Yizhousaurus is a genus of basal sauropodiform dinosaurs which existed in what is now Lower Lufeng Formation, Yunnan Province of southern China during the lower Jurassic period.[1] Identified from a nearly complete and exquisitely preserved skeleton, it is the most complete basal sauropod currently known with intact skull.[1] Although its name was revealed in a 2010 Geological Society of America abstract by Sankar Chatterjee, T. Wang, S.G. Pan, Z. Dong, X.C. Wu, and Paul Upchurch,[1] it wasn't validly named and described until 2018. The type species is Yizhousaurus sunae.[2]
