Wired News reports on the American Museum of Natural History's ID Day, sort of an antiques roadshow of biology and anthropology where the public can have scientific "treasures" appraised.
"Previous Identification Day examinations have yielded a fossilized whale's jawbone, a rare green beetle bracelet from Brazil and a 5,000-year-old stone spear point. But most often the items are identified as tourist trinkets or valueless bits and pieces of bone and stone."
