Egypt dug up prehistoric screws. Experts think it was 250 million years ago, but the field trip made a joke.

Screw is a very common thing in our life, and I believe everyone will be familiar with it. As we all know, screws are the product of modern civilization, and there will be no screws in ancient times, let alone prehistoric times hundreds of millions of years ago. If someone told you that screws appeared 250 million years ago and are still preserved, would you believe it? However, it is such a bizarre thing that actually happened in real life.

Ancient Egypt is one of the four ancient civilizations. Such a magical place is full of mystery. Several prehistoric screws were found on the ruins of ancient Egypt. About four years ago, several stone explorers from China went to ancient Egypt to dig for treasures, but in the process of digging, they accidentally found several special screws. The discovery of prehistoric screws quickly caused an uproar, because as we all know, screws could not have appeared in ancient Egypt at that time, but it turns out that prehistoric screws did exist and were very old.

When prehistoric screws were discovered, out of curiosity, several explorers took these screws and went to a professional appraisal agency for appraisal. The specialty of the appraisal organization is to identify screws by carbon 14 dating method, and the results are amazing. Experts found that these prehistoric screws are really very old. It can be known from the residual carbon in the soil layer and above that these screws have a history of at least 250 million years. What is the concept of 250 million years? It was an era when even ancient Egypt and primitive people did not appear. Why did screws appear 250 million years ago? This can't help but remind people of the existence of prehistoric super civilization.

In the process of archaeological excavation, experts found that prehistoric things were very common, but this time the discovery of screws was unacceptable. It is hard to believe that there will be a prehistoric super civilization in that wild and long time 250 million years ago, and these prehistoric civilizations have also created the groundbreaking thing of screws. Therefore, relevant experts and scholars are very curious and suspicious, and they also conduct further tests on these screws. Unexpectedly, things turned upside down.

More professional experts organized a delegation to Egypt and came to the place where the screws were found. It is a black and white desert 370 kilometers southwest of Cairo, the capital of Egypt. It is a part of the Sahara desert. Because the environment is black and white, it is named "black and white desert". After analysis by experts, it was found that the black desert was a submarine volcanic zone in ancient times, because the volcanic material emitted by the submarine volcano blackened the surface. The reason for the formation of "screw" was also found. It turns out that these things are not real screws, but they are similar in appearance. At the end of Permian, that is, 250 million years ago, a large-scale volcanic eruption formed these "screws". This spiral thing is scientifically called "imaginary limonite". They are not a single mineral, but a mixture of hydrated silica and mud.

In the end, the experts finally gave the answer and revealed the true identity of the "prehistoric screw". Although we are not sure whether prehistoric civilization really exists, when we encounter some unexplained problems, we should still look at it from a scientific point of view and avoid the "prehistoric screw" oolong incident.
