Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. Hoffmann 2015 | hell size ranges from small to huge; whorl section rounded-circular to depressed or compressed, or subquadrate; whorl expansion rate varies from low to high; whorls very evolute, only touching or slightly overlapping, ornamented with prominent growth lines or riblets, usually fimbriate, and strigate ornament in some; ribs straight to sinuous, occasional weak to storng , regular to irregularly spaced, constrictions on internal mold, associated with lamellar flares on shell, and these may be more numerous on inner whorls. Suture line as for family, septal lobe in Cretaceous forms stronger than in Jurassic forms (Kennedy & Klinger, 1978; Hoffmann, 2010). |
