1. Huge reserves. There are more than 200 individuals, including dinosaurs, fish, amphibians, turtles, plesiosaurs and crocodiles. Among them, dinosaur species include protosauropods, sauropods, theropods, ornithopods and stegosaurus, accounting for 1/2 of the total in Sichuan and 1/6 of the total in China. It is the largest dinosaur cave in China, and only the National Dinosaur Memorial Hall in Utah and the Dinosaur Provincial Park in Alberta are equally famous in the world.
2. There are many kinds. The fossils here are not a single or monotonous vertebrate fossil group, but a complete vertebrate group consisting of at least 5 classes, 1 1 order, 16 families and more than 40 genera and species from fish, amphibians and reptiles to mammals. * * * There are 47 species of vertebrate paleontology, belonging to 36 genera, of which 26 species belong to 2 1 genus. It covers almost all dinosaur species in the early, middle and late Jurassic.
3. The remains are very spectacular. The fossil burial hall in the museum is one of the largest fossil burial places in the world, with the highest fossil enrichment level in the world. At the same time, the site still retains a relatively complete geological profile, which has its special geological significance. This paleontological fossil site has been included in the pre-selection list of UNESCO World Geological Sites, and it is one of the "first-class" sites recommended by the World Heritage Committee's World Heritage List.
4. High integrity. The dinosaur and other vertebrate fossils in the collection are highly intact, and most of them are intact skeletons preserved together. Among the more than 200 individuals that have been excavated, there are more than 40 bones with integrity rate over 60%, and there are more than 10 bones with integrity rate over 80%. This is very rare in vertebrate paleontology and has important value. 5. Boutique collection. In addition to well-preserved dinosaurs, there are rare trace fossils such as dinosaur skins, dinosaur eggs, dinosaur footprints, dinosaur tail hammers, and many fossils of animals and plants contemporary with dinosaurs, such as pterosaurs, plesiosaurs, crocodiles, fish, turtles, spiny willows and ginkgo biloba. Many of them are world-class treasures with important scientific value, and they are a colorful "Jurassic animal treasure house".
6. Special value. The Middle Jurassic dinosaur fossils owned by the museum are of great significance in the evolutionary history of dinosaurs. Before the discovery of Dashanpu dinosaur fauna, early and middle Jurassic dinosaur fossils were only found sporadically in North Africa, East Asia, Western Europe and Australia, which made the dinosaur evolution series not well connected and there was a "blind spot". The discovery of Dashanpu, a rich middle Jurassic dinosaur fossil group, just fills the gap in the evolutionary history of dinosaurs, and has important scientific value for studying the systematic evolution, physiological characteristics and living environment of dinosaurs and related ancient animals. It has been praised by academic circles as "the greatest harvest in the history of dinosaur fossil excavation and research in the world in the past two or three decades" and "the hall of Jurassic dinosaur research in the world".
7. Beautiful scenery. The main building of the dinosaur museum has a unique shape, just like a huge pile of stones standing on the ground where dinosaur fossils are produced. The visitor center is like a huge stegosaurus lying across the vast and quaint subtropical jungle, and the two complement each other. There are a large number of Mesozoic plants in the park, such as Cycas, Ginkgo biloba and conifers. In particular, more than 30 kinds of plants known as "living fossils" were transplanted, which fully created the prehistoric environment in which dinosaurs lived. The whole park has a beautiful environment and pleasant scenery, which is a good place for tourism and leisure. summary
The Jurassic paleontological fossil resources in Zigong Dinosaur Museum are extremely rich, and there are many fossil remains. In particular, it is famous for its rich dinosaur fossils, various types, concentrated burial and well-preserved. This is the world-famous Jurassic "hometown of dinosaurs". Fossil species are extremely rich. From fish, amphibians and reptiles to mammals and mammals, it is a complete vertebrate fauna composed of more than 40 genera of at least 5 classes 1 1 orders 16 families, covering almost all terrestrial vertebrates in Jurassic, with systematic and complete biological evolution.
Sauropods
Sauropod dinosaur is a familiar dinosaur. All sauropods are roughly similar. Their huge bodies are supported by four thick legs. They walk on all fours, with long necks but small heads. Spoon-shaped or rod-shaped teeth are only suitable for eating tender plants.
Theropod suborder
Theropod dinosaurs are a very prosperous group in the dinosaur family. Their fossils have been found from the Middle Triassic to the whole Cretaceous, and they are also widely distributed. as a whole
In fact, theropod dinosaurs had different heads, generally longer faces, stronger hind limbs than forelimbs, and walked on two feet.
Niaojiao
The ornithopod dinosaur is the earliest branch of ornithopod dinosaur and the backbone of its evolution. Other ornithopods, such as Stegosaurus, Ankylosaurus and Ceratosaurus, all evolved from ornithopods. Bird-footed dinosaurs appeared in the Middle Triassic, propagated to the end of Cretaceous, and lived on the earth for more than 100 million years.
stegosaurus
Stegosaurus, also known as Bone Dragon, is generally not very big, with a body length of 3 ~ 9 meters, walking on all fours, living in the jungle near rivers and lakes and feeding on plant branches and leaves; Its biggest feature is that there are two rows of triangular or polygonal bone spur plates with different sizes along the back of the bow, and there are two pairs of slender bone spurs at the tail tip, which is named because of its peculiar clothing.
Associated animal
There are many kinds of companion animals in the dinosaur era, including fish, amphibians, turtles, crocodiles, plesiosaurs, pterosaurs and mammal-like reptiles.
Dinosaur skull
Among the skeleton fossils of vertebrates (especially large vertebrates), skull fossils, especially complete skull fossils, are the most rare. However, 10 complete skull fossils of dinosaurs and other vertebrates were unearthed in Zigong area, which is of great scientific significance to the study of Jurassic dinosaur fauna in Zigong area.
Skeletal fossils
Among Zigong dinosaur fossils, there are two kinds of special bone fossils unique to the world, namely sauropod dinosaur tail hammer and stegosaurus shoulder spine, which provide reliable fossil basis for studying the physical function and behavior of these two dinosaurs.
Trace fossil
Among dinosaur fossils, skeleton fossils are the most common, but trace fossils such as dinosaur skin fossils, footprint fossils, egg fossils and feces fossils are rare, which is of great significance for studying dinosaur body structure, physiological characteristics and behavior patterns.
