Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. W. Wright et al. 1996 | Extreme development of C. (Calycoceras), with inner whorls generally similar but distinguished by broader, flatter venter with strong ventral constrictions; main ribs with prominent umbilical and inner ventrolateral tubercles, at which ribs branch and cross venter transversely; untuberculate secondaries are intercalated on body chamber. Distinguished from Euomphaloceras by more rapidly increasing whorl breadth and absence of outer ventrolateral tubercles |
