Resumen
Diversas especies de roedores se encuentran con frecuencia en los sitios arqueológicos del norte de Tierra del Fuego. Sin embargo, discriminar las vías de incorporación en los contextos arqueofaunísticos y su potencialidad resulta una tarea ardua. La identificación de aquellos restos que ingresaron por acción antrópica o por agentes naturales resulta necesaria para poder inferir el rol que tuvieron en la subsistencia humana. En este trabajo se estudian los restos de roedores del sitio arqueológico Las Vueltas 1 (Isla Grande de Tierra del Fuego, Argentina), donde representan el segundo taxón más abundante en la muestra. Se identificaron un total de 2191 elementos esqueletarios; 1488 corresponden al caviomorfo Ctenomys magellanicus y 703 a representantes de la familia Cricetidae, con al menos 4 especies. La interpretación tafonómica efectuada sugiere un origen múltiple; buena parte del material parece haber ingresado por la acción acumuladora de aves rapaces y cánidos y también por incorporación natural a través de muerte en madrigueras. No obstante y aunque en menor grado, hay evidencias de consumo y descarte antrópico en C. magellanicus.
It is frequent to find the remains of several rodent species among the many archaeological sites of Northern Tierra del Fuego. However, the taphonomic interpretation of rodents is a complex issue, given that it is necessary to identify if these were incorporated into the archaeological assemblages through anthropic or natural action or agents. Yet, the identification of those assemblages that accumulated through human action or due to natural agents is an important issue given that only then we can infer the role that rodents had in human subsistence. In this article, we study rodent remains recovered from the archaeological site of Las Vueltas 1 (Isla Grande de Tierra del Fuego, Argentina); here rodents represented the second most common taxon present in the assemblage. A total of 2191 skeletal elements were recorded; 1488 remains belonged to the caviomorph, Ctenomys magellanicus, while 703 specimens belonged to at least four Cricetidae species. From a taphonomic perspective, a large number of the remains would have entered the archaeological assemblage through actions by raptors, carnivores, and as a result of natural death in burrows. Nevertheless, although to a lesser extent, there is also evidence of human consump- tion and discard of C. magellanicus.
