Countless ancient species disappeared from the face of our planet after an asteroid hit it, causing massive climate disruption. But before that, many creatures were hit by a towering tsunami wave, destroying the modern-day American coast.

Researchers have discovered giant ripples underground in central Louisiana, suggesting an asteroid that caused the mass extinction of dinosaurs, triggered a massive tsunami too. According to the recent findings, the space rock, which is believed to have hit the Earth near the Yucatan Peninsula 66 million years ago, created a wave that may have been a mile high.

The scientists analysed a layer about 1,500 metres (just under a mile) beneath the ground and found well-preserved fossilised ripples spaced up to a half-mile apart. According to University of Louisiana geophysicist Gary Kinsland, the orientation of the mega-ripples aligned with the Chicxulub impact theory.

“The water was so deep that once the tsunami had quit, regular storm waves couldn’t disturb what was down there”, he noted.
