This article contains a list of fossil-bearing stratigraphic units in the state of Oklahoma, U.S. Sites. Group or Formation
Oklahoma was a terrestrial environment for most of the ensuing Mesozoic era. [3] The Late Triassic Dockum Group of western Oklahoma preserved remains of archosaurs and temnospondyls, although its fossil record is restricted to a narrow region of the panhandle and is far sparser than the equivalent records in Texas, New Mexico, and Arizona.

This list of the Paleozoic life of Oklahoma contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Oklahoma and are between 541 and 252.17 million years of age.
Richards Spur is a Permian fossil locality located at the Dolese Brothers Limestone Quarry north of Lawton, Oklahoma. The locality preserves clay and mudstone fissure fills of a karst system eroded out of Ordovician limestone and dolomite , with the infilling dating to the Artinskian stage of the early Permian ( Cisuralian ), around 289 to 286 ...
The Texas and Oklahoma red beds are sedimentary rocks, mostly consisting of sandstone and red mudstone. [8] The red color of the rocks is due to the presence of ferric oxide . [ 9 ] The rocks were deposited during the early Permian in a warm, moist climate, [ 10 ] with seasonal periods of dry conditions.
The fossil itself has a somewhat less poetic name: NDGS 10838. It includes a near-complete skull with a bony ridge over the eyes as well as jaws and some skeletal parts, including 11 ribs and 12 ...
The fossil was found near the Giant Fitts Oilfield. The petrified stump was the largest of its species to ever be discovered. The Callixylon tree is an example of Callixylon whiteanum, a species of extinct trees found in the late Devonian period. [2] It was later discovered to be a member of the same family as the genus Archaeopteris. [3]
