Original Description

Test trochospiral. biconvex to slightly spiroconvex, umbilicate; periphery rounded, but not truncate; with or without imperforate peripheral band or weakly developed double keel. Chambers spherical to ovate, inflated. Suture depressed on both spiral and umbilical sides. straight to curved. Wall perfectly smooth to somewhat rugose; rugosities not aligned in meridionial pattern. Primary aperture umbilical, interiomarginal, covered by tegilla with intralaminal and infralaminal accessory apertures in perfectly preserved specimens. Outer wall radial hyaline perforate except for keels which are both radial hyaline imperforate and partly ultragranular hyaline, imperforate and the rugosities which are ultragranular hyaline, imperforate. Septal walls and tegilla microgranular hyaline. finely perforate.

Extra details from original publication
Remarks.- Archaeoglobigerina Pessagno, n. genus differs from Rugoglobigerina Bronnimann by lacking rugosites or costellae arranged in a distinctive meridional pattern (see remarks on Rugotruncana).
Archaeoglobigerina differs from Globotruncana s.s. (Cushman) (1) by lacking a truncate or angled periphery; (2) by having spherical to ovoidal chambers; (3) by lacking strongly developed keels; and (1) by having sutures which are predominantly depressed rather than raised and often beaded. Keels when present with both Archaeoglobigerina and Rugoglobigerina are weakly developed and do not give the periphery a marked truncate or angled aspect.
Most specimens of the type pecies A. blowi Pessagno, n. sp. lack keels aIthough they frequently show imperforate peripheral bands.

Range - M. renzi assembalge zone (upper Part) to Globotruncana fornicata-stuartiformis assemblage zone, Rugotruncana subcircumnodifer subzone insofar as known.
