S9·E5 George's Photo Finish

Today is the big unveiling of the Ankylosaurus dinosaur skeleton at the Museum, but it's missing a leg! George and the Man with the Yellow Hat thought they delivered all 4 bones. Where did the 4th bone go? Fortunately, Mr. Quint took pictures on their way to the Museum. Maybe the photos can lead them to the bone...if they can only figure out which order to put them in.
