- Diagnosis
- Endocarp bisymmetric, dorsiventral length 7.0–7.6 mm, width 5.0–6.4 mm (n = 4), laterally flattened, obliquely obovate in lateral view with broad rounded dorsal surface, with a dorsal crest (“keel”) running around the plane of bisymmetry; base obliquely truncate. Central condylar depression obpyriform, smooth and more or less flat. Central area with distinctive oval to circular foramen central to the endocarp, and a slit extending from foramen to base. Central area surrounded by a slightly asymmetric horseshoe-shaped raised ornamented area (lateral crest). One limb of the endocarp distinctly longer and protruding at the base when fully preserved. Lateral crest surmounted by c. 30 conspicuous spines. A corresponding row of spines located along dorsal crest at periphery of the endocarp; these spines sometimes connected to spines on the lateral crest by shallow ridges.
