Default New meteorite gives clues to origins of Earth impactors

"The space rock is a 470-million-year-old fossil meteorite first spotted
three years ago by workers at Sweden's Thorsberg quarry [...] its
texture and exposure age distinguish the new meteorite from the other
49,000 or so meteorites found so far on Earth."
