Rare Fossil 'Mona Lisa' Meteorites May Be Evidence Of Ancient Cosmic Collision

They're being likened to the Mona Lisa -- four fossil meteorites that may be linked to an ancient cosmic crash in the early universe.

Dr. Philipp Heck, curator of meteorites and polar studies at the Field Museum in Chicago, made the comparison to the iconic Leonardo da Vinci portrait -- and not without reason.

“They are so rare and so unique,” he told the Chicago Sun-Times. “If people really saw the significance of these, they will stand out next to all these other 50,000 meteorites" -- the number of known meteorites around the world.

The golf ball-sized meteorites, which are set to go on display at the museum by year-end, are among only 100 such fossilized meteorites known to exist. They were recovered from a limestone quarry in southern Sweden.

The first fossil meteorite ever discovered was found in Sweden in 1952, and it took almost 30 years before it was identified as a meteorite.

According to Heck, researchers have only just now scratched the surface of determining the origin of the meteorites. So far, they think the meteorites may have fallen to Earth almost 500 million years ago as the remnants of a giant asteroid collision.
