Rank: Genus
Basionym: Globigerina oxfordiana
Type species: Globigerina oxfordiana Grigelis, 1958

Original description: Diagnose. - Sous-genre de Globigerina se differenciant du genre et de ses autres sous-genres par son ouverture virguline, non parfaitement ombilicale et pourvue d'une petite levre.

Famille Globigerinidae. Jurassique superieur- Cretace inferieur(?).

Entries in the Catalog of original descriptions: Globuligerina

Distinguishing features: Wall smooth or pustulose but without reticulate pattern


Morphology: Test trochospiral, low to medium to high spired (H/D ratio varies between 0.5 and 1.5). Mostly 4 and rarely 3–4 or only 3 chambers in the last whorl. Chamber shape globular or somewhat flattened, or may be oblong, elongated in a radial sense. Chambers rarely show an equatorial imperforate band. Apertural shape variable; often a medium to high arch; the arch may be an asymmetrical arch or comma shaped; aperture rarely a slit; aperture position mostly umbilical, but may be slightly extraumbilical. The aperture has a thickened and imperforate rim (lip) that may circle the aperture (as observed in well-preserved G. oxfordiana). Wall microperforate, smooth to pustulose; pustules may be pointed (pseudomuricae), or blunt; pustules may have pore mounds; pustules may fuse to form ridges.
