The footprints are from 100 million years ago and contain(包括) about 70 Deinonychus prints in four parallel(平行的) tracks. The two-legged dinosaurs are identified by the two claws on their hind feet. "Blue" from the Jurassic World: Fallen Kingdom movie is this kind of dinosaur. The discovery proves for the first time in archeological history that Deinonychus lived in packs(群居). 

Scholars determined that the dinosaurs were about 1 meter long(长) and could run(奔跑) at a speed(速度) of up to 2.4 meters per second. 

The tracks were discovered by fossil hunters in 2015. It proves the area was an ideal habitat since 7 species lived there 100 million years ago, says Xing Lida from the China University of Geosciences.
