The Löwenstein Formation (Stubensandstein in Baden-Württemberg, Burgsandstein in Bavaria) is a lithostratigraphic formation of the Keuper in Germany. It is underlain by the Mainhardt Formation and overlain by the Trossingen Formation. It dates back to the middle Norian.[1]

Fauna

Theropod tracks and an unnamed herrerasaur genus are known from the Lower Stubensandstein.[2]
