Original description: Pseudotextularia:

Entries in the Catalog of original descriptions: Pseudotextularia;

Short diagnosis: 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
First occurrence (base): within Turonian Stage (89.77-93.90Ma, base in Turonian stage). Data source: Total of range of species in this database

Plot of occurrence data:

NB Plotting of Neptune data has been disabled on the Mesozoic pages because the dataset is both small and badly affected by a few sites with erroneous age models (our obs Huber, Petrizzo, Young, Nov 2016). The data can still be viewed via the range plottertool - tools menu.
