  Klettgau Formation (Switzerland) | |
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.[1]
The primary depositional environment 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 carbonatic fluvial channel fills.[2]
Dinosaur fossils are known from the formation, including those of Plateosaurus, Notatesseraeraptor frickensis and Schleitheimia[3][4]
The following other fossils were found in the formation:[1]
