Meteorite Carved Huge Greenland Crater 58 Million Years Ago, Study Says

A huge crater in northwest Greenland, buried under a thick layer of ice and first spotted in 2015, is much older than previously suspected – formed by a meteorite impact 58 million years ago years, instead of 13,000 years as had been proposed.

They found the meteorite – around 1.5-2km across – hit Greenland around 8 million years after a larger asteroid impact on Mexico’s Yucatan Peninsula wiped out the dinosaurs .
