Researchers led by Dr. Maura Brunetti at the University of Geneva studied fossilized plant remains, using spores, pollen, and macrofossils to reconstruct ancient ecosystems.

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

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.

The End-Permian mass extinction killed an estimated 80% of life on Earth, but new research suggests that plants might have done okay.

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 ...

An ancient mass extinction event left a long-hidden refuge, whose survivors repopulated the Earth much faster than previously believed.

Fossils before and after the end-Permian extinction “go from ... even those seen in the earliest Triassic, which has been the greatest homogenization event to date,” the study authors wrote.
