==Classification==
''Suchodus'' is a member of the metriorhynchid subfamily called Geosaurinae and the derived tribe Geosaurini. Members were generally large marine predators, adapted to open-ocean life with streamlined bodies, powerful tails, and long, robust jaws lined with sharp teeth. ''Suchodus'' is most closely related to the genus ''Plesiosuchus'', both forming the group Plesiosuchina.
