Eryops is a genus of amphibian of the Order Temnospondyli and was one of the largest amphibians (5-10 feet long) of the Permian Period.  Its well-ossified skeleton and large limbs are indicators that it had a more terrestrial lifestyle than its ancestors.  These kinds of adaptations were seen among some other amphibians as climates became drier across the Permian.
