On Saturday, May 11, scientists will attempt to identify your discoveries while showing you some specimens from their own collections.

Each year, people bring their shells, rocks, insects, feathers, bones, and artifacts to the Museum’s annual Identification Day. On Saturday, June 16, scientists will attempt to identify your discoveries while showing you some specimens from their own collections. Items identified in previous years have included a whale jawbone, a green beetle bracelet from Brazil, and a 5,000-year-old stone spear point from Morocco. Watch the video below for some pointers on what to bring.

You can now explore some of the objects identified at this year’s ID Day—including a 100-million-year-old fossilized fish and a French Navaja knife—online in the AMNH ID Day group on Flickr. You are also invited to add your own specimen photos, comments, and stories to the group. Sharing your photos is easy: just join the AMNH ID Day group and add your photos to the pool. Unidentified objects are welcome—your photo might be selected for identification by a Museum scientist in the coming months!
