Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Valent et al. 2011 | Small hyolith with orthoconic or slightly cyrtoconic, dorsally concave conch. Dorsum possesses a sharp, keel-like ridges. Ligula is fairly long and nearly semicircular in outline. Sides of dorsal slopes are more or less concave in both genera placed in this family. Lateral edges are mostly highly rounded, the border between dorsal and ventral side lies a little above these edges. Sculpture consists of longitudinal and/or transverse elements – growth-lines or fine rounded or flat ribs of asymmetrical cross-section.
Platyclaviculate operculum having distinctly developed cardinal processes. Cardinal processes short, broadly diverging, and suboval in cross-section. Their bases are almost parallel to each other. Cardinal shield is slightly transversally concave. Its lateral margins are more or less curved posteriorly (adapically in living position). Distinct rooflets are visible. Surface bears concentric growth-lines sometimes in combination with fine radial ribs, which can be more distinct on cardinal shield. |
