The Chickasha Formation is a geologic formation in Oklahoma. 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 Olson.[5]
