    Comments

    This was found in the spoils from dredging the C&D Canal in the 1980s. Recent removal of spoils sand for road construction in the area exposed previously- inaccessible layers of sand. This species is not listed in the Delaware Geological Survey's bulletin about the fossils of the Canal. It is distinguished by its small size and non-plicate (no ridges) central area of the shell.
