Two described specimens of the gastropod Bellerophon tenuifascia J. de C. Sowerby, 1824, from the Carboniferous (Asbian) of the Isle of Man, United Kingdom, preserve repaired injuries resulting from environmental breakage and failed, non-lethal, predatory attacks. Deep scars attributed to predatory attacks are assigned to the ichnofossil Caedichnus and were focused on the mid-dorsal area of the aperture. Abundant small-scale scallops and chipping of growth lamellae distributed around the apertural margin are mainly the result of environmental damage. A deeply incised injury in the aperture of one specimen was probably a fatal injury.
