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.
