The Nocona Formation is a geological formation in Texas, dating back to the Wolfcampian series (Early Permian). As part of the Texas red beds, it is one of several formations renowned for dense bonebeds of terrestrial vertebrate fossils.[1][2] The Nocona Formation was named as a distinct geological unit in 1987; its layers and bonebed were previously assigned to the Admiral Formation, a time-equivalent marine deposit located further south in Texas.[3][4]
