Crioceratites is an ammonite genus from the Early Cretaceous belonging to the Ancylocerataceae.
Crioceratites was formerly included in the Ancyloceratidae, in the subfamily Crioceratinae which was subsequently elevated in rank to the family Crioceratidae. Crioceras and Toxoceras d'Orbigny and possibly Emericiceras Sarka 1954 are junior synonyms.
Species within the genus Crioceratites include:
Crioceritites is coiled in an open, normally equiangular spiral with an oval or subquadrate whorl section. The surface is banded by fine, dense, rounded ribbing sectioned by periodically spaced thick and often spinose ribs.
Crioceratities fossils have been found in Lower Cretaceous Hauterevian-Barremanian, sediments in Europe, Africa, Asia, North America and South America.
