Wang Xiaoshan finally dug up fossils, and the audience in the live broadcast room saw the fossils in the pit at a glance.
Some staff working in the barren mountain went to the pit dug by Wang Xiaoshan to wait for Wang Xiaoshan to come out.
Wang Xiaoshan cleaned the soil around the fossils in the pit for a while. He saw that the fossils excavated this time were not very big, and he could carry them out of the pit alone.
Wang Xiaoshan simply cleaned the soil around the fossils at the bottom of the pit. After confirming that there were no fossils, he came out holding the fossils.
At this time, more than a dozen people gathered around the pit, and everyone wanted to see the fossils excavated by Wang Xiaoshan as soon as possible.
Wang Xiaoshan took the fossil and went directly back to the camp. The fossil was not big and he didn't want to show it to the audience in the mountain. He would go to the camp down the mountain and let everyone take a closer look.
"Captain Shi, please find someone to fill the hole I just dug!" Wang Xiaoshan returned to the camp and said to Captain Shi.
Captain Shi: "Okay, I'll make arrangements now."
Wang Xiaoshan took a brush and carefully began to clean the soil on the fossils. There were many tools in the camp, and he could quickly find whatever tools he needed.
It took about a quarter of an hour before Wang Xiaoshan finally cleaned up the fossil.
Everyone at the scene was confused when they saw the fossil. No one knew what it was that Wang Xiaoshan dug up this time.
Everyone looked at me and I looked at you. No one spoke. Everyone was waiting for Wang Xiaoshan to announce the answer and clear up everyone's doubts.
More than a dozen pairs of eyes were all staring straight at Wang Xiaoshan. Everyone's eyes seemed to be saying: "Tell us quickly what is this?"
Wang Xiaoshan took the camera and let the audience in the live broadcast room take a look at the fossils he dug up this time.
He was not in a hurry to tell the current people what he had dug up. Everyone had been waiting for such a long time, and the last few minutes were not missing.
"Dear viewers, this is the fossil I just dug out of the pit."
[Lao Wang is as fast as before. If he says he can dig it out on the same day, he will definitely dig it out on the same day. Lao Wang is so powerful! 】
[This time I was fooled by Lao Wang. What kind of fossil are you digging up? No matter how I look at it, it doesn’t look like a fossil at all!]
[Could it be an ancient gear? The spiral arrangement of these circles has similar gaps. Anyway, it doesn’t look like something from ancient times to me. 】
[If you look closely, it looks like a spiral tooth. Were there dinosaurs with long spiral teeth in ancient times? Or is this an ancient snail? 】
[The things Lao Wang dug up became more and more weird. Suddenly I felt that I had read too few books. I had no idea what Lao Wang was showing me. 】
The fossils Wang Xiaoshan dug up this time stumped everyone. No one in the live broadcast room knew what he dug up this time.
Wang Xiaoshan had just said that what he dug out was a fossil, but some viewers felt that what he dug out this time didn't look like a fossil at all.
On the contrary, it is a bit like a modern gear, going round and round. When the audience imagines how it turns in circles, they feel that the possibility of gears is very high.
Various answers were flying in the live broadcast room, and the audience began to guess what kind of animal Wang Xiaoshan dug up this time.
The audience can be sure that what Wang Xiaoshan showed everyone is definitely not a plant. Since it is not a plant, it must be an animal. There are so many kinds of ancient creatures. If you guess more, you will be able to guess it.
"The fossils I dug up this time are shark fossils, and what you see now are shark teeth."
What Wang Xiaoshan showed the audience was the tooth of an ancient shark. This tooth is 60 centimeters long and is a spiral tooth.
Spiral-shaped teeth, the teeth in the center of the spiral are small and the teeth on the outside are large.
After hearing Wang Xiaoshan's answer, the staff at the scene were confused again. This was the first time they had heard of a shark with long spiral teeth.
In everyone's mind, whether they are ancient dinosaurs or modern animals, their teeth are curved in the mouth.
In people's minds, the teeth of most animals are similar, some are big and some are small, but there is absolutely no animal with spiral-shaped teeth.
The on-site staff couldn't figure it out. They were close, and through what Wang Xiaoshan said, they could now see that this was indeed a fossilized tooth.
But the teeth spinning in circles are hard to accept. Anyway, no one on site believed the shark’s teeth this time.
[Shark? Megalodon is powerful enough, right? Its teeth are similar to those of a great white shark, but its bite force is stronger. I don’t find the teeth to be strange. 】
[The teeth are as long as a tape measure. I can’t imagine this is a shark. I would be more accepting if it were a tape measure!]
[Could it be possible that the teeth were straight when they were alive, and then curled up after death? And the teeth may be big or small, so this possibility is very high. 】
[It may be from a shark. Shark teeth are often used and fall off easily, so they evolved into a spiral shape to replace them. Normally, only a few need to be exposed! 】
[Why do they have such teeth? These teeth are not suitable for eating fish. This kind of shark cannot survive by eating krill!]
The audience gave several examples of ancient marine animals in the live broadcast room, and the audience could not figure out why they had such teeth.
An audience member said that this tooth looks like a tape measure. This description is very appropriate. It is really similar to a tape measure, with circles and circles, but this tooth only has three circles.
Some viewers boldly speculated that sharks' teeth used to be straight but became curly after death.
The outer ring of the spiral-shaped tooth that Wang Xiaoshan showed the audience is indeed very large. If it were straightened, it would not fit into the shark's mouth, unless the shark had a long mouth.
Some viewers who believe they are shark teeth have begun to speculate that these teeth are somewhat consistent with the characteristics of sharks.
Sharks waste teeth, which can be saved if they grow into a spiral shape. You only need to replace a few teeth at a time. Only by protecting the teeth can you hunt better.
Of course, this kind of teeth also has disadvantages. It is unable to capture large prey and is inconvenient when eating.
"Let me tell you, the name of this shark is Helicoprion. It is between 7 meters and 12 meters long. It is a veritable giant beast in the sea."
This chapter is not over, please click on the next page to continue reading! "The teeth of the Helicoprion shark are wrapped in the lower jaw!"
After hearing the name, everyone started to think about the position of the teeth. It is easy to imagine a shark's head with a spiral tooth.
Everyone has never seen this kind of dinosaur, so we can only listen to what Wang Xiaoshan said. His credibility is very high, and everyone is willing to believe what he says.
[The lower jaw of this shark is wrapped with spiral teeth, so how does it eat? A shark that is more than ten meters tall must eat a lot every day. It is a bit difficult to eat meat with just these teeth. 】
[This kind of gear teeth are not suitable for chewing meat. If you eat meat, it will easily turn into foam. In that case, it will not be convenient to eat? 】
[Such a weird tooth is really confusing. Lao Wang, are these teeth from other animals? This kind of teeth is not suitable for sharks!]
[This kind of teeth is not suitable for any animal. It is inconvenient to eat meat and plants. It is just like a saw. 】
[Today was really an eye-opener. Sharks have spiral teeth. I just asked people around and no one believed it. 】
The audience really couldn't figure out how the Helicopteron shark could eat with such a special tooth.
With such a large body, it must eat a lot of food every day. With these teeth, viewers really can’t figure out what exactly the Helicoprion eats every day.
Some people think that such teeth are not suitable for sharks. Sharks are carnivorous animals, and spiral-shaped teeth are inconvenient for eating.
It might be better if other animals have such teeth. Anyway, sharks have spiral teeth. No matter how you think about it, it doesn't match.
Not to mention the audience in the live broadcast room, even Li Miaomiao, who follows Wang Xiaoshan every day, is a little confused.
Li Miaomiao followed Wang Xiaoshan every day, whispering and watching, but she had never heard Wang Xiaoshan say that there were sharks with such special teeth in ancient times.
"The spiral tooth shark is suitable for feeding on molluscs and some small fish. This spiral-shaped tooth has its own unique way of eating."
"When the Helicoprion bites its prey, it will keep biting and releasing its mouth. The spiral teeth will gradually bring the food into the mouth in the form of a conveyor belt, and in the process the food has been cut into small pieces."
"The molluscs that Helicoprion eats most are ammonites."
The spiral-shaped teeth of the Helicodon shark have the function of 'shell-peeling'.
When the Helicopteron bites the ammonite, it uses strong biting force to continuously drag the soft part of the ammonite towards its mouth, so that the soft part of the ammonite can be easily pulled out of the shell.
Helicoprion can eat an entire "snail" without using any tools, and people also gave it the nickname "ammonite can opener".
[Ammonites were the overlords that once ruled the oceans. Unexpectedly, they were mercilessly ravaged by the Helicoprion Shark. It’s true that one thing defeats another. 】
[After listening to Lao Wang’s introduction, I discovered that the Helicopteron shark is a master at eating snails. Even though their teeth are not very long, they don’t need toothpicks at all to eat snails.]
[Ammonites in ancient times had a hard shell, and only those with spiral-shaped teeth like the Helicoprion shark were suitable for eating. It was really hard for other animals to eat them. 】
[The teeth of the Helicoprion shark are only suitable for eating molluscs such as ammonites. It would be difficult to eat other animals. The food is too simple and is not suitable for living in nature. 】
[Speaking of Lao Wang, why did you dig out just one tooth? What about the head? What about the body? Why didn’t you dig out any other parts of the shark? 】
The audience was confused even if Wang Xiaoshan didn't introduce it. By the time he finished the introduction, the audience could already imagine how the Helicoprion shark eats. The eating method is easy to figure out.
To put it simply, the teeth of the Helicopteron are like toothpicks, forcibly pulling the flesh of the ammonite out of the shell.
An ammonite without a shell is just a piece of meat, which is very convenient to eat. This way of eating does not damage the shell. If there are hermit crabs, the ammonite shell can be used as a nest.
The shell of an ammonite is very hard. If there were no spiral teeth, it would be very difficult to break the shell and get the meat out of the ammonite. The teeth might be broken and the meat would not be eaten.
However, Helicoprion is too dependent on ammonites and other molluscs, which is also the most fatal problem of Helicoprion.
During a mass extinction, ammonites were almost extinct, but the Helicopteron shark survived the mass extinction.
The Helicopteron shark, which lost a large amount of its food source, quickly moved from the top of the food chain to extinction.
This also shows that bad teeth can easily lead to extinction. Sharks like today eat a variety of foods, so they have survived to this day and have not become extinct.
"In the pit I dug just now, there was nothing else except the teeth of the Helicoprion shark. It's not that I didn't dig it, it was because there was nothing else."
"Helicoprion is a cartilaginous fish, and its entire body is almost entirely made of cartilage, just like the bones of its ears."
"This means that the bones of Helicoprion are difficult to preserve as fossils. Generally, only hard tissues such as teeth or scales can be preserved."
"So it is almost impossible to find skeletal fossils of Helicoprion in nature, which also adds a layer of mystery to Helicodon."
The lack of hard bones once again shocked everyone. No one could have imagined that such a ferocious shark had no hard bones.
There are very few large animals without hard bones. Without hard bones, it is difficult to support a huge body. From ancient times to the present, no large animal on land has cartilage all over its body.
Marine animals may have cartilage all over their bodies, and the sea has buoyancy. Their huge bodies can be supported by buoyancy.
[Helicoprion is a good breed. It is made of cartilage and is easy to eat. It saves you the trouble of picking at the thorns. If you chew the meat with the thorns, you can eat it all into your stomach. 】
[This fish is really weird, with weirdly long teeth and weirdly long body structure. It’s interesting to think about a big boneless shark.]
[Even if the spiral tooth shark was not extinct in ancient times, it cannot survive in modern times. It has no bones in its body and can be eaten by the elderly and children. Sooner or later it will be eaten to extinction. 】
[Lao Wang today unveiled the mystery of a giant ocean beast for us. If it weren’t for Lao Wang, I wouldn’t have known that there used to be such a strange shark. 】
[Although the fossils excavated by Lao Wang are not big, they are of great significance. I will go to the Dinosaur Fossil Museum next time to look for such fossils. 】
The audience thought this shark was quite interesting. It didn't even have a bone in its body and couldn't get hard.
The Helicopteron shark is very special. Whether it is its teeth or the bones on its body, it is absolutely unique in the biological world.
I don’t know if the Helicopteron shark is delicious or not. If it lived to this day, 80% of it would be eaten by humans. It would be quite comfortable to eat the fish without bones.
Wang Xiaoshan opened the audience's eyes today, and many of them wanted to go to a nearby museum to see if there was such a dinosaur.
There are fossils of Helicopteron in China, but the number is extremely small, and many of them are incompletely preserved.
The Helicoprion fossil excavated by Wang Xiaoshan retains some traces of the upper and lower jaw cartilages. If you take this back and scan it, you can clearly see the position of the Helicoprion teeth.
However, Wang Xiaoshan did not tell the audience this. He did not have the equipment at hand and could not show the scanned results to the audience. The only way for the audience to see it was to look for the shark's recovery picture online.
The teeth of Helicoprion were controversial when they were first discovered, and many paleontologists drew many restoration pictures of Helicodon.
In the minds of paleontologists, Helicoprion teeth can be found in any position, such as in the mouth, on the upper jaw, on the lower jaw, on the fins, on the belly, in any case, there are all kinds of places.
It was not until more and more teeth were dug out that the true positions of the Helicopteron shark's teeth were slowly revealed.
