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]

Archosaurs of the Stubensandstein

Genus | Species | Location | Stratigraphic position | Material | Notes | Images
Aetosaurus | A. feratus

A. crassicauda

|  | Lower  |  |  |
Apatosuchus | A. orbitoangulatus |  | Lower  | "Partial skull"  |  |
Dolichosuchus[3] Dubious  | D. cristatus[3] |  | Middle[3] | "Tibia"[4] | Actually indeterminate coelophysoid remains[3] |
Efraasia | E. minor |  | Lower  |  |  |
Halticosaurus[3] Dubious  | H. longotarsus[3] |  | Middle[3] | "Mandibular fragment, vertebrae, humerus, illium, femur, metatarsal."[4] | Later found to be indeterminate coelophysoid remains[3] |
Liliensternus | L. liliensterni |  |  |  |  |
Mystriosuchus | M. ? |  |  |  |  |
Nicrosaurus | N. kapffiN. meyeri |  | Middle  |  |  |
Paratypothorax | P. andressi |  | Middle  |  |  |
Plateosaurus[5] | P. gracilis[5] |  |

* Middle[3]
* Lower[2]

| "[Twenty one] partial skeletons, isolated elements, [three] partial skulls, juvenile to adult."[6] | Yates assigned the type material of Sellosaurus gracilis to Plateosaurus gracilis [7] |
Procompsognathus[3] | P. triassicus[3] |  | Middle[3] | "Partial postcranial skeleton."[8] |  |

Saltoposuchus | S. connectens S. longipes |  |  |  |  |
TanystrosuchusDubious  | T. posthomus |  | Middle  | " Neck vertebra"  |  |
Teratosaurus[3] | T. suevicus[3] |  | Middle[3] |  | Galton and Benton showed that Teratosaurus is actually a rauisuchian.[9][10] |
