In this study, the well-preserved skull of a giant amphibian from the Late Triassic Stuttgart Formation (Schilfsandstein) of Bielefeld-Sieker in NW Germany is described and a new species, Cyclotosaurus buechneri
sp. nov., is erected. Cyclotosaurus buechneri
represents the only unequivocal evidence of Cyclotosaurus
in northern Germany. The amphibian skull was found more than 40 years ago and is well known in Bielefeld and the surrounding areas but has so far never been described.
