How many kinds of dragons are there in the world? What is the information about Longlong?

It is biologically classified as a superfamily. The biggest difference between dinosaurs and other reptiles lies in the posture of standing and the way of marching. Dinosaurs are completely upright, with their limbs directly under their bodies. This structure has more advantages than other reptiles (such as crocodiles, whose limbs extend outward) when walking and running. According to the different structural characteristics of dinosaur belts, they can be divided into two categories: sauropods and ornithosaurs. The main difference between them lies in the belt structure: the belt of sauropods is shot from the side, the pubic bone extends forward under the intestinal bone, and the ischium extends backward, similar to lizards; Very ugly. The waistband of ornithischia expands greatly in the front and back of the intestinal bone, and there is a large pubic protrusion on the front side of the pubic bone, which extends below the intestinal bone, and the back side extends parallel to the ischium to the front and bottom of the intestinal bone. So the pelvis is radiant from the side (there are other differences). Sauropods are divided into sauropods and theropods. Sauropods are divided into protosauropods and sauropods. Protosauropods mainly lived in the Late Triassic to the Early Jurassic, and were omnivorous medium-sized dinosaurs, such as Ban Long, the first giant dinosaur living on the earth, and Ankylosaurus living in the Early Jurassic. Sauropods mainly live in Jurassic and Cretaceous. Most of them were giant vegetarian dinosaurs. Small head, long neck, long tail and small teeth in spoon shape. The famous representative of sauropod is Mamenxilong, which was produced in Sichuan and Gansu provinces of China in the late Jurassic. It consists of 19 cervical vertebrae and is the largest known animal in the world-Zhenlong or fragile double-chambered dragon. Theropod dinosaurs lived from the Late Triassic to the Cretaceous. They are all carnivorous dragons, walking on two feet, with sharp claws on their toes and well-developed heads, and they are the smartest one. There are teeth as sharp as daggers or knives in the mouth. Tyrannosaurus rex is a famous representative, and the others, such as Allosaurus and the southern behemoth, are also famous. The suborder ornithopoda can be divided into five categories: ornithopoda, stegosaurus, Ankylosaurus, Ceratosaurus and pachycephala. Ornithopoda is a group with the most fossils in ornithopoda and even the whole dinosaur category. Tadinosaur

Children walk on two or four feet. The mandible has a single anterior tooth bone, and the teeth only grow on the cheeks. The crowns of the maxillary teeth bend inward, and the crowns of the mandibular teeth bend outward. They lived from Late Triassic to Cretaceous, and they were all vegetarian dinosaurs. Such as: hadrosaurs, Iguanodons, etc. Stegosaurus was a quadruped with an upright bone plate on its back and two or more pairs of bony spines on its tail. It mainly lived from Jurassic to early Cretaceous, and was the first large extinct dinosaur group. Its representatives are Stegosaurus and Kenterosaurus. The former is thought to live in the plain, while the latter is found in Tanzania. Ankylosaurus dinosaurs were short and stout, covered with bone decks, and ate plants, mainly living in the early Cretaceous. For example, Hailaerlong lived in continental Europe, Ankylosaurus lived in Britain, Baotou Dragon lived in the United States and Edmonton Dragon lived in Mongolia. Ceratosaurus is a four-legged vegetarian dinosaur. The back of the skull expanded into a cervical shield, most of which lived in the late Cretaceous. The parrot-billed dragon found in northern China belongs to the ancestor type of Ceratosaurus. Among them are Triceratops, the docile herbivorous dinosaur protoceratops and so on. The main characteristics of pachycephalosaurus are that the skull is swollen and thick, the hole is closed, and the pubic bone in the pelvis is rejected by the ischium and does not participate in the formation of the band. It mainly lived in Cretaceous. Whether sauropods or birds, their belts leave a small hole between the intestine, ischium and pubis, which other reptiles do not have. It is this hole that shows that these two animals, called dinosaurs, are the closest relatives compared with all other reptiles.
