Earth:Malingen Crater

From HandWiki

Malingen was confirmed as an impact crater in 2014. It is located near the city of Östersund in northern Sweden.[1] It is "probable" that it formed simultaneously with the nearby Lockne crater.[2][3] Computer simulations suggest the asteroid pieces that created the Lockne and Malingen craters were some 600 meters and 250 meters in diameter, respectively.[3] Malingen is 1 km in diameter and its age is estimated, using chitinozoan microfossils, which were also found in Lockne, to be 458 million years (Late Ordovician).
