Stegosaurus from NY World's Fair
Jensen, Utah
At 25 feet long, the plate-backed Stegosaurus is sculpted life-size from fiberglass by Hungarian artist Louis Paul Jonas. It was originally part of the "Sinclair Dinoland" exhibit at the 1964-65 New York World's Fair. It's stood in various spots at Dinosaur National Monument since 1970, when Sinclair deliberately dispersed its nine dinos to parks and museums throughout the country after they were rejected by the snobby Smithsonian. Unique among its fellow thunder lizards, the Stegosaurus has a twin, "Wally," in Massachusetts.
