Prettige feite

Haolong's skin had large overlapping scales on its tail and smaller bumpy scales around its neck and chest.2

The spikes on Haolong were hollow and made of keratin, the same stuff as your fingernails.2

Scientists could see the preserved nuclei of skin cells in Haolong's spikes under a microscope.2

Haolong's spikes were different from the feathers of meat-eating dinosaurs and the spines of modern lizards.1 2

The only known Haolong skeleton is nearly complete and still connected together, which is very rare.1 2

Haolong lived about 125 million years ago during the Early Cretaceous period.4 1

The spikes might have helped Haolong stay cool or feel its surroundings, not just defend itself.1 2

julle het gevra

Mees gevraagde vrae oor Haolong

?How big was Haolong?

About 2.45 metres (8 feet) long. That is about the size of a small motorcycle.1

?Did Haolong have feathers?

No. Its skin had scales and hollow spikes made of keratin, not feathers.1 2

?What did Haolong eat?

It was a plant-eater, so it ate leaves and other plants.3

?When did Haolong live?

About 125 million years ago, during the Early Cretaceous period.1

?Where was Haolong found?

In Liaoning Province, northeastern China, in the Yixian Formation.1

?Why did Haolong have spikes?

Mostly to scare away predators, like a porcupine. They might also have helped with cooling or sensing touch.1 2

Mite-breker

Mite: Haolong was a spiky dinosaur like a Stegosaurus.

Waarheid: Haolong's spikes were made of keratin and were hollow, not bony plates. They were more like porcupine quills than the plates of Stegosaurus.1 2
