Galactic Garbage Station

After Zhou Xixuan and Ye Bo’s assistant left, they waited for the identification result.

The age identification of fossils is actually not difficult. The relative age has always been determined based on the discovery of its strata. However, since people's understanding of the atom has gradually deepened, scientists have found a way to identify the absolute age.

Most of the substances found in nature are composed of several isotopes (ie, various atoms with the same atomic number and different mass numbers). Some isotopes are radioactive, that is, their nucleus spontaneously emits radiation and gradually turns into another substance. For example, the radioactive isotope 14c turns into 14n.

Each radioisotope has its own certain rate of decay, which is called the "half-life" - the time required for half the transformation of a substance's atomic number. Therefore, if we know the half-life of various isotopes, it is not difficult to calculate the age of an object containing this isotope, just measure how much is left in the isotope.

The two methods are currently the most widely used, one is the 14c method for identifying organic matter; the other is the 40k-40ar method for identifying volcanic formations and fossils associated with them. Taking the 40k-40ar method as an example, argon is a decay product of radioisotope potassium. The half-life of this isotope potassium is 1.3 billion years, so it is easy to determine the age of the specimen. At present, the French side has developed extremely sophisticated. It can identify specimens with a history of only 50,000 years, and can also identify specimens of the same age as the Earth, with minimal errors.

After a while, Zhou Xi’s assistant first called back.

“Is the identification result coming out?” Zhou Xi took aside and asked, pressing down the voice.

"The results came out, about 200 million years ago." There was an excited voice inside the phone.

"Isn't it wrong?" Zhou Xi's leisurely pupils suddenly turned bright, and the voices shook with excitement. Two hundred million years ago, in other words, in the late Triassic, it was a little earlier than the Jurassic where the dinosaurs were.

"It is impossible to make a mistake. We have identified it twice. Teacher, this fossil is of extraordinary value..."

"Use you to tell me." Zhou Xi was afraid of Ye Bo to hear, and hung up the phone, forced the excitement of his heart. Going to Su Shi, I plan to take the lead and take the fossil.

Who knows, this time sounded Ye Bo excited voice: "What? 200 million years ago?" Ye Bo is on the phone, apparently his assistant. It was also identified and the same result was obtained.

"Mr. Su, this fossil must be brought back to the Institute of Archaeology." Zhou Xi idle knows that the plan he secretly took has been ruined, and he took the lead.

"Nonsense, I don't know what it means to come first, then I will bring it back to the Institute of Paleontology." Ye Bo is also excited. This spider fossil is at least 3500 earlier than the earliest relatively complete spider fossils that have been discovered so far. Million years. There is no doubt that this is a precious fossil with great archaeological and research value.

"So fair competition. I am out 100,000." Zhou Xi idle said.

"I... I am out of 150,000." Ye Bo’s mouth was pumping, and his heart was anxious, because he knew that with money to fight for it, he couldn’t take it. It’s not that the archaeological institute has more money, but this Lao Zhou himself is very rich.

"Thirty thousand." Zhou Xi is quiet and leisurely.

"Thirty...three thousand." Ye Bo excused.

"Fifty thousand." Zhou Xi leisurely faintly, Ye Bo suddenly couldn't speak, and he was so angry that his face was blinking and his face was red. Zhou Xixiao laughed, "Oh, it seems that this fossil belongs to me."

"Zhou Lao, I see this fossil. Not only this price." Su Shi smiled.

"It can't be said that this fossil is just a stone for ordinary people. Only us old things like it, so you want to sell very high prices, and it is not possible." Zhou Xi laid a swing.

"Don't listen to him. This fossil is sold at the auction house, at least one million." Ye Bo himself could not get it, but he did not want Zhou Xixi to be so easy to get. This unique fossil is estimated to be popular with many collectors. It is really worth selling less than one million. If no earlier spider fossils are found in the next few years, the price will rise.

"You are not dead. This fossil is strictly a state property. Can you just get it at the auction house? Bring me back to the Institute of Archaeology and contribute to the country." Zhou Xi idle, but really I was afraid that Su Shi would sell it and said, "One million is one million, how can Mr. Su sell it to me?"

Ye Bo didn't talk at this time. He didn't really want Su Shi to take the fossils to the auction house. By comparison, selling to archaeological institutes is much better than selling them to private individuals. I am happy.

"Well, I am selling a million to you, but there is a condition. When you don't use this fossil, you will occasionally study and research Mr. Ye Lao." Su Shi said, just released the mental power detection, according to Zhou Xixi In terms of mental fluctuations, this should be his highest price. If he goes up, he will not buy it. Such a fossil that is useless to oneself, even sold one million, this business is not done. As for talking to Ye Bo, it is on the face of Xue Zonghong.

"This, let's do it. If there are fossils in the future, remember to come to me." Zhou Xi took a look at Ye Bo, and reluctantly agreed to it. For fear of Su Shi’s remorse, he immediately turned to Su Shi. Million.

"Thank you Mr. Su." Ye Bo also smiled.

"It’s just a matter of raising your hand." Su Shi smiled.

Li Guanglei and others who faintly heard the conversation not far away, could not help but be surprised. It is no wonder that Su Shi is so rich, he can build such a building, and the first floor is even reinforced with alloy plates. It turns out that he is making money so simple, a stone can Sell ​​one million. When do you go to pick up a few fossils to see if you can sell dozens of millions.

"Speaking, this spider is so well preserved, it is really strange." Zhou Xi leisurely holding fossils, doubtful, Ye Bo did not speak, but rarely nodded and agreed.

"How strange?" Su Shi asked.

"The best intact spider fossils discovered before this were buried in fine volcanic ash, so the fragile outer bone marrow was not destroyed, but it was squashed, but this one is obviously not, and why is it not? Zhou Xi idle said.

"This... you don't know that I know more about it." Su Shi said this, but his heart was stunned. Is it because the mortal body of the mortal world is strong? For example, the giant spider, who was smashed on the body, did not die immediately, and the body was basically intact. If it was replaced by the earth spider, it would have been a meatloaf. However, this reason cannot be said naturally.

"Well, bring it back and study it well." Zhou Xi idled his assistant, picked up the fossils, and left happily. Ye Bo also left with Su Shi. Looking at the backs of the two, Su Shi thought, I hope they don't waste too much time on it. After all, no matter what they are researching, they are actually far from the earth. (To be continued.)
