Recently, the "Cretaceous Research" magazine published online the latest research results of the Xu Xing-Jin Changzhu Yanji project team of the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences
The Yanji fossil site was identified in 2016 by Jin Changzhu, a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences.
After discussing with various experts, Jin Changzhu discovered that this was actually a dinosaur skeleton, and in 2016 led a number of experts back to the Sun River to investigate
Due to the fact that there are relatively few terrestrial strata in the world during this period, Yanji will become a very important site for the world to study the vertebrate fauna of the mid-Cretaceous
After continuous field work in recent years, a large number of vertebrate fossils have been discovered in Yanji, including dinosaurs, crocodiles, turtles and turtles
Compared with other Mesozoic biota, the domestic research on Mesozoic crocodile type is still slightly insufficient.
In the past few decades, a lot of morphological and taxonomic work has been on the fossils of southern crocodiles living in the crocodile type of Gondwana, and the new crocodile has received much less attention, but this one But it has a lot to do with the origin of modern crocodiles
According to the latest research, Longshan Yanji crocodile belongs to the new crocodile
The research was supported by the National Natural Science Foundation of China, the Jilin Yanji Dinosaur Culture Research and Development Center, and the Canadian Museum of Natural History
