趣味知識

Bagaceratops had no teeth at the front of its upper jaw, unlike its relative Protoceratops.1

It lived about 72 to 71 million years ago, near the end of the age of dinosaurs.1

Scientists once thought that fossils of Bagaceratops were several different dinosaurs, like Gobiceratops and Magnirostris, but now they think those are just Bagaceratops.1

Bagaceratops had a small frill on its head, much smaller than the frills of later horned dinosaurs.1

Its skull was more triangular than that of its close cousin Protoceratops.1
