Description:
Invariably preserved as internal pyrite moulds. Large, subglobular test, slightly compressed, ovate in transverse section. Rounded periphery, sutures depressed, chambers inflated. Chambers increase gradually in size as added, sutures slightly curved. Aperture a comma shaped opening on the ventral face of the last formed chamber.Occurrence:
Confined to V. herricki and L waliacei Zones in Venezuela. Offshore Cabinda found in CABGOC 128-3 between 9,980’ and 10,160’, and in CABGOC 115-1X between 3,290’ and 8,580’, acme at 6,420’.Remarks:
Brady (1884) remarked that ’C. subgiobosa occurs in all the great ocean basins, and is for the most part a deep water species'. Originally described from Recent sediments of an un designated location, Renz (1948) found the species throughout the Agua Salada Basin, but most common in the Acostian. Blow (1959) said of the species it is ’ubiquitous although rather scarce’. Also known from Colombia, Ecuador, Trinidad, Cuba, Jamaica, Mexico, and California. See Bornmalm (1997) (p. 64 - 65) for an ecological review. Recognised in the Miocene of the Gulf of Suez region (Souya 1965). Found to be slightly truncate and flattened towards the apertural end in the Miocene of Egypt (Macfadyen 1930). Specimens compare well with those of the Heron- Alien and Earland collection (P32399-32450, P32472-32499), though some dwarfism of these specimens is evident.Globocassidulina subgiobosa honzontalls(Cushman & Renz)

Description; Elongate slender test. Tapers gently to the apertural end, much of the adult growth with parallel sides. Microspheric and megalospheric forms recovered differing only in the extent of the initial triserial chambers. Megalospheric shows a short rounded triserial stage, microspheric form has a acute extended triserial portion. Subsequent biserial and uniserial growth in both forms. Test wall thin and covered with numerous short, low, longitudinal striae, perforate. Aperture a terminal round opening on a short neck.

Rathbum and Corliss (1994) considered the genus to be indicative of high organic carbon sediments in low oxygen conditions, while Bolli et. al. (1994) considered it to be facies tolerant. Whittaker (1988) commented on the close relationship of B.alazanensis Cushman, 6. dominicana Bermudez, B. jugosa Cushman & Parker, and B.
