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.
The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c ...
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 ...
Megalonyx (Greek, "great-claw") is an extinct genus of ground sloths of the family Megalonychidae, native to North America.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]
Cuvieronius is an extinct New World genus of gomphothere which ranged from southern North America to western South America during the Pleistocene epoch. Among the last gomphotheres, it became extinct at the end of the Pleistocene, approximately 12,000 years ago, following the arrival of humans to the Americas.
Arctotherium ("bear beast") is an extinct genus of the Pleistocene short-faced bears endemic to Central and South America. [1] Arctotherium migrated from North America to South America during the Great American Interchange, following the formation of the Isthmus of Panama during the late Pliocene.
Bison antiquus is known from fossils found across North America south of the Laurentide Ice Sheet (whose southernmost extent is around the modern United States-Canada border), ranging from southern Canada (southern Alberta [8] and Ontario [10]) in the north, and Washingon State [11] and California [12] in the west, southwards to Southern Mexico [9] and eastwards to South Carolina and Florida.
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.
