Reconstructed the chronology of the events of the day of extinction of dinosaurs

The mystery of the death of dinosaurs for a long time did not giveresearchers of peace, trying to understand what exactly provoked the mass death of the giant creatures that inhabited our planet long before the appearance of man. It is believed that dinosaurs became extinct due to the fall of a huge meteorite that crashed into the Earth about 65 million years ago. After conducting research in the Chiksulub crater remaining after the meteorite fall, a team of scientists was able to recreate the chronology of the “Doomsday” of the dinosaur era.

It is believed that the mass extinction of dinosaurs occurred about 66 million years ago.

Why did dinosaurs die out?

It would seem that it can destroy hugeland monsters reaching the size of a whale? Perhaps only a huge meteorite, having a couple of kilometers in length. But even it would not be enough to turn dinosaurs into a handful of ashes.

The process of extinction of dinosaurs began long beforefalling meteorite, which only aggravated the natural process. The fact is that about 65 million years ago, in the era of the Late Cretaceous, an unexpected cooling took place, which led to the appearance of flowering plants. These two events led to the disruption of the ecosystem that was so familiar to the famous tyrannosaurs, triceratops and iguanodons. By the time of the fall of the Chiksulub meteorite, only a handful of once powerful beings remained on the planet.

Could survive such a biological cataclysmonly those “dinosaurs” who, at the time of the fall of the asteroid, were able to acquire wings that evolution had carefully equipped them with. Information about these winged creatures can be found on our channel in Yandex.Zen.

Did the dinosaurs die out at the same time?

Immediately after the fall of the asteroid, the entire planet was covered with forest fires and tsunamis, which killed 75% of all life on Earth. For a while, the planet plunged into complete darkness.

Having studied the rocks of the Chiksulubsky meteorite,The researchers concluded that after the asteroid fell, the earth around it completely evaporated as a result of exposure to thermal energy. The interaction energy of the meteorite and the ocean floor was so powerful that when it met with water, the asteroid caused a wave 1.5 km high. A giant tsunami swept across the planet at the speed of a jet plane, literally washing away everything that came in its way.

Inside the layer of dust that covered the craterkiller asteroids, the researchers found a large amount of charcoal, which suggests that after the tsunami the planet went through huge forest fires that formed the reaction of the release of sulfate aerosols, causing a long period of darkness that could drag on for several decades.

Ceratops have become one of the “centenarians” who have found the border of the Mesozoic and Cenozoic

Without solar energy inthe atmosphere of the planet, almost all the flora and fauna on the planet became extinct. Those who were able to somehow survive, formed a completely new ecosystem of the planet, which we can observe today.
