This week on a new and improved Footnotes (we ritualistically burned my desk and added a second camera at no small expense), we’re talking about the greatest rivalry the field of paleontology has ever seen: Edward Drinker Cope vs. Othniel Marsh, two men with differing views on how exactly velociraptors painted their nails. Join us as we track a competition that ended with two broke, ruined scientists and at least one dinosaur with, no joke, its head attached to the wrong end of its body.
