Enseosteus
''Enseosteus'' is a genus of small selenosteid arthrodire placoderms known from the Upper Frasnian Kellwasserkalk facies of Late Devonian Germany and Morocco. ''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.〔 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.〔 ==References==
