The cranial vault is big and ovalThe cranial vault is big and round in shape.The cranial vault is rounded and not as big as the other two.frontal region (is forehead high or low, vertical or sloping? Other?)
The forehead is high and slopingThe forehead is high and slopping. The fronta region is not big.The forehead is low but not too much. The frontal region is verticalForamen magnum position – very close to the back of the skull, or closer to the front (the teeth)?
The foramen magnum is close to the back of the skull.It is close to the back of the skullIt is closer to the frontDegree of prognathism (projecting, snout-like appearance of lower face)There is a high degree of prognathism.The level of prognathism is also high.The degreee of prognathism is lowDental arch shape
(parallel tooth row or parabolic/non-parallel tooth row). Think carefully about this!The tooth rows are parallelThe tooth rows are parralelThe teeth rows are parallelCanine tooth size (either use an online tool, if provided, or compare to other teeth and use descriptions such as much higher than other teeth, even with molars, etc.)
The canine tooth is bigger and project above molars and premolars The canine tooth size is not very big. A. afarensis also has bigger molars almost the same size as the caninesThe canine tooth is small and relatively the same size as the other tee...
