Cazadores-recolectores del Holoceno medio en las sierras de Tandilia oriental (Argentina)

Cazadores-recolectores del Holoceno medio en las sierras de Tandilia oriental (Argentina) is the result of doctoral research on the hunter-gatherer groups that inhabited the eastern Tandilia mountain range (Argentina) during the mid-Holocene period, generating new knowledge on aspects related to lithic technology, raw material management and mobility strategies. This study analysed lithic tools recovered from several archaeological sites excavated in caves and rock shelters, specifically between the present-day localities of Balcarce and Mar del Plata.The main results show that hunter-gatherer groups of this period combined two mobility strategies. On the one hand, the mountain range occupations reflect a high logistical mobility aimed mainly at hunting guanacos and pampas deer, where caves and rock shelters were used as temporary shelters while away from residential camps. On the other hand, the integration of these results within the framework of the Pampa Humeda sub-region suggests that the residential groups of this period were able to carry out annual or seasonal movements within a regional radius, with mobility circuits that included different ecosystems (coast, grassland plain and mountain range) and took advantage of a wide variety of terrestrial and marine resources available at different times of the year.
