    Este artigo apresenta o estudo tecnológico das coleções líticas de três sítios arqueológicos localizados próximos à Foz do rio Chapecó (Alto Alegre 3, Linha Policial 1 e Linha Policial 3), nos estados de Santa Catarina e Rio Grande do Sul, datadas do Holoceno antigo e associadas aos materiais arqueológicos da Tradição Umbu. Apresentaremos um esquema operatório de produção de lâmina, descrito pela primeira vez na pré-história brasileira. Apesar da ausência de núcleos, pela análise das lâminas observamos os métodos e as técnicas de produção das mesmas e os seus potenciais funcionais. Com este estudo afirmamos a necessidade de maior desenvolvimento de estudos tecnológicos detalhados para melhor entendermos o povoamento do Brasil em toda a sua complexidade.This article presents the technological study of lithic collections fromthree archaeological sites located near the at the mouth of the Chapecó river (AltoAlegre 3, Linha Policial 1 and Linha Policial 3), in the states of Santa Catarina andRio Grande do Sul, dated to the early Holocene and associated with archaeologicalmaterials of the Umbu Tradition. We will present the operational schemes of bladeproduction, described for the first time for Brazilian prehistory. Despite the lack ofcores, analysis of the blades has established the methods and techniques for theirproduction and the functional potential of blade blanks. With this study, we affirmthe necessity of developing detailed technological analyses to understand the settling of South America in all its complexit

    International audienceThe date of the first settlement of the Americas remains a contentious subject. Previous claimsfor very early occupation at Pedra Furada in Brazil were not universally accepted (see Meltzer et al. 1994). New work at therockshelter of Boqueirao da Pedra Furada and at the nearby open-air site of Vale da Pedra Furada have however produced new evidencefor human occupation extending back more than 20 000 years. The argument is supported by a series of 14^{14}C and OSL dates, and bytechnical analysis of the stone tool assemblage. The authors conclude that the currently accepted narrative of human settlement inSouth America will have to be re-thought
