Alcelaphine cheek teeth are adapted for a grass rich diet. They are high crowned and the cheek teeth have distinctive curved arcades, without basal pillars. This adult right mandible has its first molar through to the third molar in wear.
Alcelaphini are medium to large grass eating antelope, that are adapted to running in the open grasslands they inhabit. Modern species of Alcelaphines range in size from the 60 Kg - 230 kg. At least seven Alcelaphine species are known from the upper levels of the Turkana Basin strata. Antelope species are more easily determined from horncores than from teeth. In modern Alcelaphines, both males and females have horns.
