Smithsonian National Museum of Natural History Director Kirk Johnson, left, and Lt. Gen. Thomas Bostick, commanding general of the Army Corps of Engineers, unveil the fossilized bones of a Tyrannosaurus rex during a ceremony at the museum in Washington, Tuesday, April 15, 2014. The Tyrannosaurus rex is joining the dinosaur fossil collection on the National Mall on Tuesday after a more than 2,000-mile journey from Montana. For the first time since its dinosaur hall opened in 1911, the Smithsonian's National Museum of Natural History will have a nearly complete T. rex skeleton. FedEx is delivering the dinosaur bones in a truck carrying 16 carefully packed crates. (AP Photo/J. Scott Applewhite) less
