Walterosteus is an extinct genus of small selenosteid arthrodire placoderms known from the Upper Frasnian Kellwasserkalk facies of Late Devonian Germany[1]: 96 and Morocco.[2]
Walterosteus is very similar to the other Kellwasserkalk selenosteids. This similarity lead Denison (1978) to synonymize the genus, together with Ottonosteus (O. jaekeli = E. hermanni), into Enseosteus, claiming that the former two genera are too similar to Enseosteus to merit separate genus status.[1] Rücklin (2011) agrees with Denison's synonymizing of Ottonosteus, but rejects Denison's synonymization of Walterosteus, claiming how Walterosteus has a contact between the rostral plate and the pineal plate, which Enseosteus does not.[2]
