The earth is 4.6 billion years old. In its long history, there have been many giant creatures that we cannot imagine. Today we will take a look at the 5 most terrifying giant beasts in the world, especially the last one. He is still alive today. In existence! Let's take a look at their true colors.
The first species, Dunkleosteus , lived in the Devonian 405 million years ago. Generally, the small Dunkleosteus is more than 6 meters long, and the large ones can reach about 11 meters. Its head It comes with a pair of hard armor, and its jagged teeth are particularly terrifying. We all know that the bite force of shark teeth is amazing, and can reach 1.2 tons, but no matter how ferocious the shark is, it is always a dish in front of it. The bite force of Dunkleosteus is 5 to 8 times that of sharks.
The second type, Deinosuchus . It is called Deinosuchus because it feeds on dinosaurs. They lurk in the shallows for a long time and hunt lone dinosaurs. Deinosuchus lived in the Cretaceous period and reached a length of 10 to 15 meters. It was an amphibian with a powerful attack power. It was generally difficult for dinosaurs that fell on its mouth to escape.
The third type, Canglong . It lives in the deep sea and is 17 to 25 meters long, which is equivalent to an ordinary train car. It is big but very flexible and can swim 83 meters per minute. The Canglong has a very developed nervous system on its head, which can determine the size and location of the prey in front of it through small changes in the water flow. This skill is beneficial to its hunting. The mouth of Canglong is 1.6 meters wide when fully opened, and its teeth are 15 centimeters high. They are cone-like and slightly tilted inward.

The fifth type is the sawtooth shark. It is 20 meters long and can eat dozens of people in one bite. But in fact, in the long history of biological evolution, sharks have always been a big dish, enjoyed by other giant creatures. Until the emergence of megalodon , it completely changed The fate of the shark family. Its powerful fighting power comes from its huge size, flexible body and keen observation. Among giant creatures, its IQ is the highest. The teeth of the megalodon are 20 cm to 25 cm. An ordinary whale can be bitten in two by it. What is even more terrifying is that the bite force of its teeth is as high as 20 tons, which can kill Tyrannosaurus rex in an instant!
