Brian Roemmele(@BrianRoemmele):Researchers at the University of Texas at Austin have determined that the 10-mile-wide subsurface Ames impact crater was formed during a meteor impact 100 million years later than previously believed, linking its formation to a violent extinction event that wiped out much of Earth’s marine life 372 million years ago.
