Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. S. Peel 2020 | Intermediate plate oval, with sub-parallel sides in dorsal perspective (Fig. 5B), saddle-shaped in lateral view with convex antero-lateral margins (Fig. 5C). Postero-lateral marginal areas shallowly concave in dorsal view, forming wing-like structures adjacent to the convex middorsal area. Apical area about as long as broad, with broad transverse ribs fading laterally; lacuna very shallow. Shell growth mixoperipheral with dorsal ornamentation of comarginal ridges. Outer shell layer formed by imbricating lamellae which slope towards the antero-lateral margins, with each lamella overlying the previous lamella. Inner shell layer with radial fibrous structure.
Head plate oval, width about two thirds of length, with a short, convex supra-apical surface and a long, concave sub-apical surface. Early growth stage bulbous, located nearer to the slightly pointed, supra-apical margin. Concave sub-apical train with sub-quadrangular and slightly arched margin. Holoperipheral growth, with ornamentation of comarginal cords that is traversed by broad radial folds on the sub-apical surface near the margin. |
