Antilocapra americana (Ord 1815)—PronghornRegional Pleistocene distribution of Antilocapra americana

The Pronghorn is the largest of the regional pronghorns. As described, Stockoceros onusrosagris is somewhat smaller, S. conklingi yet smaller, and Capromeryx notably smaller. However, S. onusrosagris and S. conklingi are treated here as a single species (see Stockoceros account). Fragmentary post-cranial material may not be distinguished with certainty between Antilocapra and Stockoceros and between Stockoceros and Capromeryx.
