Shantungosaurus

Shantungosaurus was a huge  hadrosaur found in the Upper Cretaceous Wangshi Formation of the Shandong Peninsula in China. It was the largest known hadrosaur.

The skeleton of a medium-sized individual mounted at the Geological Institute of China in Beijing is  in length, and the type skull is  long. The weight of this genus is estimated at up to . With a composite mounted skeleton 17 meters long (55.7 ft) it is the largest known ornithischian and the largest non-sauropod dinosaur. 

It had an unusually long tail, presumably to counterbalance the great weight of the body at the animal's hips.

Like all hadrosaurs its beak was toothless, but its jaws were packed with around 1,500 tiny chewing teeth. A large hole near its nostrils may have been covered by a loose flap, which could be inflated to make sounds.

First described in 1973, Shantungosaurus is known from  five incomplete skeletons.
