…an extinct genus of rhynchosaurs (a group of archosaur-like reptiles) that lived during the late Triassic period. Hyperodapedon was a heavily built animal and like other rhynchosaurs it had a ‘beak’ with a set of rodent-like teeth, it also had several rows of teeth on its upper jaws and a single row on its lower jaw. These teeth allowed it to create a powerful chopping action. It used these chopping teeth to feed on Triassic plants like seed ferns. Their decline has been attributed to the extinction of these plants at the end of the Triassic.
