The strongest carnivorous dinosaurs in the world are (11 species): Diplodocus, Utahraptor, Beef-eating Dragon, Allosaurus, Megalodon, Squatooth Dragon, Yongchuan Dragon, Southern Megalodon, Mapulong, Spinosaurus and Tyrannosaurus Rex.

11. Diplodocus

Body length: 4 ~ 7m

Weight: 4kg ~ 5kg

Life period: Early Jurassic

Habitat environment: canyons and waters

Main food: sauropod dinosaurs, lizards and other small animals

Fossil discovery: China and the United States < It is a pity that this kind of crown is "beautiful and useless" and can only be used as an ornament. In addition to the big crown, the mouth of Diplodocus is also very special-sharp and narrow, and the maxilla can move. Therefore, Diplodocus can take out small animals hiding in bushes or cracks in stones and eat them. For Diplodocus, any meat is tempting, and they can be said to have no meat and no joy. Therefore, they are never picky about meat, whether it is the internal organs of animals, the remains of animals, or carrion, they must eat it first. Diplodocus lived earlier. Compared with other carnivorous dinosaurs, Diplodocus is very "skinny". Because of this, they usually run very fast. Double-ridged dragon's hind legs are powerful, and it moves quickly and quickly, which are essential for hunting. Animals in the early Jurassic, as long as they are targeted by him, almost no one can escape their sharp teeth and sharp mouths. In recent years, some fossils of Diplodocus have also been discovered when people visited Antarctica. This shows that Antarctica, which is now covered with ice and snow and extremely cold, was once a dinosaur paradise with a warm climate during the Jurassic period.

1. Utahraptor

Body length: about 7m

Weight: about 5kg

Life period: early Cretaceous

Habitat environment: plains and woodlands

Main food: meat

Fossil discovery: U.S.

Utahraptor's' skeleton recovery map'. They have a high IQ, and they not only react quickly, but also make judgments on things within one second. And the body is flexible, jumping ability is very strong, you can make a sudden turn or jump in mid-air to chase prey. No wonder people regard them as dangerous terrorists. Utahraptor likes group activities. Taking advantage of the strength of dragons, they often shuttle through vast plains and dense forests and launch sudden attacks on animals bigger than themselves. Utahraptor has a very outstanding talent for fast running. Their body length is about 7 meters, but their weight is only about 5 kilograms; Their strong hind legs and big feet are very powerful fast running tools. In this big family of carnivorous dinosaurs, they are rare runners. Utahraptor is related to Velociraptor, but it is much bigger than him, and it belongs to the big man of Chirosaurus. If he runs, the top speed can exceed 5 kilometers per hour. They have sharp hooked claws on the second finger of their hind legs. With these claws, they can easily tear the flesh of their prey. The earliest Chilong dinosaurs appeared in the middle of Jurassic. This kind of dinosaur has lived on the earth for at least 1 million years. Scientists concluded that they had the closest relationship with Utahraptor.

9. Beef-eating sauropod

Body length: 7 ~ 9m

Weight: 1.35t ~ 2.5t

Life period: Late Cretaceous

Habitat environment: woodland, near lakes

Main food: meat

Fossil discovery: Argentina

Niu Long (imagination). Although only one fossil from Niu Long has been found so far, it is completely intact, except for the tail and some leg bones. Niu Long is the largest dinosaur with the fastest running speed known. It is said that its speed can reach 6 kilometers per hour, which can be said to be a cheetah in the Cretaceous period.

Niu Long's skin and fossil Niu Long's huge head, strong bite mouth and razor-sharp teeth all show their lethality as top predators. When hunting, they are used to repeatedly biting the neck of their prey with their teeth until the other side is dying, and then they will slowly enjoy a good meal. So far, only one incomplete Niu Long fossil has been found. On the back and sides of this fossil specimen, the researchers found many small bumps, which are very similar to those on the crocodile skin. This indicates that Niu Long's skin may not be smooth. The horn on the bull's head is not a weapon, but a tool to deter the enemy. Compared with other carnivores, Niu Long's eyes are slightly forward, which is very rare among dinosaurs.

8. Allosaurus

Body length: 8~12m

Weight: 2t~5t

Life period: Late Jurassic

Habitat environment: plain

Main food: meat

Fossil discovery: North America

Allosaurus (pictured), also known as Yuelong or Allosaurus. Allosaurus is a medium-sized bipedal predatory dinosaur. Allosaurus was a brutal predator active in the late Jurassic. At that time, they were huge, fierce and tyrannical, killing prey everywhere. At that time, almost no dinosaur didn't fall under their teeth. At that time, in the North American continent, Allosaurus, which dominated the world, had almost no rivals. Allosaurus had a big, long mouth. Their powerful jaws are full of sharp teeth, which can easily pierce the flesh of their prey. Moreover, Allosaurus' teeth are changing rapidly, and the cycle of losing teeth and growing teeth has been going on.

The predation pattern of Allosaurus, the head fossil of Allosaurus, will change with age. When they were young, they were strong and quick, and often tried their best to hunt down escaped prey. After a certain age, their bodies seem to become heavy, and their actions begin to be clumsy and slow. At this stage, Allosaurus will take the initiative to change its predation strategy, instead of blindly pursuing prey, it will hide behind the scenes and wait for a good opportunity to pounce slowly. When visiting the skeleton model or restoration model of Allosaurus in the museum, you may find a pair of small horns on the head of Allosaurus. In fact, this pair of small horns is the weak horn crown of Allosaurus, which is composed of tear bones extending upward. Paleontologists infer that there is probably keratin on the horn crown, and different horn crowns have different functions. For example, some Allosaurus used it to block the sun. Others use it to attract the opposite sex ...

7. Megalodon

Body length: about 9m

Weight: 5kg ~ 1t

Life period: middle Jurassic to early Cretaceous

Habitat environment: woodland

Main food: meat

Fossil discovery. They are tall and have big, sharp teeth. This dinosaur first lived in Europe in the middle Jurassic, and then gradually moved to Africa, Asia and other places. Megalodon has a large skull, and its upper and lower jaws are covered with fangs, and it has a strong bite force. Bite prey is generally difficult to break free. When hunting, Megalodon will rush at its prey, and then bite its neck crazily, until the other party falls down and enjoys a good meal. Each tooth of Megalodon was about 1 cm long and serrated. They are arranged in a zigzag way, just like handfuls of daggers inserted backwards. Megalodon can grow new teeth in a short time after shedding its old teeth.

The shape of Megalodon Many dinosaur footprint fossils have been found in Cambridge, England. Researchers believe that these footprints may belong to Megalodon. People also inferred the running speed of Megalodon according to the size of footprints and the distance between footprints-they could run about 3 kilometers per hour, that is, 5 meters per minute. People discovered the fossils of dinosaurs a long time ago, but they were always mistaken for the fossils of monsters or other animals. It was not until 1824 that a British geologist, buckland, named these fossils as Megalodon. The earliest scientifically described and named member of the dinosaur family is Megalodon, which means "giant lizard in the quarry" in Latin.

6. sauropod

length: 12 ~ 14m

weight: 6t ~ 11.5t

life period: late Cretaceous

habitat: plains, forests

main food: meat

Fossil discovery: Africa

sauropod (from dinosaur planet). They were once brilliant, occupying the throne at the top of the land food chain for millions of years. However, the powerful ones finally disappeared in the fierce and cruel competition. So their thrones had to be handed over to the rapidly rising dinosaurs such as Tyrannosaurus Rex, Abercrombie Dragon and Spinosaurus. The tooth shape of the shark-toothed dragon is named after the tooth shape of a modern shark. As can be seen from the fossil, this tooth is like a curved dagger, which is thin and sharp, and has very obvious lines.

As a representative of large carnivorous dinosaurs in Cretaceous, the teeth and head fossils of the sauropod have a huge body size that matches its identity. According to the fossils that have been found so far, the body length of the adult shark-toothed dragon is generally 12 ~ 13 meters, and the limit body length can reach 14 meters. What is this concept? That is to say, it is equivalent to the length of the bus we usually take. Tall and strong, he was unmatched on the African continent and was one of the most powerful predators there at that time. Most theropod dinosaurs were fierce predators, and Sharodon was no exception. In the hungry period, the shark-toothed dragon will take the lead in attacking each other when hunting, knocking down or stunning each other with its strong body, and then raising its hind legs when the prey is too late to react, and ending each other's life with the last bite. After that, they bent down and bowed their heads, opened their mouths and gnawed with sharp teeth. When the prey died of excessive blood loss or lost the strength to resist, the shark tooth dragon would enjoy the food happily.

5. Yongchuanlong

Body length: 7 ~ 11m

Weight: 4t

Life period: Late Jurassic

Habitat environment: jungle, lakeside

Main food: meat

Fossil discovery: Sichuan, Chongqing, China

Forever. In 1977, when the upstream reservoir was built in Yongchuan area of Chongqing, a dinosaur fossil was dug up. Therefore, the research team named the fossil specimen upstream Yongchuan Dragon. Yongchuan Dragon was strong and weighed about four tons, which was enough to dominate China at that time. They are used to being alone, hot-tempered, and like to do something. Even in normal times when they are not hungry, they often "bully" other animals and enjoy the fun of causing trouble. The eyes on both sides of Yongchuan dragon's skull are relatively close. In this way, external objects will partially overlap visually and become more stereoscopic. Therefore, Yongchuanlong can quickly and accurately judge the position of prey, and then launch a storm on prey to capture prey. Yongchuanlong is a large carnivorous dinosaur. They are about ten meters long and can be four meters tall when standing, so their skulls are very big and have six pairs of "holes", which can effectively reduce the weight of skulls. In addition to a pair of eye holes, the other five pairs of these six pairs of large holes connect the muscle groups on the cheek, which may enhance the occlusal ability of Yongchuan Dragon.

4. southern behemoth

length: 11 ~ 13.5 m

weight: 6t ~ 1t

life period: middle and late Cretaceous

habitat: swamp, forest

main food: meat

fossil discovery: Argentina

. The southern behemoth is a large carnivorous dinosaur. Compared with other dinosaurs, its head is larger, its chin is square, and its jaws have a sharp tooth, which is like a shark's tooth like other dinosaurs in the same family. Compared with other dinosaurs of the family Squaodontidae, their heads accounted for a larger and longer proportion of their bodies, but their forelimbs were shorter, and their biting ability and biting speed were higher. Second only to Tyrannosaurus rex as we know it on land. They are also the largest carnivorous dinosaurs and one of the most powerful predators.

Orthomorphic skull of the southern behemoth

Compared with the skull of the Argentinean dragon, the skull of the southern behemoth is relatively low as a whole, and the dentition length of its maxilla is about 92 cm. The maxilla has a well-developed inferior nasal process and a small oval maxillary hole. The back of the nasal bone is very rough and full of wrinkles. This rough surface extends to the back of the skull and covers the whole back of the nasal bone. The lacrimal bone forms a very developed ridge at the intersection of the anterior process and the inferior process, which is similar to many Allosaurus. The joint between the suborbital process of the southern behemoth and the zygomatic bone has a protrusion that goes deep into the orbit. The square bone is about 44 cm long, and its interior has a cavitating structure. The frontal bone and parietal bone are wide, which blocks the superior temporal fossa to a certain extent. The odontoid bone is longitudinally raised at the odontoid joint. Each tooth bone may have 12 tooth sockets. Except for the first tooth, the mandibular teeth are all similar in size. Teeth are thin, with serrations at both the leading edge and the trailing edge, and the density of serrations is about 9-12 serrations per millimeter. There are obvious enamel folds on the surface of teeth. Biomechanical research found that the bite force of southern behemoth was weaker than that of Tyrannosaurus rex. Therefore, paleontologists believe that the big mouth of the southern behemoth is more suitable for tearing the flesh of its prey, rather than crushing the bones of its prey directly like Tyrannosaurus Rex. The southern behemoth probably fed on the titanosaurs of its time. The southern behemoth has a very strong neck with a thick axis. The other cervical vertebrae have short and slightly flat vertebral bodies, and there are obvious cavitations in the vertebral bodies. The vertebral body of the coccyx is thick, and the vascular arch of the anterior coccyx is blade-shaped. The shoulder strap bone is short, and the length of the scapula is less than half the length of the femur. The scapular stalk has a strong muscle attachment point. The northern edge of the intestine is arched upward, the posterior process of acetabular fossa is low, and the attachment ridge of coccyx brevis is narrow. The process of the distal pubic bone is well developed, and the anterior edge is shorter than the posterior edge. The femur is S-shaped. The femoral head is very strong, pointing to the medial upper side. The small rotor is wing-shaped, and its proximal end is located under the big rotor. The fourth rotor is developed and points backward.

3. Mapulong

Body length: 1.5 ~ 14m

Weight: 4t ~ 1t

Life period: Late Cretaceous

Habitat environment: forest and plain

Main food: meat

Fossil discovery: Argentina

The research shows that Mapulong and Megasaurus are related and very similar. The adult Mapulong can reach 12 meters in length, while the ultimate length of Rose Mapulong can reach 14 meters. The weight can generally reach five tons, and the heaviest recorded can be 12.5 tons, which is similar to the southern behemoth. The fossils of Mapuron are composed of scientists from Argentina and Canada.
