Last week we learned about some mistakes paleontologists made while working out what an extinct animal looked like using only a few fossilized bones. Mistakes are a normal part of the scientific method, no matter how silly they seem once we know more about the animal. But this week we’re going to look at some frauds and hoaxes in the paleontology world.

We really need to start with a man named Albert Koch. He was from Germany but moved to the United States in 1835, and was something of a cut-rate PT Barnum. He called himself Dr. Koch although he hadn’t earned a doctorate. A lot of the so-called curiosities he displayed were fakes.

Back in the mid-19th century, fossils had only recently been recognized as being from animals that lived millions of years before. People were still getting their heads around that concept, and around the idea that animal species could even go extinct. Then the fossils of huge animals started to be discovered—and not just discovered, but displayed in museums where the public could go look at them. Naturally they were big hits.

Sometimes these fossil exhibits weren’t free. For example, the mounted fossil skeleton of a mastodon was exhibited by the naturalist Charles Peale starting in 1802—one of the first fossil exhibits open to the public. Peale and his workers had mounted the skeleton to seem even larger than it really was by putting wooden discs between some of the bones. But the exhibit was primarily meant to educate, not just bring in money. It cost 50 cents to see the mastodon and lots of people wanted to. These days Peale’s mastodon is on display in Germany, without the wooden discs.

Albert Koch knew about Peale’s mastodon, and more to the point he knew how much money Peale had made off his mastodon. Koch wanted one for himself.

In 1840 he heard about a farmer in Missouri who had dug up some huge bones. Koch bought the bones and assembled them into a mastodon. But Koch wasn’t a paleontologist, he didn’t care about educating the public, and when he looked at those fossils, he just saw dollar signs. And he had ended up with bones from more than one mastodon, so, you know, he used them all. And he added wooden discs between the bones to make the animal bigger. A lot bigger. Between the wooden discs and the extra bones, Koch’s skeleton was twice the size of a real mastodon. Plus, he turned the tusks around so that they pointed upward, either because he didn’t know any better or because he thought that looked more exciting.

He called his mastodon Missourium and displayed it at his exhibit hall in St. Louis, Missouri later in 1840. It was a hit, and in 1841 he decided he’d make more money if he took Missourium on the road. He packed the massive skeleton up, sold his exhibit hall, and went on tour with just the mastodon.

Paleontologists spoke out against Koch’s Missourium as being unscientific, but that only gave him free publicity. People thronged to his exhibit for the next two years, until 1843 when he sold it to the British Museum. Needless to say, the experts at the British Museum promptly disassembled Missourium so they could study the fossils properly before remounting them into a mastodon that didn’t contain any extra ribs and vertebrae. Also, they put the tusks on the right way up.
