Klapperilepis termini (Sannemann, 1955) from the K. crepida Zone at Kadzielnia in the Holy Cross Mountains.

Klapperilepis termini - P₁, P₂ and M  elements.

Diagnoza

Platform of P₁ element with rows of high tubercles on both sides of the ventral blade and prominent, isolated cusp.

Porównanie

Early populations of the species are morphologically transitional to K. crepida and K. robusta, with some elements having only one row of relatively low denticles posterior to the blade, others lacking them completely and differing from associsted K. crepida only in a narrower platform. There is an apparent change within the lineage towards a more and more narrower platform with a stronger separation of its smooth and flat dorsal area and extremely high ridges on both sides of the blade. The ridges do not reach the cusp, which forms an isolated high conical structure in the middle of the element. This change seems to be of much correlative value.
