Extra details from original publication
Relationships: 1967 hat der Autor in der höheren Trias Hedbergella artige Vertreter der Trias-"Globigerinen" entdeckt (Schmidita FUCHS) und bereits damals auf ihre phylogenetische Bedeutung für die kretazische Gattung Hedbergella BRÖNNIMANN & BROWN hingewiesen. Nun ist mit Mariannenina n. gen. das entwicklungsgeschichtlich fehlende V erbindungsglied glücklich gefunden, nachdem der Verfasser schon 1971 auf Grund der hohen generischen Differenzierung des Genus Hedbergella im tieferen Mittel-Barrème auf ihr viel früher notwendig erachtetes Erscheinen aufmerksam gemacht hatte. Unsere neue Gattung unterscheidet sich von Schmidita durch das offensichtliche Fehlen von äußeren Kennzeichen, die auf noch vorhandene Reste eines Internbaues deuten könnten, von Hedbergella durch den teilweise noch rein umbilikalen Mundschlitz und die wenig geblähten Kammern auf der Spiralseite.
Range : In Polen im Ober-Callovien bis Unter-Oxfordien angetroffen.
