Melanorosaurus
''Melanorosaurus'' (meaning "Black Mountain Lizard", from the Greek ''melas/μέλας'', "black", ''oros/ὄρος'', "mountain" + ''sauros/σαῦρος'', "lizard"), is a genus of basal sauropodomorph dinosaur that lived during the Late Triassic period. A herbivore from South Africa, it had a large body and sturdy limbs, suggesting it moved about on all fours. Limb bones were massive and weighty, like sauropod limb bones.
==Discovery and species==
The type specimens, syntypes SAM 3449 and SAM 3450, were described and named in 1924 by Sidney Henry Haughton. They were collected from the Triassic Lower Elliot Formation, dating to the early Norian, on the north slope of the Thaba 'Nyama (Black Mountain) in Transkei, South Africa.〔S.H. Haughton, 1924, "The fauna and stratigraphy of the Stormberg Series", ''Annals of the South African Museum'' 12 : 323-497〕 The first complete skull of ''Melanorosaurus'' was described in 2007.〔Yates, Adam M., "The first complete skull of the Triassic dinosaur ''Melanorosaurus'' Haughton (Sauropodomorpha: Anchisauria)". In Barrett & Batten (eds.), ''Evolution and Palaeobiology'' (2007), pp. 9–55.〕 Two species are known: ''M. readi'', the type species, and ''M. thabanensis'' named in 1993 by François-Xavier Gauffre, based on holotype MNHN LES-16, a femur found in the Jurassic Upper Elliot Formation.〔F.-X. Gauffre, 1993, "The most recent Melanorosauridae (Saurischia, Prosauropoda), Lower Jurassic of Lesotho, with remarks on the prosauropod phylogeny", ''Neues Jahrbuch für Geologie und Paläontologie Monatshefte'' 1993(11): 648-654〕
