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.
On land, early flowering plants were blooming in the state. [3] The fossil of the hadrosaurid dinosaur Parrosaurus have been found in Bollinger County. In fact, fossils of Parrosaurus are among the only known dinosaur remains in the state. [3] The Mississippi embayment still covered part of Missouri during the early Cenozoic.

During the Early Cretaceous, new dinosaurs evolved to replace the old ones. Sauropods were still present, but they were not as diverse as they were in the Jurassic Period. Theropods from the Early Cretaceous of North America include dromaeosaurids such as Deinonychus and Utahraptor, the carnosaur Acrocanthosaurus, and the coelurosaur Microvenator.
Family: Canidae Genus: Canis Coyote, Canis latrans; Gray wolf, Canis lupus extirpated . Great Plains wolf, C. l. nubilus extinct; Red wolf, Canis rufus extirpated [2 ...
New remains of Parrosaurus, including dental remains [9] and part of a jaw, were found, [10] and remains of other dinosaurs, fish, turtles, and plants have also been found, including teeth belonging to a member of the Tyrannosauroidea. [3] [11] [12] In the 1980s, test excavations were performed at the site by Bruce L. Stinchcomb.
This is an incomplete list of prehistoric mammals. It does not include extant mammals or recently extinct mammals . For extinct primate species, see: list of fossil primates .
Figure 1:In mammals, the quadrate and articular bones are small and part of the middle ear; the lower jaw consists only of dentary bone.. While living mammal species can be identified by the presence of milk-producing mammary glands in the females, other features are required when classifying fossils, because mammary glands and other soft-tissue features are not visible in fossils.
