Predict Sex Is Better Than Postcranial Measurements

predict sex was better than postcranial measurements. Additionally, sexual dimorphic features show large variation within and between populations (Keen, 1950; Acsádi, and Nemeskeri, 1970; Workshop of European Anthropologists, 1980; Ubelaker, 1984; Krogman and İşcan, 1986). Some sites on the skull have shown a wide range within sex variation making them less reliable for sex determination. For example, a projecting nuchal crest is typically associated with a male skull but can also appear on a female skull, similarly non-projecting nuchal crests, typically associated with a female skull, can also appear on a male skull (Gulekon and Turgut, 2003; Klepinger, 2006). Yet, this and others, are still some of most commonly used sites for sexing. Keen (1950) expressed that because morphology is often related to size and robustness, determining sex is extremely difficult unless extreme features are expressed, such as a very small mastoid process that projects only a small distance for females and a massive mastoid process that projects a great distance from the inferior margins of the skull for males. Furthermore Meindl et al. (1985) and Walker (1995) have discussed that the morphology of sites on the skull of both sexes appear more masculine as the person ages, which would also hinder the accuracy of determining the sex of skeletal remains. Buikstra and Ubelaker (1994, p.16) also caution that "estimation of sex can be difficult if the observer is not familiar with the overall pattern
