AbstractMytilus antiquorum J. Sowerby, 1821, is recorded from the Coralline Crag Formation of East Anglia (UK) and the Lillo Formation (Oorderen, Kruisschans and Merksem members) of the Antwerp area (Belgium). The species is diagnosed on the basis of newly collected material and differentiated from modern European mussel species. The presence of M. antiquorum in the southern North Sea Basin is restricted to the Middle (Piacenzian) and early Late Pliocene (Gelasian). A possible occurrence of the species in the latest Pliocene of northern Greenland is discussed. A second Middle- Late Pliocene North Sea Basin species, tentatively referred to as M. edulis forma giganteus Wood, 1874, is diagnosed and discussed. The systematic status of this species remains unsolved. In the Late Pliocene, a third mussel species occurs in the area, tentatively identified as Mytilus trossulus Gould, 1850.
