Cephalopoda - Ammonitida - Cardioceratidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|J. K. Wright 2012||The genus is markedly dimorphic, with strongly ribbed microconchs (referred by Arkell (1941a, 1943) to Sagitticeras and Korythoceras) and macroconchs (referred by Arkell to Goliathiceras sensu stricto and Goliathites) characterized by moderately involute to strongly involute coiling and a depressed whorl section, with the whorl thickness greater than the whorl height. The ribbing is strong up to 100 mm, with a slight but distinct forward flexure over the venter. Arkell (1943, p.lxxxi) separated Goliathites, of which G. goliathus is typical, as a subgenus of Goliathiceras due to its suture having short, stocky lobes. Sutures are notoriously variable within ammonite species (Glowniak 2002, pp. 336, 343); Wright 2010, p. 36), and is not regarded here as a valid distinction.|
