Summary

The research our teams are conducting in the parc of Capivara in Brazil since 2008 lead to reveal 6 new Pleistocene archaeological sequences . The sites are all located within a 20 km area and stem from different sedimentary and topographic environments including: open air, rock shelter, cave at the bottom of cuesta or in karst. Each of the sites shows different sedimentary sequences, including different archeological horizons and different typo-technical compositions. The dating that we have obtained by crossing C14, TL and OSL data lead us to identify accurately each of these archaeological sites, hence permitting to attempt a comparative approach with the major climate changes observed during the isotopic states 2 and 3. Based on this study, at a large scale reading, there is no evidence of a correlation between major climate changes and periods of occupation. Nevertheless, we can notice a concordance of vacancy within the group of investigated sites. Technically, those vacancy periods correspond to clear technical changes. All those observations reflect the fact that our region of research witnessed different Pleistocene occupations beginning from isotopic states 2 and 3.
