Taxonomy

Citation: Praehedbergellidae Banner & Desai 1988

Rank: Family

Original description: 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.

Entries in the Catalog of original descriptions: Praehedbergellidae

Distinguishing features: 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:

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

Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
Triangles indicate an event for which a precise placement has been suggested
Neptune data: this is a higher taxon page so Neptune data is not plotted. For the customisable plot option go to a genus page Parent: pf_mesozoic
