The extinctions during the Late Pleistocene are differentiated from previous extinctions by its extreme size bias towards large animals (with small animals being largely unaffected), and widespread absence of ecological succession to replace these extinct megafaunal species, [3] and the regime shift of previously established faunal ...
Pliocene–Pleistocene boundary extinction: 2 Ma: Possible causes include a supernova [7] [8] or the Eltanin impact [9] [10] Middle Miocene disruption: 14.5 Ma Climate change due to change of ocean circulation patterns. Milankovitch cycles may have also contributed [11] Paleogene: Eocene–Oligocene extinction event: 33.9 Ma
Over 50 genera (~ 83%) of megafauna in South and North America went extinct during the Pleistocene. [42] most mega mammals (>1000kg) and large mammals (>40kg) went extinct by the end of the Late Pleistocene. [43] During this period there was a major cooling event called the Younger Dryas and the Clovis culture of capturing game became more ...
Cuvieronius is an extinct New World genus of gomphothere which ranged from southern North America to western South America during the Pleistocene epoch. Reaching a shoulder height of 2.3 metres (7.5 ft) and a body mass of 3.5 tonnes (7,700 lb), it was on average shorter but comparable in body mass to an Asian elephant.
During the Pleistocene epoch, four species of tapir are known to have inhabited North America. Along with T. merriami , Tapirus californicus also lived in California, Tapirus veroensis was found in Florida, Georgia, Kansas, Missouri and Tennessee, and Tapirus copei was found from Pennsylvania to Florida.

Morenelaphus is an extinct genus of capreoline deer that lived in South America during the Pleistocene, ranging from the Pampas to southern Bolivia and Northeast Brazil. There is only a single recognised species, Morenelaphus brachyceros. It was a large deer, with some specimens estimated to exceed 200 kilograms in body mass. [1]
Scientists believe that the change in predator fauna after the late Pleistocene extinctions resulted in a change of body shape as the species adapted for increased power rather than speed. [31] The extinctions hardly affected Africa but were especially severe in North America where native horses and camels were wiped out.
