Prettige feite

Corythosaurus is named after its crest, which looks like a Corinthian helmet worn by ancient Greek soldiers.1

The crest was hollow and connected to the nose. Scientists think Corythosaurus used it to make loud calls, like a trombone.1

One nearly complete skeleton was found with impressions of its skin, showing it had polygonal scales.1

Corythosaurus lived alongside other dinosaurs like the tyrannosaur Gorgosaurus and the horned dinosaur Centrosaurus.1

The first Corythosaurus fossil was discovered in 1911 by Barnum Brown in Alberta, Canada.1

Corythosaurus had a beak that was shallow and delicate, so it probably ate only the softest plants.1

Mees gevraagde vrae oor Corythosaurus

?How big was Corythosaurus?

Corythosaurus was about 7.7 to 9 metres (25 to 30 feet) long and weighed around 2.5 to 3.8 tonnes (2.8 to 4.2 short tons).1 2

?What did Corythosaurus eat?

Corythosaurus was a herbivore that ate soft plants. One fossil even had its last meal preserved, which included conifer needles, seeds, twigs, and fruits.1

?Did Corythosaurus have feathers?

No, Corythosaurus did not have feathers. Fossils show it had polygonal scales on its skin, like a reptile.1 4

?Why did Corythosaurus have a crest?

Scientists think the hollow crest was used for making loud calls, like a trombone. It helped Corythosaurus communicate with others.1

?When did Corythosaurus live?

Corythosaurus lived during the Late Cretaceous period, about 77 to 75 million years ago.1 2

?Where was Corythosaurus found?

Corythosaurus fossils have been found in Canada (Alberta) and the United States.2 1

?Was Corythosaurus a dinosaur?

Yes, Corythosaurus was a type of duck-billed dinosaur called a hadrosaur.1 2

?Could Corythosaurus swim?

Nobody knows for sure, but like many duck-billed dinosaurs, it may have been able to swim. Its webbed feet are not confirmed from fossils.1
