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 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 ...
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 ...
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
The Pleistocene coyote (Canis latrans orcutti), also known as the Ice Age coyote, is an extinct subspecies of coyote that lived in western North America during the Late Pleistocene era. Most remains of the subspecies were found in southern California , though at least one was discovered in Idaho .
Glyptodonts abruptly became extinct approximately 12,000 years ago at the end of the Late Pleistocene, as part of the end-Pleistocene extinction event, along with most other large animals in the Americas. Evidence has been found suggesting that they were hunted by recently arrived Paleoindians, which may have played a role in their extinction. [3]
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]
The last notoungulates, the toxodontids Toxodon, Mixotoxodon and Piauhytherium became extinct at the end of the Late Pleistocene around 12,000 years ago as part of the Late Pleistocene megafauna extinctions, along with most other large mammals in the Americas. The extinction coincides with the arrival of the first humans to the Americas and ...
