     Oklahoma’s Ames crater may be 100 million years younger than thought

     In a groundbreaking discovery, researchers have re-dated the Ames impact structure to approximately 370 million years ago, bringing it in line with a notable extinction event in Earth's geology. Initial dating based on fossil records suggested an earlier timeframe, but through enhanced zircon crystal dating techniques, scientists found a more accurate estimate that may transform our understanding of historical meteor impacts across North America.

     Oklahoma meteor crater found to be nearly 100 million years younger

     Researchers from the University of Texas at Austin have traced the Ames meteor impact to approximately 370 million years ago, presenting a significant revision to the previously accepted estimate of 467 million years. This research connects the impact with the Frasnian-Famennian mass extinction event, employing zircon crystals to establish a more precise timeline, thus providing deeper insights into pivotal moments in Earth's geological history.
