酷東西

趣味知識

Claosaurus was first named in 1872 as Hadrosaurus agilis, but was given its own genus in 1890.1

The fossils of Claosaurus were found in a chalk bed that was once the floor of a shallow sea.2

Claosaurus is one of the earliest hadrosauroids, the group that includes duck-billed dinosaurs.1

Only a partial skull and some bones of the body have been found, so scientists are not sure how big it really was.1

One estimate says Claosaurus was about 3.7 metres (12 feet) long and weighed as much as a lion.1

Claosaurus probably died on land, then was washed into the sea and sank to the bottom.2
