Phlyctaenioidei
Arthrodira (Greek for "jointed neck") is an order of extinct armored, jawed fishes of the class Placodermi that flourished in the Devonian period before their sudden extinction, surviving for about 50 million years and penetrating most marine ecological niches. Arthrodires were the largest and most diverse of all groups of Placoderms. Description Arthrodire placoderms are notable for the movable joint between armor surrounding their heads and bodies. Like all placoderms, they lacked distinct teeth; instead, they used the sharpened edges of a bony plate on their jawbone as a biting surface. The eye sockets are protected by a bony ring, a feature shared by birds and some ichthyosaurs. Early arthrodires, such as the genus ''Arctolepis'', were well-armoured fishes with flattened bodies. The largest member of this group, ''Dunkleosteus'', was a true superpredator of the latest Devonian period, reaching as much as 6 m in length. In contrast, the long-nosed ''Rolfosteus'' measured ju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dicksonosteus
''Dicksonosteus'' is an extinct genus of basal arthrodire, placoderm fish, which lived during the Early Devonian period of Spitsbergen, Norway. ''Dicksonosteus'' was once considered an actinolepid, but is now grouped within the family Phlyctaeniidae.Goujet, D. (1975). Dicksonosteus, un nouvel arthrodire du Dévonien du Spitsberg—Remarques sur le squelette viscéral des Dolichothoraci. ''Colloques internationaux du Centre National de la Recherche Scientifique'', 218, 81-99. Description ''Dicksonosteus'' is considered basal to the arthrodires, the most successful and widespread group of placoderms during the Devonian period notable for the movable joint between the armour sections surrounding their heads and bodies. Its body is wide and flat, and unlike the more robust-jawed arthrodires that would come after it, such as '' Dunkleosteus'' and ''Coccosteus'', its jaws were relatively feeble, suggesting the lifestyle of a benthic fish that subsisted primarily on smaller, softe ...
