[music] The earth formed about 4. 5 billion years ago. And over time they have been developing numerous forms of life.
Several species disappeared. Others have continued to evolve and are still part of our ecosystem today. Among all the animals that inhabited planet earth throughout its existence are the dinosaurs.
We know of its existence thanks to the many fossils that were found. It is well known that there were dinosaurs of all types and sizes. The largest that was the size of a building.
To the little ones who would be the size of a rabbit. In this video we will focus on the dinosaurs that stood out for being true kings of their time. Authentic nature hunters.
Able to brutally destroy your enemies. Be it for your speed, size, intelligence or brute force. See now.
The most dangerous prehistoric dinosaurs. Ankylosaurus His name means armored lizard. It lived during the Cretaceous period in the locality that is now North America.
Average height 1,70 m. 6. 25 m in length.
It weighed 6 tons. It had a body totally protected by armor. And it had a huge mass on its tail.
Which he used to use to confront his enemies. In the end it was a quiet animal, which used its formidable defenses to deter its enemies. Allosaurus The Alosaurus lived at the end of the Jurassic period where the United States and Portugal are currently.
With an average of 9 meters in length and 3. 5 meters in height. They weighed about 2,200 kilograms.
Same as an Indian rhinoceros. His head was light. But his jaws had 70 spear-shaped teeth.
They had to face gigantic dinosaurs. They probably used a method of ambush to hunt and attack their prey in group. Pentaceratops This dinosaur lived in North America.
It was 8 meters long and 4 meters high and weighed 5,500 kilograms. His appearance was incredible to the other dinosaurs. He had three horns on his head, a strong beak and thorns on his tail.
He walked in packs. And all his attacks served to intimidate his enemies or decide who was the leader of the group. Because he was a herbivore, he used his beak to pluck the plants off the ground.
Carnotauro This dinosaur lived at the end of the Cretaceous period in what is now South America. It was 9 meters long and weighed more than a ton. His appearance was scary.
Because he had two horns on top of his head. Paleontologists determined that he had a formidable sense of smell. That ran at high speed.
And that his skin had crocodile-like scales. It turned out that he used the horns against members of his own kind. And that he had small eyes so he would not be hurt while fighting.
Velociraptor You should know the speed of this animal thanks to the movie in the movies. But the film has some inaccuracies. In the first part of the saga, paleontologists find the dinosaur skeleton in the Montana desert.
What is impossible. Because this animal lived in the desert of Asia. His appearance also distorts reality.
The dinosaur had a feathered body, especially on the forearms. Your name means fast thief. And it was feared by the other dinosaurs.
He had 28 teeth per jaw. And a claw in the back legs he used to nail to the victims. At the time of the attack, he leaned over a limb.
And he kicked the other to get on his prey. Utahraptor This relative of the velociraptor was worse than he. He lived in the town that is now the state of Utah.
It was relatively small. It was 7 meters long. And it weighed 600 pounds.
It had an incredible claw, 24 inches long. Scientists discovered that just like his relative, he was covered in feathers. But do not be fooled.
He was a dangerous animal. Tyrannosaurus rex The most famous of all prehistoric dinosaurs. Its name means: king lizard.
He lived in the locality that is now North America. It measured 12 meters long with 4 meters high. It weighed 6 to 8 tons.
The head was five feet. It had teeth that were 19 centimeters long and could reach up to 30 centimeters in length. Turning him into the dinosaur with the best teeth.
His teeth could exert pressure on his prey from 3 to 5 tons. Force enough to tear the flesh and break the bones. On the other hand, paleontologists do not know what their actual velocity was.
But it probably reached 54 kilometers per hour. Carcharodontosauro This dinosaur lived in the locality that is now Africa. Its name means, sharp tooth reptile.
It measured 13 meters in length and weighed 15 tons. It had a head 1,6 meters long. His great teeth destroyed the enemies.
And the hook-shaped front claws served to suspend anything. Besides, he was extremely fast. Able to run at a speed of 9 meters per second.
Giganotosaurus This predator dinosaur lived in the locality that is now Argentina. It was 12 meters high and weighed 8 tons. His head was 1,5 meters long.
He was so big that he ate animals the size of a Tyrannosaurus. Her front legs had three large clawed toes. Despite this, he had a weakness.
His size prevented him from running. Paleontologists confirmed this when they found their femur. More likely they were predators of ambushes.
Spinosaurus If you watched the movie, you will remember the dinosaur. It was the largest carnivore among all known dinosaurs. It measured 12.
5 meters in length and weighed 20 tons. He had a long, narrow head. And over his eyes they had small crests.
They had large spinal extensions in the vertebrae of his back. The largest can reach 2 meters in length. There is a whole discussion about its usefulness.
He spent so much time in the water; as on earth. It was similar to a current crocodile. Their main prey were the dinosaurs that fed on fish in the rivers.
These were the most dangerous dinosaurs in prehistory. After watching this video, you may be thinking of being a paleontologist. But remember, you can end up in the desert.
Or in some other place not pleasant.
