Abstract |
The present paper contains a systematic revision of the genera Entolium and Propeamussium (Amusiidae) and Syncyclonema (Pectinidae, Bivalvia, Mollusca) in European Cretaceous boreal seas.In Entolium two species are described, in Propeamussium one, and in Syncyclonema eight of which one (S. hagenowi) is new to science, two (S. gamsensis and S. haggi) are renamed and a former variety is given specific status (S. haldonensis).Stress is laid on redefining the species, mostly along biological lines. Material has been studied from as many localities as possible; a nomenclatorial critical revision is undertaken; type-specimens have been located; type-strata and type-localities are indicated. |
