This is a very interesting place, there is a ** experience area, life three defenses, these are closely related to our lives. There is also the mysterious Geological Museum.
Experience the artistic crystallization of nature's ingenuity. Of all these projects, the one I remember the most is the ancient fossils. Over billions of years on Earth, a lot has happened.
Among them, there is one thing that has always surrounded us, and that is - the extinction of dinosaurs. In the mysterious geological museum, we saw dinosaur fossils, there are large dinosaurs, small dinosaurs, dinosaurs on land, dinosaurs in the ocean, dinosaurs flying in the blue sky, ......The most surprising thing for us was that there were two huge dinosaur fossils, and there were five meters tall that no one of them was taller. Looking at the two huge dinosaur fossils with their heads held high, I can't help but think that hundreds of millions of years ago, these two dinosaurs may have been the king of dinosaurs.
After hundreds of millions of years of ups and downs, there are only a few complete dinosaur fossils, which has put a veil of mystery on modern human research!

Several ancient algae fossils dating back about 1 billion years were accidentally discovered by primary school students who went to the Mentougou Mountains. Experts preliminarily speculate that these fossils are 1 billion years old.
The primary school students who went to the Kunying Valley Resort in Wangping Town, Mentougou District to hold summer camp activities unexpectedly found some stones paved on the scenic road, printed with many patterns that looked like plants. Later, after the preliminary identification of experts, the children found "dolomitic limestone", which is an ancient algae fossil, which is 1 billion years old. The largest of these algae fossils is about 1 meter long, about meters wide and about meters thick, and there may be multiple layers of fossil structures inside.
