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]
Over 50 genera (~ 83%) of megafauna in South and North America went extinct during the Pleistocene. [42] most mega mammals (>1000kg) and large mammals (>40kg) went extinct by the end of the Late Pleistocene. [43] During this period there was a major cooling event called the Younger Dryas and the Clovis culture of capturing game became more ...
Extinct in the late Pleistocene or early Holocene. [2] Capromys pilorides lewisi: Grand Cayman, Cayman Brac, and Little Cayman, Cayman Islands Most recently dated in Grand Cayman to 1439-1643 and in Cayman Brac to 1440–1624. A 1585 reference by Francis Drake to "coneys" and cat-sized "little beasts" on the islands could refer to this animal. [10]
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Late Pleistocene or Early Holocene – and before recorded history, specifically before they could be studied alive by ornithological science. They had died out before the period of global scientific exploration that started in the late 15th ...
Found in the late Pleistocene to early Holocene of Upper Ribeira Valley, southeastern Sao Paulo, Brazil but without direct datation. [7] Glyptotherium cylindricum: Florida and Texas to northeastern Brazil: Found in the late Pleistocene to early Holocene of Serra do Ramalho, Brazil but without direct datation. [8] Hoplophorus euphractus: Eastern ...
Late Pleistocene bighorn sheep were more slender and had longer legs than their descendants today. Scientists believe that the change in predator fauna after the late Pleistocene extinctions resulted in a change of body shape as the species adapted for increased power rather than speed. [31]
This is a list of Ice Age species preserved as permafrost mummies during the Late Pleistocene. It includes all known species that have had their tissues partially preserved within the permafrost layer of the Arctic and Subarctic. Most went extinct during the Late Pleistocene extinctions while some are still extant today. They have been listed ...
A. pristinus went extinct around 300,000 years ago, with A. simus disappearing ~12,800 years ago in the Late Pleistocene extinctions. The cause behind these extinctions is unclear, but in the case of A. pristinus , this was likely due to climate change and competition with other ursids, such as the black bear and Tremarctos floridanus .
