The new genus Walliserognathus and the origin of Polygnathoides siluricus (Conodonta, Silurian); pp. 113–121

(Full article in PDF format) https://doi.org/10.3176/earth.2018.08


Authors

Carlo Corradini, Maria G. Corriga

Abstract

The new genus Walliserognathus is described to host the species posthamatus (Walliser). The genus is monospecific. The shape of P1 and P2 elements of Walliserognathus posthamatus, characterized by a small platform along the whole elements, and its stratigraphic distribution limited to the Ancoradella ploeckensis Zone suggest that the species may have been the bridge in the phylogenesis from Wurmiella to Polygnathoides.

Keywords

conodonts, taxonomy, phylogeny, Silurian, Walliserognathus n. gen., Polygnathoides siluricus.
