In 1858, [[William Parker Foulke]] discovered the first known American dinosaur, in [[marl]] pits in the small town of [[Haddonfield, New Jersey]]. (Although fossils had been found before, their nature had not been correctly discerned.) The creature was named ''[[Hadrosaurus|Hadrosaurus foulkii]]''. It was an extremely important find: ''Hadrosaurus'' was one of the first nearly complete dinosaur skeletons found ([[Iguanodon#Gideon Mantell, Sir Richard Owen, and the discovery of dinosaurs|the first]] was in 1834, in [[Maidstone|Maidstone, England]]), and it was clearly a bipedal creature. This was a revolutionary discovery as, until that point, most scientists had believed dinosaurs walked on four feet, like other lizards. Foulke's discoveries sparked a wave of interests in dinosaurs in the United States, known as dinosaur mania.<ref name=weishampel06>{{cite journal |last1=Prieto-Marquez |first1=Albert |last2=Weishampel |first2=David B. |last3=Horner |first3=John R. |date=March 2006 |title=The dinosaur ''Hadrosaurus foulkii'', from the Campanian of the East Coast of North America, with a reevaluation of the genus |url=https://app.pan.pl/archive/published/app51/app51-077.pdf |url-status=live |journal=Acta Palaeontologica Polonica |location=Warsaw |publisher=Institute of Paleobiology, Polish Academy of Sciences |volume=51 |issue=1 |pages=77–98 |issn=0567-7920 |archive-url=https://web.archive.org/web/20190622113255/https://app.pan.pl/archive/published/app51/app51-077.pdf |archive-date=June 22, 2019 |access-date=November 5, 2019}}</ref>

Dinosaur mania was exemplified by the fierce rivalry between [[Edward Drinker Cope]] and [[Othniel Charles Marsh]], both of whom raced to be the first to find new dinosaurs in what came to be known as the [[Bone Wars]]. This fight between the two scientists lasted for over 30 years, ending in 1897 when Cope died after spending his entire fortune on the dinosaur hunt. Many valuable dinosaur specimens were damaged or destroyed due to the pair's rough methods: for example, their diggers often used [[dynamite]] to unearth bones. Modern paleontologists would find such methods crude and unacceptable, since blasting easily destroys fossil and stratigraphic evidence. Despite their unrefined methods, the contributions of Cope and Marsh to paleontology were vast: Marsh unearthed 86 new species of dinosaur and Cope discovered 56, a total of 142 new species. Cope's collection is now at the [[American Museum of Natural History]] in New York City, while Marsh's is at the [[Peabody Museum of Natural History]] at [[Yale University]].<ref name=Holmes/>
