Asteroid, Louisiana and Megaripples

Discovery of Megaripples Beneath Louisiana’s Seafloor Reveals New Clues from Dinosaur-Killing Asteroid Impact
The incredible aftermath of the Chicxulub asteroid impact—one of the most cataclysmic events in Earth’s history—is unfolding beneath the seafloor of Louisiana. New research has uncovered massive “megaripples,
Extinction asteroid's impact on Earth laid bare as new map outlines 'mega ripples' on seafloor
Scientists have created a new 3D map of "mega ripples" on the seafloor caused by the Chicxulub asteroid impact that wiped out the dinosaurs. The study, published in the journal Marine Geology, reveals the forces generated by the space rock that triggered a global tsunami 66 million years ago.
52-foot-high 'megaripples' from asteroid that killed the dinosaurs mapped deep beneath Louisiana in 3D
Buried "megaripples" — some the size of five-story buildings — are helping scientists piece together the devastation following the impact that wiped out the nonavian dinosaurs.
Asteroid That Killed The Dinosaurs Left "Megaripple" Structure Underneath Louisiana
In 2021, a team led by Dr Gary Kinsland of the University of Louisiana at Lafayette found evidence that the impact and resulting tsunami left "megaripples" of sediment 16 meters (53 feet) high and 600 meters (1,969 feet) apart. These megaripples were deposits of sediment distributed in what was then the ocean floor, but now forms part of Louisiana.
