Original description: caractérisée par sa forme trochospiralée mais nettement différente de G. dubia et rattachée à G. portsdownensis par la taille presque uniforme ds loges du dernier tour,

Translated from French: Characterized by its trochospiral form but clearly different from Globigerina dubia Egger. Related to Globigerina portsdownensis Williams and Mitchel because of the almost uniform size of the chambers in the last whorl.

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
