Klapperilepis spathula (Schülke, 1995) from the mid K. triangularis Zone at Jabłonna in the Holy Cross Mountains.

Apparatus composition of Klapperilepis spathula.

Diagnoza

P₁ element with long and narrow extension of the posterior lobe, its surface ornamented with irregular tuberculation, P₂ elements flat, without platform, regularly denticulated and with posteriorly bent dorsal process.

Porównanie

Apart from the platform shape, the most characteristic aspect of this and successive species of the lineage is the stepping arrangement of alternating denticles of S₀ to S₂ elements giving them a highly ordered appearance unknown in any other Famennian conodonts. Also P₂ elements, lacking platform and strongly bent, are of much diagnostic value in this lineage.
