Mass extinction
Study shows the evolution of biomass over 500 million years
This is the first study to calculate long-term trends in the total abundance of life.
Mammals were living on the ground several million years before the mass extinction
Many mammals were already shifting toward a more ground-based lifestyle.
How Ancient Amphibians Survived Earth’s Deadliest Mass Extinction
Amphibians bounce-back from Earth’s greatest mass extinction.
Some sea life could face extinction over the next century
Pioneering research shows sea life will struggle to survive future global warming.
Ecuadorean cloud forest’s recent mass extinction found to be a mirage
Many of Centinela's plants are still on the brink of extinction.
Rapid evolution of bird genomes is linked to end-Cretaceous mass extinction
Life for non-avian dinosaurs ended, but the evolutionary story for the early ancestors of birds began.
Human hunting played a decisive role in the extinction of large mammals
Humans were responsible for the extinction of large mammals.
Scientists built the most extensive and most detailed bird family tree to date
Computational tools fuel reconstruction of new and improved bird family tree.
Dinosaurs’ range of locomotion made them incredibly adaptable; study
Dinosaurs’ success helped by specialized stance and gait.
Exploring shell life species after Earth’s largest extinction
Shell life species not competitors as they adjusted to Earth’s largest extinction.
Fossil discovery of a saber-toothed creature connects northern and southern hemisphere faunas
New top predator in town (at least, temporarily).
Biodiversity loss caused ecological collapse after the “Great Dying”
Biodiversity loss could lead to ecological collapse.
Patterns of mass extinction coincided with rapid decrease in marine oxygen levels
This evidence has important implications for modern deoxygenation and biodiversity declines.
Evolution of tree roots may have driven mass extinctions
Geologists find link between ancient, global-scale extinction events and modern threats to Earth’s oceans.
Dinosaurs killing impact triggered a “mega-earthquake” that lasted weeks to months
The amount of energy released in this "mega-earthquake" is estimated at 1023 joules
Most mass extinctions occurred after mega-eruptions
The impact of repeated eruptions over millennia.
Climate cooling contributed to sulphurous end for the dinosaurs
The gases were ejected into the Earth’s atmosphere after a six-mile-wide asteroid slammed into the planet.
Low volcanic temperatures led to the fourth mass extinction
Low volcanic temperature ushered in global cooling and the thriving of dinosaurs.
Rock samples record the first day the dinosaurs wiped out
That’s the scenario scientists have hypothesized.
Dinosaurs were thriving before asteroid strike that wiped them out
Scientists believe that an asteroid impact, potentially combined with serious volcanic movement, wiped out the dinosaurs at the end of the Cretaceous period. Although,...
![This illustration shows the percentage of marine animals that went extinct at the end of the Permian era by latitude, from the model (black line) and from the fossil record (blue dots). A greater percentage of marine animals survived in the tropics than at the poles. The color of the water shows the temperature change, with red being most severe warming and yellow less warming. At the top is the supercontinent Pangaea, with massive volcanic eruptions emitting carbon dioxide. The images below the line represent some of the 96 percent of marine species that died during the event.

Global warming wiped out 95% of marine life 252 million years ago
A new study by the University of Washington has suggested that extreme global warming caused Earth's biggest-ever mass extinction. The largest extinction in Earth's history marked...
