Equus scotti
''Equus scotti'' (translated from Latin as Scott's horse,〔 (2003) ''Annotated Bibliography of Quaternary Vertebrates of Northern North America: With Radiocarbon Dates'', University of Toronto Press, 539 pages ISBN 0-8020-4817-X〕 named after vertebrate paleontologist William Berryman Scott) is an extinct species of ''Equus'', the genus that includes the horse.
==Evolution==
''E. scotti'' was native to North America〔(The Paleobiology Database )〕 and likely evolved from earlier, more zebra-like North American equids early in the Pleistocene Epoch.〔 (1999) The ''Equus (Plesippus) - Equus scotti'' transition in western North America, ''Journal of Vertebrate Paleontology'' 19(3): 74-A〕 The species may have crossed from North America to Eurasia over the Bering land bridge during the Pleistocene. The species died out at the end of the last ice age in the large-scale Pleistocene extinction of megafauna.
It was among the last of the native horse species in the Americas until the reintroduction of the horse approximately 10,000 years later, when conquistadors brought modern horses to North and South America circa 16th century, some of which later escaped to the wild and became ancestors of the many feral horses living today in the Americas.
