List of U.S. state dinosaurs

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". 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.
