Haddonfield, NJ

Haddonfield's best-known fossil is about 80 million years old: Hadrosaurus foulkii, then the most complete dinosaur skeleton known, was excavated in 1858 from the ravine now inside Pennypacker Park. The 32-acre county park follows the Cooper River and includes Hopkins and Driscoll ponds; a marker identifies the discovery site at a wooded street end. Downtown adds a different layer of history. New Jersey's legislature met at the Indian King Tavern in 1777 while organizing the new state government, and the state bought the building in 1903 as its first historic property. Interior and exterior restoration work was underway in 2026. Haddonfield counted 12,550 residents in 2020 and had an estimated 12,740 in July 2025. Kings Highway concentrates shops, public events, the tavern, and the library near Haddonfield's PATCO station.

The timetable effective in December 2025 gives the station direct rail service through Camden to Philadelphia stops at 8th and Market and along Locust Street, as well as east to Lindenwold. Haddonfield's 2026 calendar put reenactors, live music, and hands-on demonstrations in Kings Court on Saturdays from May through September; the library separately scheduled recurring adult and mystery book groups plus dinosaur-themed summer reading. From 2020 through 2024, 83 percent of homes were owner-occupied, the median owner-occupied value was $755,300, monthly costs for mortgage holders exceeded $4,000, and median gross rent was $1,897. Median household income was $200,400, and workers averaged 30 minutes of travel to work. The fossil site, state tavern, library programs, and commemorative events keep two very different eras present in ordinary community activity.
