Pronghorn

The Pronghorn (Antilocapra americana), is a species of artiodactyl mammal native to interior western and central North America. Though not an antelope, it is often known colloquially in North America as the Prong Buck, Pronghorn Antelope, Speedgoat, or simply Antelope, as it closely resembles the true antelopes of the Old World and fills a similar ecological niche due to convergent evolution. It is the only surviving member of the family Antilocapridae.
