New York Times : More than 50 000 meteorites have been found on Earth, but one is unique and belongs to a group of meteorites that haven’t fallen to Earth in 470 million years. The meteorite was found with more than 100 others collected from a limestone quarry in Sweden by Birger Schmitz of Lund University and his colleagues. It shared certain characteristics with the others in the collection that suggested it fell at the same time as they did, but it was otherwise distinct from all other known meteorites. Schmitz’s team believes the unique meteorite was once part of an asteroid that was destroyed in a collision with the asteroid that created the other meteorites they collected.
