Koolasuchus

Koolasuchus is an extinct genus of brachyopoid temnospondyl in the family Chigutisauridae, known from fossils found in the Wonthaggi Formation in Victoria, Australia, dating to about 125 to 120 million years ago in the Barremian and Aptian stages of the Early Cretaceous. It is the youngest known temnospondyl, known from fragments of the skull and other bones including vertebrae, ribs, and pectoral elements. The type and only named species, Koolasuchus cleelandi, was described in 1997, and was adopted as the fossil emblem of the state of Victoria, Australia, in 2022.
