| Resumo: | Abstract: The study of the mollusks from the Chalcolithic and the early Bronze age (III Millennium BC) contexts discovered in Chibanes revealed the presence of 19 bivalves and 6 gastropods species from estuarine/maritime environment. The Ruditapes decussatus (clams) greatly predominates in all of the identified layers, followed by Solen Marginatus (razor clams) with a significant difference. In the several layers a great variety of mollusks was observed with an average of 11 to 13 species per layer. The most abundant species indicate the exploitation of the sandy-mud substrate of the tidal zones in the Tagus and Sado estuaries. In the last quarter of the 3rd millennium BC, the dominance of the Ruditapes decussatus remained, but the biometric analyses have not revealed any evidence of over-exploitation. The diversity of species is greater than previously; a special remark is due to the presence of oyster. |
