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.
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]
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]
Ovis canadensis is one of two species of mountain sheep in North America; the other species being O. dalli, the Dall sheep.Wild sheep crossed the Bering land bridge from Siberia into Alaska during the Pleistocene (about 750,000 years ago); subsequently, they spread through western North America as far south as Baja California and northwestern mainland Mexico.

Pleistocene rewilding is the advocacy of the reintroduction of extant Pleistocene megafauna, or the close ecological equivalents of extinct megafauna. [1] It is an extension of the conservation practice of rewilding , which aims to restore functioning, self-sustaining ecosystems through practices that may include species reintroductions.
Fossils from La Brea show that Pleistocene coyotes were larger and more robust than their modern relatives and actively hunted larger prey. However, Holocene coyote fossils from Pit 10 already show a decrease in size and change in the anatomy of the mandible, indicating that by this point in time coyotes had begun adapting towards conditions ...
During the Pleistocene, Middle Stone Age peoples (e.g., Iwo Eleru people, [4] possibly Aterians), who dwelled throughout West Africa between MIS 4 (71,000 BP) and MIS 2 (29,000 BP, Last Glacial Maximum), [5] were gradually replaced by incoming Late Stone Age peoples, who migrated into West Africa [6] as an increase in humid conditions resulted ...
