It should be pointed out that although the African rhinos are relatively young compared with the Asian ones, all rhinoceroses can be traced far back into the Tertiary, the Great Indian and Javan to the Upper Pliocene (approximately 5 to 7 million years B. C.), and the Sumatran rhino, even to the Upper Oligocene (approximately 30 million years B. C.) (In comparison the African rhinos date only to the early Pleistocene - approximately one million years B. C.) There are few other mammals, as far as we know, that can be traced back continuously to such a date. This fact alone justifies all efforts to prevent the extinction of the Asiatic rhinos.
