Pintubi-1 is a typical Aboriginal skull from early 1900s New South Wales Bindaboo Tribe. Australoid skulls have squared jaws, pronounced brows, and unique dental features. Australoids possess the largest brow ridges of any race. These features make Australoids the easiest race to identify by skull. Pintubi-1 represents modern Aboriginal people. Caucasoid skulls are the standard reference making others appear primitive. Large morphological differences exist between Australoid and Caucasian skulls. Australoids form one of three basic skull groups.
