In Europe and North America, the Holocene is subdivided into Preboreal, Boreal, Atlantic, Subboreal, and Subatlantic stages of the Blytt-Sernander time scale. There are many regional subdivisions for the Upper or Late Pleistocene, usually these represent locally recognized cold (glacial) and warm (interglacial) periods. The last glacial period ends with the cold Younger Dryas substage. |
The Late Pleistocene (also known as the Upper Pleistocene or the Tarantian) is a stage of the Pleistocene Epoch. The beginning of the stage is defined by the base of the Eemian interglacial phase before the final glacial episode of the Pleistocene 126,000 ± 5,000 years ago. The end of the stage is defined exactly at 10,000 Carbon-14 years BP ("before present"). The stage is followed by the Holocene.
Much of the Late Pleistocene Epoch was dominated by glaciation (the Wisconsin glaciation in North America and corresponding glacial periods in Eurasia). Many megafauna became extinct over this period, a trend that continued into the Holocene. Also, human species other than the modern human died out. Humanity spread to every continent except for Antarctica during the Late Pleistocene.
North American Land Mammal Ages within the Late Pleistocene: Rancholabrean age 0.3 Ma. Upper boundary 0.011 Ma.
