Eurydinium ingramii
From Fensome et al., 2019:
Eurydinium ingramii (Cookson and Eisenack, 1970a, p.143, pl.12, figs.7–9) Stover and Evitt, 1978, p.105. Holotype: Cookson and Eisenack, 1970a, pl.12, fig.9; Eisenack and Kjellström, 1975a, figure to left — p.190a; Fensome et al., 1996, fig.3 — p.2167. Originally Deflandrea, subsequently Alterbia (combination illegitimate), thirdly Senegalinium, fourthly (and now) Eurydinium. Age: Albian–Cenomanian.

Locus typicus: Madura No. 1 Bore, Eucla Basin, W Australia
Original description: Cookson and Eisenack, 1970, p.143: Deflandrea ingramii
Shell rather flat, approximately oval in outline with a thin, untabulated wall, and a small, flat, median apical projection on the left-hand side. Slight lateral concavities indicative of a transverse girdle are evident in the holotype.
A large oval capsule almost fills the shell both laterally and longitudinally. Its wall is slightly thicker than that of the shell and appears to be ornamented with small, closely arranged, low, dot-like thickenings (Pl. 12, fig. 8).
A six-sided archeopyle is outlined in the apical region of the epitheca of the holotype and the example shown in Pl. 12, fig. 8.
Dimensions: Holotype: length c. 67 µm, breadth 48 µm. Paratype: c. 75x56 µm. Range: length c. 68-80 µm, breadth 46-66 µm.
