The world's oldest crater from a meteorite isn't an impact crater after all

A team led by Chris Yakymchuk at the University of Waterloo found that a three-billion-year-old crater in Greenland is inconsistent with an impact crater, but instead formed through normal geological processes. The discovery was made after a 40-million-year delay from the initial proposed meteorite impact date.
