Abstract: According to Rieppel (2000) , the genus Nothosaurus contains 8 valid species (N. mirabilis, N. cymatosauroides, N. edingerae, N. haasi, N. giganteus, N. juvenilis, N. marchicus, N. tchernovi) , which were all found in deposits ranging from the lower Anisian to the lower Carnian of the Western Tethyian faunal province (Europe , northern Africa and western Asia) . More recently, a new species, N. jagisteus, was described by Rieppel (2001) based on a partial skeleton from upper Muschelkalk of southern Germany. The first representative of the genus Nothosaurus in the Eastern Tethyian faunal province is Nothosaurus sp. (Rieppel , 1998), represented by a seriously damaged skull and 5 cervical vertebrae (National Geological Museum of China Vm 1308), and previously recognized as a simosaur Shingyisaurus unexpectus by Young C C in 1965. Since the 1990s, many nothosaur specimens have been discovered from the Zhuganpo Member of the Falang Formation in Xingyi , Guizhou and in adjacent areas. The material described in the present paper was collected during the field season of 2001.
