The sea monsters we often talk about are widely used in myths and stories or various rumors, and in ancient times, giant marine creatures were also called sea monsters.
Sea monsters are sometimes referred to as small dragons (also known as bass fish), which are carnivorous marine fish, often using suction cups to adsorb the bottom of the boat or other large fish to swim and feed. Feeds on other fish and invertebrates.
The host of the bass varies greatly, and whales, sharks, turtles, sunfish, and even small boats can be boarding stock or following divers. Feed on the remnants of large fish, ectoparasites, or catch invertebrates from shallow seas on their own.
Today we talk about the 10 largest prehistoric sea monsters.
1. Dunn's fish
The Dunn's fish, which existed in the Paleozoic Devonian period (about 360 million to 430 million years ago), is a large paleontology, about 11 meters long, and weighs 6 tons, which shows its size. The Dunn's fish is regarded as the largest predator of the ocean during the Devonian period, and it is also the largest carnivorous teleost fish that appeared during the Cambrian to Devonian period, and its main prey is fish and invertebrates with hard shell protection, which is the top predatory animal of the time.
The Dunn's fish, also known as the dinosaur fish, is now extinct, and its fossils are distributed in Morocco, Africa, Poland, Belgium, and the United States.
2. Slippery Tooth Dragon
" Apatosaurus " was a carnivorous marine reptile that existed between the middle and late Jurassic periods , 160 million to 155 million years ago. As a marine reptile, in the late Jurassic period, its stout figure wandered around under the drive of four medium-sized paddle fins, and it was brutal by nature.
It was a medium-sized marine creature that weighed about 2.5 tons and had a maximum body length of 6.6 meters. The toothed dragon was named in 1873.
Also known as Smooth Lateral Toothosaurus, fossils have been found in France, Russia, the United Kingdom, and Germany.
3. Megalodon
Megalodon, probably the most powerful creature ever discovered in Earth's history, has more bite power than T. rex in its mouth. It existed from the Late Oligocene 15 million years ago to the Early Pleistocene 2.6 million years ago, and was the top predator of the oceans during that period, and it has been called the most powerful creature in the history of Earth by many paleontologists. Megalodons grow about 17 meters and weigh 70 tons, because sharks are cartilaginous fish, and it is difficult to leave fossils in general bone parts.
Megalodon means "big tooth" in Greek, and another nickname is called the big tooth shark, and its fossils are distributed all over the world.
4. Giant stingray
The giant freshwater stingray is one of the largest freshwater fish in the world, a fish that lived millions of years ago and did not expect to exist in this world today.
American biologist Zab Hogan caught a giant stingray up to 4.27 meters in Cambodia's Mekong River, and according to the measurements, this big guy is the world's largest known freshwater fish.
5. Chloron
Cruosaurus was a marine reptile belonging to the suborder Plesiosaurs, and was distinguished by its short, thick neck. Cruosaurus got its name from the Titan of Greek mythology, the ruler of the universe, Kronos.
Cruosaurus lived 120 million years ago (early Cretaceous) and was a plesiosaur with a short neck (pictured). The neck bone has only 12 pieces and the body length is 9-10 meters. Its mouth is almost as long as its head!
Also known as Knoxosaurus, Knosaurus, is one of the largest dragons in the world.
6. Rhine-Yerkers
The Rhinejeckel is the largest plate-footed horseshoe crab ever built (a species that was born at the beginning of the earth's conception, fish, and has hardly changed its appearance for 400 million years, and is a veritable living fossil) with a total length of 2.5 meters and lived in the Early Devonian Period 390 million years ago.
From the fossils found, it can be seen that it has a hard shell skeleton, a segmented limb, and a segmented body like arthropods such as insects, spiders, and crabs. These animals are said to prey on other arthropods, even some fish.
7. Dragon King Whale
The Ryuoo whale is an extinct ancient marine mammal that lived in the late Eocene 39 to 34 million years ago. The most conspicuous feature of the Dragon King Whale is that the body is very slender, the Dragon King Whale is about 15 meters long for the female, the male is about 18 meters long, the maximum can reach 21 meters, and has a more slender body than modern whales.
The Dragon King Whale, also known as the Toothed Whale, was first found in Louisiana, USA. Archaeologists later found and preserved numerous other species in the fayum sedimentary layers of Egypt.
8. Mao Yilong
Mauilles were a large plesiosaur that existed in New Zealand during the Late Cretaceous Period. Even the largest marine reptile in New Zealand waters about 65 million years ago has only a few fossils found so far. Mao Yilong was 12 meters long and had two large flippers. Maurus was a carnivorous animal with sharp, jagged teeth in its mouth that could bite fish or squid.
Fossils of Mao Yilong were first discovered in 1870.
9. Melville Whale
The Leviathan whale is the largest species in the genus Leviathan whale and is an extinct Miocene toothed whale found in South America. Scientists speculate that melville whales are 17 meters long and weigh 65 tons.
The teeth are currently found up to 35 cm in size, but in 2013 a scorch-shaped tooth up to 40 cm long was found, so this Melville whale may have been over 17 meters tall. Melville whales are also known as top predators. It will even prey on behemoths larger than their own bodies.
Melville whales, also known as The Melville Leviathan whales, currently have few fossil samples.
10. Tailu shark
The land shark is supposed to have lived from the early Torso perm and was a carnivore in deep water. The land shark looks strange, with about 180 teeth in the jaw, which is simply a tooth monster. The most obvious difference between the pacific shark and other whales is that even if the pacific shark grows new teeth, its old teeth will not fall out but will continue to remain.
Since ancient times, stories of sea monsters have been circulating in marine waters, which are often huge, strangely shaped, and even a little scary. Those paleontologists believe that only if they really catch a sea monster, the truth of this magical sea monster mystery can be revealed to the world.
