Magnirostris, from the Latin magnus "large" and rostrum "beak", is the name given to a genus of dinosaur from the upper Campanian stage in the Upper 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 palaeontologist.

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

Paleoecology

Magnirostris lived in deserts with dunes. Other dinosaurs discovered in the Bayan Mandahu include Protoceratops helleninkorhinus, another primitive ceratopsian, and possibly Velociraptor mongoliensis, a small predatory theropod.[2]
