RESUMO:

The Northeast region of Brazil is well known for the abundance of fossiliferous sites with the presence of the Pleistocene megafauna, mainly in tank deposits. There is a great diversity of works on tanks in Bahia that deal with taxonomic aspects, while taphonomic studies are still scarce. The absence or presence of taphonomic processes are crucial to estimate the quality of the fossil record, so it is necessary to identify signatures of these processes in the deposits, in order to better understand them and enrich the reconstructions of the paleoenvironment. Therefore, this work aimed to describe and interpret taphonomic signatures in fossils from the Lagoa Escura tank in the municipality of Santaluz, Bahia, in order to improve the understanding of the preservation of fossils in natural tanks and infer paleoenvironmental aspects, contributing to the understanding of northeastern Brazilian paleoenvironment during the Quaternary. The fossiliferous accumulation of Lagoa Escura is very diverse taxonomically, recording about seven taxa of fossil mammals. The abundance of E. laurillardi in the accumulation is a result of the great abundance that this species had in the paleocommunity and how its bones are resistant. The Lagoa Escura tank thanatocenosis is a para-autochthonous assemblage that in some part experienced a short period of sub-air exposure prior to burial and short-distance transport.
