3,000 dinosaur footprints, believed to be more than 100 million years old, have been discovered after a three-month excavation at a gully in Zhucheng in the eastern province of Shandong.
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.
Wang Haijun, a senior engineer at the Chinese Academy of Sciences, said the prints faced the same direction which Wang added indicated a possible migration or a panic escape by plant-eating dinosaurs after an attack by predators.
Archeologists have found dinosaur fossils at some 30 sites in Zhucheng, known as "dinosaur city."
The region has seen two major digs since 1964, and experts say the discovery of so many dinosaurs in such a dense area could provide clues on how the animals became extinct millions of years ago. AFP reports that plans are being made to set up a fossil park in the area.
