Abstract

Abstract: The present study describes the role of the bivalve Rocellaria dubia Pennant, 1777 in the bioerosion process of submerged limestone artificial panels. The research was carried out in the central Mediterranean sea, in the Underwater Archaeological Park of Baiae (Naples, Italy). During the three year experimental period, the panels were submerged at 5 m depth and sequentially removed after 12, 24 and 36 months. R . dubia boreholes strongly affected stone material. The rate of bioerosion increased over time. After 36 months settlement still occurred with hundreds of boreholes and the shells were up to 13 mm in length. The results obtained concerning the impact of R . dubia on the experimental panels help to evaluate the bioerosive role of this species on submerged calcareous archaeological structures. Highlights: The settlement and colonization dynamics of Rocellaria dubia were studied. For the first time the study was conducted on lapideous archaeological artefacts. Bioerosion produced by this bivalve is highly dangerous on calcareous mosaic floors. Dimensions and morphology of burrows were studied on archaeological and experimental substrates. R . dubia has a pioneer role in the colonization of submerged artefacts.
