Taxonomy
Original description: Conoglobigerinidae BouDagher-Fadel et al. 1997:
Entries in the Catalog of original descriptions: Conoglobigerinidae;
Distinguishing features: Small (<200µm), microperforate wall, 3-4 globose chambers in final wall, aperture umbilical
Geological Range:
Last occurrence (top): within Valanginian Stage (133.88-139.39Ma, top in Valanginian stage). Data source: Total of range of species in this database
First occurrence (base): within Bajocian Stage (168.28-170.30Ma, base in Bajocian 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
