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.
Map of ‘mega ripples’ created by dinosaur-killing asteroid uncovers secrets of ancient world
New details about the impact of the Chicxulub asteroid - the one which wiped out the dinosaurs - have been revealed after researchers created a new map of "mega ripples" on the seafloor. Around 66 million years ago (during the Cretaceous era),
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.
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,

Chicxulub: The asteroid that killed the dinosaurs
The Chicxulub impactor, as it is called, was somewhere between 10 and 15 kilometres in diameter. The collision was devastating: rocks from deep within Earth’s crust were raised 25 kilometres ...

How much damage could an asteroid cause?
An asteroid doesn't need to be massive to cause serious damage. The Chicxulub asteroid that wiped out the dinosaurs is estimated to have been about 6 miles in diameter. That may sound like a ...
