The Daka Member is very rich in elephant fossils. Cranial remains of Elephas recki recki were excavated from there during the 1999 and 2002 field seasons. Elephas (Palaeoloxodon) recki is one of the most common faunal elements of the Plio-Pleistocene of eastern Africa. Cranial materials of Elephas recki excavated from the Daka Member are incomplete, and they differ in their preserved portions. The developmental age also differs from specimen to specimen. The cranial features show a number of characters new to eastern African fossil elephants, but their molar features, specifically high hypsodonty and strongly folded enamel, are closely comparable with those of advanced Elephas recki from Olduvai Gorge. These findings shed new light on emigration of palaeoloxodonts from Africa to Eurasia, as well as the taxonomy and spatiotemporal distribution of the Eurasian palaeoloxodont species.
