名字的意思： “Huayang lizard, after an old name for Sichuan, China”1

吃：植物劍龍類侏羅紀中期到侏羅紀晚期

Huayangosaurus was a small, plant-eating dinosaur that lived about 165 million years ago in what is now China. It had a double row of bony plates and spikes along its back and tail, which it probably used for defense and showing off. This early stegosaur was much smaller than its famous relative Stegosaurus.1

酷東西

趣味知識

Huayangosaurus had a beak with teeth in the front of its mouth, a feature that later stegosaurs lost.2

Its bony plates had vein-like cavities that may have helped control body temperature or change color to scare off predators or attract mates.2

Huayangosaurus lived about 20 million years before Stegosaurus appeared in North America.1

It had two pairs of long spikes at the end of its tail, forming a weapon called a thagomizer.1

Fossils of at least twelve individual Huayangosaurus were found together in the Dashanpu Quarry.1

Its front legs were longer than those of later stegosaurs, and it had a broader skull.2
