“…It is located in the southwest of Mendoza province, in the high valley of Atuel river, near the mouth of Arroyo Malo in that river and three km from the Laguna El Sosneado (Figure 1). From a phytogeographic point of view, the AMA-3 site is emplaced in the Patagonian province (sensu Cabrera, 1976). This unit is characterized by a cold and dry weather, with strong winds from the Pacific anticyclone and winter precipitations of nival type (600 to 1000 mm).…”

“…This unit is characterized by a cold and dry weather, with strong winds from the Pacific anticyclone and winter precipitations of nival type (600 to 1000 mm). The dominant vegetation is the shrub and herbaceous steppes, and cordilleran meadows, which are developed on basaltic, sandy, stony and poor in organic matter soils (Cabrera, 1976). The community of steppes is mainly dominated by: Mulinum spinosum, Ephedra ochreata, Chuquiraga rosulata and species of the genus Azorella, Adesmia, Poa, Senecio and Maihuenia (Cabrera, 1976).…”

The AMA-3 site is near the ecotone of the Patagonian province with the Altoandina phytogeographic province (> 3000 m asl, sensu Cabrera, 1976), the latter being characterized for having a cold weather with a winter precipitation regime (mainly as snowfall), which come from the Pacific anticyclone.…”

The chamaephytes and shrubs steppes predominate in this province, and the cordilleran meadows and semi-desert of lichens are common, especially the genera Adesmia, Cassia, Oxalis, Verbena and Mulinum (Cabrera, 1976).…”

Se identificaron taxonómicamente restos de micromamíferos provenientes del sitio arqueológico Arroyo Malo-3 (AMA-3, 34º51’18’’S, 69º53’00’’O; suroeste de Mendoza, Argentina) y se analizaron aspectos tafonómicos y paleoambientales. Los restos de micromamíferos (NISP = 7239, MNE= 7211, MNI = 730) fueron recuperados de unidades correspondientes al Holoceno (Unidad III = 8900-3810 años 14C AP; Unidad II = 3810-2200 años 14C AP; Unidad I = 2200-~100 años 14C AP). Las evidencias tafonómicas tales como egagrópilas preservadas en la estratigrafía, patrones de abundancia relativas de partes esqueletales y restos con marcas de digestión moderada y fuerte, indican que el principal agente acumulador de los conjuntos de micromamíferos recuperados de AMA-3 podrían haber sido aves Accipitriformes, posiblemente Geranoaetus melanoleucus (águila mora) o Buteo polyosoma (aguilucho común). El escaso registro de huesos meteorizados, la ausencia de marcas de pisoteo, raíces, corrosión sedimentaria y transporte hídrico, junto a la evidencia de numerosos especímenes con impresiones de óxido de manganeso, sugieren que los mismos tuvieron un enterramiento rápido y buena preservación, aunque con altos niveles de humedad. Los conjuntos de micromamíferos de AMA-3 mostraron una marcada estabilidad taxonómica, con algunos cambios menores hacia el Holoceno tardío. El cambio mayor ocurrió en los conjuntos actuales cercanos al sitio, señalando un aumento de la arbustización atribuible al impacto antrópico producido por el ganado doméstico, afianzado en el sur de Mendoza desde el siglo XIX. La información tafonómica y paleoambiental presentada provee una estructura relevante para optimizar los estudios biogeográficos y de sistemas de subsistencia de los cazadores y recolectores del sur de Mendoza durante el Holoceno.
