Datousaurus was a long-necked plant-eater that lived in China during the Middle Jurassic. It had a big, deep skull for a sauropod and may have used its height to reach high branches.1 2

酷東西

趣味知識

Datousaurus lived alongside other sauropods like Shunosaurus and Omeisaurus, as well as the early stegosaur Huayangosaurus.1

Its name is a pun on the Chinese words 'da tou', meaning 'big head', because it had a large skull for a sauropod.1

Only two partial skeletons have been found, and neither had a skull attached, though one skull was found nearby.1

Its vertebrae were elongated, giving it a higher reach than its relative Shunosaurus, so they may have fed at different heights to avoid competition.1

The species name bashanensis comes from a poetic phrase for the mountains and rivers of Sichuan, where it was discovered.1

Fossils of Datousaurus are rare, which scientists think means it may not have lived in big herds like some other sauropods.1

你們都在問

關於 Datousaurus 最常被問的問題

?How big was Datousaurus?

It was about 15 metres (49 feet) long, though some estimates say 10 to 13.9 metres (33 to 46 feet).2 1

?What did Datousaurus eat?

It was a plant-eater (herbivore). Its spoon-shaped teeth helped it eat different plants, possibly from high branches.1 2

?Why did Datousaurus have a big head?

Its name means 'big head' in Chinese because it had a deep, large skull for a sauropod. Scientists are not sure why, but it may have helped it eat tough plants.1

?Did Datousaurus live in herds?

Probably not. Its fossils are rare, so scientists think it may not have lived in big groups like some other sauropods.1
