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

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

Hi Jeremy,

Could you please tell me in which superfamily do you include Conoglobigerinidae?

Thank you,

At least for now we are not using superfamilies in the Mesozoic module so I don't know.
