Ten prehistoric beasts, each more ferocious than the last

Huge prehistoric creatures once lived on the earth. They were ferocious and terrifying, even bigger and more ferocious than dinosaurs. When I see them, I just want to be glad that they don't live with humans for a century, otherwise they could make humans extinct.

First place: Prehistoric giant fish

This kind of fish is about 360 million years old. From some photos and simulations, we can see that the prehistoric giant fish was a very vicious fish. This kind of fish is usually about 10 meters long, and their weight can reach about 2 tons. In addition, they have very strong jaws and hard teeth, which allow them to dominate the marine ecosystem. Scientists once discovered the fossils of this fish. Through a series of analyzes and measurements, they showed that this fish has the strongest bite force in the history of the earth so far. The scientists also conducted some research on the bite force of this fish. Simulated tests show that their bite force can be as high as 5,000 kilograms. Scientists say this fish is most likely the first king of beasts on Earth.

Second place: Basilosaurus

Basilosaurus, also known as toothed whale, is an extinct ancient marine mammal and a close relative of modern whales. It is a type of whale and lived in the late Eocene epoch 39 to 34 million years ago. Basilosaurus was initially mistaken for the fossil of a giant marine reptile, so it was named the Emperor Lizard. It was first discovered in Louisiana, USA, and paleontologists later identified at least two other species from fossils found in Egypt and Pakistan. The maximum length of the Basilosaurus is 16 to 18 meters, the weight is 8 to 18 tons, and it can even reach 21 meters, but that one is just a suspected Basilosaurus. And it has a slender body than modern whales. Their short, vestigial hindlimbs are of great interest to paleontologists as evidence that modern whales originally evolved from terrestrial mammals. Basilosaurus is also the state fossil of Mississippi and Alabama.

Third Place: Ancient Centipede

Ancient centipedes lived during the Carboniferous period and became extinct during the Permian period 300 million years ago. The body length can reach 8.6 feet (approximately 2.59 meters) and the appearance is similar to a modern centipede. It looks very scary and is huge. Fortunately, this animal lived more than 300 million years ago and will never pop up around anyone now. Ancient centipedes may have lived during the Carboniferous period and became extinct during the Permian period 300 million years ago.

Fourth place: Anomalocaris

Anomalocaris, also known as the weird shrimp, is an ancient creature found in Cambrian sedimentary rocks in China, the United States, Canada, Poland and Australia. It is the largest known Cambrian animal. According to speculation, such animals are most likely to be active carnivores. In the ocean 530 million years ago, the most ferocious predator was Anomalocaris. It has a pair of giant eyes with handles, a pair of giant segmented forelimbs for catching prey quickly, a beautiful large tail fan and a pair of long tail forks. Although it is not good at walking, it can swim quickly. The huge mouth with a diameter of 25 cm can prey on any large creature at that time. The mouth has external teeth arranged in a ring, which poses a major threat to animals protected by mineralized outer armor. This is a carnivore with strong attack power. Its maximum size can reach more than 2 meters, while most other animals at that time only averaged a few millimeters to several centimeters. Anomalocaris, which can reach a maximum length of 2 meters, is considered to be the earliest apex predator in the Phanerozoic marine ecosystem and one of the most representative star animals of the "Cambrian Explosion".

Fifth place: Devil Frog

Devil frog, prehistoric devil frog is also called devil toad. The era of survival was the middle to late Cretaceous period about 70 million years ago. At the beginning of the 21st century, European scientists excavated a 40.6 cm long fossil of this frog. The scientists estimated that the anal snout would have been 43-45 cm when it was alive. When stretched out, the total length is more than 1 meter. It weighs about 9 to 10 pounds or more. This frog lived 65 million to 70 million years ago; it was the largest frog in history and was so ferocious that it could even eat newborn dinosaurs. The "Devil Frog" is 41 centimeters long and weighs an estimated 4.5 kilograms. It has a strong build, a wide mouth and powerful jaws.

Sixth place: Chalk spiny shark

During the Late Cretaceous, the spiny shark was the largest shark in the ocean and one of the most formidable predators. Nicknamed the "golden kitchen shark", it can use its mouth full of sharp teeth like kitchen knives to cut its prey into thin slices or small pieces. There is also evidence that the spiny shark can also hunt mosasaurs, plesiosaurs, and even swordfish, which are vicious carnivorous fish themselves. The spiny shark's teeth can never be lost, which is consistent with its living habits. It not only eats meat, but also eats the bones together. And if there is food that cannot be digested, the spiny shark will directly expel it from the body by vomiting. The chalk spiny shark can grow more than 10,000 teeth in its lifetime.

Seventh place: Pteranodon

Pteranodon is a pterosaur from the late Cretaceous period, a flying reptile, while dinosaurs are land animals. Pteranodon was about the size of a turkey, weighing about 15 kilograms, but its length was about 1.8 meters and its wings spread about 8.2 meters. The head was huge, the beak was very long, there was a skin pouch on the throat and neck, and the mouth was completely toothless. It might have used its big mouth to swallow fish like today's pelicans. Perhaps in order to balance the head, there is a large bony crown extending backward on the top of the head. This kind of pterosaur cannot flap its wings for long periods of time and has to rely on high-altitude air currents to glide across the ocean. When resting, it may hang upside down on a branch with its hind limbs like a bat, or it may fold its wings and use its limbs to crawl short distances on the ground.

Eighth place: Titanoboa

Titanoboa is an extinct species of anaconda and is the largest known species of snake. They looked like enlarged versions of modern pythons. Titanoboa can reach an average length of 12 meters and weigh more than 1 ton. These two figures are enough to illustrate their terrifying nature. Their food included the 4.57-meter-long, half-ton blunt-nosed crocodile and the 3.05-meter lungfish as well as some large contemporary turtles. Titanoboa became extinct nearly 58 million years ago. It was the largest terrestrial carnivore on earth after the extinction of the dinosaurs. It dominated the earth for millions of years. Titanoboa may be more than 15 meters long, weigh more than 1,100 kilograms, and the thickest part of its body is more than 1 meter.

Ninth place: Mosasaurus

Mosasaurs were the largest apex predators in the Mesozoic oceans. The adult body length of Hoffmann's Mosasaurus can reach 15 meters. It is recognized as the largest individual with a body length of up to 17 meters. There is a big difference in weight according to different reconstructions. The two more mainstream versions are: "lizard type" about 13-16 meters. tons, and its thickness is similar to that of the Komodo dragon, which is also a data commonly used in China. The stout version is about 17-24 tons, which is the weight calculated based on the newer restoration. Although mosasaurs have a short history (evolved from cliff lizards on land, appeared and multiplied rapidly in the middle and late Cretaceous, and then became extinct together with the dinosaurs), they have been riding the wind and waves all the way, largely because of the above Niche vacancies caused by the extinction of dragons and ichthyosaurs.

Tenth place: Emperor Crocodile

Crocodylus crocodile, also known as crocodile crocodile, king crocodile and super crocodile, means "muscle crocodile" and is an extinct crocodile. They lived in Africa during the Early Cretaceous and were one of the largest crocodile animals that ever lived. Emperor Crocodile is 8-13 meters long and weighs 4-11 tons. It feeds on various prehistoric fishes as its main food. Not only that, the crocodile's sense of smell is extremely sensitive, and it can smell the smell of prey even in the water. Coupled with its 1.8-meter-long mouth full of sharp teeth, even a small dinosaur can become its prey in an instant. Things in the mouth.
