Prettige feite

A nearly complete skeleton nicknamed 'Elvis' was found in Montana in 1994, and it is about 95% complete.1

A famous fossil called 'Leonardo' preserved stomach contents, showing what Brachylophosaurus actually ate.1

Brachylophosaurus had a flat, bony crest on its head, but scientists are not sure what it was used for.1

A bonebed in Montana contains at least 800 specimens of Brachylophosaurus, showing it lived in large groups.1

Brachylophosaurus lived between 83.6 and 72.2 million years ago, during the Campanian age.3

Skin impressions have been found on some Brachylophosaurus fossils, helping scientists understand its appearance.1

Mees gevraagde vrae oor Brachylophosaurus

?How big was Brachylophosaurus?

About 7 metres (23 feet) long. That is roughly the length of a large SUV or a small school bus.2

?What did Brachylophosaurus eat?

It was a herbivore that ate leaves, conifers, ferns, algae, liverworts and flowering plants like magnolias. It was both a browser and a grazer.1

?Did Brachylophosaurus have feathers?

No, it did not have feathers. Its skin impressions show small, polygonal scales and a row of triangular scales along its back.1 4

?Why did Brachylophosaurus have a crest?

Scientists are not sure. Some think it was used for pushing contests, but the crest may not have been strong enough for that.1

?When did Brachylophosaurus live?

It lived during the Late Cretaceous period, about 78.5 to 77.6 million years ago.1

?Is Brachylophosaurus a dinosaur?

Yes, it is a dinosaur. It is a type of hadrosaurid, or duck-billed dinosaur.2 1

Mite-breker

Mite: Brachylophosaurus had a hollow crest like some other duck-billed dinosaurs.

Waarheid: Its crest was solid and flat, not hollow, and its purpose is still debated.1
