Nanshiungosaurus is a genus of dinosaur from the Late Cretaceous Period that lived in what is now China. There are two known species: N. brevispinus was discovered in the Yuanpu Formation and N. bohlini was discovered from the Xinminbao Group. Only partial remains have been found which do not include the skull, tail, ribs or limbs. Analysis of this genus is based on the vertebrae and pelvis alone.
At first, this dinosaur was thought to be a strange type of sauropod, but with the subsequent finding from another bone bed, it helped place the dinosaur within its own genus. However, the findings of N. bohlini differ slightly from those of the nominate specimen and it is possible that it may warrant its own genus.
