steppe bison
The steppe bison〔(Steppe Bison – Yukon Beringia Interpretive Centre ). Beringia.com. Retrieved on 2013-05-31.〕 or steppe wisent (''Bison priscus'') is an extinct species of bison found on steppes throughout Europe,〔(Вестник Кирилло-Белозерского музея 9 (Май 2006) О. Яшина, Т.В. Цветкова – Кирилловский бизон ). Kirmuseum.ru. Retrieved on 2013-05-31.〕 Central Asia, Beringia, and North America during the Quaternary.
==Evolution==
It is believed to have evolved somewhere in South Asia, which would have it appearing at roughly the same time and region as the aurochs with which its descendants are sometimes confused.
The steppe bison became extinct in the early Holocene, as it was replaced in Europe by the modern bison species and in America by a sequence of species (first ''Bison latifrons'', and somewhat later, ''Bison antiquus'') culminating in the modern American bison.
The steppe bison was over 2 m tall at the shoulder, and resembled the modern bison species, reaching 900 kg (2,000 lb) in weight.〔McPhee, R. D. E. (1999) ''Extinctions in Near Time: Causes, Contexts, and Consequences'', Springer, ISBN 0306460920, p. 262.〕 The tips of the horns were a meter apart, the horns themselves being over half a meter long.
