Document Summary

Baker | fors 3331 | spring 2017 | lecture 19 | page 1. In this lecture, we"ll tackle techniques for determining the sex (not gender!!) of select skeletal materials. We"ll focus on the head (cranium and mandible) and hips (innominates and sacrum) Humans are somewhat sexually dimorphic: as a result, we can often determine sex (not gender) from skeletal remains. Sexual differences appear after maturity so determining the sex of juveniles is incredible difficult and next to impossible using skeletal clues. Adult female skeletal elements are generally smaller and lighter in construction (i. e. gracile) Adult male skeletal elements are generally larger, more robust, and rugose (i. e. have strong muscular relief) Sexes will overlap near the center of the distribution(s) There is also variation between populations, as some have larger males and females (e. g. caucasians) Skeletal sex differences are most extreme in the skull and pelvis, with the pelvis being a preferred/better indicator.
