... of that of the Upper Ordovician of Baltoscandia. Oenonites , Vistulella , Mochtyella and the enigmatic ‘ Xanioprion ’ represent the most common genera, whereas Pteropelta , Protarabellites ?, Atraktoprion and Xanioprion are considerably more rare. The assemblage differs from coeval ones particularly in its poorly...

... Arabellites auburnensis Charletta and Boyer, 1974 . Cook and Turner (1993) described a Devonian species from Queensland and assigned it to Arabellites (using the emended diagnosis of Sylvester, 1959 ). More recently, both Arabellites and Atraktoprion have been used for typical prionognath type...
