It is a smallish [[ruminant]] [[mammal]] which looks like an [[antelope]]. It is 1.3–1.5 m (4 ft 3 in – 4 ft 11 in) long from nose to tail, and stands 81–104 cm (2 ft 8 in – 3 ft 5 in) high at the shoulder The pronghorn lives in [[North America]]. It lives in the [[prairie]]s, but sometimes also in the [[desert]] and the [[Rocky Mountains]]. The antilocaprids evolved in [[North America]], where they filled a [[niche]] similar to that of the [[bovids]] that evolved in the [[Old World]]. During the [[Miocene]] and [[Pliocene]], they were a diverse and successful group, with many different species. Some had horns with bizarre shapes, or had four, or even six, horns. In [[Africa]], the bovids evolved many ruminants which look like [[deer]] ([[convergent evolution]]). True deer are a different mammal, and do not live in the southern continents. For example, in Africa they are replaced south of the [[Atlas Mountains]] by bovids. The pronghorn is the fastest land mammal in the [[Western Hemisphere]], with running speeds of up to {{convert|55|mph|km/h|abbr=on|order=flip|round=5}}.<ref>{{Cite web|url=https://www.mammalsociety.org/about-asm|title=About ASM {{!}} American Society of Mammalogists|date=2011-03-16|website=www.mammalsociety.org|language=en|access-date=2019-10-31}}</ref> It is often called the second-fastest land animal, second only to the African [[cheetah]], and it can keep up high speeds l
