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.
Popular theory suggests that a massive asteroid smashed into Earth around 65 million years ago wiping most life, including the dinosaurs, off the face of the earth. But scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event.
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.
A U.S. study suggests violent volcanic eruptions in India might have killed the dinosaurs 65 million years ago, not a meteor impact.
Earth history has been punctuated by several mass extinctions rapidly wiping out nearly all life forms on our planet. What causes these catastrophic events?
New discoveries about the timing and speed of gigantic, 6500-foot (2-km) thick lava flows that poured out of the ground 65 million years ago could shift the blame for killing the dinos.
The Columbia Plateau ecoregion is a Level III ecoregion designed by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington, with little areas over the Washington state border in Idaho. This ecoregion stretches across a wide swath of the Columbia River Basin from the Dalles, Oregon to Lewiston, Idaho to Okanogan, Washington near the Canadian border. It incorporates nearly 500 miles of the Columbia River, as well as the lower reaches of major tributaries....
