Quaternary Time
Quaternary global chronostratigraphical correlation table for the last 2.7 million years. The timescale is based on the internationally-recognised subdivisions of Phanerozoic Eon, Cenozoic Era, Quaternary System or Period; Pleistocene and Holocene Epochs or Series, and finally the Early/Lower, Middle, Late/Upper Pleistocene Subseries, stages or ages, which curerntly are not formalised. So far, two Global Stratotype Section and Points (GSSP) have been ratified within the last 2.7 million years.

Durations of stages, epochs and "Quaternary" on the geologic time scale are according to their span in millions of years. The Neogene Period begins at ~23 Ma (after OGG 2004). - David Bressan, Cryology & co.; Quaternary Palaeoenvironments Group (QPG) Wikipedia; National Geographic; Prehistoric Animals--Quaternary Period MAK111015
