Species Conoglobigerina conica Iovceva & Trifonova 1961

Discussion / Comments:

Boudagher-Fadel et al. (1997):
Remarks: We were unable to borrow any primary type or topotype specimens of this species, which Masters (1977, p. 464) claims to have been based on glauconitic moulds. Dr Trifonova kindly sent us unpublished photographs of some primary types to supplement the drawings which were originally published (Iovceva and Trifonova, 1961), some of which are reproduced here (Figure 2.1; 4-6). The species appears to possess an arched, intraumbilical aperture, conoglobigerine in type, inflated and subglobular chambers, and a very high spire (d/t = 1.0-1.3 approx). Four chambers comprise the last whorl, but many more (seven!) were drawn by the authors to form the first whorl of the holotype (if that specimen was a glauconitic mould, these earliest chamber moulds may well have been clearly visible); if this is so, the taxon might have been the microspheric partner of its contemporary, C. terquemi (Iovceva and Trifonova) (q.v.) (as suggested by Banner and Desai, 1988, p. 147).
