The reason there are so many dinosaur eggs in Heyuan is because many dinosaurs lived there before they became extinct. The source of the river in ancient times was probably a low-lying swamp, and the natural conditions were very suitable for dinosaurs to thrive. Dinosaurs choose Feng Shui treasures to live in. Ancient geography and ancient vegetation hide typhoons in the south and miasma in the north. The paleoclimate, paleoenvironment, and ecological river source are all in the same origin.
According to research and speculation, it is likely that a mudslide temporarily isolated the dinosaur ruins from the air and was preserved. Later, the low-lying land was uplifted due to orogeny, and these ancient ruins were able to be seen again.
