Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Kříž 2008 | Medium sized (L = 44.0), elongated (L/H = 3.28), equivalve, and inflated shells (H/W = 1.22–1.44). Umbones are prominent, extended above the dorsal margin, gibbous, and incurved, less than 1/5 of the shell length from anterior. Umbonal ridge is indistinct, rounded, and became obsolete before reaching posterior extremity. Posterior part of concave dorsal margin is curved upward. Posterior extremity of dorsal margin is obliquely truncated. Anterior part is short and rounded. Ventral margin is slightly concave, with weak ventral sinus, subparallel with the most of the dorsal margin. Lunule and long escutcheon are well developed. Outer surface sculpture consists of irregular growth wrinkles; ventrally of umbonal ridge distinct, convex, regularly spaced growth bands and furrows are developed. Surface sculpture of the anterior part of the shell is composed of narrow irregularly spaced growth bands and furrows. Posteriorly, in the wide radial sinus the number of growth bands decreases and they became wider and regularly spaced. Ligament opisthodetic, internal features and hinge unknown. Shell wall is thin (0.14–0.31 mm). |
