Pleistocene may be found at elevations of several hundred meters. Pleistocene The Pleistocene (, often colloquially referred to as the Ice Age) is the geological epoch which lasted from about 2,588,000 to 11,700 years ago, spanning the world's most recent period of repeated glaciations. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The Pleistocene is the first epoch of the Quaternary Period or sixth epoch of the Cenozoic Era. In the ICS timescale, the Pleistocene is divided into four stages or ages, the

Some carnivores and omnivores survived the end of the Pleistocene era and were widespread in North America until Europeans arrived, such as grizzly bears, cougars, jaguars, grey and red wolves, bobcats, and coyotes. The cheetah could serve as a substitute for "Miracinonyx", keeping the population of pronghorns in check. Jaguars could be reintroduced back to areas of North America to control populations of prey animals. Some of the larger cats such as the African lion could act as a proxy for the Pleistocene American lion, they could be introduced to
