New insights into mass extinctions
Mass extinctions are known as times of global upheaval, causing rapid losses in biodiversity that wipe out entire animal groups. Some of the doomed...
Rise of marine predators reshaped ocean life as dramatically as mass...
Evolutionary arms races between marine animals overhauled ocean ecosystems on scales similar to the mass extinctions triggered by global disasters, a new study shows.

New placement for one of Earth’s largest mass extinction events
Curtin University research has shed new light on when one of the largest mass extinction events on Earth occurred, which gives new meaning to...
World’s greatest mass extinction triggered switch to warm-bloodedness
Mammals and birds today are warm-blooded, and this is often taken as the reason for their great success.
University of Bristol palaeontologist Professor Mike Benton,...
Discovery of a new mass extinction
It's not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record....
Fossil Pollen Record Suggests Vulnerability to Mass Extinction Ahead
Reduced resilience of plant biomes in North America could be setting the stage for the kind of mass extinctions not seen since the retreat...
Exploding stars may have caused mass extinction on Earth, study shows
Imagine reading by the light of an exploded star, brighter than a full moon -- it might be fun to think about, but this...
Asteroid, climate change not responsible for mass extinction 215 million years...
A team of University of Rhode Island scientists and statisticians conducted a sophisticated quantitative analysis of a mass extinction that occurred 215 million years...
In Earth’s largest extinction, land die-offs began long before ocean turnover
The mass extinction at the end of the Permian Period 252 million years ago—one of the great turnovers of life on Earth—appears to have...
One single primitive turtle resisted mass extinction in the northern hemisphere
Sixty-six million years ago, in the emerged lands of Laurasia—now the northern hemisphere—a primitive land tortoise, measuring about 60 cm, managed to survive the...
Mystery solved: Ocean acidity in the last mass extinction
A new study led by Yale University confirms a long-held theory about the last great mass extinction event in history and how it affected...
Ancient die-off greater than the dinosaur extinction
Clues from Canadian rocks formed billions of year ago reveal a previously unknown loss of life even greater than that of the mass extinction...
New evidence suggests volcanoes caused biggest mass extinction ever
Biggest Mass Extinction
Researchers say mercury buried in ancient rock provides the strongest evidence yet that volcanoes caused the biggest mass extinction in the history...
Evolution imposes ‘speed limit’ on recovery after mass extinctions
It takes at least 10 million years for life to fully recover after a mass extinction, a speed limit for the recovery of species...
In ancient oceans that resembled our own, oxygen loss triggered mass...
Roughly 430 million years ago, during the Earth's Silurian Period, global oceans were experiencing changes that would seem eerily familiar today. Melting polar ice...
Researchers uncover new clues to surviving extinction
Scientists are peeking into ancient oceans to unravel the complexities of mass extinctions, past and future. A new examination of Earth's largest extinction by...
Earth’s largest extinction event likely took plants first
Little life could endure the Earth-spanning cataclysm known as the Great Dying, but plants may have suffered its wrath long before many animal counterparts,...
Biggest mass extinction caused by global warming leaving ocean animals gasping...
This illustration shows the percentage of marine animals that went extinct at the end of the Permian era by latitude, from...
Human ancestors not to blame for ancient mammal extinctions in Africa
New research disputes a long-held view that our earliest tool-bearing ancestors contributed to the demise of large mammals in Africa over the last several...
Rare fossil bird deepens mystery of avian extinctions
During the late Cretaceous period, more than 65 million years ago, birds belonging to hundreds of different species flitted around the dinosaurs and through...
