* Coal (the state mineral of Kentucky and the state rock of Utah) is neither a rock nor a mineral, but a fossil fuel. Petrified wood (state gem of Washington) is not a gem, but also a fossil.

**Michigan state "stone" (petoskey stone) is actually fossilized coral. Mississippi state stone (petrified wood) is also a fossil.

***Hawaii state "gem" (black coral) is the skeleton of a marine animal.

"geological" symbols are also listed on the state fossils / dinosaurs list - black coral on state fish and waterlife list
