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
Middle Pleistocene Quaternary Stratigraphy's preferred GSSP proposal for the age/stage that should replace the Middle Pleistocene subepoch/subseries. Until the Chibanian is ratified by the IUGS, the Chibanian will remain an unofficial informal, proposed stratigraphic division and "Middle Pleistocene" remains the provisional or quasi-formal name, used by the IUGS on the International Chronostratigraphic Chart for 2018. Middle Pleistocene The Middle Pleistocene is a subdivision of the Pleistocene Epoch, from 781,000 to 126,000 years ago (781–126 ka). It is preceded by the Calabrian stage, beginning with the Brunhes–Matuyama reversal, and succeeded by the Tarantian stage (equivalent ot the Late or Upper Pleistocene), taken as
