Comments
HaRa-VP, Clayhurst Gravel Pit: Four AMS dates were run on the left tibia. A bison scapula collected from the same site by Peter Bobrowsky was also dated (AECV-1558C). This skeleton represents the most complete late Pleistocene bison so far reported in Canada. In contrast to McDonald (1981)... we prefer to view western bison (B.b. occidentalis) as stemming from steppe bison (B. priscus) which may have survived in the northern Yukon until about 12,000 yr BP.... Like other bison, western bison probably fed mainly on grasses, forbs, and sedges.
