Stockoceros is an extinct genus of the North American artiodactyl family Antilocapridae (pronghorns), [2] known from what is now Mexico and the southwestern United States. [1] The genus survived until about 12,000 years ago, and was present when Paleo-Indians reached North America. [3] [4]
Its horns are each divided near their base into two prongs of roughly equal length. Dental microwear studies suggest that S. onusrosagris was a mixed feeder (both grazing and browsing) with a greater intake of grass into its diet than living pronghorn. [5]
One of the co-discoverers and co-describers of S. onusrosagris was Quentin Roosevelt II, grandson of Theodore Roosevelt; he was 14 at the time of the discovery. [6] [7]
