Bagaceratops
Bagaceratops, meaning "small-horned face" , is a genus of ceratopsian dinosaur that lived in what is now Mongolia around 80 million years ago, during the Late Cretaceous...

; it has been referred to Bagaceratopidae or the Neoceratopsia. The name platyceratops is derived from Greek, and means "flat horned face".

The type specimen is Platyceratops tatarinovi, described by Aliafanov in 2003.

Classification

Platyceratops belonged to the Ceratopsia (the name is Greek
Ancient Greek
Ancient Greek is the stage of the Greek language in the periods spanning the times c. 9th–6th centuries BC, , c. 5th–4th centuries BC , and the c. 3rd century BC – 6th century AD of ancient Greece and the ancient world; being predated in the 2nd millennium BC by Mycenaean Greek...

 during the Cretaceous Period, which ended roughly 65 million years ago. All ceratopsians became extinct at the end of this era.

It may be only a variant of Bagaceratops.

Diet

Platyceratops, like all ceratopsians, was a herbivore
Herbivore
Herbivores are organisms that are anatomically and physiologically adapted to eat plant-based foods. Herbivory is a form of consumption in which an organism principally eats autotrophs such as plants, algae and photosynthesizing bacteria. More generally, organisms that feed on autotrophs in...

. During the Cretaceous, flowering plants were "geographically limited on the landscape", and so it is likely that this dinosaur fed on the predominant plants of the era: ferns, cycads and conifers. It would have used its sharp ceratopsian beak to bite off the leaves or needles.
