Gosfordia is an extinct genus of prehistoric freshwater lungfish known from the Triassic of Australia.[1] It contains a single species, G. truncata from the early-mid Triassic (late Olenekian or early Anisian)-aged Terrigal Formation of New South Wales.[2] It is thought to be an early-diverging member of the Ceratodontiformes, making it a distant relative of extant lungfish.[3]
Initially based on five incomplete specimens of imperfect preservation, a complete specimen was described in 1981.[4] Skull bones described in 1994 suggest a close relationship between Gosfordia and Paraceratodus.[5] However, other studies suggest that it may have diverged prior to Paraceratodus.[6]
