Cavusgnathus sp. from the late Visean of Todowa Grząba and Czerna.

Diagnoza

Porównanie

These conodonts show, like coeval Mestognathus, axial symmetry of their P₁ elements being differentiated not only in the wider basal cavities but probably also in a more derived apparatus structure. In the Polish species, which is probably related to C. unicornis Youngquist & Miller, 1949 despite having a much narrower platform, associated finely denticulated ramiform elements with short processes may represent the same apparatus.
