Fun facts

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
