My Deep-sea Fishery

The straight-shelled nautilus Xiangyang was actually only hidden in a seaweed bush more than a thousand meters away from the fishing boat.

There is no way, the terrain around here is open, and there is nothing particularly conspicuous that can block the line of sight. If Xiang Yang hides the straight-shelled nautilus too close to the fishing boat, it is inevitable that someone will find something wrong.

If you hide too far, it will arouse suspicion from others, why did you swim so far in such a short period of time? This is obviously unscientific.

So Xiang Yang deliberately hid the straight-shelled nautilus in a location not too far from the fishing boat, and purposely stayed on the bottom of the sea for a while, and dragged on the bottom of the sea for a while.

Professor Chen Yu and others followed behind Xiang Yang, and everyone was swimming quickly.

After a while, Professor Chen Yu's whole body was shaken. He saw a touch of white. He was shocked at first, then ecstatic, and stopped trembling on the spot.

The people behind him quickly pushed him.

Only then did Professor Chen Yu come back to his senses, he calmed down, and then he said: "Attention the photography team, remember to record every action of all of us next, we will record this precious Record it for a moment."

Those scientific researchers nodded quickly one by one.

Professor Chen Yu stopped talking and made a forward gesture.

Speaking on the bottom of the sea, even with the most advanced diving equipment, it is very difficult to do it. It is not only enough to provide enough oxygen to the diving suit, but also to eliminate the pressure of seawater on the diver's lungs. Even so, the burden on the speaker is still heavy.

Chen Yu and his scientific research team only have one set of underwater equipment that can communicate with people on the seabed. Now it is used by Chen Yu, mainly to communicate with the people on the seabed. It doesn't need to be so troublesome. Professor Chen Yu understands dumb language and sign language.

"It's a straight-shelled nautilus, my God, my god, it's really a straight-shelled nautilus, it's so well preserved, my god, it's a priceless treasure." An old biologist on board who was standing in front of the electronic display was excited. Unexpectedly, he swears, and he shouted: "Quick, give me a diving suit, I want to go down in person."

The people next to him were startled by the old biologist's words, and they smiled wryly: "Old professor, you can't go down." Just kidding, the old man is already over seventy years old. Who is responsible?

Professor Chen Yu was also taken aback, and quickly said, "Mr. Peng, you can't come down. Mr. Cai is still doing geological research in the town. I'm under the sea. If you get down, who will be in charge?"

The old man gradually calmed down, "Okay, Dean Chen Yu, but when you salvage this straight-shell nautilus, you must be careful and careful, and there must be no damage."

"Don't worry." Professor Chen Yu only said three words briefly. Mr. Peng is an authority on marine biology in China, and his qualifications and background are indeed excellent, but in this scientific research team, Professor Chen Yu is the leader. Professor Chen Yu respects Mr. Peng, but Professor Chen Yu doesn't need to promise anything to Mr. Peng when he does something. A three-word reply is enough.

"Be careful, don't break it." Professor Chen Yu directed a few scientific researchers to salvage with professional gestures. At the same time, he also asked Xiang Yang to help. The professor would not allow anyone to get close to this straight-shell nautilus. This kind of professional work can only be entrusted to professionals, otherwise it will be a great loss if it is damaged even a little.

Most people have no opinion, knowing that this thing is precious, and they are happy not to touch it.

Only Fang Youqun was a little annoyed, secretly wondering whether it was Brother Yang who discovered it, or Professor Chen Yu.

It took a lot of effort for a group of people to drag it onto the boat with great difficulty.

"Is this conch really from hundreds of millions of years ago? Why do I look like I just died?" A biologist wondered.

Professor Chen Yu also frowned, "This snail shell doesn't seem to be a fossil?"

Xiang Yang didn't speak, in fact Xiang Yang had discovered this a long time ago, he guessed that it should be the reason why the shell of this straight-shelled nautilus was inhabited by a giant octopus, but it's hard for Xiang Yang to say clearly, and this also It's just Xiang Yang's guess.

Mr. Peng was holding a magnifying glass, and his eyes were almost completely attached to the straight-shelled nautilus. While observing, his whole body was trembling with excitement, "Comrades, we have to return to the voyage immediately, and immediately let people drive the scientific research ship to transport more Professional equipment and personnel will come.”

Xiang Yang looked at Chen Yu.

I saw that Chen Yu was also staring at the straight-shelled nautilus. Although his brows were frowned, instead of objecting after hearing Mr. Peng's words, he nodded subconsciously.

"Teacher, we will see those two humpback whales soon, are you sure you want to return now?" Xiang Yang asked Chen Yu.

Chen Yu waved his hand, "There is something wrong with this straight-shelled nautilus."

"What's wrong? What's wrong?" Xiang Yang asked doubtfully.

Professor Chen Yu withdrew his gaze from the straight-shelled Nautilus, and after pondering for a moment, he said: "Scientific research and investigation are very rigorous. Before the actual experimental data is obtained, all assumptions are nothing more than bold guesses. Originally, it is impossible to communicate with outsiders. As I said, because of the experimental data as support, what I said next is very unreliable, but you discovered this snail, and you are also my student, so it’s okay to tell you.”

Xiang Yang hurriedly said: "Teacher, can't you say it? It's okay, I understand the rules, if you can't say it, then don't say it."

At this time, Mr. Peng stood up, and he shook his head and said, "Actually, it's not that we can't say this, but even if we say it, we can't be sure of the accuracy of it, so there's no need to say it, but since you asked now, And also participated in this matter, so let me tell you about it."

"Let me tell the story." Chen Yu squatted down, gently stroking the straight-shelled nautilus with his fingertips, "We now have a preliminary guess that this straight-shelled nautilus is not a fossil."

The formation of fossils is a very complicated process, which is a combination of biological, physical and chemical phenomena.

To put it simply, in the long geological age, the remains or life traces of ancient organisms were buried by sand, while the organic matter in the remains was completely decomposed, and the hard parts such as shells, bones, branches and leaves, etc. were separated from the surrounding sediments. petrified together, but their original form, and even some subtle internal structures still remain.

For a long time, people thought that living things could become fossils as long as enough time passed, but later research showed that this was a fallacy.
