The emphasis placed on the study of larger vertebrates, the complexity in the taphonomic stories of rodents and the low specific modifications observed, limited the study of these animals from Patagonian archaeological sites. In order to advance in the understanding of the subsistence strategies displayed by hunter-gatherers in Patagonian forests, this research presents the study of rodent bone assemblages recovered in two archaeological sites: Paredón Lanfre (SW Río Negro) and Risco de Azócar 1 (NO Chubut). The taphonomic analysis included the estimation of the MNE and MNI, the relative abundance, and the representation of skeletal elements. Heat alteration of bone surface and the presence of cut marks and digestion traces were also evaluated. Caviomorph rodents dominate the small vertebrate?s assemblages. Termo-alteration patterns and differential representation of skeletal parts ?over-representation of skull and distal elements of the limb- suggest that human consumption was the main cause of accumulation of these rodents. The consumed species were Galea leucoblephara, Microcavia australis, Ctenomys haigi and possibly also C. sociabilis.
