Resumen:
This work presents the techno-morphological and taphonomic study of the cores from the open-air site San Genaro 3 ? 4, located on the southern coast of San Sebastián Bay (Tierra de Fuego, Argentina). This research is part of a regional project aimed at the study of late Holocene coastal occupations of hunter-gatherers in northern Grande Island of Tierra de Fuego. The assemblages were collected from aeolian deflation hollows in the longitudinal sand dunes of the Chorrillos archaeological locality, a high energy sedimentary environment affected by strong winds. Taphonomic assessment reveals that aeolian abrasion of artifact surfaces is a reliable indicator for lithic assemblage exposure and stability thereof. Furthermore, different abrasion degrees show diverse flaking events and subsequent configurations. After techno-morphological and taphonomic analyses, several questions are posed about the recurrence of occupations in the locality, criteria of blank selection, the strategy of volume management, artifact versatility and, ultimately, the functionality of the place related to the marine resources exploitation.
