Supradapedon is an extinct genus of hyperodapedontine rhynchosaur from mid-late Triassic deposits of Tanganyika Territory, Tanzania. It is known from the holotype SAM-11704. The holotype and only specimen of Supradapedon was first assigned to a species of Scaphonyx (now considered to be a nomen dubium), Scaphonyx stockleyi.[1] This species was reassigned to its own genus by Sankar Chatterjee in 1980 and the type species is Supradapedon stockleyi.[2] One study, Langer et al. (2000), concluded that Supradapedon is a synonym of Hyperodepedon and referred it to Hyperodepedon sp.[3] However, the provisional validity of this genus has been commonly accepted since.[4][5][6]
