The Neugrund meteor crater  in Estonia is a  8 km  diameter submarine  impact crater formed about 475 million years ago in the Ordovician period. The impact crater formed in a shallow epicontinental sea as the result of the impact of an extraterrestrial body with a diameter of about 400 m.
The location of the crater is  submerged, but  the nearby island of Osmussaar contain shock metamorphosed rocks and impact blanket debris  from the explosion. The structure  was only discovered in 1997.
