Belongs within: Globorotaliidae.

Globorotalia is a genus of planktonic forams known from the Palaeocene to the present (Loeblich & Tappan 1964b).

Characters (from Loeblich & Tappan 1964b): Test free, trochospiral, periphery carinate, chambers angular, rhomboid, or angular-conical; sutures may be thickened, depressed to elevated; wall calcareous, finely perforate, but with nonporous keel or peripheral band, surface smooth to cancellate or hispid; aperture interiomarginal, an extraumbilical-umbilical arch bordered by lip, varying from narrow rim to broad spatulate or triangular flap.
