Hyperodapedon

Hyperodapedon is a genus of rhynchosaur (a beaked, archosaur-like reptile) from the Triassic period. Scaphonyx, once thought to be a dinosaur, is now known to be based on material from a specimen of Hyperodapedon, making the name Scaphonyx an invalid junior synonym.

Hyperodapedon is known from several species and has been found in many areas of the world, due to the continents being joined together in the supercontinent Pangaea during the Triassic. Fossils from the various species have been identified from South America, Russia, Europe, and India. It was hunted by many predators like Saurosuchus and Prestosuchus.

Description
Hyperodapedon was a heavily built, stocky, animal around 1.3 meters (4.3 ft) in length. Apart from its beak, it had several tows of heavy teeth on each side of the upper jaw, and a single row on each side of the lower jaw, creating a powerful chopping action when it ate. It is believed to have been herbivorous, feeding mainly on seed ferns, and died out when these plants became extinct at the end of the Triassic.
