Xiangyunloong
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
Xiangyunloong had a short neck but a very long and powerful tail, which is unusual for early sauropodomorphs.2
Its tail was so strong that it could act as a counterbalance, helping the dinosaur stand on two legs to feed.2
Scientists think Xiangyunloong represents an early stage of gigantism, or getting very big, in sauropodomorphs.2
Xiangyunloong lived about 200 million years ago during the Early Jurassic period.4
The fossil of Xiangyunloong was found about 200 kilometers west of the famous Lufeng dinosaur fossil sites in China.2
Xiangyunloong is known from a partial skeleton that includes neck bones, back bones, tail bones, and hip bones.2
