Abstract

Naticid boreholes observed on the shells of molluscs collected from three different layers of Wind mBrickyard (Late - Oligocene / Egerian) have been examined. Traces of Naticid predation occured on the tests of bivalves, gastropods and scaphopods.Mode of life, feeding habit of molluscs, distribution of successful, unsuccessful and unfinished borings have been investigated and compared. Number of borings is low in the case of mollusc shells of the Molluscan Clay. Encreasing number of borings can be observed in the case of the molluscs of the “x”-layer and the “k”-layer. Occurrence of multiplied borings and cannibalism also have been found. Regarding the feeding habit suspensionfeeders and scavengers are dominant among the prey species.
