Asteroid, Dinosaur and Louisiana

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.
Scientists Found 52-Foot-Tall Underground Ripples From the Asteroid That Killed the Dinosaurs
The six-mile-wide asteroid punched a one-way ticket toward extinction for all non-avian dinosaurs. Some 66 million years after the Chicxulub asteroid impact kickstarted the Cretaceous–Paleogene (K-T) extinction, scientists are still finding stunning evidence of its destruction.
Asteroid That Killed The Dinosaurs Left "Megaripple" Structure Underneath Louisiana
Sixty-six million years ago, an asteroid thought to be around 12 kilometers (7.4 miles) in diameter impacted the Earth, forming a crater 200 kilometers (120 miles) in diameter, and 1 kilometer (0.62 miles) deep underneath what is now the Yucatán Peninsula in Mexico.
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,
New map of ‘mega ripples’ caused by dinosaur-killing asteroid helps recreate extinction event
Scientists have created a new map of "mega ripples" on the seafloor caused by the Chicxulub asteroid impact that wiped out the dinosaurs, revealing further the events that led to the devastating mass extinction event.
