Fun facts
Yunganglong lived about 100 to 84 million years ago, during the early Late Cretaceous.3
The only known skeleton is a partial one, including parts of the skull, backbone, hips, and leg bones.1
Yunganglong was a basal hadrosauroid, meaning it was an early cousin of the duck-billed dinosaurs like Edmontosaurus.2
The skull of Yunganglong was wide and low, with a width of 37 cm (14.6 in) between its paroccipital processes.2
Its fossils were found alongside remains of ankylosaurs and ceratopsians, other plant-eating dinosaurs.1
The name Yunganglong honors the Yungang Grottoes, ancient Buddhist cave temples about 50 km east of the fossil site.1
