long-horn bison

Encyclopedia Article


Also spelled longhorn, the long-horn bison was a large mammal that went extinct toward the end of the Pleistocene epoch, either because of climate change, human interference in the form of hunting, or a combination of both. Longhorned bison, or giant Ice Age bison, had a horn span of up to six feet and a body mass up to fifty-percent greater than that of today's bison.
