Sweetodina lagoviensis (Dzik, 2006) from the late K. crepida Zone at Łagów in the Holy Cross Mountains.

Diagnoza

M element with elongated processes, the outer process ribbon-like, inner strongly denticulated.

Porównanie

This is probably a local, allopatrically developed species as it is preceded in the Łagów section by the less derived (in respect to M, but not S₃ element morphology) S. monodentata and succeeded by the same species in the region. The bizarre appearance of the M element makes it different from all other Devonian conodonts and only the similarity to F. franconica allows recognition of its affinity.
