Taxonomy
Original description: Mit der Gattung Cuneolina, wie sie ursprünglich von d'Orbigny aufgestellt wurde, lässt sich unsere Form ohne Zwang nicht vereinigen. Sie weicht aber auch von den typischen Textularien so weit ab, dass die Aufstellung einer neuen Gattung — Pseudotextularia — gerechtfertigt sein dürfte. Es ist nicht unmöglich, dass die von verschiedenen Autoren beschriebenen tri- und multiserialen Textularien ebenfalls hieher gehören.
Entries in the Catalog of original descriptions: Pseudotextularia
Distinguishing features:
Parent taxon (Heterohelicidae): Aperture symmetrical, ranging from a low slit to a high arch at the base of the final chamber, becoming terminal in uniserial taxa.
This taxon: Adult biserial chambers expanded such that test breadth is greater than width in side view.
Morphology:
Geological Range:
Last occurrence (top): at top of P. hariaensis zone (100% up, 66.4Ma, in Maastrichtian stage). Data source: Total of ranges of the species in this database
