Elephas

Asian elephant Elephas maximus photographed by Manoj Sindagi.


Belongs within: Elephantidae.

Though represented in the modern fauna only by the Asian elephant Elephas maximus, the genus Elephas is first recorded in the middle Pliocene of eastern and southern Africa, spreading from there into the Middle East by the later Pliocene (Coppens et al. 1978). The genus remained widespread in the Old World until it became extinct in Africa and Europe in the late Pleistocene.

Characters (from Coppens et al. 1978): Skull high, forehead fore-shortened. Premaxillary tusk sockets generally widely separated, tusks usually gently curved in a single plane. Frontoparietal surface flat to concave; upper borders of the temporal fossae forming sharp, raised ridges. Mandible corpus strongly convex laterally, condyles transversely elongated and directed upward and inward.
