Scientists reported on Thursday that they believe a series of volcanic eruptions in modern day India may have been the cause of mass extinctions of species including dinosaurs over the last 545 million years.

The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago.
