Skulls of pachycephalosaurids, generalized and only vaguely implied to specific species.
The first two columns show the skulls of generalized pahcys in lateral (left) and dorsal (right) views, with some shading to make the domes pop a bit.
Arrows indicate the direction and trajectory of dome growth in ontogeny. In some Stegocephale-Prenocephale-morph taxa, there are accessory domelets on the side, thse pop up last in ontogeny, and are shown by smaller, accessory arrows.
The bottom row shows Dracorex, Stygimoloch, and Pachycephalosaurs as an ontogenetic series with similar arrows.
My infographic terror continues to spread!
This time, prompted by nothing in particular (he lied) is the question of ontogenetic metaplastic transformation.
