Age, distribution, and phylogeny of the peculiar Late Devonian ammonoid Soliclymenia

Dieter Korn, Robert Niedźwiedzki, Jan Bartosz Posieczek


New records of the triangularly coiled Soliclymenia paradoxa (MÜNSTER, 1839) from Dzikowiec (Sudetes, Poland) allow the study of intraspecific variability. It can be demonstrated that at least three species within the genus Soliclymenia can be separated. The genus has a limited stratigraphic distribution within the “Wocklumeria Stufe” of the Late Devonian, but a wide geographic range within the tropical seas.
