Diagnoza Platform of P1 elements with prominent oblique crests in the ventral part. Porównanie Populations of this species show a rather stable morphology, similar to co-occurring P. communis, but unlike early populations of the latter. In a few samples from the P. jugosus Zone at Kowala rare juvenile specimens of a polygnathid have been found of the kind identified with the Tournaisian Polygnathus margininvolutus Gedik, 1969. In the triangular shape of the strongly concave thin platform these elements are similar to juveniles of P. semicostatus. Similar forms occur in the Tournaisian, where they probably represent juveniles of Neopolygnathus vogesi (Dzik, 1997). The available material is too small to be sure of their nature.
