STOESSEL, Luciana; MARTINEZ, Gustavo  and  CONSTENLA, Diana. Preliminary analysis of fatty acids recovered from archaeological pottery of the lower course of the Colorado River (North-Eastern Patagonia): Contributions to the hunter-gatherers subsistence patterns. Magallania [online]. 2015, vol.43, n.1, pp.231-249. ISSN 0718-2244.

This paper presents the preliminary results obtained of the analysis of fatty acids recovered from pottery sherds from three archaeological sites of the lower course of the Colorado River (North-eastern Patagonia, Argentina). These sites correspond chronologically to the late Holocene, both initial (ca. 3.000-1.000 years BP) as final (ca. 1.000-250 years BP) periods. The information obtained suggests cooking of large herbivores and possibly plants and/or bone marrow, as well as the presence of marine resources, most likely fish. In general terms, these results are consistent with the main trends described in the subsistence model proposed for the area, from zooarchaeological evidence and information provided by stable isotopes from bone human remains. In addition, results of fatty acids allowed inferring aspects related to the exploitation and consumption of certain resources (i.e., fish) at specific places of landscape (Atlantic coast) as well as mobility strategies by late Holocene hunter-gatherer groups.

Keywords : fatty acids; Northern Patagonia; subsistence; late Holocene.
