Procesos de formación y efectos tafonómicos en entierros humanos: El caso del sitio paso alsina 1 en patagonia nororiental Argentina

Abstract

The bioarchaeological record from the site Paso Alsina 1 (lower basin of the Colorado river, province of Buenos Aires, Argentina) contributes with important evidences for the knowledge of human populations inhabiting this transitional area between the Pampas and Patagonia during the Final Late Holocene (ca. 1.000-250 years BP). The results from the taphonomic study of two secondary multiple burials from Paso Alsina 1 are presented in this paper. The different analyzed variables allowed to infer the postmortem and postdepositional history of the human bone assemblage. Bioturbation impact was limited but the physical-chemical processes operating in the sedimentary context affected the anatomical integrity of diverse bone elements. On the other hand, the presence of cut marks on several anatomical units indicates human manipulation of some human bodies in the context of mortuary practices.
