Quizplus · Accepted Answer

Australopithecus robustus had large molars, a big face, and a sagittal crest, which is a ridge of bone running along the top of the skull used for attachment of powerful jaw muscles. These features suggest that A. robustus had a diet that required strong chewing, possibly tough plant material, and its skull was adapted to support the necessary jaw muscles.
