The Fort Crittenden Formation is a geological formation in Arizona whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.[1]
Paleontologists Robert M. Sullivan and Spencer G. Lucas questioned the referral to this specimen to Allognathosuchus in the formation because the referred remains were so scant and Allognathosuchus is confined to the Paleogene. They regarded the referred scute as belonging to an indeterminate alligatoroid.
