Chengde surprised to see dinosaur footprints. The summer resort is actually a Jurassic Park
Abstract: the dinosaur evolution records in North China are basically continuous, from Yanliao biota to Tuchengzi footprint fauna, and then to Rehe biota
Jiefang Daily & middot; Shangguan news reporter learned that on December 6, 2019, Chinese, American and Australian scientists announced that their research team had completed the study of dinosaur footprints in Chengde, Hebei Province. Surprisingly, most of the footprints are distributed on the ground of Chengde summer resort, a world-famous Chinese royal garden. It is a rare case of the combination of paleontological remains and fossils and human history in the world. These dinosaur footprints are large and well preserved, which is of great value to study the evolution of dinosaurs, and is of great significance to further explore dinosaur behavior and living environment, so as to restore the paleoenvironment and climate change in the geological period of the region.
The research was led by Xing Lida, associate professor of China University of Geosciences (Beijing), and jointly studied by Professor Martin & middot; lockley, curator of footprint Museum of University of Colorado (Denver) and Anthony & middot; romiliobo of University of Queensland, Australia. The paper was published in the internationally renowned paleontological Journal Cretaceous research.
Represented by hairy dinosaurs, primitive mammals and angiosperms, Yanliao biota and Rehe biota in Northeast China are world-famous. The former is about 167 million years ago and the latter is about 135 million years ago. There is a huge gap in vertebrate fossil records between the two biota. From Yanliao biota to Rehe biota, this long change is recorded in Tuchengzi Formation. At present, only skeletal fossils of Chaoyang dragon, Xuanhua Horned Dragon and Brachiosaurus have been found. A large number of dinosaur footprints have been found in Tucheng formation, which is an important supplement to the evolution of fauna. Among them, Hebei Chengde has a large number of records. Chengde, Hebei Province is located in the northeast of Hebei Province, with Beijing and Tianjin in the southwest and Tangshan and Qinhuangdao in the southeast. A set of thick strata is distributed in this area, which is called Tuchengzi Formation. The footprint fossils of Tuchengzi Formation were first reported in 1992. On April 5, 1992, during their tour in Chengde, ecologist Fuman of Harvard University and Huang Runhua, director of the Department of geography of Peking University, found more than 20 dinosaur and bird footprints on the thick plates on the moving side and southeast side of Rehe spring in Chengde summer resort. Then, more than 40 dinosaur and bird footprints between 6cm and 20cm long were found on the thick plates of the main gate and archway of Xumi Fushou temple. On April 21, 1992, Guo Jianwei and you Hailu of the Institute of Paleovertebrates and Paleoanthropology of the Chinese Academy of Sciences investigated Chengde area, and found a single footprint fossil on the surface of the paving stone slab near Rehe spring. Then, the news of the discovery of dinosaur footprints in the region often appeared in the media. In 2006, Professor Martin & middot lockley of the University of Colorado (Denver) and other scholars described the four bird footprints found on a thick stone slab in the area, which were classified as aquatic bird footprints. However, except for the four bird footprints, the dinosaur footprints in Chengde area are almost blank.
