This list of the Paleozoic life of Missouri contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Missouri and are between 538.8 and 252.17 million years of age.
There is no Permian age rocks on the surface in Missouri, so beware of any fossils identified as such in the state.
