By simulating the movement of two continent-sized Big Lower-Mantle Basal Structures, or BLOBs, researchers may have uncovered the magmatic engine behind Earth’s most devastating eruptions.

The Triassic-Jurassic extinction was not as rapid or violent in its consequences as the asteroid impact of 66 million years ago. So far as paleontologists have been able to reconstruct the ancient ...

Researchers report three distinct tanystropheid taxa from the upper Blue Mesa Member of the Chinle Formation in the Petrified ...

The End Triassic Extinction, which occurred about 201.6 million years ago, stamped out three-quarters of all life on Earth, and has long been thought to be linked to the volcanic eruption of the ...

Less clear is what drove the extinctions on land. Until the end-Triassic extinction, relatives of today’s crocodiles dominated land ecosystems, while early dinosaurs were relatively minor players.

Positioned between the worst mass extinction of all time and the one that finished off the dinosaurs, the Triassic extinction is, understandably, less notorious. But in its own way, it was just as ...

During the Triassic period nearly 250 million years ago, a small reptile scurried after insects in the canopy of a lush forest. The creature, which could fit snugly inside the palm of a hand, looked ...

Pulses of volcanic eruptions during a mass extinction event 200 million years ago produced the same amount of carbon dioxide as is predicted to be emitted over the 21st century, a study has found ...

The Permian-Triassic die-off dwarfed the extinction event that killed off the dinosaurs almost 190 million years later. About 70 percent of land-based species became extinct, but the toll was even ...

It made room for dinosaurs and mammals In a very literal way, you have the Permian-Triassic extinction (and all other catastrophic moments of the planet’s history) to thank for your very existence.

Researchers have long cited intense volcanism in modern-day Siberia as the main culprit behind the cataclysm, also known as the Permian-Triassic mass extinction, 252 million years ago.
