The paleoenvironment of southeastern São Paulo: contributions from Itapeva shelter to a discussion on anthropic and natural insertion

Paleoclimate reconstitution for the state of São Paulo results from past and ongoing research efforts in palynology, anthracology, stable isotope studies. In cases such as southern Paulo, however, researchers are required to extrapolate data states Paraná, Santa Catarina, Rio Grande do Sul comparisons. Phytoliths seeds were collected sediments retrieved excavation units D18 G6 at Abrigo de Itapeva [Itapeva Shelter] archeological site analyzed. Seed indicate that Ocotea (Lauraceae) is present initial levels, whereas Syagrus romanzoffiana predominates all other stratigraphic levels. The former a species Atlantic Forest occurs Araucaria Forests; latter palm found southeastern Brazil. analysis reveals change drier climate with grassland vegetation woody forest later periods shelter occupation. As such, types occur base levels up level seven, dating 5,510 cal BP 730 BP. Conversely, seven surface dated 560 BP, we see linked proliferation which may presence Jê groups study area, thus corroborating studies on possible anthropization forests 1,000
