Species Globorotalia (Hirsutella) hirsuta d'Orbigny 1839


Alternative name:
Diagnosis / Definition:
Kennett & Srinivasan (1983):
Test large, high trochospiral, highly convex on spiral side, concave on umbilical side, equatorial periphery ovate weakly lobulate, axial periphery biconvex, strongly tumid on spiral side; four chambers in the final whorl, increasing rapidly in size; sutures on spiral side strongly curved, depressed, on umbilical side sinuously radial, depressed; surface covered with pustular projections, concealed on early chambers by secondary thickening, finely perforate; umbilicus narrow, deep; aperture a low slit with an indistinct lip, interiomarginal, extraumbilical-umbilical.
Discussion / Comments:
Kennett & Srinivasan (1983):
Gr. (H.) hirsuta is distinguished by its thick, relatively high-spired test, four chambers in the final whorl, and pustulose surface.
