Igama lithetha: “spiny dragon”1

Yayitya: IzityaloIzitya-zityalo ezinemilomoiCretaceous yokuqala

Haolong was a plant-eating dinosaur that walked on two legs and had a long tail. It had special spikes on its skin that looked a bit like porcupine quills, which might have scared away hungry predators.1 2

izinto ezimnandi

Iinyani ezimnandi

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

Umfanekiso owenziwe yi-AI: Haolong — Umfanekiso owenziwe yi-AI obonisa indlela Haolong esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: 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

Inyaniso ngeentsomi

Intsomi: Haolong was a spiky dinosaur like a Stegosaurus.

Inyaniso: 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

Kwiingcali zeedayinaso

Igama lenzululwazi: Haolong
Inikwe igama ngu:: Huang et al. 20264
Iqela: Izitya-zityalo ezinemilomo
Usapho / iclade: Hadrosauroidea4
Ukuhlelwa: Ornithischia > Ornithopoda > Iguanodontia4
Ubudala bamatye: 126 ukuya ku-121 izigidi zeminyaka (Barremian)4
Izakhiwo zamatye: Yixian4
Amazwe: iTshayina4
Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: Haolong was named in 2026 by a team of scientists led by J. Huang. The name honors the famous Chinese paleontologist Dong Zhiming.1 4
Kusaxoxwa ngayo: Scientists are not sure if adult Haolong also had spikes, because the only known fossil is a juvenile.1
