Stephanodus is a form genus of extinct fossil ray-finned fish, referring to the hook-shaped pharyngeal teeth present on the branchial arch of pycnodonts.[1]

Some species placed in this genus were previously assigned to the fossil genus Grypodon Hay, 1899, which itself was created to replace the former genus name Ancistrodon Debey, 1849 due to it being preoccupied by a junior synonym of the snake genus Agkistrodon.[2][3] Eotrigonodon is likely also another synonym for the genus[1], but this is not completely certain.[2]

The following species are placed in this genus:[4][5][6]

The alleged species S. armatus (Gervais, 1852) from the middle Eocene of Belgium and S. vicentinus (Dames, 1883) from the Oligocene of Italy likely represent indeterminate tetraodontiform teeth.[7]
