Dinosaurs extinction is caused by meteors?

The origin of meteorites that killed dinosaurs is still a mystery, according to the results of American scientists.

Scientists believe that a meteorite with a diameter of 10 km, one of Baptistina 's fragments, a giant rock in the universe, crashed into the Earth in a massive collision 160 million years ago. and causing the dinosaurs to become extinct.

However, according to the latest research by scientists at NASA, meteorites that kill dinosaurs cannot be Baptistina's fragments.

By the data collected by the WISE telescope when observing the sky under infrared light and the measurements of the age of 1,056 Baptistina-born asteroids, scientists discovered the fragments of Baptistina was born only 80 million years ago, not 160 million years.

Amy Mainzer, one of the study authors, said: 'It takes several tens of millions of years for debris to move into resonance and fall to Earth, so meteorites killed dinosaurs 65 million years ago. years are not Baptistina's fragments'.

Accordingly, the origin of meteorites that led to the elimination of dinosaurs and many other prehistoric species is still unknown.
