Acutimitoceras guerichi (Frech, 1902) probably from the D. trigonica Zone at Dzikowiec in the Sudetes.

Diagnoza

Large mature conch with parabolic venter in cross section.

Porównanie

The holotype does not show any traces of growth increments and only its large size makes it different from other Dzikowiec prionoceratids. The discoidal conch shape suggests that this is a member of the lineage leading to acute Tournaisian species.
