An ancient bison from the mouth of the Rauchua River (Chukotka, Russia)
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 sides, several vertebrae, bones of the foreli...
