Isabelidinium spinosissimum
Isabelidinium spinosissimum (Cookson and Eisenack, 1970) Lentin and Williams, 1977
Now Eucladinium. Originally Deflandrea, subsequently Isabelidinium, thirdly (and now) Eucladinium. See also Isabelia (combination illegitimate).
Holotype: Cookson and Eisenack, 1970, pl.11, fig.5
Paratype: Cookson and Eisenack, 1970
Locus typicus: Gambanga No. 1 Bore, Eucla Basin, W Australia
Stratum typicum: Senonian
Original description: Cookson and Eisenack, 1970, p.141: Deflandrea spinosissima
Shell moderately large with slanting to convex sides in both epitheca and hypotheca; a short, blunt apical horn and a single short antapical horn on one side. A large internal body either partially or almost entirely fills the hypotheca and part of the cpitheca. The archeopyle is broadly triangular to almost circular in outline. The whole surface of the shell is densely and very finely spinulose.
Dimensions: Holotype: c. 100 Ám long, 72 Ám broad. Range: shell c. 60-115 Ám long, 44-87 Ám broad.
