Abstract

As a forerunner to eventual classification of the superfamily Terebratellacea Allan (1940), six new genera are proposed here. They are Eodallina (type sp., E. peruviana n.sp.), upper Triassic, Peru; Antigoniarcula (type sp., Ismenia perrieri), lower Jurassic, France and England; Oblongarcula (type sp. Terebratula oblonga), lower Cretaceous, Europe; Arenaciarcula (type sp., Terebratella fittoni), lower Cretaceous, western Europe; Trifidarcula (type sp., Terebratella trifida), lower Cretaceous, England; Dereta (type sp., Terebratula pectita), middle Cretaceous, Europe.
