From Fensome et al., 2019:
Apteodinium tuberculatum Cookson and Eisenack, 1970a, p.146–147, pl.12, fig.14. Holotype: Cookson and Eisenack, 1970a, pl.12, fig.14; Jan du Chêne et al., 1986a, pl.14, figs.9–11. Age: Senonian.
---------------------------------------------------------------------------------------------------
Original description: [Cookson and Eisenack, 1970, p. 146]:
Description:
Shell untabulated, relatively large, broadly oval in outline with a short, solid, median apical horn which narrows from a relatively broad base to a small apex ornamented by a small terminal and two minute lateral spiny projections. A relatively wide, median, spiral girdle is clearly outlined, and a large archeopyle occupies a considerable portion of the epitheca. The surface of the shell is ornamented with low, closely arranged, somewhat spinous thickenings.
Dimensions:
Holotype: c. 128 µm long, 105 µm broad.
