Sanpasaurus ("Sanpa lizard") is a poorly known sauropod dinosaur from the Early Jurassic of Sichuan, China. The type species, S. yaoi, was described by Chung Chien Young, in 1944. The type remains, IVPP V.156, consists of 20 vertebrae, scapulae, forelimbs, and some hindlimb bones.[1] Initially reported as an ornithopod ornithischian,[1] this specimen was unambiguously referred to Sauropoda[2][3] in 2016 by McPhee et al.[4]
