It preserves fossils dating back to the Roadian stage of the Middle Permian.
[2] These include, among others, the dissorophoid temnospondyl Nooxobeia gracilis,[3] the lepospondyl Diplocaulus parvus (Amphibia: Nectridea),[4] and the captorhinid Rothianiscus robusta, initially called Rothia robusta by Everett C.
[5] Many of these fossils were indicated to have come from the Flowerpot Shale, but these actually come from the Chickasha Formation, according to the current nomenclature.
[6] The age of the formation was long debated because Olson based part of his argument on fragmentary fossils that he interpreted as therapsids, an interpretation that was not widely accepted.
