Diversité culturelle des peuplements pionniers du Sud du Brésil à l’Holocène initial

The variety of South American lithic industries in the Early Holocene indicates that the settlement processes were characterized by cultural diversification and adaptive flexibility. In the present article, we will analyze the bifacial lithic industries of southern Brazil that include projectile points in their repertoire of instruments, through a comparative study between the results of research in the hydrographic regions of Uruguay River and Lake Guaíba. Our objective is to problematize issues about the construction of cultural territories in the process of initial settlement of the South American Cone through the analysis of technical systems.
