Magnirostris, from the Latin magnus "large" and rostrum "beak", is the name given to a genus of dinosaur from the Late Campanian epoch in the Late Cretaceous. It was a ceratopsian which lived in Inner Mongolia in China. It is distinguished from other protoceratopsids by its large beak (hence the name) and incipient orbital horn cores.

Discovery and species[]

Magnirostris dodsoni was described by You and Dong Zhiming in 2003, from a near-complete skull collected from the Bayan Mandahu area in Inner Mongolia, China by the Sino-Canadian Dinosaur Project. It was named after Peter Dodson, a paleontologist.

It may be only a variant of Bagaceratops, and the incipient horn cores may be an artifact of preservation.[1]
