Brow Ridge

Superciliary arch, a ridge of bone above the eye orbit. Brow ridges are most noticeable in the fossil erectines and archaic Homo sapiens. In Homo erectus, brow ridges consist of compact bone, but in later stages of human evolution (e.g. archaics) the ridge contained a frontal sinus. The brow ridge is often more pronounced in males, and can be used in skeletal sexing.
