The mystery of the dinosaurs a long time did not give rest to researchers trying to understand what provoked the mass death of giant creaturesthat inhabited our planet long before the appearance of man. It is believed that the dinosaurs became extinct because of the fall of a huge meteorite crashed into the Earth about 65 million years ago. Conducting research in the remaining after the fall of the meteorite crater Chicxulub, a team of scientists were able to recreate the chronology of the “judgment day” of the dinosaur era.
Why the dinosaurs went extinct?
It would seem that it can ruin the vast land of monsters, reaching the size of a whale? Perhaps only a huge meteorite with a couple of kilometers in length. But even it would not be enough to turn a dinosaur into a pile of ash.
The process of extinction of the dinosaurs began long before the fall of the meteorite, which only exacerbated the natural process. The fact that about 65 million years ago during the late Cretaceous period, there was a sudden chill, which led to the emergence of flowering plants. These two events led to the disruption of the ecosystem, which was so familiar to the famous Tyrannosaurus, the Triceratops and iguanodons. By the fall of chekalovskoe meteorite, the planet had only a handful of mighty once creatures.

To survive such a biological cataclysm could only those “dinosaurs”, which by the time of the fall of the asteroid could get wings, which they had thoughtfully supplied evolution. Information about these winged creatures can be found on our channel in Yandex.Zen.
Whether extinct dinosaurs at the same time?
Immediately after the fall of the asteroid, the entire planet was covered in forest fires and tsunami that killed 75% of all life on Earth. For some time the planet was plunged into total darkness.
After studying the breed chekalovskoe of the meteorite, the researchers came to the conclusion that after the strike the ground around him completely vanished from the exposure to thermal energy. The energy of interaction between the meteorite and the ocean floor was so powerful that he met with water, the asteroid caused a wave height of 1.5 kilometers. A giant tsunami swept across the planet at the speed of a jet plane, literally washing away everything that came his way.

Inside the layer of dust that covered the crater of the asteroid-killer, the researchers found a large quantity of charcoal that suggests that after the tsunami the planet walked through the huge forest fires that formed the reaction to the release of sulfate aerosols, caused a long period of darkness, which could take several decades.
Being without admission of solar energy into the planet’s atmosphere, virtually all the flora and fauna on the planet became extinct. Those who managed somehow to survive, formed a completely new ecosystem of the planet that we can observe today.
