The Stereospondyli are a group of extinct temnospondyl amphibians. They had simplified backbones, where the whole vertebra was made of a single intercentrum, topped by a neural arch. The whole vertebral structure was rather weak, meaning that most stereospondyls were aquatic. The family Plagiosauridae appear to have been wholly aquatic and retained their larval gills in adulthood.

Stereospondyls first appeared during the Late Permian. During this time, the two major groups of stereospondyls, capitosaurians and trematosaurians, appeared. Stereospondyls were relatively uncommon in the Paleozoic, outnumbered by the more diverse euskelians. During this time, they were endemic to Gondwana. Many early groups of temnospondyls became extinct during the Permian-Triassic extinction event but stereospondyls likely survived in Australia or Antarctica, radiating worldwide in the Triassic.
