Jiangjunosaurus was a plated dinosaur that munched on plants in what is now China. It had a double row of round or diamond-shaped plates on its neck and a beak-like chin for snipping leaves.1

酷東西

趣味知識

Jiangjunosaurus had large holes in the sides of its neck vertebrae that scientists think were for veins, not air sacs like in some other dinosaurs.1

Its teeth were wide and symmetrical, with seven tiny bumps (denticles) on each edge, perfect for shredding plants.1

The only known fossil is a subadult, meaning this dinosaur was not fully grown when it died.1

Jiangjunosaurus may have been hunted by the large meat-eating dinosaur Sinraptor, which lived in the same area.1

Its neck plates were probably arranged in two rows, like other stegosaurs, and were thicker at the base than at the top.1

Jiangjunosaurus lived about 160 million years ago, during the Late Jurassic period.1

發現: Jiangjunosaurus was named in 2007 by Jia Chengkai, Catherine Foster, Xu Xing, and James Clark, based on a nearly complete skeleton found in the Shishugou Formation of Xinjiang, China.1 2
仍有爭議: Scientists are still debating exactly where Jiangjunosaurus fits on the stegosaur family tree, with some studies placing it as a primitive stegosaurid and others grouping it with Chinese stegosaurines like Wuerhosaurus.1
