Pleistocene coyote Pleistocene coyote The Pleistocene coyote ("Canis latrans orcutti"), also known as the Ice Age coyote, is an extinct subspecies of coyote that lived in western North America during the Late Pleistocene era. Most remains of the subspecies were found in southern California, though at least one was discovered in Idaho. It was part of a carnivore guild that included other canids like foxes, gray wolves, and dire wolves. Compared to their modern Holocene counterparts, Pleistocene coyotes were larger and more robust, weighing , likely in response to larger competitors and prey rather than Bergmann's rule. Their skulls and jaws were
Pleistocene "Homo erectus" for much of the Pleistocene. Acheulean lithics appear along with "Homo erectus", some 1.8 million years ago, replacing the more primitive Oldowan industry used by "A. garhi" and by the earliest species of "Homo". The Middle Paleolithic saw more varied speciation within "Homo", including the appearance of "Homo sapiens" about 200,000 years ago. According to mitochondrial timing techniques, modern humans migrated from Africa after the Riss glaciation in the Middle Palaeolithic during the Eemian Stage, spreading all over the ice-free world during the late Pleistocene. A 2005 study posits that humans in this migration interbred with archaic human
