The Late Pleistocene saw the extinction of many mammals weighing more than 40 kilograms (88 lb), including around 80% of mammals over 1 tonne. The proportion of megafauna extinctions is progressively larger the further the human migratory distance from Africa, with the highest extinction rates in Australia, and North and South America. [11]
Hemiauchenia [1] is a genus of lamine camelids that evolved in North America in the Miocene period about 10 million years ago. This genus diversified and entered South America in the Late Pliocene about three to two million years ago, as part of the Great American Biotic Interchange. The genus became extinct at the end of the
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 ...
Macrauchenia became extinct as part of the end-Pleistocene extinction event at the end of the Late Pleistocene, around 12–10,000 years ago, along with most large mammals native to the Americas. The extinctions followed the arrival of humans in the Americas , [ 34 ] which in South America occurred at least 14,500 years ago (as evidenced by ...
Phoenicopterus copei is an extinct species of flamingo that inhabited North America during the Late Pleistocene. Its fossils have been discovered in Oregon , California , Mexico and Florida . Many of these localities preserve the remains of juvenile individuals, indicating that this species nested at the lakes found there.
Paul Martin at Rampart Cave, home of the Shasta ground sloth in Grand Canyon, ca. 1975. Paul Schultz Martin (born in Allentown, Pennsylvania in 1928, died in Tucson, Arizona September 13, 2010) [1] [2] was an American geoscientist at the University of Arizona who developed the theory that the Pleistocene extinction of large mammals worldwide was caused by overhunting by humans.

Megalonychidae, along with all other mainland ground sloths became extinct in North and South America around the end of the Late Pleistocene, approximately 12,000 years ago, as part of the Quaternary extinction event following the arrival of humans to the Americas. [8]
Eremotherium became extinct at the end of the Late Pleistocene as part of the end-Pleistocene extinction event, alongside other ground sloths and most large mammals across the Americas, though some specimens potentially suggest that Eremotherium might have lived up to the early-middle Holocene.
