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 ...
Long before mammals dominated the land and even before the most famous dinosaurs appeared, Earth was home to a wide variety of powerful predators. While dinosaurs often get most of the attention when ...
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 ...
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 ...
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 ...
Everyone knows that dinosaurs are extinct, and most people have some idea about how it might have occurred. But the exact periods in history when it happened are less well known. Was it a single ...
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 ...
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 ...
