Utuntu dushimishije

Yandusaurus had large eyes, as shown by the curved jugal bone in its skull.2

Its teeth had a unique pattern of parallel vertical ridges, which Chinese researchers compared to the fingers of Buddha statues.2

The first Yandusaurus fossil was accidentally dug up by a composter machine near the Honghe dam in 1973.2

Yandusaurus had four toes on each foot and five fingers on each hand.2

The name Yandusaurus comes from Yandu, the ancient name for Zigong, which means 'salt capital' because the city was a center of salt mining.2

Scientists once thought Yandusaurus was a hypsilophodontid, but now they place it in a group called Neornithischia.2 3
