Latest Extinction events Stories
Sixty-five million years ago, the most studied mass extinction in Earth's history happened and the dinosaurs were wiped off the planet, but a new study indicates that a separate extinction came shortly before that.
Asteroid impact craters are found all over the Earth, but most are erased by erosion or covered by time. The date has moved a billion years back by the discovery of the oldest impact crater yet at 3 billion years old.
A basic tenet underpinning scientists' understanding of extinction is that more abundant species persist longer than their less abundant counterparts, but a new University of Georgia study reveals a much more complex relationship.
An asteroid impact may have ended the reign of the dinosaurs here on Earth about 65 million years ago, but new evidence suggests many of the large, plant-eating dinosaurs were already dying out during the last 12 million years of the Cretaceous period.
In a first of its kind study, researchers from Vanderbilt University found that mammals’ best defense to adapting to climate change was diversity, and families with higher taxonomic diversity were better able to survive ongoing environmental changes.
The second-largest mass extinction in Earth's history coincided with a short but intense ice age during which enormous glaciers grew and sea levels dropped.
A 16-member international team of researchers that includes James Kennett, professor of earth science at UC Santa Barbara, has identified a nearly 13,000-year-old layer of thin, dark sediment buried in the floor of Lake Cuitzeo in central Mexico.
Around 250 million years ago, most life on Earth was wiped out in an extinction known as the “Great Dying.” A team led by University of Cincinnati geologist Thomas J. Algeo finds that the end came slowly from thousands of centuries of volcanic activity.
It's well known that Earth's most severe mass extinction occurred about 250 million years ago. What's not well known is the specific time when the extinctions occurred....until now.
A cosmic one-two punch of colossal volcanic eruptions and meteorite strikes likely caused the mass-extinction event at the end of the Cretaceous period that is famous for killing the dinosaurs 65 million years ago.
