Arenysaurus by hyrotrioskjan-d42ndot
Arenysaurus is a hadrosaur from late Cretaceous Europe. It grew to over 5 meters (16 feet) and was likely common prey for animals in the area. It had a small crest in about the middle section of its head. Crests such as this one are common in hadrosaurs, specifically the lambeosaurine hadrosaurs, but were not present in every hadrosaur.
