In a marl pit on the John E. Hopkins farm in October 1858, William Parker Foulke unearthed the world’s first nearly complete dinosaur skeleton. The find was adjacent to this point, and it was also the first dinosaur skeleton ever mounted. The bones represented a 25 foot, 7-8 ton herbivorous hadrosaurus reptile, probably standing 6-10 feet high at the hips. Some 55 of an estimated 80 bones were discovered. This creature lived 70-80 million years ago during the Cretaceous Period at the end of the dinosaur age. This site was developed in 1984 as an Eagle Scout Project by Christopher Brees, Troop 65, with major project funding from the Academy of Natural Sciences, Philadelphia, Pa.
