Discovery and species
The first fossil of Shunosaurus was discovered in 1977 by a group of students, practising paleontological excavation at a road bank. The
The
A proposed second species, S. ziliujingensis, a name mentioned in the Zigong museum guide to indicate a smaller and older form, has never been formally described, and thus remains a nomen nudum.
In 2004 a partial semi-articulated specimen from Jiangyi Township in Yuanmou County was described as the new species Shunosaurus jiangyiensis. It is known from nine cervicals, 15 dorsals, three sacrals, four caudals, both scapulae, the right coracoid and clavicle, the right forelimb lacking the hand, a pubis and ischium and the right hindlimb, found in the upper section of the Middle Jurassic
Description
Shunosaurus was first estimated to be 11 metres (36 ft) long; later and more complete finds indicated a somewhat smaller size. In 2010

Classification
Shunosaurus was originally classified as a member of the Cetiosaurinae; in 1992 Dong assigned it to Shunosaurinae within the Cetiosauridae.[10]
Paleobiology
Its neck length indicates that Shunosaurus was a low browser. The form of its jaws is well-adapted to processing large amounts of coarse plant material.[13]
Shunosaurus accounts for 90% of the fossils found in the Dashanpu fauna, showing it was a dominant and/ or common member of its
