1 janv. 470000000 av. J.-C. - Neugrund crater
Description:
Neugrund is a meteorite crater in Estonia. It is 8 km in diameter and was previously estimated to have been formed in the Ordovician around 470 Ma, with later research revealing a possible Cambrian origin. The crater is at the bottom of the sea and is not exposed at the surface. Boulders of gneissic breccia found on the coast of Osmussaar, a nearby island, are believed to have been thrown there by the explosion.
