Nemegtosaurus (meaning “reptile from the Nemegt”) was a sauropod dinosaur from the Late Cretaceous Period of what is now Mongolia. Measuring an estimated 12 – 13 m long and weighing 20 t, it was named after the Nemegt Basin in the Gobi Desert, where the remains — a single skull — were found. The skull resembles diplodocoids in being long and low, with pencil-shaped teeth. However, recent work has shown that Nemegtosaurus is in fact a titanosaur, closely related to animals such as Saltasaurus, Alamosaurus, and Rapetosaurus.
