THIS IS OUR BELOVED HADDY AT CHRISTMAS.
In 1838, John Estaugh Hopkins was digging in a marl pit (on a small tributary of the Cooper River in Haddonfield, New Jersey, and part of the Campanian-age Woodbury Formation) when he uncovered large bones, putting them on display at his home, also in Haddonfield. In 1858, these bones sparked the interest of a visitor, William Parker Foulke. The skeleton was dug out from the marl pit in 1858 by Foulke. The excavation site, known as the Hadrosaurus foulkii Leidy site, is now a National Historic Landmark. Foulke contacted paleontologist Joseph Leidy, and together they recovered an almost complete set of limbs, along with a pelvis, several parts of the feet, 28 vertebrae (including 18 from the tail), eight teeth and two small parts of the jaw. Foulke and Leidy studied the fossils together, and in 1858, Leidy formally described and named Hadrosaurus foulkii in honor of his collaborator.[
