Trematosauria are one of two major groups of Temnospondyl amphibians that survived the Permian-Triassic extinction event; the other (according to Yates and Warren 2000) being the Capitosauria. The Trematosaurs were a diverse and important group that included many medium-sized and large, semi-aquatic to totally aquatic, long-snouted to short broad headed forms. Although most groups did not survive beyond the Triassic, one lineage, the Chigutosauridae, continued until the Cretaceous period.An example is the trematosauroidea.
