          Abstract

          Desde una perspectiva tafonómica y paleoambiental se estudiaron restos de micromamíferos recuperados de dos sitios arqueológicos que abarcan un período temporal desde 3.800 años a.p. hasta el siglo XX y se ubican en el curso medio del río Grande, sudoeste de la provincia de Mendoza (Cueva de Luna y Alero Puesto Carrasco). La presencia de marcas de digestión ligera y moderada indica que los micromamíferos fueron depositados por aves strigiformes, posiblemente Tyto alba. Esto contrasta con el modelo de intensificación de los recursos planteado para los grupos cazadores-recolectores que habitaron el sur de Mendoza hacia el 2.000 a.p. Los conjuntos zooarqueológicos mostraron cierta estabilidad taxonómica, presentando especies patagónicas (p.ej. Lestodelphys halli, Reithrodon auritus y Euneomys chinchilloides) y otras afines al desierto del Monte (p.ej. Galea leucoblephara, Akodon iniscatus y Calomys musculinus), en contraste con las muestras actuales donde principalmente se hallaron especies patagónicas, señalando un paleoambiente más árido y cálido que el actual.

          Translated abstract

          This paper describes micromammal samples from two archaeological sites spanning a period from 3,800 yr. BP until the 20th century, and located in the middle basin of the river Grande, in the south-west of the Mendoza Province (Cueva de Luna and Alero Puesto Carrasco). Also, the taphonomic and paleoenvironmental conditions are assessed. The recording of light and moderate digestive traces indicates that the micromammals of both samples were deposited by strigiform birds, possibly Tyto alba. This contrasts with the model of intensification of resources proposedfor the hunter-gatherers who inhabited southern Mendoza toward 2,000 yr. BP. The archaeofaunistic assemblages showed some taxonomic stability, including Patagonian species (e.g., Lestodelphys halli, Reithrodon auritus and Euneomys chinchilloides) and others associated with the Monte desert (e.g., Galea leucoblephara, Akodon iniscatus and Calomys musculinus), contrary to recent samples, which mainly found Patagonian species, suggesting a more arid and warm palaeonvironment than recent times.
