The first book in the Unhinged History series is a ripping yarn—full of adventure and deceit—that brings to life the best-known public spat in all of paleontology: the bitter rivalry between Edward Drinker Cope and Othniel Charles Marsh. This frenzy of discovery and one-upmanship—known today as the Bone Wars—was a gold rush–like scramble to find the most and “best” dinosaur fossils, thus bringing to glory to their respective home-base universities. Lively and witty rhymes plus wonderfully demented illustrations reveal how the paleontologists’ infamous rivalry began, and how—despite making genuine and lasting contributions to the field—their mutual obsession with outdoing one another spun out of control.
