Figure 11 in The Lower Jurassic ornithischian dinosaur Heterodontosaurus tucki Crompton & Charig, 1962: cranial anatomy, functional morphology, taxonomy, and relationships
Figure 11. Heterodontosaurus tucki Crompton & Charig, 1962. Attempted reconstruction of the skull and the articulated right lower jaw in left lateral view, revealed following sagittal sectioning and removal of the right vomer. Note: the contours of the floor of the braincase and its internal walls are conjectural; the thickness and anterior extent of the supraoccipital are unknown and have been illustrated very conservatively; the anatomy of the contacts between the vomer, palatine, pterygoid and maxilla in the anterior-central part of the snout are conjectural. For full list of abbreviations see end of paper.

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).
