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.Klettgau Formation at Fossilworks.org
Description 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.Jordan et al., 2016
