The footprints, believed to be more than 100 million years old, were discovered after a three-month excavation at a gully in Zhucheng in the eastern province of Shandong, the Xinhua news agency reported.
The prints range from 10 to 80 centimetres (four to 32 inches) in length, and belonged to at least six different kinds of dinosaurs, including tyrannosaurs, the report said Saturday.
Wang Haijun, a senior engineer at the Chinese Academy of Sciences, said the prints faced the same direction, Xinhua said.
This indicated a possible migration or a panic escape by plant-eating dinosaurs after an attack by predators, Wang added.
Archeologists have found dinosaur fossils at some 30 sites in Zhucheng, known as “dinosaur city.”
