Gracile Australopithecine

Hominid with small back teeth, face and body, as compared with the larger, more robust australopithecine species (see Paranthropus). Gracile australopithecines lived in Africa between about 4 and 2 million years ago. Like the robust forms, the gracile forms were not highly encephalized, possessing an average cranial capacity of about 450 cm3 and relatively small body masses of 34-45 kg (75-100 lb).
