Galactic Garbage Station

After Zhou Xiyi and Ye Bo's assistant left, they waited for the appraisal results.

The age identification of fossils is actually not difficult. Relative age has traditionally been determined on the basis of the formation in which it was found, but scientists have found ways to identify absolute age since people's understanding of atoms has deepened.

Substances found in nature are mostly composed of several isotopes (i.e., various atoms having the same atomic order but different mass numbers). Some isotopes are radioactive, that is, their atomic nuclei spontaneously emit radiation and gradually become another substance. For example, radioactive isotope 14C degenerates to 14N.

Each radioisotope has its own rate of transformation, which is called a “half-life” - the time it takes to halve the number of atoms in a substance. So, if we know the half-life of each isotope, it's not hard to calculate the age of an object that contains that isotope, as long as we measure how much remains of that isotope.

The two most widely used methods are 14C, which is used to identify organic matter, and 40K-40Ar, which is used to identify volcanic formations and their associated fossils. In the 40K-40Ar method, for example, argon is the decay product of the radioisotope potassium, which has a half-life of 1.3 billion years, making it easy to determine the age of the specimen. At present, the method has developed with great sophistication to identify specimens that are only about 50,000 years old, as well as those of the same age as the Earth, with minimal error.

After a while, Zhou Xilei's assistant first called back.

“Did you get the results yet?” Zhou Xi walked aside and asked in a low tone.

“The results came out, about 200 million years ago.” There was an exciting voice on the phone.

“Are you kidding?” Zhou Xi's idle pupils suddenly lit up and her voice shivered slightly. Two hundred million years ago, in other words, the late Triple Age, was a little earlier than the Jurassic age, when dinosaurs lived.

“Impossible mistake, we have identified twice, teacher, this fossil is of extraordinary value...”

“I need you to tell me.” Zhou Xileisheng was afraid that Ye Bo would hear it. He hung up the phone and pressed down his mind's excitement. He went to Su Zheng, intending to take down the fossil first.

Who knows, this is when Yebo's excited voice sounded: “What? 200 million years ago?” Yebo was on the phone, and apparently his assistant, who had also been identified, obtained the same result.

“Mr. Sue, I must bring this fossil back to the archaeological institute.” Zhou Xilei knew that the plan he had secretly taken had gone soup, and he took the first step.

“Nonsense, understand what it means to arrive first and then, it is up to me to bring it back to the Paleontological Institute.” Yebo was also excited that this spider fossil, the earliest relatively intact spider fossil ever discovered, was at least 35 million years earlier. This is undoubtedly a precious fossil of great archaeological and research value.

“So fair play, I'll give you 100,000.” Zhou Xi said idly.

“I... I give 150,000.” Ye Bo smoked the corner of his mouth and became anxious because he knew that he could not rob the archaeological institute with money, not to say that the archaeological institute had more money, but that Zhou himself was very rich this past week.

“300,000.” Zhou Xi was idle.

“Thirty-five thousand.” Ye Bo is out.

“Half a million.” Zhou Xi bluntly said, Yebotun couldn't speak, he was angry with his mustache, his face rose red, Zhou Xi chuckled, "Oh, it looks like this fossil belongs to me. ”

“Old Zhou, I think this fossil is more than that.” Su Zheng laughed.

“Nor can you say that this fossil is just a stone for ordinary people, only old things like us, so you want to sell it at a high price, which is unlikely.” Zhou Xi idly waved.

“Don't listen to him, this fossil you got for auction, worth at least a million.” Ye Bo himself can't get it, but he doesn't want Zhou Xilei to get it so easily. This unique fossil, which is expected to be enjoyed by a number of collectors, will really be sold for no less than a million dollars, and if no earlier spider fossils are found in the next few years, the price will rise.

“You old bastard, this fossil strictly belongs to the state property, can you get an auction? Bring me back to the archaeological institute to contribute to the country.” Zhou Xilei was angry, but I was really afraid Su Xin would sell it, "he said.“ A million is a million. How about Mr. Su sell it to me quickly? ”

Ye Bo stopped talking. He didn't really want Su Zhou to sell the fossils at the auction house. In contrast, selling them to the archaeological institute was much better than selling them to private individuals. He just wanted Zhou Zhou to enjoy himself.

“All right, Zhou Lao, just sell it to you for a million, but on one condition, when you don't use this fossil, occasionally give Mr. Ye research.” Su Xin said that he had just released his mental strength detection. Based on Zhou Xilei's mental fluctuations, this should be his highest price. Lift it up again, I'm afraid he won't buy it. Such a useless fossil, turning around and selling a million dollars, this business does nothing. As for speaking for Ye Bo, it is in Xue Zonghong's face.

“Well, that's okay. If you have any fossils in the future, come to me.” Zhou Xi glanced at Ye Bo and barely promised. Fearing that Su Zheng would regret it, he immediately gave Su Zheng a million.

“Thank you, Mr. Sue.” Ye Bo smiled.

“It's just a show of hands.” Su Jin smiled.

Le Guanglei and others who heard the conversation hidden in the distance couldn't help but be surprised. No wonder Su Min was so rich and could build such a building. The first floor was even reinforced with alloy plates. Turns out he made so much money, a stone could sell a million. Whenever you pick up a few fossils yourself, see if you can sell tens of millions.

“Speaking of which, this spider is so intact, it's kind of weird.” Zhou Xi held the fossil in his arms, bewildered and Ye Bo did not speak, but rarely nodded in agreement.

“What's so strange?” Su Qian asked.

“The best spider fossils found before this were buried in fine volcanic ash, so the fragile external bone marrow was not destroyed, it was just crushed, but this one, obviously not, and I don't know why?” Zhou Xilei said.

“This... you don't know I'm even more unlikely to know.” Su Zheng said this, but his heart was chirping. Is it because of the strength of the spiders of the immortal world that mortals cultivate? For example, the giant spider was thrown on his body by a rock, but he didn't die immediately, and his body was basically intact. If it had been the Earth spider, it would have been meatloaf sauce. But that reason, naturally, cannot be said.

“Well, take it back and do your research.” Zhou Xiyi greeted his assistant, picked up the fossil and left with joy. Ye Bo also left with Su Jun. Looking at the back of the two people, Su Zheng thought, I hope they don't waste too much time on it. After all, whatever they found, they are actually very deviant from the Earth.
