Wangosaurus is an extinct genus of basal eosauropterygian, either a pisotosauroid or a nothosaur, known from the Middle Triassic (late Ladinian stage) Falang Formation of Xingyi in Guizhou Province, southwestern China. It contains a single species, Wangosaurus brevirostris, first described and named by Le-Tian Ma, Da-Yong Jiang, Olivier Rieppel, Ryosuke Motani and Andrea Tintori in 2015. The specific name brevirostris comes from Greek for "short snout". It is known solely from its holotype, a nearly complete and articulated skeleton measuring 2.2 m (7.2 ft) long (without only the rear part of its tail).
