A massive ice age wiped out ocean life 445 million years ago, reshaping ecosystems and setting the stage for jawed fish ...

Almost all life on land and in the ocean was wiped out during "The Great Dying," a mass extinction event at the end of the Permian Era about 250 million years ago. New evidence suggests that the Great ...

About 445 million years ago, Earth’s oceans turned into a danger zone. Glaciers spread across the supercontinent Gondwana, ...

Sharks might be the all time bullet-dodging champions. They’ve been around for about 450 million years, longer than trees, longer than the rings of Saturn, and longer than most of the other life on ...

Scientists Warn Earth Is Entering a Sixth Mass Extinction ...

One of Earth’s earliest mass extinctions wiped out most ocean life during a sudden global ice age. From the ruins, jawed vertebrates survived, diversified, and transformed the course of evolution.

A rapid climate collapse during the Late Ordovician Mass Extinction devastated ocean life and reshuffled Earth’s ecosystems.

During these waves of mass extinction, most vertebrate survivors were confined to refugia, or isolated biodiversity hotspots separated by large areas of deep ocean. In these zones, surviving jawed ...

The West Texas desert has a surprising feature: a prehistoric ocean reef. There is a surprising natural wonder in the middle of the vast West Texas desert: a prehistoric ocean reef built from the ...

Around 250 million years ago, one of Earth’s largest known volcanic events set off The Great Dying: the planet’s worst mass extinction event.... How did these species survive mass extinction events?

The collapse of tropical forests during Earth’s most catastrophic extinction event was the primary cause of the prolonged global warming which followed, according to new research. The Permian–Triassic ...
