Meaning of name: Qianjiangsaurus = Qianjiang lizard [in Greek]; changshengi = for Wang Changsheng [the first to formally report Cretaceous dinosaur fossils from Chongqing]

Age: Late Cretaceous (more precise age uncertain, but probably sometime within the Campanian–Maastrichtian)

Where found: Zhengyang Formation, Chongqing, China

How much is known: Partial skeleton of one individual, including parts of the skull, hips, and hindlimbs.

Notes: Qianjiangsaurus was a hadrosauroid, closely related to but not a member of the "core group" of duck-billed dinosaurs (hadrosaurids). Its overall anatomy is typical for a non-hadrosaurid hadrosauroid, but it also exhibits some features more commonly found in true hadrosaurids. It is estimated to have been about 8 m long in total body length.
