Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams.

A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition now known as the Bone Wars. In the late 19th century, paleontologists Edward Cope and O.C. Marsh uncovered the remains of hundreds of prehistoric animals in the American West, including dozens of previously undiscovered dinosaur species. But the rivalry that developed between them would spiral out of control, permanently damaging their careers and threatening the future of American paleontology.
Though Cope's scientific pursuits nearly bankrupted him, his contributions helped to define the field of American paleontology.
