Qianjiangsaurus

Qianjiangsaurus (meaning "Qianjiang lizard") is an extinct genus of hadrosauroidean ornithopod dinosaurs from the Late Cretaceous Zhengyang Formation of China. The genus contains a single species, Q. changshengi, known from a partial skeleton. Qianjiangsaurus is one of the few hadrosauroids named from south China, and it indicates important fauna connections between similarly aged formations in Mongolia.
