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.

Distinguishing features:
Parent taxon (pf_mesozoic):
This taxon: 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): at top of Aptian Stage (100% up, 113Ma, in Aptian stage). Data source: Total of range of species in this database
First occurrence (base): at base of Valanginian Stage (0% up, 139.4Ma, in Berriasian stage). Data source: Total of range of species in this database

Plot of range and occurrence data:

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
