The form of the supraorbital margin as a criterion in identification of sex from the skull: Investigations based on modern human skulls

Sexual dimorphism in the shape of the supraorbital margin was reported by B roca and various subsequent authors, but no consistently applied, precise d efinition has been established. In this study of modern human skulls, the v alue of our definition of the sex-related difference in this area in the id entification of sex from the skull was investigated. It was found that this feature can be assessed reliably, is strongly related to sex, and is indep endent of the side. The accuracy of identification of sex using this method alone was found to be about 70%. (C) 1999 Wiley-Liss, Inc.
