Proboscideans are a group of large land mammals. They are characterized by a muscular hand-like nose (the trunk), large ears, and ivory tusks. Elephants first evolved about 50 mya from a large group of unspecialized mammals called Condylarths. The elephants were closely related to the rhinoceros-looking Arsinoitherium but had more specialized teeth, but elephants were only very distantly related to the elephant-like Notoungulate Astrapotheres and Pyrotheres of South America.  Elephants have lived on every continent except Australia and Antarctica.
