The Bone Wars: How a Petty Feud Almost Destroyed Paleontology

Few rivalries in scientific history are as dramatic, destructive, and oddly entertaining as the feud between Edward Drinker Cope and Othniel Charles Marsh. Between 1864 and Cope’s death in 1897, these two men didn’t just compete—they waged an all-out war for fossil supremacy. Their conflict, later known as the Bone Wars, helped build modern paleontology while simultaneously staining its reputation for decades.

This is the strange, explosive story of how ego, ambition, and dinosaurs collided.

A Rivalry Born in Academia

Ironically, Cope and Marsh didn’t start out as enemies. They met in Berlin in 1864 while studying abroad and were impressed enough with each other’s work to name dinosaur species after one another. That brief camaraderie didn’t last long.

Both men were brilliant, ambitious, and deeply competitive—an unstable combination. As fossil discoveries in America exploded in the mid-19th century, cooperation gave way to obsession.

When Pettiness Turned Explosive

The feud quickly escalated beyond academic sniping. Cope and Marsh routinely destroyed their own dig sites with dynamite just to prevent the other from returning and finding overlooked fossils. It’s impossible to know how many species were lost forever thanks to this scorched-earth approach to science.

Their rivalry was so intense that it bordered on absurd—and criminal.

The Skeleton in the Wrong Place

One of the most famous moments in the Bone Wars came when Cope incorrectly reconstructed an Elasmosaurus, placing its skull at the end of its tail. Marsh publicly humiliated him by pointing out the error in a letter to The New York Herald.

In reality, it was Cope’s mentor, Joseph Leidy, who first noticed the mistake. Mortified, Cope reportedly tried to buy up and destroy every journal that had published the incorrect reconstruction—an early example of academic damage control gone wrong.

Sloppy Science, Lasting Impact

The Bone Wars produced an astonishing number of discoveries—142 dinosaur species claimed between the two men. But speed mattered more than accuracy. Today, fewer than 40% of those species are considered valid.

Cope was even blamed for the famous Brontosaurus vs. Apatosaurus controversy, when a specimen was misidentified as a new species. Ironically, modern research in 2015 vindicated him—Brontosaurus was officially resurrected after all.

Bribes, Spies, and Dinosaur Rustlers

Scientific rivalry soon gave way to outright sabotage. Both men hired agents, students, and even armed “dinosaur rustlers” to spy on digs, steal fossils, intimidate workers, and sabotage excavations. Rocks were thrown. Guns were nearly drawn.

Marsh, backed by his wealthy uncle George Peabody, often used bribery to secure fossils. Cope, though less wealthy over time, was no stranger to dirty tactics himself.

Railroads and the Race West

The expansion of America’s railroads opened the fossil-rich West, and both men rushed to exploit it. Wyoming, Colorado, and beyond yielded legendary discoveries like Triceratops, Stegosaurus, and Allosaurus.

But even here, the rivalry poisoned progress. Railroad workers manipulated Marsh’s desperation to outbid Cope, demanding absurd prices for fossils—knowing Marsh would pay almost anything to “win.”

The Fall of Two Titans

In the 1880s, Marsh became head of the U.S. Geological Survey and passed a law stating that fossils collected with government funding belonged to the Smithsonian. The move was meant to cripple Cope—but it backfired.

Cope exposed Marsh’s misconduct in a damning public record, backed by former employees. Marsh was forced to resign, and because he couldn’t prove ownership of many fossils, most of his collection was seized by the very institution he tried to weaponize.

Both men died poor, disgraced, and embittered—casualties of their own rivalry.

The Quiet Winner: Joseph Leidy

While Cope and Marsh destroyed each other, Joseph Leidy walked away. Tired of the chaos, he abandoned dinosaur hunting and went on to discover more than 400 species of protozoans and invertebrates.

The Smithsonian also benefited, inheriting a massive fossil collection thanks to the Bone Wars’ self-inflicted damage.

One Last Petty Move

Cope’s final act was unforgettable. In his will, he requested that his brain be removed and weighed, challenging Marsh to do the same to prove intellectual superiority—even in death.

Marsh declined.

And with that, the Bone Wars finally ended.

Legacy of the Bone Wars

The rivalry between Cope and Marsh advanced palaeontology more than any other period in its early history—but at a terrible cost. Sloppy science, destroyed fossils, and unethical behaviour left a dark stain that lingered for generations.

In the midst of the brutal feud, both men greatly expanded our understanding of evolution. Nonetheless, their egotistical one-upmanship is a vivid reminder that for all its trappings, science is a personal enterprise conducted by individuals and, at times, deeply flawed human beings
