$A reconstruction of Tuebingosaurus maierfritzorum. The cortical bone on the left side of the fossil is fractured into flakes, which can be explained if the carcass was exposed over a long time on the mud, two to four years, before being buried -- in the reconstruction, the animal will fall to its right body side. The reconstruction shows the animal sinking in a mud trap, attacked by a rauisuchian, Teratosaurus, which has also been found in the Trossingen Formation in Baden-Württemberg. In the background, a herd of Plateosaurus trossingensis runs away from the scene. The flora in the swamp is reconstructed based on fossils from the Germanic basin, with shoots of horsetails and ferns covering the swamp and a forest comprising cycads, lycophytes and coniferous plants.
