Calliphylloceras is an ammonite belonging to the Phylloceratidae that 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]
The holotype of C disputable, the type species, named by Spath,1927, which came from the Middle Jurassic of Hungary, is based on Phylloceras disputable Zittil. Neocalliphylloceras Bresairie 1936, Captianioceras Kuvacs 1939 and Euphylloceras Draughtchitz 1953 are equavalent genera.[3]
