Abstract In order to identify the weapons systems used along the Holocene in Southwest Buenos Aires Province, the variability of projectile points recovered at nine archaeological sites is analyzed. Univariate and multivariate statistical, descriptive and inferential analysis of the metric variables, resulted in the recognition of four statistical groups, based on the relationship between length, width and thickness. Seven morphological groups were identified based on the different morphologies of limbs and bases. The result of techno-typological analysis allowed us to identify different manufacturing techniques, the presence of maintenance and the different raw material used.
