Treatment

Genus Nomismocanites gen. nov.

urn:lsid:zoobank.org:act:B644E02C-31E3-4979-B300-4AC631D7D8FD

Etymology

Combination of the genus names Nomismoceras and Eocanites because of its coin-shaped conch morphology.

Type species

Nomismocanites raritas gen. et sp. nov.

Diagnosis

Genus of the Subfamily Prolecanitinae with coin-shaped conch with high whorl overlap zone. Ornament with strongly concavo-convex, rectiradiate growth lines.

Remarks

Nomismocanites gen. nov. differs from all other Early Tournaisian prolecanitid ammonoids in the extremely discoidal conch and the relative high whorl overlap rate (IZR about 0.30 in Nomismocanites but 0.05 to 0.15 in species of Eocanites , for instance). Only Kahlacanites Ebbighausen, Bockwinkel, Korn & Weyer 2004 has a similar overlap rate but this genus differs in the much wider whorl profile.
