Yizhousaurus was an early long-necked dinosaur that lived in what is now China during the Early Jurassic. It had a beautifully preserved skull, which is rare for its kind. This plant-eater walked on four legs and grew to about the size of a small bus.2 1

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

Aurkikuntza: The only known skeleton of Yizhousaurus was found in 2002 near Duwafang Village in Yunnan, China. It was named and described by scientists in 2018, after being mentioned at a conference in 2010.1 2
Oraindik eztabaidagai: Scientists are still debating exactly where Yizhousaurus sits on the family tree of sauropodiforms, because its skeleton has a mix of old and new features.2
