Wantzosaurus was a genus of temnospondyl amphibian of the Trematosauridae family. Fossils have been found in the Early Triassic Middle Sakamena Formation (Sakamena Group) of what is now Madagascar. It showed adaptations for an almost completely aquatic lifestyle, having the ability to swim by lateral undulation.{{cite journal |last1=Steyer |first1=J.
