Xiangyunloong

Say it: shyang-YOON-loong
Name means: “auspicious cloud dragon”1
Ate: PlantsLong-necksEarly Jurassic

Xiangyunloong was a big, plant-eating dinosaur that lived in what is now China. It had a short neck but a very long and strong tail, which helped it balance its heavy body. This dinosaur shows that not all early long-necked dinosaurs had long necks!2

Fun facts

1

Xiangyunloong had a short neck but a very long and powerful tail, which is unusual for early sauropodomorphs.2

2

Its tail was so strong that it could act as a counterbalance, helping the dinosaur stand on two legs to feed.2

3

Scientists think Xiangyunloong represents an early stage of gigantism, or getting very big, in sauropodomorphs.2

4

Xiangyunloong lived about 200 million years ago during the Early Jurassic period.4

5

The fossil of Xiangyunloong was found about 200 kilometers west of the famous Lufeng dinosaur fossil sites in China.2

6

Xiangyunloong is known from a partial skeleton that includes neck bones, back bones, tail bones, and hip bones.2
