ID Day 2023
September 9, 2023, 10:00 am - 2:00 pm
FreeFound a rock that looks like a dinosaur fossil? Snapped a photo of a bird you don’t recognize? Our scientists will examine your object and give you their best identification during our annual ID Day! Members of the public can bring in remnants of the natural world—including clean, dry bones, fossils, rocks, meteorites, seashells, artifacts, and photographs of mammals, birds, reptiles, fish, and insects—to be identified by the Field’s scientists.
Please leave anything that’s alive (or was recently) at home.
Nothing to bring in? We’ll have specimens from the museum’s collections on view.
Illinois residents enjoy free Basic admission on ID Day.
