Stratigraphy comments: 2.1 m below the Rhät, upper Middle Keuper; referred to the Upper "Zanclodon" Knollenmergel. The Knollenmergel of northern Switzerland is correlated with the Trossingen Formation of southern Germany (see Deutsche Stratigraphische Kommission 2005, Cour. Forsch.-Inst. Senckenberg, Table 6.2, pg. 272) which is considered late Norian (Sevatian) in age (Deutsche Stratigraphische Kommission 2005, Cour. Forsch.-Inst. Senckenberg)

upper Middle Keuper, upper Norian, now = Trossingen Fm. and thus late Norian to Rhaetian age
