A large adult shell of the prosobranch mesogastropod Strombus gigas Linne from the late Pleistocene Port Morant Formation, southeast coastal Jamaica, exhibits the coral Siderastrea radians (Pallas) attached to two areas of the upper surface and, in its dorsal area, at least four presumed bivalve borings assigned to the ichnotaxon GastrochaenolitesLeymerie. In addition to these informative, but partly temporally equivocal, biotic interactions, this represents the first formal recording of the latter ichnotaxon in the Jamaican rock record. Uniquely, the Gastrochaenolites borings perforate both the gastropod shell and into the sediment infill. Other, less prominent borings in the Str. gigas shell include Entobia Bronn and Caulostrepsis Clarke.....
