"New University of Oregon research has identified gravity-related fluctuations dating to 66 million years ago along deep ocean ridges that point to a "one-two punch" from the big meteor that struck off Mexico's Yucatan peninsula, possibly triggering a worldwide release of volcanic magma that could have helped seal the dinosaurs' fate. "We found evidence for a previously unknown period of globally heighted volcanic activity during the mass-extinction event," said former UO doctoral student Joseph Byrnes. The study by Byrnes and Leif Karlstrom, a professor in the UO's Department of Earth Sciences, was published Feb. 7 in Science Advances. It details a record of volcanism preserved along the mid-ocean ridges, which mark the oceanic boundaries of tectonic plates. The evidence comes from changes in the strength of gravity above the seaflor…"
