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 ...

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 ...

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

Mass extinction events throughout Earth’s history are characterized as significant disruptions to life on the planet. There ...
