Bone Sharps, Cowboys, and Thunder Lizards by Jim Ottaviani & Big Time Attic

Two 19th century paleontologists, Edward Cope and Othniel Marsh, battled for scientific supremacy in the field of dinosaurs. The story is told in black and white comics with lively dialogue. The addition of a "Fact or Fiction?" section at the end clarifies where events were fudged a bit to make a better story, but the truth is often strange enough on its own. I preferred Ottaviani's biography of Niels Bohr, Suspended in Language, but Bone Sharps is accessible to a younger audience (meaning teens) and is more entertaining.
