23 million years ago, the earth rained for 2 million years, putting dinosaurs on the throne.

The planet we live on has gone through billions of years of changes and evolution before it becomes beautiful with beautiful scenery, blue sky and white clouds.

23 million years ago, there was a heavy rain that lasted for 2 million years on the earth at that time, which was called the Kanian flood event. All these were the conclusions drawn by scientists through research. It was because of this long and continuous rain that the key turning point of the hegemony change on the earth was promoted, and the dinosaurs were put on the throne.

scientists found that in the Permian period more than 2 million years ago, the temperature on the earth gradually increased. At that time, the overlord of the earth was an orc with different teeth. At that time, dinosaurs were still sauropods, and they had not yet emerged as dragons.

At the end of Permian, due to the continuous rise of temperature on the earth, the collision of continental plates triggered the continuous eruption of volcanoes, and plants became extinct on the earth due to less and less desertification environment. Many species perished and some survivors remained.

Ancient fossils and rock formations recorded the changes that happened on the earth hundreds of millions of years ago, and scientists can estimate the disasters on the earth at that time.

after the extinction, the earth entered the Triassic period with higher temperature, and the fresh water source was not sufficient. The surviving animals and species evolved to be more drought-tolerant. Among the surviving species, there were orcs who could keep constant temperature and ask questions, and they were cold-tolerant and drought-tolerant, and gradually evolved to be hot and humid-tolerant. These orcs gradually became the dominant species on the earth.

When the most drought-tolerant crocodiles once proliferated during the Triassic period, scientists even boldly speculated that for a long time, the earth was likely to be full of crocodiles, and even the once dominant animals had to retreat to the corner, because there might be too many crocodiles.

At this time, all the dinosaur groups have hard armor and scales, which can better keep the water in their bodies, and they are not afraid of dry weather. Even the lizard, the distant ancestor of dinosaurs, still lives in the arid desert area of our earth today, and still carries on the genes of ancient dragons.

because of the climate change of the earth during Triassic period, the dinosaur population also accelerated the speed and process of evolution, and began to derive various dinosaurs.

So that heavy rain more than 2 million years ago lasted more than 2 million years, why didn't it drown the whole earth? The heavy rain was caused by a big fire. More than 23 million years ago, there was a volcanic eruption in the west coast of Canada, which was called the Ranglia Volcano eruption in history. This volcanic eruption was very terrible and lasted for 5 years before it was gradually extinguished.

Volcanic eruption has affected the air and temperature of the whole earth for too long day and night, and the whole world is full of carbon dioxide produced by combustion. Because the atmospheric circulation keeps boiling, the water circulation in the atmosphere collapses.

As a result, the earth is full of storms and torrential rains, which are endless. Because the volcanic eruption temperature remains high, the rain falls to the ground and evaporates quickly, and the water vapor turns into rain again, and the falling rain evaporates and then turns into rain. In this way, the terrible heavy rain that has not stopped for 2 million years has been repeated on the earth.

In such an extreme climate, many plants and animals have been knocked down by the rain, and the remaining plants have been eliminated by species and can flourish. The surviving species have also begun to evolve characteristics that are more suitable for the earth's environment.

As a branch of the Dragon, dinosaurs have accelerated their evolution. Some of them have long necks and become herbivores who eat leaves, while others have sharper teeth and claws and become carnivorous dinosaurs. In order to survive on the earth, they show their abilities and evolve different characteristics and forms.

scientists found from ancient fossils that before the 2 million-year heavy rain, the number of dinosaurs in the region was only about 5%, but after the 2 million-year heavy rain, the number of dinosaurs on the earth occupied 9% at once, and jumped over the orcs to become the overlord on the earth. This heavy rain, which was a disaster for many creatures, sent dinosaurs to the throne and has evolved into various dinosaurs for hundreds of millions of years.

For hundreds of millions of years, there were no natural enemies, and they ran freely in any area suitable for dinosaurs to live on, until the asteroid hit the earth, which led to the extinction of dinosaurs on the earth.

Our earth has a mysterious evolution process, which has been persistently studied, inferred, guessed and discovered by scientists. For the dinosaur, a species that has occupied the earth for hundreds of millions of years, there are still many unsolved mysteries. In the more developed future of science, perhaps scientists will gradually unlock more secrets of dinosaurs, and thus solve the mystery about the evolution of species on the earth that was dusty hundreds of millions of years ago.

paying attention to the biological evolution of the earth is actually paying attention to human beings, and studying dinosaurs and prehistoric species is also helpful to solve the mystery of the origin of life on earth.
