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.
The Permian (/ ˈ p ɜːr m i. ə n / PUR-mee-ən) [4] is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period 298.9 million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya.
The Pennsylvanian nautiloids of Missouri mostly had coiled shells but some forms were straight. Their remains are most common in the west-central region of the state. [2] Pennsylvanian marine vertebrate life included armored fishes. [9] On land, the Pennsylvanian plant life of Missouri included ferns, reeds, rushes, and scale trees.

This area, which Olson (1989) termed the "Classic area", has been extensively studied for its Permian plant and animal fossils. [7] The portions of the Arroyo Formation exposed in this area are among the oxidized Permian sediments collectively termed the Red Beds of Texas and Oklahoma.
One study tabulate the rates of origination and extinction of over 600 terrestrial and freshwater animal families. Their stratigraphic ranges spanned a geologic interval from the middle Paleozoic biotic invasion of the land to the Permian–Triassic extinction event. Insects comprise more than half of the sampled families, most of which are ...
