Dasbergina granulosa (Ziegler, 1962) from the L. styriacus Zone at Ostrówka  in the Holy Cross Mountains.

Diagnoza

The platform of irregularly angular shape ornamented with numerous tubercles, basal cavity forms lobes on both sides of the P₁ element.

Porównanie

This is one of the most robust and largest Famennian conodonts. Mature P₁ elements bear a very wide platform but the conical basal cavity grows to maturity. Some specimens from Kowala and Dzikowiec, with very variable ornamentation and the platform extending far outside the basal cone, but restricted to the center of the element, may be transitional to Dasbergina sp. aff. D. kayseri.
