Ever since the first dinosaur fossils were identified in the 19th century, scientists have been trying to figure out why ...

Deeper in time, a mass extinction event that ended the Devonian Period, a geological era when life thrived on land for the first time, was also attributed to a hyperthermal event likely triggered ...

Geobiologists shine new light on Earth's first known mass extinction event 550 million years ago Work shows a major loss of diversity during the Ediacaran Period, which lasted from 635 million to ...

This unprecedented die-off is now known as the earth’s first mass extinction, the Late Ordovician mass extinction or simply LOME. Many researchers have devoted time, or even careers, to uncovering the ...

Likewise, the Carnian pluvial episode, a smaller mass-extinction event that I’m also fond of and that occurred some 230 million years ago, was so pivotal that the scientists who study this ...

A mass extinction occurs when at least 75% of species are destroyed. The Earth has had five. The last one, about 65 million years ago, wiped out most dinosaurs.

A study of fossils from the Permian-Triassic extinction event 252 million years ago shows that forests in many parts of the ...

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, ...

Deeper in time, a mass extinction event that ended the Devonian Period, a geological era when life thrived on land for the first time, was also attributed to a hyperthermal event likely triggered ...

As climate change threatens tropical forests, a new study shows how the loss of those forests can be devastating to life on ...
