Discovery and namingEdit

The type species Zizhongosaurus chuanchengensis was named in 1983 by Dong ZhimingZhou Shiwu and Zhang Yihong. The generic name is derived from Zizhong Countyin Sichuan Province. The specific name refers to the town of Chuancheng.

The type specimens consist of three syntypes: V9067.1 is a partial dorsal vertebra; V9067.2 is a humerus or upper arm; and V9067.3 is a pubis. All specimens likely were part of a single skeleton, collected from the Ziliujing FormationZizhongosaurus was described as a small species.[1]

In 1999 Li Kui mentioned a second species: Zizhongosaurus huangshibanensis[2] but this has remained an undescribed nomen nudum.

ClassificationEdit

Zizhongosaurus was originally assigned to the Cetiosaurinae but later authors have placed it in either the Vulcanodontidae, as a relative of Barapasaurus, or the Shunosaurinae. It is today often considered a nomen dubium.
