The extinctions during the Late Pleistocene are differentiated from previous extinctions by its extreme size bias towards large animals (with small animals being largely unaffected), and widespread absence of ecological succession to replace these extinct megafaunal species, [3] and the regime shift of previously established faunal ...
Pliocene–Pleistocene boundary extinction: 2 Ma: Possible causes include a supernova [7] [8] or the Eltanin impact [9] [10] Middle Miocene disruption: 14.5 Ma Climate change due to change of ocean circulation patterns. Milankovitch cycles may have also contributed [11] Paleogene: Eocene–Oligocene extinction event: 33.9 Ma
Biological taxa that went extinct during the Pleistocene epoch of geologic time, between 2.58 million and 11.7 thousand years ago, during the early Quaternary Period of the Cenozoic Era See also the preceding Category:Pliocene extinctions and the succeeding Category:Holocene extinctions
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 ...
The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -stoh-; [4] [5] referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.
A marsupial lion skeleton in the Naracoorte Caves, South Australia. The term Australian megafauna refers to the megafauna in Australia [1] during the Pleistocene Epoch.Most of these species became extinct during the latter half of the Pleistocene, and the roles of human and climatic factors in their extinction are contested.
Mass extinctions are very important to how life evolved on Earth. For example, when an asteroid hit the Earth 66 million years ago, the resulting dinosaur extinction led mammals to take their place.
Highly specialised for grazing, with the narrowest range of all Pleistocene ground quirrels. The latest possible date is the Atlantic, and its extinction was probably related to the local collapse of the mammoth steppe.
