Human subsistence and environmental stability during the last 2200 years in Epullán Chica cave (northwestern Patagonia, Argentina): A perspective from the zooarchaeological record

Abstract:

The faunal content from Epullán Chica archaeological site (ECh, thereafter), a small cave located in northwestern Patagonia, Argentina, was studied from taphonomic and paleoenvironmental points of view. This cave is placed in the ecotone between Monte desert and the Patagonian steppe, in the middle Limay River basin, was occupied since the end of the Late Holocene. Zooarchaeological evidence retrieved from ECh is diverse, including fresh-water mollusk shells (Diplodon chilensis), eggshell and bone fragments of Rheidae, bones and teeth of large (Lama guanicoe), medium (e.g., Chaetophractus villosus, Conepatus chinga), and micro-sized (several species of sigmodontine and caviomorph rodents) mammals. Most of the recorded taxa were the result of human exploitation. However, owl pellets preserved in the sediments, and other taphonomic signatures, clearly indicate that avian predators are …
