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.

Leiosteus
These species were originally classified within Leiosteus before the genus was synonymized with Erromenosteus.
