Siderops2DB
''Siderops'' (from the Greek sideros meaning “iron” and -ops meaning “face” ) is an extinct genus of chigutisaurid temnospondyl from Early Jurassic of Australia, containing the species ''S. kehli'' (named after the Kehl family of ‘Kolane’, Wandoan, Queensland where the fossil was found). Discovery It is solely known from the holotype specimen, which consists of a nearly complete skull with mandible and postcrania were found within the Westgrove Ironstone Member of the Evergreen Formation of the Surat Basin in Queensland. Dating to the late Toarcian at approximately 176.6 ma. ''Siderops'' was large, with a skull width wide and a total length of . Classification ''Siderops'' belongs to the clade Brachyopomorpha, a subdivision of the greater clade Temnospondyl and placed in the superfamily Brachyopoidea and belonging in the Chigutisauridae family.

Brachyopoidea
Brachyopoidea is a superfamily of temnospondyls that lived during the Mesozoic. It contains the families Brachyopidae and Chigutisauridae. The earliest records of brachyopids are from the Lower Triassic in Australia. The latest-surviving member of the superfamily is the chigutisaurid '' Koolasuchus'' from the Early Cretaceous of Australia. Description Some large brachiopoids, such as ''Siderops'' and ''Koolasuchus'', grew to lengths of around . However, an unnamed Late Triassic or Early Jurassic brachiopoid from Lesotho in southern Africa is estimated to have been far larger. At an estimated , the brachiopoid from Lesotho is one of the largest amphibians ''sensu lato'' ever known. This estimate is based on a single jaw fragment found in 1970 by a French expedition near Alwynskop in Quthing. Because of its size, the fragment was initially considered to be from a mastodonsaur. However, Several features of the specimen indicate that it is from a brachyopoid. There is a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Temnospondyl
Temnospondyli (from Greek language, Greek τέμνειν, ''temnein'' 'to cut' and σπόνδυλος, ''spondylos'' 'vertebra') or temnospondyls is a diverse ancient order (biology), order of small to giant tetrapods—often considered Labyrinthodontia, primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent. A few species continued into the Jurassic and Early Cretaceous periods, but all had gone extinct by the Late Cretaceous. During about 210 million years of evolutionary history, they adapted to a wide range of habitats, including freshwater, terrestrial, and even coastal marine environments. Their life history is well understood, with fossils known from the larval stage, metamorphosis and maturity. Most temnospondyls were semiaquatic, although some were almost fully terrestrial, returning to the water only to breed. These temnospondyls were some of the first vertebrates fully adapted t ...

Evergreen Formation
The Evergreen Formation is a Pliensbachian to Toarcian geologic formation of the Surat Basin in New South Wales and Queensland, eastern Australia. Traditionally it has been considered to be a unit whose age has been calculated in between the Pliensbachian and Toarcian stages of the Early Jurassic, with some layers suggested to reach the Aalenian stage of the Middle Jurassic, yet modern data has found that an Early Pliensbachian to Latest Toarcian age is more possible. The formation was named due to the "Evergreen Shales", defined with a lower unit, the Boxvale Sandstone, and a partially coeval, partially younger upper unit, the Westgrove Ironstone Member. This unit overlies the Hettangian-Sinemurian In the geologic timescale, the Sinemurian is an age (geology), age and stage (stratigraphy), stage in the Early Jurassic, Early or Lower Jurassic epoch (geology), Epoch or series (stratigraphy), Series.

Banksiops
''Banksiops'' is an extinct genus of temnospondyl amphibian in the family Brachyopidae, recovered from the Knocklofty Formation, Tasmania. The type species, ''Blinasaurus townrowi'', Cosgriff, 1974, was published as ''Banksia townrowi'' Warren & Marsicano, 1998 in a revision that erected this genus, a name emended to ''Banksiops townrowi'' Warren & Marsicano, 2000 in a subsequent note. The authors Anne Warren and Claudia Marscicano were alerted to another animal, a species of mite, that had used the name to commemorate the acarologist Nathan Banks. The genus name ''Banksia'', still current for the flowering plants ''Banksia'' (named for Joseph Banks), was proposed by the palaeontologists Warren and Marsicano for the geologist Max Banks.

Batrachosaurus
''Batrachosaurus'' is an extinct genus of prehistoric brachyopoid amphibian that lived in Germany during the Middle Triassic (Ladinian). The genus was named by Joseph Fitzinger in 1837 and the type species, ''B. jaegeri'', was named three years later in 1840. It may have been the same animal as ''Mastodonsaurus''.

Vigilius (genus)
''Vigilius'' is an extinct genus of brachyopid temnospondyl amphibian from the Triassic of Arizona. It is known from the single type species ''Vigilius wellesi''. The holotype specimen of ''Vigilius'' is a skull labelled UCMP 36199. The skull was found in an area alongside Arizona State Route 64 overlooking the Grand Canyon. It came from a layer of the Early Triassic Moenkopi Formation. The skull was described by paleontologists Samuel Paul Welles and Richard Estes in 1969 and attributed to a new genus and species of brachyopid called '' Hadrokkosaurus bradyi''. The holotype of ''Hadrokkosaurus'' was an isolated lower jaw. In 2000, paleontologists Anne Warren and Claudia Marsicano suggested that the lower jaw and skull represent two different species, as they were found over apart and come from two animals of different size. Warren and Marsicano assigned the skull the a new genus and species ''Vigilius wellesi''. The genus name comes from the Latin word ''vigilia'' meaning "keep ...
