Paleogene is a geological term that refers to a period that spans approximately 25 million years. Synonyms for Paleogene include Eocene, Oligocene, and Miocene.

The Eocene is notable for the proliferation of modern mammal groups, including primates, artiodactyls, and perissodactyls.

The Miocene is known for its diverse fauna, including early hominins, mastodons, and toothed whales.
