酷東西

趣味知識

Ouranosaurus is the only known horned ornithopod dinosaur, with small rounded horns in front of its eyes.1

Its snout was toothless and covered by a horny beak, like a duck's bill.1

Two nearly complete skeletons were found in Niger in 1965 and 1970, and a third partial specimen came from Cameroon.1 2

Ouranosaurus lived in a river delta alongside other dinosaurs like the huge crocodile Sarcosuchus and the meat-eater Suchomimus.1

It had 22 tooth positions in each jaw, for a total of 88 cheek teeth that formed a continuous grinding surface.1

The name Ouranosaurus means 'brave lizard' in Greek, and the species name nigeriensis refers to the country of Niger.1

你們都在問

關於 Ouranosaurus 最常被問的問題

?How big was Ouranosaurus?

About 7 to 8.3 metres long and weighed around 2.2 metric tons. That is roughly the length of a school bus and the weight of a small car.1 3

?Did Ouranosaurus have a sail on its back?

Yes, it had a large sail on its back made of long, wide neural spines. This sail spanned its back.1

?What did Ouranosaurus eat?

It was a plant-eater that used its cheek teeth to chew tough plants like leaves, fruit, and seeds. Its wide beak also suggests it could eat large amounts of low-quality food.1

?Where did Ouranosaurus live?

It lived in what is now Niger and Cameroon in Africa during the Early Cretaceous. It lived in a river delta environment alongside other dinosaurs.1

?When did Ouranosaurus go extinct?

It lived during the Aptian stage of the Early Cretaceous, about 125 to 113 million years ago. It died out long before the end of the dinosaurs.1

?Was Ouranosaurus a dinosaur?

Yes, it was a herbivorous basal hadrosauriform dinosaur. It is not a pterosaur or marine reptile.1

?Did Ouranosaurus have horns?

Yes, it had small rounded horns in front of its eyes, making it the only known horned ornithopod dinosaur.1

?How fast could Ouranosaurus run?

Scientists do not know its exact speed. It was a large, plant-eating dinosaur with a stiff back, so it was probably not very fast.1
