Remarks
The specimen known as “GPIT Aixheim” was tentatively classified as Teratosaurus suevicus by von Huene (von Huene 1905: 345–349; 1907: 158–168) (species 28 in Fig. 3). However, the maxilla NHMUK PV OR 38646, which is the holotype of Teratosaurus suevicus, has been identified as a rauisuchian (Brusatte et al. 2009). A similar situation occurred with “GPIT 18392”, also referred to as Teratosaurus suevicus (von Huene 1915). Subsequently, both “GPIT Aixheim” and “GPIT 18392” were reclassified as Plateosaurus gracilis (Sellosaurus gracilis in Hungerbühler 1998; Plateosaurus gracilis in Yates 2003) (species 20 in Fig. 3). “GPIT 18318a” is also referred to as cf. Plateosaurus gracilis, as it has been included as a part of Pl. gracilis following Yates (2003).
