Diagnoza

Porównanie

Two specimen from the Czarnocki’s collection are similar to Gundolficeras from the much older strata at the same locality but differ in having a rather wide ventrolateral saddle and shallow dorsal lobe. The first feature is even more apparent in G. delepinei from the late Famennian of Algeria , which may represent the end member of the same lineage.
