Scientists in Scotland have established that the Nadir crater discovered at the bottom of the Atlantic Ocean in 2022 was left behind by a meteor that collided with the Earth alongside the dinosaur-slaying space rock that left behind a 200m crater in Mexico.

Dr. Uisdean Nicholson, leader of the research at Heriot-Watt University in Edinburgh, thinks that the asteroid would have crashed into the planet at a speed of 72,000km per hour and caused an 800m high tsunami across the ocean.

He said: "We originally thought that the asteroid would have been around 400m wide. We now think it was 450-500m wide, because of the larger crater size as shown by the 3D data.

"We can tell it came from about 20-40 degrees to the northeast, because of spiralling thrust-generated ridges surrounding the crater's central peak - those are only formed following a low-angle oblique impact.

"And we think it would have hit Earth at about 20km per second, or 72,000km per hour, although we still need to confirm this with a new set of impact models."
