Everyone knows that there are many animals in the world, and they have always maintained the entire ecological balance. played a very important role, but you may not know that before the birth of human beings, there were several tenacious and terrifying animals on the earth, even scientists banned their resurrection If they have been alive, the human world does not know what kind of disaster it will face, so today I will share with you the animals that have been banned from resurrection in history,
1. Giant rats
The guinea pig, as we know it, is a smart and cute little rodent. However, 8 million years ago, you would never consider bringing them home as pets, and guinea pigs at that time weighed 680 kilograms and were up to 1.5 meters tall, so you can imagine that an animal about the size of a buffalo would be scared when standing up. And when he stands on all fours, the total length is about 4.5 meters, and he is a herbivore, with incisors about 20 centimeters long. But giant rats don't take the initiative to find food, they usually lurk in the grass, waiting for their prey to appear, and once the prey passes in front of them, it is impossible to escape from under their minions. But it also has natural enemies. That is the prehistoric giant crocodile, it is understood that the largest size of the prehistoric giant crocodile can even grow up to 9 meters, they are the only threat to the prehistoric giant rat, and fortunately, the prehistoric giant rat eventually became extinct for unknown reasons, otherwise, it is no joke that humans want to deal with 1.5-meter-old mice.
2. Dun's fish
This armored prehistoric fish does not belong to the shark family, but is a late devonian shieldfish. It existed at the end of the Devonian period, about 380 million years ago, when Dun's fish was one of the predators at the top of the food chain. This armored fish does not have a single tooth bottom. But in order to eat, its snout has a head armor that can crush anything, and its main prey is hard-shelled fish and invertebrates. It can grow up to 10 meters long, and its bite force is so strong that it can even bite metal, enough to easily and neatly cut off a human arm.
3. Spin-toothed shark
This is another ancient marine animal with bizarre teeth that swam in the deep ocean 20.9 billion years ago. At about 10 meters long, the spinodont looks like a shark but is twice the size of a great white shark. The spiral tooth shark also has a nickname - the spiral saw killer, because the teeth of its lower jaw are similar to the spiral serrations, but the upper jaw has no teeth. Its spiral teeth consist of an arrangement of 15 to 18 serrated teeth that bite like a helical saw when it chews its prey. The scary thing about it lies in its overly sensitive sense of smell and rather strong teeth. Although the spin-toothed shark is a very mysterious marine animal, intelligent humans have also discovered the horror of the spin-toothed shark according to various signs, their sense of smell is very sensitive in the water, even if only a trace of blood is exposed, the spin-toothed shark can chase the bleeding creature far away, and with its sharp teeth will be reduced to food in its mouth.
4. Dire crocodile
This prehistoric crocodile was an opportunistic predator at the top of the food chain and lived about 82 million years ago at the end of the Cretaceous period. It belongs to the family Crocodylidae and can grow up to 11.9 meters long. This huge short-tailed crocodile likes to inhabit estuaries and feed on turtles and even dinosaurs, which can eat dinosaurs as big as it. Evidence suggests that dinosaurs have a powerful jaw that can crush turtle shells and brute force to repel other predators. It would adopt a hunting pattern similar to that of today's crocodiles, immersing its body in water and attacking dinosaurs or other terrestrial animals close to the shore until the prey drowned. The dinosaur may be the top predator in the region, and if the dinosaur lived now, it would be scary enough to think about.
5. Great ape
It is an extinct ape that lived in the Pleistocene between 2.69 million and 11,700 years ago. The great ape may be like a transitional panda, and you may be frightened by his size, which stands up to 3m tall and weighs up to 500kg. The morphological characteristics of giant apes are between apes and humans, giant apes have strong canine teeth and huge white teeth, the size of teeth is about 5 times larger than modern human teeth, biting off a bowl-thick bamboo is as easy as breaking a toothpick. Because it is too large, the place where the great ape walks will bring a lot of movement, however, because the fossils found are incomplete, it is difficult to simulate the real appearance of the great ape.
6. Giant piranhas
This dangerous fish is 70 cm long and weighs about 13.6 kg. Living in the Miocene 10 million years ago, not only was it three times larger than the modern black piranha, but the bite caused by this prehistoric fish can also be said to be a horror legend. The bite force can be as high as 484 kg, which is about 50 times its body weight. He can easily bite through the shell of a turtle, or the scales of an armored catfish. Piranha is a terrifying creature in ancient life, frightening, piranhas are mainly distributed in his Mason River It is said that piranhas are very ferocious, it only takes 5 minutes to eat a cow, and the giant piranha eats people only takes 1 minute Very terrifying piranha bloodthirsty, smell blood will immediately call accomplices, they have a very keen sense of hearing, have effective encirclement tactics. In the water, they first bite the lethal part of their prey, like a well-trained warrior, a sharp bite immediately gives way to their accomplices, and groups take turns fighting, and in only ten minutes, animals as large as cows are eaten clean.
