Taxonomy

Chungkingosaurus jiangbeiensis was named by Dong et al. (1983). Its type specimen is CV 00206, a partial skeleton, and it is a 3D body fossil. Its type locality is Maoershi, Jiangbei, which is in a Bathonian/Callovian terrestrial horizon in the Shaximiao Formation of China. It is the type species of Chungkingosaurus. It was considered monophyletic by Maidment and Wei (2006).

Diagnosis

Reference	Diagnosis
S. C. R. Maidment and G. Wei 2006	Differs from all other stegosaurs in that all of the sacral ribs are angled strongly posterolaterally. The anterior iliac processes do not diverge strongly from the parasagittal plane.
S. C. R. Maidment et al. 2008	Differs from all other stegosaurs in possessing the following unique character combination: sacral ribs are angled strongly posterolaterally. The anterior iliac processes do not diverge strongly from the parasagittal plane.
