Dimetrodon occidentalis was named in 1977 from New Mexico. [50] Its name means "western Dimetrodon" because it is the only North American species of Dimetrodon known west of Texas and Oklahoma. It was named on the basis of a single skeleton belonging to a relatively small individual.

However, Sigi Maho and colleagues have pointed out that several genera of Permian tetrapods had a wide temporal distribution, such as Dimetrodon and Diplocaulus, and that the presence of the genus Macroleter in both Russia and Oklahoma (represented by two different species) is not an evidence of a middle Permian age for the Chickasha Formation ...
The best source of Mississippian fossils in Oklahoma is the state's northeastern region. [2] During the Carboniferous, Oklahoma was a terrestrial environment characterized by vast river systems and accompanying deltas. These deltas were home to vast swamps responsible for leaving behind many coal deposits. [3]
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.
Dimetrodon is an extinct genus of synapsid that lived during the Early Permian, around 299–270 million years ago (Ma). It is a member of the family Sphenacodontidae . The most prominent feature of Dimetrodon is the large sail on its back formed by elongated spines extending from the vertebrae.
The state’s coastal marshes, which author Owens placed around the fictional town of Barkley Cove, account for most of the setting. Real-life locations of Chapel Hill, Asheville and Greenville ...
Precursors to mammals like Dimetrodon and Edaphosaurus lived in Texas. [19] At the end of the Permian the largest mass extinction in earth's history occurred, killing some 96% of species on the planet. [18] During the Triassic, the Mesozoic era began. [20] Ichthyosaurs entered the sea and achieved large sizes in Nevada. [21]
