A new Triassic crocodylomorph from Gloucester sheds light on early crocodile evolution and pre-extinction ecosystems.

The mass extinction that wiped out nearly all life on Earth just before the dinosaurs evolved may have been caused by a global temperature drop rather than a rapidly warming climate. The End Triassic ...

Roughly 252 million years ago, Earth experienced its deadliest known extinction. Known as the Permian–Triassic Mass Extinction, or “The Great Dying,” this cataclysm wiped out over 80% of marine ...

Deposits in Morocco associated with the Triassic-Jurassic mass extinction, 201.6 million years ago. Red sediments in many locations around the world contain Triassic-era fossils. The white band on top ...

Our planet’s first known mass extinction happened about 440 million years ago. Species diversity on Earth had been increasing over a period of roughly 30 million years, but that would come to a halt ...

The Triassic-Jurassic Extinction, 201.6 million years ago, has been considered by some to have been a fairly slow-burn event, driven by rising temperatures and ocean acidification. A new study says it ...

“One of the great mysteries has been the survival and flourishing of a major group of amphibians called the temnospondyls,” Aamir Mehmood, a study co-author and evolutionary biologist at the ...

A new study has uncovered how strange amphibians that once lived in north-western Western Australia became early evolutionary success stories after the most catastrophic mass extinction in Earth’s ...

The mass extinction that ended the Permian geological epoch, 252 million years ago, wiped out most animals living on Earth. Huge volcanoes erupted, releasing 100,000 billion metric tons of carbon ...
