Paleontologists Robert M. Sullivan and Spencer G. Lucas question the presence of Allognathosuchus in the formation because the referred remains were so scant and Allognathosuchus has never been reported in Cretaceous strata previously. They regard the referred scute as belonging to an indeterminate alligatoroid.
