Pronghorn
I didn’t know a pronghorn was an animal. However, I have reaffirmed my love of Wikipedia:
Though not an antelope, it is often known colloquially in North America as the Prong Buck, Pronghorn Antelope, or simply Antelope, as it closely resembles the true antelopes of the Old World and one theory is that it fills a similar ecological niche due to convergent evolution. It is the only surviving member of the family Antilocapridae.
