Yingshanosaurus is a genus of Quadrupedal dinosaur from the Late Jurassic, around 150 million years ago. It was a stegosaurian which lived in what is now China. The type species, Yingshanosaurus jichuanensis, was first mentioned in a 1984 publication by Zhou Shiwu but was not described as a new taxon until 1994.[1][2] A 2006 paper indicates that the holotype, CV OO722, has been lost.[3]

Like all stegosaurians, Yingshanosaurus was an herbivorous dinosaur. It was similar to another stegosaurian, Tuojiangosaurus. Yingshanosaurus had a pair of wing-like spines on its shoulders, which were flat, like the bony plates on its back.
