Sinopliosaurus

Young 1944

Sinopliosaurus is a dubious genus of pliosauroid plesiosaur. It lived during the Aptian and Albian stages of the Early Cretaceous 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. One species, "S." fusuiensis, was later shown to be based on teeth from a spinosaurid theropod dinosaur which is now known as Siamosaurus. S. weiyuanensis was considered as a freshwater plesiosaur.
