In this article we present the results from the geometric morphometric analyses of morphological variability of the cranial vault in samples belonging to human populations that inhabited the Paraná river delta and the lower basin of the Uruguay river during the late Holocene. The main goal was to present a first approach to the problems related to artificial cranial deformations in the regions mentioned above. Geometric morphometric techniques and multivariate statistical procedures were used in order to quantify patterns of variation among artificial cranial deformations with the aim of contributing from a new line of evidence to the bioarchaeological research that is being carried out in the area. Sixty-five skulls (40 female and 25 male) from nine sites located in different coastal areas were analyzed: the lower and upper delta of the Paraná river and the west bank of the lower basin of the Uruguay river. The results obtained enabled us, on the one hand, to establish relationships between deformation practices and the absolute chronology of the populations of the Paraná river delta in an overall scheme, and to compare them with those proposed for other regions. On the other hand, we were able to establish the existence of geographical and temporal trends in cranial vault deformation practices.
