Human mobility on the Brazilian coast: an analysis of strontium isotopes in archaeological human remains from Forte Marechal Luz Sambaqui

This study investigated strontium isotopes in the dental enamel of 32 human skeletons from Forte Marechal Luz sambaqui (shellmound), Santa Catarina, Brazil, aiming at identifying local and non-local individuals. The archeological site presents pot sherds in the uppermost archeological layers. Dental...

F Santos, Ricardo V Rodrigues-Carvalho, Claudia Brazil human mobility isotopes prehistory shellmounds strontium Brasil mobilidade humana isótopos pré-história sambaqui estrôncio This study investigated strontium isotopes in the dental enamel of 32 human skeletons from Forte Marechal Luz sambaqui (shellmound), Santa Catarina, Brazil, aiming at identifying local and non-local individuals. The archeological site presents pot sherds in the uppermost archeological layers. Dental enamel was also examined from specimens of terrestrial fauna (87Sr/86Sr = 0. 71046 to 0. 71273) and marine fauna (87Sr/86Sr = 0. 70917). The 87Sr/86Sr isotope ratio for individuals classified as locals ranged from 0. 70905 to 0. 71064 and was closer to the isotope ratio of the seawater than to the ratio of the terrestrial fauna, indicating a strong influence of marine strontium on the inhabitants of this sambaqui. The results indicate the existence of three non-local individuals (87Sr/86Sr = 0. 70761 to 0. 70835), buried in both the level without pottery and the layer with pottery, possibly originated from the Santa Catarina Plateau, close to the municipality of Lages, or from the Curitiba Plateau. The occurrence of a slight difference between the isotope ratios of local individuals buried in the archeological layer without pottery, when compared to those in the layer with pottery, suggests a possible change in dietary patterns between these two moments in the site's occupation O presente estudo investigou isótopos de estrôncio em esmalte dentário de 32 remanescentes humanos do sambaqui do Forte Marechal Luz, Santa Catarina, Brasil, com o objetivo de identificar indivíduos locais e não-locais. O sítio arqueológico apresenta fragmentos de cerâmica em suas camadas arqueológicas mais recentes. Além das amostras humanas, foram analisadas amostras de esmalte dentário de espécimes de fauna terrestre (87Sr/86Sr = 0,71046 a 0,71273) e fauna marinha (87Sr/86Sr = 0,70917). A razão 87Sr/86Sr dos indivíduos classificados como locais variou de 0,70905 a 0,71064, sendo próxima a razão de estrôncio existente nos oceanos e distante da razão obtida para a fauna terrestre do mesmo sítio, indicando uma influência marinha na origem do estrôncio dos habitantes desse sambaqui. Foram identificados de três indivíduos não locais (87Sr/86Sr = 0,70761 a 0,70835), sepultados em ambas camadas arqueológicas sem evidência e com evidência de cerâmica. Estes indivíduos podem ter origem no planalto catarinense, no entorno do município de Lages, ou do planalto curitibano. A ocorrência de uma pequena diferença entre as razões isotópicas dos indivíduos locais sepultados nas camadas sem evidência de cerâmica, daqueles sepultados nas camadas ceramistas, sugere a possibilidade de uma mudança nos padrões de alimentação entre esses dois momentos de ocupação do sítio 2017-12-07T04:56:00Z 2017-12-07T04:56:00Z 2011 Artigo An.
