Dinosaur wars (2011)

Dinosaur Wars is the story of two talented scientists, O.C. Marsh and Edward Cope, whose once professional rivalry soured into a bitter personal feud. Together, Marsh and Cope were responsible for identifying more than 142 different species and for introducing dinosaurs into the American imagination, but their legacy would be forever marred by two decades of ruthless infighting, espionage, and sabotage.
