Hypsilophodon had five fingers on each hand, and one of them was opposable, like a thumb, so it could grasp branches and food.1

Its tail was stiffened by bony tendons, which helped it keep balance while running fast on two legs.1

Its teeth were self-sharpening: the upper and lower teeth rubbed together as it chewed, keeping them sharp.1

Hypsilophodon probably had cheeks, which helped it hold and chew food, just like modern plant-eaters.1 2

All the true Hypsilophodon fossils come from a single layer of rock called the Hypsilophodon Bed, on the Isle of Wight.1

It lived about 126 million years ago, during the Early Cretaceous period.1 2

tias dumondas

Las dumondas las pli frequentas davart Hypsilophodon

?How big was Hypsilophodon?

It was about 1.5 to 2 metres (5 to 6.5 feet) long and weighed around 20 kilograms (44 pounds).1 2

?What did Hypsilophodon eat?

It was a herbivore, eating low-growing plants like young shoots and roots. It used its sharp beak to clip vegetation and probably had cheeks to help chew.2 1

?Could Hypsilophodon climb trees?

No, scientists used to think it climbed trees, but we now know it lived on the ground and was a fast runner.2 1

?How fast could Hypsilophodon run?

It was built for running with long legs, a stiff tail for balance, and a light body, but no exact speed is known.2 1

?Did Hypsilophodon have feathers?

No, there is no evidence that Hypsilophodon had feathers. It was a small ornithischian dinosaur with scaly skin.1

?Where did Hypsilophodon live?

It lived in what is now England, specifically on the Isle of Wight, during the Early Cretaceous period about 126 million years ago.2 1

?Was Hypsilophodon bigger than a chicken?

Yes, it was about the size of a large turkey or a small deer, much bigger than a chicken.2

?Did Hypsilophodon live in groups?

Yes, several fossils were found together, so some experts think it lived in groups, like deer.2

Chatschader da mitus

Mitus: Some people thought Hypsilophodon lived in trees, like a climbing dinosaur.

Vardad: Scientists now know it lived on the ground and was built for running, not climbing.2
