About Eolambia
What it was like
Eolambia was a plant eater about 6 meters (20 feet) long, an early relative of the duck-billed dinosaurs. It had a beak and rows of grinding teeth, and it could walk on two or four legs.
It was first thought to be an early crested hadrosaur, which is where its name comes from, but later studies place it just outside the hadrosaur family.
Its world
It lived in the Late Cretaceous in what is now Utah, in the United States. Its bones come from the Cedar Mountain Formation.
How it was found
Kirkland named Eolambia in 1998. It is known from 12 finds, including young and adult animals.
