''Erromenosteus'' is a genus of extinct, medium-sized brachythoracid arthrodire placoderm from the Late Frasnian of the Kellwasserkalk facies of Late Devonian Bad Wildungen and Bicken, Germany. The various species had bullet-shaped heads, and curved, crushing jaws. ==Species List== As was mentioned, all known species are from the German Kellwasserkalk facies. Denison (1978) says that the various species need to be revised, as many of the species were originally described as specimens of other species. Obruchev (1932) and Miles (1969) placed ''Leiosteus'' (=''Erromenosteus'') within Pachyosteidae (before Pachyosteidae was merged into Selenosteidae). Now, though, ''Erromenosteus'' is considered a basal member of Dinichthyloidea.
