酷東西

趣味知識

Breviceratops had teeth in the front of its upper jaw, which is a primitive feature shared with Protoceratops andrewsi.1

It had an opening in its skull in front of the eye socket, called an antorbital fenestra, which was narrow and straight-shaped.1

The skull ended in a moderately pronounced neck frill, a common feature among protoceratopsids.1

The first fossils were found in the 1960s by a Polish expedition to the Gobi Desert.1

Breviceratops was originally named as a species of Protoceratops, but was given its own genus in 1990.1

Some scientists think Breviceratops might be a juvenile stage of Bagaceratops, but the holotype has primitive teeth that don't match.1

關於 Breviceratops 最常被問的問題

?How big was Breviceratops?

Nobody knows for sure because only juvenile fossils have been found. The known skull is small, suggesting it was a small dinosaur.1

?What did Breviceratops eat?

It was a plant-eater (herbivore). It used its parrot-like beak to bite off plants.1 4

?Is Breviceratops a dinosaur?

Yes, it is a dinosaur. It belongs to the group Ceratopsia, which includes horned, parrot-beaked dinosaurs.1

?When did Breviceratops live?

It lived during the Late Cretaceous period, about 83 to 72 million years ago.1 4

迷思破解王

迷思： Breviceratops is the same as Bagaceratops.

真相： Some scientists have suggested that, but the holotype from Khulsan has primitive premaxillary teeth that are different from Bagaceratops, so most researchers now treat it as a separate genus.1
