Jiangjunosaurus is a genus of stegosaurid dinosaur from the Oxfordian-age (Upper Jurassic) Shishugou Formation of the Junggar Basin, Xinjiang, China. Remains including the lower jaw, some skull bones, eleven articulated neck vertebrae, and two plates are known. The type species, J. junggarensis, was described by Chengkai et al.. in 2007.[1] Jiangjunosaurus reached around 6 m (20 ft) in length and may have been a prey item for Yangchuanosaurus.[2]
