Latest Extinction events Stories
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 debate whether dinosaurs went extinct due to a large space rock that struck the Earth over 65 million years ago may have been answered with the discovery of a distinctive brow horn from a Ceratopsian dinosaur just 13 centimeters below the K-T boundary.
According to MIT researchers, new fossils suggest life had a rapid recovery after a global freeze.
The end-Permian extinction, by far the most dramatic biological crisis to affect life on Earth, may not have been as catastrophic for some creatures as previously thought.
The Chicxulub crater in Mexico, the site of the asteroid strike that brought the dinosaurs to extinction 65 million years ago, is among the highlights of ocean drilling projects proposed for the next decade.
Paleobiologists at the University of California at Berkeley are studying the state of biodiversity today using the worldâ€™s mammal species as a barometer.
With the steep decline in populations of many animal species, scientists have warned that Earth is on the brink of a mass extinction like those that have occurred just five times during the past 540 million years.
After a volcanic eruption that occurred around 250 million years ago almost 95 percent of all primitive life living in the ocean and 70 percent of all animals evolving on land were wiped out.
