Magnirostris dodsoni


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 palaeontologist.

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