Holotype
USNM 7951. Collected in August 1913. The original description was by Gilmore in the Smithsonian Miscellaneous Collections, volume 63, in 1914. The type specimen consist of a partial skull and frill. In 1995 this genus was referred to Styracosaurus by Scott Sampson . It is now considered to be a juvenile Styracosaurus.
However, Dodson, Forster and Sampson in The Dinosauria II Chapter 23 \\\\\\\"Ceratopsidae\\\\\\\" page 508 state refering to Sampson, 1997 that this specimen should be regarded as a Nomen Dubium since it is based on juvenile remains that had not expressed adult features at the time of death.
