DÁVID, Á.: Naticid prédation on Late-Oligocene (Egerian) corbulid bivalves collected from three localities of NE - Hungary

Fig. 1: Geographical position of the three localities discussed in this paper. 1. Wind Brickyard, Eger; 2. Rozália cemetery, Eger; 3. Nyárjas Hill, Novaj Corbulid valves' conchiolin sheets have been considered to offer defence against prédation by boring gastropods (Harper, E.M. 1994). This study aims to examine the location and distribution of Naticid predatory borings on the shells of two Corbula species collected from Late Oligocène (Egerian) outcrops of NE Hungary. Description Naticid predatory boreholes on the valves of Corbula basteroti Homes All the specimen were collected from three layers of Wind Brickyard locality (Table 1). 15,2 percent of the valves is bored. In the case of the molluscan clay multiplied boring can
