1930
 		 Charles W. Gilmore describes as a specimen which came from the Two Medicine Formation in Montana as a new species, Styracosaurus ovatus. In retrospect and with the benefit of hindsight, this is probably a mistake, as more recent research (2010) suggests it should be placed in a separate genus, "Rubeosaurus".

1937
 		 A paper describing Barnum Brown's find, assigns it to a new species Styracosaurus parksi. In retrospect and with the benefit of hindsight, this is probably a mistake, as it most likely an example of Styracosaurus albertensis.
 
2010
 		 McDonald and Horner suggest that Gilmore's Styracosaurus ovatus should actually be a different genus, which they call "Rubeosaurus".
