Okla. Stat. tit. 25, § 98.6

Because of the extraordinarily rich paleontological heritage of the State of Oklahoma, the Legislature hereby declares Saurophaganax Maximus to be the State Fossil of Oklahoma. This spectacular dinosaur, the “greatest king of reptile eaters”, once roamed this great land. It is only known from Oklahoma and has surpassed the Tyrannosaurus rex, the “king of the dinosaurs”, as the greatest predator of earth’s history.
