Where most likely killed the dinosaurs?

The most widely accepted theory for the mass extinction of dinosaurs is the impact hypothesis, which suggests that a giant asteroid struck the Earth around 66 million years ago, creating the Chicxulub crater in present-day Mexico. This impact would have caused widespread fires, tsunamis, and a "nuclear winter" effect, drastically altering the climate and ecosystems. Additionally, volcanic activity, specifically the Deccan Traps in India, may have contributed by releasing massive amounts of volcanic gases, further destabilizing the environment. Together, these events likely led to the extinction of approximately 75% of Earth's species, including the dinosaurs.
