Resumen
Durante las primeras excavaciones realizadas en el Parador QB (Parque Nacional Islote Lobos, costa Rionegrina) se recuperaron huesos de aves en los conjuntos zooarqueológicos. Al igual que en otras localidades arqueológicas del litoral Nordpatagónico, la representación de este taxón es escasa, pero con un muy buen estado de preservación. Con el objetivo de explorar el papel de las aves en la subsistencia de las sociedades cazadoras-recolectoras que ocuparon este litoral durante el Holoceno tardío, desarrollamos un estudio tafonómico para establecer si la depositación de sus huesos se debe a la acción antrópica o a causas naturales. La evaluación tafonómica de los restos avifaunísticos es fundamental dado que actualmente existen áreas de nidificación de diversas aves marino-costeras próximas a los sitios arqueológicos, por lo que sería factible la “contaminación ósea” -o mezcla de huesos naturales y materiales arqueológicos. Se concluye que los huesos de aves de los tres loci tienen trayectorias tafonómicas similares, mientras que la mezcla de restos óseos de diferente origen se registró principalmente en el caso de los pingüinos de Magallanes. Por último señalar que, aunque las aves no son tan abundantes, tuvieron un lugar importante en el repertorio de presas de los cazadores-recolectores de la región.
During the first excavations carried out at the Parador QB (Islote Lobos National Park, Rio Negro coast), bird bones were recovered in the zooarchaeological assemblages. As in other archaeological localities on the North Patagonian coast, the representation of this taxon is scarce, although the bones present a good state of preservation. With the aim of exploring the role of birds in the subsistence of the hunter-gatherer societies that occupied this coastline during the Late Holocene, a taphonomic study was developed to establish whether the deposition of bird bones was due to anthropogenic action or to natural causes. The taphonomic evaluation of the avifauna remains is essential given that currently there are nesting areas of various marine-coastal birds close to the archaeological sites, so that “bone contamination,” or the mixing of natural bones and archaeological materials, can result. It is concluded that bird bones from the three loci have similar taphonomic trajectories, while modern bones mixed with the archaeological materials were mainly of Magellanic penguins. Finally, it should be noted that, although bird bones are not abundant, birds had an important place in the prey repertoire of the hunter-gatherers of the region.
