About Adelolophus
What it was like
Adelolophus was a duck-billed dinosaur from the branch of hadrosaurs that carried hollow crests. It is known only from a broken upper jaw bone, so the shape of its crest is unknown, which is where its name comes from.
Its world
It lived in the Late Cretaceous in what is now Utah, in the United States. Its fossil comes from the Wahweap Formation, where it shared the land with the tyrannosaur Lythronax and the horned Diabloceratops and Machairoceratops.
How it was found
Gates and colleagues named Adelolophus in 2014, from a single find. It is one of the oldest crested hadrosaurs from North America.
