Microposaurus is a genus of stereospondyl amphibian that lived during the early Triassic. For a long time Microposaurus fossils were only known from South Africa, but in 2012 a description of Microposaurus fossils from Australia was published. This also saw the creation of a second Microposaurus species, M. averyi. Fossil remains from Jordan have also been interpreted as being very similar to the known remains of Microposaurus.
