Yingshanosaurus

"Yingshanosaurus" is the informal name given to 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 suggested "type species", coined by Zhou in 1984,[1] is "Yingshanosaurus jichuanensis", but this is only an informal designation, as the genus has not yet been fully described. A 2006 paper indicates that the only fossil specimen has been lost.[2]

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.
