Several Paleoindian sites in Brazil, especially in the Southern and Central regions of the country, are known due to decades of excavations on those areas since the 1960's. However, few systematic analysis of the material culture of those Paleoindian sites have been done until this day. Archaeological literature from Brazil usually classifies only two archaeological cultures for the Paleoindian period in Eastern South America - the "Itaparica Tradition" and the "Umbu Tradition", both dating between 13,000 and (at least) 7000 years ago. Few research has been done in order to verify if the archaeological assemblages of these two archaeological cultures are culturally homogeneous and how they evolved. This project goal is to understand the real cultural evolution and diversity of Paleoindian cultures that are probably being obliterated by the Itaparica-Umbu model to better understand their geographical and chronological distribution, focusing in lithic assemblages from the Southern region of Brazil, and also from Minas Gerais, Mato Grosso do Sul and São Paulo states. The comprehension of the real cultural evolution and diversity of paleoindian groups by analyzing the main features of their lithic vestiges will provide means for understanding the relationship between contemporaneous paleoindian groups from Brazil and other South American regions, as well as possible ancestry and descendent connections with earlier and later cultures.
