The Hadrosaurus Foulkii Leidy Site in Haddonfield, NJ is a historic paleontological site where the first relatively complete set of dinosaur bones was discovered in 1838 and fully excavated in 1858 by William Parker Foulke. Designated a National Historic Landmark in 1994, the site is now a small park known as Hadrosaurus Park, showcasing the remains of the Hadrosaurus foulkii dinosaur. Visitors can explore the Marl pit where the bones were found and learn about the excavation process that led to the discovery of this herbivorous dinosaur that lived 73 million years ago during the Cretaceous period. The site gained renewed attention in 1984 when a local Boy Scout's project led to the Hadrosaurus being designated as the official dinosaur of New Jersey.Generated from the website
