CIAMPAGNA, María Laura; AMBRUSTOLO, Pablo  and  ZUBIMENDI, Miguel Ángel. Estudios antracológicos en abrigos rocosos de la costa norte de Santa Cruz (Patagonia, Argentina): análisis de los sitios El Oriental y Alero 4. Intersecciones antropol.

In this paper analyzes performed on anthracological remains recovered on hearths from El Oriental and Alero 4 rock shelters (North Coast of Santa Cruz, Patagonia Argentina) are presented. We discuss the functionality of the combustion areas on each site considering its archaeological association and taxa identified. A comparative study was made based on the relative density of charcoals and the characteristics of the taxa registered on each hearth. The general trends identified are assessed regarding the discussions on the home range of the hunter gatherers populations who use the rock shelters during the middle and late Holocene. In order to identify anthracological macro remains, a reference collection was performed considering histological sections, density logs of wood available in the area and an experimental carbonization. On the analyzed hearths, taxa of low, medium and high density were identified, such as Senecio/Baccharis, Adesmia, Discaria, cf. Lycium, Lycium, Schinus, Berberis y Atriplex/Suaeda. Results contribute to discuss the functionality of rock shelters in the NCSC and also in a general way, in Patagonia; moreover, constitute an advance in the knowledge of the way that some archaeological sites were reoccupied during different chronological times.
