Helioceratops
Helioceratops was a small, plant-eating dinosaur that lived about 100 million years ago in what is now China. It had a short lower jaw and walked on four legs. Its name means 'sun horned face' because scientists think horned dinosaurs like it first appeared in the East, where the sun rises.1

Сонирхолтой баримтууд
Helioceratops is known from only two jaw bones: a right lower jaw (the holotype) and a left upper jaw (the paratype). They were found close together and may belong to the same animal.1
Its lower jaw is very short and deep. The tooth row is only 60% longer than the height of the jawbone.1
The teeth of Helioceratops have an unusual pattern of ridges: up to nine ridges in front of the main ridge but only four behind it.1
Helioceratops lived during the Albian to Cenomanian stages, about 100 million years ago, at the boundary between the Early and Late Cretaceous.1
Scientists think Helioceratops is a close relative of Auroraceratops, which means 'dawn horned face'.1

?What did Helioceratops eat?
Helioceratops was a herbivore, meaning it ate plants. It lived on land and likely shared its habitat with another plant-eating dinosaur called Changchunsaurus.1
?When did Helioceratops live?
Helioceratops lived about 100 million years ago, during the Albian to Cenomanian stages, which is the boundary between the Early and Late Cretaceous. Its fossils were found in the Quantou Formation in China.14
?Why is it called Helioceratops?
The name means 'sun horned face' because scientists think horned dinosaurs first appeared in the East, where the sun rises. It also refers to its close relationship with Auroraceratops, the 'dawn horned face'.1

- Scientists are not sure whether Helioceratops had horns. No horn cores have been found, but it is a ceratopsian, so it may have had small horns on its face.1
