In the early Cretaceous, large theropods-like E Long, Nepal and Africa-all found their fossils, like E Long, which was 12 meters long and burly.

The forelimbs have huge claws as long as 30cm, and the head is very similar to that of crocodiles, hence the name E Long. Their forelimbs are strong and their hands have three fingers.

There is a big sickle-shaped finger claw on the thumb. It seems that E Long's mouth is slender, which is very suitable for catching fish. But for large herbivores,

Dinosaurs pose less threat.

Huayanglong:

Huayanglong, a middle Jurassic stegosaurus, was first discovered in Zigong, Sichuan, China, and was named to commemorate the ancient Huayang country where fossils originated. Huayanglong is 4 meters long and weighs 1 to 4 tons. On its back, from the neck to the tail, there are also two rows of symmetrical sword boards, and the front and rear legs are almost the same length. Huayanglong has four sharp spikes on its tail, which is its secret defense weapon.

Blackhead:

In the late Cretaceous, Percy Cartron was first discovered in Montana, USA. Pacicantosaurus was 5 meters long. The main feature that distinguishes it from other dinosaurs is the abnormal swelling and thickening of the bones above the head. Paleontologists speculate that male pachycephalopods often have head-to-head collisions, and the winner can maintain a high social status in the population.

Triceratops:

Triceratops is a large ceratosaurus in the late Cretaceous, which was first discovered in Denver, USA. Triceratops is 9 meters long. Their most striking feature is that their big head is the largest of all land animals, and they have a bony neck shield like a shield. According to some data, Triceratops can run at a speed of 30 kilometers per hour. At the end of Cretaceous, Triceratops were numerous and lived under the same blue sky as Tyrannosaurus Rex. As you can imagine, they have had countless encounters with Tyrannosaurus Rex.

Megalodon:

Megalodon is a large theropod dinosaur in the middle Jurassic, and it is the first megalodon fossil found in a quarry in Oxfordshire, England. Megalodon is a huge and terrible carnivorous dinosaur with a length of 10 meter and a weight of 3 tons. Megalodon's big mouth is covered with big, sharp teeth, and its roots are deeply embedded in the lower jaw, so the biting force is very strong that even the most intense biting struggle will not loosen the teeth.

Spiny Ankylosaurus:

In the early Cretaceous, Ankylosaurus was a dinosaur. The earliest place where Spinosaurus was discovered was the Isle of Wight in England. Ankylosaurus is 6 meters long and has a small head. It feeds on ferns and is very strong. Ankylosaurus has a soft abdomen. When invaded by carnivorous dinosaurs, Ankylosaurus will crawl on the ground and its abdomen will be well protected. The bone spur sticking out of his body made the enemy flinch.

Frost wyrm:

Ice Chironosaurus is a medium-sized theropod dinosaur in the early Jurassic, which was first discovered in Antarctica and the only theropod dinosaur fossil found in Antarctica. Frost wyrm is a cold-blooded crested reptile, bipedal and carnivorous, 6 meters long and weighing 2 tons. Because of the dense vegetation and warm climate during the Jurassic period, Antarctica is a paradise for frost wyrm. Frost wyrm is rich in colors. It has a crown on its head with dense blood vessels and nerves. Once congested, the color will be brighter.

General Si Shan Ling Long:

In the Late Jurassic, a medium-sized theropod dinosaur, the single-ridged dragon of Jiangjunmiao, was first discovered near Jiangjunmiao in Junggar Basin, Xinjiang, China. The single-ridged dragon in Jiangjun Temple is 6 meters long, with big head and sharp teeth. Its hind limbs are 1.5 times as heavy and powerful as its forelimbs, and its forelimbs also have sharp claws. The prominent feather crest on the head of the single-ridged dragon in Jiangjun Temple is its greatest feature. They are also divided into single-ridged dragons and double-ridged dragons, which is probably a sign of mutual recognition between the same species.

Lumbricus:

Early Jurassic stegosaurus fossils were first discovered in Dida Village, Lufeng, Yunnan, China. The length of the big earthworm is about 1.5 meters. This big earthworm is about the size of a big goat. His skull is very low and long, and his back is covered with a small deck. According to the research of scientists, earthworm may be the earliest stegosaurus. Big earthworms have small fangs in front of their mouths, which can easily bite off twigs on branches and usually walk on all fours in dense forests.

One-horned dragon:

In the late Cretaceous, Ceratosaurus one-horned dinosaur fossils were first discovered in Montana and Canada. One-horned dragon, about 6 meters long, was an early Ankylosaurus with a medium posture. Their bodies are similar to those of modern rhinos. They have these four short legs, a heavy body and a thick tail. One-horned dragon also has a parrot-like mouth, feeds on ferns and cycads, and has a huge neck shield extending backwards above its head.

Godzilla:

Godzillon, a late Triassic theropod dinosaur fossil, was first discovered in Mexico, USA. Godzilla, 5 meters long, is a large coelenterate and should be regarded as one of the earlier dinosaurs. The biggest feature of Godzilla is that it is light, can move quickly and has strong viability.

Kamakura era:

The fossil of Kamakura era is a large theropod dinosaur, which was first discovered in Mongolia in the late Cretaceous. The body length of Kamakura is 1 1 m. Kamakura has a very strange appearance. His head is small, his stomach is fat, he moves slowly, his feet are wide and short, and he may be covered with primitive feathers. His mouth is stiff, because there is a support called bone stick on his coccyx, which is a world of four unlike dinosaurs.

Mamenhiro:

Mamenxilong, a giant sauropod dinosaur in Jurassic and Cretaceous, was first discovered in Hechuan, Sichuan, China. Mamenxilong is 35 meters long and weighs 30 tons. Mamenxilong's neck rib is the longest among all dinosaurs, reaching 2. 1 meter. In the whole body structure, the length of the neck accounts for half, ranking first among all terrestrial creatures throughout the ages. Mamenxilong is the most famous long-necked dinosaur.

Li Li Enlong:

In the Late Triassic, a medium-sized theropod dinosaur, Lilian Dragon, its fossils were found in France and Germany. This dragon is 4 meters long. It has a long neck and a long tail. Its hind legs are strong, but its forelimbs are unusually short. It belongs to early large carnivorous dinosaurs. Li Li Enlong's recipes are very rich, but when food is extremely scarce, he will also attack the early large dinosaurs together.

Nanxionglong:

Nanxiong dinosaur fossil is a medium-sized theropod dinosaur in the late Cretaceous, which was first discovered in Nanxiong, China. Nanxiong dragon is 4 meters long and has three pairs of sickle-shaped claws, belonging to Kamakura. The feeding habits of Nanxiong dragon have always been a mystery. Some people think it feeds on ants like anteaters, others think it is an expert in fishing, and others think it is a vegetarian at all.

Gas dragon:

In the Middle Jurassic, a small theropod dinosaur, Qilong, was first discovered in Dashanpu, Zigong, Sichuan, China. Riding a dragon is 4 meters long and 2 meters high. Its main characteristics are big head, short neck, long tail, short and flexible forelimbs and strong hind limbs. Chirosaurus was an active and agile dinosaur in the Middle Jurassic. It can be said that riding a dragon was good at running and was a terrible hunter in the dinosaur fauna at that time.

Qingdao Dragon with Sharp Mouth:

In the late Cretaceous, a large hadrosaur (pungent Qingdao Dragon) was first discovered in Laiyang City, Shandong Province, China. Qingdao dragon with pointed nose is 15 meters long and has a pointed nose dragon crown on its head, hence the name. Tsingtao sauropod is the most famous crested duck-billed dragon in China. The best preserved Qingdao Dragon fossil with the highest fossil content in China is kept in China Dinosaur Museum.

Sheng Wang Long:

In the late Cretaceous, a large theropod dinosaur was superior to Wang Long, and its fossil was first discovered in Narmada River area of India in 1986. St. Wang Long's body length can reach 10 meter. He is heavy and strong, with short forelimbs and strong hind legs. He usually walks on his hind legs. Wang Shenglong also has a horn on his head, but its horn is particularly short and round, just like an ornament worn by an ancient king on his forehead, showing the elegance of a generation of kings.

Tyrannosaurus rex:

In the early Cretaceous, Tyrannosaurus Rex, a medium-sized theropod dinosaur, was first discovered in the Isle of Wight, England. Tyrannosaurus rex is 4.5 meters long, and its slender forelimbs and hind legs support its body. The first Tyrannosaurus rex was the earliest ancestor of Tyrannosaurus rex, which filled the blank of Tyrannosaurus rex pedigree. Tyrannosaurus Rex was the most successful dinosaur in the middle and late Cretaceous. Fossil evidence shows that Tyrannosaurus rex evolved from a relatively primitive stone bone, and its origin can be traced back to Jurassic.

Spinosaurus:

Spinosaurus dinosaur is a giant theropod dinosaur in the late Cretaceous, which was first discovered in Baiharier Oasis in Egypt. Spinosaurus is 17 meters long, with long spines on its back, round teeth and a mouth like a crocodile. According to the data, the attack ability and predation ability of Spinosaurus are similar to those of Tyrannosaurus Rex, and it is a very strange carnivorous dinosaur. Fish and pterosaurs may be its recipes. The biggest feature of Spinosaurus is the long spines on its back, and there are skin connections between the long spines to form sails.

Dragon:

In the late Cretaceous, a large ceratosaurus, Euphorbia, was first discovered in Montana and Canada. This dragon is 6 meters long and is a medium-sized ceratosaurus. Its cervical spine is strong, its limbs are strong, and its toes curl outward. The dragon is characterized by a circle of sword-like spines on the edge of the neck shield, which is like a sword, enough to make fierce predators tremble.

Brachiosaurus:

Brachiosaurus was a giant sauropod dinosaur in the late Jurassic, which was found in Colorado, Utah, Portugal and Tanzania. Brachiosaurus was 28 meters long and weighed 88 tons. Like other giant herbivorous dinosaurs, brachiosaurus had a long neck and a small head, and the mound above it was its nose. Brachiosaurus's nostrils were all on the top of his head. Brachiosaurus's forelimbs are higher than its hind limbs, which is very beneficial to support its long neck. When brachiosaurus raised its head, it was as high as 12 meters above the ground, and it could easily feed on the young leaves of tall plants.

Multicolored crested dragon:

In the late Jurassic, a small theropod dinosaur, Coloured Guanlong, was first discovered in Xinjiang, China. The colorful crested dragon is 3 meters long, with forelimbs like wings and feathers like birds and dragons! This is strong evidence that birds and dinosaurs originated from the same ancestor. The multicolored crown of dinosaurs is large and fragile, full of air, and it is the most exquisite crown of any dinosaur except birds. These are decorations used to attract partners or show off their status.

Yongchuanlong:

Yongchuan District, Chongqing, China, the first discovery of the late Jurassic large theropod dinosaur Yongchuan Dragon. Yongchuan Longchang 1 1 m, standing 4 meters high. Yongchuanlong has a big three-corner head about 1 m long, with six pairs of big holes on both sides, which effectively reduces the weight of the head and enhances the flexibility. Yongchuanlong, as a large carnivorous dinosaur, often haunts jungles and lakes.
