Original description: Gitterschale einfach, ungegliedert, ausgeschweift kegelförmig, fast zeltförmig, oben in eine stumpfe Spitze ausgezogen, von welcher concav gebogene Radialbalken in dem Kegelmantel herablaufen, unten mit einer sehr weiten kreisförmigen Mündung geöffnet. Centralkapsel kegelförmig-birnförmig, in der Spitze eingeschlossen, ungelappt (?).

Geological Range:
Last occurrence (top): Extant Data source: Total of range of species in this database
First occurrence (base): at base of Gelasian Stage (0% up, 2.6Ma, in Gelasian stage). Data source: Total of range of species in this database

Plot of 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
Neptune data: This is a higher taxon page so Neptune data is not plotted. See also: customisable plot Parent: Acropyramiidae
