What it means

Scientists at the University of Texas at Austin have used of to determine that the in Oklahoma formed about 370 million years ago, not 470 million years ago as previously believed. This places the meteor impact in the period, roughly coinciding with a major mass extinction event, and challenges earlier age estimates based on less precise dating methods.

Accuracy & sourcesGrounded

The claim is solid, based on a peer-reviewed paper using uranium-lead dating of zircons, a well-established radiometric technique. The reporting in Science Daily is a direct press release from the University of Texas at Austin (the primary source), so it sits very close to the original research.
