Current research on the coastal shellmounds (or sambaquis) in Brazil considers them structures intentionally constructed from complex cultural units, a continuous process of sedentarization and demographic densification, which have expanded throughout the Brazilian coast between at least seven thousand and fifteen hundred years ago. After this period of shellmounds domination in coastal ecosystems, a process of change in the configuration of the sites occurred, marked by the presence of pottery in more recent layers of the shellmounds and by the appearance of new late settlements. Such transformations are interpreted as the beginning of contact between the interior peoples and the coastal populations. This master's research sought to deepen the knowledge obtained about the Galheta IV ceramic site (dating from 1256-1031 and 690-530 cal BP) during the Sambaquis e Paisagem project, from a zooarchaeological perspective, and to bring new data that contribute to the understanding of the discontinuity processes of the construction of shellmounds sites in the south coast of Santa Catarina. Analyzes contemplated intra-site areas in an attempt to understand their relational and spatial contextualization. The results identified zooarchaeological vestiges acting as funerary accompaniments. A concentration of fauna remains in a specific area of the archaeological site, associated to a large number of concretions, point to a high processing and consumption of vertebrates related to the funerary context of the site. The significant presence of large marine species, such as pinnipeds, sharks, and cetaceans, added to the results of previously developed isotopic analyzes, inaugurates a panorama that differs from other studies of fauna in coastal sites developed until then, in which fish are protein sources predominant in the diet of preceramic and ceramic populations. These marine animals of high trophic chain, in addition to fish, birds and sea turtles, demonstrate a continuity and intensification of the fishing practices developed by sambaquis people, in an adaptation for the capture of resources near the rocky coast and the open sea.
