Fig. 28. The dorsocaudal surface of the paroccipital process (pop) of Alioramus altai (IGM 100/1844). Note the thin process of the parietal (pa) that participates in the process and the relatively large foramen (ctra), which communicates directly with an internal cavity of the caudal tympanic recess.
