Meteorites make dinosaurs extinct

Scientists have come to the final conclusion that a giant meteorite fell to Earth as the cause of the extinction of dinosaurs 65 million years ago.

Scientists also rejected the hypothesis that the extremely powerful volcanic eruptions of 1.5 million years have made this giant animal disappear.

A group of 41 specialized scientists such as archeology, geological chemistry, geological physics, climate modeling from Europe, Canada, Mexico, the US and Japan summarized the data they collected in over the past 20 years and have drawn conclusions in the international "Science" issue on March 5.

Traces of a massive meteorite fall 15 km in diameter were discovered on Mexican territory, dating to the time of the horrific event that ended the 160 million years of dinosaur dominance on Earth.

At the same time on the land of present-day Decan plateau of India, there were continuous eruptions of volcanoes. Both the meteorite fall and volcanic eruptions can obscure the sunlight, cooling the temperature of the Earth and causing the destruction of many species.

Scientists say studying the ancient underground deposits shows that the destruction of the Cretaceous plants and animals at 65.5 million years ago was immediate and did not last long, proving the cause This disaster is a meteorite, not a volcano. Because volcanoes erupted before the extinction of the dinosaurs for half a million years without any significant impact on the flora and fauna on Earth.

According to scientists, the giant meteorite that has fallen to Earth has caused huge fires, earthquakes of more than 10 Richter scale, continental slide and tsunami battles. The energy of this collision is billions of times the energy of Japan's Hiroshima atomic bomb blast.

Modeling of atmospheric processes shows that the fall of meteorites makes fire in the atmosphere the amount of sulfur, ash more than volcanic eruptions, which caused an unusually long and destructive Winter about half of species on Earth.

This horrifying event paved the way for a new era, the domination period of mammals on the planet, including humans.
