Tuojiangosaurus (meaning "Tuo River lizard") was a stgosaur which lived in Late Jurassic China. It is probably the best known Chinese stegosaur, and at 7 metres, was the biggest Chinese stegosaur. It had 2 rows of 24 thin triangular shaped plates, and a thagomizer at the end of the tail. Like other stegosaurs, it was a herbivore.
