Dinosaur is the common term referring to fossils of Saurischian and Ornithischian of the Diapsida subclass. Dinosaurs are a large family of reptiles with 900–1200 genera that lived approximately 65–225 million years ago. They have been studied for nearly 200 years since their first discovery in 1822. China has the largest number of dinosaur fossils in the world, and they are found almost everywhere in the country. Dinosaurs have important research value and are also one of the public’s favourite types of fossils. Hence, they are important tourism resources. China’s geoparks with dinosaurs as the theme are Zigong in Sichuan Province, Jiayin in Heilongjiang Province, Liujiaxia in Gansu Province, Lufeng in Yunnan Province, Chaoyang in Liaoning Province, Yanqing in Beijing, Xixia in Henan and Yun County in Hubei Province (Figs. 19, 20, 21).
