Yuxisaurus

名字的意思： “Yuxi lizard”1

吃：植物甲龍類侏羅紀早期

Yuxisaurus was an early armoured dinosaur that lived in what is now China during the Early Jurassic. It was a sturdy, slow-moving plant-eater covered in sharp spines and bony plates. This dinosaur helps scientists understand how famous armoured dinosaurs like Stegosaurus and Ankylosaurus evolved.1

酷東西

趣味知識

Yuxisaurus is the first valid armoured dinosaur ever described from the Early Jurassic of Asia.2

Its body was covered with more than 120 bony plates called osteoderms, which acted like a suit of armour.1

Unlike many early armoured dinosaurs that walked on two legs, Yuxisaurus was a heavy quadruped, walking on all fours.2

Yuxisaurus lived alongside long-necked plant-eating dinosaurs called sauropodomorphs, but it was much rarer in its ecosystem.2

The fossils of Yuxisaurus were found in rocks that were once part of a low-lying, well-watered coastal environment.2

Yuxisaurus shows that armoured dinosaurs spread across the northern hemisphere very early in their evolutionary history.1

發現: Yuxisaurus was named in 2022 by Yao and colleagues based on a partial skeleton found near Jiaojiadian village in Yunnan, China. The species name kopchicki honours a person named Kopchick.2
仍有爭議: Scientists are not sure whether Yuxisaurus was more closely related to the European armoured dinosaur Emausaurus or to the group that includes Scelidosaurus and later armoured dinosaurs.2
