The brow ridges are often not well expressed in human females, as pictured above in a female skull, and are most easily seen in profile. The brow ridge, or supraorbital ridge known as superciliary arch in medicine, is a bony ridge located above the eye sockets of all primates and some other animals.
With pronounced brow ridges and no chins, the skulls of Neanderthals look different from those of our own species, Homo sapiens, said Dr. Emma Pomeroy, a paleoanthropologist and associate ...
Frontal bossing is the development of an unusually pronounced forehead which may also be associated with a heavier than normal brow ridge. It is caused by enlargement of the frontal bone , often in conjunction with abnormal enlargement of other facial bones , skull , mandible , and bones of the hands and feet.
Early modern people and some living people do however have quite pronounced brow ridges, but they differ from those of archaic forms by having both a supraorbital foramen or notch, forming a groove through the ridge above each eye. [98] This splits the ridge into a central part and two distal parts.

SK 847 has a relatively short and narrow face, pronounced brow ridge, thick supraorbital torus, a sharp sloping frontal bone, delicate curved cheekbones, a rounded forward projecting nasal bones, an obvious supratoral sulcus, and a moderate constriction of the cranium behind the eye socket.
In general, the male skeleton is more robust than the female skeleton because of male's greater muscles mass. Male skeletons generally have more pronounced brow ridges, nuchal crests, and mastoid processes. Skeletal size and robustness are influenced by nutrition and activity levels.
