The Bone Wars, also known as the Great Dinosaur Rush,[1] 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 of 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 the 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 they made important contributions to science and the field of paleontology 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 more than 136 new species of
prehistoric
life, and sparked the public's interest in dinosaurs, leading to continued fossil excavation in North America in the decades to follow. Many historical books and fictional adaptations have been published about this period of intense fossil-hunting activity.
History
Background
At first, the relationship between Edward Drinker Cope and Othniel Charles Marsh was amicable. They met in Berlin in 1864 and spent several days together. They even named
Neo-Lamarckism while Marsh supported Charles Darwin's theory of evolution by natural selection.[4] 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."[5]
Cope and Marsh came from very different backgrounds. Cope was born into a wealthy and influential
Lockport, New York, had it not been for the benefaction of his uncle, philanthropist George Peabody.[6] 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).[7]
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.[2] Though the two parted amicably, Marsh secretly bribed the pit operators to divert future fossil finds to him, instead of Cope.[2] The two began attacking each other in papers and publications, and their personal relations deteriorated.[8] Marsh humiliated Cope by pointing out that 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;[9] it was Leidy who published the correction shortly afterwards).[10] Cope, in turn, began collecting in what Marsh considered his private bone-hunting turf in Kansas and Wyoming, further damaging their relationship.[8][11]
1872–1877: Early expeditions
In the 1870s, Cope's and Marsh's professional attentions were directed to the American West by word of large fossil finds. Using his influence in Washington, D.C., Cope was granted a position on the U.S. Geological Survey under Ferdinand Hayden. While the position offered no salary, it afforded Cope a great opportunity to collect fossils in the West and publish his finds. Cope's flair for dramatic writing suited Hayden, who needed to make a popular impression with the official survey reports. In June 1872 Cope set off on his first trip, intending to observe the Eocene bone beds of Wyoming for himself. This caused a rift between Cope, Hayden, and Leidy. It was Leidy who had enjoyed receiving many of the fossils from Hayden's collection until Cope joined the survey, and now Cope was hunting for fossils in Leidy's staked territory—at the same time Leidy was to be collecting.[12] Hayden attempted to smooth things over with Leidy in a letter:
I asked him not to go into that field, that you were going there. He laughed at the idea of being restricted to any locality and said he intended to go whether I aided him or not. I was anxious to secure the cooperation of such a worker as an honor to my corps. I could not be responsible for the field he selected in as much as I pay him no salary and a portion of his expenses. You will see therefore that while it is not a pleasant thing to work in competition with others it seems almost a necessity. You can sympathize.[12]
Cope took his family with him as far as Denver, while Hayden tried to keep Cope and Leidy from prospecting in the same area. Following a tip from geologist Fielding Bradford Meek, Cope also intended to investigate reports of bones Meek had found near Black Buttes Station and the railroad. Cope found the site and some skeletal remains of a dinosaur he dubbed Agathaumas sylvestris.[13] Believing he had the full support of Hayden and the survey, Cope then traveled to Fort Bridger in June, only to find that the men, wagons, horses, and equipment he expected were not there.[14] Cope cobbled together an outfit at his own expense, consisting of two teamsters, a cook, and a guide,[15] along with three men from Chicago who were interested in studying with him.[14] As it turned out, two of Cope's men were in fact in the employ of Marsh. When the rival paleontologist found out his own men were taking Cope's money, he was furious. While the men tried to assure Marsh they were still his men (one suggested he took the job in order to lead Cope away from good fossils), Marsh's laziness in soliciting firm agreements and payments may have caused them to seek other work.[16] Cope's journey took the expedition through rugged country only Hayden had surveyed, and he discovered dozens of new species. Meanwhile, one of Marsh's men accidentally forwarded some of his material to Cope instead. On receiving the fossils, Cope sent them back to Marsh, but further damage had been done to their relationship.[17]
Any pretense of cordiality between Cope and Marsh ended in 1872,
Tinoceras. The problem was that many of these finds were not uniquely different from each other; in fact, Cope and Marsh knew that some of the fossils they were collecting had already been found by the others.[21] As it turned out, many of Marsh's names were valid, while none of Cope's were. Marsh also placed the new species into a new order of mammals, Cinocerea. Cope was humiliated and powerless to stop his rival's changes. Instead, he published a broad analytical study where he proposed a new plan of classification for the Eocene mammals, in which he discarded Marsh's genera in favor of his own. Marsh remained steadfast and continued to claim that all of Cope's names for Dinocerata were incorrect.[22]
While the scientists argued over classifications and nomenclature, they also returned west for more fossils. Marsh made his last trip backed by Yale in 1873, with a large group of thirteen students accompanying him, protected by a group of soldiers who wanted to make a show of force to the Sioux tribe. Due to concerns over his more lavish and expensive expeditions in years past, Marsh had the students pay their own way, and the trip cost Yale only $1857.50, far less than the $15,000 (over $200,000 in modern currency) that Marsh had claimed for the previous expedition. This excursion would prove to be Marsh's last: for the rest of the Bone Wars, Marsh preferred to enlist the services of local collectors. Though he had enough bones to study for years, the scientist's appetite for more would grow.[23] Cope was even more prolific in his collecting that season than he was in 1872, although Marsh's penchant for cultivating collectors of his own meant that at Bridger his rival was persona non grata. Tired of working under Hayden, Cope found a paying job with the Army Corps of Engineers, but was limited by this federal association; while Cope had to tag along on surveys, Marsh could collect wherever he pleased.[24]
The two scientists' attention turned to the
Chief Red Cloud of the Sioux to prospect, Marsh promised Red Cloud payment for fossils collected and that he would return to Washington, D.C. and lobby on their behalf about their improper treatment. In the end, Marsh slipped out of camp and according to his own (possibly romanticized) accounts, amassed cartloads of fossils and retreated just before a hostile Miniconjou party arrived.[26] Marsh, for his part, did lobby the Interior Department and President Ulysses S. Grant on behalf of Red Cloud, but his motives might have been to make a name for himself against the unpopular Grant administration.[27] By 1875, both Cope and Marsh paused in their collecting, feeling financial strain and needing to catalogue their backlogged finds, but new discoveries would return them to the West before decade's end.[28]
1877–1892: Como Bluff finds
In 1877, Marsh received a letter from Arthur Lakes, a schoolteacher in Golden, Colorado. Lakes reported that he had been hiking in the mountains near the town of Morrison, when he and his friend, H. C. Beckwith, discovered massive bones embedded in the rock. Lakes further advised that the bones were "apparently a vertebra and a humerus bone of some gigantic saurian."[29] While awaiting Marsh's reply, Lakes dug up more "colossal" bones and sent them to New Haven. As Marsh was slow to respond, Lakes also sent a shipment of bones to Cope.[30]
When Marsh responded to Lakes, he paid the prospector $100, urging him to keep the finds a secret. Learning that Lakes had corresponded with Cope, Marsh sent his field collector
Benjamin Mudge to Morrison to secure Lakes' services. Marsh published a description of Lakes' discoveries in the American Journal of Science on July 1, and before Cope could publish his own interpretation of the finds, Lakes wrote to him that the bones should be shipped to Marsh, a severe insult to Cope.[30]
A second letter arrived from the west, this time addressed to Cope. The writer, O. W. Lucas, was a naturalist who had been collecting plants near Cañon City, Colorado when he came upon an assortment of fossil bones. After receiving more samples from Lucas, Cope concluded the dinosaurs were large herbivores, gleefully noting that the specimen was larger than any other previously described, including Lakes' discovery.[30][31] Hearing of Lucas' finds, Marsh instructed Mudge and a former student, Samuel Wendell Williston, to set up a quarry on his behalf near Cañon. Unfortunately for Marsh, he learned from Williston that Lucas was finding the best bones and refused to quit Cope to come work for Marsh.[18] Marsh ordered Williston back to Morrison, where Marsh's small quarry collapsed and nearly killed his assistants. This setback would have dried up Marsh's bone supply from the west, if not for receipt of a third letter.[32]
At the time of Lakes' discoveries, the First transcontinental railroad was being built through a remote area of Wyoming. Marsh's letter was from two men identifying themselves as Harlow and Edwards, workers on the Union Pacific Railroad. Their real names were William Harlow Reed (1848–1915) and William Edwards Carlin.[33] The two men claimed they had found large numbers of fossils in Como Bluff, and warned that there were others in the area "looking for such things",[34] which Marsh took to mean Cope. Williston, who had just wearily arrived in Kansas after the collapse of the Morrison mine,[35] was quickly dispatched to Como Bluff by Marsh. His former student sent back a message, confirming the large quantities of bones and that it was Cope's men snooping around the area.[36] Wary of repeating the same mistakes he had made with Lakes, Marsh quickly sent money to the two new bone hunters and urged them to send additional fossils.[35] Williston struck a preliminary bargain with Carlin and Reed (who had been unable to cash Marsh's check due to it being made out to their pseudonyms), but Carlin decided he would head to New Haven to deal with Marsh directly.[37] Marsh drew up a contract calling for a set monthly fee, with additional cash bonuses to Carlin and Reed possible, depending on the importance of the finds. Marsh also reserved the right to send his own "superintendents" to supervise the digging if needed and advised the men to try to keep Cope out of the region.[38] Despite a face-to-face meeting, Carlin failed to negotiate better terms from Marsh. The paleontologist procured Carlin's and Reed's services, but seeds of resentment were sown as the bone hunters felt Marsh had bullied them into the deal.[38] Marsh's investment in the Como Bluff region soon produced rich results. While Marsh's own collectors headed east for the winter, Reed sent carloads of bones by rail to Marsh throughout 1877. Marsh described and named dinosaurs such as Stegosaurus, Allosaurus, and Apatosaurus in the December 1877 issue of the American Journal of Science.[39]
Despite Marsh's precautions against alerting his rival to Como Bluff's rich bone beds, word of the discoveries rapidly spread. This was at least partly due to Carlin and Reed helping spread the rumors. They leaked information to the Laramie Daily Sentinel, which published an article about the finds in April 1878 that exaggerated the price Marsh had paid for the bones, possibly to raise prices and demand for more bones.[40] Marsh, attempting to cover the leak, learned from Williston that Carlin and Reed had been visited by a man ostensibly working for Cope by the name of "Haines".[40] After learning of the Como Bluff discoveries, Cope sent "dinosaur rustlers" to the area in an attempt to quietly steal fossils from under Marsh's nose.[41] During the winter of 1878, Carlin's dissatisfaction with Marsh's sporadic sending of payment reached a head, and he began working for Cope instead.
Cope and Marsh used their personal wealth to fund expeditions each summer, then spent the winter publishing their discoveries. Small armies of fossil hunters in mule-drawn wagons or on trains were soon sending literally tons of fossils back east.[42] The paleontological digs lasted fifteen years, from 1877 to 1892.[41] The workers for both Cope and Marsh suffered hardships related to the weather, as well as sabotage and obstruction by the other scientist's workers. Reed was locked out of the Como train station by Carlin, and was forced to haul the bones down the bluff and crate the specimens on the train platform in the bitter cold.[43] Cope directed Carlin to set up his own quarry in Como Bluff, while Marsh sent Reed to spy on his former friend. As Reed's Quarry #4 dried up, Marsh ordered Reed to clear out the bone fragments from the other quarries. Reed reported he had destroyed all the remaining bones to keep them away from Cope.[44] Concerned that strangers were encroaching on Reed's quarries, Marsh sent Lakes to Como to assist in excavations,[45] and in June 1879 visited Como himself. Cope likewise toured his own quarries in August. Although Marsh's men continued to open new quarries and discover more fossils, relations between Lakes and Reed soured, with each offering his resignation in August. Marsh attempted to placate the two by sending each to opposite ends of the quarries,[46] but after being forced to abandon one bone quarry in a freezing blizzard, Lakes submitted his resignation and returned to teaching in 1880.[47] The departure of Lakes did not ease tensions among Marsh's men; Lake's replacement, a railroad man named Kennedy, felt he did not have to report to Reed, and the fighting between the two caused Marsh's other workers to quit. Marsh tried separating Kennedy and Reed, and sent Williston's brother Frank to Como in an effort to keep the peace. Frank Williston ended up leaving Marsh's employ and taking up residence with Carlin.[48] Cope's own digging in Como began faltering, and Carlin's replacements soon quit work altogether.[48]
