Metazoica

 The family Chirosapidae is a highly varied family of lemurs. These are the original lemurs that evolved in the Metazoic. They branched off the modern family Galagidae, of which several species in the Metazoic family retain many characteristics. Their homeland is Africa, and more than 50% of the animals in this family still live there in the Metazoic. Most species are tree dwellers, as would be expected of any lemurs. But several species can inhabit ground levels, and even the ocean. They range in size from the tiny dwarf bushbabies ( Galaguella ) to the 20-foot long Chirosapus robustus . But most species are small and light animals. These animals differ from other lemur families, like the closely-related Pileatidae, by a lack of a sagittal crest, and the forelegs are considerably shorter than the rear legs. Most species in this family are diurnal, with the exception of the Sciurocheirinae, the bushbabies. The majority of the bushbabies are nocturnal. This is one trait they carried...

 This is the largest family of pentadactyls. The family Pileatidae is characterized by the legs and arms all being of the same length, a throat pouch, and usually a horse-like mane. This is a highly varied group of lemurs, they range in size from the very tiny genus Sylpha , which is small enough to build their nests in bamboo stalks, to the genus Toru , which stands as tall as a 3-storey building. The diet also greatly varies. The majority of species feed on leaves, grass, fruits, nuts, berries, occasionally insects and small vertebrates. But one group, the Tyrannocypikinae, are almost completely carnivorous, feeding on large mammals, birds and bats. They feed on meat far more than any other pentadactyls, whether they kill the prey themselves, or scavenge. This group of lemurs somewhat parallels the modern family Lemuridae, in that all their limbs are the same length, and the tail of most species is long and held upward. Rather like a cat's tail. The tail may be tipped by a large ...

 I realize this is late. I was so excited going to the bird expo last weekend, this blog slipped my mind. But I am back now. The family Pinnepitheciidae is the earliest branch of completely aquatic pentadactyls. They arose from the family Promonsamiidae, particularly from the genus Hydrabilis , which is also the precursor of Thaladapis . These sea monkeys differ from the Delphinadapids by having larger, more rounded flippers, and a relatively shorter, spade-shaped tail. But like all other aquatic pentadactyls, these animals are just as agile in the water as other lemurs are in the trees. But unlike such aquatic lemurs as the Promonsamiids, these lemurs are almost entirely aquatic, only coming ashore on the beach to sleep and rear young. They breed in colonies, like sea lions. Their movement is not like that of sea lions, but more like sea turtles. They push themselves over the sand using all four flippers. The fur is short, but thick, like a bear's coat. All species are mostly acti...
