Holocene molluscs from Rio de Janeiro state coast, Brazil

Abstract

A list of marine species of bivalves and gastropods found in seventy archeological sites of the shellmoundtype from Rio de Janeiro state was produced, based on the archeological material deposited in the collections of MuseuNacional (Rio de Janeiro, RJ), Instituto de Arqueologia Brasileira (Belford Roxo, RJ) and Museu do Sambaqui da Tarioba(Rio das Ostras, RJ). A total of 124 taxa were identified, of which 65 bivalves and 59 gastropods. The data retrieved from theshellmounds indicate stability of the composition patterns of mollusc biodiversity on the Rio de Janeiro state coast, at leastin the period between 8,000 and 2,000 years B.P. The listing presented may be useful as a reference inventory for researchpertaining to biological invasions, biogeography, conservation and management.
