The death of the dinosaurs occurred as a part of what?

The death of the dinosaurs occurred as part of the Cretaceous-Paleogene (K-Pg) extinction event around 66 million years ago. This mass extinction is widely believed to have been triggered by a combination of catastrophic events, including a massive asteroid impact near present-day Chicxulub, Mexico, and extensive volcanic activity in the Deccan Traps of India. These events led to dramatic climate changes, disrupting ecosystems and resulting in the extinction of approximately 75% of Earth's species, including all non-avian dinosaurs.
