Shark teeth were discovered millions of years ago, and when can it be traced?

According to the latest news reports from foreign media, the Nautilus exploration team found a giant shark tooth that is millions of years old, and the huge sample is stuffed under an iron-manganese coating, which can be seen that the teeth of this giant shark have been accumulated under a long period of seawater immersion, and the research team believes that this tooth should belong to the notorious megalodon, and this species of megalodon can be traced back to the Middle Ages 15 million years ago to 2.6 million years ago in the earlier renewal of the world, It is the apex predator of the seas and one of the most powerful creatures in its life.

In recent years, whale fossils have been found in many places, and there are scars caused by the attack of the megalodon, indicating that the distribution of the megalodon is very wide, why extinction is still an unsolved mystery, however, the megalodon itself has been tired as food, after the two episodes of the sea water changed, it is not suitable to survive in the sea water for a long time, and the whales have fled to other seas to live in order to escape the pursuit of the megalodon, and the megalodon has become extinct because of the lack of food. However, it is also because the megalodon itself is less adaptable to the sea water at the poles and cannot develop new food, which led to its own extinction.

Megalodon has the meaning of big tooth in Greek, because the average length of this shark is about 14 meters, about 40 tons, and the fossilized vertebrae of some of the vertebrae of the megalodon found today are estimated to be about 18 meters and weigh 50 to 70 tons, and it is also one of the largest marine predators in history, and it is also the largest fish.

Megalodon as the strongest bite on the earth, it is estimated that its bite force is about 20 tons, it can be said that his oral feeding ability has surpassed the Tyrannosaurus rex, and can even easily bite the ribs of whales, megalodon lived in the late Miocene 15 million years ago and the early Pleistocene 2.6 million years ago, and was also praised by many paleontologists as the most powerful creature on the earth. It's enough to see that this huge guy is very scary.

An ocean expedition has uncovered an absolute unit of shark tooth that may date back millions of years to the days when giant predators roamed the oceans.

Dating back to the Cambrian period, this shark was also a strong man at the time, and could eat quite a few small fish.

It should not be alive, this fish has been going through it for a long time, and now the natural environment has changed a lot, it should not be alive. It is likely that a century-old megalodon will exist on the seabed. Based on the current species, the shark is now extinct, but it cannot be ruled out that it will survive in places where we cannot detect it.

I believe that many people are very familiar with the name "megalodon", but they have only seen it in the film, it is a very terrifying giant Anyang creature, and the knowledge of this species is all calculated.

First, an ocean expedition discovered a shark tooth dating back millions of years, which they called a "remarkable discovery", and although the size of it was not revealed, it was definitely a big deal compared to the human hand. The researchers also treated the tooth specifically to preserve it for a longer period of time. Nodules around shark teeth have been exhibited in a museum in London, and the tooth may be 25 million years old.

Secondly, in fact, we don't know much about the sawtooth shark, after all, it has long been extinct, as the top predator in the ocean, scientists have calculated that the megalodon may be able to easily swallow the prey as big as a killer whale, and its bite force can even reach 20 tons, exceeding the ancient Tyrannosaurus rex, and even the ribs of the whale can be easily bitten. These teeth can be used to calculate the age of the megalodon, its size, etc., and perhaps there is a series of stories behind it waiting to be discovered.

Finally, because the fossil came from a deep-sea area in western Hawaii, the team did not find a single tooth hidden in it at first, and it can also be judged from the location of the discovery that the megalodon used to live in the environment and its habits. So this tooth is just the beginning of the research, but no matter what, it's like a work of art, and I'm impressed after looking at it. There is a great deal of curiosity about this extinct creature, and it is believed that they can discover more new knowledge through this tooth.

This discovery means that there were megalodons in the deep sea millions of years ago, allowing these people to study the origin of megalodons and when they appeared.

The discovery of a tooth by the expedition at a landlubber meant that there was a new historical specimen relic in the marine domain.

This discovery can allow human beings to fill in the gaps in related field knowledge, and it can also allow us to understand the ancient biological history more clearly, and more clearly understand the ancient world.

Living from the Late Oligocene 28 million years ago to the Early Pleistocene 1.5 million years ago, the megalodon was the ultimate predator of its age.

Megalodon, which means "big tooth" in Greek. This shark is about 15 meters or even longer and weighs about 40 tons. Later, a larger Megalodon tooth was discovered, and scientists speculated that it was 19 meters.

Weighs up to 70 tons. It is one of the creatures with the strongest biting power in the history of the earth, with an average bite force of 26 tons and a maximum bite force of 28 tons, and its teeth bite power far exceeds that of Tyrannosaurus rex cubs. It is easy to bite the hardest skull of a whale.

Megalodon is also known as Megalodon.

The first giant shark found in China 100 million years ago is called the valve tooth shark, and the discovery of this fossil provides important fossil evidence for the migration of this shark.

1. The <> of the valvetooth shark

The valvetooth shark is a type of cartilaginous fish that lived mainly in the Carboniferous to Permian periods (about 360 million to 250 million years old), and its teeth were similar in size to the teeth of today's great white sharks, so it can be speculated that the valvetooth shark was a prehistoric giant shark that could grow to three to five meters in length.

The petaltooth shark fossil is a worldwide species that is widely distributed in many parts of the Northern Hemisphere, such as England, Scotland, Ireland, Italy, Belgium, Russia, but it has not yet been found in the Southern Hemisphere.

2. The significance of discovery <>

There are two important implications for this discovery:

1. Evidence of migration.

Fossils are an important basis for studying the living conditions of animals at that time, and this fossil discovery strongly proves that this species of shark has a certain migration behavior in ancient times, which provides an important basis and reference value for scientists to delineate its living range.

2. The way of eating.

Among the existing fossilized teeth, the unique morphology of the tooth suggests once again that it may have been an alternative way of survival: the edges of the bladed teeth are lined with many vertical grooves, along with large biting surfaces, which may be more suitable for biting the muscle tissue of its prey.

This unique feeding method is similar to that of modern great white sharks, and scientists speculate that the evolution of great white sharks may have come from this, so the results of this discovery are very significant, and provide strong evidence for the progress of sharks as a species.

3. Fossil protection <>

Fossils are of great significance to the study of the whole biology, we should correctly excavate and use fossils, instead of reselling fossils, and severely crack down on various behaviors and channels of reselling fossils, so that our next generation can master more biological knowledge.

Valvetooth Sharks are a very mysterious group of eucartilage, with only 17 genera and species described. In the 50s of the last century, Mr. Yang Zhongjian, the founder of vertebrate animals in China, discovered the earliest fossil of valvetooth shark in China and named it Xingguo petaltooth fish. However, this specimen was re-examined in 1978 and reclassified to the mid-mandibular teeth of another large genus of the order Vallodont.

The seven tooth fossils found in the Yangquan Qian limestone were determined to be the Ohio valvetooth shark in the genus Valvetooth in the family Valvetoothidae, which is a true member of the genus Valvetooth. This discovery refreshed the fossil distribution record of the genus Valvetooth in the world, revealed that the Vallodon shark is likely to be a kind of pelagic fish that is good at swimming and spreading, and is also of great significance for the study of Permian marine biodiversity and the analysis of the indicator paleoenvironment in North China.

According to related reports, China has discovered the first 20.9 billion-year-old fossil of a prehistoric giant shark braided tooth, and experts say that this discovery allows us to spread his geographical range in the northern hemisphere and provides important evidence for his migration. Yes, many people think that their living environment is fixed and they do not have the ability to migrate, and if we still maintain this kind of thinking, then it is naturally very wrong, and the discovery of this shark fossil here is a good evidence of this concept. It's true, it's actually normal, after all, for this species, with the change of times, their living environment is also changing, so they need to keep looking for and choose the right environment for themselves.

In this way, their own species can be better preserved, which is the innate habit of any species, so they have the ability to do this and prove that they have done this kind of thing through real-time evidence. <>

Of course, there are such words nowadays as a reference, which can better convince this matter. So what he means to us is extraordinary, and every time we make a new discovery, we make a difference in our civilization. After all, we have not experienced these ancient civilizations, and our knowledge of them is only on a few records.

Nowadays, it can be well confirmed through this comprehensive material, so it is naturally more conducive to our exploration, and it is also very conducive to the inheritance of these civilizations. Therefore, for all of us, we must preserve these relics of civilization, because its value is very great, and its significance to us is also extraordinary. <>

So I hope the relevant departments can get attention, because these things are very important to us. And it is also closely related to our lives, only if we can really pay attention to it, we will find a way to pay attention to him, in order to really better protect him, and thus avoid some unnecessary harm.

This major discovery and research in the field of paleontology has provided important fossil evidence for the migration of vallodon sharks across the Paleo-Tethys Ocean, indicating that valvetooth sharks have the ability to migrate across the oceans and were apex predators with strong swimming ability in ancient oceans. The achievement** was jointly completed by Gai Zhikun, associate researcher of the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences (Institute of Paleovertebrate of the Chinese Academy of Sciences), Bai Zhijun of Yangquan Municipal Bureau of Planning and Natural Resources, and Zhang Junwen of Yangquan Branch of the Second Geological Survey Institute of Shanxi Province.

Experts interpret from this fossil that the ecological environment of Yangquan more than 200 million years ago is very suitable for the survival of all kinds of marine organisms, and the valve tooth shark is not only found in Europe and the United States, but also in China and Japan, indicating that it has the ability to migrate across the ocean and is likely to be a strong predator.

This is a very significant discovery that provides significant fossil evidence that represents the animal's ability to cross oceans.

The discovery of the valvetooth shark in China indicates that it has the ability to migrate across oceans, migrating from distant areas such as Europe and the United States, and is likely to be a predator with strong swimming ability.

In response to this situation, experts said that this fossil has existed for a long time, and it is also the first time that this fossil has been found in our country, and this creature generally survives in the northern hemisphere and has a particularly strong migration ability.

A boy with a sense of responsibility looks like a boyfriend, not to mention that girls like it, but I also like it. A boy with a sense of responsibility is definitely a person worth entrusting his life. He may run around the world because of a promise, and you can be completely relaxed with him.

The discovery of a prehistoric giant shark 100 million years ago in our country is a surprising discovery and a great discovery. This species is slightly different from the age in which the great white shark lived.

Megalodon is a species of shark and is considered the largest shark and largest fish in history, and is currently extinct. Lai Yan headlines.

The megalodon is 2 to 4 times longer than the great white shark, and the great white shark and the megalodon are not at all in the same weight class and are not comparable to them.

China's first discovery of the giant shark petaltooth shark 100 million years ago, for us to engage in scientific research has played a certain role, is of historical value, it is essentially different from the great white shark, they do not belong to the same species, and they appear in different ages, so this giant shark is more epoch-making significance. This is a very important discovery and has great implications for paleontological research and biological evolution. It differs from the great white shark in that it has not yet fully evolved and is a transitional species.
