關於 Brachylophosaurus 最常被問的問題

?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

迷思破解王

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

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