Comet: Assassin kills the dinosaurs

American scientists announced the study of space rocks that collided with Earth 65 million years ago, causing the extinction of dinosaurs as a comet, rather than an asteroid as predicted. before.

The conclusion has been presented at the 44th Moon Science Conference and Planets, taking place from March 18-22 in Texas (USA).

Evidence of the above collision is that scientists found a Chicxulub crater with a diameter of 180km on the Yucatan Peninsula, Mexico. The team found that to create a 180-km-wide crater, the impact of a small entity with a very high movement speed was required.

It was the comet that moved at high speed when crashing into Earth that caused fires, earthquakes and tsunamis, destroying up to 70% of Earth's creatures, including dinosaurs, Professor Mukul Sharma - one of the authors of the study, working at Dartmouth University, New Hampshire State (USA) - told the BBC.
