NATURAL DISTRIBUTION OF BONE REMAINS IN THE INTERTIDAL ZONE FROM THE SOUTH OF TIERRA DEL FUEGO: TAPHONOMIC OBSERVATIONS AND ARCHAEOLOGICAL IMPLICATIONS

In this paper, the natural distribution pattern of modern bone remains in different parts of the Moat Bay coastal area is analyzed. The purpose of this analysis is to assess the areas with a higher probability of bone remains accumulation and dispersion, and to generate expectations about the integrity of archaeological sites. Additionally, the natural modifications that occur on the cortical surface of bones are evaluated. Results show that intertidal zone dynamics has a dissimilar effect in bone assemblage formation, and that these processes have different impact level depending on location and coastal landform type. Furthermore, different taphonomic trajectories for birds and mammals were identified. Results allow predicting the integrity level of the sites located in the environmental contexts under study and provide valuable decision-making tools for archaeological projects in this region.
