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]
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 ...
A major extinction event of large mammals , which included mammoths, mastodons, saber-toothed cats, glyptodons, the woolly rhinoceros, various giraffids, such as the Sivatherium; ground sloths, Irish elk, cave lions, cave bears, Gomphotheres, American lions, dire wolves, and short-faced bears, began late in the Pleistocene and continued into ...
[7] [8] [2] Also, some evidence suggests a move to northern South America during the second of two Pleistocene Camilidae migration events. [8] Fossil evidence ranges from the southern extent of North America (including California, Florida, and Mexico) south through Central America, and terminates in South America (Argentina and Uruguay).

Bison antiquus is an extinct species of bison that lived in North America during the Late Pleistocene from over 60,000 years ago until around 10,000 years ago. Bison antiquus was one of the most common large herbivores in North America during this time period. It is the direct ancestor of the living American bison. [1] [2]
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]
However, the migration was halted at the North American Ice Sheet, which separated Beringia and southern North America for most of the Late Pleistocene. [228] Both humans and Arctodus are first dated to ~50,000 BP in Beringia, both from sites in the Yukon, and co-existed until Arctodus went extinct in Beringia ~23,000 BP during the Last Glacial ...
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]
