Map showing which states have state fossils (in blue; states without fossils are gray.)

Most American states have made a state fossil designation, in many cases during the 1980s. It is common to designate one species in which fossilization has occurred, rather than a single specimen, or a category of fossils not limited to a single species.

Some states that lack an explicit state fossil have nevertheless singled out a fossil for formal designation as a state dinosaur, rock, gem or stone.
