Erromenosteus


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 says that the various species need to be revised, as many of the species were originally described as specimens of other species. Obruchev and Miles placed Leiosteus within Pachyosteidae. Now, though, Erromenosteus is considered a basal member of Dinichthyloidea.

''Erromenosteus''

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