The borings are circular or elliptical, straight-sided and have a diameter of 40–90 μn. Autozooids were drilled in preference to heterozooids and most borings penetrate the operculum. The shape and distribution of boreholes suggests that they were made by a predator attacking one zooid at a time. The predator responsible may have been a gastropod, most probably a nudibranch or a micromorphic muricid. Bryozoa, Gastropoda, predation, borings, Upper Cretaceous.Read More
