Researchers at the Carnegie Museum of Natural History found a human skull in an exhibit that was moved for restoration. Investigators originally thought the man featured in the display was a mannequin with human teeth. Researchers can't return the skull to its tomb because its origin is still a mystery, according to The Tribune Review. It then moved to New York's Museum of Natural History, and now rests at the Carnegie Museum of Natural History. Museum researchers and their partners are now working on a multi-part series explaining how the new discoveries add to the museum's understanding of the depicted era.
