Entries in the Catalog of original descriptions: Whiteinella;

Short diagnosis: Test in low trochospiral coil, chambers globular, five to seven in the final whorl, increasing gradually in size, sutures radial, depressed; wall calcareous, finely perforate, surface pustulose, especially on earlier chambers; aperture an interiomarginal, umbilical-extraumbilical arch, bordered by a wide apertural flap or porticus that extends into the umbilicus, those of successive chambers overlapping but not attached to previous flaps.

Geological Range:
Last occurrence (top): within Campanian Stage (72.05-83.64Ma, top in Campanian stage). Data source: Total of range of species in this database
First occurrence (base): within Cenomanian Stage (93.90-100.50Ma, base in Cenomanian 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.
