Introduction To Dinosaur Fossils

Dinosaur fossils refer to the soft tissues of the dinosaur's body that disappeared due to decay after death, and the hard tissues such as bones (including teeth) were deposited in the sand, in an oxygen-isolated environment, after tens of millions or even hundreds of millions of years of deposition. function, the bones are completely mineralized and preserved. In addition, relics from when dinosaurs lived, such as footprints, can sometimes be fossilized and preserved. Zigong is famous for its wide range of dinosaur fossil burial sites, huge quantities, numerous species, well-preserved, and continuous sequences. Zigong Dinosaur Museum is a large-scale site-type natural museum built on the "Dashanpu Dinosaur Fossil Group Site".
The fossilization process began when the dinosaurs died and were quickly covered by sediment or underwater silt. These sediments contain fine particles that form a soft covering on the body. This "blanket" protects the carcass from scavengers, blocks oxygen, and inhibits microbial decomposition.
