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

Our planet’s first known mass extinction happened about 440 million years ago. Species diversity on Earth had been increasing ...

The Permian extinction reminds him of Agatha ... Lystrosaurus, the synapsid that inherited the barren world of the Triassic, stared out empty-eyed. With its competition gone, Lystrosaurus spread ...

The Permian-Triassic extinction, also known as the Great Dying, was the most devastating event in Earth’s history. 96% of marine life and 70% of terrestrial vertebrates vanished around 252 ...

If this increase continues at the same rate, we will reach the level of emissions that caused the Permian-Triassic mass extinction in around 2,700 years—a much faster timescale than the Permian ...

After Earth's worst mass extinction, surviving ocean animals spread worldwide. Stanford's model shows why this happened.

If this increase continues at the same rate, we will reach the level of emissions that caused the Permian-Triassic mass extinction in around 2,700 years — a much faster timescale than the ...

However, the Cretaceous–Paleogene extinction event was not the worst loss of life in our planet’s history. That distinction belongs to the Permian-Triassic extinction or the Great Dying.
