Fauna of the Paleocene and Eocene (65.5-34 million years ago)
Wildlife in the Paleocene and Eocene epochs (65.5-34 million years ago) was primarily represented by mammals and birds. Among mammals, the dominant herbivorous forms ranged from the rabbit to the hippo. Typical examples of the time were Dinoceratas, the leading representative was the Uintatherium which reached 4.5 m in length with a height of 2.5 m. In addition there were the widely spread heavy water rhinoceroses Aminodontidae up to 4 m, the hornless rhinoceros Hyrakodontidae, close relatives of the elephants (but the size of the dog) Pantolambdy and Moeritherium, the ancestors of modern horses (the size of a fox) - Hyracotherium and Orohippus. Also in the Paleocene appeared the ancestors of tapirs called Hyrahus and Ofiodont and the herbivorous Taeniodontia resembling modern sloths. The forests were inhabited by small many-knobby and marsupials who survived the Cretaceous-Paleogene disaster.
Dominant among the Paleocene-Eocene predators were cat-like creodonts who were the size of martens. They are considered ancestors to modern Carnivora. Claws on their fingers were blunt and like hooves. The arrangement of their teeth was somwwhat different, with rear grinding teeth retained. Due to this, many Paleogene wildlife researchers have difficulty making a clear distinction between them and the herbivores, or they considered the creodonts either insectivorous or omnivorous (Andrewsarchus was up to 4 m) or possibly even herbivores (Euprotogonia was about a meter long, Dromocyon was the size of a bear). And during the Eocene there were small marten-like predators called Miacids (Miacidae) with carnivorous teeth and jaws similar to their modern predator counterparts.
From the upper Paleocene to middle Eocene, savanna and savanna forests of North America and Europe were inhabited by the giant flightless bird genus Diatryma (genus Gastornis) which reached a height of 2.5 m Their strong legs were help up with a three-toed foot and their massive head reached 40 cm in length and carried a strong slightly-bent beak.
In the Paleocene and Eocene seas lived the cetaceans Basilosaurus with a fish-like body length up to 25 meters and Zeyglodonty with a serpentine body length of up to 21 meters.
