Discussion / Comments: | ||||||
Tjalsma (1977): A broad species concept has been applied due to the wide variation. In the Miocene, specimens are frequently overcrusted with secondary calcite thus obtaining a very coarse surface texture. In typical specimens calcite growth on the apertural face has lowered the originally arched aperture to almost a slit (see Plate 7, Figures 10, 14). A similar phenomenon is seen in G. cf. bulloides described by Keany and Kennett (1972) from the upper Pliocene of a northern Antarctic core near Australia. Van Eijden & Smit (1991): Remarks. As true G. bulloides is very rare in the upper Oligocene at Site 758, we counted the few specimens as G. praebulloides Blow, 1959. Rögl (1985): To show the original species concept of G. bulloides the model no. 76 of d'Orbigny is figured here along with Banner& Blow's lectotype, which displays a somewhat stouter test but falls within the variability of the species. G. bulloides developed in the Middle Miocene, where it overlaps with its ancestor G. praebulloides. In that species chambers increase more rapidly in size, which results in a more elongate test shape with a higher and more asymmetrical arched aperture. Srinivasan (1975): Variation exists in the height and width of the aperture and in the size of the final chamber. Chaisson & Leckie (1993): Remarks: Widely accepted as an indicator of high productivity associated with upwelling waters (e.g., Duplessy et al., 1981), this species occurs from the middle Miocene to the Pleistocene; it is much more common, however, in the Pleistocene of Hole 806B. Its morphology is highly variable, but it is identifiable by its highly arched, umbilical aperture. The Miocene forms, in particular, are much smaller than temperate-water forms. Similar species: No thickened rim occurs around the aperture, and the test is finely perforate and hispid rather than cancellate, which distinguishes this species from Globigerina woodi and G. apertura. G. bulloides is less oblate than G. praebulloides. |
