University of Washington paleontologist Christian Sidor smiles as he talks about a fossilized mammoth tusk, lower left, partially wrapped in layers of foil, plaster and plastic to allow it to slowly dry at the school's Burke Museum Wednesday, Feb. 26, 2014, in Seattle. Museum officials say the tusk, found at a construction site in downtown Seattle, will reveal its age, gender and life story as soon as scientists can stabilize the fossil by drying it out slowly over the next year.
