New dating has revealed that New Mexico's last dinosaurs were healthy, diverse and thriving at the end of the Cretaceous period, suggesting non-avian dinosaurs weren't in decline before being snuffed ...

Almost a hundred new animal species that survived a mass extinction event half a billion years ago have been discovered in a small quarry in China, scientists revealed Wednesday. The asteroid that ...

Previous studies have posited that the mass extinction that wiped the dinosaurs off the face of the Earth was caused by the release of large volumes of sulfur from rocks within the Chicxulub impact ...

Learn how the extinction of dinosaurs around 66 million years ago caused seeds to grow larger, filling in an important piece in the evolutionary history of fruit. The demise of dinosaurs around 66 ...

A meteorite hit Earth about 66 million years ago near what today is the Yucatán peninsula, causing widespread destruction and death. But almost simultaneously, intense volcanism covered a vast area of ...

Dinosaurs ruled the Earth for over 150 million years. Compared to the mere 4–6 million years that scientists believe humans and their earliest ancestors have been on the planet, it wouldn't be ...
