Scientists discover a 5-mile wide undersea crater created as the dinosaurs disappeared
A space rock from space banged into the Earth's surface a long time back, leaving an enormous cavity under the ocean and unleashing destruction with the planet.
No, it isn't so much that space rock, the one that destined the dinosaurs to eradication, yet a formerly obscure hole 248 miles off the shore of West Africa that was made close to a similar time.
Further investigation of the Nadir hole, as it's called, could stir up what we are familiar that calamitous crossroads in normal history.
No, it’s not that asteroid, the one that doomed the dinosaurs to extinction, but a previously unknown crater 248 miles off the coast of West Africa
that was created right around the same time. Further study of the Nadir crater, as it’s called, could shake up what we know about that cataclysmic moment in natural history.
Uisdean Nicholson reviewing seismic survey data for another project on the tectonic split between South America and Africa and found evidence of the crater beneath 400 meters of seabed sediment.
To be sure beyond a shadow of a doubt the pit was brought about by a space rock strike, he said that it would be important to penetrate into the hole and test minerals from the cavity floor.
In any case, it has every one of the trademarks researchers would anticipate: the right proportion of hole width to profundity, the level of the edges, and the level of the focal elevate
- a hill in the middle made by rock and dregs constrained up by the shock pressure.
