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.

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,

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.
