Dinosaurs

• Leidy collaborated with artist Benjamin Waterhouse Hawkins to mount Hadrosaurus foulkii for the Academy of Natural Sciences of Philadelphia. This became both the first mounted dinosaur skeleton ever mounted for public display and also one of the most popular exhibits in the history of the academy. Estimates have the Hadrosaurus exhibit as increasing the number of visitors by up to 50%.
