Taxonomy

Original description:

Low trochospiral, generally slightly lobate in outline, numerous chambers (7–11) in the last whorl, globular, sutures straight and depressed on both sides; wall finely perforate; wall surface rugose to smooth, with rugosities masking the inner whorl, then covering the first chambers of the last whorl, frequently organized in irregularly sized ridges that may cover the pores and run parallel to the spiral suture; surface of later-formed chambers may bear volcano-like perforation cones that progressively attenuate toward the ultimate chamber; shallow umbilical area moderate to large in size; umbilical area may be covered, at least partially, by large flaps from the ultimate and penultimate chambers that fuse along a slightly depressed line forming a cover-plate; primary aperture an interiomarginal arch, umbilical-extraumbilical extending toward the periphery; may have one to two small, weakly developed umbilical accessory (infralaminal) apertures in the last chambers.

Distinguishing features:
Parent taxon (Hedbergellidae): Test trochospirally coiled, primary aperture interiomarginal, extraumbilical-umbilical, with prominent apertural lip, apertures of earlier chambers remain visible around the umbilical region; no sutural secondary apertures.
This taxon: Test low trochospiral, numerous chambers (7–11) in the last whorl, sutures straight and depressed on both sides; wall finely perforate, rugose to smooth,rugosities organized in irregularly sized ridges that may cover the pores and run parallel to the spiral suture, may have bear volcano-like perforation cones; umbilical area may be covered by large flaps primary aperture umbilical-extraumbilical; may have one to two small umbilical accessory apertures in last chambers.

Geological Range:
Last occurrence (top): at top of P. rohri zone (100% up, 113.2Ma, in Albian stage). Data source: Total of ranges of the species in this database
First occurrence (base): within P. rohri zone (113.22-116.60Ma, base in Aptian stage). Data source: Total of ranges of species in this database

Plot of range and occurrence data:

• Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
• Triangles indicate an event for which a precise placement has been suggested
• Neptune data: This is a higher taxon page so Neptune data is not plotted. See also: customisable plot Parent: Hedbergellidae
