A few days ago, Xuanhua District, Zhangjiakou City, Hebei Province found more than 9,000 square meters of dinosaur footprint fossils. After counting, there were more than 4,300 dinosaur footprints. Multiple footprints are done. Geological investigators have shown the geological measurement of the scene. The rock layer where the dinosaurs are in the rock layer have been 150 million years old, but the footprints at the scene are very clear. There are 4 types of dinosaur footprints, and 1 case of dinosaur footprint is found. Xing Lida, an associate professor at China University of Geosciences, said, "This is such a large -scale footprint like the era of Jurassic to Baiji Ji, and it must be the first in our country. It can reach more than fifteen meters, and the body dinosaurs can be about four to five meters long. "

Experts speculate that the scene of the footprints had a large number of forests and water sources more than 100 million years ago, so there are a lot of plant dinosaurs and carnivorous dinosaurs. The fossil formed by the footprints left when the surface walks moderately. Dinosaurs are more distinctive and significant than dinosaur fossils and dinosaur egg fossils. And these intact dinosaur footprints also fill the "blank areas" between the two major middle generations of "Yanliao" and "Rehe" in Hebei Province, which is extremely important for studying the correlation between the two major biological communities. value.
