Possible synonyms Archaeosuchus Archaeosuchus cairncrossi is a dubious species of anteosaur from the Tapinocephalus Assemblage Zone. It was named by Broom in 1905 on the basis of a partial maxilla. It was interpreted as a titanosuchid by Boonstra, but Kammerer determined it was an anteosaur indistinguishable from Anteosaurus and Titanophoneus. As Anteosaurus magnificus appears to be the only valid large anteosaur in the Tapinocephalus Assemblage Zone, Archaeosaurus cairncrossi is very likely to be based on a specimen of it, but due to poor preservation, the specimen lacks any features that would allow the synonymy to be proven. Eccasaurus Eccasaurus priscus is a dubious species of anteosaur from the Tapinocephalus Assemblage Zone. It was named by Robert Broom in 1909 on the basis of a fragmentary skeleton, of which Broom only described the humerus. As with Archaeosuchus cairncrossi, Eccasaurus priscus is very likely to be synonymous with Anteosaurus magnificus. As Eccasaurus was named before Anteosaurus, a petition to the ICZN would be needed to preserve the name Anteosaurus magnificus if the synonymy were to be proven.
