Citation: Gublerina Kikoine 1948

Rank: Genus

Basionym: Gublerina cuvillieri

Type species: Gublerina cuvillieri Kikoine, 1948

Original description: Se différencie totalement de tous les autres genres d'Heterohelicidae par son espace intercalaire déprimé et non pourvu de loges.

Entries in the Catalog of original descriptions: Gublerina

Distinguishing features: Test flabelliform, the 2 rows of chambers diverge leaving nonseptate central space that later is partially occupied by chamber proliferation.

Morphology: 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
