Haimi, today's long talk about the ocean, let's take a look at some of the more powerful prehistoric sea monsters.
1
Megalodon
Megalodon sharks with blood basins and invincible bites are the best song of the ancient family of sharks, ranking first on the sea monster list.
At the beginning of the 19th century, many huge fossil teeth were discovered. In 1843, paleontologist Agassis named megalodons based on these huge fossil teeth. The megalodon is the most destructive sea monster ever built, with a body length of more than 15 meters and a weight of about 40 tons. Megalodon sharks are like enlarged great white sharks, with more than 250 teeth in their large mouths 3.4 meters wide and 2.7 meters high, any of which is the size of a human palm. Megalodon sharks have a bite force of 20 tons, which is equivalent to the strength of 5 tyrannosaurs combined. For megalodon sharks, the average small fish and shrimp are simply not enough to plug the teeth, and only thick cetaceans can satisfy their appetites. However, as cetaceans grew larger and migrated to colder seas for food, megalodons living in warmer seas disappeared because they lost the food they depended on.

Dunn's Fish
With its hard armor and sharp teeth, the Dunn's fish is the peak of primitive fish evolution, ranking second on the list of sea monsters.
In the Devonian oceans, The Dunn's fish were invincible, and they ate almost anything. Dunn's fish hunting also has a weapon - a powerful suction, its large mouth that opens in an instant can suck food into the mouth at once, and then the bite-strong teeth come in handy. As evolving fish swim faster and faster, Dunn's fish begin to face a food crisis, and they can't catch up with their prey. As a result, this Devonian sea monster gradually became extinct.

Canglong
With a good sense of smell, rows of teeth and powerful explosive power, the dragon is the pinnacle of sea reptile evolution, ranking third on the sea monster rankings.
In the Mesozoic oceans, the Dragon is the ultimate sea monster, and in addition to being threatened by sharks and other dragon species in its infancy, it no longer has predators in adulthood. Fish, turtles, marine crocodiles, plesiosaurs and even pterosaurs and other species of dipterosaurs are on their diets. If it were not for the mass extinction at the end of the Mesozoic Era, the dragon would have ruled the oceans for much longer.

Dragon King Whale
With good hearing and strong cutting power, the Dragon King Whale kicked off the dominance of mammals over the ocean, ranking fourth on the sea monster rankings.
At the beginning of the 19th century, many strange fossils were found in the central United States, and it was believed that these fossils belonged to some kind of dinosaur. In 1834, the scholar Harlan named the Dragon King Whale, which originally meant "Lizard King Dragon", and later learned that they were a cetacean. The Dragon King Whale is the nouveau riche in the Cenozoic ocean, with a body length of about 20 meters and a weight of about 18 tons, making it the slenderest whale in the body. Slender Dragon King whales swim like eels, not very fast, but very agile. The killing tool of the Dragon King Whale is the teeth in the mouth, and its teeth can be pierced or cut.
In the Eocene oceans, the Dragon King Whale was the absolute king, and no animal could shake their hegemony. The Draco whales had a lot of food, and they not only ate fish, but also hunted other small cetaceans of the same era. In the late Eocene, the Earth's climate began to become cold, and the Dragon King Whale could not adapt and was extinct.

On the dragon
With sharp eyesight and long pointed teeth, the Dragon is an outstanding representative of reptile conquest of the ocean, ranking fifth on the list of sea monsters.
The Upper Dragon was one of the first paleontology to be discovered, and its massive fossils were found in what is now the southern part of England. The famous paleontologist Owen named this large marine reptile in 1841. The Dragon was a reptile in the Jurassic Ocean, breathing through its lungs, reaching a length of up to 15 meters and weighing more than 10 tons. The dragon's large head is more than 2 meters, and a large flat mouth and a mouth full of fangs are their killing tools. Behind the big head is a short and thick neck and a huge body, providing a powerful bite force and power for the dragon.
In the Jurassic ocean, the upper dragon was a huge and fierce predator, and the only ones who could compete with it were slippery toothed dragons and flat-nosed strong dragons. In addition to eating various fish, they also ate ichthyosaurs, plesiosaurs and even dinosaurs.

nautilus
With its long pointed hard shell, flexible tentacles and beak, the Nautilus kicked off the era of sea monsters, ranking sixth on the list of sea monsters.
A long time ago, many pointed stone awls were found in the rocks. At first, people didn't know what it was. It was not until modern times that paleontologists confirmed that these stone awls were the shells of the ancient Nautilus. In 1933, paleontologist Techter named the animal. The Ordovician nautilus was one of the first giant predators in earth's history. They are more than 10 meters long, longer than a bus. The Nautilus has a peculiar shape, resembling a straight-shelled conch that can swim. Interestingly, because they spray water from their heads, they move forward upside down. Don't look at the nautiluses funny, but they are terrible hunters, their hard mouths resemble the beaks of the parrot's mouth, with a strong bite force.
