Antidorcas recki

Antidorcas recki is an extinct species of gazelle, related to the extant springbok, from the Pliocene and Pleistocene of southern and eastern Africa.

In 1965, Louis Leakey referred two cranial fragments from Olduvai Gorge to Phenacotragus.

[4] Alan William Gentry later wrote about gazelle material recovered from Olduvai, assigning several skull fragments to Gazella wellsi.

He noted the similarities between G. wellsi and P. recki, and suggested they be sunk into the genus Antidorcas, but hesitated to synonymise them.

[3][7] Similar to the modern springbok, Antidorcas recki was sexually dimorphic, with males having flattened horn cores that bent backwards sharply, and females having slender, straight cores with a round cross-section.
