Qijianglong

Qijianglong is a genus of herbivorous mamenchisaurid sauropod dinosaurs. It is known from the Suining Formation of China, which is of a debated age (reported as Late Jurassic or Early Cretaceous using different methods). The genus contains a single species, Qijianglong guokr, known from a partial skeleton including cranial bones, most of the neck and tail, and other associated elements.

==Discovery== A vertebra of Qijianglong was first discovered in the early 1990s by farmer Cai Changming of Heba village, Sichuan, in his backyard. Work at a nearby construction site at Qijiang District uncovered a rich fossil quarry in 2006. Its excavation caused an examination of the earlier find which led to the discovery of a skeleton. In 2015, the type species Qijianglong guokr was named and described by Xing Lida (China University of Geosciences), Tetsuto Miyashita (University of Alberta), Zhang Jianping, Li Daqing, Ye Yong (Zigong Dinosaur Museum), Toru Sekiya (Fukui Prefectural Dinosaur Museum), Wang Fengping and Philip John Currie. The generic name combines the district Qijiang with Mandarin long, "dragon". The specific name guokr, "nutshell", is that of a Chinese scientific social network.
