The annual ID Day at the Ruthven Museums Building drew over 725 citizen scientists of all ages on Sunday, Oct. 4, 2015.

To all of the volunteers, Kira Berman, director of education for the University of Michigan Museum of Natural History said, “You helped the public understand the science and research that goes on here, and encouraged public enthusiasm and interest. We received many compliments on your expertise, patience, and the wonderful objects you brought to show the public.”

A smattering of the many dozens of mystery items that were brought to the event for identification included treasures as diverse as: skulls of a red fox and a raccoon, nanny berry and black cherry, reptile and mammal teeth, a wooly brown bear caterpillar and a blister beetle, pudding stone and petrified wood, a wooly gall wasp, a fossil clam and a fossil brachiopod and a full-grooved axe from southeast Michigan (6000-1000 BCE). A local physician and former docent attended the event and donated a crate of Green River formation fish fossils.
