Jenkins (1985):
G. quinqueloba has a distinctive hispid final chamber and a low aperture. It occurs today from the arctic and antarctic faunal provinces to the subtropical provinces (Bé, 1977) and first appeared in the Late Oligocene of the Southern Hemisphere. This initial appearance has been recorded in New Zealand, DSDP Leg 29 Site 281 on the South Tasman Rise and Leg 40 Site 360 in the Southeastern Atlantic (Jenkins, 1966a, 1975 1978c).
Van Eijden & Smit (1991):
Remarks. Globorotaloides suteri Bolli, 1957a is connected to a species resembling G. quinqueloba in the upper Oligocene at Sites 757 and 758 (Zones P22/N4) by intermediate forms. This form generally has five chambers in the final whorl {Globorotaloides suteri has three to four)and a more lobate outline. It is also connected with Fohsella kugleri (Bolli, 1957a), as indicated by intermediate forms.
Chaisson & Leckie (1993):
and in small numbers at this tropical site.
Similar species: Outside of its optimal range, this species may be smaller
than usual and be more easily confused with Turborotalita humilis. Globigerina
quinqueloba has only five chambers in the final whorl and a circular
outline, whereas T. humilis often has six or more chambers and is distinctly
more oblate in its equatorial outline. Both species can become encrusted with
secondary calcite, making them difficult to tell apart on the basis of texture. In
the absence of secondary calcite, T. humilis has a smoother test with peripheral
pustules, whereas G. quinqueloba has a typical globigerine wall texture. |
