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.

Late Pleistocene Late Pleistocene The Late Pleistocene is a geochronological age of the Pleistocene Epoch and is associated with Upper Pleistocene (or Tarantian) stage rocks. The beginning of the stage is defined by the base of the Eemian interglacial phase before the final glacial episode of the Pleistocene 126,000 ± 5,000 years ago. Its end is defined at the end of the Younger Dryas, some 11,700 years ago. The age represents the end of the Pleistocene epoch and is followed by the Holocene epoch. Much of the Late Pleistocene age was dominated by glaciations, such as the Wisconsin glaciation in North America
