Abstract
The holotype and only known specimen of Shingyisaurus unexpectus Young, 1965, from the Middle Triassic (Anisian) of China is redescribed. Originally identified as a simosaur, the incomplete and poorly preserved skull is instead referable to the genus Nothosaurus. Consequently, simosaurs remain unknown from the western Pacific faunal province. The occurrence of Nothosaurus in the Anisian of China provides circumstantial evidence for Asiatic affinities of the Nothosauridae.
