Lockne crater
Template:Short description Template:Infobox terrestrial impact site Lockne is a meteorite crater, located approximately Script error: No such module "convert". south of the city of Östersund in northern Sweden.[1] It has been suggested that it is a doublet with the nearby smaller Målingen Crater, Script error: No such module "convert". apart.[2] Computer simulations suggest that the asteroid that created the Lockne crater was some Script error: No such module "convert". in diameter, and the one that carved out Målingen crater was about Script error: No such module "convert". across.[2]
It is Script error: No such module "convert". in diameter and the age is estimated, based on accompanying chitinozoan microfossils, to be 458 million years (Late Ordovician).[1] The crater is exposed at the surface. Its fossils, typical of shallow marine environments, show it to be a marine target impact event.
