Biology:Boselaphini
Boselaphini is a tribe of bovines. It contains only two extant genera, each with a single extant species.
Evolution
The Boselaphini or four-horned antelope tribe are the last survivors of a form very similar to that of the ancestors of the broader subfamily. The oldest fossil members of the tribe, such as Eotragus, date to the Miocene about 18 to 20 million years ago. Such fossils possessed horns very similar to those of males belonging to the two living species, although in some cases, they were also present in females.[1] Enamel δ13C values of boselaphins and bovins from the Late Miocene of Pakistan indicates that the former preferred more closed habitats than the latter, which favoured foraging in more open environments.[2]
