When were the Last Dinosaurs on Earth?
Dinosaurs appeared somewhere between 243 and 231 million years ago. They became extinct around 66 million year ago, when the Cretaceous – Paleogene Extinction Event caused the extinction of 75% of all species on Earth. Dinosaurs were alive for between 177 and 165 years. We hope that you have found this page useful.
When did the asteroid kill the dinosaurs?
The asteroid that struck Earth about 66 million years ago and led to the mass extinction of dinosaurs may have hit one of the worst places possible as far as life on Earth was concerned. When it struck, the resulting cataclysm choked the atmosphere with sulphur, which blocked out the Sun.
