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]

Vertebrate fauna

Theropod tracks and an unnamed herrerasaur genus are known from the Lower Stubensandstein.[3]

Archosaurs of the Stubensandstein
Genus	Species	Location	Stratigraphic position	Material	Notes	Images
Dolichosuchus[4]	D. cristatus[4]		Middle[4]	"Tibia"[5]	Actually indeterminate coelophysoid remains[4]
Halticosaurus[4]	H. longotarsus[4]		Middle[4]	"Mandibular fragment, vertebrae, humerus, illium, femur, metatarsal."[5]	Later found to be indeterminate coelophysoid remains[4]
Plateosaurus[6]	P. gracilis[6]		Middle[4] Lower[3]	"[Twenty one] partial skeletons, isolated elements, [three] partial skulls, juvenile to adult."[7]	Yates assigned the type material of Sellosaurus gracilis to Plateosaurus gracilis [8]
Plateosaurus[6]	P. trossingensis				Type species.
Procompsognathus[4]	P. triassicus[4]		Middle[4]	"Partial postcranial skeleton."[9]
Teratosaurus[4]	T. minor[4]		Middle[4]		Galton and Benton showed that Teratosaurus is actually a rauisuchian.[10][11]
Teratosaurus[4]	T. trossingensis[4]		Middle[4]		Galton and Benton showed that Teratosaurus is actually a rauisuchian.[10][11]
