Pelorovis ("prodigious/monstrous sheep" [1]) is an extinct genus of African bovines which existed during the Pleistocene epoch. Originally believed to be a giant member of Caprinae, related to modern sheep, it is now known to be a relative of cattle and buffalos.

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.

Natural Trap Cave is a pit cave in the Bighorn Mountains, in northern Wyoming, United States.Excavations in the cave are an important source of paleontological information on the North American Late Pleistocene, due to a rich layer of fossils from animals that became trapped in the cave.
The exact line of descent from wild ancestors to domestic sheep is unclear. [2] The most common hypothesis states that Ovis aries is descended from the Asiatic (O. gmelini) species of mouflon; the European mouflon (Ovis aries musimon) is a direct descendant of this population. [3]
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.
It was the size of a sheep, weighing probably up to 30 kg (66 lb). [37] The largest known ornithorhynchid is Obdurodon tharalkooschild, it was even larger than 70 cm (28 in)-long Monotrematum sudamericanum. [38] Kollikodon ritchiei was likely the largest monotreme in the Mesozoic. Its body length could be up to a 1 m (3 ft 3 in). [39]
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 mammoth steppe.
