趣味知識

Ruyangosaurus had a thigh bone (femur) that was 207 centimetres long, longer than a tall adult person.1

Its shin bone (tibia) was 127 centimetres long, showing it was a truly giant dinosaur.1

Ruyangosaurus lived during the Early Cretaceous period, about 121 to 100 million years ago.2

It shared its home with other dinosaurs like Xianshanosaurus, Yunmenglong, and the small meat-eater Luoyanggia.1

The name Ruyangosaurus means 'Ruyang County lizard', after the place in China where its bones were found.1

Some scientists think Ruyangosaurus was a type of titanosaur, a group of huge long-necked dinosaurs.1
