List of U.S. state dinosaurs

Template:Short description This is a list of U.S. state dinosaurs in the United States, including the District of Columbia. Many states also have dinosaurs as state fossils, or designate named avian dinosaurs (List of U.S. state birds), but this list only includes those that have been officially designated as "state dinosaurs". Most of these dinosaurs were recognized as such due to efforts from students.
