Quaesitosaurus (meaning "abnormal or extraordinary lizard") was a huge, long-necked, whip-tailed, plant-eating dinosaur that was found in the Gobi Desert in Mongolia. Quaesitosaurus may have been about 75 feet (23 m) long. This sauropod dinosaur lived during the late Cretaceous Period, roughly 85-80 million years ago. Quaesitosaurus may be the same as Nemegtosaurus. This environment was semi-arid during the Mesozoic Era.
