52-foot-tall ‘megaripples’ from dinosaur-killing asteroid are hiding under Louisiana

Ancient “megaripples” as tall as five-story buildings are hiding deep under Louisiana, and their unique geology indicates that they formed in the immediate aftermath of the asteroid strike that killed the nonavian dinosaurs, a new study finds. The 52-foot-tall (16 meters) megaripples are about 5,000 feet (1,500 m) under the Iatt Lake area, in north central Louisiana, and date to the end of the Cretaceous period 66 million years ago, when that part of the state was underwater, the researchers said. The megaripples’ size and orientation suggest that they formed…
