MrPotatoTed Posted November 29, 2021 Share Posted November 29, 2021 The first dinosaur fossil was discovered in 1677 -- but their best guess at the time was that it had belonged to a giant human. We didn't really figure out what dinosaurs were until 1842. This means that George Washington, John Adams, Thomas Jefferson, James Monroe, James Madison, and William Henry Harrison all died without any clue that dinosaurs had ever existed. The first ex-President with any chance of knowing about dinosaurs was John Quincey Adams, who died six years after their discovery, though I'm not aware of actual confirmation that he knew. The sitting President when they were discovered was John Tyler. And now you know! Quote Link to comment Share on other sites More sharing options...
