Faunas from B1s1 and B1s4 document paleoenvironments during the terminal Pleistocene.
Faunal assemblages are dominated by bovids of the tribes Alcelaphini and Antilopini.
Fauna includes Damaliscus hypsodon, a small extinct alcelaphine.
B1s1 and B1s4 faunal remains are indicative of widespread arid grasslands.
Arid-adapted species disappear or shift their range at the onset of the Holocene.
