Korojonia dubiosa Cookson and Eisenack, 1958
Holotype: Cookson and Eisenack, 1958, pl.12, fig.13
Locus typicus: Carnavron Basin, W Australia
Stratum typicum: Cenomanian-Early Maastrichtian
Original description: Cookson and Eisenack, 1958, p. 54
Outer membrane broadly fusiform with blunt apices one of which sometimes carries a minute projection. The internal capsule is oval and thicker walled than the outer membrane from which it is seperated by a rather wide space. Sometimes faint indications of a equatorial girdle can be seen at each side of the shell. In most of the species, as in the type, the outer meembrane is partially folded over the shell.
Dimensions: Type - 86 x 48 Ám overall; cyst 48 x c. 33 Ám. Range - 66-95 x 38-48 Ám overall.
