 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.
