China has discovered a 2900 million year old giant shark fossil for the first time, what kind of spe

Perhaps for most people, fossils are nothing more than the corpses left behind by animals after death, but for many archaeologists, the research value of fossils has always been very high. Moreover, the understanding and research of fossils by archaeologists in China is definitely not limited to China, but also to the world. Knowing that the same type of fossil may be found in multiple countries around the world proves that the species has a certain degree of migratory ability.

Including some unearthed fossils that are hundreds of millions of years old now, this discovery is very exciting for many scientists.

Recently, there has also happened a thing that many archaeologists are more excited about, the first giant shark fossil has been unearthed in China, and the giant shark fossil has been hundreds of millions of years ago. The giant shark was named the valvetooth shark, and at first, researchers thought the shark was a benthic shellfish, but it was the discovery of this fossil that allowed scientists to see that this shark was not only a very good swimmer, but also considered the apex predator in the ocean at that time.

You must know that each type of shark actually has a relatively large classification, and this kind of shark belongs to the jawed cartilaginous fish in the classification, of course, this shark is still very different from the modern cartilaginous fish, this kind of shark belongs to the primitive cartilaginous fish, that is, the true cartilaginous shark. The fossil was found in Yangquan, Shanxi, which was very close to the equator and belongs to a shallow sea hundreds of millions of years ago, and many marine species live in Yangquan. At present, among all the eucartilaginous fish, this species is still relatively mysterious, because whether it is fossils or traces, there are relatively few found.

Judging from the size of the teeth found in this fossil, the tooth size of this shark is relatively similar to that of the great white shark, so the body length of this type of shark is likely to be between 3 meters and 5 meters, which can be regarded as a prehistoric giant shark. The reason why the fossils of this type of shark are more precious is that this kind of shark is a true cartilaginous fish, so it is very difficult to preserve the fish bones. And the teeth of this shark are also replaced for life, so this kind of fossil is extremely rare.

Scientists have only found the teeth of such sharks before, so there is no speculation about the shape of sharks.

According to the global distribution of this type of shark, including the size and teeth of this type of shark, it can be seen that this type of shark has a very strong swimming abilityAt the same time, the bite ability is also quite strong, it can bite the prey, and it will also migrate to different seas according to the season.

It is a mammalian species and a very old species, this species is generally very large and also eats meat for a living.

This shark is very large, and very fierce, and the attack power is also very strong, this fossil is now very old, but the skeleton is also very large, this shark is the top predator.

This is a species, but it is not new. Such giant sharks have appeared on the earth very early, and their size is also very huge, and they often eat some plankton, and their swimming ability is also very strong, and they belong to a kind of benthic shellfish.

This is a kind of fossil, because this fish no longer exists, and secondly, the discovery of this fossil can also promote the research of this creature in our country.

This is a valvetooth shark, and it is not usually seen in the world, it can be said to be very rare, and it is also the first time it has been discovered in 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.

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.

The Chinese research team has discovered a 20.9-billion-year-old prehistoric giant shark fossil in the newly completed chemical study of limestone layers before the second grade in Yangquan, Shanxi Province. The greatest significance of this discovery is that it fills in the gap of ancient animals, so that we have taken the study of prehistoric animals one step further, and filled in the blank of biological evolutionary history with a new animal.

Benthic. 1. Fossil research.

Through the study of the petaltooth shark fossils, we know that the halftooth shark has the ability to migrate across the oceans and was the apex predator in the ancient ocean. It has excellent swimming skills, easily catches up with its prey, and even crosses oceans to hunt and kill its prey.

2. Fossilized teeth of a half-toothed shark.

The Chinese fossil of the petaltooth shark was discovered by Mr. Yang Zhongjian in the 50s of the last century, and the researchers pointed out that the discovery of seven petaltooth shark fossils in the limestone in front of Yangquan is enough to prove that the swimming ability of the petaltooth shark is not the bottom suction crustacean as originally thought. The tooth shark also had teeth similar to those of modern great white sharks, which can lead to a body size of between three and five meters. The fossils of the hemidondon are distributed in major regions of Europe and North America, and this shark has not been found in the southern hemisphere.

Conventional wisdom is that the valvetooth shark is a slow-moving, rock-carved fish, but the fossils found this time suggest that it is a top-notch carnivore, the modern equivalent of the great white shark.

3. Yangquan is a shallow sea near the equator.

The site of the discovery of the petaltooth shark fossil is Yangquan, which may have been a shallow sea near the equator in ancient times. But fossils of so many sharks will not be found. In addition, the Yangquan area has formed many times of alternating sedimentary sedimentary limestone sandstone coal seams, which also proves that in ancient times, this area went through many vicissitudes of life and finally became what it is today.

The discovery of not only valvetooth sharks but also other related biota from the pre-limestone formations of Yangquan is enough to show that in ancient times it was a warm and translucent sea, which was very suitable for the survival of various marine life.

It can help to study the types of creatures in prehistoric China, and through the fossils of sharks, it is possible to infer the topography of prehistoric Chinese territory, as well as the prehistoric maritime civilization.

This major discovery is very helpful to research, first of all, it can let people understand the prehistoric civilization, can understand the specific knowledge of this fossil, and can also understand the social environment and current situation at that time through this fossil, which is of great significance to historical research.

This major discovery in the field of paleontology provides important fossil evidence for the study of the migration of valvetooth sharks across the Paleo-Tethys Ocean, indicating that petaltooth sharks have the ability to migrate across oceans.

This kind of shark is very long and very heavy, because they generally have very large teeth, very large size, and often attack other creatures in the sea, so we call it "the top predator of the sea", because they do survive in the sea, and all other sea creatures are afraid of it, and they are also very tough. According to statistics, their teeth are very sharp, so they are able to bite more animals and food, and it is said that they can easily bite the ribs of whales.

Such sharks, their teeth are very large, and the teeth are also very long, generally can reach 18 centimeters, several times that of other fish, when these sharks feel hungry, they can prey on other creatures in the ocean at any time, they especially like to prey on cetaceans, the small fish and shrimp in the ocean are not the opponent of the giant shark, at that time in the marine life, it has no opponent. It feels like it's the king of the ocean.

The predation method of the giant shark is still very cruel, generally in the face of weaker creatures, they will take a shortened distance, and then attack quickly, and then these creatures become the food of the giant shark, when facing relatively large creatures, they have changed their attack strategy, I have to say, the giant shark is still relatively intelligent, and is more intelligent, at this time the giant shark will attack the tail of other creatures first, because this place is the weakness of other creatures, only the weakness of these creatures is found, Then when other creatures can't parade, these creatures are called the contents of the giant shark.

But now the giant shark has become extinct, the reason for extinction, the main reason for extinction, is because of the pollution or deterioration of water quality, the giant shark is not adapted to survive in this environment, so it eventually leads to extinction, in fact, there are many organisms in the world that are extinct, are caused by the pollution of our environment, so as an individual, we should reduce the littering of garbage.
