Why did the dinosaurs go extinct one by one 6,300 years ago, and how did the fossils form?

It was the universe that dropped a stone down, deformed the atmosphere, and entered the ice age, because the dinosaurs were hot-blooded animals, they could not survive the long era, and at the same time, the violent movement of the earth's crust also accelerated the death of the dinosaurs. Fossils are a pile of bones left behind by the decay of animals after death, and due to the constant movement of the earth's crust, the bones are buried below the surface of the earth, and fossils are formed over a long period of time. (The main component of the bone is cacao3, which is the same as geology, so it can be preserved below the surface.) ）

Meteorites hit the earth, the sky was covered with dust, plants were left without food, and the dinosaurs became extinct. Fossils are bones that have been formed over thousands of years. (Dinosaurs are cold-blooded!) ）

From elementary school, we know that humans evolved from apes. The earliest apes were like apes, but they could walk upright and use a few simple tools, which was a qualitative leap from apes to humans. The evolution of Australopithecus in humans today also follows the rule of survival of the fittest.

In order to survive, they began to hunt with stone tools and began to walk alone. After a long period of baptism, he slowly evolved into the person he is today. Reflective humans have become the higher animals at the top of the food chain.

But have you ever thought of another question, why did dinosaurs not become "feared people" after they ruled for hundreds of millions of years?

Most of what we know about dinosaurs comes from books as well as science fiction movies, and if possible, you can visit the Museum of Natural History or the Dinosaur Museum. Adults and children alike marvel at this huge and amazing species. Sigh that dinosaurs existed on Earth hundreds of millions of years ago!

It used to be the overlord of this world. They were born 100 million years ago and became extinct 65 million years ago. He lived on Earth for hundreds of millions of years.

On the contrary, it takes no more than four million years for humans. Theoretically, dinosaurs existed much longer than the ancient Australopithecus evolved in humans. Why don't they evolve?

In fact, dinosaurs were also evolving. Modern scientists have discovered that there was a small dinosaur called "Toothtooth Dragon", although its size was insignificant compared to other large dinosaurs. But they have relatively large brain powers.

It is comparable to the current parrot. The parrot is a particularly intelligent bird, and its IQ is equivalent to that of a 3- to 4-year-old human. From this point of view, the IQ of the Broken Tooth Dragon is also relatively high.

Dinosaurs at the time tended to evolve highly intelligent creatures, but it took longer. But they did not expect further development. Natural disasters led to the extinction of the species.

Maybe that's God's providence! As a result, the dinosaurs of the time tended to evolve highly intelligent creatures, but it took longer. But they did not expect further development.

Natural disasters led to the extinction of the species. Maybe that's God's providence!

I don't think they're very suitable for living on Earth, so they haven't evolved.

Because at that time, it is simply the law of the jungle, and the world does not need any wisdom.

When it comes to dinosaurs, although we haven't seen this prehistoric creature with our own eyes, we will love it more and more. From childhood to adulthood, we have been exposed to a lot of knowledge about dinosaurs, whether in textbooks or extracurricular activities, and we have also watched a lot of movies about dinosaurs, and countless picture books.

Why dinosaurs appeared so early, but did not evolve into "dinosaurs" In fact, there is a tendency.

This should be because the dinosaurs had no concept of humans at that time.

"Dinosaur DNA" is suspected to have been found in fossils 70 million years ago, scientists may crack the secret of "dinosaur DNA".

1. Scientists have found suspected "dinosaur DNA".

A research team from the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences has made a major new discovery. They areA 70-million-year-old fossilized duck-billed dragon cartilage, fragments of suspected "dinosaur DNA" were found.

Dinosaurs were creatures that lived hundreds of millions of years ago, and were the overlords of the earth, ruling the earth for hundreds of millions of years. The only footprints of dinosaurs can be found today are fossils, which have allowed humans to piece together the lives of dinosaurs.

There are different theories about the cause of the extinction of the dinosaurs, some say it was because of the volcanic eruption caused by the comet hitting the earth, some say it was because of climate change, but these are all human assumptions, and there is no correct answer to the real cause.

The discovery of "dinosaur DNA" from dinosaur fossils was a major discovery, and complete mammoth DNA had been discovered before, but there was no enthusiasm for it since then.

Second, scientists may crack the "dinosaur DNA".

Dinosaurs are creatures that lived hundreds of millions of years ago, and for various reasons, dinosaurs eventually disappeared.

In many movies, there are similar things about using dinosaur DNA to resurrect dinosaurs, but in these movies we can see dinosaurs that are treated as animals and end up attacking humans. Dinosaurs have disappeared creatures, and humans are not returning to nature.

Scientists found that this group of dinosaur DNA was not complete, but fragmented, and claimed that it was suspicious, that is, whether it was dinosaur DNA or not remains to be determined. After all, this fossil has been around for 70 million years, and it is really difficult to preserve it until now unless it is in the permafrost.

Next, scientists may crack this DNALet's determine if this set of DNA is a dinosaur. Some people are looking forward to resurrecting ancient creatures, after all, many people are curious about dinosaurs.

III. Conclusion. Scientists have found fragments of what appear to be "dinosaur DNA" in dinosaur fossils from 70 million years agoScientists are likely to continue to study and decipher this set of DNA to determine whether it was a dinosaur or not.

Scientists can study the genes of dinosaurs, how dinosaurs became extinct, and potentially recreate dinosaurs.

I think scientists will be able to study this thing, and they will be able to understand what dinosaur DNA is like.

According to scientists' analysis, the earth has a history of at least 4 billion years, this is because we found that many rocks are as old as 4.6 billion years after we obtained rocks on the moon, and the moon is a satellite of the earth, so the age of the earth must not be less than that of the moon.

In such a long time, many strange animals have been born, and many traces of animals have long disappeared with time, but the bones of some animals will be preserved in the form of fossils, and the dinosaur fossils we see are one of the creatures that lived on the earth, and they lived on the earth tens of millions of years earlier than us humans.

Argentinosaurus is about 65 million years old and belongs to the titanosaur family, which is very large in size, with a body length of 30 meters. Weighing about 60 to 100 tons, it is ten to sixteen times taller than an ordinary elephant.

The North Shield dinosaur fossil is said to be one of the best-preserved dinosaur fossils ever discovered, and we can also find food in his stomach from the fossils.

A prehistoric giant tortoise that can grow to the size of a car.

The mummy dinosaur fossil, discovered and excavated by fossil collector Charles Sternberg in 1908, is special about its **, tendons, nostrils and many other body parts.

Sea lily fossils, this animal can also be found in the ocean similar species. The terrifying shape made it the inspiration for the monsters in the movie "Alien".

In the Egyptian desert, there is a place called Valley of the Whales, where hundreds of fossil specimens have been found.
