The Miocene Epoch (23 million to 5.3 million years ago) is probably the most fruitful... During the Miocene, land-dwelling mammals were essentially modern; many archaic groups were extinct by the end of the preceding Oligocene, and fully half of the mammalian families known today are present in the Miocene record.

What was the climate like 18 million years ago?

Oligocene Epoch

This map shows how North America appeared 18 million years ago. River systems in the Rocky Mountains continued to carry erosional sediments to Nebraska during the Miocene. The climate was cool and dry compared to the tropical Paleocene and Eocene Epochs.
