The Barnum Museum mummy?s origins and authenticity were wrapped in mystery until Friday when two Quinnipiac University professors declared the mummy?s remains human.The professors spent a day pouring over the remains of a mummy called Pa-Ib, rumored to have been a 2,500-year-old Egyptian priest. The scientists found teeth, evidence of organs and other details that led them to declare the remains authentic.A museum staff member says this is the first round of the forensic investigation. On Thursday, scientists took x-rays and digital images and plan to do tissue analysis in a bid to determine Pa-Ib?s age at death, which region he lived in and whether he is actually a man or woman. The findings will be revealed in October at the Barnum Museum's gala event.Pa-Ib was a gift presented to the museum by PT Barnum?s second wife. The mummy has been in the collection for 114 years. Other museum curiosities include The Feejee Mermaid, a creature combining a monkey and fish, and a photo of Tiny Tim, his wife and their unborn child.
