Description
Punta María 2 es un sitio emplazado en la costa atlántica de Tierra del Fuego donde se recuperó el conjunto zooarqueológico de pinnípedos más abundante de dicho litoral hasta la fecha. En este trabajo presentamos la revisión de una submuestra de restos de otáridos sobre la que se desarrollan nuevos análisis: osteométricos, de identificación de rasgos diagnósticos y cronograma de fusión. Así, a partir de la construcción de datos más ajustados de especies, sexo y edad, discutimos interpretaciones previas. Nuestros resultados señalan que las presas habrían sido mayormente individuos subadultos entre uno y tres años de edad, con predominio de Otaria flavescens sobre Arctocephalus australis, mientras que en los adultos la representación de especies fue más equitativa, indicando un uso oportunístico de los lobos marinos. Finalmente, se señala que el empleo conjunto de diferentes abordajes metodológicos resulta muy adecuado y promisorio para el análisis zooarqueológico de estos animales.
Punta María 2 is a site located on the Atlantic coast of Tierra del Fuego, which presents the most abundant zooarchaeological assemblage of pinnipeds reported for that coast. In this paper, we review a subsample of this otariid assemblage in order to develop new osteometric analysis, as well as the identification of diagnostic features and the epiphyseal fusion data. Thus, from the construction of more adjusted datasets of species, sex and age, we discuss previous interpretations. Our results show that the preys were mostly subadult individuals between one and three years of age, with a predominance of Otaria flavescens over Arctocephalus australis, while in adults the representation of species was more balanced, indicating an opportunistic encounter hunting. Finally, we would like to note that the joint use of different methodological approaches is extremely adequate and promising for the zooarchaeological analysis of these animals.
