Can"t depict social aspects based on samples of a few teeth and bones. * found foot prints, large skeletal collection, new stone tool evidence* Thick enamel (thickest of all hominins) teeth twice as large as modern humans. Able to eat tough foods (nuts, seeds, tubers, roots) when more preferred foods were short. Prominent sexual dimorphism; male 1. 3m 68kg, female ~1m 45kg. Larger than gracile but still small brain capacity. Not as dentally robust; still large teeth for chewing roots, nuts, seeds, etc. Specimen with lost teeth and bone filled holes in jaw- lived without teeth for long time. Prominent occipital torus thinner cranial vault than h. erectus. Acheulian tools: more complex- levallois technique- core carefully made into tortoise shell shape- struck to pop flake tools out. Used many seasonal foods- coastal foods; shellfish etc.
