Löwenstein Formation

Löwenstein Formation
Type Geological formation

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

Dinosaurs

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

Dolichosuchus[3]

D. cristatus[3]

"Tibia."[4]

Actually indeterminate ceratosaur remains.[3]
Procompsognathus
Life restoration of Plateosaurus gracilis, formerly known as Sellosaurus gracilis

Halticosaurus[3]

H. longotarsus[3]

"Mandibular fragment, vertebrae, humerus, illium, femur, metatarsal."[4]

Actually indeterminate ceratosaur remains.[3]

Pachysaurus

P. giganteus

"Partial pedes."[5]

Palaeosaurus[3]

P. diagnosticus [3]

Actually Sellosaurus gracilis remains. Yates assigned the type material of Sellosaurus gracilis to Plateosaurus gracilis [6]

Procompsognathus[3]

P. triassicus[3]

"Partial postcranial skeleton."[7]

Sellosaurus[8]

S. fraasi[3]

Yates assigned the type material of Sellosaurus gracilis to Plateosaurus gracilis [6]

S. gracilis[8]

"[Twenty one] partial skeletons, isolated elements, [three] partial skulls, juvenile to adult."[5]

Yates assigned the type material of Sellosaurus gracilis to Plateosaurus gracilis [6]

Teratosaurus[3]

T. minor[3]

Galton and Benton showed that Teratosaurus is actually a rauisuchian.[9][10]

T. trossingensis[3]

Galton and Benton showed that Teratosaurus is actually a rauisuchian.[9][10]

Thecodontosaurus[3]

T. hermannianus[3]

Thecodontosaurus hermannianus was named by Huene (1905), and then recombined as Sellosaurus hermannianus by Huene (1914). Smith and Pol (2007) recombined it as Plateosaurus gracilis[11]
