In Depth

       Quaesitosaurus is only known from a partial skull of what appears to have been a diplodocid sauropod dinosaur,‭ ‬however it has also drawn similarity to Nemegtosaurus that is also from the same area and also only known from a skull.‭ ‬If true then Quaesitosaurus may also be connected Opisthocoelicaudia which is only known from a headless body,‭ ‬that has been credited with possibly representing the missing body of Nemegtosaurus.‭
