Elementy aparatu z Płucek koło Łagowa, wczesny famen (Dzik 2006).

Rekonstrukcja składu aparatu (Dzik 2006)

Diagnoza

From its abcestor, K. ultima, differs in more elongated P₁ elements and M elements usually with relatively wide angle between processes, from successors of various lineages in underived, lambda-shaped M elements.

Porównanie

A variable species, both in respect to the outline of platform in P₁ elements, which ranges from that typical to K. ultima to that of early species of Palmatolepis, but also in the prominence of the cusp and curvature of P₂ elements. The mean value of elongation index of the P₁ elements is distinctly higher than in K. ultima, remaining elements of the apparatus being hardly distinguishable. In fact, to distinguish these chronospecies a large sample is needed and single elements are of little taxonomic value. Some late populations show robust denticulation of ramiform elements and widely angular processes of the M element

Autekologia
