Quizplus · Accepted Answer

The leading hypothesis is that a large asteroid impact caused a massive extinction event, including the extinction of the dinosaurs. The impact site, known as the Chicxulub crater, was discovered in the Yucatan Peninsula in Mexico and shows evidence of an impact around the time of the extinction. The impact would have caused widespread devastation, including wildfires, tsunamis, and a "nuclear winter" effect from the dust and debris kicked up into the atmosphere. This would have had catastrophic effects on the environment and the organisms living at the time, leading to the extinction of the dinosaurs.
