Summary

This is an abstract from the "Beyond Pre-Clovis: Human Occupations in the Americas during the Last Glacial Maximum and the Perpetual Debate" session, at the 90th annual meeting of the Society for American Archaeology.

The objective of this communication is twofold: to share the basic heuristic applied to the study of lithic materials of low archaeological visibility and to present some of the results obtained. We applied the Techno-Functional Approach to investigate the lithic materials collected in the C7α sedimentary facies of the Vale da Pedra Furada site, located in the PARNA Serra da Capivara (PI). This facies was dated to approximately 24,000 years BP and is part of a long occupational column distributed in thirteen sedimentary layers that, to date, extends chronologically between 41,000 years BP and 7,000 years BP. The analysis of the materials evidenced allowed us to hypothesize that they are the archaeological remains of a coherent, cohesive, and consistent "Knapping Structure". We characterize these remains as evidence of aggregation or "protocooperation" between two production Principles: Affordance and Debitage (Concept C). These principles governed different groups of chaînes opératoires that were aimed at obtaining lithic tools (n:471) fundamentally equivalent in terms of their functional potential. The main components recognized among the technotypes that make up the Panoply of Tools are derived from the functionalization processes of the types Exteriorization (n: 173), "All Edge" (n: 166) and Interiorization (n: 76).
