Summary:
- Researchers have discovered evidence of a large impact event that occurred during the Younger Dryas period, around 12,800 years ago, in Louisiana.
- The evidence includes a shallow crater, which is believed to have been caused by an airburst, or the explosion of a meteor or comet in the atmosphere.
- This impact event may have contributed to the climate changes and extinctions that occurred during the Younger Dryas period, a time of significant environmental and ecological upheaval.
