Imagine a traveler from outer space, hurtling through the atmosphere of a bright, blue planet to land upon a world populated by strange, multi-tentacled creatures. It sounds like something from the pages of a science fiction novel, but it’s a true story and it’s written in stone. The stone is at Chicago’s Field Museum of Natural History, one of four unusual slabs in a recently opened display of meteorites.
At the time of the World’s Columbian Exposition in 1893, the collection of curiosities that would become the Field Museum included 170 meteorites. The museum now houses the Robert A. Pritzker Center for Meteoritics and Polar Studies, with a collection that includes more than 15,000 meteorites from over 1500 falls. “A fall,” explains Philipp Heck, associate curator of the Pritzker Center, “is an event in which the arrival of a meteorite is observed and recorded.” This allows fragments to be identified with that event. Meteorites not identified with a fall are known in the field of meteoritics as “finds.”
The museum has pieces of many famous meteorites.There’s a thousand-pound remnant of the Canyon Diablo meteorite that gouged the great meteor crater in the Arizona desert. There are fragments of the Chelyabinsk meteor, which made a fiery descent over Russia in 2014. There is even a meteorite that fell on a garage in Illinois in 1938, displayed alongside the holed seat and dented muffler of the car it struck. In a photograph taken shortly after the fall, the vehicle’s owner looks rather dismayed.
But possibly the most intriguing meteorites in the collection are four that are embedded in slabs of limestone. They are surrounded by a whitish discoloration of the rock, evidence of something leaching from them. These are fossil meteorites. One of them, our aforementioned celestial visitor, rests only inches away from the mineralized shell of a cephalopod, an extinct mollusk related to the modern nautilus. Fossils of prehistoric sea creatures are common in rocks dating from the Ordovician Period, which lasted from 500 to 435 million years ago. But fossil meteorites are rare. In fact, they were unknown until 1952, when the first find was made in Sweden. To date, only 115 have been found, almost all of them at a single quarry.
