WASHINGTON, DC - APRIL 15: 3-D scanning specialist Jonathan Blundell uses a hand-held scanner while making images of the fossilized metatarsal of a 65-million-year-old Tyrannosaurus rex during a preview of the dinosaur fossils at the Smithsonian National Museum of Natural History April 15, 2014 in Washington, DC. Formerly known as the Wankel T. rex, the nearly-complete dinosaur fossil was discovered in 1988 in eastern Montana and will be the centerpiece of the museum's new 31,000-square-foot fossil hall, which will open in 2019.
