In appearance, their bodies were sharklike, with broad, fleshy paired pectoral fins, pelvic fins and an anal fin, as well as a single dorsal fin. In many advanced arthrodires, the tail was naked, but in more primitive forms the tail was covered with scales that didn’t overlap, that were small polygonal plates of bone with an ornamentation of.

  Abstract. Three new monotypic genera of eubrachythorarid arthrodires with crushing toothplates are described from the Upper Devonian Gogo Formation of Western Australia as Bruntonichthys multidens gen. et sp. nov., Bullerichthys fascidens gen. et sp. nov. and Kendrickkhthys cavemosus gen. et sp. nov. Their structure and relationships are discussed within the framework Cited by:   The unique specimen of Coccosteus angustus Traquair, from the Lower Devonian Hunsrückschiefer of Germany, is redescribed and referred to Gemuendenaspis Previously unrecorded details of its morphology and a reconstruction are given. A review of the proposed patterns for the ancestral morphotype in the gnathostome pectoral fin suggests that the underlying models have driven the interpretation of anatomy.

  Abstract. A brief account and new restorations of the Scottish Middle Old Red Sandstone fish Rhamphodopsis are given, based largely on new material from Edderton, Ross-shire. The Edderton material is of the species Rhamphodopsis threiplandi Watson, previously known only from A chanarras, Caithness.
