Original description: Praehedbergellidae Banner & Desai 1988: Diagnosis. Globigerinacea with trochospiral tests, in which the primary aperture is intraumbilical or intraumbilical-extraumbilical and which possess a microperforate wall lacking muricae, crystallite pustules or spine bases; differs from the Favusellacea in its lack of muricae (and in possessing a calcitic test) and from the Schackoinidae in not becoming planospiral.

Short diagnosis: Globigerinacea with trochspiral tests, in which the primary aperture is intraumblical or intraumbilical-extraumbilical and which possess a microperforate wall lacking muricae, crystallite pustules, or spine bases; differs from the Favusellacea in its lack of muricae (and in possessing a calcitic test) and from the Schackoinidae in not becoming planispiral.

Geological Range:
Last occurrence (top): within Aptian Stage (112.95-126.30Ma, top in Aptian stage). Data source: Total of range of species in this database
First occurrence (base): within Hauterivian Stage (130.77-133.88Ma, base in Hauterivian 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.
