Marsh meets "Buffalo" Bill Cody, who serves as their guide, along with a Native American Indian tribe. Marsh discovers many new fossils, and promises to Chief Red Cloud that he will talk to the President of the United States about his people's situation. Back East, Knight has finished his reconstruction of Elasmosaurus. He and Knight return to the marl pits. Cope becomes furious when he learns Marsh has bought the digging rights and published a paper revealing his reconstruction of Elasmosaurus as flawed. Some time later, bone hunter John Bell Hatcher has taken to gambling, as Marsh is not providing him with enough funds. Marsh lobbies the Bureau of Indian Affairs on behalf of Red Cloud, but also visits with the USGS, insinuating that he would be a better leader than Cope. After learning about Sam Smith's attempted sabotage of Cope and once again receiving no payment from Marsh, Hatcher leaves his employ. Marsh, now representing the survey, heads west with wealthy businessmen, scoffing at the financial misfortunes of Cope, whose investments have failed. Cope travels with Knight to Europe; Knight with the intention of visiting Parisian zoos, Cope with the intent of selling off much of his bone collection. Cope has spent much of his money buying The American Naturalist, a paper in which he plans to attack Marsh. Hatcher arrives in New York to talk about the find Laelaps; in his speech, he hints at the folly of Marsh's elitism and Cope's collecting obsession. Marsh learns that his USGS expense tab (to which he had been charging drinks) has been withdrawn, his publication has been suspended, and the fossils he found as part of the USGS are to be returned to the Survey. His colleagues now shun him, the Bone Wars feud having alienated them. He is forced to go to Barnum to try to obtain a loan. Osborn and Knight arrive at Cope's residence to find the paleontologist has died of illness. The funeral is attended only by the two friends and a few Quakers. Cope has bequeathed his remains to science, and requested to have his bones considered for the Homo sapiens lectotype. Back at Marsh's residence, the visiting Chief Red Cloud examines Marsh's luxuries. Red Cloud's interest is piqued by a long tusk from a mastodon. Marsh relates an ancient Shawnee legend that once there were giant men proportionate to the mastodons before they died
