Species Globorotaloides suteri Bolli 1957


Diagnosis / Definition:
Kennett & Srinivasan (1983):
Test low trochospiral, equatorial periphery lobulate, axial periphery rounded; chambers spherical to ovate, four to five rapidly increasing chambers in the final whorl, the final chamber often smaller than the penultimate; spiral sutures slightly curved to radial, depressed, on umbilical side radial, depressed; surface coarsely punctate, the punctae often coalescing to produce a cancellate pattern ; aperture a low arch, interiomarginal, umbilical-extraumbilical in early stage, later becoming interiomarginal, umbilical, often covered by bulla-like final chamber.
Bolli (1957):
Shape of test low trochospiral, biconvex; equatorial periphery lobate, in small specimens slightly elongate; axial periphery rounded. Wall calcareous, perforate, surface finely cancellate. Chambers ovate to spherical; about 11-14, arranged in 2-2 1/2 whorls; the 4-5 chambers of the last whorl increase fairly rapidly in size. Sutures on spiral side slightly curved to radial, depressed; on umbilical side radial, depressed. Umbilicus fairly wide, open in immature specimens, in mature specimens partly or completely covered by bulla like chamber. Aperture a slit or low arch; interiomarginal, umbilical extraumbilical in early stage, later becoming interiomarginal, umbilical, which in mature specimens becomes covered by a bulla like chamber with usually one, rarely two or more infralaminal apertures. Coiling random or some predominance for dextral. Largest diameter of holotype 0.35 mm.
Tjalsma (1977):
Specimens differ from Globorotaloides suteri mainly for their coarse cancellated wall surface. Adult specimen typically have 3'/2 chambers in the final whorl and 5, occasionally 6 in the previous one. The low umbilical aperture is bordered by a lip. The aperture of preadult specimens tend to be extraumbilical in position.
Discussion / Comments:
Kennett & Srinivasan (1983):
Gd. suteri differs from Gd. variabilis in having more inflated early chambers and less curved sutures.
Bolli & Saunders (1985):
Compared with G. variabilis, G. suteri is in general smaller with early chambers more inflated and intercameral sutures on the spiral side more radial. As in G. variabilis the final bulla like chamber is quite variable in size and shape; it may be low and deflated or quite distinctly inflated as in the holotype of the two species. Quite frequently this last bulla like chamber may be absent.
Bolli (1957):
Globorotaloides suteri, new species, is distinguished from G. variabilis, new species, by the more inflated early chambers, less curved sutures and fewer chambers.
Tjalsma (1977):
A bulla as is common in G. suteri is present only in a minor part of the population. G. cf. suteri may be a high latitude variant of G. suteri, similarly to G. testarugosa(J enkins) from New Zealand from which it differs mainly by the Globigerina character of the adult. At Site 329 it is common in Cores 31-28 (Oligocene) and the core catcher of Core 27 (early Miocene).
Van Eijden & Smit (1991):
Remarks. Usually dominant (commonly about 60%) in the 125-250-ìm fractions, G. suteri is also common in the <125-ìm fractions. In the upper Oligocene samples the species is connected a four- to five-chambered form with a more lobulate outline by intermediate forms. (See Globigerina quinqueloba Natland, 1938.)
Chaisson & Leckie (1993):
Similar species: Globorotaloides suteri has more inflated chambers than G. variabilis, and it lacks the subacute peripheral margin of the latter taxon. G. hexagona is thinner and has more lobate chambers than G. suteri.
