About Nanningosaurus

What it was like

Nanningosaurus was a plant eater related to the duck-billed dinosaurs. Its known bones include parts of the skull and lower jaw, an upper arm bone and a hip bone.

Its world

It lived in the Late Cretaceous in what is now southern China.

How it was found

Mo and colleagues named Nanningosaurus in 2007, from a single find. Its name comes from a nearby city.

The evidence

The science behind Nanningosaurus

Which parts of the picture come from its own bones, and which come from its relatives.

From its own fossils

  • Parts of the skull and lower jaw, an upper arm bone and a hip bone of a plant-eating dinosaur related to the duck-billed dinosaurs. The type specimen includes a left lower jaw and a loose tooth from the lower jaw.
  • Its upper jaw has a tall, sharply peaked projection, and its lower-jaw teeth carry a winding main ridge and a smaller side ridge. The tall prong at the back of the lower jaw, where jaw muscles attached, tilts slightly forward and has a rounded top.
  • The upper arm bone was slender with a low, rounded crest, and a long bone in the hip was curved near its lower end.

Borrowed from relatives

  • The missing front of the head, the neck and the shoulders are restored by comparison with Gobihadros, a well-preserved early relative of the duck-billed dinosaurs.

Still unknown

  • Whether its head carried a crest, and what shape it had.
  • Its skin covering and color.
  • Its place in the family tree. The first study grouped it with the crested duck-billed dinosaurs, while later studies placed it outside the duck-billed dinosaur family, and a recent one found it to be that family's closest relative.
