Latest Extinction events Stories
Geologists from Trinity College Dublin have rewritten the evolutionary history books by finding that oxygen-producing life forms were present on Earth some 3 billion years ago – a full 60 million years earlier than previously thought.
After the asteroid impact at the end of the Cretaceous period that triggered the dinosaurs' extinction and ushered in the Paleocene, leaf-mining insects in the western United States completely disappeared.
A researcher from the Perth, Australia-based Curtin University has definitively shown how the first mass extinction event in the history of complex life was caused by ancient volcanic eruptions on his own continent some 510 million years ago
Plant and animal species are becoming extinct at rates more than 1,000 times more quickly than they did before the arrival of humans, indicating that the Earth could be edging closer to a sixth great extinction.
Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa.
252 million years ago the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water.
UC Riverside research team challenges conventional view of a simple two-step rise in early oxygen on Earth; study suggests instead dynamic oxygen concentrations that rose and fell over billions of years
A research team from MIT has determined that the end-Permian extinction took place over 60,000 years — give or take 48,000 years. From a geologic perspective, that's nearly instantaneous.
An asteroid or comet crashed into a shallow sea near what is now the Yucatan Peninsula of Mexico approximately 65 million years ago. A firestorm and global dust cloud resulted, causing the extinction of many land plants and large animals, including most of the dinosaurs.
At the end of the Permian period, approximately 250 million years ago, a mass extinction occurred that was so severe it remains the most traumatic known species die-off in Earth's history.
