TECHNOLOGICAL VARIABILITY IN THE ANCIENT HOLOCENE IN THE CENTRAL PLATEAU OF BRAZIL AND BORDER SOUTHWESTERN BRAZIL WITH URUGUAY
We’ll present reflections about the technological variability of two regions of Brazil, the Central Plateau and the southern state of Rio Grande do Sul. Both are dated from the ancient Holocene and the results comes from techno-functional analysis applied in lithic materials evidenced in sites of these regions.
The Central Plateau is characterized by the Itaparica Techno-complex, composed of instruments with silhouette easily identifiable. The technical design allows a standardized hafting and organization of different functional parts. The defined spatial distribution of this material and its rupture with the Middle Holocene indicates that it is a technical phenomenon that no exist in other sites in South America.
In the area of southwestern border of Brazil with Uruguay, archaeological sites in surface and stratigraphy present a significant technical diversity. Technical systems of production were evidenced, and for each of the modes (façonnage and debitage) there are different predetermined blanks that correspond or not to specific tools. We present technological diversity witnessed in different areas and specific period, indicating multiple technical behavior where a single model is not enough to explain the occupations.
