<!--[[File:Statefossil 2016-02-02.png|right|thumb|300px|Map showing which states have state fossils (in blue; states without fossils are gray.)]]-->
Most states in the US have designated a '''state fossil''', many during the 1980s. It is common to designate a fossilized species, rather than a single specimen or a category of fossils. State fossils are distinct from other state emblems like [[state dinosaur]]s, [[state stone]]s, [[state mineral]]s, [[state gemstone]]s or [[state rock]]s and a state may designate one, a few, or all of those. For example, in [[Arizona]], the state stone is [[turquoise]] and the state dinosaur is ''[[Sonorasaurus thompsoni]]'' yet the state fossil is [[petrified wood]].

The two first states to designate a state fossil were [[Nebraska]] and [[North Dakota]], both in 1967.

Seven states and the District of Columbia still lack an explicit state fossil:

* [[Arkansas]]: still no state fossil in Arkansas, though the state designated ''[[Arkansaurus]]'' as its [[state dinosaur]].<ref>{{cite web | url=https://www.fossilera.com/pages/arkansas-state-fossil-arkansaurus | title= Arkansas State Fossil - Arkansaurus - While Arkansas does not officially have a state fossil it does have a state dinosaur | access-date= August 31, 2024 | work= State Symbols, State Fossil | publisher= Fossilera}}</ref>
* [[District of Columbia]]: ''[[Capitalsaurus]]'' is the state dinosaur of Washington D.C., but the District has not chosen a state fossil.
* [[Florida]]: There is no state fossil in Florida, though [[Agate|agatised]] [[coral]], which is a fossil, is the [[state stone]].
* [[Hawaii]]
* [[Iowa]]: The [[crinoid]] was proposed in 2018.<ref>{{Cite web|date=January 23, 2018|title=Iowa to consider recognizing official state fossil|url=https://www.seattletimes.com/nation-world/iowa-to-consider-recognizing-official-state-fossil/|website=The Seattle Times}}</ref>
