Les vertébrés dévoniens de l'Iran central: IV: Arthrodires et ptyctodontes

The Upper Devonian localities of the Kerman and Tabas area yielded numerous brachythoracid arthrodire remains, referred here mainly to Golshanichthys asiatica nov. gen., nov. sp., and Holonema cf. radiatumObrouchev. Some specimens are suggestive of species belonging to the genera Plourdosteus, Eastmanosteus and Aspidichthys. G. asiatica is a primitive dinichthyid characterized by e.g. very deep posterior and anterior embayments of the central plates.Some ptyctodontid tooth plates of «Rhynchodus and «Ptyctodus type have been found in the Frasnian and Famennian.     

Un nouvel horizon à vertébrés dans la coupe-type de la formation de Khush-Yeilagh (Dévonien Moyen), Alborz oriental,Mazenderan, Iran

Some vertebrate remains, referred to an arthrodire, a ptyctodont, a struniiform, and an actinopterygian respectively, have been discovered in a marine horizon of the type section of the Khush-Yeilagh Formation, in eastern Alborz (Mazenderan, Iran). An arthrodire skull-roof fragment from this horizon may be referred to a buchanosteidae, a group known hitherto only from the Lower Devonian of Australia and China.
