Melanorosaurus, which means “Black Mountain Lizard”, is a basal sauropodomorph dinosaur genus that lived in the Late Triassic. It was a South African herbivore with a large body and strong limbs that suggested it could move on all fours. Its limb bones, which were large and heavy, reminded me of sauropod leg bones.

Melanorosaurus’ skull measured 250mm. The skull measured approximately 250 mm in length. Premaxilla had four teeth, which is a characteristic of primitive sauropodomorphs. The maxilla had 19 teeth per side of the jaw.

Melanorosaurus measured approximately 8 meters (26 feet) in length and weighed 1.3 metric tons (1.3 long tonnes).

Haughton described and named the type specimens, syntypes SAM3449 and SAM 3345, in 1924. They were found in the Triassic Lower Elliott Formation, which dates to the early Norian and is located on the north slopes of Thaba ‘Nyama (Black Mountain), in Transkei, South Africa. In 2007, NM QR3314 was the first complete skull to be referred to Melanorosaurus. This specimen, however, comes from the Upper Elliot and is not comparable to the Melanorosaurus material and NM QR1551, making its reference to the genus unworkable.

Gauffre named Melanorosaurus thabanensis in 1993 based on holotype MNHN LES-16 which is a femur from the Upper Triassic lower Elliot Formation. A recent review of the material revealed that the femur and six other bones cannot be referred to Melanorosaurus. Therefore, Meroktenos Thabanensis was created.
