Resumen:
Rheidae eggshell fragments are ubiquitous in north Patagonian archaeological sites, suggesting that this source was important for prehispanic human populations in the region. Here we present temporal and spatial trends in carbon (?13C) and oxygen (?18O) values of eggshells (n=232) from north Patagonia to evaluate potential shifts in past environmental conditions. The eggshell samples are derived from 20 archaeological sites located in a variety of environmental contexts in southern Mendoza province and date to ~5000-500 ypb.
