Datos curiosos

1

Arenysaurus is one of the most complete and best-dated dinosaur fossils from the very end of the Cretaceous period.1

2

Its fossils were found in a small village called Arén, and the townspeople helped the scientists dig them out.1

3

Arenysaurus belonged to a group called lambeosaurines, which often had hollow, decorative crests on their skulls.1

4

The original bones are kept in a museum built in the town of Arén, along with a replica showing how the skeleton was found.1

5

Scientists think Arenysaurus was a rather early member of the lambeosaurine family, and it was closely related to dinosaurs from Asia.2

6

This dinosaur lived about 66 million years ago, right at the end of the Cretaceous, and died out in the big extinction event.1
