+ - Did Gas Kill Dinosaurs?

Ponca City, We Love You writes "Nature reports that volcanic eruptions from the Deccan Flood Basalts in India that released huge amounts of sulphur dioxide gas to the atmosphere may have had more to do with wiping out dinosaurs 65 million years ago than the meteorite strike at Chicxulub on Mexico's Yucatán Peninsula. Marine sediments reveal that Chicxulub hit Earth 300,000 years before the mass extinction while the Deccan volcanism released vast amounts of greenhouse gases into the atmosphere over a period of more than a million years raising worldwide temperatures. "On land it must have been 7-8 degrees warmer," says Princeton University paleontologist Gerta Keller. "The Chicxulub impact alone could not have caused the mass extinction, because this impact predates the mass extinction.""
