Taxonomy

Citation: Kuglerina Brönnimann and Brown 1956
Rank: Genus
Basionym: Rugoglobigerina rngosa subsp. rotundata
Type species: Rugoglobigerina rngosa subsp. rotundata Brönnimann, 1952
Taxonomic discussion: Helvetiella was described as differing from Rugoglobigerina in lacking a meridional alignment of rugosities and from Archaeoglobigerina in lacking an imperforate carinal band (although none is present in the type species of either) and in the heavily ornamented surface. However, it appears very similar to Kuglerina and is here regarded as synonymous.

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:

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.
