Official State Dinosaurs and Fossils

State fossils or state dinosaurs have been named by 42 of the 50 states. Maryland, Missouri, Oklahoma, and Wyoming have named one of each, while Kansas has named both an official marine and flying fossil. Three states (Georgia, Oregon, and Vermont) have fossils of now-extinct species. There is also the informally named but formally designated "Capitalsaurus" of Washington, D.C. 

The state fossils make a much more consistent list than the state rocks, state minerals, and state gemstones. Most are distinct creatures identified by species. On the other hand, some of the dinosaurs are honored as state fossils rather than state dinosaurs.
