Polymorphodon is an extinct genus of doswelliid archosauriform reptile from the Middle Triassic of Germany. The only known species is Polymorphodon adorfi, discovered in Lower Keuper (Erfurt Formation) deposits at a quarry in Eschenau, Germany. Polymorphodon is notable for its heterodont dentition, with long, conical premaxillary teeth followed by thin maxillary teeth with large serrations. Maxillary teeth near the back of the mouth are short and leaf-shaped, similar to those of some living and extinct reptiles with a herbivorous or omnivorous diet. This may suggest that Polymorphodons diet included some plants, a rarity among basal archosauriforms, most of which are carnivores.
