Edelman Fossil Park
The Edelman Fossil Park & Museum, located in Mantua Township, New Jersey, features a 66-million-year-old 6-inch (150 mm) bone bed set into a 65-acre (26 ha) former marl quarry. It is currently the only facility east of the Mississippi River that has an active open quarry for public Community Dig Days. Formed at the end of the Cretaceous Period during the Cretaceous-Paleogene extinction event, this rich fossil deposit is abundant in marine life which is indicative of the shallow sea that once covered the area that would become Southern New Jersey. The palaeontological site has been developed into a park and museum with public programs, which opened on March 29, 2025. Named after donors Jean and Ric Edelman, it is owned and operated by Rowan University in Glassboro, New Jersey.
