Abstract

Distribution and position of traces of bioerosion in oyster valves is compared in the case of two Early-Miocene (Carpathian) age localities. Activity of Clionid sponges, Polychaete worms, boring bivalves and Cirripeds have been observed. On the basis of higher diversity of ichnotaxa, higher proportion of Polychaete borings and lower rate of sponge activity we can conclude on shallower marine circumstances at the Nagyvisnyó locality.
