Dinosaurs became extinct because of a giant asteroid and supervolcanoes
Why did dinosaurs become extinct? The answer is because a giant asteroid hit the earth. The aftermath of which destroyed them.
Scientists are now claiming they were also killed off by huge supervolcanoes known as the Deccan Traps, in what is now northern India. These doubled their eruptions within 50,000 years of the giant asteroid hitting the earth.
The latest theory that is published in the Science magazine says the asteroid or comet that hit the earth around 66 million years ago caused a huge crater 180km (110 miles) wide off what is now the coast of Mexico.
