Tuojiangosaurus wikidino

Illustration of Tuojiangosaurus

Tuojiangosaurus is a stegosaurid dinosaur from the Late Jurassic Period of China.


Tuojiangosaurus was about 7 meters long from head to tail, and weighed approximately 4 tonnes.[1] Like all stegosaurs, it had two rows of plates running down its back. Unlike its better-known relative Stegosaurus, however, its plates were thin and triangular.[2]


Tuojiangosaurus was described in 1977 by Dong Zhiming from the Upper Shaximiao Formation of China. There is one known species, T. multispinus.[3]



Based on its vertebrae, it was unlikely that Tuojiangosaurus could rear up on its hind legs, like Stegosaurus could. Because of this, it probably fed on low-growing ground vegetation.[4]
