Revealed the Cause of Dinosaur Extinction

Revealed the Cause of Dinosaur Extinction - A large asteroid that fell to earth became the leading cause of death of the dinosaurs. The statement expressed in a panel of scientists who followed 41 experts from around the world. In the meeting it was agreed that the mass extinction of more than half of all species on this planet, including dinosaurs and some large marine reptiles.

They concluded that the impact occurred about 65 million years ago, has cleared the way for mammals to become the dominant species on earth. An asteroid at 15 km is believed to have hit the planet earth with the power of one billion is more powerful than the atomic bomb on Hiroshima.

This resulted in the crater known as Chicxulub crater is buried beneath the Yucatan Peninsula. Asteroids, which is almost 15 times the size of a football field-exploded and crashed at high speed into the atmosphere.

In the study it is believed, the incident triggered a series of events that cause global winter and wipe out most life on earth in a matter of days.

Scientists have previously argued about whether the so-called Cretaceous-Tertiary (KT) which is caused by an asteroid or by volcanic activity in India more than 1.5 million years. For the new study, scientists analyzed 20 years of work by palaeontologists, geochemists, climate modellers, geophysicists and sedimentologists.

They concluded that the geological record shows the events that triggered the extinction destroyed marine and land ecosystems rapidly, is the impact of an asteroid. This is the only plausible explanation.

Dr Joanna Morgan, of Imperial College London, said: "We now have great confidence that an asteroid was the cause of the KT extinction. It is shrouded in the darkness of the earth and cause global winter, killing off many species can not adapt to this hellish environment."

Co-author Dr Gareth Collins, also from Imperial College, adding that the blast of hot rock and gas looking like a giant fireball on the horizon, grilling any living creature in the immediate vicinity that could not find shelter.

"Ironically, while the hell this marks the end of 160-million-year dinosaur, turns out to be a great day for mammals, who has lived in the shadow of dinosaurs before this. KT extinction was a pivotal moment in Earth's history, which ultimately paved the way for humans to become dominant species on Earth.
