Plagiosaurus is an extinct genus of temnospondyl amphibian. The type and only species is P. depressus, first described by Otto Jaekel in 1914.^[1] Arthur Smith Woodward regarded the genus as a synonym of Plagiosternum, but most researchers consider it to be valid.^[2] It was paedomorphic, retaining the larval gills in adulthood. Like many stereospondyls, it had weak simplified vertebrae, consisting of large intercentra and neural arches, which is known as the stereospondylous condition.
