Answer 1

Answer

Geological evidence indicates that dinosaurs became extinct at the boundary between the Cretaceous and Paleogene eras, about 66 million years ago, at a time when there was worldwide environmental change resulting from the impact of a large celestial object with the Earth and/or from vast volcanic eruptions.

Answer 2

• For many years, paleontologists believed this event was caused by climate and geological changes that interrupted the dinosaurs' food supply. This suggests that a comet, asteroid or meteor impact event may have caused the extinction of the dinosaurs.
