Magnirostris is a little-known genus of the bird pelvic dinosaur (Ornithischia) from the group of the Ceratopsia .

From magnirostris only an almost complete is far skull known of the of bagaceratops resembled. This dinosaur was characterized by the robust rostral bone at the tip of the upper jaw, which resulted in an enlarged beak. There were small bony bumps above the eyes. Like all ceratopsians, this dinosaur was herbivorous.

The fossil remains of Magnirostris were discovered in the Bayan Mandahu region of Inner Mongolia ( China ) and first described in 2003 . The generic name is derived from the Latin words magnus (= "large") and rostrum (= "beak"). Type species and the only known species is M. dodsoni - the specific epithet honors the paleontologist Peter Dodson. The finds are dated in the Upper Cretaceous ( Campanium ).

Magnirostris is systematically seen by its first descriptors as a close relative of Bagaceratops and classified like this in the Protoceratopsidae . According to some researchers, however, Magnirostris could only be a synonym for Bagaceratops .
