The lizard king dragon is a large theropod carnivorous dinosaur that lived in the late Jurassic period, belonging to the family Alitrosauridae. It was one of the largest carnivorous dinosaurs of the Jurassic period, second only to the North American Tan's Barbarian in size and slightly smaller than the Portuguese format Barbarian. Fossils were found in the latest layer of the Morrison Formation in New Mexico and Oklahoma, USA, indicating that they appeared very late in the area or were relatively rare in number. Huge size. The legs were thicker and longer than those of the allosaurus, indicating that it was much larger in height and weight than the allosaurus. In addition, the base of the dorsal nerve spine of the lizard dragon has a vertical lamina, which is their most prominent feature.

Mamenchixiosaurus, one of the largest sauropod dinosaurs found in China, lived about 0.16 billion years ago in the Late Jurassic. It is famous for its long neck, which can reach 12.1 meters in length, accounting for almost half of its body length. The head is relatively small, the teeth are thin and stick-shaped, suitable for gnawing high plants. The limbs are strong and strong, the forelimbs are short, the hind limbs are long, and the tail is long and strong, which helps to maintain the balance of the body. Living mainly in plains with lush plants and abundant water, they spend most of their time in lakes and marshes, floating their bulky bodies with the help of water. Foods on young leaves of tall trees and low shrubs.

One of the largest sauropod dinosaurs ever discovered in China, Mamenchixiosaurus lived during the Late Jurassic period, about 0.155 billion to 0.16 billion years ago. It is found in Mamen Creek, Yibin, Sichuan, China. The most notable feature is the extremely long neck, accounting for half of the body length, with up to 19 cervical vertebrae, the longest neck of all dinosaurs. The head is small, the teeth are thin and stick-shaped, suitable for nibbling leaves. It mainly lives in plains with luxuriant plants and abundant water, and feeds on the twigs and leaves of tall trees and low shrubs. Most of the time spent in lakes, swamps, with the help of water floating bulky body. The tail is long and strong and can be used to support the body

Stegosaurus is a large herbivorous dinosaur that lived in the late Jurassic period and belongs to the family Swordosaurus. The body length can reach 7-9 meters, the height is 2.35 to 3.5 meters, and the weight is about 2 to 4 tons. The most notable feature is a row of huge triangular bone plates on the back, which may be used to regulate body temperature, display or defense. The tail ends with four long spines for defense against predators. With a small head and relatively small brain volume, it is considered a less intelligent dinosaur. It walks on four legs and feeds mainly on low plants. Found mainly in North America and Asia, it is one of the most famous dinosaurs of the Jurassic period.

It is a small theropod dinosaur known for its unique jaw and slender hind limbs. The mandible does not have an external mandibular window, and the neural spines of the posterior dorsal vertebrae are fan-shaped and have hook shaped protrusions for attaching ligaments. The first metacarpal bone is short and thick, the cervical spine is retroverted, and the femur lacks the fourth trochanter. Phylogenetic analysis shows that Megalosaurus belongs to the Coelurosauria class, which is a type of theropod dinosaur. In addition, stomach fossils of Megalosaurus suggest that it may have fed on small lizards. The estimated running speed is about 17.8 meters per second. Although the relationship between Megalosaurus and birds is relatively distant, its research provides important insights into the theory that birds originated from theropod dinosaurs

It is a dinosaur that lived in the late Jurassic period and belongs to the suborder Sauropod. Renowned for its enormous size and long neck, it was one of the largest land animals that ever existed on Earth. The skeletal structure suggests that they may be semi aquatic animals, living partially in water, which helps support their weight and reduce energy expenditure during exercise. The head is relatively small, with a long tail and strong limbs, with the forelimbs slightly longer than the hind limbs. Teeth have adapted to feed on plants, possibly relying on low vegetation as their main diet. Although the fossil record of Euphorbia is relatively limited, their existence provides us with important clues about ancient ecosystems.

The stegosaur is an animal belonging to the family Stegosauridae in the suborder Stegosauria of the order Ornithischia, also known as the Bone Plate Dragon. The head is small, and the tip of the mouth has a bird like pointed beak without teeth. The teeth are distributed on both sides of the mouth and are very small. Strong and robust in appearance, weighing up to 4 tons, with 5 toes on the front legs and 3 toes on the back legs; The front legs of the stegosaur are slightly shorter, while the hind legs are longer and more robust. Jianlong is named after its large sword board and sharp tail spikes on its tail. Living in the late Jurassic to early Cretaceous period. The diet is herbivorous. Due to their small teeth, they cannot grind plants and can only eat some low moss or fern plants.

Lianglong is a dinosaur belonging to the family Lianglong in the order Saurischia. The neck is long, the head is small, and the position of the nostrils is higher than the eyes; The front of the mouth has flat teeth, while the sides and back have no teeth; Strong limbs, short forelimbs, long hind limbs; The buttocks are higher than the front shoulders; Each palm has 5 fingers (toes); The tail is longer than the neck and gradually narrows towards the end, forming a whip like shape, with over 10 human bones in the middle. The name Shuanglianglong comes from two protrusions that protrude from the top of the human character bone, resembling double beams, and is commonly referred to as Lianglong. Living in western North America during the late Jurassic period. Living in groups, when there is a shortage of local food, they collectively migrate to distant places. Plant eating, feeding on leaves and ferns.

Camarasaurus is an extinct sauropod dinosaur. It is the most common large sauropod dinosaur in North America, with an adult body size of about 20 meters long and a weight of 15-50 tons. Compared to other long necked dinosaurs, its neck is much shorter and its tail is also shorter, making its physique appear more robust and sturdy. It is one of the most famous dinosaurs in North America. The Latin meaning of its name is a dome shaped reptile. They belong to vegetarian dinosaurs and lived in the late Jurassic period, dating back 155 to 145 million years ago. Compared to other tall relatives in the sauropod family, the dome dragon appears relatively short.

Pterodactylus, a pterosaur of the late Jurassic period, is characterized by a lightweight and compact skull composed of thin, hollow bones. Its first finger is particularly elongated to support membrane wings, and its hind limbs are short. All members of the Pterodactylidae family have short tails and long heads. Some species of pterosaurs have a body size similar to sparrows; Others can be as big as eagles, with wings extending up to 30-70 centimeters, feeding on insects, and some may forage for fish. The entire group of pterosaurs is a suborder of pterosaurs. In terms of classification, it does not truly belong to dinosaurs, but is only a close relative of dinosaurs.

Allosaurus is one of the most famous large carnivorous dinosaurs, occupying the top of the food chain in late Jurassic terrestrial ecosystems. Its model species, the fragile Allosaurus, was created by the great American paleontologist Osnil in the 20th century Marsh described the naming in 1877. They are also the most abundant and widely distributed predators discovered in the Late Jurassic period. Adult Allosaurus can grow up to 9 meters in length, with a few individuals believed to reach up to 12 meters. Although not as robust as the Tyrannosaurus rex, the body proportions of the Allosaurus are more symmetrical, with more developed forelimbs, making it appear more agile. The number of specimens is also much larger than that of Tyrannosaurus rex.

Archaeopteryx is a dinosaur belonging to the family Archaeopteryx in the order Saurischia. The size is similar to that of medium-sized birds today. Flexible head, slender neck, short body, long and stiff tail; The arms, forelimbs, and long tail are covered with feathers, while the thumb faces backwards; It has sharp teeth, claws on its wings, sharp and curved claws at the end of its hind toe, and a bony coccyx. Living in the late Jurassic period, mostly distributed in southern Germany. Carnivorous animals feed on insects and fish. Not strong in flying ability, only suitable for short distance flight; Unable to live in trees for a long time, but skilled at running on the ground. Scientists believe that it may be the first terrestrial organism to transform into a bird.
