Fun facts

Yueosaurus is known from only one partial skeleton, which includes bones from the neck, back, tail, shoulder, hip, and limbs.1

It lived during the Cretaceous Period, between about 113 and 94 million years ago.2

Yueosaurus was a basal neornithischian, meaning it was an early relative of later plant-eating dinosaurs like Iguanodon.1

Its fossils were found in the Liangtoutang Formation in Tiantai County, Zhejiang.1

Scientists think Yueosaurus might belong to the Jeholosauridae family, a group of small ornithopods from Asia.1
