The Bone Wars was the name given to a bitter competition between two paleontologists, Yale's O.C. Marsh and Edward Drinker Cope of Philadelphia. Lamanna says their mutual dislike, paired with their scientific ambition, led them to race dinosaur names into publication, each trying to outdo the other.
