Megaripples below Louisiana proof of tsunami caused by asteroid that killed dinosaurs

The video discusses the extinction of dinosaurs, highlighting the discovery of fossilized mega ripples caused by a massive tsunami 66 million years ago. This tsunami, triggered by an asteroid impact, devastated life across thousands of miles. While the immediate impact turned Earth into a fiery hellscape, the release of sulfur-bearing minerals led to global cooling, contributing to the extinction of 75% of species. The discovery of the largest ripples on Earth in Louisiana provides new insights into the aftermath of this catastrophic event.
