why they died. The Cretaceous . extinction event, or the K-T event, is the name given to the die-off of the dinosaurs and other species that took place some 65.5 million years ago. For many years, paleontologists believed this event was caused by climate and geological changes that interrupted the dinosaurs' food supply. How long did ]it take for the dinosaurs to die after the asteroid?

When a 10-kilometer-wide asteroid hit the Gulf of Mexico 66 million years ago, it drove over 75% of Earth's species to extinction, including the dinosaurs.
