Wanted: Mysterious Natural Objects for Identification by Scientists
Field Museum scientists are ready to identify your strangest natural possessions this weekend.
“People often find natural history objects and wonder what they are,” said Bill Simpson, collections manager of fossil vertebrates at the Field Museum. “So we’ve invited the public to bring their natural history treasures in to us for identification.”
Visitors to the museum’s Identification Day on Saturday are encouraged to bring in fossils, seashells, leaves and photographs of mysterious animals for identification by experts from several different departments. (No living or dead animals, please–taxidermy excluded.)
“We’d like them to take pictures of those instead, but other than that, they can bring in just about anything,” Simpson said.
Several specimens and objects from the museum’s collections will be on display in the main lobby, where the event takes place. As the invertebrate fossil expert, Simpson said he plans to show off the jaws of a mastodon, a large, elephant-like mammal that became extinct roughly 10,000 years ago.
Over the past three years, Simpson has encountered some remarkable prehistoric objects at the event.
“I’ve had several people bring me Chinese dinosaur eggs,” Simpson said. “We’re happy to identify them, although we do advise them gently that those aren’t really legal to have in this country.”
After an object is examined, the owner will receive a certificate identifying it. Unless, of course, the experts are stumped.
Simpson said a positive identification hinges on several factors. Along with an item’s overall condition, there are certain “diagnostic features” that help him recognize fossils, for example.
“Mammals are often most easily identified if their molars are preserved,” Simpson said. “Mammal molars are very complicated and distinct to each different kind of mammal.”
Identification Day takes place Saturday from 10 a.m. to 2 p.m. in the Field Museum’s main hall – near SUE the T. rex. The event is free with admission.
Illinois residents with proof of residency, such as ID or utility bill, get free general admission on Saturday, Sunday and Monday, which includes access to general admission exhibits.
