A NEW RAUISUCHIAN REPTILE (DIAPSIDA: ARCHOSAURIA) FROM THE LATE TRIASSIC OF POLAND

A crushed rauisuchian skull and several vertebrae belonging to a single individual have been found in the Upper Triassic strata at Krasiejów, Poland, probably corresponding in age to the Lehrberg Beds (late Carnian) of Baden-Württemberg, Germany. A maxilla of Teratosaurus suevicus from the early Nor...

Summary:A crushed rauisuchian skull and several vertebrae belonging to a single individual have been found in the Upper Triassic strata at Krasiejów, Poland, probably corresponding in age to the Lehrberg Beds (late Carnian) of Baden-Württemberg, Germany. A maxilla of Teratosaurus suevicus from the early Norian (Stubensandstein at Heslach) is similar to that of the Krasiejów specimen. The dorsal process of the maxilla is more oblique than in T. suevicus, the medial anterior foramen is set on the medial side, contrary to being exposed anteriorly in T. suevicus, and foramina for replacement teeth are not connected by a dental groove and are set in straight line. A new species of Teratosaurus is proposed to accommodate the Polish material, and a more complete diagnosis of the genus is presented.
