Paleontology in Missouri refers to paleontological research occurring within or conducted by people from the U.S. state of Missouri. The geologic column of Missouri spans all of geologic history from the Precambrian to present with the exception of the Permian, Triassic, and Jurassic. Brachiopods are probably the most common fossils in Missouri. During the Ice Age the northern part of the state was covered in glaciers while the southern half was home to creatures like camels, mammoths, and mastodons. The state's mastodons are among the most prominent of its Ice Age mammal fauna.
