One North American mammal, the pronghorn or "pronghorn antelope", is colloquially referred to as the "American antelope", despite the fact that it belongs to a completely different family (Antilocapridae) than the true Old-World antelopes; pronghorn are the sole extant member of an extinct prehistoric lineage that once included many unique species.
The Antilocapridae are a family of ruminant artiodactyls endemic to North America. Their closest extant relatives are the giraffids. [1] Only one species, the pronghorn (Antilocapra americana), is living today; all other members of the family are extinct. The living pronghorn is a small ruminant mammal resembling an antelope.
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes (including goat-antelopes), sheep and goats. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 (or two) major subfamilies and
The 146 extant species of Bovidae are split into 53 genera within 9 subfamilies: Aepycerotinae, or the impala; Alcelaphinae, containing the bontebok, hartebeest, wildebeest, and relatives; Antilopinae, containing several antelope, gazelles, and relatives; Bovinae, containing cattle, buffalos, bison, and other antelopes; Caprinae, containing ...
The subfamily Caprinae, [1] also sometimes referred to as the tribe Caprini, [2] is part of the ruminant family Bovidae, [3] and consists of mostly medium-sized bovids. A member of this subfamily is called a caprine. [4] Prominent members include sheep and goats, with some other members referred to as goat antelopes.
It is the only surviving member of the family Antilocapridae. [7] During the Pleistocene epoch, about 11 other antilocaprid species existed in North America, many with long or spectacularly-twisted horns. [8] Three other genera (Capromeryx, [9] [10] Stockoceros [11] [12] and Tetrameryx [13]) existed when humans entered North America but are now ...

Molecular studies by molecular systematists, based on DNA analysis, in the early 21st century have revealed new relationships among mammal families. Classification systems based on molecular studies reveal three major groups or lineages of placental mammals, Afrotheria, Xenarthra, and Boreoeutheria. which diverged from early common ancestors in the Cretaceous.
