AB Along the Biscay (Armintza-Sopelana) abrasion carbonated platform, at least four different marinebioeroders have been identified (sponges, polychaete annelids, endolithic bivalves and sipunculids). Themost abundant recent structures (Gastrochaenolites), correspond to endolithic bivalves as Pholas genera,which in many occasions have preserved their valves in a hard carbonated substrate. There exists a lithologiccontrol (carbonated vs siliciclastic rocks) in the hard substrate. Below the 60% CaCO3 it is not possiblebioeroder colonization, which can reach high values (70 units/100cm2) in appropriate conditions. Thearagonite composition and the complex cross foliated and regular simple prismatic microstructures of thePholas valves are characteristic. The dominant drilling mechanism is chemical from dissolution of carbonatedhard substrate
