A Partial Bison (Bison cf. B. latifrons) Skeleton from Chuchi Lake, and its Implications for the Middle Wisconsinan Environment of Central British Columbia

Fragmentary but massive left and right horncores, found with eight post-cranial bones, from a clay unit underlying a diamicton of the last (Fraser) glaciation at Chuchi Lake, British Columbia probably represents an individual giant bison (Bison cf. B. latifrons). A sample of bone from one of the hor...
