Microposaurus was a genus of temnospondyl of the Trematosauridae family. Fossils are present from the Cynognathus Assemblage Zone of the Beaufort Group (part of the Karoo Supergroup) in South Africa and date back to the Anisian stage of the Middle Triassic^[1]. A mandible from the Lower Anisian Mukheiris Formation in Jordan shares many similarities with the genus, including a similarly sized Meckelian fenestra on the inner surface of the lower jaw, teeth with sharp edges, and large fangs in the upper jaw.^[2]
