Sinopliosaurus (meaning "Chinese more lizard") is a dubious genus of pliosauroid plesiosaur.[1] It lived during the Aptian and Albian stages of the Early Cretaceous[2] (disputed Sinopliosaurus remains have been dated to the Toarcian age and were found in the Ziliujing Formation)[3] of the People's Republic of China - its exact age is unknown. The type species, Sinopliosaurus weiyuanensis, was named and described in 1944 by Yang Zhongjian.[3] One species, "S." fusuiensis, was later shown to be based on teeth from a spinosaurid theropod dinosaur which is now known as Siamosaurus.[1] S. weiyuanensis was considered as a freshwater plesiosaur.[4]
