趣味知識

Saurolophus is one of the few dinosaurs known from both North America and Asia, which suggests they could cross land bridges.1

The first nearly complete dinosaur skeleton ever found in Canada was a Saurolophus, discovered in 1911.1

A huge bonebed in Mongolia called Dragon's Tomb contains at least 21 Saurolophus individuals, showing they lived in groups.1

Its teeth were packed into dental batteries, with hundreds of teeth that were constantly replaced, so it could chew tough plants.1

Saurolophus could reach food up to about 4 meters (13 feet) above the ground, thanks to its long neck and body.1

The crest on its head was a solid spike, not a hollow tube like in some other duck-billed dinosaurs.1

關於 Saurolophus 最常被問的問題

?How big was Saurolophus?

Saurolophus osborni was about 8.2 to 8.5 meters (27 to 28 feet) long, while the larger Mongolian species S. angustirostris reached about 12 to 13 meters (39 to 43 feet) long and weighed up to 11 tonnes (12 short tons).1 2

?What did Saurolophus eat?

Saurolophus was a herbivore, eating plants like conifer needles, twigs, and seeds. It had a toothless beak and hundreds of cheek teeth for grinding tough plant material.1 3

?Did Saurolophus have a crest?

Yes, Saurolophus had a distinctive spike-like crest on its head, made of nasal bones, which pointed up and back. It may have been used for display or heat regulation.1

?Could Saurolophus swim?

The sources do not say Saurolophus could swim. It was a land dinosaur that could walk on two legs or all fours, but no swimming adaptations are mentioned.1 3

?When did Saurolophus live?

Saurolophus lived during the Late Cretaceous, about 71.5 to 66 million years ago.1 2

?Where was Saurolophus found?

Saurolophus fossils have been found in North America (Canada, USA) and Asia (Mongolia, China). It is one of the few dinosaurs known from multiple continents.1 2

?Was Saurolophus a dinosaur?

Yes, Saurolophus was a dinosaur, specifically a hadrosaurid (duck-billed) dinosaur. It was an ornithopod, a plant-eating dinosaur.1 2

?Did Saurolophus live in herds?

Yes, evidence from a bonebed called Dragon's Tomb in Mongolia suggests Saurolophus lived in groups, with at least 21 individuals found together.1

迷思破解王

迷思： Some people think Saurolophus could swim in the ocean.

真相： It lived near rivers and lakes, but it was a land animal that walked and ate plants on land.1
