Near Ellisdale in New Jersey's Crosswicks Creek valley, this unusually important paleontological locality has produced the largest and most diverse known fauna of Late Cretaceous terrestrial animals from eastern North America. Dating to the Campanian Stage about 75 to 76 million years ago, the site preserves a dense storm-created concentration of fossils from marine, estuarine, freshwater, and land habitats together, including sharks, fish, turtles, crocodilians, dinosaurs, amphibians, lizards, small mammals, plants, amber, and possible mangrove roots. Discovered in 1980, it has yielded more than 20,000 specimens and provides one of the clearest views of Appalachia's poorly documented eastern ecosystems.
