Diet Herbivore
Quaesitosaurus lived during the Late Cretaceous Period, about 85 million years ago in what is now Mongolia. Only the skull of this large quadruped herbivore has been found. It strongly resembles that of another gigantic sauropod of the southern Gobi, Nemegtosaurus. Quaesitosaurus skull had a much narrower snout and an unusually slanted canal posterior to the skull. This anatomical feature is suggestive of the dinosaur to have an excellent sense of hearing.
