W. Gilmore. 1914. Smithsonian Miscellaneous Collections 63:1-10 Other References: Sampson, 1995 This ceratopsian specimen was collected in 1913, and represents a juvenile individual. It has been considered a “baby” Styracosaurus but unfortunately its true identity cannot be determined with certainty. The young of different ceratopsian species often look similar, because they lack the characteristic horns and spikes seen in the adults.
