Hadrosaurus Foulkii Leidy Site

The Hadrosaurus Foulkii Leidy Site is an archaeological excavation area in Haddonfield where fossilized remains of an extinct dinosaur were uncovered in 1858. The land has been protected to preserve the historical find for ongoing research and study.

William Parker Foulke first excavated the fossilized bones, after which scientist Joseph Leidy conducted extensive analysis and explained their significance. This work laid the foundation for scientific understanding of dinosaurs in North America.

The discovery of this hadrosaur fundamentally changed how people viewed prehistoric creatures and sparked widespread public curiosity about dinosaurs. The event established paleontology as a subject that captures public attention.

The site is located along Maple Avenue in Haddonfield and marked with commemorative plaques and informational signs that make it easy to locate. It is readily accessible and provides space to walk around and explore the historical area.

The bones from here were later used to create the first mounted dinosaur skeleton for museum display, setting new standards for fossil presentation. This innovation changed how museums worldwide designed dinosaur exhibitions.
