Utuntu dushimishije

Yizhousaurus is one of the most complete early sauropodiform dinosaurs ever found, with a nearly whole skull and skeleton.1

Its skull had a short snout and a high, dome-shaped profile, which is unusual for early long-necked dinosaurs.2

The holotype skeleton was discovered in 2002 and excavated over about a month in October and November.1

Yizhousaurus lived during the Sinemurian age of the Early Jurassic, about 199 to 193 million years ago.3

Its name was first used in a 2010 scientific meeting, but it was not officially described until 2018.1

The fourth and fifth tail vertebrae of the holotype are fused together, which scientists think was a result of disease or injury.2
