There is no general agreement on where the Quaternary extinction event ends, and the Holocene, or anthropogenic, extinction begins, or if they should be considered separate events at all. [244] [245] Some authors have argued that the activities of earlier archaic humans have also resulted in extinctions, though the evidence for this is ...
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 ...
Homo erectus (/ ˌ h oʊ m oʊ ə ˈ r ɛ k t ə s / lit. ' upright man ') is an extinct species of archaic human from the Pleistocene, spanning nearly 2 million years.It is the first human species to evolve a humanlike body plan and gait, to leave Africa and colonize Asia and Europe, and to wield fire.
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 ...
Megatherium became extinct around 12,000 years ago as part of the end-Pleistocene extinction event, simultaneously with the majority of other large mammals in the Americas. The extinctions followed the first arrival of humans in the Americas , and one and potentially multiple kill sites where M. americanum was slaughtered and butchered is known ...
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 ...
Megalonyx jeffersonii became extinct at the end of the Pleistocene, as part of the Quaternary extinction event, in which all other mainland ground sloths and most other large mammals of the Americas became extinct. [11] The youngest confirmed radiocarbon date is in Ohio, dating to 13,180–13,034 calibrated years Before Present. [3]
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]
