Scaphignathus velifer Helms, 1959 from the C. marginifera Zone at Łagów in the Holy Cross Mountains - P₁ element.

Diagnoza

Icrion in P₁ elements gradually tapering dorsally, with narrow tip.

Porównanie

Alternognathus costatiformis of Matyja (1993), with its virtually equal height of lateral and medial denticles in the icrion and a distinct separation of icrion from the free blade, is so similar to Scaphignathus that it probably belongs in this genus.
