The first settlers on the northern coast of Espírito Santo: a new approach to shell mound (sambaqui) archaeology

Abstract The shell mounds (sambaquis) on the coast of Espírito Santo have received little attention in archaeological research. Despite being known to scholars since the end of the nineteenth century, shell mounds were recurrently considered marginal to the cultural developments in the neighboring state of Rio de Janeiro. Scarce information on the contents of the sites and the lack of well-referenced 14C dating prevented a complete understanding of the time-depth and evolution of pre-colonial settlement on this fragment of the Brazilian coast. This paper introduces the aims and preliminary results of renewed archaeological research on the shell mounds of the northern coast of Espírito Santo, in the municipality of Linhares. Two shell mounds have been excavated thus far, pushing the record of human presence on the coast back by almost 2000 years. The new research follows a standardized method of excavation specially designed for initial characterization of shell mound deposits; this method involves creating a digital database and incorporating computerized methods for excavation management. Signs of human presence were seen along the northern coast before the Holocene maximum transgression (Suruaca site, dated c. 6800 cal. BP), when mangroves, restingas, and the Atlantic rainforest comprised the coastal environment.
