a bony ridge on the skull extending from the forehead to the back of the head
a bony ridge on top of the skull to which chewing muscles attach) Australopithecus robustus Robustus had a body similar to that of africanus, but a larger and more robust skull and teeth
prominent point on top of the head where two skull bones meet
bony ridge running along the top midline of the cranium
ridge at the midline of the skull for the attachment of temporalis muscles (i.e., robust australopithecines).
A sagittal crest is a ridge of bone running lengthwise along the midline of the top of the skull (at the sagittal suture) of many mammalian and reptilian skulls, among others. The presence of this ridge of bone indicates that there are exceptionally strong jaw muscles. The sagittal crest serves primarily for attachment of the temporalis muscle, which is one of the main chewing muscles.
