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.[1] Dating to the late Toarcian at approximately 176.6 ma.[2] Siderops was large, with a skull width 70 cm (28 in) wide and a total length of 2.6–2.7 m (8.5–8.9 ft).[3][4]
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.[1] Shown below is a cladogram of Brachyopoidea adapted from Warren et al. (1983) and Ruta et al. (2007).[1][5]
