Yingshanosaurus jichuanensis

Yingshanosaurus is a Jurassic stegosaur that is comparable in general shape to its close Asian relative Tuojiangosaurus, though a tad smaller, and sports a wing-shaped spine on each shoulder which are as slender as the plates on its back.

Its name is mostly seen enclosed in quotation marks which is what authors do with critters that lack an official description. And the reason being; its only outing in the literature was courtesy of a Children's dinosaur book written in Chinese, which is far from a scientific medium. Or so we were led to believe.

Actually, Yingshanosaurus was coined by Zhou Shiwu during a lecture of the Middle Jurassic Dashampu fauna at a paleontological congress in Toulouse in 1985 which, although published a year later, lacked a description sufficient enough to drag it into the realms of officialdom. However, Zhu Songlin fully described the animal in an official scientific paper in 1994, which slipped almost all Western eyes because it's also in Chinese. But this document is proving elusive, and the only known specimen of Yingshanosaurus has apparently been misplaced, so what we now know may be all we ever know.
(Yingshan lizard from Jichuan)Etymology
Yingshanosaurus is derived from the Chinese "ying" (Latinised form of "jing", meaning "gold") and "shan" (mountain), for the the County of Jingshan (Golden Hill) where it was discovered, and the Greek "sauros" (lizard).
The species epithet, jichuanensis, means "from Jichuan Town" in Latin.
Discovery
The remains of Yingshanosaurus were discovered in the Upper Shaximiao (Shangshaximiao) Formation, Jichuan Town, Yingshan County, Sichuan, China, by a Wan Jihou-led expedition in 1983. The holotype (CV OO722) is the partial skeleton and fragmentary skull of an adult individual.
