Diconodinium inflatum
Diconodinium inflatum Eisenack and Cookson, 1960
Now Laciniadinium?. Originally Diconodinium subsequently (and now) Laciniadinium?.
Holotype: Eisenack and Cookson, 1960, pl.1, fig.13; Morgan, 1977, pl.2, figs.5a-c
Locus typicus: North of Gingin, W Australia
Stratum typicum: Late Albian-Cenomanian
Original description: Eisenack and Cookson, 1960, p. 4
Shape broadly oval in outline, epitheca longer than hypotheca and terminated by a rather short, hollow, bifid process, hypotheca with a short spine. Shell-membrane two-layered, outer layer ornamented with rather widely-spaced spinules which tent to be arranged in longitudinal rows and to project slightly beyond the surface in optical section; region of "longitudinal furrow" smooth, lines bounding it clearly defined.
Dimensions: Type 88 Ám long, 67 Ám broad. Range 80-95 Ám long, 52-67 Ám broad.
