A timeline-driven account based on rock-core drilling and global sediment layers: the initial fireball, tsunami and shock ...

Earth, triggering one of the most devastating mass extinctions in history. In a single moment, life on the planet changed ...

Scientists have unearthed in Arizona fossils from an assemblage of animals, including North America's oldest-known flying reptile, that reveal a time of transition when venerable lineages that were ...

Imagine the sound of a dinosaur roaring... Super loud, right? Wrong... It turns out the giant prehistoric creatures almost certainly didn't roar. You might be surprised to hear that some scientists ...

The dinosaurs were not in decline before the asteroid hit, a new study finds. Instead, poor fossilization conditions and unexposed late Cretaceous rock layers mean they're either not preserved or ...

An analysis of North America’s fossil record for the 18 million years before dinosaurs disappeared suggests the prehistoric creatures’ extinction wasn’t inevitable.

A new study challenges the belief that dinosaurs were declining before the asteroid impact that ended their reign. Analysing 18 million years of fossil data, researchers argue that apparent drops ...

The end-Cretaceous extinction—the massive extinction event widely attributed to an asteroid impact that wiped out all non-avian dinosaurs approximately 66 million years ago—had a profound ...

This new map of the megaripples can help predict the impact of future tsunamis, and to better understand the dinosaur extinction event, scientists say.

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 ...
