The Late Pleistocene/Early Holocene archaeological record in Brazil: A geo-referenced database

摘要

Between 13,000 and 8000 ~(14)C BP, eastern South America was settled by a stable and diversified population of hunter-gatherers. Archaeological excavation in the past twenty years has yielded increasingly consistent evidence of occupation in different regions of Brazil since the end of the Pleistocene, with dates at least contemporary to the Clovis Horizon in North America. This is addressed by documenting and analysing the quantity, quality and distribution of archaeological ~(14)C dates from Brazil during this period. A total of 277 dates from 90 sites are tabulated, mapped, and included in the analysis. During the Late Pleistocene there was a pioneer phase of human colonization, -with dispersal inland through the major river systems. Subsequently, the Early Holocene saw the first phase of established settlement of Brazil's interior. There seems to be an archaeological threshold reached at ca. 10,500 years ~(14)C BP: numbers of sites increase, there is evidence of settlement of all major biomes, and there is clear evidence of inter-regional cultural diversity.
