Earth’s Largest Extinction Event - Was It Caused By Siberian Volcanism?
2012-01-10 05:57:28

Around 250 million years ago, at the end of the Permian geologic period, there was a mass extinction so severe that it remains the most traumatic known species die-off in Earth´s history. Although the cause of this event is a mystery, it has been speculated that the eruption of a large swath of volcanic rock in Russia called the Siberian Traps was a trigger for the extinction. New research from Carnegie´s Linda Elkins-Tanton and her co-authors offers insight into how this volcanism...

New finding on mercury-volcanic link could re-write history on past annihilations Scientists have uncovered a lot about the Earth´s greatest extinction event that took place 250 million years ago when rapid climate change wiped out nearly all marine species and a majority of those on land. Now, they have discovered a new culprit likely involved in the annihilation: an influx of mercury into the eco-system. “No one had ever looked to see if mercury was a potential culprit....

Ancient Hyper-carnivore Species Survived For 35 Million Years

An ancient predator species with agile bodies, saw-like teeth and an insatiable appetite for meat survived a major extinction at a time when distant relatives of mammals ruled the Earth, according to new research by scientists at Cape Breton University and the University of Toronto Mississauga. In a study published in Naturwissenschaften — The Science of Nature, Professors Sean Modesto and Robert Reisz provided evidence that varanopids survived for more than 35 million years, and...

Image 1 - Researchers Pinpoint Date, Rate Of Earth's Most Extreme Extinction

Results stem from largest ever examination of fossil marine species 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. A team of researchers from North America and China have published a paper in Science this week which explicitly provides the date and rate of extinction. "This is the first paper to provide rates of such massive extinction," says Dr. Charles Henderson,...

Image 1 - Land Animals Suffered Catastrophic Losses After Permian Period
2011-10-26 06:31:51

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. As much as 90 percent of ocean organisms were extinguished, ushering in a new order of marine species, some of which we still see today. But while land dwellers certainly sustained major losses, the extent of extinction and the reshuffling afterward were less clear. In a paper published in the journal Proceedings of the Royal Society B,...
