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 was the time when most animals evolved to resemble modern-day animals and they managed to live through the Late mid-Pleistocene since there were no extinction events of megafauna until the end of the Late Pleistocene.
The Toba eruption (also called the Toba supereruption and the Youngest Toba eruption) was a supervolcanic eruption that occurred around 74,000 years ago, during the Late Pleistocene, [2] at the site of present-day Lake Toba, in Sumatra, Indonesia.
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 ...
The largest extinction was the Kellwasser Event (Frasnian-Famennian, or F-F, 372 Ma), an extinction event at the end of the Frasnian, about midway through the Late Devonian. This extinction annihilated coral reefs and numerous tropical benthic (seabed-living) animals such as jawless fish, brachiopods , and trilobites .
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]
The 12-by-20-square-foot space was outfitted last summer with roughly 140 plants representative of the late Cretaceous: spiky palms, feathery metasequoia, frilly ferns.
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]
