Schematized parietals of centrosaurine ceratopsids in dorsal view,
showing possible homologies for the first four epiparietal loci. A. Alberta−
ceratops nesmoi Ryan, 2007. B. Spinops sternbergorum gen. et sp. nov.
C. Centrosaurus apertus Lambe, 1902. D. Styracosaurus albertensis Lambe,
1913. E. Rubeosaurus ovatus Gilmore, 1930. F. Einiosaurus procurvicornus
Sampson, 1995. Numbers indicate locus positions. For A and B, the numbers
on the right side of the parietal indicate numbering under the “traditional”
scheme; numbers on the left side indicate numbering under the revised
scheme proposed here. Locus numbering is the same in both the traditional
and revised schemes for C, D, E, and F, and are thus presented only on the left
side of the parietal for those taxa. Not to scale.
