Dinosaurs died off during a mass extinction primarily because they were hit by a giant asteroid. This event, known as the Cretaceous-Paleogene (K-Pg) extinction event, occurred around 66 million years ago and is widely believed to have caused significant environmental changes that led to the extinction of approximately 75% of Earth's species, including the non-avian dinosaurs. Additional factors, such as volcanic activity and climate change, likely contributed to the severity of the extinction event, but the asteroid impact is considered the primary trigger.
