名字的意思： “Yunyang lizard”1

吃：肉肉食恐龍侏羅紀早期到侏羅紀中期

Yunyangosaurus was a meat-eating dinosaur that lived in what is now China during the Middle Jurassic. It was about the size of a car and probably hunted smaller animals. Scientists think it might be an early relative of big predators like Megalosaurus.2 4

酷東西

趣味知識

Yunyangosaurus was named in 2020, making it a relatively new dinosaur discovery.4

Only one partial skeleton has been found, including eleven back bones and some ribs.2

The fossil was found in the Xintiangou Formation, a rock layer that has not yielded many dinosaur fossils.2

Yunyangosaurus had a combination of features that scientists have not seen in other theropods, like a special shape in its neck bones.2

It was a sub-adult when it died, meaning it was not fully grown.2

Yunyangosaurus might belong to a group called megalosauroids, which includes some of the largest Jurassic predators.1 2
