(7-16) The features of the greater sciatic notch are characteristic and are commonly used for sexual dimorphism.
Osteologists vary widely in their experience with known collection of sex determining parameters, and this undoubtedly influences the amount of weight they give in sex determination to the differences in the shape of the greater sciatic notch. Such inconsistencies make demographic comparisons of collections studied by different investigators difficult.
Maximum depth (OC) was determined between the base line (AB) and the deepest point (C) of the greater sciatic notch. OB was designated as the posterior segment of width of the greater sciatic notch.
The following parameters of the greater sciatic notch were considered:
states that the precision of sex determination using the morphology of the greater sciatic notch to describe its shape corresponds directly to an estimation of the discriminatory power (varying by around 70%) of this trait.
