Shared lithic raw materials have been key elements when considering the interconnections among archaeological contexts from distant places. A relationship based on similar archaeological assemblages and physical features of their settings has already been proposed for the central-east portion of the Tandilia Range (Buenos Aires) and Somuncurá Plateau (Río Negro). Particularly, this correlation has been established between Cerro El Sombrero Cima and Amigo Oeste, both outstanding sites with early settlers evidences. In this presentation we analyze a singular tool found at Cueva Zoro, a spatially and chronologically related site to Cerro El Sombrero, manufactured on reddish and ocher-colored chert. No flakes, cores or other tools on the same rock have been found so far at this site or other sites with similar chronology in the micro-region. This rock also has not been recorded among assemblages assigned to the Middle and Late Holocene. The source for this raw material most probably lies outside the region. In contrast, this rock is found among different types of tools and flakes at Amigo Oeste and nearby sites in the Somuncurá Plateau. Reddish, brown and ocher-colored chert outcrop in the Talagapa Creek basin. Since no petrographic analyses are possible, this presentation is based on a first approach to these lithic materials through a visual comparison.
