Species Conoglobigerina avarica Morozova 1961

Discussion / Comments:

Boudagher-Fadel et al. (1997):
Remarks: C. aravica is a very high spired species, and the spire of the holotype itself is fifty per cent higher than the tes is broad (our new photograph of the holotype (Plate 2.4, Fig. 1) shows it well). The same ratio is seen in our figured paratype (Plate 2.4, Fig. 1). There are three subglobular chambers in the final whorl; the aperture is an arch within the small umbilicus. There are about five chambers in the earliest whorls, judging from the paratypes figured here (Plate 2.4, Fig. 6) and by Morozova (1961, pl. 2, fig. 12). The paratypes figured by Morozova (1961) with four chambers in the last whorl (including that figured here, Plate 2.4, Fig. 5) are referred by us to C. dagestanica. The wall of the test may seem smooth under the lower magnification, but SEM shows it to be covered by pseudomuricae (Plate 2.4, Fig. 4)
