platypus (Ornithorhynchidae). They still lay eggs and the young eat from pores in the
mother's belly. Metazoic platypus still live in or near water, and the larger species have even
learned to build nests out of mud.
Marsupials - During the Metazoic, the remaining marsupials include only phalangers,
kangaroos and dasyures. Then there are the opossums that inhabit North and South
America. The kangaroos are quick, limber animals. There are only a few species of
dasyures. Phalangers and opossums however are rather slow-moving animals. In the
Metazoic, all marsupials have well-developed pouches to carry their young in.
Insectivores - This group includes the moles and shrews. Most insectivores are small,
with the exception of the Armigeridae, which is a family of large, armored, ant-eating
insectivores that derived from shrews. The teeth of these animals are small and pointed
with tough enamel, the jaws are powerful.
Megachiropters - Also known as the Pteropods in the Metazoic. There are 3 families of
these special kind of bats. These bats are so unlike others that they deserve to have their
own order. Unlike the Microchiropters, these bats have developed powerful legs for
perching, like birds. The wing surface is also reduced greatly in these bats, and they have
no webbing on the legs. They are also much more intelligent than other bats. The wings
have less webbing, but these bats manage to stay airborne by having lighter bone
structure, and small hairs specially arranged on the surface of the wings.
Microchiropters - These are the small bats that hunt by radar. During the Metazoic,
these bats have for the most part lost their eyes, and the ears have fused together at the
front of the head. Unlike the Megachiropters, these bats still have to hang upside down,
and have a larger wing surface. They are also less intelligent than the Megachiropters.
Pentadactyls - These are the Metazoic's monkeys and lemurs. Formerly known as the
primates, during the Metazoic they changed. While most smaller species still remain
tree-dwellers and branch leapers, there are also some large pentadactyls that never
climb trees, but rather remain at ground level, and even a few species that have taken to
water. But they all still have opposable hands and fingers. Most species have 5 fingers
and toes, hence the group name, whereas all other Metazoic mammals only have 4 or
Pseudosims - A branch off the pentadactyls, these are large, bipedal, mostly
ground-dwelling animals that browse leaves or feed on grass. The necks are long, and
the head is camel-like, the ears are small and round. The tail is long and
counterbalances the head and neck.
Rodents - Still the largest group in the Metazoic, these are mammals that have 2 long
incisors in front for gnawing grass, leaves and even wood. Many are small species, but
there are also some rather large rodents in the Metazoic. Some have even become
Carnivores - During the Metazoic, the most successful carnivores are the dogs,
mongooses and weasels. Carnivores are the only mammals that have well-developed
carnissal teeth, which are specialized molars. The largest carnivores in the Metazoic
are larger than any during the Cenozoic.
Pinnipeds - There is only one family during the Metazoic that makes up this group,
they are the sea-bears, which are derived from polar bears. The feet have become
highly efficient flippers that propel these animals through the oceans. They are also
less effective for walking on land.
Trelatebrates - These are exclusively Metazoic mammals. There are several
families, including the Therapeds and deinognathids. They branched off from the
elephant shrews. They are distinguished by having soft hands with fingers, and the
feet are hooves. In some families, all the feet are hooved. Therapeds have hind feet
rather like a camel's. Many are bipedal, but there are some quadrupeds. The diet
varies. Some, like the deinognathids, are very efficient predators. Therapeds will eat
anything. Most other species are vegetarians.
Artiodactyls - The only true hoofstock still existing in the Metazoic. The only
successful artiodactyls in the Metazoic include the antelope, hogs, camels and deer.
In most species, the feet are completely hooved, except in the camels, which have
soft feet. Many have long necks and most are vegetarian.
Pleuropters - Another exclusively Metazoic group. These creatures evolved off the
bushbabies. They are unique among mammals in that the ribs have bony, fleshy
extensions that create something to the effect of "wings", which is actually a special
gliding apparatus. This allows these small mammals to glide over great distances. By
shifting the wings, these animals can even steer themselves slightly in mid-air. They
are basically fruit and leaf eaters, but sometimes feed on insects and grubs.
