The significant role of the petrous bone in sex assessment of skeletal human remains has been highlighted by several studies. In previous work we applied the method of the measurement of the lateral angle of the petrous bone to a sample of cremated human remains of known age and sex from an Italian crematorium; the low accuracy of sex classification obtained was probably due to the high number of elderly individuals in our sample. In this paper we investigate the relationship between age and alterations of the petrous bone, by applying the same methodology we used previously, measuring the lateral angle of the petrous bone, in a new sample group that was subdivided into three different age groups. Results showed a moderate rate of accuracy in sex assessment for the first two age groups, for which a new sex-discriminating sectioning point was found; however, the method was found not to be applicable for individuals over 70 years of age. Measurement of the lateral angle in adults aged between 20 and 70 years is a reliable method for sex assessment of cremated remains in conjunction with classical methods, in both archaeological and forensic contexts.

Sex determination in cremated human remains using the lateral angle of the pars petrosa ossis temporalis: is old age a limiting factor?

Abstract

The significant role of the petrous bone in sex assessment of skeletal human remains has been highlighted by several studies. In previous work we applied the method of the measurement of the lateral angle of the petrous bone to a sample of cremated human remains of known age and sex from an Italian crematorium; the low accuracy of sex classification obtained was probably due to the high number of elderly individuals in our sample. In this paper we investigate the relationship between age and alterations of the petrous bone, by applying the same methodology we used previously, measuring the lateral angle of the petrous bone, in a new sample group that was subdivided into three different age groups. Results showed a moderate rate of accuracy in sex assessment for the first two age groups, for which a new sex-discriminating sectioning point was found; however, the method was found not to be applicable for individuals over 70 years of age. Measurement of the lateral angle in adults aged between 20 and 70 years is a reliable method for sex assessment of cremated remains in conjunction with classical methods, in both archaeological and forensic contexts.
