Wurden die Dinosaurier von zwei Asterioden ausgelöscht?

By Ninian Carter

August 18, 2022 - Ein kürzilich entdeckter Untersee Krater vor der Küste von Westafrika führt Wissenchafter zur Frage, ob Dinosaurier von mehr als einem Asteroid vor 66 Millionen Jahren ausgelöscht wurden?

What appears to be a second large asteroid impact crater has been discovered under the sea off the coast of West Africa, leading scientists to speculate that it may have been the smaller cousin of the one that struck the gulf of Mexico millions of years ago, wiping out the dinosaurs.

At 9km wide, the newly discovered crater – dubbed the Nadir Crater – is not as larger as the vast Chicxulub Crater in Mexico, which is estimated to be around 180km wide and 20km deep.

However, its size, age and placement on the other side of the Atlantic Ocean is leading geoscientists to wonder if the Earth was hit by more than one space rock that fateful day 66 million years ago, or if the Nadir asteroid was a chunk that broke off the Chicxulub asteroid.
