This is a list of U.S. state dinosaurs in the United States, including the District of Columbia. A large number of states also have dinosaurs as state fossils, but this list only includes those that have been officially designated as "state dinosaurs". Maiasaura (Montana), Coelophylolsis (New Mexico), Saurophaganax (Oklahoma), Triceratops (South Dakota), and Allosaurus (Utah) are state fossils.[1] In 1998, the legislature of Arizona was unable to decide on a state dinosaur, or indeed a state fossil. All U.S. states also have a state bird, which are biologically a subset of dinosaurs.
