Diplognathodus Explained

Diplognathodus is an extinct genus of conodonts in the family Anchignathodontidae.^{[1] [2]} Specimens are found in Carboniferous^[3] and Permian formations.

The genus Sweetognathus originated in the earliest Permian as S. expansus from Diplognathodus edentulus.^[4]

Diplognathodus ellesmerensis has been proposed as a marker of the Moscovian, in the Pennsylvanian age of the Carboniferous.
