Introduction to the Geological Science Plaza: The square takes the time of the development of life on earth as the main line. From north to south, it is divided into four parts: Archaean Era, Archaic Era, Phanerozoic Era and Modern Era. The Phanerozoic Era is divided into Paleozoic Era, Mesozoic Era and There are three areas of the Cenozoic Era. In the modern area, the square has a geological park theme monument, and the ground is paved with reliefs of dinosaur skeletons and fossils. It is based on the Triassic Period when dinosaurs first appeared, the prosperous Jurassic Period, and the Cretaceous Period when they became extinct. The boundary forms a square atmosphere with great archaeological significance.
