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 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.
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.

About 280 million years ago, a large creature built somewhat like a salamander but with frightful fangs prowled the swamps and lakes of what is now Namibia, ambushing prey as a top predator in a ...
