  • The aim of this paper is to present and discuss methodological criteria that may be of use in exploring the role of water in the formation of the faunal record in fluvial and lacustrine environments. As such, the dispersion potential of the bones of adult and neonate guanaco (Lama guanicoe) skeletons in an aquatic environment with very low hydraulic energy is evaluated through experimentation. Results of the experiments are integrated with other, complementary criteria and applied to the bone assemblage recovered at Paso Otero 1 site, situated on the margin of the ancient flood plain of the Quequén Grande River (Buenos Aires Province, Argentina). The results of this study indicate that water was the main agent responsible for guanaco bone accumulation at the site. It is proposed that some of the skeletal parts, which belong to guanaco carcasses that were processed and exploited by hunter-gatherers in areas close to the site, were added to those from animals that died naturally. This resulted in a mixture of material of both natural and anthropic origin.
