Longneck

With a length of up to 28 meters, Diplodocus is the longest among all of the dinosaurs that have been found as complete specimens. Its neck and tail were longer than those of other long-necked types, such as Brachiosaurus, for example. Despite its enormous size, Diplodocus only weighed about ten tons, thanks to its air-filled vertebrae. The Diplodocus skeleton in the Senckenberg Nature Museum in Frankfurt is the only original skeleton of this dinosaur species on display anywhere outside of the USA.
