Another icon of natural history museums is the dinosaur skeleton. The first of these, the "Hadrosaurus" mount created by noted natural history artist Benjamin Waterhouse Hawkins, made its debut at the Academy in 1868. "Hadrosaurus" mounts also found their way into other public venues, including Princeton University, the Royal Scottish Museum, the Smithsonian, and the 1876 American Centennial Exposition. A special exhibit on the history of "Hadrosaurus foulkii" ran from November 22, 2008 to April 19, 2009.
