heat emitting. Caribbean algocetus swims slowly and dives only to depth of about 20 – 30 meters only in case of extreme danger, for example, in storm. At its way of life speed and ability to dive deeply become almost excessive, because its forage is always on surface of water.
Rear limbs of this animal had disappeared completely –only rudiments of sacrum and hip remained from them. But front flippers of this species are very mobile – they are rather long and can bring food to mouth. Front limbs keep mobility in elbows and even prehensile function is kept partly at them. The second and third fingers of forward limb are covered with the common skin cover, are separated from the fourth and fifth fingers by small interval and can move independently of them. Due to this feature the limb capable to grasp food is formed. On second and third fingers large claws are advanced.
Caribbean algocetus eats mostly sea spinach – floating species of aquatic plants living on surface of Caribbean Sea. This plant lives in stable conditions and always gives plentiful growth, therefore groups of these animals are always provided with habitual forage. Caribbean algocetus, however, does not leave far in sea – it is possible to find only separate males at great distance from the coast. The basic population prefers to be fed in thickets of sea spinach above depths up to 100 meters. This animal may be seen frequently in shallow waters; it swims there for thickets of sea spinach carried by wind, and also for aquatic plants growing on shoaliness. In silent weather this animal occasionally comes to edges of mangrove forests and in high inflow browses leaves of mangrove trees. Feeding on branches of mangrove trees, Caribbean algocetus swims in shallow water, lies sideways and drags branches of mangrove trees to mouth by forelimb. In outflow this animal tries to swim to deeper places. Occasionally the careless animal can get in a trap among mangrove trees: when passages become too shallow, animal stays on shoaliness and may die from heatstroke or choke under weight of its own body.
Soft vegetative food had resulted in significant changes of dental system of this species. Molars are lack completely, and they are replaced with corneous plates with ribbed chewing surface. Incisors in top jaw had turned to tusks similar to tusks of walrus or dugong, but shorter, rather than their ones. They are used in tournament fights of males. Female tusks are smaller. In lower jaw incisors are reduced completely.
Once in two years female gives rise to one large cub. Once in ten – fifteen cases of birth twins may be born. The one and a half meters long cub quickly grows, eating fat milk. Till two months of life it doubles its initial weight and gradually passes to feeding on plants though it is fed with milk almost up to one-year-old age. At four-year-old age the young animal is ready for breeding.
Caribbean algocetus lives in herds under the leadership of large female. Usually such herd totals up to 20 – 30 adult females and their posterity of the first years of life. Young males stay in herd up to their sexual maturity. Adult males form large barchelor herds which break up in breeding season. The female ready to pairing emits with urine the substance which taste helps males to find her out. In courtship season male behaves aggressively relatively to contenders. Battling for the female, males snap each other’s flippers and tail flukes. Battling with the help of tusks, they strike each other lateral impacts by head. Tusk points are used only for protection against predatory fishes.
Life expectancy of Caribbean algocetus reaches 35 – 40 years. Sharks are main enemies of these animals, but these mammals are more often suffer from the parasitic invertebrates boring into skin. Animals escape from them, coming into fresh water where parasites perish. With the same purpose during the inflow algocetuses scratch against roots and trunks of mangrove trees.
