酷東西

趣味知識

Nasutoceratops had an enormous nose area that made up about 75% of the length of its skull in front of its eyes.1

Its horns pointed outward and forward, then curved and twisted at the tips, unlike most other horned dinosaurs.1

The frill on its head was simple and wide in the middle, without the big holes or spikes seen in many relatives.1

It lived alongside other dinosaurs like the tyrannosaur Teratophoneus and the duck-billed Gryposaurus.1

Nasutoceratops is one of the few horned dinosaurs from the southern part of the ancient continent Laramidia.1

Its name honors Alan Titus, a paleontologist who helped with fossil discoveries in the monument.1

關於 Nasutoceratops 最常被問的問題

?How big was Nasutoceratops?

?What did Nasutoceratops eat?

It was a plant-eater, like all ceratopsian dinosaurs. It used its beak to bite off leaves and other plants.2

?Why did Nasutoceratops have such long horns?

Scientists think the long, forward-curving horns may have been used for fighting or showing off, like modern cattle. They could have locked with an opponent's horns.2

?Where did Nasutoceratops live?

It lived in what is now southern Utah, USA, about 75 to 76 million years ago. That area was then part of an island continent called Laramidia.2

?When did Nasutoceratops live?

It lived during the Late Cretaceous period, about 76 to 75.5 million years ago.2

No, the sources do not mention feathers. Skin impressions were found on its arm, but they have not been described as having feathers.2

迷思破解王

迷思： Nasutoceratops had a horn on its nose like Triceratops.
