A large adult shell of the prosobranch mesogasropod 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 mea, at least four presumed bivalve borings assigned to the ichnotaxon Gastrochaenolites Leyrnerie. In addition to these informative, but partly temporally equivocal, biotic interactions, this represents the first fonnal recording of the latter ichnotaxon in the Jamaican rock record. Uniquely, the Gastrochaenolites borings perforate both the gasfopod shell and into the sediment infill. Other, less prominent borings in the Str. gigas shell includg Entobia Bronn and Caulostrepsis Clarke.
