Belongs within: Globigerinidae.
Globigerina is a genus of planktonic forams known from the Palaeocene to the present. The test is trochospiral with globular chambers and an umbilical aperture (Loeblich & Tappan 1964b).
Characters (from Loeblich & Tappan 1964b): Test free, trochospiral, chambers spherical to ovate; wall calcareous, perforate, radial in structure, surface may be smooth, pitted, cancellated, hispid or spinose; aperture interiomarginal, umbilical, with tendency in some species to extend to slightly extraumbilical position, previous apertures remaining open into umbilicus.
