Discover the true story of the race between two paleontologists to find the best dinosaur fossils in this fascinating, fast-paced nonfiction picture book. Who will win the Bone Wars?

Did you know that many of the dinosaur skeletons you see in museums are rooted in a scientific battle between two paleontologists? O. C. Marsh and Edward Cope met in 1863 and bonded over their shared love of fossils, becoming the best of friends…until the day Marsh discovered an error in Cope’s work, and the Bone Wars began!

Marsh and Cope stopped collaborating and started competing, excavating fossils as fast as they could, and trying to find the most important never-before-seen discoveries. They each wanted the biggest, best dinosaur bones. And fast! They used code names and disguises, they snooped and tricked, and did everything possible to keep their finds secret. The race was messy and there were many mistakes along the way, but in the end, Marsh and Cope discovered all kinds of new dinosaur skeletons to share with the world—fossils we still get to see today!
