Rukwatitan bisepultus is a species of Titanosaur from Tanzania. It lived around 100 million years ago, during the middle Cretaceous. The species, which shared features with another South African species, Malawisaurus dixeyi, measured 30 feet (9.1 m) from the head to the tip of the tail, and had forelimbs that were estimated around 6.5 feet (2.0 m) long.
