At renovated Hall of Fossils, dinosaurs are just the start

The dinosaur bones at the Smithsonian Institution’s National Museum of Natural History now boast new accommodations. After a four-year, $125 million renovation, the Hall of Fossils now features state-of-the-art technology and new exhibits housing more than 700 specimens. As William Brangham reports, it also offers lessons about connecting the present to the past.
