Corondó: palaeoenvironmental reconstruction and palaeoethnobotanical considerations in a probable locus of early plant cultivation (south-eastern Brazil)

Abstract

The site of Corondó, situated in Campos Novos, in the São Pedro D'Aldeia municipe (Rio de Janeiro State, Brazil), was dated between c. 4000 and 3000 years BP. The high prevalence of dental caries in its population suggests that it might have been a locus of plant cultivation, a hypothesis supported by the presence of diverse plant remains and by the high frequency of grinding artefacts at this site. Anthracological analysis aimed to identify the environment of the site. The charcoal spectrum suggests that it was situated in a restinga forest, near to the Atlantic forest and with the presence of mangrove and open restinga in the environment. Firewood supply was probably obtained by the random gathering of dead wood. The combination of anthracological results with data provided by archaeological and bioanthropological research indicated that the population which constructed this site (1) had a relatively stable sociocultural system; (2) carried out a range of individual activities that remained constant throughout the occupation period; (3) lived in a relatively stable environment.
