The snow sheep, Ovis nivicola, or Siberian bighorn sheep, is a species of sheep from the mountainous areas in the northeast of Siberia. One subspecies, the Putorana snow sheep, lives isolated from the other forms on the Putorana Plateau. Seven subspecies are listed: the Kolyma, Koryak, Okhotsk, Yakutian, Kamchatkan, Putorana and Chukotka snow sheep. Ovis nivicola appeared about 600,000 years ago. A number of these wild sheep crossed the Bering Land Bridge from Siberia into Alaska during the Pleistocene, and new and extant lineages created from this migration include the North American Dall sheep, or thinhorn sheep, and the bighorn sheep.
