What are the methods to protect the origin of paleontological fossils?
The protection mode in the primitive natural state is generally suitable for the key protected fossils with low protection level and the general protected fossils. In-situ protection measures include: erecting signs (marks, explanatory boards, warning signs, etc.). ) and pull the net and pull the fence; Reinforce fossil-bearing strata that are easy to collapse due to weathering and denudation; Construction of drainage works for fossil-bearing rock strata that may be damaged by running water. If the fossil sites are relatively concentrated in a range, geological reserves and geological parks can be established. For example, the silicified wood in Yanqing, Beijing, and the fossil rocks in dinosaur footprints are all protected in the original natural state (Figure 5-3).
In-situ site protection refers to the protection of important paleontological fossils exposed on the surface by building protective sites such as greenhouses, exhibition halls and museums in situ, which is mainly suitable for key protected paleontological fossils with high protection level. For example, the origin of dinosaur fossils in Zhucheng, Shandong Province (Figure 5-4) is protected in the form of venues.
