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
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 ...
Harold Urey argued that comet impacts may have caused mass extinctions in the past and may have been responsible for demarcating the periods of the geologic time scale. [27] 1974. Jan Smit began studying the extinction of foraminifera at the K–T boundary in Caravaca, Spain. He observed that some of these extinctions must have been rapid. [28 ...

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
The Late Pleistocene witnessed the spread of modern humans outside of Africa as well as the extinction of all other human species. Humans also spread to the Australian continent and the Americas for the first time, co-incident with the extinction of most large-bodied animals in these regions.
The second mass extinction was the Late Devonian extinction, probably caused by the evolution of trees, which could have led to the depletion of greenhouse gases (like CO 2) or the eutrophication of water. 70% of all species became extinct. [179] The third mass extinction was the Permian-Triassic, or the Great Dying, event.
