Vagaceratops (Va-ga-seh-rah-tops), Wandering Horned Face, lived in the Late Cretaceous of North America. Vagaceratops was similar to other chasmosaurs in that it had a comparatively long neck frill and reduced nasal horn.


Genera and Species

Classification: ‬Ornithischia,‭ ‬Ceratopsia,‭ ‬Ceratopsidae,‭ ‬Chasmosaurinae

Species: V. irvinensis.

Senior synonyms: Chasmosaurus irvinensis


Vagaceratops had a broad, flat, relatively unadorned frill. The frill is distinctive in being square shaped, with a row of ten, forward-curving hornlets along the back. The nose horn was short and brow horns tare reduced to low bosses. It was originally classified as a species of Chasmosaurus but reclassified in 2010. Adult chasmosaurs had broad long frills without spines that are open. The nose horn is small but the brow horns are prominent. The jaws were designed to act like shears chopping up tough plant material. Triceratops is the best known and last of the family.

Size Length 3 m (15 ft). Weight 1.2 tons. Behavior It would have been social like other chasmosaurs. Vagaceratops fed on low to medium height vegetation. The beak would have been more effective than horns for defense.

History of Discovery

Discovered by Holmes, Forster, Ryan and Shepherd in 2001. It is known from a partial skeleton with skull and 2 other skulls.


Found in North America, Canada,‭ ‬Alberta‭, in semi arid plains with forested rivers with a short rainy season.
