Morphology
The typical Cadoceras shell is strongly ribbed, subglobular, with a broadly rounded venter, strongly embracing whorls, deep umbilicus, and a smile-like crescent-shaped aperture. Ribs arise from the umbilical shoulder and bifurcate (divide in two) about mid flank and cross the venter without interruption. Species vary in the nature of ribbing and roundness of the umbilical shoulder.{{Cite web |url=http://www.ammonites.fr/Familles/Cardioceratidae.htm |title=ammonites.fr Cadoceras entry |access-date=2015-03-18 |archive-date=2021-04-13 |archive-url=https://web.archive.org/web/20210413195545/http://ammonites.fr/Familles/Cardioceratidae.htm |url-status=dead }}[http://www.jsdammonites.fr/638.html jsdammonites.fr Cardioceratidae entry]
