''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. Shown below is a cladogram of Brachyopoidea adapted from ''Warren et al. (1983)'' and ''Ruta et al. (2007)''. Referenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
