Diagnoza

The oldest identifiable ammonoids in the Dzikowiec section have been found in sample Dz-28 with   Pinacognathus sulcatus, thus of earliest Tournaisian age. Only one side of a juvenile, relatively compressed conch is preserved which fits, in general shape and surface ornamentation, M. hoennense.Its type horizon, Oberrodinghausen Bed 2, is much younger than the Dzikowiec stratum.
