At the end of the Pleistocene, during the approximate 3,000 years (roughly from about 13,000-10,000 calendrical years BP), between 35 and 40 species of large mammals went extinct in North America according to E. C. Pielou, a Canadian paleoecologist (1991, After the Ice Age) and her referenced sources. Not all went extinct at the very end of the Pleistocene, but (from a later source; Steven Mithen…After the Ice, 2003) mammoth, mastodon, camel, horse, tapir, Shasta ground sloth and sabre-toothed cat apparently all did. Also, during the fading years of the Pleistocene, other large North American herbivores such as two genera of deer, two genera of pronghorn, stag moose, woodland muskoxen and shrub oxen and, in addition, large carnivores such as American lion and dire wolves also
