When they described the holotype in 1983, Dong et al. also assigned three other specimens to Chungkingosaurus, two of which are from the same area, but none were assigned to the name-bearing Chungkingosaurus jiangbeiensis nor given their own specific names, mainly because their remains were too fragmentary. Chungkingosaurus sp. 1 (CV 00207) from the Upper Shaximiao Formation at Ouling Public Park in Chungking, was almost five meters long and had one less fused hip vertebrae than Chungkingosaurus jiangbeiensis. Chungkingosaurus sp. 2 (CV 00205) from the Upper Shaximiao Formation at Huayibo, central Chungking, was over five meters long and had a slightly higher thigh-to-upper arm ratio than the former two specimens. Chungkingosaurus sp. 3. (CV 00208) from the Upper Shaximiao Formation at Longshi, Hechuan County, Sichuan, is one of the rare instances of a stegosaur being discovered with tail spikes still attached to its tail. There were four pairs originally, though one pair was lost due to weathering according to Yihong Zhang who excavated the remains. The base of each pair span three tail vertebrae. In 2014, Roman Ulansky named CV 00205 Chungkingosaurus giganticus and CV 00207 Chungkingosaurus magnus, but by this point, his serial self-publishing was getting on palaeontologists' nerves. Maidment and Wei had already assigned both specimens to Chungkingosaurus jiangbeiensis in 2006 and the universal opinion is that's where they belong. As with the holotype, the whereabouts of much of this material, plus the entirety of CV 00208 (sp. 3), is currently a mystery.
