"Prehistoric Nutcracker Suite" Video Description for the Visually Impaired
In this computer model of the cranium of Australopithecus africanus, an early hominid, bright colors indicate high stresses as the animal chews hard objects with the premolar teeth. The model indicates that a bony pillar running alongside the opening of the nasal cavity acts as a reinforcing strut to support premolar loads.
