For decades, scientists have conducted research centered around the five major mass extinctions that have shaped the world we live in. The extinctions date back more than 450 million years with the Late Ordovician Mass Extinction ...
Understanding Earth's species and ecosystems is a monumentally challenging scientific pursuit. But with the planet in the grip of its sixth mass extinction event, it has never been a more pressing priority.
The late Devonian extinction, about 370 million years ago, is one of the 'Big Five.' It killed up to 80 percent of species, obliterating the lavish Devonian coral reef ecosystem. The final pulse in this multi-step crisis, ...
Around 260 million years, the Earth was dominated by mammal like reptiles called therapsids. The largest of these therapsids were the dinocephalians, a genus composed of several herbivorous and carnivorous species.
A team of researchers is using network analysis techniques - popularized through social media applications - to find patterns in Earth's natural history, as detailed in a paper published today in the Proceedings of the National ...
Why do our oceans contain such a staggering diversity of fish of so many different sizes, shapes and colors? A UCLA-led team of biologists reports that the answer dates back 66 million years, when a six-mile-wide asteroid ...
About 252 million years ago, more than 90 percent of all animal life on Earth went extinct. This event, called the "Permian-Triassic mass extinction," represents the greatest catastrophe in the history of life on Earth. Ecosystems ...
It is commonly understood that the dinosaurs disappeared with a bang – wiped out by a great meteorite impact on the Earth 66 million years ago.
Mass extinctions throughout the history of the Earth have been well documented. Scientists believe that such extinctions occurred during a short period of time in geological terms. In a new study, palaeobiologists at Friedrich-Alexander-Universität ...
After a great mass extinction shook the world about 252 million years ago, animal life outside of the ocean began to take hold. The earliest mammals entered the scene, and reptiles—including early dinosaurs—lived on Pangea, ...
