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.
