Learn how geological clues preserved in ancient oceans link repeated volcanic eruptions to Triassic marine extinctions.

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 ...

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 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 ...

It’s a warning flare for the present. By understanding what caused the ocean to acidify in the past, scientists hope to better predict and possibly prevent similar damage in the future. The story of ...

A geological field section reveals a desiccated (extreme dryness) land surface that was common all over the world 252 million years ago - a sign of our future to come. Mega ocean warming El Niño ...

The collapse of tropical forests during Earth’s most catastrophic extinction event was the primary cause of the prolonged global warming which followed, according to new research. The Permian–Triassic ...

The biggest mass extinction of all time happened 251 million years ago, at the Permian-Triassic boundary. Virtually all of life was wiped out, but the pattern of how life was killed off on land has ...

Russell has a PhD in the history of medicine, violence, and colonialism. His research has explored topics including ethics, science governance, and medical involvement in violent contexts. Russell has ...

Earth has a long and dramatic history, and one recurring theme is extinction. Did you know that over the last 500 million years, our planet experienced five major mass extinction events? These events ...
