My Deep-sea Fishery

The formation of fossils is very complicated. It is the ultimate sublimation of the combination of three factors: biology, physics and chemistry. The whole process takes a long time and requires a combination of many factors on specific occasions, and this process is irreversible. , In the long years, once a little bit of accident happens, it will lead to the failure of fossil formation.

"It's impossible." Xiang Yang's expression changed immediately, "This straight-shelled nautilus is at least a creature that existed hundreds of millions of years ago. If it wasn't a fossil, it would have decayed to the point where there is no residue left. .”

"Then what if it wasn't a straight-shelled nautilus?"

"Or it is a straight-shelled nautilus, but it just died?" Professor Chen Yu said quietly.

"How is this possible? It is a consensus that the straight-shelled nautilus became extinct hundreds of millions of years ago." Xiang Yang immediately denied it.

"Whose consensus?" Professor Chen Yu asked.

Xiang Yang's face collapsed immediately, and he thought, isn't this the consensus that you biologists and scientists have come up with?

"We are sure that there was a straight-shelled nautilus on this planet, but so far, we have never found a straight-shelled nautilus, nor have we found a straight-shelled nautilus fossil after the Triassic, So someone put forward the speculation that the straight-shelled nautilus was completely extinct after the Triassic."

"But the entire ocean, we can detect, not even 5% of it!" Professor Chen Yu smiled and patted Xiang Yang on the shoulder, "Who dares to say that the straight-shelled Nautilus is not from the Triassic period?" The post-planet environment changed and migrated to a deeper seabed? Who knew that there would be no straight-shelled nautilus under this deep seabed? These are all unproven assumptions, the only thing we can be sure of now One point is that this straight-shelled nautilus is not a fossil, and judging from its signs of oxidation, it should not have died for more than a hundred years."

Xiang Yang's face changed, and he said in shock: "Teacher, what do you mean, the straight-shelled nautilus is not dead, but one of them has survived to this day?"

"I haven't said anything. Don't tell me what I said. These are just hypotheses, just bold guesses." Professor Chen Yu said with a smile: "However, Nautilus's strongest competitor, Nautilus, is full Horseshoe crabs can migrate from the ocean to land. Why can’t the straight-shell nautilus migrate from the shallow sea to the dark deep sea? The marine overlord who is a whole era later than the straight-shell nautilus can reproduce and survive from ancient times to today. The straight-shell parrot Why can’t snails do it? Since it’s a hypothesis, why can’t we boldly guess that straight-shelled nautiluses have never been extinct, but they have migrated from shallow seas to extremely deep seas?”

"The sea contains endless secrets." Professor Chen Yu sighed.

"Teacher, there must be a basis for the assumption." Xiang Yang said.

"This straight-shell nautilus is the basis." Professor Chen Yu said.

Xiang Yang frowned, and asked again: "Teacher, do you think there is such a possibility that after the death of this straight-shelled nautilus, it was inhabited by some kind of marine life, down from generation to generation, every once in a while? There are organisms inhabiting this straight-shelled nautilus, and for this reason, this nautilus has been preserved intact and has never been petrified."

Xiang Yang thought of the giant squid that was eaten by two humpback whales, and tried to remind Chen Yu to open up a new way of thinking for Professor Chen Yu.

Professor Chen Yu lowered his head and thought for a while, and then said: "What Xiang Yang said is indeed a possibility, but in the folk antique market, there are people who can determine the age of an object based on the degree of oxidation on the surface of the antique. , do you think those of us can’t determine the approximate age of death of this straight-shelled nautilus through the oxidation traces on its surface?”

"Of course, it is also possible that there is a special magnetic field under this sea area, or other supernatural phenomena that cannot be explained by science for the time being, which affect the oxidation rate of this straight-shelled nautilus. Sure." Professor Chen Yu explained.

Xiang Yang nodded. He is a little confused now. If Professor Chen Yu and his conjectures are true, it will undoubtedly set off a storm in the entire biological world.

However, this may just be Professor Chen Yu's conjecture. Unless someone can really find a live straight-shell nautilus, this conjecture will always be just a conjecture.

"Teacher, don't worry, I'll give the order to return to the voyage immediately, and if you still need my help, feel free to ask." Xiang Yang said.

"Don't be in a hurry to go back." Elder Peng stopped him: "Principal Chen Yu, take people to the bottom of the sea first to have a look, maybe you can find something else."

Xiang Yang knew that Mr. Peng was thinking too much, but Xiang Yang didn't stop him. Instead, he said, "Yes, teacher, maybe we can find another straight-shelled nautilus nearby, or even find one directly. Live."

"Okay, let's split up, and your people will also lend me a loan. Of course, I don't borrow it for nothing. One hundred yuan an hour per person, and I allow them to continue collecting those ordinary conch shells for you during the search process." .” Professor Chen Yu said.

"Okay." Xiang Yang immediately agreed.

The crew members, who had already been itching in their hearts, also acted immediately one by one.

Soon, the surrounding sea area was searched by the crew.

The result is naturally obvious, not to mention the live Nautilus, even the fragments of the Nautilus shell are impossible to find.

But Professor Chen Yu was not discouraged at all. He ordered someone to protect the straight-shelled nautilus tightly, and then smiled and said to Xiang Yang: "Let's go back."

"Okay." Xiang Yang agreed.

In fact, Xiang Yang still wants to stay in this sea area for a while. There are too many conch shells under this sea area. Whenever you set foot down, there is almost no place where you can not step on the conch shells. Let the crew stay here. Every time you stay below, it is an income.

Once returning this time, the scientific research ship will definitely come over immediately, not to mention blocking the entire sea area, but at least Xiang Yang will never be allowed to take the crew down to catch conch within a few nautical miles.

On the way back to the voyage in a straight line, I passed the sandy beach rich in turbot that Xiang Yang found when he led the crew to the sea for the first time. With the mentality of going down to have a look when passing by, Xiang Yang led the crew down to catch a few thousand catties The turbot came up.

The researchers, including Chen Yu, didn't say anything. They had already sent back the news, and it would take some time for the scientific research ship to come over.

And if the scientific research ship can't come, the effect of studying the straight-shell nautilus on the ship is actually the same as going back to Yanlong Village to study the straight-shell nautilus.
