SpeciesSpecies within this genus include:[2]
The holotype of C disputabile, the type species, named by Spath,1927, which came from the Middle Jurassic of Hungary, is based on Phylloceras disputabile Zittil. Neocalliphylloceras Bresairie 1936, Captianioceras Kuvacs 1939 and Euphylloceras Draughtchitz 1953 are equivalent genera.[3] DescriptionCalliphylloceras has a smooth, compressed involute shell with a rounded venter and periodic constrictions in the internal mold; surface covered with lirae as in Phylloceras. The first and 2nd lateral saddles are usually triphyllic, others diphyllic.[3]DistributionThis species has been found in the Cretaceous of Canada, France, Japan, United States and in the Jurassic of Argentina, Austria, Germany, Hungary, India, Iran, Italy, Japan, Madagascar, the Russian Federation, Spain, Turkey, United States[2] Bibliography
