Malawisaurus was a fairly large sauropod that lived during the Lower Cretaceous epoch of Malawi and belonged to the Titanosauria clade. It was a short-faced, armoured titanosaur that could grow up to 16 meters in length and weighed about 10.000 kg! Osteoderms have been found, which would indicate that its skin was (partly) covered in scutes, scales or spikes. It is also one of the few titanosaurs from which skull material has been found.
M. dixeyi was discovered in 1923 and since then, its genus has been changed multiple times, like Gigantosaurus, Tornieria and Janenschia. The holotype of Malawisaurus is a tail vertebra.
