The extinction of the dinosaurs was caused by an asteroid that crashed into Earth 66 million years ago, in the Yucatan Peninsula: the impact wiped out 75% of living species and caused mega-tsunamis with waves hundreds of meters high. But how do we know what caused the extinction of the dinosaurs? You may not believe it, but evidence of the impact theory has been discovered in Italy, in Umbria in the Bottaccione Gorge, and has been confirmed by the discovery of the Chicxulub crater in Mexico.
