The eruption occurred at the same time and had the same origin as lava flows found in North America, Africa and Europe, said Paul Renne of the University of California at Berkeley, who led the international team that conducted the research.

And, he added, an early mass extinction at the same time seems likely to have been connected to the huge magma flow.

The eruption, which occurred over a few million years, tore apart the ancient continent of Pangea, opening up what is now the Atlantic Ocean, the scientists reported. …
