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 ...

The Triassic–Jurassic transition represents one of Earth’s most profound episodes of biological upheaval, characterised by extensive volcanic activity, rapid climatic shifts and cascading ...

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 ...

A new study reveals that Earth's biomes changed dramatically in the wake of mass volcanic eruptions 252 million years ago. Reading time 3 minutes 252 million years ago, volcanic eruptions in ...

The fossils were uncovered at a remote bonebed in present-day Arizona’s Petrified Forest National Park. They date back to the late Triassic period and offer paleontologists a snapshot of an ecosystem ...

Ancient frog relatives survived the aftermath of the largest mass extinction of species by feeding on freshwater prey that evaded terrestrial predators, University of Bristol academics have found. In ...

In a groundbreaking study, new fossil evidence has shed light on the mysterious 5-million-year heatwave that followed Earth’s most catastrophic extinction event—known as the Permian-Triassic Mass ...
