List of U.S. state dinosaurs

From Wikipedia, the free encyclopedia

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".
