Chungkingosaurus was a genus of herbivorous dinosaurs that originated in late Jurassic Asia. The name means "Chongqing lizard", and refers to the place where the fossils were first discovered. It was a member of the Stegosauria family. It was unearthed in 1977 and described in 1983 by paleontologists Dong Zhiming, Zhou Shiwu and Chang Yihong.
Chungkingosaurus had small, narrow, thick plates arranged in two parallel rows along its back. It has four twin pairs of thagomizers or tail spikes. The tail spikes are used to defend against much larger predators. Compared to stegosaurs, it was quite primitive based on its hips and humerus (upper arm bone). It was one of the smallest stegosaurs, with a length of less than four meters, according to Dong e.a. It has a deep snout, front lower jaws and non-overlapping teeth with less pronounced denticles. Chungkingosaurus eats terrestrial herbivores like other stegosaurs.
Chungkingosaurus reached a length of up to 4 - 5 m and weighed 1,000 - 3,000 kg.
