Original description: Gublerina:

Entries in the Catalog of original descriptions: Gublerina;

Distinguishing features: Test compressed, flabelliform, early stage planispiral, later biserial and increasing rapidly in breadth, the two series of chambers diverging to leave a broad nonseptate central area that later is partially occupied by chamber proliferation, sutures depressed; wall calcareous, finely perforate, ornamented with longitudinal costae and nodes, most prominently in the early stage; aperture an arch at the base of the final chamber.

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 Campanian Stage (72.05-83.64Ma, base in Campanian 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

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: Heterohelicidae
