Fun facts

1

Shantungosaurus is the largest known duck-billed dinosaur, even bigger than other hadrosaurs like Edmontosaurus.2

2

Its skull alone was about 1.63 metres (5.3 feet) long, which is longer than a tall adult human.2

3

It had around 1,500 tiny teeth in its jaws, which it used to chew tough plants.2

4

A big hole near its nostrils might have been covered by a loose flap of skin that could puff up to make sounds.2

5

Some fossils once named Zhuchengosaurus and Huaxiaosaurus are now thought to be the same animal as Shantungosaurus, just younger or older individuals.24

6

It lived between about 77 and 71 million years ago, during the Late Cretaceous period.21

Most asked questions about Shantungosaurus

?How big was Shantungosaurus?

It was about 15 to 17 metres long and weighed around 13 to 16 metric tons. Some scientists think it was a bit smaller, about 15 metres and 13 metric tons.21

?What did Shantungosaurus eat?

It was a plant-eater, eating tough, low-growing plants like pine branches and flowering plants. It used its 1,500 tiny teeth to chew them up.32

?When did Shantungosaurus live?

It lived during the Late Cretaceous Period, about 78 to 74 million years ago. Some sources say 77 to 71 million years ago.12

?Where was Shantungosaurus found?

Its fossils were found in the Shandong Peninsula in China. It was first described by paleontologist Hu Chengzhi in 1973.32

?Was Shantungosaurus bigger than T. rex?

Shantungosaurus was longer than T. rex, but T. rex was a meat eater and Shantungosaurus was a plant eater. Shantungosaurus could be up to 17 metres long, while T. rex was about 12 metres long.2

?Did Shantungosaurus have feathers?

No, scientists have not found any evidence of feathers on Shantungosaurus. It was a duck-billed dinosaur with scaly skin, and its hands were webbed.3

?Could Shantungosaurus swim?

It probably could swim, because it often browsed along the shores of lakes and other bodies of water. Its webbed hands might have helped it paddle.3

?Why did Shantungosaurus have a duck bill?

Its beak was toothless and shaped like a duck's bill, which helped it feed selectively on plants. It had a large hole near its nostrils that might have been covered by a loose flap of skin, possibly to make sounds.32

Myth buster

Myth: Some people think Shantungosaurus was a meat-eater because it was so big.

Truth: Actually, Shantungosaurus was a plant-eater, as shown by its duck-billed skull and grinding teeth.21
