Fun facts
Barilium was first thought to be a species of Iguanodon, called Iguanodon dawsoni, before scientists gave it its own name in 2010.1
Its fossils come from rocks that are between about 137 and 121 million years old, from the Early Cretaceous period.3
Barilium had a very large and strong hip bone (ilium), which is why it was named 'heavy hip'.1
This dinosaur is known from only a few fossils, including parts of the spine, hips, and legs.3
Some scientists think Barilium might be the same as other dinosaurs named Kukufeldia, Sellacoxa, and Torilion, but others disagree.3
Barilium lived alongside other dinosaurs like Hypselospinus and Mantellisaurus in ancient England.1
