Latest Siberian Traps Stories
A research team from MIT has determined that the end-Permian extinction took place over 60,000 years — give or take 48,000 years. From a geologic perspective, that's nearly instantaneous.
At the end of the Permian period, approximately 250 million years ago, a mass extinction occurred that was so severe it remains the most traumatic known species die-off in Earth's history.
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.
Siberian traps and their relation to the mass extinction 250 million years ago.
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.
It was the greatest mass murder of all time - poison everywhere, billions slain - but the killers have never been positively identified.
Earth history has been punctuated by several mass extinctions rapidly wiping out nearly all life forms on our planet. What causes these catastrophic events?
