Two enormous dinosaurs—Triceratops and Tyrannosaurus rex—reign over the National Museum of Natural History’s new exhibition, “The Last American Dinosaurs: Discovering a Lost World.” The show opens Nov. 25 and tells the story of non-avian dinosaurs’ final years in western North America through an extraordinary diversity of fossil animals and plants from the Hell Creek Formation in North Dakota, South Dakota and Montana.
