The Neogene is a geologic period and system in the International Commission on Stratigraphy (ICS) Geologic Timescale starting 23.03 ± 0.05 million years ago and ending 2.588 million years ago. The Neogene Period follows the Paleogene Period as the 2nd period within the Cenozoic Era and is succeeded by the Quaternary Period.

The last epoch into which the Paleogene Period is subdivided is its Oligocene Epoch. The Neogene Period is subdivided into 2 epochs, the earlier Miocene Epoch and its succeeding Pliocene Epoch. The first epoch into which the Quaternary Period is subdivided is its Pleistocene Epoch.[4]
