Glatziella glaucopis (Renz, 1914) from the D. trigonica Zone at Dzikowiec in the Sudetes and Kowala in the Holy Cross Mountains.

Diagnoza

Globose, relatively involute conch; wide whorls with smooth flanks.

Porównanie

This is probably the end-member of the Glatziella lineage. No sign of ribbing is visible on internal moulds and also the areas with preserved shell visible in sections seem to be smooth. Suture can be traced only in the umbonal part of specimen ZPAL AmVII/1040 and septa in a section across the inner whorl of the holotype. It was apparently of simple geometry and does not differ substantially from the sutures of related species from Dzikowiec.
