Adelolophus is known only from a single broken maxilla, which is the upper jaw bone.1 2

Its name means 'unknown crest' because scientists do not know what its crest looked like.1 2

It lived about 78 million years ago during the Late Cretaceous period.1 4

Adelolophus is a lambeosaurine, a group of duck-billed dinosaurs with hollow crests on their heads.1 4

It is closely related to Parasaurolophus, which had a long, tube-like crest.1

The only known fossil of Adelolophus was found in the Wahweap Formation of southern Utah.1 4

Adelolophus shared its home with other dinosaurs like the horned Diabloceratops and the tyrannosaur Lythronax.1 2

The environment where Adelolophus lived was wet and swampy, near the edge of a sea.1

關於 Adelolophus 最常被問的問題

?How big was Adelolophus?

Nobody knows for sure, because only a single upper jaw bone (maxilla) has been found. Scientists estimate it was a medium-sized duck-billed dinosaur, but its exact size is unknown.1 2

?What did Adelolophus eat?

It was a plant-eater. As a duck-billed dinosaur (hadrosaur), it likely ate tough plants like ferns and cycads, using its beak-like mouth and grinding teeth.1

?Did Adelolophus have a crest?

Yes, it was a lambeosaurine, a group of duck-billed dinosaurs with hollow head crests. However, its crest is unknown because the only fossil found is a jaw bone, so its name means 'unknown crest'.1 4

?When did Adelolophus live?

It lived about 78 million years ago, during the Late Cretaceous period. It is the oldest known crested duck-bill from North America.1
