Röt Formation


The Röt Formation or Rötton Formation, or Upper Buntsandstein, is a geologic formation of the Buntsandstein in Germany. It preserves fossils dating back to the Middle Triassic Epoch. 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.
