The Pliocene (Pleiocene in older texts) was a short geological epoch at the end of the Neogene. It is also the fifth and final epoch of the former Tertiary period and the fifth epoch of the Cainozoic. It began 5.3 million years ago and ended 2.6 million years ago. The Pliocene follows the Miocene and is followed by the Pleistocene.
