The Klettgau Formation is a geological formation in Switzerland, It is Late Triassic in age, covering most of the mid to late Norian, the Carnian, and into the Rhaetian, spanning a period of 26-30 million years. The primary environment of deposits was that of a playa, with marine and fluvial intercalations. The lithology is quite variable consisting primarily of fine grained rocks typically claystones and dolocretes, often with sandstone or carbonaic fluvial channel fills.[1] Dinosaur fossils are known from the formation, including those of Plateosaurus, Notatesseraeraptor and Schleitheimia[2][3]
