Speculative Evolution Wiki

After Man: A Zoology of the Future is the first book of speculative zoology/evolution written by Dougal Dixon Published in 1981, it exposes though different descriptions and illustrations the inhabitants of the earth 50 million years in the future after the extinction of humanity and much of the Holocene megafauna.

Geography of the future

Earth Map in 50 million years in the future.

Dixon assumes that Europe and Africa would eventually fuse, closing up the Mediterranean Sea. Asia and North America would collide and close up the Bering Strait. South America would split off from Central America. Australia would collide with southern Asia, uplifting a mountain range. Finally, parts of eastern Africa would split off to form a new island which he called Lemuria. Other volcanic islands have been added, such as the Pacaus Archipelago and Batavia.

Animals of After Man: A Zoology of the Future

Anchorwhip, Flagellanguis viridis, a venomous rainforest tree snake that uses an anchor-like tail to snatch birds and small mammals.
Angler Heron, a heron that creates a fish pond and baits it to attract fish.
Bardelot, a giant bear-like predatory rat; the female has saber teeth protected by bony pouches when her mouth is closed.
Beaver, a surviving rodent species. Unlike our beaver, this new beaver has its legs fused with its tail, like current day pinnipeds.
Bootie Bird, a large hawk-like descendant of crows.
Broadbeak, a giant predatory songbird.
Chirit, an inchworm-like rodent descended from squirrels.
Chiselhead, an inchworm-like rodent with massive incisors for chiseling through live trees.
Chuckaboo, Thylapithecus rufus, a monkey-like marsupial.
Clatta, a sloth-like prosimian primate with an armored tail as protection against predators.
Cleft-Back Antelope, a primitive-looking antelope from Lemuria. It has two ridges on its back, leaving a furrow along its spine. It is covered with warts that attract flies - and a species of tickbird. This tick bird feasts on these flies and it makes its nest in the furrow of the antelope's back.
Common Pine Chuck, a bird in which the two sexes look like different species. Males are red with massive beaks for eating pine cones. The female is green with a slender beak for snatching insects and carrion.
Desert Leaper, a large hopping rodent and the largest desert mammal on Earth. It can store so much fat in its body that it can lose half its body weight without any problems.
Desert Shark, a sparsely-haired, sausage-shaped predatory descendant of shrew-like animals.
Desert Spickle, a nectar-eating spiny mammal that sips from desert flowers.
Distarterops, Scinderedens solungulus, a marine rat that looks like a cross between a beaver and a walrus with a claw on only one of its limbs.
Falanx, a wolf-like predatory rat.
Fatsnake, a venomous viper-like snake with an enlarged tail, related to cobras.
Fin Lizard, a two-legged lizard with enlarged skin flaps on its neck and tail, increasing its surface area. It can run 2.5 miles (4.1 kilometers) per hour.
Flightless Auk, Nataralces maritimus, a penguin-like descendant of auks. It forms a chain of different linages that breed with one another (known as a cline). However, the races of auks at the ends of the chain are so different that they cannot interbreed.
Flightless Guineafowl, an ostrich-like Guinea fowl with a large throat sac.
Flooer, Florifacies mirabila, a flightless bat with a nose and ears that imitate the designs of native flowers.
Flower-Faced Potoo, a strange descendant of South American potoos that spends most of its time on the ground. Its wide mouth imitates the patterns of the native flowers, attracting insects. These potoos migrate seasonally because the flowers it imitates do not come until after rainstorms.
Flunkey, Alesimia lapsus, a gliding monkey.
Gandimot, Bustivapus septentreonalis, a predatory bird that is descended from magpies (although it resembles a skua and lays eggs in the nests of other birds).
Ghole, Pallidogale nudicollum, a bone-eating scavenging mammal.
Giantala, a giant ground sloth-like kangaroo.
Gigantelope, a massive, bulky descendant of antelopes and the largest listed land animal in the book. It comes in two types: a virtually hairless tropical species and a slightly smaller woolly polar species. Both have massive plow-like horns used for digging up roots. The rundihorn is a rhinoceros-like gigantelope but instead of plow-like horns, it has four cone-shaped horns. There is also the long necked gigantelope, which has, of course, a long neck and small horns.
Groath, a goat-like relative of hornheads. Males have plate-like horns and females have pyramid-shaped horns. These hoofed mammals live in herds.
Grobbit, a hoofed rodent with flexible hands for pulling down branches. Much of its body length is tail, one meter of it.
Gurrath, Oncherpestes fodrhami, a jaguar-like descendant of mongooses. It inhabits South America after it fused with the Caribbean, where mongooses were introduced 50 million years ago.
Hawkbower, Dimorphoptilornis iniquitus, a predatory bowerbird of Australia. The male has a curved flesh-tearing beak and skewers its victim to a thorn to attract flies. A mated female captures the flies and feeds them to the male to ensure his attention. The fly larvae in the flesh of the victim are fed to the chicks.
Hiri-Hiri, Carnophilius ophicaudatus, a predatory marsupial with a snake-like tail for strangling its prey.
Hornhead, a massive moose-like relative of antelopes. It comes in three types. The common hornhead looks like a cross between a moose and an antelope with a larger lower jaw. The helmeted hornhead has axe-shaped horns. The water hornhead has branched horns and a spade-shaped mouth for plucking water plants.
Horrane, a lion-like primate that hunts massive gigantelopes. It uses its sharp teeth and curved claws to slaughter its prey. However it eats only the soft flesh of a carcass.
Janiset, a weasel-like predatory rat.
Khiffah, an ape-like primate that lives in huge groups.
Khilla, a coyote-like descendant of shrews.
Kriskin, a common predatory bird of desert.
Leaping Devil, a round short-faced insectivorous mammal with a long tail and long legs. It hunts desert reptiles and small mammals, like the spitting featherfoot

Lesser Ptarmigan, a small game bird that coexists with small meachings.
Long-Armed Ziddah, a slender-legged primate.
Long-Necked Yippa, a long-necked descendant of antelope from Lemuria. It uses its long neck for reaching into tropical forest trees.
Long-Legged Quail, a large predatory descendant of quails.
Long-Necked Dipper, an aquatic bird that flies when a juvenile, but becomes flightless as an adult. It spends much of its time underwater.
Lutie, a nocturnal mouse-like descendant of rabbits. However it is not a common animal due to competition with surviving mice, rats, and voles.
Matriarch Tinamou, a South American ground-dwelling bird. The female is a large ground-dwelling bird. The male is several times smaller than the female and rides on her back, sucking her blood and mating.
Meaching, small lemming-like rodents that create intricate tunnel systems. They are food for polar ravenes, bootie birds, and gandimots. Their fortresses are made of dead vegetation because they can not tunnel through permafrost.
Mud-Gulper, a giant aquatic rodent that looks like manatee with a hippopotamus's head.
Nightglider, a predatory South American mammal related to weasels. It glides with folds of skin stretched between its arms, legs, and tail. Its chest is covered with quills for skewering prey. Its fur is colored to match the patterns of certain trees.
Night Stalker, Manambulus perhorridus, a flightless bat from Batavia. It supports its body on its arms, which are strong since they were once used for flight. It uses its legs for clutching its prey and slashing. The night stalker is blind and uses sonar to locate its prey. It hunts in packs, and is about 5 ft. (1.5 m.) tall. Similar creatures to the Night Stalker appeared in Primeval.
Oakleaf Toad, Grima frondiforme, a toad covered in flaps of skin that resemble an oakleaf. During most of its life, the toad is naturally brown. But when a parasitic fluke within the toad matures, it turns green, revealing it to predators like the predatory rats. The oakleaf toad is a predator itself - hunting small animals and using its worm-like tongue as a lure.
Pacauan Bird Snake, a snake native to the Pacaus Archipelago. It hunts whistlers and is one of the few active predators on these islands.
Pacauan Whistler, Insulornis spp. a group of birds that colonized the islands of Pacaus. They are descended from golden whistlers and have become highly specialized types. Some species eat nuts and have massive rounded beaks. Some have pointed bills for extracting insects from beneath the bark. Some even have hooked beaks for tearing flesh.
Pacaus Coral Fish, a fish found in the Pacaus coral reefs. Used as an example of a fish for the time period of 50 million years in the future.
Pamthret, a puma-like descendant of weasels that hunt in packs. It inhabits conifer forests: one of the few places that carnivorous rats have yet to reach.
Parashrew, a shrew-like mammal with an umbrella-like tail used like a parachute.
Pfrit, an insectivorous mammal with a hollow lance-like mouth for eating mosquito larvae. It is the smallest mammal known, growing only two inches excluding its tail. It is so light it can even walk on water.
Pilofile, a bird species that adopts two distinct lifestyles. During the summer, this bird has a short beak surrounded by hair-like structures that work like a funnel for scooping up insects. During winter, it sheds that beak and grows a longer beak for probing.
Porpin, a dolphin-like descendant of penguins.
Posset, a marsupial pig that inhabits the forest floor of the Australian rainforests.
Purrip Bat, a bat in which the eyes have vanished and its ears shifted to the front of the head, advancing its echolocation system.
Pytheron, a predatory seal-like rat. It preys on flightless auks and fish, and is in turn preyed upon by the male of another giant predator rat, the bardelot (the female bardelot, with her saber teeth, preys on woolly gigantelopes).
Rabbuck, a giant hoofed deer-like descendant of rabbits. It comes in two types: deer-like runners and primitive rabbit-like hoppers. Some tropical species like the strank and the watoo filled the niches of past herbivorous mammals, such as zebras and giraffes. The picktooth is the most bizarre rabbuck, sporting two tusk-like teeth and a spur on both forelegs.
Raboon, Carnopapio spp., carnivorous descendants of baboons. They evolved a gait like those of predatory dinosaurs. Different types inhabit the savannas, from small active predators six feet tall to monstrous scavengers over eight feet tall.
Rapide, a cheetah-like predatory rat.
Ravene, a fox-like predatory rat. This type comes in two forms: a woodland species and a slightly larger polar species.
Reedstilt, a large fish-eating mammal about 3.25 ft (1 m) high at the shoulders and 132.25 pounds (60 kilograms) in weight. It has an elongated neck, sharp teeth, and slender hair-covered legs.
Rootsucker, a burrowing rodent with a shell and a face plate made of compressed keratin (the same material that forms our hair and fingernails, for instance). It burrows underground to feed on the roots of desert plants.
Ruffle, a mountain-dwelling descendant of rabbits. It has short ears, long fur-covered legs, and short teeth for chewing moss.
Sand Flapjack, a flat-tailed rodent that uses its tail to cool its body in its desert habitat. They build condensation traps, placing a pile of stones and twigs atop a burrow. It collects dew and drips into a trap beneath.
Shalloth, Arboverspertilio apteryx, a sloth-like flightless bat from Batavia. It is omnivorous and sometimes kills small animals with its sharp thumb claw. Once wings, its hand has a single separate digit and its other fingers have fused together. It spends much of its life hanging upside-down.
Shrock, a burrowing insectivorous mammal that resembles a badger. It is similar in size, about 2 feet (61 centimeters) in overall length.
Shurrack, a descendant of weasels that resembles a long-legged snow leopard. It hunts groaths in packs.
Skern, a flightless seal-like seabird.
Slobber, Reteostium cortepellium, a marsupial sloth that attracts insects with drips of mucus.
Snorke, a long-faced grazing antelope from Lemuria.
Spine-Tailed Squirrel, a striped squirrel with quills lining its tail. When threatened, it raises the tail and shields its body, spines outstretched.
Spitting Featherfoot, a hopping desert rodent that eats toxic plants. To eject the toxins, the featherfoot spits at attackers.
Strick, a kangaroo-like rodent that runs on two legs. It evolved massive ears for hearing over the tall grass. It lives in South America.
Striger, a monkey-like descendant of the last cats. It evolved to hunt fast arboreal animals, like monkeys and thus many tree wildlife battled to combat this new predator.
Surfbat, Remala madipella, a seal-like bat from Batavia. The surfbat has a pointed snout, prominent eyes, and flippers made from degraded wings. In many respects, it is the mammalian equivalent of the penguin.
Swimming Anteater, Myrmevenarius amphibius, an aquatic anteater.
Swimming Monkey, an aquatic monkey that hunts fish.
Shink, which is seen being parasitised by trovamps.
Tapimus, Tapimus maximus, a tusked rodent from South America, about 2.25 feet (69 centimeters) high at the shoulder.
Termite Burrower, a burrowing bird species. Unlike the spink from the film The Future Is Wild, it uses its feet to burrow and has lost its wings. It uses its sticky bristle-tipped tongue for gathering termites.
Terratail, a rodent and one of the few mammals that inhabit the Pacaus Archipelago. It avoids being hunted by predatory whistlers by evolving a patterned tail that imitates the Pacuas Bird Snake. By thrusting its tail forward and hissing behind a branch, it scares off most of its predators.
Testadon, an insectivorous mammal with a hinged shell that can form an impenetrable ball.
Toothed Kingfisher, a swimming descendant of kingfishers.This bird has a beak that has small points, thus replacing the teeth of the Mesozoic birds.
Tree Drummer, an enigmatic arboreal mammal with chisel-like teeth, a barbed proboscis, and feet covered in fine fur. These hairs sense the movement of grubs beneath the wood. Then the tree drummer bores a hole through the wood and spears the grub with its proboscis.
Tree Duck, an arboreal duck that rarely swims.
Tree Goose, an arboreal goose with only two toes, used for wrapping around a branch.
Trevel, a monkey-like rodent with slender fingers and a prehensile tail. It uses both to reach pine cones out of the reach for animals its size. It is descended from harvest mice.
Trovamp, Hirudatherium saltans, a parasitic mammal that clings to its host with barb-like fangs and claws.
Truteal, a blind rabbit-like mammal descended from shrews with a bird-like beak made from outstretched incisors. It has large ears for detecting worms and it uses its teeth for grabbing its prey.
Turmi, an anteater-like pig.
Tusked Mole, a mole with a pair of tusks that aid in digging and catching insects.
Unnamed fish being chased by a swimming monkey.
An Unknown Creature, apparently a large animal that is suggested to live in the far future. (After 50 million years later.)
Valuphant, the largest ungulate on the island of Lemuria, growing 16.375 feet (5 meters) long. It has a tall ridge over its spine for monitoring body temperature and two horns a meter each. It plays a vital role in its native Lemurian ecology like the elephants of the past, such as distributing the soil while feeding to simulate new plant growth.
Vortex, Balenornis vivipera, a whale-like descendant of penguins. Its massive beak is laced with slits for sifting ocean water for plankton.
Wakka, a South American rodent with two legs and no forelimbs that can see over the long grass.
