The "Bone Wars": Marsh vs Cope

The Bone Wars, also known as the "Great Dinosaur Rush", was a period of intense and ruthlessly competitive fossil hunting and discovery during the Gilded Age of American history, marked by a heated rivalry between Edward Drinker Cope (of the Academy of Natural Sciences in Philadelphia) and Othniel Charles Marsh (of the Peabody Museum of Natural History at Yale). Each of the two paleontologists used underhanded methods to try to outdo the other in the field, resorting to bribery, theft, and destruction of bones. Each scientist also sought to ruin his rival's reputation and cut off his funding using attacks in scientific publications.

Their search for fossils led them west to rich bone beds in Colorado, Nebraska, and Wyoming. From 1877 to 1892, both paleontologists used their wealth and influence to finance their own expeditions and to procure services and dinosaur bones from fossil hunters. By the end of the Bone Wars, both men had exhausted their funds in the pursuit of paleontological supremacy.

Cope and Marsh were financially and socially ruined by their attempts to outcompete and disgrace each other, but their contributions to science and the field of paleontology were massive, and provided substantial material for further work—both scientists left behind many unopened boxes of fossils after their deaths. The efforts of the two men led to over 136 new species of dinosaurs being discovered and described. The products of the Bone Wars resulted in an increase in knowledge of prehistoric life, and sparked the public's interest in dinosaurs, leading to continued fossil excavation in North America in the decades to follow. Several historical books and fictional adaptations have been published about this period of intense fossil-hunting activity.

Background

At one time, Cope and Marsh were amicable. They met in Berlin in 1864 and spent several days together. They even named species after each other. Over time their relations soured due in part to their strong personalities. Cope was known to be pugnacious and possessed a quick temper; Marsh was slower, more methodical, and introverted. Both were quarrelsome and distrustful. Their differences also extended into the scientific realm as Cope was a firm supporter of Neo-Lamarckism while Marsh supported Charles Darwin's theory of evolution by natural selection. Even at the best of times both men were inclined to look down on each other subtly. As one observer put it, "The patrician Edward may have considered Marsh not quite a gentleman. The academic Othniel probably regarded Cope as not quite a professional."

Cope and Marsh came from very different backgrounds. Cope was born into a wealthy and influential Quaker family based in Philadelphia. Although his father wanted his son to work as a farmer, Cope distinguished himself as a naturalist. In 1864, already a member of the Academy of Natural Sciences, Cope became a professor of zoology at Haverford College and joined Ferdinand Hayden on his expeditions west. In contrast, Marsh would have grown up poor, the son of a struggling family in Lockport, New York, had it not been for the benefaction of his uncle, philanthropist George Peabody. Marsh persuaded his uncle to build the Peabody Museum of Natural History, placing Marsh as head of the museum. Combined with the inheritance he received from Peabody upon his death in 1869, Marsh was financially comfortable (although, partly because of Peabody's stern views on marriage, Marsh would remain a lifelong bachelor).

On one occasion, the two scientists had gone on a fossil-collecting expedition to Cope's marl pits in New Jersey, where William Parker Foulke had discovered the holotype specimen of Hadrosaurus foulkii, described by the paleontologist Joseph Leidy (under whom Cope had studied comparative anatomy); this was one of the first American dinosaur finds, and the pits were still rich with fossils. Though the two parted amicably, Marsh secretly bribed the pit operators to divert future fossil finds to him, instead of Cope. The two began attacking each other in papers and publications, and their personal relations deteriorated. Marsh humiliated Cope by pointing out his reconstruction of the plesiosaur Elasmosaurus was flawed, with the head placed where the tail should have been (or so he claimed, 20 years later; it was Leidy who published the correction shortly afterwards). Cope, in turn, began collecting in what Marsh considered his private bone-hunting turf in Kansas and in Wyoming, further damaging their relationship

Personal Disputes

While Cope and Marsh dueled for fossils in the American West, they also tried their best to ruin each other's professional credibility. Humiliated by his error in reconstructing the plesiosaur Elasmosaurus, Cope tried to cover up his mistake by purchasing every copy he could find of the journal it was published in. Marsh, meanwhile, made sure to publicize the story. Cope's own rapid and prodigious output of scientific papers meant that Marsh had no difficulty in finding occasional errors to lambast Cope with. Marsh himself was not infallible; he put the wrong skull on a skeleton of Apatosaurus and declared it a new genus, Brontosaurus.

By the late 1880s, public attention to the fighting between Cope and Marsh faded, drawn to international stories rather than the "Wild West". Thanks to John Wesley Powell, head of the U.S. Geological Survey, and Marsh's contacts with the rich and powerful in Washington, Marsh was placed at the head of the consolidated government survey and was happy to be out of the sensationalist spotlight. Cope was much less well-off, having spent most of his money purchasing The American Naturalist, and had a hard time finding employment thanks to Marsh's allies in higher education and Cope's own temperament. Cope began investing in gold and silver prospects in the West, and braved malarial mosquitos and harsh weather to search for fossils himself. Due to setbacks in mining and a lack of support from the federal government, Cope's financial situation steadily deteriorated, to the point that his fossil collection was his only significant asset. Marsh, meanwhile, alienated even his loyal assistants, including Williston, with his refusal to share his conclusions drawn from their findings, and his continually lax and infrequent payment schedule.

Cope's chance to exploit Marsh's vulnerabilities came in 1884, when Congress began to investigate the proceedings of the consolidated geological survey. Cope had become friends with Henry Fairfield Osborn, then a professor of anatomy at Princeton University. Osborn was like Marsh in many ways, slow and methodical, but would prove a damaging influence on Marsh. Cope searched for disgruntled workers who would speak out against Powell and the Survey. For the moment, Powell and Marsh were able to successfully refute Cope's charges, and his allegations did not reach the mainstream press. Osborn seemed reluctant to step up his campaign against Marsh, so Cope turned to another ally he had mentioned to Osborn—a "newspaper man from New York" named William Hosea Ballou. Despite setbacks in trying to oust Marsh from his presidency of the National Academy of Sciences, Cope received a tremendous financial boost after the University of Pennsylvania offered him a teaching job.
