TL;DR: Sambaqui is a term for cultural deposits of varying size and stratigraphy in which shell is a major constituent, undoubtedly encompassing accumulations with a range of functions and origins.

TL;DR: Bulk collagen carbon and nitrogen isotopic analysis of 82 human individuals from mid to late Holocene Brazilian archaeological sites reveal an adequate protein incorporation and, on the coast, the continuation in subsistence strategies based on the exploitation of aquatic resources despite the introduction of pottery and domesticated plant foods.

TL;DR: A reuniao de dados originais e de revisoes da literatura, numa abordagem multidisciplinar praticamente inedita na arqueologia brasileira, forneceu subsidios for um melhor conhecimento da sociedade sambaquieira as discussed by the authors.

TL;DR: In this article, sedimentary facies analysis was adapted for description, sampling, and interpretation of shell mound complex and repetitive archaeostratigraphic successions, and preliminary results showed that depositional attributes are a reliable base for archaeofacies identification in the field.
