Abstract:
In 2016, abundant dinosaurian, crocodiliform and testudine fossils were recovered in the southern part of Longshan and western part of the Sun River in Yanji, Jilin Province. Five fossil-bearing layers have been discovered in Longshan locality, with a total thickness of about 10.6 m. The third and fifth fossil-bearing layers are stable and continuous, while the other three layers are discontinuous, with limited distribution in the deposits. Based on the comparative paleontological and radiometric dating data, it is inferred that the age of the Longshan fossil stratum is 100—91 Ma age, and thus the fossil-bearing beds were formed in the earliest Late Cretaceous.
