Scientists have identified a new species of tiny dinosaur in Japan.

The discovery was made in the city of Tamba-Sasayama, in the country's Hyogo Prefecture.

Experts say the dinosaur was related to the triceratops - but it was much smaller in size, measuring around 3ft in length and 10kg in weight.

Palaeontologists have named the new species Sasayamagnomus saegusai, and say it belonged to a group of plant-eating dinosaurs called ceratopsians.

The discovery includes 17 bones, most of which belong to a single individual.

Experts say the thin fossils likely meant that the Sasayamagnomus was a young dinosaur.

Even though it belonged to a group of dinosaurs called ceratopsians, it looked very different.

Ceratopsians are known for their large horns and big frills on their heads - which the newly discovered dinosaur didn't have.

The species thrived in the Northern Hemisphere from the late Jurassic period through to the Cretaceous period.

Scientists say the discovery is the furthest east that a ceratopsian dinosaur has been found.

Researchers think that the species may have originated in Asia, before moving to North America around 110 million years ago.
