酷東西

趣味知識

Amurosaurus is named after the Amur River, which forms the border between Russia and China.1

Most of the bones found in its bonebed belong to young Amurosaurus, not adults.1

Theropod teeth are common in the bonebed, and many bones have tooth marks, showing that predators or scavengers chewed on them.1

Amurosaurus had a unique S-shaped curve in its lower arm bone, the ulna.1

Although the crest bones are missing, the skull roof shows it likely had a hollow crest like other lambeosaurines.1

A dinosaur once called Sahaliyania is now thought to be the same as Amurosaurus.1 3

Amurosaurus had a relatively large brain compared to some other plant-eaters, which might mean it lived in groups.1
