Xuanhua District, Zhangjiakou City, Hebei Province found more than 9,000 square metersAnd newly discovered a genus of dinosaur footprints.Experts estimate that this is currently China's largest dinosaur footprint.not According to CCTV News client reported on Friday (July 8), geological investigators have shown the geological measurement of the scene that the rock layer where the dinosaur footprint is now has 150 million years old, but the footprints at the sceneThe preservation is very clear.not Xing Lida, an associate professor at the Chinese University of Geosciences, said that the footprint originated from the era of Jurassic to the Baiji Period. Such a large -scale footprint is currently ranked first in China.not Some of these footprints are approximately circular, some are similar to the shape of animal claws, and multiple footprints are in line.Xing Lida said: "From the footprint of the scene, infer the length of the planting dinosaur can reach more than fifteen meters long, and the body dinosaur body can reach about four to five meters long."
identification and classification of traces through experts' identification and classification of tracesDetective, there are four types of dinosaur footprints, and one example of the new dinosaur footprint is found.not Experts speculated 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.not The formation of dinosaur footprints is very harsh. It is a fossil formed by the footprints left by the dinosaurs when walking on the surface with a moderate surface.Dinosaurs are more distinctive and significant than dinosaur fossils and dinosaur egg fossils.not These intact dinosaur footprints fill the "blank areas" of the intermittent time between the Yanliao biological group and the Rehe biological group in Hebei Province. It has extremely important value for research on the correlation between the two major biological communities.Essencenot Previously, China Paleochians claimingIt has an area of more than 9,000 square meters and has at least 933 footprints.
