Platyhystrix (plah-tee-hiss-stricks, meaning "flat porcupine") was a temnospondyl amphibian with a distinctive sail along its back, similar to the unrelated synapsids, Dimetrodon and Edaphosaurus. It lived during the Permian period (290 to 270 million years ago), in the United States (central). It coexisted with other, larger temnospondyls like Eryops, and may have been preyed upon by them.
