Prettige feite
Arenysaurus is one of the most complete and best-dated dinosaur fossils from the very end of the Cretaceous period.1
Its fossils were found in a small village called Arén, and the townspeople helped the scientists dig them out.1
Arenysaurus belonged to a group called lambeosaurines, which often had hollow, decorative crests on their skulls.1
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
Scientists think Arenysaurus was a rather early member of the lambeosaurine family, and it was closely related to dinosaurs from Asia.2
This dinosaur lived about 66 million years ago, right at the end of the Cretaceous, and died out in the big extinction event.1
