Dinosaurs, as a behemoth that once lived on the earth for hundreds of millions of years, disappeared in ancient times because of the mass extinction, but scientists have never stopped studying dinosaurs. What are the 5 super terrifying dinosaurs that have existed on Earth that are now known?
Type 1: Wounded Toothed Dragon
Wounded Toothosaurus is considered to be the most intelligent dinosaur, because its brain tissue is the largest of all dinosaurs, scientists believe that the IQ of Wounded Toothosaurus should be the most developed among dinosaurs.
The large mouth of the wounded tooth dragon had a terrible pile of sharp teeth, and if the open mouth was covered with sharp nails, it was very frightening, and the wounded tooth dragon existed in the late Cretaceous period about 65 million years or 75 million years ago. Living in the Late Cretaceous Period, they would bury the eggs of the dinosaurs they gave birth to in the sand and then incubate the eggs themselves. It can be compared to the ostrich.
For example, kangaroos have an IQ of 0.7, while the IQ of the wounded tooth dragon is as high as 5.3, and paleozoologists have had a bold idea that if there was no disaster in ancient times and the dinosaurs did not go extinct, they would most likely evolve into "dinosaur people" who replaced humans and became the masters of the earth.
Species 2: Giant Beast Dragon
Also known as the Southern Megalopodosaurus, they were carnivorous dinosaurs second only to Tyrannosaurus rex in size, with a maximum body length of 13 meters and a maximum energy of 11 tons. Living in South America between 100 million and 92 million years ago in the Cretaceous Period, the megalopoda also had a strong bite force, and once the prey was bitten by the 9-13 cm long fangs of the megalopod, it was difficult to escape.
As far as the head of the southern giant beast dragon is estimated to be the largest among the carnivorous dinosaurs, even 30 centimeters longer than the 1.5-meter head of the Tyrannosaurus rex, the head of the southern giant beast dragon is about 1.8 meters long, but it has a thin and long tail, and when the two legs walk and run, the slender tail constantly swings to help maintain balance.
Species 3: Allosaurus
Allosaurus is about 155 million years ago to 135 million years ago in the late Jurassic predatory carnivorous dinosaurs, Ittosaurus belongs to the medium size of dinosaurs, most of them are 8.5 meters long, the largest 9.7 meters, weigh 1.5 to 3 tons, the heaviest 3.6 tons, Allosaurus toes with sharp claws, can easily scratch prey and tear them apart, so the lethality is very good.
Although Allosaurus is a carnivorous dinosaur, which is relatively small, they will fight in groups, besiege and capture other grass-eating dinosaurs, as their own food, and it is also a very fierce existence.
Species 4: Tyrannosaurus rex
Speaking of the name Tyrannosaurus rex, it is probably the most famous dinosaur in the dinosaur family. No matter who knows the word dinosaur, they have basically heard of the famous Tyrannosaurus rex. This is partly because T. rex was the most lethal of all carnivorous dinosaurs. The other is also because the Tyrannosaurus Rex is indeed brave and good at war, and its reputation is outstanding.
Scientists have learned from the complete T. rex fossils found that the fossil is a 28-year-old Tyrannosaurus rex who died of death, and his body is covered with numerous scars.
There were also holes in the bones, and many deep wounds with visible bones were finally healed.
It can be seen that when the Tyrannosaurus rex hunts other prey, it is also in many dangers, and their lives are also in the jungle fight, leaving them to die and reborn.
Tyrannosaurus rex can reach a maximum length of 14 meters, weigh up to 10 tons, and reach a maximum hip height of 5.2 meters. Tyrannosaurus rex had stout and powerful hind limbs that could support it to run fast to chase prey, and it could reach a bite force of 10 tons, the first of all carnivorous dinosaurs.
Fifth: Utah Thief
Utahosaurus, who lived in the early Cretaceous period, was the largest dinosaur in the family Chironidae. It has a peculiar appearance, with two thick long legs and a pair of wings.
Utahosaurus had a wide field of vision, eyes that were good enough to compare with eagles, and was as responsive as a bird of prey, making Utahosaurus the most peculiar of the dinosaurs, generally 7 meters long, 2 meters tall, and weighing up to 600 kilograms. It has sharp claws and is about 28 cm long.
Unlike the Aeolian Pterodactyl, which can fly in the sky, Utah Thief Dragon weighs up to half a ton, and the pair of wings are certainly not moving to fly high, but it can form a state of near-gliding when running fast, faster than the speed of running, which greatly increases the hunting ability of Utah Thief, and also makes their lethality become greater, which in turn increases the threat to other prey.
Sixth species: Diplodocus
Diplodocus is a dinosaur living in the early Jurassic, it is about 6 meters long, weighs half a ton, height is about 2.4 meters, is also a very brutal and ferocious carnivorous dinosaur, its top of the head with two pieces of bone crown, juxtaposed on the top of the head, so it got the name of Bispindrosaurus, its crown can not be used as a weapon, on the contrary, it is more fragile.
This can not take the action of hitting the head when attacking the prey, and the diplodocus also relies on its short but sharp forelimbs and claws to tear the prey, running fast with its relatively thick hind limbs to chase, and using its sensitive sense of smell to catch the hidden lizards and other small animals from the cracks in the stone as a snack for hunger.
For these terrible animals that once existed on the earth, although they annihilated the long river of history, the study of extinct dinosaurs has far-reaching significance for us to have a deeper understanding of the evolution of earth's organisms, but suddenly we are also glad that these 5 kinds of dinosaurs are extinct, otherwise where should human beings go? When encountering these dinosaurs in the wild, can humans still escape the "dragon's mouth"? Or will it be tamed by humans and turned into mounts?
