Leidy reconstructed "Hadrosaurus" as a biped, in contrast to the view at the time that such dinosaurs were quadrupedal. The entire skeleton was completely assembled in 1868 by a team including English sculptor and naturalist Benjamin Waterhouse Hawkins and was put on display at Philadelphia Academy of Natural Sciences. It was the first-ever mounted dinosaur skeleton. When the skeleton was first assembled, it was displayed with a plaster skull sculpted by Hawkins. Many other artists have recreated "Hadrosaurus" with skulls from other, related species such as "Gryposaurus" and "Brachylophosaurus". A statue of "Hadrosaurus", sculpted by Haddonfield resident John Giannotti, now stands in the center of the town of Haddonfield, commemorating its discovery there. "Hadrosaurus" was named the state fossil of New Jersey, designated in 1994. It is one of the most celebrated dinosaurs ever and is of great historic importance. The skeleton is usually kept 'behind-the-scenes' in the Academy's collections. However, from November 22, 2008, until April 19, 2009, a fully assembled cast of the skeleton and an exhibit about the science and culture surrounding the dinosaur's discovery was open to the public.
