The Röt Formation or Rötton Formation (German for Röt Shale), or Upper Buntsandstein, is a geologic formation of the Buntsandstein in Germany. It preserves fossils dating back to the Middle Triassic Epoch (Anisian or Aegean or Bithynian in the regional stratigraphy). The formation overlies the Plattenstein and Solling Formations and is overlain by the Jena Formation.
The limestones, mudstones, shales and sandstones of the formation, deposited in a shallow marine environment, have provided fossils of early archosaurs, temnospondyls, fish and insects.
