Isabelidinium korojonense
From Fensome et al., 2019:
Isabelidinium korojonense (Cookson and Eisenack, 1958, p.27–28, pl.4, figs.10–11) Lentin and Williams, 1977a, p.167.
Holotype: Cookson and Eisenack, 1958, pl.4, fig.10; Eisenack and Klement, 1964, p.191; Fensome et al., 1996, fig.1— p.2187. Originally Deflandrea, subsequently Isabelia (combination illegitimate), thirdly (and now) Isabelidinium. Age: Campanian–early Maastrichtian.
---------------------------------------------------------------------------------------------------
Locus typicus: Carnavron Basin, Australia
Stratum typicum: Campanian-Early Maastrichtian
Original description: Cookson and Eisenack, 1958, p.28: Deflandrea korojonensis
Theca rather variable in outline, typically somewhat quadrangular, with convex sides which become concave beneath the broadly rounded or bracket-shaped apex and narrow gradually towards a more or less truncate antapex, sometimes one side is prolonged as an abbreviated horn; a transverse furrow is not indicated. The capsule fills the theca laterally and is usually broader than long; a slightly polygonal pylome is present near its anterior end. The membrane of the theca is smooth, that of the capsule faintly granular.
Dimensions: Type - theca 71 x 52 µm; capsule 38 x 50 µm. Range - theca 61-80 x 38-53 µm; capsule 32-42 x 36-50 µm.

Isabelidinium korojonense (Cookson and Eisenack, 1961a) Lentin and Williams, 1977a. Pericyst typically somewhat quadrangular, with convex sides which become concave beneath the broadly rounded or bracket-shaped apex and narrow gradually towards a more or less truncate antapex, sometimes with one abbreviated antapical horn. No cingulum indicated. Size: Overall; 61-80 µm, breadth is 38-53 µm, endocyst is 32-42 µm by 36-50 µm
