The genus is characterized by pustulose ornamentation on a wide, flat-topped carina. It originated in the earliest Permian as S. expansus from Diplognathodus edentulus.

Sweetognathus forms a species complex.

The genus is named after paleontologist Walter C. Sweet.

It has been found that recurrent parallel species pairs have occurred throughout Sweetognathus evolution between populations originating in Bolivia, the Mid-Western Unitied States, and Russia. Parallelisms have been found to occur in the denticle morphologies of their platform elements.
