Subsistence strategies during the Gravettian in the rock shelter of La Viña (Asturias, N Spain)

Abstract

The rock shelter of La Viña, located on the northern Atlantic coast of the Iberian Peninsula, contains a rich archaeological sequence dated from the Mousterian to the Magdalenian. This site preserves an extended Gravettian occupation where a diversified assemblage of fauna, lithic and bone tools has been attested. In this paper, we undertake the archaeozoological and taphonomic study of the macromammals found in the Gravettian levels X and IX of the Western Sector, recovered during the campaigns directed by Fortea between 1987 and 1992. The taphonomy indicates a high presence of fire-altered bone elements and butchery marks related to ungulate skinning and disarticulation activities, with a low presence of carnivore modifications, being 'Cervus elaphus', followed by 'Rupicapra rupicapra' and 'Capra pyrenaica' the most common taxa, therefore confirming the anthropogenic origin of the bone assemblage. Given the high fragmentation of the infantile remains identified, a biomolecular study by Zooarchaeology by Mass Spectrometry (ZooMS) was carried out to increase the taxonomic data and unravel the hunting strategies and site seasonality. Proteomic results revealed a high presence of newborn red deer and ibex, thus suggesting females herd captures during late spring/early summer.
