 Bison or buffalo are large, even-toed ungulates in the genus Bison within the subfamily Bovinae. Two extant and four extinct species are recognized. Of the four extinct species, three were North American: Bison antiquus, B. latifrons, and B. occidentalis. The fourth, B. priscus, ranged across steppe environments from Western Europe, through Central Asia, and onto North America. https://en.wikipedia.org/wiki/Bison
