This research involves the study of the bioerosion on mosaic fragments recovered from the Underwater Archaeological Park of Baiae (Naples, Italy) caused by the boring sipunculans (Protostomia) and represents the first report of damage by Aspidosiphon muelleri Diesing 1851 on submerged Cultural Heritage. The present study defines the role of this organism in the deterioration of archaeological artefacts. The characteristic traces produced by the action of these organisms on stone materials are described. A set of criteria was established to distinguish the traces of these organisms from those produced by Polychaetes and Clionaid sponges. © 2015 Elsevier Ltd. Source

Marine boring bivalves responsible for bioerosion processes of lapideous artefacts, recovered in the Gulf of Pozzuoli (ancient Puteoli) and in the Blue Grotto in Capri Island (Naples, Italy), were examined. Intense bioerosion was observed in marble statues, limestone pavements and calcareous artefacts. Mytilid Lithophaga lithophaga, venerid Petricola lithophaga and gastrochaenid Rocellaria dubia have been identified; further two mere nestling species, arcid Barbatia barbata and trapezid Coralliophaga lithophagella, have been found inside vacant boreholes. Bivalve bioerosion plays an essential role in the deterioration of archaeological remains. Depending on their chemical composition, they are susceptible to corrosion. The determination of the damage level is very important to characterize the gravity of the biodeterioration and to define future strategies of conservation. © 2014 Elsevier Ltd. Source
