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.
