Siberian Traps likely culprit for end-Permian extinction
New study finds massive eruptions likely triggered mass extinction.
What really killed the dinosaurs?
Before an asteroid wiped out the dinosaurs, Earth experienced a short burst of intense volcanism.
Ancient whodunit may be solved: The microbes did it!
Methane-producing microbes may be responsible for the largest mass extinction in Earth’s history.
An extinction in the blink of an eye
MIT researchers find that the end-Permian extinction happened in 60,000 years — much faster than earlier estimates.
A possible cause of the end-Permian mass extinction: Lemon juice?
MIT researchers find that rain as acidic as lemon juice may have contributed to massive die-offs on land 252 million years ago.
Huge and widespread volcanic eruptions triggered the end-Triassic extinction
Some 200 million years ago, an increase in atmospheric CO2 caused acidification of the oceans and global warming that killed off 76 percent of marine and terrestrial species on Earth.
An eruption-fueled extinction?
Enormous volcanic eruptions may have triggered the worst extinction in Earth’s history.
Timeline of a mass extinction
New evidence points to rapid collapse of Earth’s species 252 million years ago.
