The earth is composed of seventy percent of the ocean and thirty percent of the land, of which the ocean occupies the vast majority, but also the field that human beings have not yet set foot in, since the scientific and technological progress has been a leap forward, human beings gradually out of the earth, see the more vast universe, standing at the highest place, only to know how small human beings are, even the earth is a small one of tens of thousands of planets, in addition to the universe is full of mystery, the ocean is also mysterious. Until now, human understanding of the ocean is only the fur, due to limited technical capabilities, the marine environment is relatively harsh, humans do not dare to bother, some people speculate that there are many habits and fierce creatures in the ocean, not only huge in size, hunting ability is one of the best. Let's look at the marine behemoths that have existed since ancient times.
Ancient marine reptiles. Lived in the late Cretaceous period. It is found in shallow coastal areas and belongs to the suborder Quailidae and the superfamily Plesiosauridae. The family consists of nearly 20 known genera, the largest of which is more than 10 meters long. The body is slender, the head is medium in size, the neck is short and thick, and the tail is equal to the length of the body. The body is snake-like and twisted during movement. The limbs are fin-shaped and play a helmsmanship role. The anterior and posterior feet are multi-toed segments. Up to 10 toe nodes are more. The teeth are tapered, large and sharp. It was a large and ferocious aggressive animal in the water at that time. Fossils of the dragons are mainly produced in North America and Europe, and there are also a small number of records in Asia, and no such fossils have been found in China.
Also known as the toothed whale, an extinct ancient marine mammal, a close relative of modern whales, is a species of cetacean that lived in the late Eocene 39 million to 34 million years ago. The Ryuoo Whale was initially mistaken for a fossil of a giant marine reptile, so it was named the Monarch Lizard. It was first discovered in Louisiana, USA, and paleontologists have since identified at least two other species from fossils found in Egypt and Pakistan. The dragon whale has a maximum length of 18 meters and weighs 20 tons, even up to 21 meters, but it is only suspected to be a dragon whale. And it has a more slender body than modern whales. Paleontologists are intrigued by their degenerate short hindlimbs because it could show that modern whales originally evolved from terrestrial mammals. The Dragon King Whale is also a state fossil in Mississippi and Alabama.
Because sharks are bony fish, it is difficult to leave fossils in general skeletal parts, so as of 2013, only some of its triangular teeth and several spine fossils as large as palms have been found. Adult megalodon teeth are generally 10-16 cm long and longer than 18 cm long, several times the teeth of great white sharks. Although no complete fossils of its upper and lower jaws have been found, scientists have calculated that the shark is about 20 meters, weighs about 90 tons, and has a mouth diameter of 2.8 to 3 meters based on the size of its teeth.
Also known as leviathan melvillei, it lived 13 million years ago. Leviathan Whale is named after her famous American writer Herman Melville, the author of Moby Dick. Melville whale is an extinct toothed whale found in South America during the Miocene. Leviathan whales are named after Herman Melville, the author of Moby Dick and a famous American writer. The huge teeth of Melville whales ( some up to 36 cm long , up to 40 cm ) suggest that the behemoth once preyed on tougher prey, even baleen whales larger than itself.
The FlakeOsaurus was an odd-looking plesiosaur that resembled a dwarf with an extra-long neck. Flakeosaurus used this neck to sneak up on prey from a distance without fear of being spotted by the prey. They quietly bide their time, then snap their necks up like lightning and bite their prey. Although Flakeosaurus was large, their heads were small, making it impossible to attack large prey. Flakeosaurus lived in the water all his life and made a living by fishing. They often go to the bottom of the seabed to search for small pebbles to swallow, which not only helps the stomach grind food, but also adds ballast to swim. Flavonosaurus often traveled long distances in search of mates and breeding grounds, and there is evidence that they would raise their cubs until they could rely on themselves.
Cruosaurus got its name from the Titan of Greek mythology, the ruler of the universe, Kronos. Cruosaurus is one of the largest plesiosaurs in the world , living on the Apudi/Albi order of the early Cretaceous. The type specimen of Queensland Knodonosaurus was discovered in Queensland in 1889, the site was shallow sea at 120 million years ago, and the fossil was narrated by Heber Longman in 1924 and preserved at the Queensland Museum. The second species, Poiacakosaurus, is a relatively intact fossil discovery in 1977 in villa de Leyva, Colombia, and described by Hampe in 1992, where fossils were found.
The Leeds fish, an extinct giant thick-stemmed fishfish that lived between 165 million and 155 million years ago in the middle of the Jurassic Period, is considered the largest teleskeletal fish ever recorded and the largest fish on Earth. The closest thing to a Leeds fish in the living fish is the bowfin fish, but the relationship between the two fish is still far apart. The name of the Leeds fish means "Leeds fish" and is named after the fossil collector Ephraim Nixon Leeds discovered its fossil in Peterborough, England, in 1886. After discovering its fossil, Leeds used prospericus as the species name of the Leeds fish because the fossil was so fragmented that it was difficult to identify and describe it.
Cup vertebrate ichthyosaurs were raptors from the Mesozoic oceans. From the appearance point of view, the cup vertebrate ichthyosaur is relatively primitive, its body is slender, about 10 meters. Their slender shape is very similar to today's dolphins, which can be called the "dolphin" of ichthyosaurs. Consistent with its original identity , the cup vertebrate ichthyosaur did not have a dorsal fin , not a back bulge unlike in later ichthyosaurs , but its up to the tail was flattened like an eel , forming a tail fin. This long tail makes them good swimmers. They also have a typical pair of ichthyosaur teeth and an elongated beak. They often swim in deep waters, waiting for their prey to be delivered to their doors.
6 m long and weighing 2 tonnes, it was a carnivorous marine reptile belonging to the short-necked Plesiosaur suborder Plesiosaurs. Slippery Tooth Dragon lived in the Carof order of the Middle Jurassic, about 170 million years ago to 155 million years ago. " Slippery Toothosaurus " was a marine reptile who , during the late Jurassic period , its stout figure wandered around driven by four medium-sized paddle fins. The long jaws of the slippery toothed dragon are full of sharp teeth. The structure of the nasal cavity of " Slippery Tooth " allowed it to smell in the water , allowing " Slippery Tooth " to spot prey at great distances. In addition to breathing on the surface, the slippery toothed dragon spent its entire life in the water, so they were also oviparous animals, preferring to give birth in shallow waters.
It is a paleontologist that lived in the Devonian era (about 360 million to 415 million years ago), with a body length of about 8 to 10 meters and a weight of up to 4 tons, and its main food is fish and invertebrates with hard shell protection. The main prey was boneless fish and invertebrates protected by hard shells, such as right-angled stones and sharks of the time, which were the top predators in the Earth's oceans at that time. Some people say that due to the fact that the fossils of this fish were found, it was called Dingyu, and later called Dun's fish according to the transliteration. It is considered to be the second largest prehistoric fish in bite force, and it is also the largest fish in the Devonian period, according to the research of archaeologists and zoologists, the Dunn's fish was almost a dominant position on the seabed at that time, and it was a top marine predator.
It lived between 87 million and 65 million years ago, was 6 meters long, and was a natural enemy of sharks such as cretoxyrhina. The sword-shooting fish has a dark blue back and a silvery belly, which serves as a camouflage color for it above and below. The combination of a sharply bladed tooth and a strong tail makes it a formidable chasing hunter.
