Bagaceratops rozhdestvenskyi (meaning "small-horned face") is an extinct genus of small Ceratopsian dinosaur that lived in what is now Mongolia around 80 million years ago, during the Late Cretaceous. [1]

Although emerging late in the reign of the dinosaurs, Bagaceratops had a fairly primitive anatomy and kept the small body size that characterized early ceratopsians; including a tail with neural spines that are longer and are notably thinner; akin to a modern Theropod Spinosaurus.[2]

Bagaceratops grew to an adult size of about 1 meter (3.3 feet) long, 50 centimeters (1.6 feet) high, and weighed around 22 kilograms (50 lbs).[1]


Bagaceratops belonged to the Ceratopsian, a group of herbivorous dinosaurs with parrot-like beak which thrived in North America and Asia during the Cretaceous period, which ended roughly 66 million years ago.


Bagaceratops, like all known ceratopsian species, it is interpreted as a herbivorous dinosaur.
