Parioxys is an extinct genus of temnospondyl amphibian from the Early Permian of Texas. The genus includes the type species Parioxys ferricolus, named by paleontologist Edward Drinker Cope in 1878, and the species Perioxys bolli, named by paleontologist Robert L. Carroll in 1964.[1] Parioxys was first classified as a close relative of Eryops, another temnospondyl from Texas, and was later assigned to the family Trematopidae. In 1955, Parioxys was placed as the sole member of the newly erected family Parioxyidae. Parioxys is now considered a closer relative of Eryops than trematopids, and both Parioxys and Eryops are placed in the group Eryopoidea.[2]
