Boudagher-Fadel et al. (1996): Remarks: The specimens which formed the primary types of this species were found by its authors to occur with the primary types of C. conica (q.v.), and it is likely that all the specimens were glauconitic moulds. Like C. conica, the chambers were drawn (op. cit., above) to be subglobular, with four abutting the umbilicus; the aperture is an intraumbilical arch, as broad as the narrow umbilicus itself. It is possible that the original authors' drawings show a bulla on the holotype (1961, pI. 2, fig. 10) and the remains of a bulla on the figured paratype (1961, pI. 2, fig. 13; reproduced here as our Figure 2.1; 1). However, the spire is very low (height/diameter ratio of 0.6, compared to the height/diameter ratio for C. conica of about 1.2), and only five chambers were drawn to comprise the first whorl of both the holotype and the figured paratype. As remarked above (C. conica) , the early whorls would be clearly visible in a galuconitic mold. It is possible (as suggested by Banner and Desai, 1988, p. 147) that C. terquemi is the megalospheric partner of its contemporary C. conica. If this is so, these taxa would comprise the stratigraphically youngest example of dimorphism in meroplanktonic Conoglobigerina. |
