Field notes

About Mosaiceratops

What it was like

Mosaiceratops was a small horned dinosaur with a beak and no horns. It had a mix of old and new features, like a mosaic, which gave it its name.

Its world

It lived in the Late Cretaceous, in what is now China. It comes from the Xiaguan Formation, where the sauropod Baotianmansaurus was also found.

How it was found

Zheng and colleagues named Mosaiceratops in 2015. The type species is Mosaiceratops azumai.

Lived alongside

Found in the same rock formations

A rock formation can hold fossils laid down millions of years apart, so not every animal here met Mosaiceratops.

The evidence

The science behind Mosaiceratops

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

From its own fossils

  • A partial skull and skeleton preserve vertebrae, arm bones, hips, hind legs and parts of the feet.
  • The front of the upper jaw has a sharp, toothless cutting edge, with chewing teeth farther back.
  • The lower leg is longer than the thigh, and the feet are slender with pointed claws.

Borrowed from relatives

  • Missing parts of the skull can be restored by comparison with small ceratopsians such as Liaoceratops and Archaeoceratops.

Still unknown

  • Its skin covering and color.
  • How its head and body changed as it grew.
  • Its precise place among early ceratopsian branches.
