An ancient bison from the mouth of the Rauchua River (Chukotka, Russia)
© 2015 University of Washington. An incomplete carcass of an extinct bison, Bison ex gr. priscus, was discovered in 2012 in the mouth of the Rauchua River (69°30'N, 166°49'E), Chukotka. The carcass included the rump with two hind limbs, ribs, and large flap of hide from the abdomen and sid...
