Damaliscus hypsodon is an extinct species of antelope from the Middle-Late Pleistocene of Africa. Fossils have been found in Kenya and Tanzania.
Taxonomy
[edit]It was first described in 2012, though its remains were initially discovered in 1990 and went unnamed.[1] The earliest remains are from around 392 to 330 ka,[2] while the latest are from as recently as 12,000 years ago.[1][3]
Description
[edit]Damaliscus hypsodon was a small alcelaphine, only around the size of an impala.[1] The teeth of D. hypsodon showed a degree of hypsodonty greater than living antelopes and comparable to horses, indicating that it was a specialized grazer. Its remains have been found in association with oryx and zebras, which along with its tooth morphology suggest that it lived in open and arid grasslands.[4]
