Allocrioceras is an ammonoid cephalopod from the Turonian to Santonian stages of the Late Cretaceous,[1] included in the turrilitoid family Anisoceratidae. Its shell is strongly ribbed and is in the form of a widely open spiral.
After its 1907 discovery, the species A. hazzardi was erroneously classified as Crioceras latus by Udden. A later 1928 revision by Adkins removed it from the species C. latus while keeping it as a member of the genus Crioceras. In 1963, Young gave the species its final classification in a new genus, Allocrioceras, originally defined by Spath in 1926.[1]
