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
- Ceratodus elegans Vollrath, 1923, a lungfish from the Stubensandstein[2]
Archosaurs
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] | ||
| Efraasia | E. minor | Lower |  | |||
| 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] | "[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] | |||
| P. trossingensis | Type species. | |||||
| Procompsognathus[4] | P. triassicus[4] | Middle[4] | "Partial postcranial skeleton."[9] |  | ||
| Teratosaurus[4] | T. suevicus[4] | Middle[4] | Galton and Benton showed that Teratosaurus is actually a rauisuchian.[10][11] |  | ||
