==Description== thumb|left|Size comparison According to Dong e.a. the Chungkingosaurus jiangbeiensis holotype was one of the smallest stegosaurs with a length of less than four metres, even though it was apparently an adult, judging by the ossification of the sacrum. Chungkingosaurus sp. 1 was estimated at five metres; Chungkingosaurus sp. 2 was seen as longer than five metres. Dong e.a. indicated that Chungkingosaurus strongly resembled Tuojiangosaurus, found in the same formation, in many anatomical details. Chungkingosaurus was different in its smaller size, deeper snout and front lower jaws (resulting in a relatively high and narrow skull), and non-overlapping teeth with less pronounced denticles.
