Species Marginotruncana pseudolinneiana Pessagno 1967


Discussion / Comments:
Caron (1985):
The species has the same general shape as Globotruncana linneiana, but differs in having an umbtlical-extraumbilical primary aperture. Its portici tend to develop into tegilla with infra-and intra-laminal accessory apertures. From M.coronata it differs in its-two more strongly developed keels, divided by a wider peripheral band and in its typical rectangular axial profile.
