Latest Extinction events Stories
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.
The cataclysmic events that marked the end of the Permian Period some 252 million years ago were a watershed moment in the history of life on Earth.
Seeking to better understand the level of death and destruction that would result from a large meteorite striking the Earth, Princeton University researchers have developed a new model that can not only more accurately simulate the seismic fallout of such an impact, but also help reveal new information about the surface and interior of planets based on past collisions.
University of Colorado researchers have found that worms were among the first animals to surface after an asteroid plowed into the Gulf of Mexico 65.5 million years ago.
Earth's largest mass extinction event, the end-Permian mass extinction, occurred some 252 million years ago. An estimated 90 percent of Earth's marine life was eradicated.
While the cause of the mass extinction that occurred between the Permian and Triassic periods is still uncertain, two University of Rhode Island researchers collected data that show that terrestrial biodiversity recovered much faster than previously thought, potentially contradicting several theories for the cause of the extinction.
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
