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

A pair of 'Sacabambaspis' fish, around 14 inches (35 centimeters) in length, which had distinct, forward-facing eyes and an armored head. No fossils of animals like 'Sacabambaspis' from after the Late ...

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

Mass extinction events represent intervals of abrupt, large‐scale loss of biodiversity that have repeatedly reshaped life on Earth. These crises are commonly linked to dramatic environmental ...

About 445 million years ago, Earth nearly wiped out life in the oceans. Glaciers spread across the supercontinent Gondwana, ...

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

The term “mass extinction” conjures up apocalyptic images of the world coming to an end, but a massive event like this can be a much slower process than many people realize. By definition, a mass ...

Discover how the first mass extinction put jawed fishes on the map, species that would later come to dominate animal life on ...

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 new theory suggests depletion of trace elements in the oceans was a factor in three major mass extinction events in the past 600 million years, according to new research led by Flinders University's ...
