The Red Beds are a group of Early Permian-age geologic strata in the southwestern United States outcropping in north-central Texas and south-central Oklahoma. They comprise several stratigraphic groups including the Clear Fork Group, the Wichita Group, and the Pearce River Group.[1] The Red Beds were first explored by American paleontologist Edward Drinker Cope starting in 1877.[2] Fossil remains of many Permian tetrapods (four-limbed vertebrates) have been found in the Red Beds, including those of Dimetrodon, Edaphosaurus, Seymouria, Platyhystrix and Eryops. A recurring feature in many of these animals is the sail structure on their back.[3]
