Latest Permian–Triassic extinction event Stories
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.
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.
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.
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 demise of the worldâ€™s forests some 250 million years ago likely was accelerated by aggressive tree-killing fungi triggered by global climate change.
The release of a huge amount of methane gas may have caused a massive, prehistoric extinction that gave way to the arrival of dinosaurs as the dominant life form on earth, according to a new study.
A fossil unearthed in China in the 1970s turns out to have come from the crocodile family tree after it had already split from the bird family tree.
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.
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.
