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 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 ...

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 ...

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 ...

The idea that extreme climate change could one day cause a mass extinction and end the human dominance is not as farfetched as it may seem.

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 ...

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 ...

Approximately 250 million years ago, during the Permian-Triassic extinction event, which is also popularly known as the period of "The Great Dying", the Earth experienced its most catastrophic ...

A new study reveals that Earth's biomes changed dramatically in the wake of mass volcanic eruptions 252 million years ago. Reading time 3 minutes 252 million years ago, volcanic eruptions in ...
