The era of the dinosaurs, known as the Mesozoic Era, ended with a massive impact approximately 66 million years ago when a giant asteroid struck the Yucatán Peninsula in present-day Mexico. This event, known as the Chicxulub impact, led to dramatic environmental changes, including wildfires, tsunamis, and a "nuclear winter" effect that drastically reduced sunlight. As a result, around 75% of Earth's species, including most dinosaurs, went extinct, paving the way for the rise of mammals and eventually the emergence of humans.
