65 million years ago an asteroid hit the earth, causing the extinction of the dinosaurs along with three quarters of all species on earth at the time.

The crater where it hit was discovered on the Yucatan peninsula in 1978 during a geological survey for the Mexican state oil company Pemex. It was named Chicxulub.

Lucy Burns speaks to Glen Penfield, who first identified the crater, and Alan Hildebrand, whose research confirmed the discovery.
