Figure 7. Linear bivariate logarithmic plot of examined pachycephalosaurids. All square = Sphaerotholus edmontonenesis; stars = S. goodwini; circles = S. buchholtzae; triangles = Foraminacephale brevis; diamond = Prenocephale prenes. L:W = length to width of the frontoparietal dome; T:W = thickness to width of the frontoparietal dome; L:T = length to thickness of the frontoparietal dome.
