The narrative of life on Earth is marked by a continual ebb and flow, characterized by the emergence and extinction of ...

The Cretaceous-Paleogene mass extinction, occurring approximately 66 million years ago, represents one of the most dramatic biotic crises in Earth’s history.

The mass extinction at the end of the Cretaceous Period is perhaps the most famous in history. Over 66 million years ago, a 15-kilometer-wide asteroid struck what is now Mexico and changed life on ...

That said, there is evidence of two minor mass-extinctions during the middle Cretaceous. One of them resulted in the extinction of the ichthyosaurs. Cretaceous-Paleogene (K-Pg) Extinction Event ...

Marine bivalves lost around three-quarters of their species during this mass extinction, which marked the end of the Cretaceous Period. My colleagues and I – each of us paleobiologists studying ...

Around 66 million years ago, Earth endured a mass extinction event that marked the end of the Cretaceous and the start of the Paleogene period. Roughly 75% of all species vanished, including every ...

By the end-Cretaceous mass extinction event - punctuated by the meteor that killed the non-avian dinosaurs - most of the survivors are semiaquatic generalists and a group of aquatic carnivores.

Jablonski explained that many scientists assumed that if you flatten the playing field, as in a mass extinction, the survivors should all take advantage of the opportunity and diversify rapidly. “That ...
