Shantungosaurus

Shantungosaurus, meaning “Shandong lizard,” is a genus of flat-headed hadrosaurid dinosaur from the Wangshi Formation of the Late Cretaceous Period. It was discovered in 1964 in Shandong Peninsula, China. Based on material collected to date, it is very similar to Edmontosaurus.

Shantungosaurus is one of the longest and largest known hadrosaurids. The complete skeleton of a medium-sized specimen is mounted at the Geological Institute of China in Beijing. It measures 48.3 feet long. The skull itself measures 5.3 feet long. The weight of this genus is estimated to be up to 18 tons.

This dinosaur had an unusually long tail, thought to counterbalance the weight of its body at the hips. Like all hadrosaurids its beak was toothless, but its jaws were packed with about 1,500 tiny chewing teeth. A large hole near the nostrils may have been covered by a loose flap that could be inflated with air to make sounds.
