Original diagnosis:?Incisors and canines similar in size to Homo africanus (Dart, 1925) and Homo habilis L.S.B. Leakey, Tobias and Napier, 1964, but premolars and, especially, molars much smaller; premolars less narrow than in Homo habilis and with roots reduced in number, often only a single root is present; lower P4 seems to tend to have relatively smaller crown surface than lower P3; cranial capacity substantially larger than in Homo africanus, apparently as in Homo habilis or somewhat more; mandible rather thick and massive." |
