| Abstract | | The problem of correctly sexing unknown skeletal material is given by the contradiction between the discrete classification according to genetically determined sex and the continuous transitions ofsomatic sexual characters of the phenotype. This is true for pelvic bones also, despite the fact that they are the most sexually differentiated bones of the skeleton. The combination of metric characteristics of the two fundamental subsystems ofos coxae (ischiopubic and sacroiliac) is not only necessary but is also sufficient for a multivariate discriminant analysis which separates completely the two sexes in a recent population. The discriminant functions obtained by using the metric characteristics of the individual pelvic segments are less successful, namely in the sacroiliac segment. To improve this result, keeping in mind the problem of sexing in unknown and partial pelvises, we have analyzed a sample ofincisurae by using, instead ofmetric data, shape parametrical descriptions of the boundaries through Fourier analysis. In this work 97 male and 98 female os coxae were considered; the material, of known sex, was of Czech and German origin, dated to the last century (about 1880-1980) from the collections of Institutes ofAnatomy in Prague and Brno, Data acquisition and treatment were performed by means of S.A.M.
