The Neogene ( ) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period Ma (million years ago) to the beginning of the present Quaternary Period Ma. It is the second period of the Cenozoic and the eleventh period of the Phanerozoic. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene.
