Microposaurus (meaning "small eyed lizard"; from Greek μικρός, "small" + ὤψ, "face" or "eye" + σαῦρος, "lizard") is an extinct genus of trematosaurid temnospondyl. Fossils are known from the Cynognathus Assemblage Zone of the Beaufort Group (part of the Karoo Supergroup) in South Africa and the Rouse Hill Siltstone of Australia that date back to the Anisian stage of the Middle Triassic.[1][2] These aquatic creatures were the short snouted lineage from Trematosaurinae.[1]
