Melanorosaurus readi

Melanorosaurus was a medium size sauropodomorph from the Upper Triassic of South Africa, represented by the species M. readi. With its sturdy apparence, it was probably quadrupedal. Melanorosaurus was long known only from postcranial elements until a complete skull is described in 2007. A second species from the Upper Elliot Formation (Lower Jurassic) in Lesotho, M. thabanensis, has been described from an isolated right femur.
