Late Pleistocene
The Late Pleistocene is a geochronological age of the Pleistocene Epoch and is associated with Upper Pleistocene or Tarantian stage Pleistocene series rocks. 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 age is defined as 9,700 calendar years BCE (before the Common Era). The age represents the end of the Pleistocene epoch and is followed by the Holocene epoch.
Much of the Late Pleistocene age was dominated by glaciation (the Wisconsin glaciation in North America and corresponding glacial periods in Eurasia). Many megafauna became extinct over this age, a trend that continued into the Holocene. Also, human species other than modern humans died out during the Pleistocene. Humanity spread to every continent except for Antarctica during the Late Pleistocene.
==North America==
According to George Carr Frison, ''Bison occidentalis'' and ''Bison antiquus'', an extinct subspecies of the smaller present-day bison, survived the Late Pleistocene period, between about 12 and 11 ka ago. Plains and Rocky Mountain First Nations depended on these bison as their major food source.〔Frison noted that the "oldest, well-documented bison kills by pedestrian human hunters in North America date to about 11,000 years ago".〕 Earlier kills of camels, horses, and muskoxen found at Wally's beach were dated to 13.1–13.3 ka B.P.
