Detailed explanation-1: -Sixty-six million years ago, dinosaurs had the ultimate bad day. With a devastating asteroid impact, a reign that had lasted 180 million years was abruptly ended.
Detailed explanation-2: -This impact made a huge explosion and a crater about 180 km (roughly 110 miles) across. Debris from the explosion was thrown into the atmosphere, severely altering the climate, and leading to the extinction of roughly 3/4 of species that existed at that time, including the dinosaurs.
Detailed explanation-3: -The asteroid impact and its aftermath caused what has become known as the Cretaceous-Paleogene (K-Pg) mass extinction event, killing off three-quarters of species on Earth and leaving its signature scattered throughout the geological record.
