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 ...
Paul Martin at Rampart Cave, home of the Shasta ground sloth in Grand Canyon, ca. 1975. Paul Schultz Martin (born in Allentown, Pennsylvania in 1928, died in Tucson, Arizona September 13, 2010) [1] [2] was an American geoscientist at the University of Arizona who developed the theory that the Pleistocene extinction of large mammals worldwide was caused by overhunting by humans.

Bison antiquus is known from fossils found across North America south of the Laurentide Ice Sheet (whose southernmost extent is around the modern United States-Canada border), ranging from southern Canada (southern Alberta [8] and Ontario [10]) in the north, and Washingon State [11] and California [12] in the west, southwards to Southern Mexico [9] and eastwards to South Carolina and Florida.
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
Megatherium (/ m ɛ ɡ ə ˈ θ ɪər i ə m / meg-ə-THEER-ee-əm; from Greek méga 'great' + theríon (θηρίον) 'beast') is an extinct genus of ground sloths endemic to South America that lived from the Early Pliocene [1] through the end of the Late Pleistocene. [2]
Miracinonyx (colloquially known as the "American cheetah") is an extinct genus of felids belonging to the subfamily Felinae that was endemic to North America from the Pleistocene epoch (about 2.5 million to 16,000 years ago) and morphologically similar to the modern cheetah (Acinonyx jubatus), although its apparent similar ecological niches have been considered questionable due to anatomical ...
David Jeffrey Meltzer (born 1955) is an American archaeologist known for his influential studies of Paleo-Indians and Pleistocene mammalian extinction in the Americas.He is currently Henderson-Morrison Professor of Prehistory at Southern Methodist University and Affiliate Professor at the Centre for GeoGenetics at the University of Copenhagen.
Equus scotti (translated from Latin as Scott's horse, [1] named after vertebrate paleontologist William Berryman Scott) is an extinct species of horse native to Pleistocene North America. [ 2 ] Evolution
