L-R: Kirk Johnson, Sant director of the Smithsonian National Museum of Natural History, poses with Montana ranchers Kathy and Tom Wankel, Lt. Gen. Thomas Bostick, commanding general and chief of engineers of the US Army Corps of Engineers and the fossilized right femur of a 65-million-year-old Tyrannosaurus Rex during a preview of the fossils at the museum on April 15, 2014 in Washington, DC. In 1988 the Wankels discovered the fossilized bones of a 65-million-year-old Tyrannosaurus Rex while hiking in a rugged section of a federal wildlife refuge in eastern Montana. 16 crates of the nearly-complete dinosaur fossil will be the centerpiece of the museum's new 31,000-square-foot fossil hall, which will open in 2019.
