Enseosteus is an extinct genus of small selenosteid arthrodire placoderms known from the Upper Frasnian Kellwasserkalk facies of Late Devonian Germany[1] and Morocco.[2]

Enseosteus is very similar to the other Kellwasserkalk selenosteids, though, the type species, E. jaekelli, has a bulbous, knob-shaped rostrum. Denison (1978) synonymizes the genera Ottonosteus (O. jaekeli = E. hermanni) and Walterosteus with Enseosteus, claiming that the 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]
