چکیده انگلیسی
In southern Patagonia, the occurrence of large seabird nesting colonies condition the features of the regional bone record, which is characterized by a large amount of bird remains, despite their small body size. Bird and mammal bones have remarkably different taphonomic histories in this region: mammal remains are less damaged by carnivores and resist weathering for long periods, whereas bird bones show a greater initial destruction by carnivore activities and faster deterioration by weathering. A comparison of these results with results from research conducted in several African parks (particularly Amboseli) shows that differences in both records are mainly due to differences in community composition and predator-prey dynamics in both ecosystems. Furthermore, while in both ecosystems bird bones weather more rapidly than mammal bones, destruction by this process is more rapid in Patagonia. Overall, the analysis reinforces the need to generate specific models to understand taphonomic histories of archaeofaunal assemblages from Patagonia.
