Citation: Pseudotextularia Rzehak 1891
Rank: Genus
Basionym: Cuneolina elegans
Type species: Cuneolina elegans Rzehak, 1891
Taxonomic discussion: A neotype (Natural History Museum, Vienna, Geol.-Palaeont. Coln. MI-465) was designated (S. Nash, 1981, *2231, p. 74) for Pseudotextularia elegans (Rzehak) from the type locality.

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: Adult biserial chambers expanded such that test breadth is greater than width in side view.

Test morphology: Test subtriangular in outline, with biserially arranged, inflated chambers compressed parallel to the line of junction between the two series of chambers so that the test appears broader in apertural or edge view than from the sides with the zigzag suture between chambers, sutures depressed; wall calcareous, finely perforate, surface with longitudinal, slightly irregular to discontinuous fine to medium coarse costae; aperture a broad low to medium arched basal opening bordered by a narrow lip.

Geological Range:
Last occurrence (top): within Maastrichtian Stage (66.04-72.05Ma, top in Maastrichtian stage). Data source: Total of range of species in this database

Plot of occurrence data:

Dec 2017 - Plotting of Neptune data has been re-enabled on the Mesozoic pages following revision of the age-models in Neptune. The data is, however, still very sparse for the Early Cretaceous
