The earliest-known dinosaur fossils date to roughly 230 million years ago, including Eoraptor and Herrerasaurus from Argentina, Saturnalia from southern Brazil and Mbiresaurus from Zimbabwe.

The divergent patterns of Permian–Triassic mass extinction (PTME) have been extensively documented in varying water depth settings. We here investigated fossil assemblages and sedimentary microfacies ...

These ancient arthropods have survived multiple mass extinction events, including the famous Permian-Triassic extinction. Their unique and efficient physiology, including a hardy exoskeleton and a ...

But it wasn’t the only one! Actually, there have been many mass extinctions in the long history of our planet. Today we’re WONDERing about one of those: what was the Permian extinction? The Permian ...

Claudia Steffensen made a captivating discovery in the Italian Alps: a tropical ecosystem dating back 280 million years, made up of relics of the past such as plant fossils, raindrop tracks and ...

The mystery of dinosaur origins has taken an unexpected turn toward the equator. While paleontologists have long searched ...

By assessing the fossil record and the dinosaur family tree, the researchers’ models suggest that the first dinosaurs evolved ...

Because yes, birds are dinosaurs, she says. They were the only group of dinosaurs to survive the Cretaceous mass extinction around 65 million years ago (not to be confused with the Permian-Triassic ...

We hope to have demonstrated that trying to compare or equate the end-Permian marine invertebrate mass extinction in terms of taxonomic diversity dynamics with the Permo-Triassic plant biotic crisis ...

Dinosaurs evolved from more primitive reptiles in the aftermath of Earth's biggest mass-extinction event caused by extreme volcanism at the end of the Permian Period about 252 million years ago.
