Original Description Test free, trochospiral, umbilicate, chambers rounded to sphaerical, sutural, radial to slightly curved, on both sides depressed throughout ; wall calcareous, fine and irregularly perforate, often also pustules perforate. Surface of test rought, with abundant, irregularly dispersed pustules. In the parts of test with dense pustules the surface of test is typically rugose. The pustules are of irregular dimensions and are often missing on the last chamber.
Aperture interiomarginal - umbilical, mostly narrow slot-like, at the base of the last chamber, not protected by lip. Size: Etymology: The composed name is derived from the latin word post = after; and from the generic name of the Rugoglobigerina. Extra details from original publication Stratigraphicrange: Uppermost Maastrichtian (where are no more globotruncanas) and Lowermost Danian.
Phylogenetic relations: This genus developed from Rugoglobigerina BROENNIMANN under ecologically unfavourable conditions at the Cretaceous—Paleogene boundary. From Postrugoglobigerina nov. gen. we derive
