The Late Pleistocene to the beginning of the Holocene saw the extinction of the majority of the world's megafauna (typically defined as animal species having body masses over 44 kilograms (97 lb)), [1] which resulted in a collapse in faunal density and diversity across the globe. [2] The extinctions during the Late Pleistocene are ...
The late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (commonly known as the Middle Pleistocene). [4] The beginning of the Late Pleistocene is the transition between the end of the Penultimate Glacial Period and the beginning of the Last Interglacial around 130,000 ...
Climate change, changes and reductions in the types of vegetation on which they relied, and human predation are all hypothesized to have contributed to the extinction of Palaeolama during the Late Pleistocene or Early Holocene. [4] [2] Evidence from both the paleoecological and fossil records suggest that Palaeolama, among other extinct ...
The New World gomphothere genera Notiomastodon and Cuvieronius dispersed into South America during the Pleistocene, around or after 2.5 million years ago as part of the Great American Biotic Interchange due to the formation of the Isthmus of Panama, becoming widespread across the continent. [28]
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
It evolved during the Pliocene Epoch and became extinct at the end of the Late Pleistocene, living from ~5 million to ~13,000 years ago. [3] The type species, M. jeffersonii (also called Jefferson's ground sloth), the youngest and largest known species, measured about 3 meters (9.8 ft) in length and weighed up to 1,000 kilograms (2,200 lb).

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]
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 ...
