This Genus is characterized by large, barrel-shaped grazing antelopes. Today the Genus is confined to the sub-Saharan African continent, but skeletal remains have been unearthed in certain parts of Europe and India. Up to the year 1800 the Hippotragus Genus was represented by three disticnt species. Although more species are known from the so-called "Pleistocene", these were probably only the larger, post-flood ancestors of the modern, living species. Today, although very distinct, the two living species, the Roan antelope (Hippotragus equinus) and Sable antelope (Hippotrags niger), are closely related and in some areas like Angola they are known to live in mixed herds, freely producing fertile offspring.
