MAZZA, Bárbara. Determinación sexual en cráneos de sitios arqueológicos del humedal del paraná inferior: Una aproximación desde análisis cualitativos y cuantitativos. Rev Arg Antrop Biol [online]. 2013, vol.15, n.1, pp.15-28. ISSN 1514-7991.

Sex determination on human bone remains in bioarchaeology constitutes a special issue to perform interpretations on behavioral and cultural aspects of past societies. The aim of the present work is to discuss the application of qualitative and quantitative methodologies on a sample of 110 skulls of adult individuals of both sexes from archaeological sites of the Paraná inferior Wetland (Argentina), with the purpose to obtain an adequate sexual discrimination for the present sample and to evaluate the efficiency of those methodologies. The qualitative variables recorded include degrees of sexual dimorphism in the glabella, supraorbital margin, mastoid process, nuchal crest and in the mental eminence according to an ordinal system of expression (scoring). The metric analysis was carried out on the mastoid process using the following measures: maximum breath, minimum breath, transversal breath, horizontal breath, porion- mastoidale length, asterion-mastoidale length, vertical porion-mastoidale length and area surface calculation. All variables presented statistically significant differences and high discrimination percentages. Subsequently a discriminant function was elaborated using those metric variables that better discriminated between sexes. Even though a good sexual discrimination was achieved through qualitative and quantitative analyses, the results suggest that both should be implemented to increase the precision in the results.
