The Red Beds of Texas and Oklahoma are a group of Early Permian -age geologic strata in the southwestern United States cropping out in north-central Texas and south-central Oklahoma. They comprise several stratigraphic groups, including the Clear Fork Group, the Wichita Group, and the Pease River Group. [1] The Red Beds were first explored by ...
Plant fossils were preserved in abundance in the Llano Uplift, north-central, and Trans Pecos Texas. Plant fossils from the latter two localities tended to be poorly preserved. [8] Very early reptile fossils are also known from the deposits of the Llano Uplift. [7] Dimetrodon. Permian fossils are widespread in Texas. [8]

Dimetrodon (/ daɪˈmiːtrəˌdɒn / ⓘ [ 1 ] or / daɪˈmɛtrəˌdɒn /; [ 2 ]lit.'two measures of teeth') is an extinct genus of non- mammalian synapsid belonging to the family Sphenacodontidae that lived during the Cisuralian age of the Early Permian period, around 295–272 million years ago. [ 3 ][ 4 ][ 5 ] With most species measuring 1.7 ...
The Permian–Triassic extinction event, labeled "End P" here, is the most significant extinction event in this plot for marine genera which produce large numbers of fossils. The Permian ended with the most extensive extinction event recorded in paleontology: the Permian–Triassic extinction event. 90 to 95% of marine species became extinct ...
Trimerorhachis is an extinct genus of dvinosaurian temnospondyl within the family Trimerorhachidae. It is known from the Early Permian of the southwestern United States, with most fossil specimens having been found in the Texas Red Beds. The type species of Trimerorhachis, T. insignis, was named by American paleontologist Edward Drinker Cope in ...
Permian rocks are the best-known of the Texas Paleozoic. They are widespread in north Texas, where their characteristic red beds are spectacularly exposed in Palo Duro Canyon. The strata are also oil-rich where buried in west Texas, such as in the Midland and Odessa region. This crude oil-rich area is known as the Permian Basin.
