The production of large elongated blanks in the ancient occupations of Serranópolis, Central Brazil
The region of Serranópolis (Goiás, Brazil) is inserted in the area defined as Central Brazil. The studies of the lithic industries of the ancient levels of the archaeological site GO-JA-03, dated at 9765 ± 75 BP, indicate a production of large elongated flakes (the longer are 20 cm), produced in a h...

| Sumario: | The region of Serranópolis (Goiás, Brazil) is inserted in the area defined as Central Brazil. The studies of the lithic industries of the ancient levels of the archaeological site GO-JA-03, dated at 9765 ± 75 BP, indicate a production of large elongated flakes (the longer are 20 cm), produced in a highly silicified local sandstone. The flakes were used as blanks to produce very thin unifacial tools and other thicker flat-convex section unifacial tools. The objective of this work is to realize a technological analysis based on the concept of Chaïne Opératoire and focoused on the tools’ production phases, emphasizing the technological stigmas that indicate the techniques used during the initial phases, in order to obtain these blanks. The results of the technological analysis are compared to an experimental program and point out the use of two main techniques: organic direct percussion and soft stone tangential percussion - uncommon in the débitage stage in the lithic Brazilian industries. The verification of the use of these techniques in this phase of knapping is consistent with the high degree of savoir-faire observed in the lithic industries of the ancient occupations of the site. |
