Scientists found an undersea crater, operating 248 miles off the coast of West Africa. The massive undersea construction is believed to have been fashioned by an asteroid that slammed into the earth in the course of the age of dinosaurs. When the huge gap was fashioned beneath the earth, it might need modified the earth in some ways, together with a shift within the local weather.

Named the Nadir crater, its existence was found by mistake whereas scientists have been engaged on a distinct mission. Nonetheless, its discovery now modifications loads of data already identified in regards to the historical past of the earth.
The crater was first found by Uisdean Nicholson, an assistant professor on the Heriot-Watt College in Edinburgh. Whereas reviewing seismic survey information, he realized that there was a despair mendacity beneath 400 meters of seabed sediments.
“Whereas deciphering the information, I (got here) throughout this very uncommon crater-like characteristic, not like something I had ever seen earlier than,” he mentioned. “It had all of the traits of an impression crater.”
Whereas most scientists have confirmed that despair seems to be like a creator fashioned by an asteroid impression, additional research are vital. Consultants should drill to the underside of the crater and accumulate minerals on the backside for exams. This may be the one strategy to verify that it dates again to the mentioned time, a couple of 66 million years in the past.
“The chance to review an underwater impression crater of this dimension would assist us perceive the method of ocean impacts, that are the commonest however least nicely preserved or understood,” mentioned Mark Boslough, a researcher on the College of New Mexico.
