In a catastrophic instant some 66 million years back, the span of life on the planet was forever changed. A six-mile-wide space rock slammed in to the coast of Mexicos Yucatn Peninsulaand it kicked off a worldwide cataclysm. The towering tsunamis that followed crashed on shores for a large number of miles. Wildfires raced across vast swaths of land. And the vaporization of rock across the seafloor unleashed gasses that sent the climate into wild swingsall which resulted in the extinction of some 75 percent of most species, including all non-avian dinosaurs.

But this may not function as whole story. Buried under layers of sand on the coast of West Africa are hints that the giant space rock might possibly not have been alone.

Researchers discovered a possible crater that spans some 5.3 miles wide, revealed in seismic surveys of the seafloor, in accordance with a fresh study published inScience Advances. The crater, dubbed Nadir following a submarine volcano nearby, has been carved by the impact of an area rock at the very least 25 % of a mile wideand it could have formed round the same time because the Chicxulub crater, the expansive scar in Earths surface from the dinosaur-killing asteroid.
