Rodzaj Finiclymenia
Gatunek typowy Opis Diagnosis. — Suture with shallow rounded umbonal lobe; high trapezoidal whorls of the conch; ventrolateral tubercles. Remarks. — Finiclymenia was originally based on the V-shaped apperance of the flank lobe in the only available specimen. The specimens from Kowala and Jabłonna, otherwise indistinguishable from the holotype, show a narrow flank lobe similar to that in species of Kalloclymenia. Otherwise the suture is significantly less derived in other lobes are shallow and round. This suggests that the lineage of F. wocklumensis is rooted deep in the branch of the Gonioclymeniidae being possibly transitional between Costaclymenia and Kalloclymenia. Future findings in strata older than the type horizon are predicted. Synonimy Zasięg czasowy Literatura Dzik, J. 2006.
