Qijianglong is a genus of sauropod dinosaur that lived in China during the late Jurassic. At the time of writing the genus is only known from a single juvenile, yet this juvenile is already fifteen meters long. It is uncertain how big Qijianglong could grow, but at fifteen meters just for a juvenile, larger adults may have approached or even exceeded twenty meters. As a mamenchisaurid sauropod, Qijianglong would have had a proportionately long neck.
