Figure 14 in The Lower Jurassic ornithischian dinosaur Heterodontosaurus tucki Crompton & Charig, 1962: cranial anatomy, functional morphology, taxonomy, and relationships

Figure 14. Heterodontosaurus tucki Crompton & Charig, 1962. Attempted reconstruction of the skull in occipital view. The post-temporal fenestra (pof) appears to be reduced to a narrow channel that enters the body of the neurocranium between the parietal, supraoccipital and (perhaps the squamosal more posteriorly). The smaller, but discrete vascular opening on the paroccipital wing is assumed to have served for passage of parts of the cranial vascular system (Romer, 1956). The indented regions (?pn) on the lower lateral corner of the paroccipital wing, and the other on the rear surface of the quadrate shaft, medial to the quadrate (paraquadratic) foramen, hint at the presence of cranial pneumatism (Witmer, 1997).
