insert Definition (id: null
text: The Eocene is the second of five epochs in the Tertiary Period — the second
of three epochs in the Paleogene — and lasted from about 55.8 to 33.9 million years
ago. The oldest known fossils of most of the modern orders of mammals appear in a
brief period during the early Eocene and all were small, under 10 kg. Both groups
of modern ungulates, Artiodactyla and Perissodactyla, became prevalent mammals at
this time, due to a major radiation between Europe and North America.
