Late Pleistocene

The Late Pleistocene is an unofficial sub-epoch in the international geologic timescale in chronostratigraphy. It is intended to be the third division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently estimated to span the time between c. 126,000 and c. 11,700 years ago. The Late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian and succeeded by the officially ratified Greenlandian. The estimated beginning of the Tarantian is the start of the Eemian interglacial period . It is held to end with the termination of the Younger Dryas, some 11,700 years ago when the Holocene Epoch began.
The term Late Pleistocene is currently in use as a provisional or "quasi-formal" designation by the International Union of Geological Sciences . The International Chronostratigraphic Chart labels the last two Pleistocene divisions as Middle and Upper, spanning 773–126 ka and 126–11.7 ka, respectively. Although the three oldest ages of the Pleistocene have been officially defined, the Late Pleistocene has yet to be formally defined, along with consideration of a proposed Anthropocene sub-division of the Holocene.
